Base version string on 'git describe --long', and provide cpp
macros in jemalloc.h.
Add the version mallctl.

Remove all functionality related to tracing. This functionality was
useful for understanding memory fragmentation during early algorithmic
design of jemalloc, but it had little utility for non-trivial
applications, due to the sheer volume of data written to disk.

Add mallctl interfaces for profiling parameters.
Fix a file descriptor leak in heap profile dumping.
|
| |
|
|
|
| |
If JEMALLOC_PROF_PREFIX is set in the environment, use it as the
filename prefix when dumping heap profiles, rather than "jeprof".

Add the --enable-prof and --enable-prof-libunwind configure options.
Add the B/b, F/f, I/i, L/l, and U/u JEMALLOC_OPTIONS.
Interval-based profile dump triggering is not yet implemented.
Add supporting generic code:
* Add memory barriers.
* Add prn (LCG PRNG).
* Add hash (Murmur hash function).
* Add ckh (cuckoo hash tables).

This feature caused significant performance degradation, and the
fragmentation reduction benefits were difficult to quantify.

Fix a type mismatch for "arenas.nlruns" mallctl access. This bug caused
a crash during statistics printing on 64-bit systems.
Fix the "stats.active" mallctl to include active memory in huge objects.
Report active bytes for the whole application, as well as per arena.
Remove several unused variables.

Replace chunk stats code that was missing locking; this fixes a race
condition that could corrupt chunk statistics.
Converting malloc_stats_print() to use mallctl*().
Add a missing semicolon in th DSS code.
Convert malloc_tcache_flush() to a mallctl.
Convert malloc_swap_enable() to a set of mallctl's.
|
| |
|
|
|
|
|
|

Add malloc_swap_enable().
Add the O/o JEMALLOC_OPTIONS flags, which control memory overcommit.
Fix mapped memory stats reporting for arenas.
|
| |
|
|
|
| |
Add the w4opaque argument malloc_message() and malloc_stats_print(), and
propagate the change through all the internal APIs as necessary.
|
| |
|
|
| |
Add the "m" and "a" opts flags for malloc_stats_print().
|
| |
|
|
| |
Add malloc_cprintf() and malloc_vcprintf().
|
| |
|
|
| |
Fix some bugs in the Makefile's install target.

rather than just enabling/disabling the tcache.
Fix an off-by-one bug in large object stats recording.
|
| |
|
|
| |
just enabling/disabling GC.
|
| |
|
|
|

Incrementally merge tcache stats, so that malloc_stats_print() always reports
at least most events that have occurred thus far.
|

Add dirty page tracking for pages within active small/medium object runs.
Reduce chunks_dirty red-black tree operations via lazy updating.
|
| |
|
|
|
|
|
|
| |
Add the 'G'/'g' and 'H'/'h' MALLOC_OPTIONS flags.
Add the malloc_tcache_flush() function.
Disable thread-specific caching until the application goes multi-threaded.
|
| |
|
|
|
|
|
|
|
|
|

Add the 'M' and 'm' MALLOC_OPTIONS flags, which control the maximum medium size
class.
Relax the cap on small/medium run size to arena_maxclass.
Reduce arena_run_reg_dalloc() integer division code complexity.
Increase the default chunk size from 1MiB to 4MiB.

and heap allocation are always enabled.

Rename jemalloc_options-->malloc_options and jemalloc_message-->malloc_message.

jemalloc is configured.
Modify arena_malloc() API to avoid unnecessary choose_arena() calls. Remove
unnecessary code from choose_arena().
Enable lazy-lock by default, now that choose_arena() is both faster and out of
the critical path.
Implement objdir support in the build system.
