* 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.
* new feature: "." action type added to support writing files to relative pathesRainer Gerhards2010-03-171-1/+2
| | | | (this is primarily meant as a debug aid)
* bugfix: recent patch to fix small memory leak could cause invalid free.Rainer Gerhards2010-03-161-2/+2
| | | | This could only happen during config file parsing.
* testbench: new calling interface for tcpfloodRainer Gerhards2010-03-101-0/+7
| | | | | this is a perquisite to support more flexible testing modes, which could not intelligently be implemented with the old interface
* bugfix: potential problem (loop, abort) when file write error occuredRainer Gerhards2010-03-091-2/+2
| | | | | | | | | | When a write error occured in stream.c, variable iWritten had the error code but this was handled as if it were the actual number of bytes written. That was used in pointer arithmetic later on, and thus could lead to all sorts of problems. However, this could only happen if the error was EINTR or the file in question was a tty. All other cases were handled properly. Now, iWritten is reset to zero in such cases, resulting in proper retries.

* Fix Large File Support (LFS) support (bug #182)Yann Droneaud2010-03-041-1/+1
| | | | | | | | | - _FILE_OFFSET_BITS must be defined before including any other system headers otherwise it does nothing. - Don't define it in rsyslog.h, let it be defined in config.h, and let ./configure script enable LFS since Autoconf provides a portable macro to enable LFS support : AC_SYS_LARGEFILE
* Includes "config.h" before any other header.Yann Droneaud2010-03-043-0/+3
| | | | | | | For consistency, ./configure generated "config.h" must be the first header include through out the project. Signed-off-by: Rainer Gerhards <rgerhards@adiscon.com>
* bugfix: potential (but very impropable) segfaults in omfileRainer Gerhards2010-03-021-2/+14
| | | | | | | | | | | | - bugfix: potential segfault in omfile when a dynafile open failed In that case, a partial cache entry was written, and some internal pointers (iCurrElt) not correctly updated. In the next iteration, that could lead to a segfault, especially if iCurrElt then points to the then-partial record. Not very likely, but could happen in practice. - bugfix (theoretical): potential segfault in omfile under low memory condition. This is only a theoretical bug, because it would only happen when strdup() fails to allocate memory - which is highly unlikely and will probably lead to all other sorts of errors.

* fixed typo that (could have) caused compilation fail under FreeBSDRainer Gerhards2010-03-011-3/+3

* make $ActonFileDefaultTemplate available to ompipeRainer Gerhards2010-03-013-15/+17
| | | | | | | | | This was not honored by the new ompipe module, because it is a local file directive (it was applied to pipes as a side-effect of using the same module for pipes and files...). I now made this a global, so that semantics are the same as previously. Not really nice, but probably the best thing to do in the current situation (everything else would involve much more overhead --- leave that for the new config system).

| | | | | | | ... based on old omfile. Michael Biebl reported that xconsole seems to have some issues with the new pipe code, so it was best to use the old code for pipes. The optimizations were done to speed up file access, so it doesn't really matter pipes do not receive them.
* message parser fixes and testbench enhancementsRainer Gerhards2010-02-221-4/+12
| | | | | | | | | - improved testbench to contain samples for totally malformed messages which miss parts of the message content - bugfix: some malformed messages could lead to a missing LF inside files or some other missing parts of the template content. - bugfix: if a message ended immediately with a hostname, the hostname was mistakenly interpreted as TAG, and localhost be used as hostname
* bugfix: message without MSG part could case a segfaultRainer Gerhards2010-02-221-4/+2
| | | | | | | [backported from v5 commit 98d1ed504ec001728955a5bcd7916f64cd85f39f] This actually was a "recent" regression, but I did not realize that it was introduced by the performance optimization in v4-devel. Shame on me for having two devel versions at the same time...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This resulted in wrong values. The most prominent victim was the directory creation mode, which was set to zero in some cases. For details, see related blog post: http://blog.gerhards.net/2009/10/another-note-on-hard-to-find-bugs.html This replaces the improper bugfix from two commits ago with a proper one.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | one-time write to the mode, then all works. However, if no such write is done, the variable always remains zero. I have used the memory debugger as well as shuffled the code around and used guard variables nothing changed. The problem always moved with the changes I did. So I now consider the one-time write a usable work-around, because it definitely fixes the issue even though it does not explain why it happens.
