core: reduce the usage of global variables

2012-08-03T09:01:52+00:00

* move all the 'logging' related global variables into ctx
* make gf_fop_list a 'const' global array, hence no init(),
  no edits.
* make sure ctx is allocated without any dependancy on
  memory-accounting infrastructure, so it can be the first
  one to get allocated
* globals_init() should happen with ctx as argument

not yet fixed below in this patchset:
* anything with 'THIS' related globals
* anything related to compat_errno related globals as its
  one time init'd and not changed later on.
* statedump related globals

mempool: add more counters to understand the usage scenarios properly

2012-02-27T10:18:35+00:00

current design of mempool is to fallback to standard calloc/free if
all the buffers in pool are exhausted. Understanding more about those
numbers will help us to tune mempool parameters properly over time.

libglusterfs: fix GF_FREE

2012-02-27T10:15:51+00:00

Argument-taking macros should be possible to use with
same syntax that of C functions. In particular (assuming
FOO is a single-argument macro),

  FOO(bar)

should break and

  if (cond)
    FOO(bar);
  else
    baz();

should compile.

statedump: add more memory accounting related stats

2011-09-22T11:33:40+00:00

* iobuf: add variable to keep count of total number of allocations
* iobuf: include 'purged' and 'filled' arenas also in dump
* mempool: more details added (with a name to tell why mem-pool
  is created)
* memory-accounting: print number of allocs in each type

this would give us much better understanding of the memory
allocation pattern

mem-pool: Make mem-pool ptr avialable in ptr

2011-08-25T19:01:08+00:00

The header of the ptr returned from mem-pool will now store the
mem-pool ptr it belongs to. mem_put will now take only the pointer
to be freed.

Also, changing MALLOC call to GF_CALLOC in mem_get when we run out
of entries in mem-pool. This also will have the header information
saved.
