... however, I did not not a test run due to the lack of
existing test drivers and the very low (aka "non-existing" interest
from the userbase in the feature).

Previous versions inserted garbage (the pointer was interpreted as the
string itself). It seems inserting arrays of strings is not that easy
with OCI.
This approach consumes 2KB per entry in the batch, so if you have
batches of size 1000 you'll be using 2MB for the batch. This size
doesn't change, anyways and the risk of leaking memory is gone. OCI
doesn't deal well with batches of strings. :(

Literal strings passed in the statement may contain ':', let's not
count them.

We'll receive a single statement to be prepared and a batch
size. Then, doAction will execute the statement only once per batch
hit, making the process much more efficient.
This will reduce network and DB server overhead. The downside is that
this version cannot be used with rsyslog v3 anymore. If anyone is
interested on backporting the module, they should choose all patches
up to this one.
Better documentation may follow.

When rsyslog shuts down, we must send and commit any pending messages
or information will be lost. It will make rsyslog's shut down slower,
but also more reliable.

Currently, all statements to be executed are stored on the same
structure. When the batch size is reached, all statements are executed
in a single transaction, and then committed.
There are many corner cases in which an error may happen and the batch
may be left in an inconsistent state, perhaps leaking memory or
crashing. They will be fixed.

Instead of using the old-style configuration parameters, use
$... directives, which lead to simpler code, and also should make
user's configurations simpler. Needs some testing.
Currently, the supported directives are $OmoracleDB, $OmoracleDBUser
and $OmoracleDBPassword. $OmoracleDBStatement and $OmoracleDBBatchSize
may follow.

Emacs doesn't allow for proper indentation with rsyslog's macros (no
curly brackets, so it doesn't know where functions start), so I had to
manually add such indentation.
Add support for retrying actions, namely, disconnect from the DB,
re-connecting and re-executing the last prepared statement. Needs to
be tested.

It now runs SQL statements given as templates. In this case, the
template is given on the configuration file and the core passes the
SQL statement correctly formatted to doAction. I still need to decide
how to structure this for having prepared statements (prepare them at
parseSelector time) and then make doAction to only bind arguments and
execute. It commits after each statement, which is awfully slow but
good enough for the moment.
Next step after that is have a buffer of arguments, and make doAction
store new data as it arrives, then run the statement only when the
buffer is almost full. Or something like that.

It will read and parse the config line (this code is not yet
rock-solid) and connect to the database at initialization time. I also
cleaned some debug messages that are not needed anymore.

The testbench has now a generic driver that can run a whole class
of test suites just by providing a config file and test cases. This
does not cover all testing needs, but a lot.
We have now added one test for the new array-passing output plugin
interface.

| | | | | | |
| | | | | | |

This is more efficient for some outputs. They new can receive fields not only
as a single string but rather in an array where each string is seperated.

to make sure only the minimum number of file handles is left open
during a exec call. This is not a 100% solution, as there are also
some fopen() calls and, more importantly, file descriptors opened
by libraries. But it is better than nothing (and it was quick, at
least until we run into platform hell, what we will for sure ;)).

worked on ways to provide a better test suite:
- added -T rsyslogd command line option, enables to specify a directory
where to chroot() into on startup. This is NOT a security feature but
introduced to support testing. Thus, -T does not make sure chroot()
is used in a secure way. (may be removed later)
- added omstdout module for testing purposes. Spits out all messages to
stdout - no config option, no other features
- modified $ModLoad statement so that for modules whom's name starts with
a dot, no path is prepended (this enables relative-pathes and should
not break any valid current config)

so far, this is mostly some documentation, but I hope that during
the process of creating output modules out of it we will get good
questions and thus can extend the template. In any case, it should
be better than what we had so far...

Remove AC_CHECK_HEADERS([mysql/mysql.h],...) as this was causing pain
for users where the mysql headers are not installed in the system include
directory. It was superfluous anyways, as we check for mysql_config and
set the include path to the correct directory.
Update ommysql.c to use #include <mysql.h>, as mysql_config will set the
include path to /path/to/include/mysql/ so <mysql/mysql.h> would not
work.
Remove errmsg.h include as it is not used.

pkg-config uses uppercase for its _CFLAGS and _LIBS variable names.
So we follow suit and convert all _cflags and _libs variables to
uppercase for more consistency.

- added $InputTCPServerAddtlFrameDelimiter config directive, which
enabeles to specify an additional, non-standard message delimiter
for processing plain tcp syslog. This is primarily a fix for the invalid
framing used in Juniper's NetScreen products. Credit to forum user
Arv for suggesting this solution.
- added $InputTCPServerInputName property, which enables a name to be
specified that will be available during message processing in the
inputname property. This is considered useful for logic that treats
messages differently depending on which input received them.
