| * | bugfix: repeated messages were incorrectly processedRainer Gerhards2009-09-101-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | this could lead to loss of the repeated message content. As a side- effect, it could probably also be possible that some segfault occurs (quite unlikely). The root cause was that some counters introduced during the malloc optimizations were not properly duplicated in MsgDup(). Note that repeated message processing is not enabled by default.

| | * bugfix: reverse lookup reduction logic in imudp do DNS queries too oftenRainer Gerhards2009-09-032-1/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | A comparison was done between the current and the former source address. However, this was done on the full sockaddr_storage structure and not on the host address only. This has now been changed for IPv4 and IPv6. The end result of this bug could be a higher UDP message loss rate than necessary (note that UDP message loss can not totally be avoided due to the UDP spec)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - control character DEL was not properly escaped - NUL and LF characters were not properly stripped if no control character replacement was to be done - NUL characters in the message body were silently dropped (this was a regeression introduced by some of the recent optimizations)

| * | | bugfix: potential segfault in output file writer (omfile)Rainer Gerhards2009-08-182-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In async write mode, we use modular arithmetic to index the output buffer array. However, the counter variables accidently were signed, thus resulting in negative indizes after integer overflow. That in turn could lead to segfaults, but was depending on the memory layout of the instance in question (which in turn depended on a number of variables, like compile settings but also configuration). The counters are now unsigned (as they always should have been) and so the dangling mis-indexing does no longer happen. This bug potentially affected all installations, even if only some may actually have seen a segfault.

| * | | | bugfix? (unconfirmed, testing): segfault when writing asynchronouslyRainer Gerhards2009-08-181-2/+8
| |/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have undone a very small optimization with using pre-malloced memory, which seems to have some issues. Now I am doing mallocs and at least in test environment this seems to solve the issue. The code now needs more review. If it runs flawlessly for some time, I may try to re-enable to pre-malloc, but not necessarily: its performance benefit is very mild (aka: I don't think it justifies introducing bigger complexities).

* | | | internal: added ability to terminate input modules not via pthread_cancel...Rainer Gerhards2009-07-205-5/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ... but an alternate approach via pthread_kill. This is somewhat safer as we do not need to think about the cancel-safeness of all libraries we use. However, not all inputs can easily supported, so this now is a feature that can be requested by the input module (the most important ones request it).
* | | | cleanup & better debug message handlingRainer Gerhards2009-07-201-66/+65
| | | | | | | | | | | | | | | | | | | | | | | | the new handling will hopefully spare a few cycles, as function calls (and most importantly parameter generation!) or now only done when debug messages are actually active.

* | | | solved potential race condition and some cleanupRainer Gerhards2009-07-202-6/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | code review brought up some few places where we may have run into a race. They have most probably been introduced during the recent set of changes. But I do not look at older versions because of the changed architecture, one can not simply backport this patch.
* | | | bugfix: minor static memory leak while reading configurationRainer Gerhards2009-07-204-19/+15
| | | | | | | | | | | | | | | | | | | | This did NOT leak based on message volume. Also, did some cleanup during the commit.
* | | | enhanced worker thread pool by atomic opsRainer Gerhards2009-07-203-32/+23

* | | | architecture change: queue now always has at least one worker threadRainer Gerhards2009-07-204-19/+20
| | | | | | | | | | | | | | | | | | | | | | | | ...if not running in direct mode. Previous versions could run without any active workers. This simplifies the code at a very small expense. See v5 compatibility note document for more in-depth discussion.

* | | | further code simplificationRainer Gerhards2009-07-176-176/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ... could even remove one mutex by using a better algorithm. I think I also spotted some situation in which a hang could have happened. As I can't fix it in v4 and less without moving to the new engine, I make no effort in testing this out. Hangs occur during shutdown, only (if at all). The code changes should also result in some mild performance improvement. Some bug potential, but overall the bug potential should have been greatly reduced.
