Add mallctl*() unit tests.
2013-12-19 15:21:42 +08:00
#include "test/jemalloc_test.h"
Add partial name-to-mib functionality
2020-08-14 02:28:22 +08:00
#include "jemalloc/internal/ctl.h"
Hooks: Add a hook exhaustion test. When we run out of space in which to store hooks, we should return EAGAIN from the mallctl, but not otherwise misbehave.
2018-05-01 07:24:36 +08:00
#include "jemalloc/internal/hook.h"
Header refactoring: move util.h out of the catchall
2017-04-12 04:31:16 +08:00
#include "jemalloc/internal/util.h"
Update brace style. Add braces around single-line blocks, and remove line breaks before function-opening braces. This resolves #537.

Implement per-CPU arena. The new feature, opt.percpu_arena, determines thread-arena association dynamically based CPU id. Three modes are supported: "percpu", "phycpu" and disabled. "percpu" uses the current core id (with help from sched_getcpu()) directly as the arena index, while "phycpu" will assign threads on the same physical CPU to the same arena. In other words, "percpu" means # of arenas == # of CPUs, while "phycpu" has # of arenas == 1/2 * (# of CPUs). Note that no runtime check on whether hyper threading is enabled is added yet. When enabled, threads will be migrated between arenas when a CPU change is detected. In the current design, to reduce overhead from reading CPU id, each arena tracks the thread accessed most recently. When a new thread comes in, we will read CPU id and update arena if necessary.

TEST_MALLCTL_OPT(bool, background_thread, always);
Refactor *decay_time into *decay_ms. Support millisecond resolution for decay times. Among other use cases this makes it possible to specify a short initial dirty-->muzzy decay phase, followed by a longer muzzy-->clean decay phase. This resolves #812.

TEST_MALLCTL_OPT(bool, stats_print, always);
Implement opt.stats_interval and the _opts options. Add options stats_interval and stats_interval_opts to allow interval based stats printing. This provides an easy way to collect stats without code changes, because opt.stats_print may not work (some binaries never exit).

Introduce two new modes of junk filling: "alloc" and "free". In addition to true/false, opt.junk can now be either "alloc" or "free", giving applications the possibility of junking memory only on allocation or deallocation. This resolves #172.

Remove --disable-tcache. Simplify configuration by removing the --disable-tcache option, but replace the testing for that configuration with --with-malloc-conf=tcache:false. Fix the thread.arena and thread.tcache.flush mallctls to work correctly if tcache is disabled. This partially resolves #580.

TEST_MALLCTL_OPT(bool, tcache, always);
Add opt.lg_extent_max_active_fit When allocating from dirty extents (which we always prefer if available), large active extents can get split even if the new allocation is much smaller, in which case the introduced fragmentation causes high long term damage. This new option controls the threshold to reuse and split an existing active extent. We avoid using a large extent for much smaller sizes, in order to reduce fragmentation. In some workload, adding the threshold improves virtual memory usage by >10x.
2017-11-10 05:51:39 +08:00
TEST_MALLCTL_OPT(size_t, lg_extent_max_active_fit, always);

Add opt.thp which allows explicit hugepage usage. "always" marks all user mappings as MADV_HUGEPAGE; while "never" marks all mappings as MADV_NOHUGEPAGE. The default setting "default" does not change any settings. Note that all the madvise calls are part of the default extent hooks by design, so that customized extent hooks have complete control over the mappings including hugepage settings.

Split decay-based purging into two phases, the first of which uses lazy purging to convert dirty pages to "muzzy", and the second of which uses forced purging, decommit, or unmapping to convert pages to clean or destroy them altogether. Not all operating systems support lazy purging, yet the application may provide extent hooks that implement lazy purging, so care must be taken to dynamically omit the first phase when necessary.

Guard prof related mallctl with opt_prof. The prof initialization is done only when opt_prof is true. This change makes sure the prof_* mallctls only have limited read access (i.e. no access to prof internals) when opt_prof is false. In addition, initialize the global prof mutexes even if opt_prof is false. This makes sure the mutex stats are set properly.
