           Summary: apr_atomic problems
           Product: APR
           Version: HEAD
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: APR
        AssignedTo: bugs@apr.apache.org
        ReportedBy: davi@apache.org


Following some discussions [1] on the list regarding the apr_atomic
implementation, this patchset tries to address some of the problems
by reorganizing the various backends.

Almost all points raised in [1] are addressed, in special, the unsafe
mixing of mutex and asm (direct) backed atomics. For example, the
apr_atomic_casptr function which was only mutex backed and is used
by the worker and event mpms in httpd.

The patchs still needs more wide testing, but any comments or feedback
would be greatly appreciated.
