* Make Emscripten Asyncify feature optionalJukka Jylanki2022-11-241-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue #506 (bdwgc). "-sASYNCIFY" is a relatively rarely used feature of Emscripten, most developers do not use it, and it does not scale well to moderate-to-large codebases. It incurs a heavy impact to code size and performance, and carries other correctness problems that developers must then adhere to regarding event loop message ordering. This commit provides new option in cmake (-Denable_emscripten_asyncify) and configure (--enable-emscripten-asyncify) scripts to turn on Emscripten Asyncify feature on demand. * CMakeLists.txt (enable_emscripten_asyncify): New option (off by default). * CMakeLists.txt (EMSCRIPTEN): Define using check_c_source_compiles. * CMakeLists.txt [EMSCRIPTEN && enable_emscripten_asyncify] (EMSCRIPTEN_ASYNCIFY): Define C macro. * CMakeLists.txt [EMSCRIPTEN && enable_emscripten_asyncify] (CMAKE_EXE_LINKER_FLAGS): Append "-sASYNCIFY" and "-sASYNCIFY_STACK_SIZE=128000". * configure.ac (emscripten): Remove quotes for the error directive message. * configure.ac [emscripten] (gc_cflags): Move comment and assignment down (to be after reporting result for emscripten). * configure.ac (emscripten-asyncify): New AC_ARG_ENABLE option; add comment. * configure.ac [enable_emscripten_asyncify && emscripten] (gc_cflags): Add -D EMSCRIPTEN_ASYNCIFY; remove space after "-s". * configure.ac [emscripten] (gc_cflags): Append "-sASYNCIFY" and "-sASYNCIFY_STACK_SIZE=128000" only if enable_emscripten_asyncify. * doc/README.macros (EMSCRIPTEN_ASYNCIFY): Document. * os_dep.c [!ECOS && !NOSYS && !SYMBIAN && EMSCRIPTEN]: Make USE_EMSCRIPTEN_SCAN_STACK has effect only if EMSCRIPTEN_ASYNCIFY. * os_dep.c [THREADS && EMSCRIPTEN]: Include emscripten.h only if EMSCRIPTEN_ASYNCIFY. * os_dep.c [THREADS && EMSCRIPTEN] (scan_regs_cb, GC_default_push_other_roots): Define as a function only if EMSCRIPTEN_ASYNCIFY; update comment.

* Prevent (fix) parallel custom mark procs run in single-threaded clientsIvan Maidanski2022-06-012-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the collector is built with parallel marker support then marking is performed in parallel on multi-core targets. Thus, if the client provides custom mark procedures, then they could be executed in parallel. In case of a single-threaded client (developed for the older libgc version with the parallel mark support off), its custom mark procedures might not be prepared to be launched in parallel. Now, the parallel mark threads are not launched, even if available, until the client starts a (user) thread (e.g. calls pthread_create or GC_allow_register_threads) or tells the collector explicitly to start the mark threads (by calling GC_start_mark_threads). * doc/README.macros (GC_ALWAYS_MULTITHREADED): Update documentation. * doc/scale.md (Options for enhanced scalability): Likewise. * include/gc/gc.h [GC_THREADS] (GC_parallel, GC_allow_register_threads): Update comment. * include/gc/gc.h (GC_set_markers_count, GC_start_mark_threads): Likewise. * include/gc/gc_mark.h (GC_mark_proc): Likewise. * include/gc/gc_mark.h (GC_PROC_BYTES, GC_ms_entry): Move upper to be before the comment belonging to GC_mark_proc. * misc.c [THREADS && PARALLEL_MARK] (GC_init): Do not call GC_start_mark_threads_inner(). * misc.c [PARALLEL_MARK] (GC_start_mark_threads): Call GC_start_mark_threads_inner() even if THREAD_SANITIZER or no CAN_HANDLE_FORK. * misc.c [THREADS] (GC_get_parallel): Remove comment. * pthread_support.c [PARALLEL_MARK && !CAN_HANDLE_FORK] (available_markers_m1): Define as a variable. * win32_threads.c [PARALLEL_MARK && !CAN_HANDLE_FORK] (available_markers_m1): Likewise. * pthread_support.c [PARALLEL_MARK && !CAN_HANDLE_FORK] (GC_wait_for_gc_completion): Declare. * pthread_support.c [PARALLEL_MARK && !CAN_HANDLE_FORK] (GC_start_mark_threads_inner): If GC_parallel then return; call GC_wait_for_gc_completion(); set GC_markers_m1 value from available_markers_m1. * win32_threads.c [PARALLEL_MARK && (!GC_PTHREADS_PARAMARK || !CAN_HANDLE_FORK)] (GC_start_mark_threads_inner): Likewise. * pthread_support.c [CAN_HANDLE_FORK && PARALLEL_MARK && THREAD_SANITIZER] (fork_child_proc): Set available_markers_m1 to 0. * pthread_support.c [CAN_HANDLE_FORK]: Move GC_remove_all_threads_but_me() call to be after setting available_markers_m1. * pthread_support.c (GC_allow_register_threads): Call GC_start_mark_threads(). * tests/middle.c (main): Likewise. * win32_threads.c (GC_allow_register_threads): Likewise. * pthread_support.c [PARALLEL_MARK] (pthread_create): Call GC_start_mark_threads() unless GC_parallel or available_markers_m1<=0. * win32_threads.c (START_MARK_THREADS): Define macro (to call GC_start_mark_threads() if PARALLEL_MARK). * win32_threads.c (GC_CreateThread): Call START_MARK_THREADS() (right before set_need_to_lock). * win32_threads.c [!CYGWIN32 && !MSWINCE && !MSWIN_XBOX1 && !NO_CRT] (GC_beginthreadex): Likewise. * win32_threads.c [GC_PTHREADS] (GC_pthread_create): Likewise.

* Do not hard-code finalizable objects limit which triggers GCIvan Maidanski2020-07-311-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue #304 (bdwgc). Previously, if more than 500 finalizable objects emerged since the latest collection (and the incremental mode is off), then new collection is started instead heap expansion. This led to frequent collections if most allocated objects were with a registered finalizer. Now, the hard coded limit (500) is replaced roughly with (GC_bytes_allocd / GC_allocd_bytes_per_finalizer), where the latter global variable has the default value of 10000 (or GC_ALLOCD_BYTES_PER_FINALIZER if defined) but could be changed by the client with GC_set_allocd_bytes_per_finalizer(). * alloc.c (GC_allocd_bytes_per_finalizer): New STATIC variable (initialized to GC_ALLOCD_BYTES_PER_FINALIZER if defined otherwise to 10000). * alloc.c (GC_set_allocd_bytes_per_finalizer, GC_get_allocd_bytes_per_finalizer): New API function definition. * alloc.c (GC_collect_or_expand): Replace GC_fo_entries>last_fo_entries+500 condition to GC_fo_entries>last_fo_entries && (GC_fo_entries-last_fo_entries)*GC_allocd_bytes_per_finalizer >GC_bytes_allocd. * doc/README.macros (GC_ALLOCD_BYTES_PER_FINALIZER): Document. * include/gc.h (GC_set_allocd_bytes_per_finalizer, GC_get_allocd_bytes_per_finalizer): New API function declaration. * include/gc.h (GC_INIT_CONF_ALLOCD_BYTES_PER_FINALIZER): New internal macro (call GC_set_allocd_bytes_per_finalizer if GC_ALLOCD_BYTES_PER_FINALIZER is defined by client). * include/gc.h (GC_INIT): Call GC_INIT_CONF_ALLOCD_BYTES_PER_FINALIZER. * tests/test.c [!PCR && !GC_WIN32_THREADS && !GC_PTHREADS && CPPCHECK] (main): Call UNTESTED() for GC_get_allocd_bytes_per_finalizer and GC_set_allocd_bytes_per_finalizer.
