Implement configuration system. Implement minimal Makefile. Make compile-time-optional jemalloc features controllable via configure options (debug, stats, tiny, mag, balance, dss). Conditionally exclude most of the opt_* run-time options, based on configure options (fill, xmalloc, sysv). Implement optional --enable-dynamic-page-shift. Implement optional --enable-lazy-lock. Re-order malloc_init_hard() and use the malloc_initializer variable to support recursive allocation in malloc_ncpus(). Add mag_rack_tsd in order to receive notifications of thread termination. Add jemalloc.h.

Add initial support for building with the cray compiler Get jemalloc building and passing `make check_unit` with cray 8.4. An inlining bug in 8.4 results in internal errors while trying to build jemalloc. This has already been reported and fixed for the 8.5 release. In order to work around the inlining bug, disable gnu compatibility and limit ipa optimizations. I copied the msvc compiler check for cray, but note that we perform the test even if we think we're using gcc because cray pretends to be gcc if `-hgnu` (which is enabled by default) is used. I couldn't come up with a principled way to check for the inlining bug, so instead I just checked compiler versions. The build had lots of warnings I need to address and cray doesn't support -MM or -MT for dependency tracking, so I had to do `make CC_MM=`.

Add -dynamic for integration and stress tests with Cray compiler wrappers Cray systems come with compiler wrappers to simplify building parallel applications. CC is the C++ wrapper, and cc is the C wrapper. The wrappers call the base {Cray, Intel, PGI, or GNU} compiler with vendor specific flags. The "Programming Environment" (prgenv) that's currently loaded determines the base compiler. e.g. compiling with gnu looks something like: module load PrgEnv-gnu cc hello.c On most systems the wrappers defaults to `-static` mode, which causes them to only look for static libraries, and not for any dynamic ones (even if the dynamic version was explicitly listed.) The integration and stress tests expect to be using the .so, so we have to run the with -dynamic so that wrapper will find/use the .so.

Use bitmaps to track small regions. The previous free list implementation, which embedded singly linked lists in available regions, had the unfortunate side effect of causing many cache misses during thread cache fills. Fix this in two places: - arena_run_t: Use a new bitmap implementation to track which regions are available. Furthermore, revert to preferring the lowest available region (as jemalloc did with its old bitmap-based approach). - tcache_t: Move read-only tcache_bin_t metadata into tcache_bin_info_t, and add a contiguous array of pointers to tcache_t in order to track cached objects. This substantially increases the size of tcache_t, but results in much higher data locality for common tcache operations. As a side benefit, it is again possible to efficiently flush the least recently used cached objects, so this change changes flushing from MRU to LRU. The new bitmap implementation uses a multi-level summary approach to make finding the lowest available region very fast. In practice, bitmaps only have one or two levels, though the implementation is general enough to handle extremely large bitmaps, mainly so that large page sizes can still be entertained. Fix tcache_bin_flush_large() to always flush statistics, in the same way that tcache_bin_flush_small() was recently fixed. Use JEMALLOC_DEBUG rather than NDEBUG. Add dassert(), and use it for debug-only asserts.

Attempts to force SSE2 compilation on a 32-bit Ubuntu 13.10 system running as a VMware guest resulted in a no-win choice without any obvious explanation besides toolchain misconfiguration/bug: - Suffer compilation failure due to __MMX__, __SSE__, and __SSE2__ not being defined, even if -mmmx, -msse, and -msse2 are manually specified (note that they appear to be enabled by default). - Manually define __MMX__, __SSE__, and __SSE2__, and suffer compiler warnings that they are already automatically defined. This results in successful compilation and execution, but the noise is intolerable.

Add -dynamic for integration and stress tests with Cray compiler wrappers Cray systems come with compiler wrappers to simplify building parallel applications. CC is the C++ wrapper, and cc is the C wrapper. The wrappers call the base {Cray, Intel, PGI, or GNU} compiler with vendor specific flags. The "Programming Environment" (prgenv) that's currently loaded determines the base compiler. e.g. compiling with gnu looks something like: module load PrgEnv-gnu cc hello.c On most systems the wrappers defaults to `-static` mode, which causes them to only look for static libraries, and not for any dynamic ones (even if the dynamic version was explicitly listed.) The integration and stress tests expect to be using the .so, so we have to run the with -dynamic so that wrapper will find/use the .so.

Reduce cpp conditional logic complexity. Convert configuration-related cpp conditional logic to use static constant variables, e.g.: #ifdef JEMALLOC_DEBUG [...] #endif becomes: if (config_debug) { [...] } The advantage is clearer, more concise code. The main disadvantage is that data structures no longer have conditionally defined fields, so they pay the cost of all fields regardless of whether they are used. In practice, this is only a minor concern; config_stats will go away in an upcoming change, and config_prof is the only other major feature that depends on more than a few special-purpose fields.

Refine nstime_update(). 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.

Refine nstime_update(). 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.

Add -dynamic for integration and stress tests with Cray compiler wrappers Cray systems come with compiler wrappers to simplify building parallel applications. CC is the C++ wrapper, and cc is the C wrapper. The wrappers call the base {Cray, Intel, PGI, or GNU} compiler with vendor specific flags. The "Programming Environment" (prgenv) that's currently loaded determines the base compiler. e.g. compiling with gnu looks something like: module load PrgEnv-gnu cc hello.c On most systems the wrappers defaults to `-static` mode, which causes them to only look for static libraries, and not for any dynamic ones (even if the dynamic version was explicitly listed.) The integration and stress tests expect to be using the .so, so we have to run the with -dynamic so that wrapper will find/use the .so.

Conditionally exclude most of the opt_* run-time options, based on configure options (fill, xmalloc, sysv). Implement optional --enable-dynamic-page-shift. Implement optional --enable-lazy-lock. Re-order malloc_init_hard() and use the malloc_initializer variable to support recursive allocation in malloc_ncpus(). Add mag_rack_tsd in order to receive notifications of thread termination. Add jemalloc.h.

Fix AC_PATH_PROG() calls to specify default. Fix AC_PATH_PROG() calls to specify 'false' as the default, so that if the configure script fails to find a program, the false program is instead called, and an error occurs. Prior to this fix, if xsltproc could not be found, make would not report an error due to the leading -o in the xsltproc invocation. Reported by David Reiss.

Add support for sized deallocation. This adds a new `sdallocx` function to the external API, allowing the size to be passed by the caller. It avoids some extra reads in the thread cache fast path. In the case where stats are enabled, this avoids the work of calculating the size from the pointer. An assertion validates the size that's passed in, so enabling debugging will allow users of the API to debug cases where an incorrect size is passed in. The performance win for a contrived microbenchmark doing an allocation and immediately freeing it is ~10%. It may have a different impact on a real workload. Closes #28

Refactor to support more varied testing. Refactor the test harness to support three types of tests: - unit: White box unit tests. These tests have full access to all internal jemalloc library symbols. Though in actuality all symbols are prefixed by jet_, macro-based name mangling abstracts this away from test code. - integration: Black box integration tests. These tests link with the installable shared jemalloc library, and with the exception of some utility code and configure-generated macro definitions, they have no access to jemalloc internals. - stress: Black box stress tests. These tests link with the installable shared jemalloc library, as well as with an internal allocator with symbols prefixed by jet_ (same as for unit tests) that can be used to allocate data structures that are internal to the test code. Move existing tests into test/{unit,integration}/ as appropriate. Split out internal parts of jemalloc_defs.h.in and put them in jemalloc_internal_defs.h.in. This reduces internals exposure to applications that #include <jemalloc/jemalloc.h>. Refactor jemalloc.h header generation so that a single header file results, and the prototypes can be used to generate jet_ prototypes for tests. Split jemalloc.h.in into multiple parts (jemalloc_defs.h.in, jemalloc_macros.h.in, jemalloc_protos.h.in, jemalloc_mangle.h.in) and use a shell script to generate a unified jemalloc.h at configure time.

Though in actuality all symbols are prefixed by jet_, macro-based name mangling abstracts this away from test code. - integration: Black box integration tests.

Disable floating point code/linking when possible. Unless heap profiling is enabled, disable floating point code and don't link with libm. This, in combination with e.g. EXTRA_CFLAGS=-mno-sse on x64 systems, makes it possible to completely disable floating point register use. Some versions of glibc neglect to save/restore caller-saved floating point registers during dynamic lazy symbol loading, and the symbol loading code uses whatever malloc the application happens to have linked/loaded with, the result being potential floating point register corruption.

Fix librt detection when using a Cray compiler wrapper The Cray compiler wrappers will often add `-lrt` to the base compiler with `-static` linking (the default at most sites.) However, `-lrt` isn't automatically added with `-dynamic`. This means that if jemalloc was built with `-static`, but then used in a program with `-dynamic` jemalloc won't have detected that librt is a dependency. The integration and stress tests use -dynamic, which is causing undefined references to clock_gettime(). This just adds an extra check for librt (ignoring the autoconf cache) with `-dynamic` thrown. It also stops filtering librt from the integration tests. With this `make check` passes for: - PrgEnv-gnu - PrgEnv-intel - PrgEnv-pgi PrgEnv-cray still needs more work (will be in a separate patch.)

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.

Port to FreeBSD. Use FreeBSD-specific functions (_pthread_mutex_init_calloc_cb(), _malloc_{pre,post}fork()) to avoid bootstrapping issues due to allocation in libc and libthr. Add malloc_strtoumax() and use it instead of strtoul(). Disable validation code in malloc_vsnprintf() and malloc_strtoumax() until jemalloc is initialized. This is necessary because locale initialization causes allocation for both vsnprintf() and strtoumax(). Force the lazy-lock feature on in order to avoid pthread_self(), because it causes allocation. Use syscall(SYS_write, ...) rather than write(...), because libthr wraps write() and causes allocation. Without this workaround, it would not be possible to print error messages in malloc_conf_init() without substantially reworking bootstrapping. Fix choose_arena_hard() to look at how many threads are assigned to the candidate choice, rather than checking whether the arena is uninitialized. This bug potentially caused more arenas to be initialized than necessary.

Refactor to support more varied testing. Refactor the test harness to support three types of tests: - unit: White box unit tests. These tests have full access to all internal jemalloc library symbols. Though in actuality all symbols are prefixed by jet_, macro-based name mangling abstracts this away from test code. - integration: Black box integration tests. These tests link with the installable shared jemalloc library, and with the exception of some utility code and configure-generated macro definitions, they have no access to jemalloc internals. - stress: Black box stress tests. These tests link with the installable shared jemalloc library, as well as with an internal allocator with symbols prefixed by jet_ (same as for unit tests) that can be used to allocate data structures that are internal to the test code. Move existing tests into test/{unit,integration}/ as appropriate. Split out internal parts of jemalloc_defs.h.in and put them in jemalloc_internal_defs.h.in. This reduces internals exposure to applications that #include <jemalloc/jemalloc.h>. Refactor jemalloc.h header generation so that a single header file results, and the prototypes can be used to generate jet_ prototypes for tests. Split jemalloc.h.in into multiple parts (jemalloc_defs.h.in, jemalloc_macros.h.in, jemalloc_protos.h.in, jemalloc_mangle.h.in) and use a shell script to generate a unified jemalloc.h at configure time. Change the default private namespace prefix from "" to "je_". Add missing private namespace mangling. Remove hard-coded private_namespace.h. Instead generate it and private_unnamespace.h from private_symbols.txt. Use similar logic for public symbols, which aids in name mangling for jet_ symbols. Add test_warn() and test_fail().

Refactor to support more varied testing. Refactor the test harness to support three types of tests: - unit: White box unit tests. These tests have full access to all internal jemalloc library symbols. Though in actuality all symbols are prefixed by jet_, macro-based name mangling abstracts this away from test code. - integration: Black box integration tests. These tests link with the installable shared jemalloc library, and with the exception of some utility code and configure-generated macro definitions, they have no access to jemalloc internals. - stress: Black box stress tests. These tests link with the installable shared jemalloc library, as well as with an internal allocator with symbols prefixed by jet_ (same as for unit tests) that can be used to allocate data structures that are internal to the test code. Move existing tests into test/{unit,integration}/ as appropriate. Split out internal parts of jemalloc_defs.h.in and put them in jemalloc_internal_defs.h.in. This reduces internals exposure to applications that #include <jemalloc/jemalloc.h>. Refactor jemalloc.h header generation so that a single header file results, and the prototypes can be used to generate jet_ prototypes for tests. Split jemalloc.h.in into multiple parts (jemalloc_defs.h.in, jemalloc_macros.h.in, jemalloc_protos.h.in, jemalloc_mangle.h.in) and use a shell script to generate a unified jemalloc.h at configure time. Change the default private namespace prefix from "" to "je_". Add missing private namespace mangling. Remove hard-coded private_namespace.h. Instead generate it and private_unnamespace.h from private_symbols.txt. Use similar logic for public symbols, which aids in name mangling for jet_ symbols. Add test_warn() and test_fail(). Replace existing exit(1) calls with test_fail() calls.

Fix name mangling for stress tests. Fix stress tests such that testlib code uses the jet_ allocator, but test code uses libjemalloc. Generate jemalloc_{rename,mangle}.h, the former because it's needed for the stress test name mangling fix, and the latter for consistency. As an artifact of this change, some (but not all) definitions related to the experimental API are absent from the headers unless the feature is enabled at configure time.

Refactor iteration in arena_run_first_fit() to use run_quantize{,_first,_next(), and add support for padded large runs. For large allocations that have no specified alignment constraints, compute a pseudo-random offset from the beginning of the first backing page that is a multiple of the cache line size. Under typical configurations with 4-KiB pages and 64-byte cache lines this results in a uniform distribution among 64 page boundary offsets.
