Description: Steps:[QC Short Description] docking demo is broken, was ok in delphi7 [QC Description] the docking demo behaves strangely sometimes, is broken other times, compared to delphi7 version of the docking demo. tab-sheet host: using the delphi7 demo, create a floating host with some tabs. drag a new client over the tabsheets, and you get only one dock-rect allowed - drop the new client and it's added as a new page. good. now try with the d2006 demo. when you drag the new client over, you get additional possibilities for dock-rects: top, bottom, left, right, centre. all of those do weird stuff. the new client is not added in a logical way to the others. instead, the new client and one of the old ones gets combined, and kicked out as a floating pair. conjoin host: using delphi7 demo, create the following arrangement of tiles in a floating host: wide rectangle on top, tall rectangles underneath on the left and on the right: AA BC BC now dock a new client into the bottom half of rectangle C, to make this arrangement: AA BC BD works fine. now try with the D2006 demo. when dropping D onto C, the host ejects C, and we're left with two floating hosts, one containing A and

1. open ($BDS)\Demos\DelphiWin32\VCLWin32\Docking\dockex.dpr 2. click the "White" toolbutton. 3. move the "White" window to a convenient location 4. click the "Blue" toolbutton. 5. dock the"Blue" window into the Right-hand Half of the white window. 6. click the "Green" toolbutton 7. dock the "Green" window into the Right-hand Half of the docked blue window. 8. click the "Lime" toolbutton 9. dock the "Lime" window into the Right-hand Half of the docked blue window. Exp: All four windows will be docked together Act: The green and lime windows jump out of the other docked group (See image attachments 1_xxxx 2_xxxx 3_xxxx) Note that if the lime window is into either the white or the blue window results are as expected. Close app and retry with tabbed docking: 1. click the "White" toolbutton. 2. move the "White" window to a convenient location 3. click the "Blue" toolbutton. 4. dock the"Blue" window into the center of the white window to tab-dock. 5. click the "Green" toolbutton 6. dock the "Green" window into the center of the tab-docked blue window to add as a tab. Exp: The green window will be added as a third tab to the group Act: The blue and green windows jump out of the white window and form their own tabbed duo. (See image attachments A_xxxx - D_xxxx) Tested in RAD Studio 2007 with identical results (using the demo from BDS2006, since I don't see it in the RAD Studio distribution)

Description: Steps:[QC Short Description] RichEdit demo project and ITE compatibility [QC Description] Why was the RichEdit sample project that ships with Delphi XE in C:\Users\Public\Documents\RAD Studio\8.0\Samples\Delphi\VCL\RichEdit was modified compared to the same demo that ships with Delphi 2010 (and older versions) in C:\Users\Public\Documents\RAD Studio\7.0\Demos\DelphiWin32\VCLWin32\RichEdit Previously, the demo consisted of a RichEdit project and three resource DLL files that would produce RichEdit.DEU, RichEdit.ENU, and RichEdit.FRA, in the same way the Integrated Language Environment does, and quite compatible with it. The "new" (and in my view degraded) version in Delphi XE produces the RichEdit.exe executable, but resource DLL projects that have been manually renamed to RichEditDEU.dll, RichEditENU.dll, and RichEditFRA.dll. No more locale as file extention, but part of the filename in Delphi XE. Huh? Why this change? As a consequence of this manual renaming, someone also had to go through the trouble of changing the implementation in the reinit.pas unit, making it incompatible with the ITE and ETM language translation tools in Delphi. I really do not understand why this was needed... QC Entry 88996

Open the RichEdit sample project, and try to add a new language using Project | Language - Add Language. It will not recognise or pick up the existing languages in the Delphi XE edition of the sample project. Compare this to the Delphi 2010 edition, which worked fine and was compatible with the ITE.

Description: Steps:[QC Short Description] swscanf documentation missing format specifiers, esp. for wide string [QC Description] The documentation page for sscanf, swscanf states "Note: For details on format specifiers, see scanf.", but there is no such info on the scanf page. A more serious problem is that there is nothing on the swscanf page that informs the programmer that swscanf considers the "s" (little s) specifier to refer to a two-byte character (wchar_t), rather than requiring the capital s or "ls" (little l, little s) to indicate that a pointer to a two-byte character is being passed. QC Entry 76397

String str = "2We"; wchar_t daystr[4]; int no; // this works int resultLittleS = swscanf(str.c_str(), L"%1d%2s", &no, daystr); // this does not int resultBigS = swscanf(str.c_str(), L"%1d%2S", &no, daystr); (by providing these steps, I am not suggesting that the behavior is incorrect, but rather that this is the behavior that should be documented. Obviously, this is C++ code, not Delphi, but I could not find a C++ Builder documentation section)

Description: Steps:[QC Short Description] TMaskEdit Documentation [QC Description] Documentation on the basic TMaskEdit does not assist in creating a custom mask. The sample masks do not include a currency mask, and I am trying to create a simple dollars and cents mask. (I wonder if there is a reason this common need is not included in the masks?) The documentation contains the following, but it never actually explains the mask.

Place a TMaskEdit component on a form, place the cursor in the Editmask property, open the property editor and press F1.

"Define your own masks for the edit box. You can use special character to specify the mask; for a listing of those characters, see the Mask.TCustomMaskEdit.EditMask property." In fact, the "listing of those characters" is not found at the location indicated - or anywhere else that I could find. QC Entry 90523 QC #: Date Reported: Area:85170 6/6/2010 Documentation

Description: Steps:[QC Short Description] German translation of System.Copy is a bit misleading [QC Description] The translation of this help topic:

ms-help://borland.bds5/delphivclwin32/System_Copy.html to German is a bit misleading in the following sentence (this applies to the docwiki XE versio as well): The substring or subarray is a unique copy (that is, it does not share memory with S; if the elements of the array are pointers or objects, these are not copied as well.) Der Teilstring oder das Teil-Array ist eine eindeutige Kopie (d.h., Speicher wird nicht gemeinsam mit S genutzt, obwohl Zeiger- oder Objektelemente des Arrays nicht kopiert werden).

Description: Steps:[QC Short Description] F1 in Build pane no longer shows help for errors or warnings [QC Description] In past versions of Delphi, pressing F1 in the build results window (or pane) used to bring up Delphi's Help showing more information about the selected error or warning. See Steps. Added by Sysop <<<<<<<<<<<<<<<< The help content for E2081 is missing. E2081 Assignment to FOR-Loop variable 'I' >>>>>>>>>>>>>>>> QC Entry 80493

In Delphi 2010... 1) Go to File > New > VCL Forms Application - Delphi 2) Place a Button on the form 3) Double-click Button1 to get to its OnClick event handler 4) Declare the following var section: var I, J: Integer; S: String; 5) Paste or write the following code: for I := 0 to 10 do if I = 3 then Inc( I ) else S := S + IntToStr( I ) + ' '; 6) Compile the project. 7) The first message you should receive is something like this: [DCC Error] Unit1.pas(33): E2081 Assignment to FOR-Loop variable 'I' 8) Click the error and press F1. Instead of showing you page E2081 in the help, you instead get a generic help page with the title "DCC32.EXE, the Delphi Command Line Compiler". Nothing about your specific problem is highlighted. However, if you type E2081 in the Index page of the Help, you'll see the page exists. 9) To further illustrate this problem, delete the lines starting with "if" and ending in "else" so that you have one statement in the for loop. 10) Compile the project. 11) The first message should be something like: [DCC Hint] Unit1.pas(28): H2164 Variable 'J' is declared but never used in 'TForm1.Button1Click' 12) Again, click the message and press F1 and you get the same help page, instead of the H2164 help page. Typing H2164 in the Index tab of the help will show you the page you really wanted to see. This is broken functionality as of Delphi 2010. I hadn't seen it before this version. Please fix it. :)

Description: Steps:[QC Short Description] Deploy to the Cloud - missing information [QC Description] The online help page should mention that the destination folder should be a shared folder on the remote EC2 server (I missed that step earlier). QC Entry 88549

The EC2 cloud machine it just a server, and you need to define a directory on that machine where your files will end up being deployed to. So, if I want to deploy to a directory called "Bob", I need to make a directory on the server, and make it shareable under the name "Bob", and need to make sure Administrator can write to it. OK, so I've made a directory Bob, set up sharing and made sure Administrator can write to it. When you login to the EC2 machine, that login will connect to the Windows Shared directory (not very secure, I know) and upload the files. This may mean that you need to disable the firewall for a while (in order to allow the incoming connection). From my laptop, I could deploy quite easily to the EC2 shared folder Icreated at the server, and my file is already up there as well now. The missing bit of information from the on-line Help was the fact that the destination folder on the EC2 machine should be a shared folder (so the upload can take place).


Description: Steps:[QC Short Description] Wrong mentioning of NIL for key parameter [QC Description] ms-help://embarcadero.rs_xe/vcl/Registry.TRegistry.OpenKeyReadOnly.html contains (at least in the german verion) the following sentence: Wenn Key nil (Delphi) oder NULL (C++) ist, wird die Eigenschaft CurrentKey auf den in der Eigenschaft RootKey festgelegten Schl·sel gesetzt. In English this means that if the key parameter of the function is set to NIL CurrentKey will be set to RootKey. Since key is a string it cannot be NIL in Delphi. It can only be empty! ('') QC Entry 90576

Open ms-help://embarcadero.rs_xe/vcl/Registry.TRegistry.OpenKeyReadOnly.html and read it. Then create a TRegistry instance in your code and try to call OpenKeyReadOnly with NIL as parameter. Compile and see the compiler complaining that key is a string and no pointer.

The other four are documented though. QC Entry 96105

1. open a vcl application project 2. click file/new/active x 3. select automation object to start the wizard 4. look at the options for the threading modell (5 options) 5. open the help topic 6. look at how the threading model is documented (4 options only)


Description: Steps:[QC Short Description] Online Help is incomplete and also nearly unusable [QC Description] TField's OnGetText event has a boolean parameter named DisplayText. But the online help has no reference to what this parameter is all about. With hope, when you select the link to TFieldGetTextEvent, yes... you get: This is type DB.TFieldGetTextEvent. Now, the stranger thing is this; TField.OnGetText Event description section has two paragraphs. These two paragraphs are ,word by word, an exact duplication of, Delphi 3's 1st and 3rd paragraphs (no typo, 1997 Delphi 3). Guess what? The second paragraph of Delphi 3 documents all the missing information. From Delphi 3 help; "The Sender parameter is the field component. The Text parameter receives the formatted text that is used by the DisplayText or Text property. The DisplayText parameter indicates whether the text will be used for display purposes only, or whether the string will be used for editing purposes."

See description

Not being able to provide a decent documentation for a 13 years old product, with 3 major updates after more than 1 years have passed till its offering is one thing, crippling existing documentation is an other thing. Note that, this report is not about TField's OnGetText, it is about documentation. I have refferred to Delphi 3's help countless times. Unfortunately I do not own a more recent Delphi than the 3rd one and it is missing lots of new technologies. In short, I want decent documentation, and I want it with Delphi 2007, not with a future version. Is it too much to ask for?

Description: Steps:[QC Short Description] Class documentation missing hierarchy [QC Description] In Delphi 2009 and earlier, class documentation included a hierarchy list documenting a class' ancestors and providing links to those ancestor classes. In D2010 help, links to ancestors are inconsistent, and usually only reference the parent class. QC Entry 77416

QC #: Date Reported: Area:54822 11/14/2007 Documentation\Online Help\VCL

Description: Steps:[QC Short Description] VCL properties and methods are not indexed [QC Description] When you press F1 and go into the index tab and search for a method or property of a vcl component, let us say TControl for example, you will get a bunch of useless references to Windows documentation and other non relevant pages. I would expect that since the VCL is the primary programming library in Delphi, that I would be able to find all the methods and properties of all components indexed and easily available for quick reference. QC Entry 54822

For example I want to find the documentation of TControl.Parent. Press F1. Go into the Index tab. Type in "Parent" in the Look for: edit. Expected result: All references to Parent method displayed. What I got: A bunch of useless stuff.

39886 2/3/2007 Documentation\Online Help\Main help

Description: Steps:[QC Short Description] TStringList.IndexOf docs are incorrect [QC Description] The Help for TStringList.IndexOf states "Call IndexOf to obtain the position of the first occurrence of a string that matches S." But this statement is correct ONLY if TStringList.Sorted=False and/or

1. Create a TStringList. 2. Set Sorted=True and Duplicates=dupIgnore. 3. Add 10 duplicate strings to the list 4. Call IndexOf() with the same string as was added to the list. The IndexOf return value should be 0 according to the docs/Help, but it will be an integer near the middle of the TStringList.Count, probably 5.

TStringList.Duplicates=dupIgnore or dupError. Otherwise (when Sorted=True and Duplicates=dupAccept) IndexOf merely returns the index of *any* string in the list which matches the parameter S of the IndexOf() call. Why? Because if Sorted=True, calling IndexOf() internally calls Find(), and Find uses a binary search to locate *any* string matching the passed string parameter. In a TStringList where duplicates are allowed, this will not always be the *first* matching string. QC Entry 39886 QC #: Date Reported: Area:

Description: Steps:[QC Short Description] SO Suffix used for BPL not DCP [QC Description] Struggling to understand and use the Namespace and SO Suffix features. I honestly do not know whether this is as-designed or a bug, because the documentation is at the level of what to type instead of giving conceptual guidance. For me these issues are key. Perhaps not for others. 1. DPK compiles and creates DCP and BPL of different names. The BPL uses the SO Suffix (as I expected). The DCP does not. (Should it? Could you document that?) YES - done. 2. Related issue: the true difference between Default Namespace and Namespace Prefix is unclear. I think the documentation needs some use cases here. I can give you my use case : We maintain some open-source code, and update it occasionally. Use ZaphodsMap as the example. ZaphodsMap classes are used in Rubicon and WebHub. I want to use the SO Suffix to differentiate releases, so that we can help people avoid problems based on interface changes. I want to use the namespace idea to differentiate ZaphodsMap-in-Rubicn from ZaphodsMap-in-WebHub so that both products can be installed in the IDE at once, but with different source code (say Rubicon is released in August then ZaphodsMap changes then WebHub is released in September). I believe that this issue is central to massive global cooperation among component vendors. I am probably missing something ..... and/or this area is not fully tested. Please see screenshots and ask me if you want further details. I have not yet posted ZaphodsMap to CC because I wanted to sort this issue out in advance, but I can post it if anyone wants to look at specifics. Apologies if I am just being a dumb tired user. Hopefully not. QC Entry 76762

Search for namespace gives many matches, most seem to be about C++Builder eg ms-help://embarcadero.rs2010/rad/Defining_A_namespace.html Search for "so suffix" does not show me anything about the Project Options dialog or when to use it. Search for Project Options..... ms-help://embarcadero.rs2010/rad/Setting_Project_Options.html .... states the obvious about the UI with no details about which options to use when..... (Rushing now so I am probably missing some things) This page ms-help://embarcadero.rs2010/rad/Building_Packages.html says you can Add a package to a project - and that definitely does wierd things such as displaying the BPL file in hex in the editor window, and, still not making the project able to find the package. That's another story. If you want to see real trouble, try renaming a package a few times, using dots in the filename. Not sure what else to give for steps.

Description: Steps:[QC Short Description] Formatter doesnt add space after generic property declaration [QC Description] Formatting classes with generic propertys causes a small bug that leads to code, that is not easy to read and also breaks the jump to deklaration feauture. QC Entry 92494

use a class with: property Foo: TFoo<TBar> read FFoo; Formatter will do this: property Foo: TFoo<TBar>read FFoo; --> Rightclick->Search for declaration on TFoo wont work anymore


Description: Steps:[QC Short Description] Try to format this unit: unit unTest; interface type TFoo = Integer;

Formatter fails on partial range declaration [QC Description] If you have some partial value range declaration like "type TCaps='A'..'Z';" the formatter will not indent this and every following type declaration. QC Entry 92909

TCaps = 'A' .. 'Z'; TBar = Integer; type TFoo2 = Integer; implementation end. Result will look similar to the one above. TCaps and TBar not indented but TFoo and TFoo2 are. ------------ ... type TFoo = Integer; TCaps = 'A' .. 'Z'; TBar = Integer; ... ------------

Description: Steps:[QC Short Description] Formatter should differentiate method names from directives [QC Description] Methods named as some of directives are not properly capitalized. QC Entry 88896

1. Set Capitalization Options Capitalization of other words - As first occurrence Capitalization of reserved words and directives - lower case 2. Format following code unit Unit1; interface type TMyClass = class function Read: string; procedure Write(const s: string); end; implementation { TMyClass } function TMyClass.Read: string; begin end; procedure TMyClass.Write(const s: string); begin end; end. *************************** And the result will be: unit Unit1; interface type TMyClass = class function read: string; <------ SHOULD BE Read procedure write(const s: string); <----- SHOULD BE Write end; implementation { TMyClass } function TMyClass.Read: string; begin end; procedure TMyClass.Write(const s: string); begin end; end.

See attached example. Module Unit.pas [vk]Fixed in #35346. Formatter supportts now 2 types of anonymous methods: anonymous1 - in the assignment anonymous2 - in the operator (usually in function). For example R := function(a, t): Integer var i: Integer; begin Result := 0; end; and EnumFiles(10, function(r: Integer; s: String): Integer var l: String; begin Result := 0; end, 145); Example file is attached ___proj1.dpr Additional - two parameters added - "Line breaks in Anonymous Functions assignment" and "Line breaks in Anonymous Functions usage".

//Format this Source: program Project1; type TAnonMethod = reference to procedure(aParam: Boolean); procedure UseAnonMethod(AAnonMethod: TAnonMethod); begin AAnonMethod(True); end; begin UseAnonMethod( procedure(aParam: Boolean) begin if not aParam then Halt; end); end. // //Formatter will formate the source above like this: // program Project1; type TAnonMethod = reference to procedure(aParam: Boolean); procedure UseAnonMethod(AAnonMethod: TAnonMethod); begin AAnonMethod(True); end; begin UseAnonMethod( procedure(aParam: Boolean)begin if not aParam then Halt; end); end.


Description: Steps:[QC Short Description] Code Formater inserts incomplete CRLF sequence [QC Description] Under specific circumstances when formatting only the selection of the code, formatter will eat first character of the selected code and insert only CR at the and of the selection. After that not having a complete CRLF sequence in source code results in other bugs (like Error Insight and Code Completion not working properly) I think that Copyright character in Documentation region in attached sample code causes misbehavior. Other international characters cause the same misbehavior. QC Entry 93638

1. Select following options: Error Insight - on Source Options - Show Line Breaks - on Formatter Options: Keep user line breaks - false Line breaks un Uses clauses - yes 2. Open attached project 3. Open - XSpace.Engine file 4. Error Insight will show red lines under - TSomething, and all line breaks will be normal CRLF pairs 5. Select uses + Classes, XSpace.Controls, XSpace.Classes; lines 6. Press Ctrl + D to invoke formatting 7. As the result formatter will eat up "u" character from uses and add only CR at the end of the selection 8. Error Insight will now show errors in wrong lines I have also attached images of described behavior before.jpg shows code before, and after.jpg after formatting.

Description: Steps:[QC Short Description] Event handlers are inserted incorrectly [QC Description] Added by Sysop <<<<<<<<<<<<<<<<<<<< [Steps] Create a form with 2 buttons (First and Second) and one label

NOTE: My platform is actually Windows 7 64-bit, but the platform field in Quality Central doesn't have any options for Windows 7. Double clicking on a control in the form designer creates and inserts the default event handler for that control (assuming the event handler doesn't already exist). The new event handler is not being inserted correctly. It is breaking the code. Here is the code BEFORE the event handler is inserted. procedure TMainForm.jobNumberEditChange(Sender: TObject); begin ; end; procedure TMainForm.modifiedOnDateTimePickerChange(Sender: TObject); begin ; end; If I then double click on a control (any one will do, so long as it creates a new event handler), I get the following error

(Label1). Write event handlers for the buttons as follows: procedure TForm1.FirstEventClick(Sender: TObject); begin // The presence of this comment appears to be involved in the bug. Label1.Caption := 'First Button'; end; procedure TForm1.SecondEventClick(Sender: TObject); begin Label1.Caption := 'Second Button'; end; Save. Switch back to the designer and double-click the label - procedure Label1Click is created. Format the source code with Ctrl+D then save again with Ctrl+S - the empty event hander for the label is deleted by the IDE. Switch back to the designer and double-click the label again. The error message appears and the following is inserted into the code editor: procedure TForm1.FirstEventClick(Sender: TObject); begin // The presence of this comment appears to be involved in the bug. Label1.Caption := 'First Button'; end; pprocedure TForm1.Label1Click(Sender: TObject); begin end; rocedure TForm1.SecondEventClick(Sender: TObject); ... >>>>>>>>>>>>>>>>>>>> QC Entry 82194

message. Cannot find implementation of method jobNumberLabelClick. Here is the code AFTER the event handler is inserted. procedure TMainForm.jobNumberEditChange(Sender: TObject); begin ; end; pprocedure TMainForm.jobNumberLabelClick(Sender: TObject); begin end; rocedure TMainForm.modifiedOnDateTimePickerChange(Sender: TObject); begin ; end; Notice that the new event handler has actually been inserted between the 'p' and 'r' of the reserved word 'procedure' at the start of the second pre-existing method. This same error occurs if I double click next to an unassigned event in the object inspector. This is a major pain. An added problem is that the event handler is inserted in alphabetical order, so I have to go looking for it to fix it. In my opinion new event handlers should be inserted at the end of the unit where I can easily find them and then put them were I want them. At the moment I'm creating event handlers manually to avoid both the insertion error and the alphabetical issue. I have just upgraded to Delphi 2010 and I'm not at all impressed by such a fundamental operation failing, something that for me worked fine in Delphi 2009 and Delphi 7.


Description: Steps:[QC Short Description] F**** explicit properties [QC Description] Have I ever told you, what I think about the explicit properties? Please do the following: - Open Delphi 2010 - Create a new vcl forms application - Put 2 buttons on the form - Move the buttons at a bottom / right position of the form - Now think, that the form should be smaller - Really believe, that the form must be smaller - Set the anchors of the buttons to [akRight, akBottom] - Set the size of the form as small as you like - Reset the anchors of the buttons to [akLeft, akTop] - Wonder yourself, where the buttons have been gone. - Now, ask yourself: How stupid are explicit properties?

When trying to use code completion for TSearchOption in TDirectory.GetDirectories, I'd expect that code completion shows TSearchOption at the top of the list or better TSearchOption.soTopDirectoryOnly and TSearchOption.soAllDirectories as this is what the user needs to use as parameter.

Press Ctrl+Space where indicated in the example program Project1; {$APPTYPE CONSOLE} uses SysUtils, IOUtils; begin try TDirectory.GetDirectories('C:\', '*.*', // <-- CURSOR HERE except on E: Exception do Writeln(E.ClassName, ': ', E.Message); end; end.

When the user has typed "TSearchOption.", then the available identifiers will be visible, but this is too late.

88818 10/10/2010 IDE\Refactoring\Extract Superclass

Description: Steps:[QC Short Description] Extract superclass fails for class that implements interface [QC Description] If you have a class TMyClass (derived from TInterfacedObject) that implements the IMyClass interface and you want to extra a super class from it in TBase, then the TBase is derived from TInterfacedObject (which is OK), but TMyClass is only implementing IMyClass, and no longer derived from TBase. Also, TBase is declared *after* the TMyClass and IMyClass (see QC #88817 for another case where that happens). QC Entry 88818

Consider the following exampe code: type IContact = interface procedure Contact(Msg: TMessage); end; TContact = class abstract(TInterfacedObject, IContact) strict private FName: String; function GetName : String; procedure SetName(val : String); public property Name: String read GetName write SetName; procedure Contact(Msg: TMessage);virtual; abstract; end; We can create a TPerson super class which only contains a Name property and GetName and SetName methods, but without the Contact method. First, we need to select the methods or properties we want to include in the super class. For example, select the GetName and SetName methods, and then do Refactoring | Extract Superclass to get a similar dialog as we saw earlier. In that dialog, we can specify the name of the superclass and the namespace, and can also select the specified fields (unselect them if you want less, but you cannot add more like the Contact method), as well as specify which methods should be made abstract in the super class. We can also specify abstract for the Name property, but that will have no effect, of course. Unfortunately, there is a regression in Delphi XE: the effect of this dialog is that a new class TPerson is added, derived from TInterfacedObject: TPerson = class(TInterfacedObject) strict protected FName: string; procedure SetName(val: string); public function GetName: string; property Name: string read GetName write SetName; end; This is great, since although TPerson does not need to implement the IContact interface (for the Contact method), it does need to “include” the TInterfacedObject in order for it to be available for the TContact descendent class. The problem, however, is the fact that TContact now only implements the IContact interface, but does not inherit from TPerson, not does it contain the previous fields and methods that are now moved to TPerson. The definitions for IContact and TContact are a bit empty now.

QC #: Date Reported: Area:89089 10/19/2010 IDE\Refactoring\Find Unit

Description: Steps:

[QC Short Description] Refactoring "Find Unit" often does not work any more [QC Description] This problem is in a class "of intermittend" issues that do not always reproduce. Therefore do not close it before contacting the original author. Since Delphi XE, the "Find Unit" refactoring often does not work for me any more. Delphi Refactoring in Delphi has become more stable over time, so it gets harder and harder to reproduce instabilities. This particular feature goet less stable in the last release. Therefore it might need special attention: the cause might make other features unstable as well. This case reproduces it only some of the times. If I find a way to reproduce it better, I will amend the steps. I have a gut feeling that the problem is caused by the facts that: 1. the "Find Unit" refactoring sometimes is asynchronous 2. if "Find Unit" is aready running, it is not disabled in the menu. I have not found out yet the "sometimes". After the error, the IDE becomes unstable. You cannot copy/paste the error with Ctrl-C to the clipboard, hence the attachment of one of the errors (so you have an idea how the dialog looks like). Besides RAD Studio XE, I have installed the latest GExperts and Model Maker Code Explorer. Even when I have disabled those two experts, the "Find Unit" refactoring often fails. mtError Dialog Title=CodeGear RAD Studio Content=System.IO.FileLoadException: The given assembly name or codebase was invalid.

So nothing gets freed and memory consumption grows.

Description: Steps:[MSSQL] Performance degradation in multi-processor machines with SQL server driver. Multi-threaded application running on multi-processor

Test application using Northwinds database is attached. The application has a choice between dbExpress and ADO. It has a choice of thread count also. This needs to be run on a multi-processor box. Two-threads running on a two processor machine

machine is very slow when result sets from queries or stored procedures are returned. It seems like the row/field fetching is going thru critical section and blocking other threads. So the advantage of multi-threading is lost. The test application creates separate connections from each thread to the database and so they should all be independent. QC Entry 3122

96506 7/21/2011 Database\DBExpress\TSQLConnection

Description: Steps:[QC Short Description] Using DBXPool with Connect Timeout Corrupts Memory [QC Description] When my DataSnap service tries to connect to the a database where SQLServer is not available, it times out. It then waits 5 seconds and tries to connect again. The moment it calls the TSQLServer.Open method the second time, the service process is immediately terminates without warning. It doesn't even raise an exception in the Delphi debugger. The process just disappears. The Windows System Event log shows: "The ... service terminated unexpectedly" with event id 7034. If I do not set DelegateConnection to DBXPool, then every failed attempt to connect to the database raises a timeout exception. This is the behavior that I want, but I also need to use DBXPool. I created a simple program to recreate the problem, but could not get the simple programs to disappear like my production service does. However, there is still something odd happening because when I use the DBXPool as a DelegateConnection, it will timeout on the first attempt to connect, and then on the second call it will simply succeed,even though there is *no* database server avaialble and it would therefore be impossible for it to be connected. My guess is that memory is being corrupted somewhere and with my service it just happens to kill the process, but with the simple application it does not. In either case, it seems that the DBXPool is to blame. QC Entry 96506

1. Compile the desktop application 2. Stop any instances of SQLServer that are running on the local machine 3. Run the app 4. Click the first button (With DBXPool) a few times You will see it fail once, then it will show the 'connected' message even though it isn't connected. 5. Click the second button (W/O DBXPool) a few times. It will always show a timeout exception.

Description: Steps:[QC Short Description] TSQLConnection requires presence of dbxdrivers.ini [QC Description] TSQLConnection only works properly if a dbxdrivers.ini file with the right settings is present in either the application directory (where according to UAC rules a settings file shouldn't be) or in one of two locations two registry keys point to, which is problematic as well since those settings files would then be shared between different applications on the same computer which could lead to conflicts. Requiring a dbxdrivers.ini file also defeats the possibility to change parameters of a TSQLConnection isntance at runtime. It is simply bad design and was introduced after Delphi 2006 at least without any clear indication why this was necessary. This issue als is discussed here: NNTP: forums.embarcadero.com embarcadero.public.delphi.database.dbexpress:2078

1. Create a simple dbexpress application where a working db?connection is being used to fetch some records from a given database. Build the application in a way that it generates a single exe file. Build the application in such a way that it would work on a 2nd PC which doesn't have a dbxdrivers.ini 2. Ensure the application runs properly on the development PC 3. install all necessary database client software on a "fresh" PC 4. copy over your exe file and the necessary dbExpress driver dll but no dbxdrivers.ini 5. run the application on the 2nd PC and notice that it fails due to a missing dbxdrivers.ini

Please, if you can't reproduce it, call me on +44 (0)1743 453146 and I will talk you through the problem and how to replicate it! Using the new dbExpress drivers with XE and an MSSQL case sensitive database (a database with a collation that is case sensitive). As far as I can see the dbExpress code to communicate with MSSQL

Create a new SQL Server Database and set the Collation to a case sensitive option like Latin1_General_CS_AI or in fact any _CS (i.e. Case Sensitive) collation and then try to access the database tables through the Data Explorer. Errors will appear everwhere because the dbExpress code access the system table names as uppercase names even though some of them are not uppercase. The theory can be tested by navigating a case sensitive DB using Database Explorer and trying to navigate to see the fields within a table (this generates a "SQL State: 42S02, SQL Error Code: 208 Invalid object name 'SYSCOMMENTS'" because it should be looking at "syscomments" in lower case)

is using UPPER CASE table names and column names and this only works if the database is case insensitive. In actual fact the tables in question SYSCOMMENTS and SYSTYPES (and all the associated field name) should be in lowercase and the fact that it works at all is more luck than judgement. In previous versions of dbx for MSSQL the code used sp_columns_rowset to get a list of column names for a table and for some reason this has now been amended and hard coded as upper case joins (DBXMsSqlMetaDataReader.pas) This problem extends throughout the functionality of dbExpress because you can then no longer look at meta data and therefore none of the ApplyUpdates functionality works because the code cannot determine what the primary keys are etc. QC Entry 91457 QC #: Date Reported: Area:64447 7/19/2008 Database\Data Explorer

Description: Steps:[QC Short Description] add DSAuth to uses clause of ServerMethodsUnit [QC Description] If TRoleAuth type (from the DSAuth unit) is unknown, then the attribute will be ignored by the compiler, producing only a "unsupported language feature" warning. Please add the DSAuth unit to the uses clause of the ServerMethodsUnit template, so it's always there. QC Entry 88431

Part of the new authorization functionality is the ability to mark both server methods and/or the entire server method class with the TRoleAuth attribute to tell which role(s) is authorised, and which role(s) explicitly isn't. Syntax example: type {$METHODINFO ON} TServerMethods1 = class(TComponent) private { Private declarations } public { Public declarations } function EchoString(Value: string): string; [TRoleAuth('admin', 'guest')] function ReverseString(Value: string): string; end; {$METHODINFO OFF} Here, the ReverseString function is only allowed for user 'admin' while user 'guest' is not allowed to call it (and other users are not specified, so they will also be able to call it, or so it seems). When adding the attribute to the class definition, we get a compiler warning (not an error, but a warning "unsupported language feature"). The warning is caused by the fact that the compiler doesn't know about the TRoleAuth type at this point (by default, the unit DSAuth is not in the uses clause), and the actual effect is that this custom attribute is ignored, so no authorization is done on the ReverseString, and even 'guest' can call it now. Workaround: modify this particular warning ("Unsupported language feature") in the Build Configuration and turn it into an error, so people will see it as an error and not a warning. Manual Fix: add the DSAuth unit to the uses clause. Embarcadero requested fix: add the DSAuth unit to the uses clause of the ServerMethodsUnit template, so it's always there... Thanks!

Description: Steps:[QC Short Description] Make TCustomGrid.SelectionMoved virtual [QC Description] We have created a virtual grid component based on TCustomDrawGrid for our application. In our grid you can focus individual cells (goRowSelect is off) however the current focused row is highlighted. We now want to highlight the the rows which are in the selection. The only way I can see to do this is to override TCustomGrid.SelectionMoved so it can invalidate the rows included in the selection. To make this possible, could you please make the TCustomGrid.SelectionMoved() procedure virtual and give it protected visibility. This should not break any existing code. QC Entry 96892

Description: Steps:[QC Short Description] Deadlock in TThread destructor when constructor raises exception when CreateSuspended is False [QC Description] If the CreateSuspended parameter of the TThread constructor is set to False, and then any derived class constructor raises an exception, the TThread destructor deadlocks. This problem was introduced in D6 and still exists in D2009. The reason for the deadlock is because the TThread destructor does not resume the suspended OS thread when CreateSuspended is False: destructor TThread.Destroy; begin if (FThreadID <> 0) and not FFinished and not FExternalThread thenbegin Terminate; if FCreateSuspended then // <-- here Resume; <-- not called WaitFor; end; ... end; To fix this, the TThread constructor should be setting the FSuspended member to True when creating a new OS thread object (since it is always created in an suspended state), and then the destructor needs to check the FSuspended member instead of the FCreateSuspended member, ie: constructor TThread.Create(CreateSuspended: Boolean);

program ThreadDeadlockApp; {$APPTYPE CONSOLE} uses Classes, Dialogs, SysUtils; type TTestThread = class(TThread) protected procedure Execute; override; public constructor Create(CreateSuspended: Boolean); end; constructor TTestThread.Create(CreateSuspended: Boolean); begin inherited; raise Exception.Create(''); // can be any exception end; procedure TTestThread.Execute; begin end; begin try TTestThread.Create(True); except ShowMessage('ok'); // this is reached fine end; try TTestThread.Create(False); except ShowMessage('ok'); // this is never reached end; end.

Description: Steps:[QC Short Description] Make TThread handle naming the thread during debugging nicer [QC Description]

TThread uses RaiseException() to pass a name string to the debugger for displaying per-thread names in the Threads window. The generated code is not friendly to developers who use the generated TThread descendant code as a base class for other descendant classes. Those classes are not able to name themselves properly, unless they call their own RaiseException() code manually. The RaiseException() code can easily be abstracted away inside of TThread itself by adding a Name property to TThread. See the Workaround section for a possible implementation.

QC #: Date Reported: Area:86876 8/3/2010 VCL\Standard Controls\TMainMenu

Description: Steps:[QC Short Description] Incorrect painting of hot item on menu using Vista/7 themes [QC Description] Recent versions of Delphi do a decent job of supporting the new style menus introduced in Vista.

However, there is a minor flaw in the way the menu highlight is drawn. The code in Menus.pas draws the menu highlight after drawing the glyph. This results in the menu highlight being blended over the top of the glyph. In fact the opposite is what is required, namely the glyph being blended over the top of the menu highlight. This can be seen, for example, in the RAD Studio IDE which clearly is built from the same flawed Delphi code. The solution is trivial. Just move the code which draws the menu highlight (the call to DrawThemeBackground with MPI_HOT parameter) before the code which draws the glyph. Incidentally, you may be aware that Vista/7 themed menus can be obtained, with glyphs, without using owner draw code. The trick is to set MenuItemInfo.hbmpItem to be a PARGB32 bitmap in TMenuItem.AppendTo. This would, for me, be a much preferable approach to supported Vista/7 themed menus. The advantage is that using system drawn menus makes your code more robust to future releases of Windows which may change things once again. In addition, you get the system native code for greying out menu glyphs and thus making your app as native as possible.

Description: Steps:[QC Short Description] Vista disabled menu items drawn incorrectly [QC Description] This report is related to 86876. That report describes the fact that the call to DrawThemeBackground for (MENU_POPUP_ITEM, MPI_HOT) is drawn in wrong sequence. I have also realised that it is a mistake always to pass MPI_HOT. When the menu item is disabled you should pass MPI_DISABLEDHOT. This is why disabled menu items are drawn, incorrectly, with a blue hot highlight instead of being grey as nature intended. As I stated in 86876, the ideal solution would be to avoid owner draw altogether. QC Entry 89920

Description: Steps:[QC Short Description] Unwanted null characters when loadng files/streams into a TRichEdit [QC Description] When the TRichEdit.PlainText property is True, TRichEdit's LoadFrom...() methods attempt to load data as Ansi and decode it to Unicode. During that process, the data is read in chunks and each chunk is decoded. In ComCtrls.StreamLoad(), a check a made to see if a chunk ends with a #13 byte, and if so then replaces it with a #00 byte, BUT it does not adjust the chunk length accordingly, so that #00 byte gets included in the Unicode decoding, which produces a null character. The RichEdit does not display the character, but it is present in the TRichEdit.Text property. If the data has line breaks that occur at even multiples of the chunk length (2045-2046 bytes), they produce null characters. When I ran all three of the attached HTML files through the LoadFromFile() method, the #13->#00 replacement happens exactly once for each file. QC Entry 97696

The attached D2009 project includes 3 HTML files reproduce the problem. The problem still exists in later versions.

1. copy the sample program below 2. when breakpoint is hit, add data breakpoint for &p[0], and close the data breakpoint dialog 3. in the breakpoint list window, select &p[0] data breakpoint, and press Enter, this should bring you to edit dialog for this breakpoint 4. change the address to p+3 5. at this point it should prompt you for misaligned warning, hit cancel 6. two bugs here: a. make sure the current data breakpoint does not get deleted b. make sure not AV 7. press F9, it should hit the data breakpoint program Project9;

{$APPTYPE CONSOLE} uses SysUtils; var i: integer; p: PByte; begin System.GetMem(p, 100); i := 0; // add line breakpoint here p[0] := 1; writeln('abc'); // press F9 should stop here.... p[0] := 2; writeln('def'); p[3] := 3; p[4] := 4; try foo2(); foo; except on E: Exception do Writeln(E.ClassName, ': ', E.Message); end; end.

QC #: Date Reported: Area:22101 12/8/2005 Debugger\Call Stack

Description: Steps:[QC Short Description] Win32 project with packages.Call stack incomplete for errors in vcl [QC Description] I create a simple win32 project with runtime packages options checked. I have a Form, a button and in button OnClick:

Self.Controls[3].Top := 1; A statement that will raise an exception. At runtime the call stack is: kernel32.RaiseException TList.Get+$3c and does not contain the location in my sources where the error located. It should have been: kernel32.RaiseException TList.Get+$3c TForm1.Button1Click The main reason i think is that debug info is stripped of from the vcl runtime packages. The reason is obscure to me. The sources for vcl are available but you cannot recompile these packages with debug info as there are no dpk projects included. This lack of debugger support makes applications based on runtime packages be a real pain to debug. This is true since Delphi 2 and it was supposed to be fixed in Delphi 2005. Sometimes the projects are developed in such a way, so there is impossible to be compiled without runtime packages and work. In that cases, this missing functionality is a real Show Stopper, that made my team look for thirdparty tools. These tools rely in TD32 info for getting the full call stack in cases when the IDE debugger fails. Why is Borland not implementing the same functionality?

Description: Steps:[QC Short Description] Allow users to create their own Debug Inspectors for objects [QC Description] Allow Delphi users to add in their own debug inspectors and "register" their debug inspectors into the delphi IDE for a given class or interface. This would allow us to make much more intelligent inspectors to show us the data contained in our classes in a much more intelligent way while debugging. For example, the one that really should ship with Delphi would be a custom inspector for IXMLNode. Instead of showing us default debugging information about IXMLNode, we could have a custom inspector actually show us the data contained by IXMLNode. Looking at the sample code below, we could have a break point on the showmessage line and we could inspect variable lNode. Instead of showing us this: lNode | TXMLNode($A52690) as IXMLNodeAccess the custom inspector would show us something similar to what XMLSpy shows us where we could drill down through the XML DOM and actually see the data contained in the lNode. See the attached screen shots for an example of what this could look like. Maybe for this example, Borland could actually get with the Altova folks to take their XML Spy browser and fold it in as a custom inspector. This is just one example, the real purpose of this request is to allow delphi users the ability to add in their own custom inspectors. procedure TForm4.Button1Click(Sender: TObject);

Note that with varString in V, such an invocation works well, just like in Delphi 2007. So this ruins "string"-based code when migrating in Delphi XE :( I have a suspicion that this could be related to parsing varStrArg parameters in ComObj.DispatchInvoke() and in Variants.pas, as there is no additional processing for varUString there.

In TWebBrowser these three ExecWB procedures are defined (can be autogenerated by importing Microsoft Internet Controls): procedure ExecWB(cmdID: OLECMDID; cmdexecopt: OLECMDEXECOPT); overload; procedure ExecWB(cmdID: OLECMDID; cmdexecopt: OLECMDEXECOPT; var pvaIn: OleVariant); overload; procedure ExecWB(cmdID: OLECMDID; cmdexecopt: OLECMDEXECOPT; var pvaIn: OleVariant; var pvaOut: OleVariant); overload; The implementation of the first one looks like this: procedure TWebBrowser.ExecWB(cmdID: OLECMDID; cmdexecopt: OLECMDEXECOPT); begin DefaultInterface.ExecWB(cmdID, cmdexecopt, EmptyParam, EmptyParam); end; The flaw is that EmptyParam is passed directly as pvaOut. When the call returns, EmptyParam no longer has the special value it was initialized to and therefore no longer is empty. In our case the changed EmptyParam caused a column to be updated in the DB to NULL although a real value was given as a parameter, when using ADO. Other queries failed with strange errors of mismatching types etc. At least any parameter defined as an out (or var) parameter should get a local variable in the function that is initialized to EmptyParam before it's passed on. Another peculiarity is that there are two EmptyParam declared. One in Variants.pas and one in OleCtrl.pas. The one in OleCltr.pas is assigned from the Variants.pas version during initialization, but thereafter lives it's own life. TWebBrowser uses the EmptyParam defined in Variants.pas. QC Entry 61255

How to check that EmptyParam is changed: 1. Start Delphi 2007. 2. Create a new application "File->New->VCL Forms Application - Delphi for Win32". 3. Drop a TWebBrowser on the form in Unit1. 4. Add an OnCreate-event to the form that initializes the web-browser, e.g.: procedure TForm1.FormCreate(Sender: TObject); begin WebBrowser1.Navigate( 'http://www.google.com' ); end; 5. Add a button and in it's OnClick-event put the following: procedure TForm1.Button1Click(Sender: TObject); begin if not VarIsEmptyParam(Variants.EmptyParam) then ShowMessage('EmptyParam initial check failed!'); WebBrowser1.ExecWB(OLECMDID_COPY, 0); if not VarIsEmptyParam(Variants.EmptyParam) then ShowMessage('EmptyParam changed by ExecWB!'); end; 6. Run the program and wait for the web page to load. 7. Press the button. Expected: Code executed without any message shown. Experienced: The message "EmptyParam changed by ExecWB!" is shown, i.e. the EmptyParam is no longer empty!. How to generate the illegal type library code: 1. Start Delphi 2007 2. Select the menu item Component->Import Component... 3. On the first page ("Type of Component") of the "Import Component" window choose "Import Type Library" and press Next. 4. On the "Registered Type Libraries" page select the type library containing Microsoft Internet Controls and click Next. On my 64-bit Vista with IE7 it's named "Microsoft Browser Helpers" and found in the file C:\Windows\SysWOW64\ieframe.dll, but if you have an older IE-installed it might be in SHDocVw.dll. 5. Click Finish to genereate the unit SHDocVw_TLB. 6. Locate the three implementations for TCppWebBrowser.ExecWB: procedure TCppWebBrowser.ExecWB(cmdID: OLECMDID; cmdexecopt: OLECMDEXECOPT); procedure TCppWebBrowser.ExecWB(cmdID: OLECMDID; cmdexecopt: OLECMDEXECOPT; var pvaIn: OleVariant); procedure TCppWebBrowser.ExecWB(cmdID: OLECMDID; cmdexecopt: OLECMDEXECOPT; var pvaIn: OleVariant; var pvaOut: OleVariant); Examine the one taking only two parameters: procedure TCppWebBrowser.ExecWB(cmdID: OLECMDID; cmdexecopt: OLECMDEXECOPT); begin DefaultInterface.ExecWB(cmdID, cmdexecopt, EmptyParam, EmptyParam); end; The procedure calls DefaultInterface.ExecWB and directly sends the global EmptyParam as parameters for the two extra parameters. These are however var- parameters (one is named pvaIn, the other ovaOut), which means that value of EmptyParam might be (and in reality also is) changed, which causes serious problems in other code using COM.

Description: Steps:TAutoIntfObject.InterfaceSupportsErrorInfo compares the passed GUID against DispIID which is read-only, private and NEVER initialized by TAutoIntfObject. As such InterfaceSupportsErrorInfo always returns False which prevents D6 from returning IErrorInfo object back to VC client. This existed in D5 and exists in D7 as well. QC Entry 2670

this is from the QC "workaround" page: As a workaround you must create a complete copy of the TAutoIntfObject class because the FDispIID variable is declare as private. Copy the TAutoIntfObject class declaration and all of the implementing code form ComObj.pas, giving your version of the class an appropriate name. The code below came from D6 Update #2. You should make your copy from your own comobj.pas. In the constructor add the line: FDispIID := DispIntf; TSKAutoIntfObject = class(TInterfacedObject, IDispatch, ISupportErrorInfo) private FDispTypeInfo: ITypeInfo; FDispIntfEntry: PInterfaceEntry; FDispIID: TGUID; protected { IDispatch } function GetIDsOfNames(const IID: TGUID; Names: Pointer; NameCount, LocaleID: Integer; DispIDs: Pointer): HResult; stdcall; function GetTypeInfo(Index, LocaleID: Integer; out TypeInfo): HResult; stdcall; function GetTypeInfoCount(out Count: Integer): HResult; stdcall; function Invoke(DispID: Integer; const IID: TGUID; LocaleID: Integer;Flags: Word; var Params; VarResult, ExcepInfo, ArgErr: Pointer): HResult; stdcall; { ISupportErrorInfo } function InterfaceSupportsErrorInfo(const iid: TIID): HResult; stdcall;public constructor Create(const TypeLib: ITypeLib; const DispIntf: TGUID);{$IFDEF MSWINDOWS} function SafeCallException(ExceptObject: TObject; ExceptAddr: Pointer): HResult; override; {$ENDIF} property DispIntfEntry: PInterfaceEntry read FDispIntfEntry; property DispTypeInfo: ITypeInfo read FDispTypeInfo; property DispIID: TGUID read FDispIID; end; { TSKAutoIntfObject } constructor TSKAutoIntfObject.Create(const TypeLib: ITypeLib; const DispIntf: TGUID); begin inherited Create; OleCheck(TypeLib.GetTypeInfoOfGuid(DispIntf, FDispTypeInfo)); FDispIntfEntry := GetInterfaceEntry(DispIntf); FDispIID := DispIntf; // Fix for QC bug # 2670

Description: Steps:[QC Short Description] TOleControl incorrectly calculates position rectangle, and it's descendants may become invisible [QC Description] Now that's a good bug... TOleControl.SetBounds method incorrectly calculates rectangle for passing it as a parameter to SetObjectRects method of it's ActiveX control IOleInplaceObject interface. This is the code from OleCtrls.pas: if FOleInplaceObject <> nil then begin LRect := Rect(Left, Top, AWidth, AHeight); FOleInplaceObject.SetObjectRects(LRect, LRect); end; But Rect function expects it's two last parameters to be Right and Bottom, not Width and Height! Those, LRect is calculated totally incorrectly. As long as resulting LRect is not empty, control resizes and positions correctly anyway, because in TOleControl.SetBounds it's bounds are corrected later by a call to inherited TWinControl.SetBounds. But if Left >= AWidth, or Top >= AHeight, then resulting LRect is treated as empty, and SetObjectRects can make control's window invisible (at least this is what Web Browser control does), and this is not corrected already. The control disappears from the screen. This problem affects both design and run time. I've found this bug when using TWebBrowser, but it should affect other descendants of TOleControl, too. In Delphi 7, there is no such problem, because there TOleControl.SetBounds didn't contain a call to IOleInplaceObject.SetObjectRects at all. Also, note that in current OleCtrls.pas code, bounds parameters passed to Rect function are a mixture of old ones - Left, Top, and new ones - AWidth, AHeight. This can be a bug, too, yet I'm not sure. Even if the code is corrected (by, say, replacing a call to Rect function with similar call to Bounds function), it still will produce incorrect bounds rectangle when we both resize and move control in one call to SetBounds. So I would also replace Left and Top with ALeft and ATop. QC Entry 45088

1. Create new VCL application, drop a TWebBrowser component on a form and position it so that it's Left > Width, or Top > Height (or both). Move it to the form's right bottom corner, for instance. 2. Now resize TWebBrowser object - decrease it's width or height a little, with mouse or from Object Inspector, doesn't matter. It disappears from the screen! Even when you select it explicitly from Object Browser, you can't see the control anymore.

ComObj.DispatchInvoke() handles varStrArg arguments specially in that it silently converts them back and forth. In Delphi 2010, the argument types are "varOleStr, varOleStr or $80"; as you can see in the disassembly the UnicodeString is passed by value. There's neither a special flag nor special handling for UnicodeString types in ComObj. This could be fixed by adding a new special string type flag for UnicodeString, handling it in ComObj.pas and adjusting the compiler codegen a bit. QC Entry 86712 QC #: Date Reported: Area:

Description: Steps:[QC Short Description] SafeCall function mapping does not work [QC Description] When upgrading a project from Delphi 2007 to Delphi 2009 the generated pas file for the type library does not seem to follow the safecall calling convension. The previous version of Delphi used to generate procedures with safecall and this version generates functions with result of type HResult; stdcall;. SafeCall function mapping is set to "All V-table interfaces" and I've restarted the project(and the Delphi application(IDE)). To generate the safecall code It takes some indeterminate sequence like this: change the option to somehing other than "All V-table interfaces". Restart the IDE. Open Project. Generate _tlb.pas file. Close project. Change option to "All V-table interfaces". Restart Ide. Start project. Generate "_tlb.pas" file. QC Entry 72637

1. Go to Tools->Options->Environment Options->Delphi Options->Type Library and set Set SafeCallfunction mapping to "All v-table interfaces" 2. Restart the IDE 3. Create new Delphi project "ActiveX Library" 4. Create new interface IUnknown 5. Create new method. 6. Save using the default names. 6. Look at the generated "Project1_tlb.pas" file


Description: Steps:[QC Short Description] Type library editor does not accept optional parameters in properties [QC Description] For example this is from the Microsoft Web Components Type Library (similar to the Excel one) for the Interface "Range" function _Default(optionalin Row, Column: OleVariant): OleVariant [propget, dispid $00000000, helpcontext $06006001']; safecall; procedure _Default(optionalin Row, Column: OleVariant; var: OleVariant) [propput, dispid $00000000, helpcontext $06006001']; safecall; The Type Library editor complains about I"Invalid Flag Combination", whilst this is valid. At worst the Editor should ignore but preserve the flags. These flags make it possible to write in VBA: Set R = Range("A1") R = 5 Also if you remove the parameter flags the Editor, accepts the definition, but does recognise the property as "default", despite the dispid being 0. Is this a separate bug?? QC Entry 7725

The Steps to reproduce are as follows. 1) Create a new Type Library 2) Add an Interface 3) Add a Read/Write Property of any type 4) Add two parameters to the property of type OleVariant 5) Set the modifier of these two parameters to optionalin 6) Try to save the type library and the error message about "Invalid Modifiers" flashes at the StatusBar of the Type Library Editor

Description: Steps:[QC Short Description] SafeCall function mapping not honored [QC Description] This issue addresses QC reports 68286 and 72637. Both have been closed, when in reality they have not been fixed. This is now version XE (2011). The last time this really worked was Delphi 2007. COM programmers have been getting headaches with Delphi 2009, 2010, and XE. That's a lot of versions for this functionality to not work when it actually used to. Also, the workarounds suggested in those QC reports don't work for me. In Tools > Options > Environment Options > Delphi Options > Type Library, there is a "SafeCall function mapping" group box. There are three values: All v-table interfaces, Only dual interfaces, and Do not map. The point behind the "All v-table interfaces" options is explained here: Objects in COM implement Interfaces. Those interfaces can declare methods (procedures which don't return anything), functions (which return COM types or other interfaces), and properties (which allow you to get/set COM types or other interfaces). Ideally, when we program with COM objects and interfaces in Delphi, we want the code to look familiar. Therefore, if we set a property on an interface, we expect the property to be on the left side of an assignment operator ( := ). Likewise, if we call an interface function, we have the result of that function being assigned on the left side of an assignment operator. If we want the value of a property, then we just use that property's name in code. That is the purpose of the safecall option above. It declares all members of object interfaces with the safecall function and those members can be used how we expect them with normal Delphi syntax. But Delphi 2009, 2010, and XE seem to ignore the setting. If you import a type library with using Delphi 2007 or earlier (not 8), and that type library declares an IEnvelope interface, it will declare a Get_Width function that returns a Double, a Set_Width procedure that takes a Double, and a Width property that you can get or set with a Double. But these versions of Delphi don't generate _TLB files like that. They will import the same interface with a Get_Width function with an OUT parameter of type Double, and the function itself returns an HRESULT. The Set_Width method is ALSO declared as a function that takes a Double and returns an HRESULT. And the Width property itself, is nowhere to be found. Can you see the difference in resulting coding styles?

With SafeCall mapping successfully used in Delphi: pEnvelope.Width := pEnvelope.Width * 2 Without SafeCall mapping successfully used in Delphi: var dWidth: Double; begin pEnvelope.Get_Width( dWidth ); pEnvelope.Set_Width( dWidth * 2 ); Now, this issue can be overcome somewhat by using the type library importer (tlibimp) with the -Pt switch set to +. But the Type Library Editor doesn't honor this setting. If you create a new object (or like me, load one that was working in 2007) and you Refresh or create new objects that implement interfaces, then the resulting methods in your object are Get_ and Set_ functions that return HRESULTS, despite the setting in the Tools > Options dialog. And this is just bad. I don't like it, and I'll keep using Delphi 2007 for my COM development until this gets good and fixed! Whether or not the QCs on this matter are closed or not, I'll use XE for COM when it's actually fixed. If Embarcadero is intentionally trying to throw me on .NET bandwagon, it won't work. Signed, Disappointed Delphi fan "Roj" So many other things are great about Delphi that I wouldn't switch. But to break something that worked before just makes me whine. Notice that it stopped breaking in the very version of Delphi that introduced the .ridl format. I sincerely don't know if that's a coincidence. QC Entry 88995 QC #: Date Reported: Area:

Description: Steps:I'd like the ability to specify alignment inside blocks of asm code, and I'd like the implementation to mimic the way TASM allows code alignment, that being, via the ALIGN keyword. The BASM already supports DB, DW and DD, as well as some other keywords that have a history with TASM (TYPE returning the size of a specified type, for example), so this seems more logical than using a compiler directive, especially for BASM code. An example of how this might look in the 'Steps'. The place to note the difference is in the line before '@@1:'. The syntax for ALIGN would be-- ALIGN [boundary] Where [boundary] is an optional power of two address boundary (2, 4, 8, etc). If no address boundary is given, then a default is used (perhaps the record field alignment specified in the project options?). If this is implemented, it'd be nice if the EVEN keyword were also implemented (I believe EVEN essentially maps to ALIGN 2). QC Entry 4530

Description: Steps:[QC Short Description] Request for a .ALIGN directive is BASM [QC Description] To write optimized assembler code with BASM, It is very important to have a .ALIGN 16 directive in Delphi, capable to align CODE/DATA on a 16 bytes boundary This is true for both 32 and 64 bits mode, and even mandatory in some case for 64 bits. Quote extracted from Intel® 64 and IA-32 Architectures Optimization Reference Manual " Assembly/Compiler Coding Rule 12. (M impact, H generality) All branch targets should be 16-byte aligned. " This imply the necessity of a .ALIGN directive in BASM See Steps for a sample QC Entry 73745

90984 1/20/2011 Compiler\Delphi\Code Generation/Optimization

Description: Steps:[QC Short Description] Compiler freezes on correct code with some try, except, finally blocks. [QC Description] By USc: Using inline in connection with Exit may cause an endless loop in the compiler. The issue exists at least since D2007, but affects the QC reporter first with DXE, because between D2010 and DXE a call to Exit has been added in SysUtils.DeleteFile. -> see steps QC Entry 90984

Steps by USc: - save the following program - dcc32 QC90984.dpr expected: compilation finish in a few seconds actual: compilation "never" finishs Removing the inline directive or compiling with inline off (dcc32 QC90984.dpr --inline:off) makes it compiling. program QC90984; {$APPTYPE CONSOLE} //Delphi XE's SysUtils.DeleteFile does use Exit on Windows // in contrast to prior versions function DeleteFile(const FileName: string): Boolean; inline; begin Result := False; if not Result then Exit; end; function TransformDatabase(ASource, ADestination: string): Boolean; var Temp: string; begin // some code try Result := False; Temp := 'Tempfile.dat'; // some code try // some code try // some code except Exit; end; finally DeleteFile(Temp); end; Result := True; finally // some code end; end; begin WriteLn('PASS'); // on compile end. Original Steps: 1. Create new Delphi application with one form TForm1. 2. Insert function TransformDatabase into this form. function TForm1.TransformDatabase(ASource, ADestination: string): Boolean; var Temp: string; begin // some code try Result := False; Temp := 'Tempfile.dat'; // some code try // some code try // some code except

on E: Exception do begin // some code Exit; end else raise; end; finally DeleteFile(Temp); end; Result := True; finally // some code end; end; 3. Press F9 and wait. Compiler stops working after few lines of code and Delphi has to be terminated. Compiler is successful, if line with function DeleteFile is commented. The same code can be compiled without any problem in Delphi 2007.

Load the attached program into the IDE. Set a breakpoint on the line that reads "Value := 'Hello';" Run the program until the breakpoint is reached. Launch the CPU view and see that references to the implicit operators are not inlined but rather are calls. program BTS242167; {$APPTYPE CONSOLE} type TIPv4Address = record private Data: Cardinal; public class operator Implicit(const S: AnsiString): TIPv4Address; inline;//<- doesn't really work class operator Implicit(const I: Cardinal): TIPv4Address; inline; procedure FromString(S: AnsiString); property AsInteger: Cardinal read Data write Data; //SetData; end; procedure TIPv4Address.FromString(S: AnsiString); begin end; class operator TIPv4Address.Implicit(const S: AnsiString): TIPv4Address; begin Result.FromString(S); end; class operator TIPv4Address.Implicit(const I: Cardinal): TIPv4Address; begin Result.AsInteger := I; end; procedure Use(var Value); begin end; var Value: TIPv4Address; begin Value := 'Hello'; Value := 42; Use(Value); end.

[QC Short Description] Bug in code optimization QC Entry 91586

This is a strange behaviour in Delphi 2010 that was different in Delphi 7: Example: I have a class 'TestClass'. This TestClass has three public methods: Method a, b and c. Method a uses an external function defined in a.dll. Method b uses an external function defined in b.dll. Method c uses an external function defined in c.dll. Now i create a new project that uses my TestClass, but it only uses Method a. Now the strange thing: Using Delphi 7: I only have to provide a.dll together with my application because Methods b and c are removed due to optimization. Using Delphi 2010: I must provide a.dll, b.dll and c.dll, although Methods b and c are never used. This compiler does not remove the unused methods b and c. I did not find any setting to change this so i suppose this to be a bug.

Description: Steps:[QC Short Description] Allow procedure/function declarations to specify their entry point code alignment [QC Description] This report requests that a new procedure/function directive be added that allows the developer to specify the alignment of the procedure/function. The new directive would be "align", and this directive would accept an integer value following the directive that specifies how to align the procedure/function. For example-- procedure AlignTest(A, B, C: integer); align 32; begin // code end; Would align AlignTest on a 32-byte boundary, while-- procedure AlignTest2(A, B, C: integer); align 512; begin // code end; Would align AlignTest2 on a 512-byte boundary. The value following should conceivably always be a power of 2 (but I do not believe it should be necessary to require this). If a calling convention is specified, this new directive would behave similar to the varargs directive in that no semi-colon would be used to seperate it from the calling convention. E.g. - procedure AlignTest3(A, B, C: integer); cdecl align 64; begin // code end; Would be correct. QC Entry 6610

Install JCL and JVCL component libraries. You may encounter an error with the JCL install while checking HPP headers. If so, disable the HPP file options in the JEDI install. For Fulcrum, the JEDI team had the following svn project, though with the release the normal download may apply now. http://svn.obones.com:443/fulcrum/trunk/ For read access only use this account: Login = Fu1crum Password = Cr055X Unzip the contents of the attached ZIP file to c:\turbu

C:\TURBU\components\PascalScript\PascalScript_Core_D12.dpk C:\TURBU\components\TURBU\sdlframe.dpk C:\TURBU\components\TURBU\turbu_components.dpk Close All files. Load the project group file, "c:\turbu\turbu\turbu.groupproj" into the IDE. In the package, map_default_design.bpl, bring up these source files and set breakpoints in their initialization sections.

See that each breakpoint is encountered as expected. The program will produce an exception at runtime, namely "Project Turbu.exe raised exception class EBadHandle with message 'glTexImage2d(): GLINVALID_ENUM" To see the problem. Remove MessageEdit.pas from the project for "map_default_design.bpl" via the Project Manager. Add "C:\TURBU\turbu\turbu format\design\EB Editors\Messages\MessageEdit.pas" to the project for "default_format_design.bpl" Recompile the project, "turbu.exe", and run. See that the breakpoints for "MessageOptions.pas" and "PortraitEdit.pas" are encountered as expected but not that of "MessageEdit.pas" as occurred when it was part of "map_default_design.bpl". Launch the Modules View and see that "map_default_design.bpl" is present.

Description: Steps:[QC Short Description] Compiler finalizes record incorrectly [QC Description] When you have (a) a record that contains an interface reference and one or more methods, (b) a function that returns that record, and (c) code that chains a call to that function with a call to a method on the record (e.g. MyFunction.DoSomething), the compiler incorrectly finalizes the interface refcount too many times, causing the interfaced object to be freed even though there's still a live reference to it. This results in heap problems and sporadic

Actual: pops up a FastMM error dialog showing that an interface was used after it was freed (see attached screenshot). -------- To repro the problem from scratch: 1. Create a new Win32 console app. Save it somewhere. 2. Download the FastMM4 distribution from http://fastmm.sourceforge.net/. Copy the following files from the FastMM zip into the same directory as your project file: - FastMM4.pas - FastMM4Messages.pas - FastMM4Options.inc - FullDebugMode DLL\Precompiled\FastMM_FullDebugMode.dll 3. Make the following changes to FastMM4Options.inc: - Define FullDebugMode. (remove the "." before the "$define") - Define CatchUseOfFreedInterfaces. (remove the "." before the "$define") 4.

Description: Steps:[QC Short Description] Delphi IDE deadlock during background compiler operation [QC Description] From time to time the Delphi XE Update 1 IDE appears to deadlock with a background compiler operation. The only way I have found to break the deadlock is to delete all DCU files in the project folders. The last time such a deadlock occurred I inspected the BDS.EXE process using Process Monitor: It seems the background compiler gets stuck in a loop opening dcu files associated with the project. Since it looks in the wrong folders most of the time, most of these file open calls fail. However, even after successfully opening a dcu file in the correct folder it does not exit the loop, instead restarting the search from the beginning. I am fairly confident that this is a new problem in XE Update 1, since I do not recall ever experiencing this problem in any prior version. QC Entry 90864

I have not been able to find reproducible steps, but from the recent newsgroup thread in e.p.d.non-technical entitled "Delphi XE hangs with Update 1" it appears that several other users also experience this problem from time to time. new steps... the IMPORTANT thing to NOTE is that the CodeInsight MUST be switched ON to see the problem. 1) Extract the attached archive to the root of the C: drive. 2) Start Delphi XE 3) Copy and paste the library paths in "Delphi XE Library Path.txt" into the library path settings of Delphi XE 4) Open the Project1.dproj in the c:\projects\CIMSO\TestApp1 folder5) Compile it with Ctrl+F9 6) Open the Project1.dproj in the c:\projects\CIMSO\TestApp2 folder7) Compile it with Ctrl+F9 8) Open Unit1.pas (pressing F12 should do the job) and view the source 9) Ctrl+click on PSDForm in the "uses" list to open up PSDForm.pas10) Modify the PSDForm.pas (adding a blank line anywhere will suffice) 11) Select File -> Reopen and select c:\projects\CIMSO\TestApp1\Project1.dproj 12) Delphi will prompt to save PSDForm.pas - Click "yes" 13) Open Unit1.pas and view the source 14) Ctrl+click on PSDForm in the "uses" list to open up PSDForm.pas15) Modify the PSDForm.pas (adding a blank line anywhere will suffice) 16) Select File -> Reopen and select c:\projects\CIMSO\TestApp2\Project1.dproj 17) Delphi will prompt to save PSDForm.pas - Click "yes" The Delphi XE IDE will hang somewhere between steps 13 and 17. If it doesn't happen the first time, repeat steps 13 through 17, alternating between the two test projects. Workaround: Run clean.bat (deleting all dcu files) when it hangs and the IDE will become responsive again. Comment: the dcc150.dll seems to be culprit.

Description: Steps:[QC Short Description] TRttiRecordType should override GetDeclaredFields and not GetFields [QC Description] TRttiType.GetDeclaredFields() is meant to return all fields which are explicitly declared (i.e.: not inherited) for the type in question, whereas TRttiType.GetFields() merely collects and concatenates all ancestor fields. However, for some reason TRttiRecordType overloads GetFields() and not GetDeclaredFields(), which implies that you won't see the record fields if you call GetDeclaredFields(). The fix is trivial: rename TRttiRecordType.GetFields() to TRttiRecordType.GetDeclaredFields(). QC Entry 84627

Description: Steps:[QC Short Description] Winsock.pas needs to be updated to Winsock 2.2 [QC Description] The header, Winsock.pas should be updated for the Winsock 2.2 specifications as well as some additional functions that Microsoft has included in their stack. The Winsock.pas file is still based on Winsock 1.1 which is over 16 years old. Winsock 2.2 was introduced in 1996 and was included in Windows NT 4.0, as an optional addon for WIndows 95, and has been included since then. Winsock 2.2 supports some things that were not included in the Winsock 1.1 specification and supports things such as layered service providers (LSP's), namespaces, IPv6 addresses, and various other stuff. The only way that the Winsock 1.1 spefication file header works is that there's a WInsock 1.1 compatability shim, and you are only using the Winsock 1.1 subset of functions. QC Entry 82588

Description: Steps:[AMP] [QC Short Description] TDictionary.ExtractPair Fails and creates memory leak [QC Description] The documentation is a bit lacking on this function, but it seems reasonable to assume that ExtractPair should reteurn the Key/Value pair for the supplied Key. Calling it with a valid key causes the key/value pair to be hidden from the list, but does not return the values to the user. Furthermore, if the dictionary is a TObjectDictionary set to own the Objects, the reference to the object is lost, but the object is not freed so we get a memory leak. /////////////////////////////////////////////////////// Although the bug was reported only on Vista, it also reproduces on Windows. However, the Fixed configuration does not work on Windows. [AMP] ///////////////////////////////////////////////////// QC Entry 80947 [PulsarBeta]

Download the attached test project and run it. It will report the errors. It has two configurations - Standard and Fixed. In the Fixed configuration the Dictionary is modified to work as I think it should. Incidentally, the fix relies on access to private members of TDictionary which should not work- so i think that is another minor compiler bug.

Description: Steps:[QC Short Description] ObjAuto.ObjectInvoke casts varBoolean to integer [QC Description] When the function ObjAuto.ObjectInvoke attempts to cast the parameter data to the proper data types for the dispatch method being called, it is casting VarTypes of varBoolean to an integer. This occurs when the ConvertKindOf returns ckNone. In the case where the dispatch method being called accepts a variant type, the VarType of the value passed to the parameter is now identified as varInteger. According to the comments in the code it looks as though an intended step is missing: // Convert Boolean/LongBool params to integer via hardcast to Boolean // ensuring that _VarToBool is called to fix a bit clearing issue. The code does not ensure the call to _VarToBool is made: if (VarType = varBoolean) then begin Temps[I] := Integer(Boolean(Params[I])); ParamVarData := @Temps[I]; end; The code is only converting the Boolean to an Integer.

The test application may seem a bit contrived, but it demonstrates a situation where Move fails with a Floating Point exception. It only fails if the X variable has the two values shown in the sample app. For other values of X, we were able to get a Floating Point exception in the FillChar routine.

Description: Steps:[QC Short Description] TThreadedQueue fails with multiple consumers [QC Description] Trying to use the TThreadedQueue (Generics.Collections) in a single producer multiple consumer scheme. The idea is to push objects into a queue and let several worker threads draining the queue. It does not work as expected, though. When two or more worker threads are calling PopItem, access violations are thrown from the TThreadedQueue. If the call to PopItem is serialized with a critical section, all is fine. The problem seems to be related to TMonitor in TThreadedQueue. QC Entry 91246

Description: Steps:[QC Short Description] AV in TInternalConditionVariable.RemoveWaiter [QC Description] When synchronizing two threads using a TConditionVariableCS access violations may occur in the method TInternalConditionVariable.RemoveWaiter in SyncObjs.pas (966): Walker := Walker.Next; where Walker is nil. QC Entry 78415 [top10] Added by Sysop <<<<<<<<<<<<<<< This is a comment from QC ---- I've attached a new project which reliably crashes under Windows versions prior to Vista. ---- Please see 'qc78415.patch' attached. >>>>>>>>>>>>>>>

See attached project archive. (JJS: The attached app doesn't reproduce for me. However, here are Christian's comments from the original QC report.) I have modified the code to call ReadLn at the end but to no avail. The AV occurs only when running the process within the IDE debugger. If I start the process outside the IDE everything runs fine. That's the problem with racing conditions, I suppose. Perhaps the fact that I develop on a Quad Core CPU has an inpact on the runtime behaviour. It seems there is a bug (actually two bugs) in TInternalConditionVariable.RemoveWaiter. Suppose the linked list of waiting threads contains the three entries T1, T2 and T3 which have been added in this order. The linked list looks like this: H -> T3 -> T2 -> T1 -> T3 'H' stands for the pointer to the head of the queue (FWaitQueue field). Bug 1: Removing the second item of the wait queue is not possible. Cause: When removing a thread, the walker pointer actually starts at the third entry (T1 in this case). Iteration stops however as soon as the walker reaches the head of the queue (T3), which leaves T2 undetected. Bug 2: The first item of the queue cannot be removed. Cause: In case the first item is to be removed, just the pointer to the head item is moved without updating the links. Hence the resulting queue looks like this: H -> T1 -> T3 -> T2 -> T1 Furthermore the head points to T1 while it should actually point to T2 since that item followed T3 in the original list. I have attached a patch which can be applied to SyncObjs.pas that

corrects both of these issues. 1. Iteration now starts at the second item (T2) and stops at the first (T3). 2. If the first item is removed, the new list now looks like this: H -> T2 -> T1 -> T2

See Details on how to get numbers smaller than the pretended minimums and larger than the maximums shown above. Of course, there is a gigantic number of other floating point values that fall outside unit Math's Min-Max ranges. My examples just show the most extreme ones, i.e., these are the actual minimums and maximums. Since floating-point constants in Delphi always are Extended, the definitions for Single and Double values need 20 significant digits (not just 6, 14, or 18) in order to get the exact Extended equivalent of the extreme Single and Double values. In a typed constant definition one could do with fewer digits. However, typed constants are no constant expressions to the compiler. QC Entry 36965

Unicode is multibyte encoding. Reader reads some amount of data into byte array. Then it runs loop in which try to convert this bytes to Unicode from UTF8. If it was unsuccessful it suppose that last byte in that array was insufficient to form a character. Than it increases length of array by 1 byte, reads it from file, and tries again (continuing the loop). The problem is that loop may reallocate this buffer array until the file entirely fits into this buffer (1 MB file ~ 1million of SetLength(array, Length(array) + 1) and other API calls).

Even from the comments in the TSOAPAttachment.SOAPToObject() source it's clear that this is an error in the code, however it doesn't lead to a compile-time-error because unfortunately AttachFound as well as Self are of the samte type (TSOAPAttachment). { Transfer ownership } AttachFound.Ownership := soReference; { Make sure SOAP Runtime does not delete this object } DataContext := Nil; obviously the comment in the second-last line means, that the AttachFound should not be destroyed by the runtime, however DataContext := Nil; prevents the current soap-attachment-object from getting freed...

It's invalid to have the message attribute there. [NOTE: Because of this one cannot import the WSDL of a Delphi Service using Axis (Java) WSDL2JAVA utlity).

1. Build any WebService in Delphi 2. Look at the WSDL 3. Go to the '<binding name="xxxx" type="xxxx"> section and look at the <input> node following each operation. You'll see something like this: <binding name="InteropTestPortTypebinding" type="tns:InteropTestPortType"> <soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/> <operation name="echoString"> <soap:operation soapAction="http://soapinterop.org/" style="rpc"/> <input message="tns:echoString0Request"> <<<===== "This is wrong" An example of this can be seen at the following URL: http://hirondelle.inprise.com/WebServices/Interop/cgi-bin/InteropService.exe/wsdl/InteropTestPortType Now, do the same on a Java/AXIS or .NET Service. For example, you can view a .NET service at: http://corbeau.inprise.com/webservices/sample-service.asmx?WSDL=wsdl1 You'll see: <wsdl:binding name="InteropTestPortTypebinding" type="tns:InteropTestPortTypebinding"> <soap:binding transport="http://schemas.xmlsoap.org/soap/http"/> <wsdl:operation name="echoString"> <soap:operation soapAction="http://soapinterop.org/" style="rpc"/> <wsdl:input> <<<<<===== "No 'message' attribute !!

Open any VCL member function in the BCB 2006 help. They are documented without the __fastcall modifier.

For example: <ms-help://borland.bds5/delphivclwin32/Classes_TThread_Execute1.html> Syntax C++ virtual Execute() = 0; should read: [C++] virtual void __fastcall Execute() = 0; Cogswell is actually worse than DeXter, because it omits the "void" part of the declaration as well.


Description: Steps:[QC Short Description] Undocumented Capability of Using TIndexOptions::ixUnique with TClientDataSet::AddIndex [QC Description] The documentation for TClientDataSet::AddIndex states: "Options is a (potentially empty) set that can include up to two TIndexOptions values. The valid members for that set include ixDescending...and ixCaseInsensitive. Warning: AddIndex throws an exception if you attempt to create an index that includes any other TIndexOptions values."

1) Create a TClientDataSet. 2) Activate it. 3) Call its AddIndex method, setting the Options parameter to "TIndexOptions() << ixUnique". 4) Observe that no exception is thrown, and the unique index is enforced. This method of indexing the TClientDataSet, by the way, is handy for catching key violations locally, rather than letting the DB catch them after calling TClientDataSet::ApplyUpdates. The attached project should adequately demonstrate that this does work.

In "Understanding ClientDataSet Indexes" by Cary Jensen on the Borland Community Site (http://community.borland.com/article/0,1410,29056,00.html), it states: "The second [parameter] is the semicolon-separated list of the index fields...Note, however, that only the ixCaseInsensitive, ixDescending, and ixUnique TIndexOptions are valid when you invoke AddIndex. Using any of the other TIndexOptions flags raises an exception. " Indeed, ixUnique *can* be specified for Options without generating an exception, and the TClientDataSet behaves as expected (a key value exception is thrown by the TClientDataSet if a duplicate key value is inserted).

Description: Steps:[QC Short Description] IDE Compiler searching & opening the same file multiple times during compiling [QC Description] This is Technically a duplicate of QC: 13775 but with everything together in a cohesive whole with the reasons why it occurs. Asked for by David Dean. When BDS 10/11 compiles a project the internal compiler re-searches for header (and source) files mulitple times down the entire include path; even though it should know where it found it last time -- this is waisting a lot of time duplicating efforts that it should already know about. All of Code Insight features also uses the internal compiler

Attached is Andreas Plugin with my mod to track the stats per compile 1. Load BDS 110 project, Install plugin 2. Run->Load Process 3. Choose BDS.exe and run 4. Open the WPM sample application located in ($BDS)\Demos\CPP\Apps\Wpm 5. Project -> Options 6. Disable ALL pre-compiled headers (otherwise your numbers are not correct) -> OK 7. Project -> Build WPM 8. Switch to BDS where you are debugging IDE and you should have on your eventlog: File In Known: 308, In Missed: 655, Total: 1174 Date In Cache: 140, Total: 279 8. Switch back to BDS, and click in the source 9. Hit CTRL-Space, to activate one of the Code Insight features. File In Known: 86, In Missed: 294, Total: 591 Date In Cache: 139, Total: 139 Now these numbers grow exponentionally (yes, exponentionally) each additional unit you add to a project, so on this small aplication with one form (two CPP files); you have that many file hits. Please

which then causes CI to be a lot slower than it can be. QC Entry 38921

note the stats/cache are reset for EVERY compile. The statisics are: Number of files that the plugin cached as already knowing didn't exist in that location from a prior request Number of files that the plugin cached as already knowing existed from a prior request Total number of file requests. If you subtract the two cache counts from the Total, that will leave you with the total number of _unique_ valid file requests (Using the above numbers a total of 211). Second stats that is the number of requests for the date/time of a file, and how many were requests for dates that _weren't_ cached. If you subtract the two numbers, then result is the number of date/times that were cached that BDS should already have had since it asked for it before. (Sorry the Output say "In Cache" but it sould actually be "Added to Cache". Using the above build numbers meaning a 140 unique file/date requests and a total of 139 duplicate file date requests.

Description: Steps:[QC Short Description] Header file of unit opens separately from cpp file [QC Description] It is possible for the header file of a unit to become opened separately from its associated cpp and/or dfm files. This can lead to having the header loaded into the code editor in two different tabs. When this happens it is possible to make changes to one tab that are not reflected in the other tab. It's also possible for the IDE to crash when the correctly loaded unit is closed prior to the incorrectly loaded header file. View steps to see how that is accomplished. This is a regression for a bug that used to exist in BCB6. It works fine in CB2009 and was broken in CB2010 and still exists in CBXE. The attached project's .dsk file is already in the state to show the two units open at the same time. QC Entry 87974

g Components Description: Steps: [QC Short Description] IDE crash when rebuilding installed package [QC Description] **NOTE ** This really is a Windows 7 problem but it is not available in the list of platforms in my QC client. My system is Windows 7 Pro 64-bit. I have attempted to recreate this issue on Win2008 Server 64-bit and it never fails. This leads me to my belief that this is a Win7 issue. If a C++Builder personality package is empty or contains any other code in the Register() function aside from RegisterComponents() then the IDE will crash when attempting to rebuild, clean, or uninstall the package. The IDE displays an AV with a stack dump (shown below). If instead of an empty package I register one or

- Launch RSXE (fresh install or otherwise) - Create a new C++Builder package (no coding required) - Install the package - Close and restart RSXE - Rebuild the package exp: The package should be momentarily unloaded from the IDE, rebuilt, and then reloaded into the IDE act: The IDE displays an AV, CPU use

more components then the IDE will not crash. However, if I then add another single line of code to Register() such as Beep(), or __typeinfo(), etc then the IDE crashes again. For me, this problem happens in RS2010 as well. It does not happen in RS2009.

Description: Steps:I can't port existing BCB5 translated applications. AFAICT there are several faults in the resulting BPRs including: UNITNAME is always "Form" CONTAINERID is always empty (though this may be correct). In addition "#pragma resource" has been changed so that you needdouble '\\'s to represent a single '\'. Having fixed these issues I can get the project to Build and Make but I get EResourceNotFound on running and when I try to open the form for viewing/designing I just get taken to the DFM in the edit window. --------- I tried recreating the project from scratch but after running the Resource DLL Wizard the translation project only had the first form listed. Aside from that it appeared to have the same BPR defects as the upgraded BPR. -------- None of the ITE menu items appear in the IDE although it is listed as an available package.

1.Choose a VCL project with several forms. 2.\File\New\ and select Resource DLL Wizard 3.Click to the language selection page and enable a foreign language. 4.Click on to finish and allow the IDE to recompile and create the new project. You will find the new project has only one form (probably the first listed in your original project) and that double clicking the form in the Project Manager only opens the file in the text editor. The pop-up menu has 'View as form' greyed out. If you attempt to compile this project it will fail at a #pragma directive. If you fix this by replacing '\' with '\\' it will compile and link but the resulting DLL fails when you try and run it and is obviously deficient. // ADDITIONAL EXAMPLE OF 'BROKEN ITE' //////////////////////////////////The 'RichEdit' example project shows some aspects of how broken the ITE is. Each international project does at least have two forms but: 1.They're both called "Form" in the Project Manager 2.You can't view/edit them as forms..only as DFMs. FWIW if you build the project it does work but obviously in its current state it would be a PITA to maintain.

When you run the application it writes "3" in the console as TMemoryStream has 3 properties. Now try to remove the comment in front of the line with __delphirtti(TStream). Now when you run the application it writes "1" in the console. The properties Position and Size have disappeared.

Description: Steps:[QC Short Description] OPENARRAY() and ARRAYOFCONST() evaluate arguments twice [QC Description] In order to get the argument count, both OPENARRAY() and ARRAYOFCONST() pass all arguments to a special template class (OpenArrayCount<>). This implies that all arguments passed to OPENARRAY() and ARRAYOFCONST() are evaluated twice. Here's an example: // ----- #include <SysUtils.hpp> #include <cstdio> int main (void) { int i = 0; Format (L"%d", ARRAYOFCONST ((i++))); std::printf (i == 1 ? "PASS" : "FAIL"); } // ----- It's possible to circumvent this by adequate usage of sizeof() (which probably wasn't possible back in the days of C++Builder 1); I've attached a possible fix. QC Entry 86675

- Build (bcc32 -WCV qc86675.cpp) and run the following code: // ----- #include <SysUtils.hpp> #include <cstdio> int main (void) { int i = 0; Format (L"%d", ARRAYOFCONST ((i++))); std::printf (i == 1 ? "PASS" : "FAIL"); } // ----- Exp.: prints "PASS" Act.: prints "FAIL"


Description: Steps:[QC Short Description] AV when a Delphi record containing managed data types is used as a function Result [QC Description] When a Delphi record type containing managed data types, such as interfaces or strings, is used as a return type for a Delphi function, an AV occurs if the function is called in C++. [MORE INFORMATION]

======================================================================This code is a simplified example of the same crash that occurs in QC #77431: ====================================================================== --- RecIntfCrash.pas --- unit RecIntfCrash; interface type TCrashRec = record

As in C++, a Delphi function returning a record receives a hidden parameter with the address of the destination. However, the Delphi function assumes that the destination memory has beeninitialized/cleared. Delphi does this via a call to __InitializeRecord when a record variable is declared. C++ does no initialization/clearing in a statement like this: PasRec r= GetRec(); Instead C++ relies on the fact that the callee will copy [via the copy ctr] the results directly into the hidden address passed [or, with RVO, just construct the return object @ the hidden address]. The Delphi function returning a record instead invokes the _CopyRecord helper to copy the source into the hidden address. This crashes because _CopyRecord attempts to clear the managed fields as they have non-zero values. [WORKAROUND] A possible workaround would be for the C++ side to use this instead: PasRec r; r = GetRec(); QC Entry 77436

Data: IInterface; Str: String; class function Create: TCrashRec; static; end; implementation class function TCrashRec.Create: TCrashRec; begin Result.Data := nil; // AV in _IntfClear() because Data is not initially zero Result.Str := ''; // AV in UStrLAsg() because Str is not initially zero end; end. --- Test.cpp --- #include "RecIntfCrash.hpp" { TCrashRec r = TCrashRec::Create(); // AV because r is not initialized before jumping into Create() } =========================================================== Another example is from the duplicate 272796 RAID: =========================================================== /--------------------------------------------------------------------------- #include <vcl.h> #include <windows.h> #pragma hdrstop #include <tchar.h> #include <Rtti.hpp> //--------------------------------------------------------------------------- #pragma argsused WINAPI _tWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow) { TRttiContext ctx = TRttiContext::Create(); // <- AV ctx.Free(); return 0; } //--------------------------------------------------------------------------- =========================================================== Another example is from the duplicate 272770 RAID: =========================================================== TValue::_op_Implicit(5);

Description: Steps:[QC Short Description] Variant assignment operators have several flaws [QC Description] There is a number of problems with the assignment operators in the EMUVCL Variant classes: - they are not exception-safe, i.e. the data in the object being assigned to is lost if the assigment fails - they do not check for self-assignment, which means that self-assignment results in data loss - they duplicate all the code in the constructor overloads. And sure enough, there are several cases where the assignment operator and the copy constructor are misaligned. - the Variant classes usually don't check the result of the ::VariantCopy() and ::VariantChangeType() My proposition is to solve all these problems at once by introducing swap() methods and use the "copy & swap" idiom to implement the assignment operator overloads. The attachment contains a test case for the second problem (self-assignment) and a set of patches for sysvari.h, utilcls.h and variant.cpp which address all of the problems listed above. The self-assignment problem has also been mentioned in QC #93966. QC Entry 93971

- Download the attached sample project, compile it (bcc32 -WCV qc76879.cpp) and run it. Expected output: // ----- Testing TObject...

[QC Description] The type info structures in TypInfo.pas have been updated to support the new RTTI features, primarily attributes. Look at the following diff of TTypeData from Tiburon to Weaver: // ----- TTypeData = packed record case TTypeKind of ... tkClass: ( ClassType: TClass; // most data for instance types is in VMT offsetsParentInfo: PPTypeInfo; PropCount: SmallInt; // total properties inc. ancestors UnitName: ShortStringBase; - {PropData: TPropData}); + {PropData: TPropData; + PropDataEx: TPropDataEx; + ClassAttrData: TAttrData;}); ... end; // ----- However, BCC doesn't emit the new type info fields, primarily the PropDataEx and ClassAttrData fields. It is understandable that BCC doesn't fully support the new RTTI features such as attributes right now, but it should at least zero out the new fields - right now the type info generated by BCC is simply wrong, and all code that tries to read in all type info fields simply crashes. To demonstrate the failure, I've attached a test case that simply reads out and skips above fields. It works fine for DCC-built type info but, as expected, it runs into AVs when consuming BCC-generated type info. In addition, once QC's #76875 and #76877 are fixed, I think Rtti.pas will form another good test case for this problem. QC Entry 76879

Description: Steps:[QC Short Description] Use of boost::shared_ptr breaks exception unwinding in constructors [QC Description] boost::shared_ptr provides one useful way of hiding a class's implementation. The header file for the class can be something like #include <boost/shared_ptr.hpp> class X { public: X(); private: struct Impl; boost::shared_ptr<Impl> impl; }; By using boost::shared_ptr, the Impl structure does not need to be defined in the header file. However, in C++Builder XE, an exception thrown in the constructor of X will result in an exception unwinding assertion, and program termination. This did not occur in C++ Builder 2010. QC Entry 89260

The attached project files demonstrate the problem. The main function (test.cpp) is int _tmain(int argc, _TCHAR* argv[]) { try { X x; x.f(); } catch (const std::exception& e) { std::cout << e.what() << std::endl; } return 0; } The class X is defined in the header (x.h) as follows: class X { public: X(); ~X(); void f(); private: struct Impl; boost::shared_ptr<Impl> impl; }; The implementation is in x.cpp: struct X::Impl { Impl(); ~Impl(); }; X::Impl::Impl() { std::cout << "X::Impl ctor\n"; } X::Impl::~Impl() { std::cout << "X::Impl dtor\n"; } X::X() : impl(new Impl()) { std::cout << "X ctor\n"; throw std::runtime_error("could not construct X"); } X::~X() { std::cout << "X dtor\n"; } void X::f() { std::cout << "X::f\n"; throw std::runtime_error("problem in X::f"); } Building and running this program with C++Builder 2010 generates the (correct) output: > X::Impl ctor > X ctor > X::Impl dtor > could not construct X But with C++Builder XE the output is: > X::Impl ctor > X ctor > Assertion failed: varType->tpClass.tpcDtorAddr, file xx.cpp, line 3285 > Abnormal program termination Some other points: 1. If all the code is placed in a single file (e.g. test.cpp), the assertion disappears. (But, of course, this is not very useful for hiding the implementation!) 2. If the exception is not thrown in the constructor, but in some other member function, there is no problem. This can be demonstrated by commenting out the constructor exception throw in the example. 3. The same exception unwinding assertion is raised if the Impl class is left totally undefined, and the X constructor is changed to X::X() { std::cout << "X ctor\n"; throw std::runtime_error("could not construct X"); } Once again, this causes no such problem in C++Builder 2010.

Description: Steps:[QC Short Description] Stack unwinding results in a non-constructed base class's destructor being called [QC Description] An exception thrown by a parameter to a base class's constructor may result in the base class's destructor being called, even though the base class has not been constructed.

1. Build the attached source file. 2. Run it with a nonexistent directory as its command-line parameter. 3. Note that it throws a boost::filesystem exception (as expected) then crashes with an access violation while trying to unwind the stack from the boost::filesystem exception. The debugger indicates that the exception is within boost::filter_iterator's DosWildcardMatcher's mRegex, even though boost::filter_iterator has not been constructed.

The originator claims that clicking repeatedly on the button (i.e., continuously executing the handler) crashed his test program. Couldn't replicate that behaviour.

Description: Steps:[QC Short Description] DCC32 throws exception, fails when building Delphi package to output C++ headers [QC Description] Running RAD Studio XE with both Delphi & C++ personalities on Win7/64-bit. Tried to build SMcomponents (scalabium.com) with "Generate all C++ Builder files" enabled. IDE reports failure in DCC. Manual execution of the DCC32 command line results in the following error after several (apparently) successful compliations: SMBar.pas(1) Fatal: F2084 Internal Error: GPFC00000FD-00463350-0 Modifying the C/C++ output to any option that DOES NOT create header files results in success; any time header files are elected, the error is thrown QC Entry 93439

See comments. Simplified test case attached. 1) Unzip SMcomponents attached to RAID 2) Open RAD studio with both personalities enabled 3) Open SMCmpntXE.dpk in the SOURCES directory for SMcomponents 4) Modify the "BASE" build configuration's "Output-C/C++" config to "Generate all C++Builder files" 5) Build SMCmpntXE.bpl --> dcc error is thrown <-- The dcc GPF error only occurs if C++ headers are emitted. Another interesting item: Change back to generate DCUs only, and the IDE compiler for error insite seems to be having problems with SMBar.pas as well. Starting on line 110, most of the inherited properties being declared in the published section have red squiggles and the Structure pane shows them as "Undefined property". A Syntax check fails, yet a full compile succeeds and produces a valid BPL. This might have something to do with the C++ header generation failing.

92477 3/22/2011 Compiler\Delphi\Header Generation

Description: Steps:[QC Short Description] DCC doesn't emit underlying enum types [QC Description] Forward declaration for enums generated by the delphi compiler is not currently possible because it's underlying type is missing. This could have been implemented since D2009, because of it's partial support for C++0x (which brought that feature into the C++ realm). Currently it's still not possible to forward declare some enums from the VCL like TFieldType, TFieldKind, TLocateOption because auto generated hpp's do not propagate their underlying type as in: enum TFieldType : BYTE { ftUnknown, (...), ftSingle }; enum TFieldKind : BYTE { fkData, fkCalculated, fkLookup, fkInternalCalc, fkAggregate }; enum TLocateOption : BYTE { loCaseInsensitive, loPartialKey }; This really would open the way to have extremely clean and lean headers (and way faster compilations). More information in https://forums.embarcadero.com/thread.jspa?messageID=324731#324731QC Entry 92477

To bypass inclusion of Db.hpp on a header, try to use namespace Db { // #include <DB.hpp> enum TLocateOption : BYTE; } using Db::TLocateOption; it won't compile (type mismatch?). There is no way on the C++ specs to forward declare an enum it we do not specify it's underlying type.

QC #: Date Reported: Area:84198 4/28/2010 Compiler\Delphi\Header Generation

Description: Steps:[QC Short Description] bcc32 -tCV 276923.cpp

Improve support for Delphi records in C++ [QC Description] - Delphi doesn't have the notion of a "default constructor"; for records, the default is to initialize all managed fields to 0 (which is done via RTTI). Unfortunately this means that the compiler won't generate a default constructor for records in C++ header files, whichis problematic especially when the record defines constructors with arguments. TValue takes it to the extreme: it only has a private constructor. Right now there's no clean way to instantiate TValue in C++ code. Suggestion: Have DCC generate a public default constructor for every record. It's as simple as this: // ----- __fastcall [!RecordName] (void) {} // ----- - Delphi supports operator overloads for records, but the aren't beingmapped to C++ operator overloads. For example, look at TTimeSpan in Timespan.hpp and TValue in Rtti.hpp: // ----- struct TValue { ... static TValue __fastcall _op_Implicit(int Value); ... }; ... struct TTimeSpan { ... static TTimeSpan __fastcall _op_Addition(const TTimeSpan &Left, const TTimeSpan &Right); ... static bool __fastcall _op_Equality(const TTimeSpan &Left, const TTimeSpan &Right); ... static TTimeSpan __fastcall _op_UnaryNegation( const TTimeSpan &Value); ... }; Suggestion: if the definitions are public, emit the following additional definitions in the header: // ----- struct TValue { ... TValue (int Value) { *this = _op_Implicit (Value); } ... }; ... struct TTimeSpan { ... TTimeSpan operator - (const TTimeSpan& Value) { return _op_UnaryNegation (Value); } }; TTimeSpan operator + (const TTimeSpan& Left, const TTimeSpan& Right) { return TTimeSpan::_op_Addition (Left, Right); } TTimeSpan operator == (const TTimeSpan& Left, const TTimeSpan& Right) { return TTimeSpan::_op_Equality (Left, Right); } // ----- QC Entry 84198

QC #: Date Reported: Area:1403 12/26/1999 RTL\C++\Threads

Description: Steps:Memory leak due to the different threading models used in the VCL and the RTL. This can cause *massive* leakage if a C RTL function is called that caches thread-specific data. Example: strtok (_tcstok) in STRTOK.C has the line #ifdef _MT save = (_TCHAR **)&_thread_data()->thread_token; #else This will allocate some "static" thread data via "_thread_data_new" (see THRDDATA.C). The problem now is that as part of the VCL threading code (TThread in Classes.pas and BeginThread, EndThread in System.pas) there is no call to either of _endthread, _endthreadex, or _unadopt_thread. And that will cause leakage of sizeof(THREAD_DATA) bytes (see _THREAD.H) each time a VCL thread calling in .Execute any C function that uses this "static" thread data is created + destroyed, because the "static" thread data allocated implicitly via the call to _thread_data will never be freed. This obviously is not limited to TThread, but also System::BeginThread and System::EndThread.

bcc32 -tCV -tM 77393.cpp 77393.exe bcc32 -tCV -tM -DBUG 77393.cpp 77393.exe use task manager to view memory usage (You should see memory increasing while running until the process ends). Note increase in memory usage not observed when _beginthread is used.

I suspect that the best fix is to provide a transition layer for System::BeginThread and System::EndThread for C++ code that unadopts the thread so that the "static" thread data managed by the CRTL is freed. QC: 1403 QC #: Date Reported: Area:88561 10/1/2010 SOAP\Server Applications
