| | | | | | * mark_rts.c [DEBUG_ADD_DEL_ROOTS] (GC_clear_exclusion_table, GC_exclude_static_roots_inner): Call GC_log_printf() to report update GC_excl_table[].
* Allow GC_push_roots to work even when no exclusions registeredIvan Maidanski2023-05-161-21/+17
| | | | | | | | | | | | Also, includes minor code refactoring and reformatting of GC_exclude_static_roots_inner and GC_push_conditional_with_exclusions. * mark_rts.c (GC_next_exclusion): Update comment; return NULL if GC_excl_table_entries is zero (instead of assertion violation). * mark_rts.c (GC_exclude_static_roots_inner): Call GC_next_exclusion() unconditionally. * mark_rts.c (GC_push_conditional_with_exclusions): Refactor code to have GC_PUSH_CONDITIONAL() call in a single place.
* Fix GC_excl_table overrun on overflow in GC_exclude_static_rootsIvan Maidanski2023-05-161-7/+9
| | | | | | | | | | | Previously, in case of full GC_excl_table[], an attempt to insert an element to it caused write past end of GC_excl_table (when shifting the tail elements) before aborting cause of the table overflow. * mark_rts.c (GC_exclude_static_roots_inner): Move check of GC_excl_table_entries upper to be before first access to GC_excl_table; move i local variable down to be near place of usage; cast result of next-GC_excl_table to size_t.

* Fix comparisons to heap boundary in GC_get_back_ptr_info and GC_mark_fromIvan Maidanski2023-05-135-17/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The region delimited by GC_least_plausible_heap_addr and GC_greatest_plausible_heap_addr might contain part of static data roots or stacks (in addition to potential heap expansion areas). Certain comparisons in GC_get_back_ptr_info (when ALIGNMENT is 1) and in GC_mark_from (in assertions) expect the real heap boundaries. * alloc.c [SET_REAL_HEAP_BOUNDS] (GC_add_to_heap): Update GC_least_real_heap_addr and GC_greatest_real_heap_addr variables. * dbg_mlc.c [KEEP_BACK_PTRS && ALIGNMENT == 1] (GC_get_back_ptr_info): Compare alternate_target and target to GC_least_real_heap_addr and GC_greatest_real_heap_addr (instead of GC_least_plausible_heap_addr and GC_greatest_plausible_heap_addr). * include/gc/gc_mark.h (GC_greatest_plausible_heap_addr): Refine comment. * include/private/gc_priv.h [GC_ASSERTIONS || KEEP_BACK_PTRS && ALIGNMENT == 1] (SET_REAL_HEAP_BOUNDS): Define macro. * include/private/gc_priv.h [GC_ASSERTIONS || KEEP_BACK_PTRS && ALIGNMENT == 1] (GC_least_real_heap_addr, GC_greatest_real_heap_addr): Define (as macro). * include/private/gc_priv.h [GC_ASSERTIONS || KEEP_BACK_PTRS && ALIGNMENT == 1] (_GC_arrays._least_real_heap_addr, _GC_arrays._greatest_real_heap_addr): New field; add comment. * mark.c (GC_mark_from): Use GC_greatest_real_heap_addr and GC_least_real_heap_addr instead of GC_least_plausible_heap_addr and GC_greatest_plausible_heap_addr, respectively, in assertions.
* Fix assertion in GC_mark_from regarding GC_least_plausible_heap_addrIvan Maidanski2023-05-121-5/+6
| | | | | | | (fix of commit b21b53a35) * mark.c (GC_mark_from): Allow current_p (p->mse_start) plus descr to be equal to GC_least_plausible_heap_addr in assertion; add comment.

* Travis CI: Test single signal usage for world suspend/resume on Ubuntu/x64Ivan Maidanski2023-05-091-1/+1
|
* Allow single signal usage for both world suspend and resume in gctestIvan Maidanski2023-05-091-1/+5
| | | | | | | | | | By default, 2 distinct signals are used for suspend and resume of the world except for platforms where the signal context is not used. * tests/gctest.c [GC_PTHREADS] (main): Move GC_set_suspend_signal() call to be before GC_COND_INIT() one. * tests/gctest.c [GC_PTHREADS && TEST_REUSE_SIG_SUSPEND] (main): Pass value of GC_get_thr_restart_signal() to GC_set_suspend_signal().

| | | | | | | (fix of commit 2bcec83b6) * include/private/gcconfig.h [(MSWIN32 || MSWINCE) && CPPCHECK] (DATAEND): Do not define to empty.
* Remove code duplication in gcconfig.h for HurdIvan Maidanski2023-05-081-23/+21
| | | | | | | | | (refactoring) * include/private/gcconfig.h [HURD && (I386 || X86_64)] (OS_TYPE, HEURISTIC2, SEARCH_FOR_DATA_START, DATAEND, DYNAMIC_LOADING, USE_MMAP_ANON): Move defintion to common place. * include/private/gcconfig.h [HURD] (MPROTECT_VDB): Add TODO item.

* Workaround a malfunction of soft-dirty bits clearing on Power9Ivan Maidanski2023-05-041-16/+30
| | | | | | | | | | | | | | | | | | (fix of commit c1bf1b973) Issue #479 (bdwgc). Make a page dirty twice in detect_soft_dirty_supported() clearing all the soft-dirty bits in the middle. If the 2nd write to a page is not noticeable, then fallback to mprotect-based VDB. This a workaround for a bug observed, at least, in Fedora 36 kernel on Power9 CPU. * os_dep.c [SOFT_VDB] (clear_soft_dirty_bits): New static function (move part of code from GC_soft_read_dirty). * os_dep.c [SOFT_VDB] (detect_soft_dirty_supported): Call clear_soft_dirty_bits() and retry changing *vaddr to check whether the latter is reflected in pagemap file; add comment. * os_dep.c [SOFT_VDB] (GC_soft_read_dirty): Call clear_soft_dirty_bits.

| | | | | | | | | | | | | | | | | | | | New public function is GC_get_stopped_mark_total_time(). * alloc.c [!NO_CLOCK] (stopped_mark_total_time, stopped_mark_total_ns_frac): New static variable. * alloc.c [!NO_CLOCK] (GC_get_stopped_mark_total_time): New API function definition. * alloc.c [!NO_CLOCK] (GC_stopped_mark): Define start_time_valid, ns_frac_diff local variables; call GET_TIME() also if measure_performance; add TODO item (about code duplication); update stopped_mark_total_time and stopped_mark_total_ns_frac values. * alloc.c (GC_stopped_mark): Move logging of "Marking for collection" upper to be before GET_TIME(start_time). * include/gc/gc.h (GC_get_full_gc_total_time): Refine documentation. * include/gc/gc.h (GC_get_stopped_mark_total_time): New API prototype. * tests/gctest.c [!NO_CLOCK] (check_heap_stats): Call GC_get_stopped_mark_total_time() to report total stopped-world marking time.
* Do not do unnecessary GC_read_dirty() from GC_enable_incrementalIvan Maidanski2023-05-031-3/+8
| | | | | | | | | * misc.c [!GC_DISABLE_INCREMENTAL && !KEEP_BACK_PTRS] (GC_enable_incremental): Do not call GC_read_dirty() if GC_bytes_allocd is non-zero. * misc.c [!GC_DISABLE_INCREMENTAL && !KEEP_BACK_PTRS && !CHECKSUMS] (GC_enable_incremental): Pass TRUE (output_unneeded) to GC_read_dirty().
* More clear message about total duration of full collections in gctestIvan Maidanski2023-05-031-9/+8
| | | | | | * tests/gctest.c [!NO_CLOCK] (check_heap_stats): Print value of GC_get_full_gc_total_time() on a standalone line (and with the proper message).
* Workaround 'condition is always false' cppcheck FP in GC_setpagesizeIvan Maidanski2023-05-031-2/+4
| | | | | | | (fix of commit 3af192338) * os_dep.c [SOFT_VDB] (GC_setpagesize): Do not check that GC_page_size value is a power of two if CPPCHECK.
* Update time statistics about stopped marking even if abandonedIvan Maidanski2023-05-021-53/+41
| | | | | | | | | | | | | | Also, move logging of the message about collection abandoning to the place after the world is resumed. * alloc.c (GC_stopped_mark): Rename i local variable to abandoned_at. * alloc.c [THREADS] (GC_stopped_mark): Remove code duplication regarding GC_world_stopped, GC_on_collection_event and START_WORLD(). * alloc.c [!NO_CLOCK] (GC_stopped_mark): Update world_stopped_total_time and world_stopped_total_divisor even if marking was abandoned. * alloc.c (GC_stopped_mark): Move message about collection abandoning to be after the world is started and GET_TIME(current_time) is called.
* Do not count time spent processing toggle-refs in stopped_markIvan Maidanski2023-05-021-4/+4
| | | | | | | | | Reported world-stopped collection time should not include the time spent in GC_process_togglerefs(). * alloc.c [!GC_NO_FINALIZATION && !GC_TOGGLE_REFS_NOT_NEEDED && !NO_CLOCK] (GC_stopped_mark): Call GC_process_togglerefs() before GET_TIME(start_time).
* Do not use integer division in GC_soft_read_dirtyIvan Maidanski2023-05-021-61/+78
| | | | | | | | | | | | | | | | | | An integer division operation might be slow on some CPU architectures. It should be replaced with a shift operation where possible. The SOFT_VDB algorithm used division and multiplication by the page size. * os_dep.c [SOFT_VDB] (GC_log_pagesize): Define STATIC variable. * os_dep.c (GC_setpagesize): Define in a single place (for Win32 and non-Win32 cases). * os_dep.c [SOFT_VDB] (os2_getpagesize): Define pgsize and log_pgsize local variables; compute GC_log_pagesize value. * os_dep.c [SOFT_VDB] (detect_soft_dirty_supported, soft_set_grungy_pages): Check GC_log_pagesize instead of GC_page_size in assertion; use shift by GC_log_pagesize instead of division (and multiplication) by GC_page_size. * os_dep.c [SOFT_VDB] (pagemap_buffered_read): Add assertion that GC_page_size is non-zero.

| | | | | | | | | (fix of commits 4240cfb99, 68d419a51) * pthread_support.c [!DONT_USE_ATEXIT] (GC_is_main_thread): Use THREAD_ID_EQUAL() to compare GC_main_thread_id value. * pthread_support.c [!GC_NO_THREADS_DISCOVERY && GC_WIN32_THREADS] (GC_unregister_my_thread): Likewise.
* Fix missing cast of typed calloc result in gctestIvan Maidanski2023-04-271-1/+2

* Travis CI: Fall back to Focal and Xenial for some builds with TSanIvan Maidanski2023-04-271-4/+5
| | | | This is temporary until Thread sanitizer deadlock issues are resolved.
* Suppress a data race report in debug-related GC_n_set_marksIvan Maidanski2023-04-271-0/+3
| | | | | | | | There could be a race between GC_clear_hdr_marks and GC_n_set_marks but the latter is for a debug purpose. * reclaim.c [USE_MARK_BYTES] (GC_n_set_marks): Add GC_ATTR_NO_SANITIZE_THREAD attribute; update comment.
* Eliminate data race FP between remove_protection and write_fault_handlerIvan Maidanski2023-04-271-1/+17
| | | | | | | | | * os_dep.c [MPROTECT_VDB] (get_pht_entry_from_index_async): Define (as a static function with GC_ATTR_NO_SANITIZE_THREAD or as a macro); add comment. * os_dep.c [!GC_DISABLE_INCREMENTAL && MPROTECT_VDB] (GC_remove_protection): Call get_pht_entry_from_index_async() instead of get_pht_entry_from_index().
* Fix unused GC_parse_version if no SOFT_VDB and no parallel mark on LinuxIvan Maidanski2023-04-262-2/+2
| | | | | | | | | | (fix of commit 6e1b82b0a) * include/private/gc_priv.h [GLIBC_2_19_TSX_BUG && THREADS] (GC_parse_version): Do not declare unless GC_PTHREADS_PARAMARK. * os_dep.c [(!SOFT_VDB || NO_SOFT_VDB_LINUX_VER_RUNTIME_CHECK) && GLIBC_2_19_TSX_BUG && THREADS] (GC_parse_version): Do not define unless GC_PTHREADS_PARAMARK.
* New API for more optimal usage of GC_calloc_explicitly_typedIvan Maidanski2023-04-263-18/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the client needs to allocate many typed object arrays of same layout and amount of elements, then "calloc" descriptor could be created once (by GC_calloc_prepare_explicitly_typed) followed by multiple allocations (by GC_calloc_do_explicitly_typed) referring to the same descriptor. * include/gc/gc_typed.h (GC_CALLOC_TYPED_DESCR_WORDS): New macro. * include/gc/gc_typed.h (GC_calloc_typed_descr_s): New struct type. * include/gc/gc_typed.h (GC_calloc_prepare_explicitly_typed, GC_calloc_do_explicitly_typed): New function declaration. * tests/gctest.c [!NO_TYPED_TEST && !GC_DEBUG] (typed_test): Define ctd_l local variable; call GC_calloc_prepare_explicitly_typed() before loop; call GC_calloc_do_explicitly_typed() instead of GC_CALLOC_EXPLICITLY_TYPED(1001). * typd_mlc.c (GC_calloc_typed_descr_s.alloc_lb): Change type from size_t to word. * typd_mlc.c (GC_calloc_typed_descr_s.descr_type): Change type from int to signed_word. * typd_mlc.c (GC_calloc_prepare_explicitly_typed, GC_calloc_do_explicitly_typed): Change from STATIC to GC_API; add ctd_sz argument; check ctd_sz in assertion; add casts for alloc_lb field. * typd_mlc.c (GC_calloc_prepare_explicitly_typed): Add static assertion about size of GC_calloc_typed_descr_s and GC_CALLOC_TYPED_DESCR_WORDS; change return type from void to it. * typd_mlc.c (GC_calloc_explicitly_typed): Pass sizeof(ctd) to GC_calloc_prepare_explicitly_typed(), GC_calloc_do_explicitly_typed().
* Decouple descriptor compute from object alloc in calloc_explicitly_typedIvan Maidanski2023-04-261-36/+70
| | | | | | | | | | | | | | | | | | | (refactoring) This is a preparation for providing ability to the client to compute (and allocate) the internal descriptor of GC_calloc_explicitly_typed once (for the given object layout and elements count) and perform the typed allocation multiple times. * typd_mlc.c (GC_calloc_typed_descr_s): New struct type. * typd_mlc.c (GC_calloc_prepare_explicitly_typed, GC_calloc_do_explicitly_typed): New static function (move part of code from GC_calloc_explicitly_typed); use GC_calloc_typed_descr_s to pass leaf, simple_d, complex_d, alloc_lb, descr_type values between two functions; set and use alloc_lb instead of updating lb local variable. * typd_mlc.c (GC_calloc_explicitly_typed): Use GC_calloc_prepare_explicitly_typed and GC_calloc_do_explicitly_typed. * typd_mlc.c (GC_array_mark_proc): Update comment.
* Invoke GC_oom_fn if GC_make_array_descriptor failed because of no memoryIvan Maidanski2023-04-251-1/+1
| | | | | * typd_mlc.c (GC_calloc_explicitly_typed): If descr_type is NO_MEM then return the result of GC_get_oom_fn()(lb).
* Travis CI: Randomly choose CPU core for tests with AO ops emulationIvan Maidanski2023-04-251-3/+3
|
* Allow to randomly choose a CPU core if AO ops are emulated with locksIvan Maidanski2023-04-251-0/+13
| | | | | | | | | | | | This is needed for test purpose to have all test processes to run on different CPU cores (even if each process occupies just one core). * pthread_support.c [!GC_WIN32_THREADS && BASE_ATOMIC_OPS_EMULATED && SIGNAL_BASED_STOP_WORLD && RANDOM_ONE_CPU_CORE] (GC_thr_init): Define and set cpu_highest_set variable; update cpu_lowest_set based getpid() and cpu_highest_set values (so that to have cpu_lowest_set randomly set between lowest and highest set bits in the mask); add comment.
* Do incremental mark some in GC_collect_a_little even if GC is disabledIvan Maidanski2023-04-253-10/+11
| | | | | | | | | | | | | | | | | | | | Previous behavior was not documented but this API function did nothing in this case. That might cause a deadlock in the client code if the incremental collection was ongoing and the client called GC_collect_a_little() repeatedly (while the result is true). The new behavior, for the cause of disabled garbage collection, is to perform some amount of marking if the incremental collection is ongoing (but not stopping the world and, thus, not causing the memory reclaim to start), returning true if there is something more to mark. * alloc.c (GC_try_to_collect_inner): Change a loop to do-while one. * alloc.c (GC_collect_a_little): Do not check GC_dont_gc (i.e. call GC_collect_a_little_inner() unconditionally); add comment. * include/gc/gc.h (GC_collect_a_little): Update comment (describe the case when GC is disabled). * tests/gctest.c (check_heap_stats): Do not call GC_is_disabled(); add comment.
* Fix infinite loop in disable_gc_for_dlopen and GC_wait_for_gc_completionIvan Maidanski2023-04-252-13/+17
