== Why should everybody (including you) test the release candidate? ==

In the past weeks the Lazarus team has stabilized the 2.2 fixes branch. The resulting 2.2RC2 is now stable enough to be used by anyone for test purposes.

However many of the fixes and new features that were committed since the release of 2.0 required changes to the code of existing features too. While we have tested those ourselves, there may still be problems that only occur with very specific configurations or one project in a million.

Yes, it may be that you are the only person with a project, that will not work in the new IDE. So if you do not test, we cannot fix it.

Please do not wait for the final release, in order to test. It may be too late. Once the release is out we will have to be more selective about which fixes can be merged for further 2.2.x releases. So it may be, that we cannot merge the fix you require. And then you will miss out on all the new features.

== How to test ==

Download and install the 2.2 RC2.
- On Windows you can install as a 2ndary install, that will not affect your current install:
http://wiki.lazarus.freepascal.org/Multiple_Lazarus#Installation_of_multiple_Lazarus
- On other platforms, if you install to a new location you need to use --primary-config-path

In either case you should make backups. (including your primary config)

Open your project in the current Lazarus (2.0.x), and use "Publish Project" from the project menu. This creates a clean copy of your project.

You can then open that copy in the RC2. Please test:
- If you can edit forms in the designer
- rename components / change properties in Object inspector / Add new events
- Add components to form / Move components on form
- Frames, if you use them
- If you can navigate the source code (e.g. jump to implementation)
- Auto completion in source code
- Compile, debug and run
- Anything else you use in your daily work

Neat. I did a bit of testing with some of my projects and everything that worked in the last stable version i had (2.0.6) seems to work fine with 2.2.0RC2.

I also did some testing with the MDI functionality that was implemented in Win32 last year, which BTW...

Here is the list of changes for Lazarus and Free Pascal: http://wiki.lazarus.freepascal.org/Lazarus_2.2.0_release_notes http://wiki.lazarus.freepascal.org/User_Changes_3.2.2

...isn't mentioned in the Lazarus changelog (the first non-trunk version to have it was 2.2.0RC1, at least from a quick look in the source code of 2.2.0RC1 and 2.0.12).

The MDI stuff seem to work mostly fine, however there is an issue i noticed with paint and form resize events. I used this doodle app (perhaps i can modify it and have it part of Lazarus tests or something to test MDI support in other widgetsets?):

http://runtimeterror.com/pages/badsector/nyan/gimme/mdidoodlesrc.zip

This builds with Delphi 2 (which is the only Delphi i have access to and what i used as the behavioral basis for my Win32 MDI patch) and Lazarus (make sure to clean everything between builds).

The difference is between Delphi 2, an older SVN-based build of Lazarus i have (Lazarus 2.1.0 r64351M FPC 3.3.1 x86_64-win64-win32/win64) and 2.2.0RC2:

In Delphi 2 the program receives only a single resize event in the MDI child form for the final form size (notice how the both the main form and the MDI child form use the default size which lets windows place it as it wants) followed by a paint event. The app uses a bitmap to store the doodle which is setup during resize events and is drawn on the form itself during paint events.

In r63451M the program receives two resize events, one for some initial (stored during design time, i think) size followed by the larger (due to my large monitor) form size that is shown when it is in MDI - both are fine as long as the final size event is correct, IMO, so no problem here. Then a paint event follows.

In 2.2.0RC2 however the paint event comes between the initial and second resize events which means that the background bitmap is not set up properly.

Now of course it'd be trivial to work around the change by adding an Invalidate call to the resize event, but IMO this is a regression. There should either be a second paint event or the paint event should be delayed until sizing is settled. This would be both consistent with how size and paint events seemed to work in previous version of Lazarus as well as Delphi and also consistent with how Windows (from where most of the VCL and LCL behavior comes from) behaves with WM_SIZE and WM_PAINT (WM_SIZE always comes before WM_PAINT and WM_PAINT is always sent if a window is enlarged to paint the new area).

Beyond the above i couldn't find any other issues with 2.2.0RC2.

Mattias, this should be announced in the forum, too. There are many people who don't read the mailing list.

The checksums page does not have any checksum for 2_2_0RC2. The last update on that page is for 2_2_0RC1.

Are there any plans to publish PGP/GPG signatures of releases?

Cheers,
Noel.
