472c0d7877 Add Valgrind mempool support. 
Compile with -DUSE_VALGRIND. It will attempt to keep Valgrind
informed of our memory allocations. Frees are trickier since they
may be deferred indefinitely.

644506db6b ITS#6437: Fix pool version misalignment: It aligned heads, not returned blocks 2010-01-05 23:31:14 +00:00

705bd5bf40 ITS#6437, move structs slab_object and slab_heap from slap.h to sl_malloc.c 2010-01-05 23:14:14 +00:00
Hallvard Furuseth
1af33a46c9 ITS#6437, save space: Do not allocate the tail, except if size==0. 
Store a tail only in freed blocks.  (Alignment ensures there will
be room.)  Put the freed mark in next block's head.

d515f24255 ITS#6437 cleanup (noop patch): Join SLAP_NO_SL_MALLOC code with identical 
ctx==NULL code.  Add enum No_sl_malloc to avoid #ifdef SLAP_NO_SL_MALLOC.

5d883c044a ITS#6437, follow up previous fixes: 
Ensure Align >= sizeof(ber_len_t), to clarify the code's requirements.
Rearrange a slap_sl_malloc() branch to factor out ch_malloc fallbacks.
Fix range check (ptr+size >= endptr) -> (size >= endptr-ptr).  Fix debug msg.

4e66da4ec1 ITS#6437, slap_sl_calloc(): 
Check count*size overflow. Omit slap_sl_malloc failure check, it cannot fail.
 2010-01-02 22:53:22 +00:00
Hallvard Furuseth
423c13a6d6 ITS#6437, failure/fallback/debug handling: 
slap_sl_malloc could return failure. Exit instead, like the rest of sl_malloc.
Since we increase size, reduce it before Debug() and/or fallback to ch_malloc.
Debug() before exit() on failure.  Tweak debug formats and a comment.

46b99131cb ITS#6437 cleanup (noop change): 
Move thread/nothread code to macros SET_MEMCTX()/GET_MEMCTX().
Rename some thread/memory contexts 'ctx' to thrctx/memctx to avoid confusion.

cc58227437 ITS#6437, fixes for stack implementation of slap_sl_realloc(): 
Preserve 2*int alignment on hosts where sizeof(int) == sizeof(ber_len_t).
If realloc of last block falls back to ch_malloc, free last block properly.
Fix range check (ptr + size < endptr) --> (size < endptr - ptr).

062021e731 ITS#6437, slap_sl_mem_create(): 
Bugfix: Switching implementation stack<->pool on an old context could
        crash or leak, it ran the wrong implementation's cleanup code.
Cleanup:  Factor out identical stack/pool code.  Call
          slap_sl_mem_destroy(NULL,) instead of copying its pool code.
API change: slap_sl_mem_destroy(key=NULL,) gets a new meaning.  Does
            not affect current OpenLDAP code, it never passed NULL.
