* Avoid a strict aliasing issue in LazyInstance.craig.schlenter@chromium.org2010-03-121-15/+21
| | | | | | | | | | | | The key change here is to use the return value from placement new rather than casting buf_. Avoiding the cast avoids the strict aliasing issue. BUG=28749 Review URL: http://codereview.chromium.org/548011 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@41434 0039d316-1c4b-4281-b951-d872f2087c98
* Isolate tests by running AtExit callbacks between them.phajdan.jr@chromium.org2009-11-191-0/+4
| | | | | | | | | | | | | | | | | | | | For now, this is only for base_unittests. The plan is to enable it for all unit tests. This should finally fix mysterious problems cause by Singletons surviving after one test etc. This change also adapts LazyInstance so that it can be reused after being destroyed. It is used very frequently, for example each time a MessageLoop is used. It is also worth noting that we had some problems in the past related to the MessageLoop being destroyed and re-instantiated in the same test executable. This patch should also fix that.

| | | | | | | | | | | | | | Added annotations for atomic reference counting, LazyInstance and Singleton classes. This changelist is a part of an effort of adding ThreadSanitizer support for Chromium.

creating an instance of an object on first access. This is like Singleton, but without the Singleton property of sharing instances. This also preallocates space for the object to avoid the heap to try to help fragmentation and creation performance.
