Summary0011690: Xcode project generator always overwrites user settings
DescriptionWhen generating an Xcode project using CMake, it will completely remove "<project name>.xcodeproj" before generating a new one. The problem with this is that "<project name>.xcodeproj" is actually a folder, not a file.

Contained within this folder you will find the following:
project.pbxproj <-- The actual Xcode project information
<username>.pbxuser <-- Your user data for this project
<username>.mode1v3 (or something similar) <-- Your layout data for this project

When generating an Xcode project, it should *only* generate a new "<project name>.xcodeproj" *if* one doesn't already exist. If one does already exist, it *only* needs to change the pbxproj file inside to update the Xcode project. This will allow CMake to be run without constantly losing your user settings which is *very* annoying when you're working on a project with multiple executables as it keeps forgetting which one you had selected!
Steps To ReproduceCreate an Xcode project using CMake
Change some user settings (such as the build target)
Regenerate the Xcode project and reload it in Xcode
Your changes will be lost

Oops, I'm actually using OS X 10.6.5, not what it says on the bug. I'm also using Xcode 3.2.5, just in case it matters.

It actually correctly keeps the folder and such, the issue is that it randomizes the GUIDs. See comments here: http://www.cmake.org/pipermail/cmake/2010-December/041555.html [^] and http://public.kitware.com/pipermail/cmake-developers/2010-December/000959.html. [^]

I'm working on a patch that follows bills advice.

Attached a patch. I tried to keep the patch to a minimum, since I know other people are doing larger works against the xcode generator. It seems when doing modifications to the cache in the xcode generator, it wasn't automatically written out, so I added a saveCache() call. I'm not sure if this is the correct way of doing things.

There is also the cmGlobalGenerator::createGUID + getGUID() calls. I could not figure out how to properly use these, or their relation to the xcode object files, so I did not use it.

Thanks for the patch. I'll take a look at it sometime in the next week or so and let you know what I think.

ignore the patch for now, seems I broke quite a few of the tests.

0001-xcode-Remember-generated-objectIDs-in-the-CMakeCache.patch is the fixed patch. I had a misstake where objectIDs would be duplicated if the PROJECT name was the same as one of the targets. It now passes all cmake tests on my machine.

and after using it for a bit, this is still broken. The chances of collisions are quite high because it generates IDs based of the heap-location of the objects. Will fix and post updated patch asap.

New version that asserts for duplicate object IDs and uses CoreFoundation to generate real UUID's instead of using the address of the created object.

Fix not ready and stable on time for release in 2.8.5, unsetting target version field...

I haven't tried the patch, but very much agree this would be nice to fix. The described bug is very annoying.

Another specific problem is if one use svn, then there's also a .svn folder in the .xcodeproj folder, and it's presumably blown away too, which confuses svn to no end (happily svn 1.7 will have only one .svn folder at the root).
