* Mask signals during background thread creation.Jason Evans2017-06-211-0/+1
| | | | | This prevents signals from being inadvertently delivered to background threads.
* Refactor *decay_time into *decay_ms.Jason Evans2017-05-181-0/+3
| | | | | | | | 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.
* Use openat syscall if availableJim Chen2017-04-211-0/+5
| | | | | | | | | | Some architectures like AArch64 may not have the open syscall because it was superseded by the openat syscall, so check and use SYS_openat if SYS_open is not available. Additionally, Android headers for AArch64 define SYS_open to __NR_open, even though __NR_open is undefined. Undefine SYS_open in that case so SYS_openat is used.
* Replace tabs following #define with spaces.Jason Evans2017-01-211-1/+1
| | | | This resolves #564.
* Update brace style.Jason Evans2017-01-211-2/+1
| | | | | | | Add braces around single-line blocks, and remove line breaks before function-opening braces. This resolves #537.
* Remove leading blank lines from function bodies.Jason Evans2017-01-131-1/+0
| | | | This resolves #535.
* Add os_unfair_lock support.Jason Evans2016-11-031-0/+3
| | | | | OS X 10.12 deprecated OSSpinLock; os_unfair_lock is the recommended replacement.
* Support static linking of jemalloc with glibcDave Watson2016-10-281-0/+3
| | | | | | | | | | | | | | | | | | | | | | | glibc defines its malloc implementation with several weak and strong symbols: strong_alias (__libc_calloc, __calloc) weak_alias (__libc_calloc, calloc) strong_alias (__libc_free, __cfree) weak_alias (__libc_free, cfree) strong_alias (__libc_free, __free) strong_alias (__libc_free, free) strong_alias (__libc_malloc, __malloc) strong_alias (__libc_malloc, malloc) The issue is not with the weak symbols, but that other parts of glibc depend on __libc_malloc explicitly. Defining them in terms of jemalloc API's allows the linker to drop glibc's malloc.o completely from the link, and static linking no longer results in symbol collisions. Another wrinkle: jemalloc during initialization calls sysconf to get the number of CPU's. GLIBC allocates for the first time before setting up isspace (and other related) tables, which are used by sysconf. Instead, use the pthread API to get the number of CPUs with GLIBC, which seems to work. This resolves #442.
* Refine nstime_update().Jason Evans2016-10-101-0/+4
| | | | | | | | | | | | | | | | | | | | | Add missing #include <time.h>. The critical time facilities appear to have been transitively included via unistd.h and sys/time.h, but in principle this omission was capable of having caused clock_gettime(CLOCK_MONOTONIC, ...) to have been overlooked in favor of gettimeofday(), which in turn could cause spurious non-monotonic time updates. Refactor nstime_get() out of nstime_update() and add configure tests for all variants. Add CLOCK_MONOTONIC_RAW support (Linux-specific) and mach_absolute_time() support (OS X-specific). Do not fall back to clock_gettime(CLOCK_REALTIME, ...). This was a fragile Linux-specific workaround, which we're unlikely to use at all now that clock_gettime(CLOCK_MONOTONIC_RAW, ...) is supported, and if we have no choice besides non-monotonic clocks, gettimeofday() is only incrementally worse.
* Fix Windows build issuesDmitri Smirnov2016-02-241-2/+1
| | | | This resolves #333.
* Remove _WIN32-specific struct timespec declaration.Jason Evans2016-02-211-6/+0
| | | | struct timespec is already defined by the system (at least on MinGW).
* Add time_update().Cameron Evans2016-02-201-0/+8

* MSVC compatibility changesMatthijs2015-08-041-0/+3
| | | | | | - Decorate public function with __declspec(allocator) and __declspec(restrict), just like MSVC 1900 - Support JEMALLOC_HAS_RESTRICT by defining the restrict keyword - Move __declspec(nothrow) between 'void' and '*' so it compiles once more
* Fix MinGW-related portability issues.Jason Evans2015-07-231-31/+2
| | | | | | | | | | | | | Create and use FMT* macros that are equivalent to the PRI* macros that inttypes.h defines. This allows uniform use of the Unix-specific format specifiers, e.g. "%zu", as well as avoiding Windows-specific definitions of e.g. PRIu64. Add ffs()/ffsl() support for compiling with gcc. Extract compatibility definitions of ENOENT, EINVAL, EAGAIN, EPERM, ENOMEM, and ENORANGE into include/msvc_compat/windows_extra.h and use the file for tests as well as for core jemalloc code.
* Fix MinGW build warnings.Jason Evans2015-07-081-8/+30
| | | | | | | | | | Conditionally define ENOENT, EINVAL, etc. (was unconditional). Add/use PRIzu, PRIzd, and PRIzx for use in malloc_printf() calls. gcc issued (harmless) warnings since e.g. "%zu" should be "%Iu" on Windows, and the alternative to this workaround would have been to disable the function attributes which cause gcc to look for type mismatches in formatted printing function calls.

* Try to use __builtin_ffsl if ffsl is unavailable.Richard Diamond2014-06-021-4/+6
| | | | | | | | | | | Some platforms (like those using Newlib) don't have ffs/ffsl. This commit adds a check to configure.ac for __builtin_ffsl if ffsl isn't found. __builtin_ffsl performs the same function as ffsl, and has the added benefit of being available on any platform utilizing Gcc-compatible compiler. This change does not address the used of ffs in the MALLOCX_ARENA() macro.
