2020-02-27st.c: remove variables that are no longer usedYusuke Endoh
to suppress a warning "variable 'check' set but not used"
2020-02-26kill ST_DEBUG [Bug #16521]卜部昌平
This compile-time option has been broken for years (at least since commit 4663c224fa6c925ce54af32fd1c1cbac9508f5ec, according to git bisect). Let's delete codes that no longer work. Notes: Merged: https://github.com/ruby/ruby/pull/2926

2019-12-26decouple internal.h headers卜部昌平
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). Notes: Merged: https://github.com/ruby/ruby/pull/2711

2019-09-22st.c: Use rb_st_* prefix instead of st_* (#2479)Yusuke Endoh
The original st.c was public domain hash table implementation, but Ruby's st.c is highly modified, and its data structure is not compatiblie with the original one. Therefore, when creating an extension library to wrap C code that uses the original st.c, the symbols conflict, which leads to segfault. This changes the prefix `st_*` of st.c functions to `rb_st_*` for reflecting that they are specific to Ruby's, and avoid symbol conflicts. Notes: Merged-By: mame <mame@ruby-lang.org>

2019-08-27struct st_hash_type now free from ANYARGS卜部昌平
After 5e86b005c0f2ef30df2f9906c7e2f3abefe286a2, I now think ANYARGS is dangerous and should be extinct. This commit adds function prototypes for struct st_hash_type. Honestly I don't understand why they were commented out at the first place.

After 5e86b005c0f2ef30df2f9906c7e2f3abefe286a2, I now think ANYARGS is dangerous and should be extinct. This commit deletes ANYARGS from st_foreach. I strongly believe that this commit should have had come with b0af0592fdd9e9d4e4b863fde006d67ccefeac21, which added extra parameter to st_foreach callbacks.

2019-01-15st.c (rb_hash_bulk_insert_into_st_table): avoid out-of-bounds writemame
"hash_bulk_insert" first expands the table, but the target size was wrong: it was calculated by "num_entries + (size to buld insert)", but it was wrong when "num_entries < entries_bound", i.e., it has a deleted entry. "hash_bulk_insert" adds the given entries from entries_bound, which led to out-of-bounds write access. [Bug #15536] As a simple fix, this commit changes the calculation to "entries_bound + size". I'm afraid if this might be inefficient, but I think it is safe anyway. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66832 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* hash.c, internal.h: support theap for small Hash. Introduce RHASH_ARRAY (li_table) besides st_table and small Hash (<=8 entries) are managed by an array data structure. This array data can be managed by theap. If st_table is needed, then converting array data to st_table data. For st_table using code, we prepare "stlike" APIs which accepts hash value and are very similar to st_ APIs.

2018-02-13st.c: retry operations if rebuiltnormal
Calling the .eql? and .hash methods during a Hash operation can result in a thread switch or a signal handler to run: allowing one execution context to rebuild the hash table while another is still reading or writing the table. This results in a use-after-free bug affecting the thread_safe-0.3.6 test suite and likely other bugs. This bug did not affect users of commonly keys (String, Symbol, Fixnum) as those are optimized to avoid method dispatch for .eql? and .hash methods. A separate version of this change needs to be ported to Ruby 2.3.x which had a different implementation of st.c but was affected by the same bug. * st.c: Add comment about table rebuilding during comparison. (DO_PTR_EQUAL_CHECK): New macro. (REBUILT_TABLE_ENTRY_IND, REBUILT_TABLE_BIN_IND): New macros. (find_entry, find_table_entry_ind, find_table_bin_ind): Use new macros. Return the rebuild flag. (find_table_bin_ptr_and_reserve): Ditto. (st_lookup, st_get_key, st_insert, st_insert2): Retry the operation if the table was rebuilt. (st_general_delete, st_shift, st_update, st_general_foreach): Ditto. (st_rehash_linear, st_rehash_indexed): Use DO_PTR_EQUAL_CHECK. Return the rebuild flag. (st_rehash): Retry the operation if the table was rebuilt. [ruby-core:85510] [Ruby trunk Bug#14357] Thanks to Vit Ondruch for reporting the bug.

2018-02-04mjit_compile.c: merge initial JIT compilerk0kubun
which has been developed by Takashi Kokubun <takashikkbn@gmail> as YARV-MJIT. Many of its bugs are fixed by wanabe <s.wanabe@gmail.com>. This JIT compiler is designed to be a safe migration path to introduce JIT compiler to MRI. So this commit does not include any bytecode changes or dynamic instruction modifications, which are done in original MJIT. This commit even strips off some aggressive optimizations from YARV-MJIT, and thus it's slower than YARV-MJIT too. But it's still fairly faster than Ruby 2.5 in some benchmarks (attached below). Note that this JIT compiler passes `make test`, `make test-all`, `make test-spec` without JIT, and even with JIT. Not only it's perfectly safe with JIT disabled because it does not replace VM instructions unlike MJIT, but also with JIT enabled it stably runs Ruby applications including Rails applications. I'm expecting this version as just "initial" JIT compiler. I have many optimization ideas which are skipped for initial merging, and you may easily replace this JIT compiler with a faster one by just replacing mjit_compile.c. `mjit_compile` interface is designed for the purpose. common.mk: update dependencies for mjit_compile.c. internal.h: declare `rb_vm_insn_addr2insn` for MJIT. vm.c: exclude some definitions if `-DMJIT_HEADER` is provided to compiler. This avoids to include some functions which take a long time to compile, e.g. vm_exec_core. Some of the purpose is achieved in transform_mjit_header.rb (see `IGNORED_FUNCTIONS`) but others are manually resolved for now. Load mjit_helper.h for MJIT header. mjit_helper.h: New. This is a file used only by JIT-ed code. I'll refactor `mjit_call_cfunc` later. vm_eval.c: add some #ifdef switches to skip compiling some functions like Init_vm_eval. win32/mkexports.rb: export thread/ec functions, which are used by MJIT. include/ruby/defines.h: add MJIT_FUNC_EXPORTED macro alis to clarify that a function is exported only for MJIT. array.c: export a function used by MJIT. bignum.c: ditto. class.c: ditto. compile.c: ditto. error.c: ditto. gc.c: ditto. hash.c: ditto. iseq.c: ditto. numeric.c: ditto. object.c: ditto. proc.c: ditto. re.c: ditto. st.c: ditto. string.c: ditto. thread.c: ditto. variable.c: ditto. vm_backtrace.c: ditto. vm_insnhelper.c: ditto. vm_method.c: ditto. I would like to improve maintainability of function exports, but I believe this way is acceptable as initial merging if we clarify the new exports are for MJIT (so that we can use them as TODO list to fix) and add unit tests to detect unresolved symbols. I'll add unit tests of JIT compilations in succeeding commits.

This gives the newhash VM instruction the same string reuse capabilities as rb_hash_aset. * st.c (str_key): new wrapper function to call rb_fstring_existing (rb_hash_bulk_insert): use str_key * test/ruby/test_optimization.rb (test_hash_reuse_fstring): ensure key reuse for newhash instructions git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59355 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-04-27refactor newhash (revision 58463 another try) [fix GH-1600]shyouhei
* st.c (rb_hash_bulk_insert): new API to bulk insert entries into a hash. Given arguments are first inserted into the table at once, then reindexed. This is faster than inserting things using rb_hash_aset() one by one. This arrangement (rb_ prefixed function placed in st.c) is unavoidable because it both touches table internal and write barrier at once. * internal.h: delcare the new function. * hash.c (rb_hash_s_create): use the new function. * vm.c (core_hash_merge): ditto. * insns.def (newhash): ditto. * test/ruby/test_hash.rb: more coverage on hash creation. * test/ruby/test_literal.rb: ditto. ----------------------------------------------------------- benchmark results: minimum results in each 7 measurements.
