* `Regexp` in `MatchData` can be `nil`Nobuyoshi Nakada2020-01-161-0/+1
| | | | | | | `String#sub` with a string pattern defers creating a `Regexp` until `MatchData#regexp` creates a `Regexp` from the matched string. `Regexp#last_match(group_name)` accessed its content without creating the `Regexp` though. [Bug #16508]

| | | | | | This removes the related tests, and puts the related specs behind version guards. This affects all code in lib, including some libraries that may want to support older versions of Ruby.

| | | | | | We can check the function pointer passed to rb_define_singleton_method like how we do so in rb_define_method. Doing so revealed many arity mismatches.

* rb_define_hooked_variable now free from ANYARGS卜部昌平2019-08-271-10/+16
| | | | | | | | | After 5e86b005c0f2ef30df2f9906c7e2f3abefe286a2, I now think ANYARGS is dangerous and should be extinct. This commit uses rb_gvar_getter_t / rb_gvar_setter_t for rb_define_hooked_variable / rb_define_virtual_variable which revealed lots of function prototype inconsistencies. Some of them were literally decades old, going back to dda5dc00cff334cac373096d444a0fd59e716124.
* Reuse match dataNobuyoshi Nakada2019-07-281-0/+6
| | | | * string.c (rb_str_split_m): reuse occupied match data. [Bug #16024]
* Document encoding of string returned by Regexp.quote [ci skip]Jeremy Evans2019-07-221-2/+2
| | | | | | | | | Also, remove documentation about returning self, which makes no sense as self would be the Regexp class. It could be interpreted as return the argument if no changes were made, but that hasn't been the behavior at least since 1.8.7 (and probably before). Fixes [Bug #10239]

* char is not unsignedshyouhei2018-11-211-4/+5
| | | | | | | | | | It seems that decades ago, ruby was written under assumption that char is unsigned. Which is of course a false assumption. We need to explicitly store a numeric value into an unsigned char variable to tell we expect 0..255 value. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65900 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* char is neither signed nor unsignedshyouhei2018-11-121-5/+6
| | | | | | | | | | read_escaped_byte() returns values of range -1...256. -1 indicates error. So the function basically expects char to be 0..255 range. There is no such guarantee. `char` is not always unsigned. We need to explicitly declare chbuf to be unsigned char. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65677 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* mjit_compile.c: merge initial JIT compilerk0kubun2018-02-041-1/+1

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.
