This is an initial take at renaming the project to Monitoring Plugins.
It's not expected to be fully complete, and it is expected to break
things (The perl module for instance). More testing will be required
before this goes mainline.

In utils.sh, $ECHO was set to printf(1) or echo(1), depending on whether
printf(1) is available in /usr/bin. This resulted in various bugs, as
printf(1) cannot be used in the same way as echo(1).
Thanks to Trevor Hemsley for reporting one of those bugs: If $ECHO was
set to printf(1), check_log stumbled when reporting a log line with a
"%" character.

AM_CONFIG_HEADER is deprecated.

also grandparents make this test fail but is not a problem in real live.
NPTest->testCmd uses "sh -c" already, so there is no need to do that twice.

Closes #1205.

This fixes an issue that appears when running check_procs over NRPE,
where the default shell is configured to (for example) dash, as is the
case on Debian.
dash (and tcsh, and mksh, and probably others), when invoked with -c forks an additional process
to execute the argument string. Contrast this with bash, which does not
do this, provided that the argument string simply can be exec()'d as-is.
To demonstrate:
$ bash -c pstree
init─┬ ..
...
├─sshd─-─sshd───pstree
versus
$ dash -c pstree
init─┬ ..
...
├─sshd─-─sshd───dash───pstree
The consequence of this fork is that the following invocation:
/opt/plugins/check_procs -a init
will result in this output:
PROCS OK: 2 processes with args 'init' | processes=2;;;0;
because the check_procs, in addition to finding the actual init process,
finds its parent shell as well.
This example is a bit contrived, but I think it illustrates the
point.
This wouldn't really be a problem, and normally isn't, if it weren't
for the fact that NRPE uses a call to popen() which does exactly the
above (executes '/bin/sh -c ...'), causing inconsistent behaviour
between distributions and much confusion for end users.
The argument may be made that the dash process spawned by NRPE is just a
process like any other, and should therefore be included in the process
count just like any other. However, this is not very intuitive, because
of the previously mentioned inconsistencies.
The argument might also well be made that we're _never_ interested in the
immediate ancestor of the plugin, and while it is unknown how many
installations have already made the necessary modifications to their
setups to make up for the fact that the plugin behaves the way it does,
it is not deemed worthwhile to entertain such workarounds.
Thus, this patch ignores the parent process.

We don't run a Tinderbox instance anymore. (Noted by "zathras" on IRC.)

Add a note regarding the removal of the "contrib" directory to the NEWS
file. This note is missing from the NEWS file shipped with the 1.5
release, though.

Testing "nagiosplugins.org" will currently not work.

Add the tools/generate-change-log script for auto-generating the
ChangeLog file from the Git history when running "make dist".
|
|
We moved our web site away from Drupal and the snapshots/guidelines away
from SourceForge. The new infrastructure scripts will be maintained in
a separate repository together with the Markdown source of the new web
site.

We no longer mirror out Git repositories into Subversion.

Fixes issue where if an SSL initialization error occurs on a redirect
using -f follow the plugin still returns an OK state.
Closes #1159.

- Write "plugin" instead of "plug-in".
- Write "development guidelines" instead of "developer guidelines"
- Capitalize "Nagios Plugin Development Guidelines".

Add a symlink so that GitHub renders the README file as Markdown.

The BUGS file wasn't maintained properly anymore. And doing so makes no
sense. That's what the bug tracker is for.
|
|
Use the Markdown format for the README file and apply various minor
cosmetic changes.

Since commit 912df3ef9b188c82893dace1e9b56c42a558fdba, check_pgsql
exited UNKNOWN instead of OK if the new --query option was *not*
specified. This bug is fixed now.

Tests sometimes fila when running multiple parallel tests using the
same cache file because it is written everytime a test parameter
is read. Since there is no locking, this might fail from time to time.

newer (or x86) solaris implementations have interface names like e1000g0
which includes numbers. So we reverse the interface number detection to
get the last number, instead of the first number.

the reason why it still worked sometimes was fsu_blocks beeing uninitialized
which resulted in a true test sometimes.

at least on freebsd, there are a processes with state 'S', they always
use two character status.
