geo-rep / gsyncd: Separate log file directory for Mountbroker sessions

2013-02-05T01:34:56+00:00

... so that a mountbroker session which is initiated b/w master
and slave does not use the same log file if it's started after
a normal geo-rep session b/w master and slave. This results in
EPERM as the log file is owned by root and the geo-rep slave
process (now running as a non privileged user) does not have
access to it.

Also, having separate log file directory for mountbroker sessions
looks clean.

NOTE: geo-rep's client mount log file location remains unchanged.

geo-rep: do not access BaseException.message in syncdutils

2012-12-18T22:17:35+00:00

http://www.python.org/dev/peps/pep-0352/ explains that the .message
property of BaseException is being removed. Most of the other exception
handlers access .args[] which should be suitable for this
case too.

geo-rep / gsyncd: play nicely with peer multiplexing when setting a checkpoint

2012-12-04T20:13:02+00:00

The gsyncd invocation that instruments the "geo-rep config" command is
multiplexed over peers to ensure the uniformity of configuration.
In general, that works well, but checkpoint setting is a special case,
because (unlike other instances of config-set) it is logged (as recording
of checkpoint events is part of the feature).

Problem is that the path components leading to the log file are
created only on the original node, where gsyncd was started.
Therefore the logging attempt will fail on the other nodes.

Fix: ignore if opening the logfile on behalf of checkpoint setting
fails with ENOENT.

geo-replication: catch select.error on select()

2012-11-29T00:23:49+00:00

tailer() in resource.py does not correctly catch exceptions from
select(). select() can raise an instance of the select.error class and
the current expression only catches ValueError (and the instance will
have reference called selecterror).

The geo-rep log contains a call trace like this:
> E [syncdutils:190:log_raise_exception] : FAIL:
> Traceback (most recent call last):
> File "/usr/libexec/glusterfs/python/syncdaemon/syncdutils.py", line 216, in twrap

build: split CPPFLAGS from CFLAGS

2012-10-03T19:26:45+00:00

Automake provides a separate variable for preprocessor flags
(*_CPPFLAGS). They are already uses in a few places, so make it
consistent and use it everywhere. Note that cflags obtained from
pkg-config often are cppflags, which is why LIBXML2_CFLAGS moves with
into AM_CPPFLAGS, for example.

build: remove useless explicit -fPIC -shared from

2012-10-03T19:24:59+00:00

 CFLAGS

libtool will automatically add "-fPIC" to the compiler command line as
needed, so there is no need to specify it separately.

"-shared" is normally a linker flag and has an odd effect when used with
libtool --mode=compile, namely that it inhibits production of static
objects. For that however, using AC_DISABLE_STATIC is a lot simpler.

This adds -D${GF_HOST_OS} to some compiler command lines,

GF_CFLAGS seems missing in two spots.

In one of those, adding it to libgfapi_la_CFLAGS would make it equal
to AM_CFLAGS, so remove libgfapi_la_CFLAGS there.
