* added missing support for systems without atomic instructionsRainer Gerhards2010-06-241-0/+15
|
* added support for high-performance action queue submission if not all mark ↵Rainer Gerhards2010-06-081-1/+1
| | | | | | | | | | messages should be logged this was previously not properly handeld. This is also the first occurence of a (real) CAS loop inside rsyslog. Note that the performance is now very well in the default configuration, and mark message directives are still correctly being handled. So this code looks close to final, but needs to have some bug cleanup as the testsuite shows.
* bugfix: regression caused more locking action in msg.c than necessaryRainer Gerhards2010-06-081-2/+11

| * bugfix: problems with atomic operations emulationRainer Gerhards2010-04-271-129/+71
| | | | | | | | | | | | replaced atomic operation emulation with new code. The previous code seemed to have some issue and also limited concurrency severely. The whole atomic operation emulation has been rewritten.

| | * enabled compilation by using "racy" replacements for atomic instructionsRainer Gerhards2010-03-051-0/+3
| | | | | | | | | | | | | | | | | | ... but this is not considered a real solution. For some of the uses, it may acutally be sufficient, but the implications need to be analyzed in detail.

* | moved bParseHostname and bIsParsed to msgFlagsRainer Gerhards2008-10-091-0/+2
|/ | | | | | This enables us to use more efficient calling conventions and also helps us keep the on-disk structure of a msg object more consistent in future releases.
* bugfix: proper synchronization on message destructionRainer Gerhards2008-09-191-0/+1
| | | | | The code was potentially race, at least on systems where a memory barrier was needed. Fix not fully tested yet.
* bugfix: potential race condition when adding messages to queueRainer Gerhards2008-09-181-2/+6
| | | | | | | There was a wrong order of mutex lock operations. It is hard to believe that really caused problems, but in theory it could and with threading we often see that theory becomes practice if something is only used long enough on a fast enough machine with enough CPUs ;)
* re-enabled gcc builtin atomic operations and added a proper ./configure checkRainer Gerhards2008-09-181-9/+9

* moved files to the runtimeRainer Gerhards2008-04-161-0/+51
there are still some files left which could go into the runtime, but I think we will delete most of them once we are done with the full modularization.
