logging: remove unused message-id scripts

2014-05-24T15:26:08+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.

libglusterfs: Add monotonic clocking counter for timer thread

2013-10-15T07:14:57+00:00

gettimeofday() returns the current wall clock time and timezone.
Using these functions in order to measure the passage of time
(how long an operation took) therefore seems like a no-brainer.

This time suffer's from some limitations:

a. They have a low resolution: “High-performance” timing by
definition, requires clock resolutions into the microseconds
or better.

b. They can jump forwards and backwards in time: Computer
clocks all tick at slightly different rates, which causes
the time to drift. Most systems have NTP enabled which
periodically adjusts the system clock to keep them in sync
with “actual” time. The adjustment can cause the clock to
suddenly jump forward (artificially inflating your timing
numbers) or jump backwards (causing your timing calculations
to go negative or hugely positive). In such cases timer
thread could go into an infinite loop.

From 'man gettimeofday':
----------
..
..
The time returned by gettimeofday() is affected by discontinuous
jumps in the system time (e.g., if the system administrator manually
changes the system time).  If you need a monotonically increasing
clock, see clock_gettime(2).
..
..
----------

Rationale:

For calculating interval timing for Timer thread, all that’s
needed should be clock as a simple counter that increments
at a stable rate.

This is necessary to avoid the jumps which are caused by using
"wall time", this counter must be monotonic that can never
“tick” backwards, ever.

libglusterfs: add glusterfs-acl.h to Makefile.am

Without this, glusterfs-acl.h is left out of 'make dist'
and building RPM fails.

parser: use private namespace 'graphyy' instead of 'yy'

This can cause linker errors when accessing glusterfs through
libgfapi if the caller also uses a parser with 'yy' prefix.

libglusterfs/client_t client_t implementation, phase 1

2013-07-30T05:22:21+00:00

Implementation of client_t

The feature page for client_t is at
http://www.gluster.org/community/documentation/index.php/Planning34/client_t

In addition to adding libglusterfs/client_t.[ch] it also extracts/moves
the locktable functionality from xlators/protocol/server to libglusterfs,
where it is used; thus it may now be shared by other xlators too.

This patch is large as it is. Hooking up the state dump is left to do
in phase 2 of this patch set.

(N.B. this change/patch-set supercedes previous change 3689, which was
corrupted during a rebase. That change will be abandoned.)

log: error code generation support

2013-07-19T10:55:15+00:00

error code and message are generated at compile time by reading a json
file which contains information of elements for each error code.  This
framework provides error handling and ability to do more cleaner log
messages to users.

error-codes.json file contains error description is below format

{
    "ERR_NAME": {"code": ERR_NUM,
                 "message": {"LOCALE": "ERR_MESSAGE"}}
}

At compile time autogen.sh calls gen-headers.py which produces C
header file libglusterfs/src/gf-error-codes.h.  This header has a
function

const char *_gf_get_message (int code);

which returns respective ERR_MESSAGE for given ERR_NUM.
