Without this patch, Ruby doesn't show ractor's information when
there is only 1 ractor. However it is hard to read the log when
some ractors are created and terminated. This patch makes to keep
showing ractor's information on multi-ractor mode.
To make some kind of Ractor related extensions, some functions
should be exposed.
* include/ruby/thread_native.h
* rb_native_mutex_*
* rb_native_cond_*
* include/ruby/ractor.h
* RB_OBJ_SHAREABLE_P(obj)
* rb_ractor_shareable_p(obj)
* rb_ractor_std*()
* rb_cRactor
and rm ractor_pub.h
and rename srcdir/ractor.h to srcdir/ractor_core.h
(to avoid conflict with include/ruby/ractor.h)
This commit introduces Ractor mechanism to run Ruby program in
parallel. See doc/ractor.md for more details about Ractor.
See ticket [Feature #17100] to see the implementation details
and discussions.
[Feature #17100]
This commit does not complete the implementation. You can find
many bugs on using Ractor. Also the specification will be changed
so that this feature is experimental. You will see a warning when
you make the first Ractor with `Ractor.new`.
I hope this feature can help programmers from thread-safety issues.
Old gcc (< 5 maybe?) warns that this variable is not initialized:
debug.c: In function 'ruby_debug_log':
debug.c:441:13: warning: 'r' may be used uninitialized in this function [-Wmaybe-uninitialized]
if (r && len < MAX_DEBUG_LOG_MESSAGE_LEN) {
^
I don't know if that is true, but adding "= 0" here must harm no one.
Now you can specify multiple filters for RUBY_DEBUG_LOG output
by RUBY_DEBUG_LOG_FILTER=a,b,c (in this case, logs that the
function name contains a, b or c).
* RUBY_DEBUG_LOG: Logging debug information mechanism
This feature provides a mechanism to store logging information
to a file, stderr or memory space with simple macros.
The following information will be stored.
* (1) __FILE__, __LINE__ in C
* (2) __FILE__, __LINE__ in Ruby
* (3) __func__ in C (message title)
* (4) given string with sprintf format
* (5) Thread number (if multiple threads are running)
This feature is enabled only USE_RUBY_DEBUG_LOG is enabled.
Release version should not enable it.
Running with the `RUBY_DEBUG_LOG` environment variable enables
this feature.
# logging into a file
RUBY_DEBUG_LOG=/path/to/file STDERR
# logging into STDERR
RUBY_DEBUG_LOG=stderr
# logging into memory space (check with a debugger)
# It will help if the timing is important.
RUBY_DEBUG_LOG=mem
RUBY_DEBUG_LOG_FILTER environment variable can specify the fileter string.
If "(3) __func__ in C (message title)" contains the specified string, the
infomation will be stored (example: RUBY_DEBUG_LOG_FILTER=str will enable
only on str related information).
In a MRI source code, you can use the following macros:
* RUBY_DEBUG_LOG(fmt, ...): Above (1) to (4) will be logged.
* RUBY_DEBUG_LOG2(file, line, fmt, ...):
Same as RUBY_DEBUG_LOG(), but (1) will be replaced with given file, line.
Now, rb_call_info contains how to call the method with tuple of
(mid, orig_argc, flags, kwarg). Most of cases, kwarg == NULL and
mid+argc+flags only requires 64bits. So this patch packed
rb_call_info to VALUE (1 word) on such cases. If we can not
represent it in VALUE, then use imemo_callinfo which contains
conventional callinfo (rb_callinfo, renamed from rb_call_info).
iseq->body->ci_kw_size is removed because all of callinfo is VALUE
size (packed ci or a pointer to imemo_callinfo).
To access ci information, we need to use these functions:
vm_ci_mid(ci), _flag(ci), _argc(ci), _kwarg(ci).
struct rb_call_info_kw_arg is renamed to rb_callinfo_kwarg.
rb_funcallv_with_cc() and rb_method_basic_definition_p_with_cc()
is temporary removed because cd->ci should be marked.
Saves comitters' daily life by avoid #include-ing everything from
internal.h to make each file do so instead. This would significantly
speed up incremental builds.
We take the following inclusion order in this changeset:
1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very
first thing among everything).
2. RUBY_EXTCONF_H if any.
3. Standard C headers, sorted alphabetically.
4. Other system headers, maybe guarded by #ifdef
5. Everything else, sorted alphabetically.
Exceptions are those win32-related headers, which tend not be self-
containing (headers have inclusion order dependencies).
Introduce new RUBY_DEBUG option 'ci' to inform Ruby interpreter
that an interpreter is running on CI environment.
With this option, `rb_bug()` shows more information includes
method entry information, local variables information for each
control frame.
* debug.c (ruby_dummy_gdb_enums): force to include struct RSymbol
info.

option same as RUBY_DEBUG env. available only in the trunk.

instead of rb_inspect() because it is more robust way
to see object internal.

This change also introduces the following changes.
* Remove RGENGC_AGE2_PROMOTION and introduce object age (0 to 3).
Age can be count with FL_PROMOTE0 and FL_PROMOTE1 flags in
RBasic::flags (2 bit). Age == 3 objects become old objects.
* WB_PROTECTED flag in RBasic to WB_UNPROTECTED bitmap.
* LONG_LIVED bitmap to represent living objects while minor GCs
It specifies (1) Old objects and (2) remembered shady objects.
* Introduce rb_objspace_t::marked_objects which counts marked
objects in current marking phase. marking count is needed to
introduce incremental marking.
* rename mark related function and sweep related function to
gc_(marks|sweep)_(start|finish|step|rest|continue).
* rename rgengc_report() to gc_report().
* Add obj_info() function to get cstr of object details.
* Add MEASURE_LINE() macro to measure execution time of specific line.
* and many small fixes.
* include/ruby/ruby.h: add flag USE_RINCGC.
Now USE_RINCGC can be set only with USE_RGENGC.
* include/ruby/ruby.h: introduce FL_PROMOTED0 and add FL_PROMOTED1
to count object age.
* include/ruby/ruby.h: rewrite write barriers for incremental marking.
* debug.c: catch up flag name changes.
* internal.h: add rb_gc_writebarrier_remember() instead of
rb_gc_writebarrier_remember_promoted().
* array.c (ary_memcpy0): use rb_gc_writebarrier_remember().
* array.c (rb_ary_modify): ditto.
* hash.c (rb_hash_keys): ditto.
* hash.c (rb_hash_values): ditto.
* object.c (init_copy): use rb_copy_wb_protected_attribute() because
FL_WB_PROTECTED is moved from RBasic::flags.
* test/objspace/test_objspace.rb: catch up ObjectSpace.dump() changes.
