* added support to save/restore rsyslog core action settings...Rainer Gerhards2010-07-231-5/+0
| | | | | ... but not those of plugins (which are at least as important as the core ones). So this is an interim commit.
* moving towards scoping inside rsyslog.confRainer Gerhards2010-07-213-77/+77
| | | | first step: adding object-type specifier to config statement table
* fixed a couple of regressionsRainer Gerhards2010-06-234-4/+0
| | | | | | | | by implementing some code that was missing so far ;) as well as finding some real bugs. I also did some general cleanup, removing debug strings and such. This code should be fairly OK to use, except when "exec only when previous action was suspended" is used -- this is NOT yet re-implemented in the tuned engine.
* milestone(BUGGY): batch now pushed down to actionRainer Gerhards2010-06-151-12/+1
| | | | | | | at least in important cases (not for non-direct action queues and some other minor things). This version is definitely buggy, but may be tried with success on a non-production system. I will continue to work on the correctness, but needed to commit now to get a baseline.
* milestone commit(BUGGY): batch is now handed down to rule processingRainer Gerhards2010-06-101-9/+17
| | | | | | | | Now, the full batch is passed down to the rule, which then enqueues the elements as single messages. Note that this code has some known defects and needs more changes until it is correct again. This is primarily a commit to be able to return to a known-(somewhat)-good state.
* some cleanupRainer Gerhards2010-06-101-1/+0

| * main msg q consumer now preprocesses messages before doing rule processingRainer Gerhards2010-06-091-25/+47
| | | | | | | | | | | | | | things like ACL check and message parsing. This leads to a greater level of concurrent processing. Beware, though, that this commit duplicates some messages. May be a regression from this or an earlier commit. I will soon sort out.
| * somewhat improved direct mode queue performanceRainer Gerhards2010-06-091-1/+1
| | | | | | | | | | ... but only for batch enqueues. This will not help much with the current code, but will play well with upcoming changes.
* | fixing msg duplication & loss regression, causes slowdownRainer Gerhards2010-06-101-1/+1
|/ | | | | | | | messages could get lost or be duplicated due to non-proper sync of transactions. This is a notable slowdown again, but we know how to get back concurrency, it just takes "some" more programming. It is important now to come back to correct code, so that we can base further improvements on that.
* bugfix: regression caused more locking action in msg.c than necessaryRainer Gerhards2010-06-081-29/+7

* finshed implementation of strgen modulesRainer Gerhards2010-06-049-81/+574
| | | | | | and also provided four build-in modules for the most common use cases, hopefully resulting in a speedup of around 5% for typical rsyslog processing.
* first implementation of strgen interfaceRainer Gerhards2010-06-014-0/+191
| | | | | and a first built-in strgen module. Some tweaks and more default strgens are needed, but the code doesn't look too bad ;)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Further testing turned out that the rsyslog core works correctly and this fix is not needed. The concurrency we saw was actually caused by other actions (even processes) during directory creation. See commit 9e5b31fc44136dbcc1e443cfe7714e9daf97d844 for further details.
| | * | | | | bugfix: potential segfault in dynafile cacheRainer Gerhards2010-03-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This bug was triggered by an open failure. The the cache was full and a new entry needed to be placed inside it, a victim for eviction was selected. That victim was freed, then the open of the new file tried. If the open failed, the victim entry was still freed, and the function exited. However, on next invocation and cache search, the victim entry was used as if it were populated, most probably resulting in a segfault.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old code looks a bit "strange", though not necessarily incorrect. The new code looks correct and is probably less irritating during bug hunting.
| | * | | | | bugfix: potential re-use of free()ed file stream object in omfileRainer Gerhards2010-03-231-7/+21
| | | |/ / / | | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | when dynaCache is enabled, the cache is full, a new entry needs to be allocated, thus the LRU discarded, then a new entry is opend and that fails. In that case, it looks like the discarded stream may be reused improperly (based on code analysis, test case and confirmation pending)
| | * | | | previous (experimental) patch was somewhat incorrect, fixedRainer Gerhards2010-03-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | This is what caused the new test to fail...
| | * | | | exp: made omfile ensure that it is not called twice in parallel on the same ↵Rainer Gerhards2010-03-211-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | file instance In theory, the rsyslog core should never call in parallel into an output module for the same instance. However, it looks like this seems to happen under (strange?) circumstances. I have now enhanced omfile so that it guards itself against being called in parallel on the same instance data. This is done to help troubleshooting and may stay as an interim solution if it proves to solve an anomaly we see in at least one installation (to trigger this problem, an extremely large traffic volume is needed).
| | * | | | fixed regression from previos (yet unrelease) $omfileFlushOnTXEnd fixtemp.4.6.1.10Rainer Gerhards2010-03-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous fix fixed an issue with on/off bying used in the exact wrong semantic. It corrected the situation, but failed to fix one spot where the wrong semantics were used. This is done with this commit. Note that this is NOT a bug seen in any released version.
