From 9ac54f0d7d70b8a9879889b4522a1d552fca1100 Mon Sep 17 00:00:00 2001
From: Noriko Hosoi <nhosoi@momo7.localdomain>
Date: Thu, 12 Jul 2018 11:52:04 -0700
Subject: [PATCH] Introducing an option preservecase to imudp and imtcp module
for managing the case of FROMHOST value.
Usage:
module(load="imudp" [preservecase="on"|"off"])
module(load="imtdp" [preservecase="on"|"off"])
If preservecase="on", FROMHOST value is handled in the case sensitive manner.
If preservecase="off", FROMHOST value is handled in the case insensitive manner.
To maintain the current behaviour, the default value of preservecase is
"on" for imtcp and "off" for imudp.
Incremented tcpsrvCURR_IF_VERSION by 1.

From 3987cd929d859f900318b393133c3bdde8dfffd5 Mon Sep 17 00:00:00 2001

Subject: [PATCH] mmkubertnetes: action fails preparation cycle if kubernetes
API destroys resource during bootup sequence
The plugin was not handling 404 Not Found correctly when looking
up pods and namespaces. In this case, we assume the pod/namespace
was deleted, annotate the record with whatever metadata we have,
and cache the fact that the pod/namespace is missing so we don't
attempt to look it up again.
In addition, the plugin was not handling error 429 Busy correctly.
In this case, it should also annotate the record with whatever
metadata it has, and _not_ cache anything. By default the plugin
will retry every 5 seconds to connect to Kubernetes. This
behavior is controlled by the new config param `busyretryinterval`.
This commit also adds impstats counters so that admins can
view the state of the plugin to see if the lookups are working
or are returning errors. The stats are reported per-instance
or per-action to facilitate using multiple different actions
for different Kubernetes servers.
This commit also adds support for client cert auth to
Kubernetes via the two new config params `tls.mycert` and
`tls.myprivkey`.

From e8d64cbd15fa84907dc23f8b52d6f2f847b46fec Mon Sep 17 00:00:00 2001
From: Rich Megginson <rmeggins@redhat.com>
Date: Mon, 10 Sep 2018 17:25:38 -0600
Subject: [PATCH] imfile: support for endmsg.regex
This adds support for endmsg.regex. It is similar to
startmsg.regex except that it matches the line that denotes
the end of the message, rather than the start of the next message.
This is primarily for container log file use cases such as this:
date stdout P start of message
date stdout P middle of message
date stdout F end of message
The `F` means this is the line which contains the final part of
the message. The fully assembled message should be
`start of message middle of message end of message`.
`startmsg.regex="^[^ ]+ stdout F "` will match.
(cherry picked from commit c902a0938fe163b5351829d2b72001d024895c16)
(cherry picked from commit dd4a72c4d52d8da98ed6b86114868e1a450ccb41)

From f85ef7aabcec84497a5eaf9670616b3402c79d9c Mon Sep 17 00:00:00 2001

Subject: File rotation with imfile broken
Previously, truncation was only detected at end of file. Especially with
busy files that could cause loss of data and possibly also stall imfile
reading. The new code now also checks during each read. Obviously, there
is some additional overhead associated with that, but this is unavoidable.
It still is highly recommended NOT to turn on "reopenOnTruncate" in imfile.
Note that there are also inherant reliability issues. There is no way to
"fix" these, as they are caused by races between the process(es) who truncate
and rsyslog reading the file. But with the new code, the "problem window"
should be much smaller and, more importantly, imfile should not stall.
A change in the inode was not detected under all circumstances,
most importantly not in some logrotate cases.
Includes new tests made by Andre Lorbach. They now use the
logrotate tool natively to reproduce the issue.
