Do not hardcode umount(8) path, emulate lazy umount

2014-10-03T15:01:29+00:00

1) Use a system-dependent macro for umount(8) location instead of
relying on $PATH  to find it, for security and portability sake.

2) Introduce gf_umount_lazy() to replace umount -l (-l for lazy) invocations,
which is only supported on Linux; On Linux behavior in unchanged. On other
systems, we fork an external process (umountd) that will take care of
periodically attempt to unmount, and optionally rmdir.

logging: remove unused message-id scripts

2014-05-22T09:48:58+00:00

The current unused implementation for message-ids in the logs depends on
automatically generated files. The generated files are not included in
the distributed tarball. This causes issues when distributions build
packages, they need to re-run ./autogen.sh to create the needed files.

I thought of including the generated files in the distribution tarball.
However, the contents of these files are not actively used, so it seems
to make more sense to drop it all together. These functions were the
only users of libintl and gettext too, so dropped the requirement
checking from configure.ac.

A replacement for the message-id logging framework is in progress. Any
changes that this patch makes, can be reverted in the submission of
patches for the new framework.

log: enhance gluster log format with message ID and standardize errno reporting

2014-03-28T11:53:37+00:00

	Currently there are quite a slew of logs in Gluster that do not
	lend themselves to trivial analysis by various tools that help
	collect	and monitor logs, due to the textual nature of the logs.

	This FEAT is to make this better by giving logs message IDs so
	that the tools do not have to do complex log parsing to break
	it down to problem areas and suggest troubleshooting options.

	With this patch, a new set of logging APIs are introduced that
	take additionally a message ID and an error number, so as to
	print the message ID and the descriptive string for the error.

	New APIs:
		- gf_msg, gf_msg_debug/trace, gf_msg_nomem, gf_msg_callingfn

	These APIs follow the functionality of the previous gf_log*
	counterparts, and hence are 1:1 replacements, with the delta
	that, gf_msg, gf_msg_callingfn take additional parameters as
	specified above.

	Defining the log messages:
	Each invocation of gf_msg/gf_msg_callingfn, should provide an ID
	and an errnum (if available). Towards this, a common message id
	file is provided, which contains defines to various messages and
	their respective strings. As other messages are changed to the
	new infrastructure APIs, it is intended that this file is edited
	to add these messages as well.

	Framework enhanced:
	The logging framework is also enhanced to be able to support
	different logging backends in the future. Hence new configuration
	options for logging framework and logging formats are introduced.

	Backward compatibility:
	Currently the framework supports logging in the traditional
	format, with the inclusion of an error string based on the errnum
	passed in. Hence the shift to these new APIs would retain the log
	file names, locations, and format with the exception of an
	additional error string where applicable.

	Testing done:
	Tested the new APIs with different messages in normal code paths
	Tested with configurations set to gluster logs (syslog pending)
	Tested nomem variants, inducing the message in normal code paths
	Tested ident generation for normal code paths (other paths
		pending)
	Tested with sample gfapi program for gfapi messages
	Test code is stripped from the commit

	Pending work (not to be addressed in this patch (future)):
	- Logging framework should be configurable
	- Logging format should be configurable
	- Once all messages move to the new APIs deprecate/delete older
	  APIs to prevent misuse/abuse using the same
	- Repeated log messages should be suppressed (as a configurable
	  option)
	- Logging framework assumes that only one init is possible, but
	  there is no protection around the same (in existing code)
	- gf_log_fini is not invoked anywhere and does very little
	  cleanup (in existing code)
	- DOxygen comments to message id headers for each message

build: Start using library versioning for various libraries

2014-01-18T16:51:14+00:00

According to libtool three individual numbers stand for
CURRENT:REVISION:AGE, or C:R:A for short. The libtool
script typically tacks these three numbers onto the end
of the name of the .so file it creates. The formula for
calculating the file numbers on Linux and Solaris is

   /path/to/library/.(C - A).(A).(R)

As you release new versions of your library, you will
update the library's C:R:A. Although the rules for changing
these version numbers can quickly become confusing, a few
simple tips should help keep you on track. The libtool
documentation goes into greater depth.

In essence, every time you make a change to the library and
release it, the C:R:A should change. A new library should start
with 0:0:0. Each time you change the public interface
(i.e., your installed header files), you should increment the
CURRENT number. This is called your interface number. The main
use of this interface number is to tag successive revisions
of your API.

The AGE number is how many consecutive versions of the API the
current implementation supports. Thus if the CURRENT library
API is the sixth published version of the interface and it is
also binary compatible with the fourth and fifth versions
(i.e., the last two), the C:R:A might be 6:0:2. When you break
binary compatibility, you need to set AGE to 0 and of course
increment CURRENT.

The REVISION marks a change in the source code of the library
that doesn't affect the interface-for example, a minor bug fix.
Anytime you increment CURRENT, you should set REVISION back to 0.
