| | | | | | | It seems this breaks tests on Solaris, so I'm reverting it until we figure out the right fix. http://rubyci.s3.amazonaws.com/solaris11-sunc/ruby-master/log/20210224T210007Z.fail.html.gz

* show more information about imemo_mentKoichi Sasada2021-02-191-15/+18
| | | | | rb_obj_info(obj) (rp(obj)) doesn't show enough information for non-iseq methods, so this patch shows more.
* sync check_rvalue_consistency_force()Koichi Sasada2021-02-181-73/+76
| | | | | | check_rvalue_consistency_force() uses is_pointer_to_heap() and it should be synchronized with other ractors. [Bug #17636]
* clear RVALUE on NEWOBJ event.Koichi Sasada2021-02-181-12/+15
| | | | | | NEWOBJ event is called without clearing RVALUE values (v1, v2, v3). This patch clear them before NEWOBJ tracepoint internal hook. [Bug #17599]
* sync GC rest if neededKoichi Sasada2021-02-181-0/+3
| | | | | | marking requires a barrier (stop all Ractors) and gc_enter() does it. However, it doesn't check rest event which can start marking. [Bug #17599]
* Removed no-longer used variableNobuyoshi Nakada2021-02-171-2/+0

* Remove unreachable if statement in gc_page_sweepPeter Zhu2021-02-161-7/+0
| | | | This if statement is not reachable because `was_compacting` cannot be true when `heap->compact_cursor` is NULL.
* Don't register non-heap allocated objectsAaron Patterson2021-02-041-0/+3
| | | | | | | | | | | | | | | | | | | | | | `rb_define_const` can add objects as "mark objects". This is to make code like this work: https://github.com/ruby/ruby/blob/33d6e92e0c6eaf1308ce7108e653c53bb5fb106c/ext/etc/etc.c#L1201 ``` rb_define_const(rb_cStruct, "Passwd", sPasswd); /* deprecated name */ ``` sPasswd is a heap allocated object that is also a C global, so we can't move it (it needs to be pinned). However, we have many calls to `rb_define_const` that just pass in an integer like this: ``` rb_define_const(rb_cDBM, "WRITER", INT2FIX(O_RDWR|RUBY_DBM_RW_BIT)); ``` Non heap allocated objects like integers will never move, so there is no reason to waste time in the GC marking / pinning them.
* Use RCLASS_EXT macro instead of directly accessing ptrMatt Valentine-House2021-02-011-5/+5

* Add RCLASS_SUBCLASSES MacroMatt Valentine-House2021-02-011-4/+4

* Removed static assertion about size of `RVALUE`Nobuyoshi Nakada2021-01-311-2/+0
| | | | | It is unable where unaligned word access is disallowed and `double` is wider than pointers.
* Narrowed down the condition to pack RValueNobuyoshi Nakada2021-01-311-3/+5
| | | | | | Because of `double` in `RFloat`, `RValue` would be packed by `sizeof(double)` by default, on platforms where `double` is wider than `VALUE`. Size of `RValue` is multiple of 5 now.

* Fix RGENGC CHECK MODE >= 4Matt Valentine-House2021-01-261-2/+7
| | | | | | | | [A previous commit](b59077eecf912a16efefc0256f6e94a000ce3888) removes some macro definitions that are used when RGENGC_CHECK_MODE >=4 because they were using data stored against objspace, which is not ractor safe This commit reinstates those macro definitions, using the current ractor Co-authored-by: peterzhu2118 <peter@peterzhu.ca>

* check is_incremental_marking() againKoichi Sasada2021-01-221-1/+10
| | | | | is_incremental_marking() can be changed after checking the flag without locking, especially on `GC.stress = true`.
* Fix more assumptions about the read barrierAaron Patterson2021-01-211-10/+0
| | | | | This is a continuation of 0130e17a410d60a10e7041ce98748b8de6946971. We need to always use the read barrier
* Always enabled read barrier even on GC.compactAaron Patterson2021-01-211-17/+3
| | | | | | | | | | | | Some objects can survive the GC before compaction, but get collected in the second compaction. This means we could have objects reference T_MOVED during "free" in the second, compacting GC. If that is the case, we need to invalidate those "moved" addresses. Invalidation is done via read barrier, so we need to make sure the read barrier is active even during `GC.compact`. This also means we don't actually need to do one GC before compaction, we can just do the compaction and GC in one step.

* enable constant cache on ractorsKoichi Sasada2021-01-051-3/+16
| | | | | | | | | | | | | | | | constant cache `IC` is accessed by non-atomic manner and there are thread-safety issues, so Ruby 3.0 disables to use const cache on non-main ractors. This patch enables it by introducing `imemo_constcache` and allocates it by every re-fill of const cache like `imemo_callcache`. [Bug #17510] Now `IC` only has one entry `IC::entry` and it points to `iseq_inline_constant_cache_entry`, managed by T_IMEMO object. `IC` is atomic data structure so `rb_mjit_before_vm_ic_update()` and `rb_mjit_after_vm_ic_update()` is not needed.
* Stop managing valid class serialsTakashi Kokubun2020-12-291-1/+0
| | | | `mjit_valid_class_serial_p` has no longer been used since b9007b6c548.

* define RGENGC_DEBUG_ENABLED() as 0Koichi Sasada2020-12-251-1/+1
| | | | | | | on RUBY_DEVEL==0 and !HAVE_VA_ARGS_MACRO. gc_report() is always enabled on such configuration (maybe it is a bug) so disable RGENGC_DEBUG_ENABLED().
* Use rb_init_identtable instead of direct use of rb_hashtype_identNobuyoshi Nakada2020-12-231-3/+2

* separate rb_ractor_pub from rb_ractor_tKoichi Sasada2020-12-221-1/+1
| | | | | | | | | separate some fields from rb_ractor_t to rb_ractor_pub and put it at the beggining of rb_ractor_t and declare it in vm_core.h so vm_core.h can access rb_ractor_pub fields. Now rb_ec_ractor_hooks() is a complete inline function and no MJIT related issue.
* finalizing should be checked before VM lockKoichi Sasada2020-12-181-2/+3

* Removed a moved local variableNobuyoshi Nakada2020-12-181-2/+0
|
* need to sync gc_finalize_deferredKoichi Sasada2020-12-181-3/+9
| | | | | gc_finalize_deferred() runs finalizers and it accesses objspace, so it need to sync.
* Removed old GC.stat keys deprecated since 2.2Nobuyoshi Nakada2020-12-181-133/+0

* Removed old GC tuning environment variables deprecated since 2.1Nobuyoshi Nakada2020-12-181-7/+0

* acquire VM lock on gc_verify_internal_consistency()Koichi Sasada2020-12-181-7/+10
| | | | There is a case to call this function without VM lock acquiring.
* add explicit checkKoichi Sasada2020-12-181-2/+2
| | | | | To debug this issue: https://rubyci.org/logs/rubyci.s3.amazonaws.com/solaris10-gcc/ruby-master/log/20201217T220004Z.fail.html.gz
* gc_verify_internal_consistency() needs barrierKoichi Sasada2020-12-181-1/+3
| | | | | gc_verify_internal_consistency() accesses all slots (objects) so all ractors should stop before starting this function.
* sync obj_to_id_tblKoichi Sasada2020-12-171-3/+4
| | | | | objspace->obj_to_id_tbl is a shared table so we need to synchronize it to access.
* reduce barrier counts for GC eventsKoichi Sasada2020-12-171-1/+9
| | | | | mark needs barrier (stop other ractors), but other GC events don't need barriers (maybe...).
* relax synchronization on WBKoichi Sasada2020-12-171-29/+10
| | | | Current synchronization is too much on write barriers.
* add debug counters for gc start eventsKoichi Sasada2020-12-171-22/+59
|
* RGENGC_PROFILE=0Koichi Sasada2020-12-171-1/+1
| | | | Enabled this flag, maybe accidentally.
