* M:N thread scheduler for RactorsKoichi Sasada2023-10-121-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduce M:N thread scheduler for Ractor system. In general, M:N thread scheduler employs N native threads (OS threads) to manage M user-level threads (Ruby threads in this case). On the Ruby interpreter, 1 native thread is provided for 1 Ractor and all Ruby threads are managed by the native thread. From Ruby 1.9, the interpreter uses 1:1 thread scheduler which means 1 Ruby thread has 1 native thread. M:N scheduler change this strategy. Because of compatibility issue (and stableness issue of the implementation) main Ractor doesn't use M:N scheduler on default. On the other words, threads on the main Ractor will be managed with 1:1 thread scheduler. There are additional settings by environment variables: `RUBY_MN_THREADS=1` enables M:N thread scheduler on the main ractor. Note that non-main ractors use the M:N scheduler without this configuration. With this configuration, single ractor applications run threads on M:1 thread scheduler (green threads, user-level threads). `RUBY_MAX_CPU=n` specifies maximum number of native threads for M:N scheduler (default: 8). This patch will be reverted soon if non-easy issues are found. [Bug #19842]

* Revert "Hide most of the implementation of `struct rb_io`. (#6511)"NARUSE, Yui2023-06-011-1/+1
| | | | | | | | | This reverts commit 18e55fc1e1ec20e8f3166e3059e76c885fc9f8f2. fix [Bug #19704] https://bugs.ruby-lang.org/issues/19704 This breaks compatibility for extension libraries. Such changes need a discussion.
* Hide most of the implementation of `struct rb_io`. (#6511)Samuel Williams2023-05-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | * Add rb_io_path and rb_io_open_descriptor. * Use rb_io_open_descriptor to create PTY objects * Rename FMODE_PREP -> FMODE_EXTERNAL and expose it FMODE_PREP I believe refers to the concept of a "pre-prepared" file, but FMODE_EXTERNAL is clearer about what the file descriptor represents and aligns with language in the IO::Buffer module. * Ensure that rb_io_open_descriptor closes the FD if it fails If FMODE_EXTERNAL is not set, then it's guaranteed that Ruby will be responsible for closing your file, eventually, if you pass it to rb_io_open_descriptor, even if it raises an exception. * Rename IS_EXTERNAL_FD -> RUBY_IO_EXTERNAL_P * Expose `rb_io_closed_p`. * Add `rb_io_mode` to get IO mode. --------- Co-authored-by: KJ Tsanaktsidis <ktsanaktsidis@zendesk.com>

* [Feature #19579] Remove !USE_RVARGC code (#7655)Peter Zhu2023-04-041-6/+0
| | | | | | | | | | | Remove !USE_RVARGC code [Feature #19579] The Variable Width Allocation feature was turned on by default in Ruby 3.2. Since then, we haven't received bug reports or backports to the non-Variable Width Allocation code paths, so we assume that nobody is using it. We also don't plan on maintaining the non-Variable Width Allocation code, so we are going to remove it.
* `nt->serial` for `RUBY_DEBUG_LOG`Koichi Sasada2023-03-311-7/+33
| | | | | | Show native thread's serial on `RUBY_DEBUG_LOG`. `nt->serial` is also stored into `ruby_nt_serial` if the compiler supports `RB_THREAD_LOCAL_SPECIFIER`.

* func: and file: prefix for `RUBY_DEBUG_LOG_FILTER`Koichi Sasada2022-06-091-45/+121
| | | | | | | | | | | | | | | | | | | | `RUBY_DEBUG_LOG_FILTER` specified only function names but this patch also check file names for each log events. If you specify `file:` or `func:` prefix, it's only filter file names or func names (otherwize check both). foo # show log when file or func names are mached with foo func:foo # show log when func name matches foo file:foo # show log when file name matches foo -file:foo,func:bar # show log when file name does not contains foo # and func name matches bar
* add `rb_th_serial()`Koichi Sasada2022-05-241-1/+1

* extend `RUBY_DEBUG_LOG_FILTER` to reject wordsKoichi Sasada2022-05-211-11/+46
| | | | | support reject words with `-word` like RUBY_DEBUG_LOG_FILTER=-foo,-bar,baz,boo`.
* `rb_thread_t::serial` for debugKoichi Sasada2022-05-201-24/+24
| | | | | | | | | | | `rb_thread_t::serial` is auto-incremented serial number for threads and it can overflow, it means the serial is not a ID for each thread, it is only for debug print. `RUBY_DEBUG_LOG` shows this information. Also skip EC related information if EC is NULL. This patch enable to use `RUBY_DEBUG_LOG` without setup EC.
* `USE_RUBY_DEBUG_LOG` doesn't check `RUBY_DEVEL`Koichi Sasada2021-12-291-7/+3
| | | | | | | | `USE_RUBY_DEBUG_LOG` was only defined when `RUBY_DEVEL` is defined. This patch removes this dependency (`USE_RUBY_DEBUG_LOG` is defined independently from `RUBY_DEVEL`). Do not commit a patch which enables `USE_RUBY_DEBUG_LOG`.

* show ractor info on non-single ractor modeKoichi Sasada2020-12-071-1/+1
| | | | | | | 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.
* fix public interfaceKoichi Sasada2020-11-181-1/+1

* Introduce Ractor mechanism for parallel executionKoichi Sasada2020-09-031-2/+1
| | | | | | | | | | | | | | | | 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.
* ruby_debug_log: suppress warning卜部昌平2020-08-131-1/+1
| | | | | | | | | | | 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.

* support multiple filters by RUBY_DEBUG_LOG_FILTERKoichi Sasada2020-08-021-16/+45
| | | | | | 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 (#3279)Koichi Sasada2020-07-031-0/+231
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.

* VALUE size packed callinfo (ci).Koichi Sasada2020-02-221-0/+1
| | | | | | | | | | | | | | | | | | | | 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.
* move internal/debug.h definitions to internal.hKoichi Sasada2020-01-031-1/+0
| | | | Debug utilities should be accessible from any internal code.
* decouple internal.h headers卜部昌平2019-12-261-5/+12
| | | | | | | | | | | | | | | | | | 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).
