ctime: Fix updating ctime in rename and unlink

2018-05-24T07:42:39+00:00

1. Successful rename was not updating ctime.
   Fixed the same.
2. Successful unlink when link count is more than 1
   was not updating ctime. Fixed the same.
3. Copy ctime and flags during frame copy.

posix/ctime: posix hook to set ctime xattr in relevant fops

2018-05-06T01:39:08+00:00

This patch uses the ctime posix APIs to set consistent
time across replica on disk. It also stores the time
attributes in the inode context.

rpc/*: auth-header changes

2018-01-17T06:00:39+00:00

Introduce another authentication header which can now send more data.
This is useful because this data can be common for all the fops, and
we don't need to change all the signatures.

As part of this, made rpc-clnt.c little more modular to support multiple
authentication structures.

stack.h changes are placeholder for the ctime etc, can be moved later
based on need.

updates #384

libglusterfs: fix the call_stack_set_group() function

2017-11-24T16:54:44+00:00

- call_stack_set_group() will take the ownership of passed
  buffer from caller;
- to indicate the change, its signature is changed from
  including the buffer directly to take a pointer to it;
- either the content of the buffer is copied to the
  groups_small embedded buffer of the call stack, or
  the buffer is set as groups_large member of the call
  stack;
- the groups member of the call stack is set to,
  respectively, groups_small or groups_large, according
  to the memory management conventions of the call stack;
- the buffer address is overwritten with junk to effectively
  prevent the caller from using it further on.

Also move call_stack_set_group to stack.c from stack.h
to prevent "defined but not used [-Wunused-function]"
warnings (not using it anymore in call_stack_alloc_group()
implementation, which saved us from this so far).

protocol/server: refactor gid_resolve()

In gid_resolve there are two cases:
either the gid_cache_lookup() call returns
a value or not. The result is caputured in
the agl variable, and throughout the function,
each particular stage of the implementation
comes with an agl and a no-agl variant.

In most cases this is explicitly indicated
via an

   if (agl) {
      ...
   } else {
      ...
   }

but some of this branching are expressed via
goto constructs (obfuscating the fact we stated
above, that is, each particular stage having
an agl/no-agl variant).

In the current refactor, we bring the agl
conditional to the top, and present the
agl/non-agl implementations sequentially.

Also we take the opportunity to clean up and
fix the agl case:
- remove the spurious
    gl.gl_list = agl->gl_list;
  setting, as gl is not used in the agl caae
- populate the group list of call stack from
  agl, fixing thus referred BUG.

Also fixes BUG: 1513920

xlator: add more metrics per fops

2017-11-08T08:33:22+00:00

Make sure to handle these counters in STACK_WIND/UNWIND macro, and
keep the counters as part of xlator_t structure itself, to provide
infra to monitoring.

stack: change gettimeofday() to clock_gettime()

2017-11-06T14:23:49+00:00

For achieving the above, needed below changes too.

* more sanity into how 'frame->op' is assigned.
* infra to have 'stats' as separate section in 'xlator_t' structure

stack.h:PW.INCLUDE_RECURSION

2017-09-29T07:46:53+00:00

The headerfile globals.h is recursively adding itself.
( globals.h -> xlator.h -> stack.h -> globals.h).
We are finding the source files which are including the header
file globals.h and removing the inclusion line.

I used git grep -l stack.h | xargs git grep globals.h --
to find out the files and removed the header file from all files
except libglusterfs/src/xlator.h and libglusterfs/src/Makefile.am

When I try to remove header file from libglusterfs/src/xlator.h
I'm getting some errors. In libglusterfs/src/Makefile.am it is
required for building RPMs.
