2020-09-03Introduce Ractor mechanism for parallel executionKoichi Sasada
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. Notes: Merged: https://github.com/ruby/ruby/pull/3365

2020-06-29add UNREACHABLE_RETURN卜部昌平
Not every compilers understand that rb_raise does not return. When a function does not end with a return statement, such compilers can issue warnings. We would better tell them about reachabilities. Notes: Merged: https://github.com/ruby/ruby/pull/3247

2020-05-23Allow Dir.home to work for non-login procs when $HOME not setAlan D. Salewski
Allow the 'Dir.home' method to reliably locate the user's home directory when all three of the following are true at the same time: 1. Ruby is running on a Unix-like OS 2. The $HOME environment variable is not set 3. The process is not a descendant of login(1) (or a work-alike) The prior behavior was that the lookup could only work for login-descended processes. This is accomplished by looking up the user's record in the password database by uid (getpwuid_r(3)) as a fallback to the lookup by name (getpwname_r(3)) which is still attempted first (based on the name, if any, returned by getlogin_r(3)). If getlogin_r(3), getpwnam_r(3), and/or getpwuid_r(3) is not available at compile time, will fallback on using their respective non-*_r() variants: getlogin(3), getpwnam(3), and/or getpwuid(3). The rationale for attempting to do the lookup by name prior to doing it by uid is to accommodate the possibility of multiple login names (each with its own record in the password database, so each with a potentially different home directory) being mapped to the same uid (as is explicitly allowed for by POSIX; see getlogin(3posix)). Preserves the existing behavior for login-descended processes, and adds the new capability of having Dir.home being able to find the user's home directory for non-login-descended processes.

2020-05-10Run rb_syswait on exec failureTakashi Kokubun
not only when !w but also when w == WAITPID_LOCK_ONLY. See also: f7c0cc36920a4ed14a3ab1ca6cfdf18ceff1e5d5 and a2264342063260d660b99872eaf5080f6ab08e81. We thought this change was an oversight in the latter commit. Without this change, the test fails like: $ make test-all TESTS="../test/ruby/test_process.rb -n test_exec_failure_leaves_no_child" RUN_OPTS="--jit" ... 1) Failure: TestProcess#test_exec_failure_leaves_no_child [/home/k0kubun/src/github.com/ruby/ruby/test/ruby/test_process.rb:2493]: Expected [[26799, #<Process::Status: pid 26799 exit 127>]] to be empty.

2020-05-02internal/process.h: add a no-warning simple wrapper for fork(2)Yusuke Endoh
As fork(2) is deprecated, its calls must be guarded by `COMPILER_WARNING_IGNORED(-Wdeprecated-declarations)`. All usages of fork(2) in process have been alread guarded. A new call to fork(2) was added in ruby.c with f22c4ff359498ab342e4b6d6feb21af6004ee270. This caused a build failure on Solaris 11. It may hide a bug to guard big code unnecessarily, so this change introduces a simple wrapper "rb_fork" whose definition is guarded, and replaces all calls to fork(2) with the wrapper function.

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

2019-11-18Warn on access/modify of $SAFE, and remove effects of modifying $SAFEJeremy Evans
This removes the security features added by $SAFE = 1, and warns for access or modification of $SAFE from Ruby-level, as well as warning when calling all public C functions related to $SAFE. This modifies some internal functions that took a safe level argument to no longer take the argument. rb_require_safe now warns, rb_require_string has been added as a version that takes a VALUE and does not warn. One public C function that still takes a safe level argument and that this doesn't warn for is rb_eval_cmd. We may want to consider adding an alternative method that does not take a safe level argument, and warn for rb_eval_cmd. Notes: Merged: https://github.com/ruby/ruby/pull/2476

2019-10-05Fix potential memory leaks by `rb_imemo_tmpbuf_auto_free_pointer`Nobuyoshi Nakada
This function has been used wrongly always at first, "allocate a buffer then wrap it with tmpbuf". This order can cause a memory leak, as tmpbuf creation also can raise a NoMemoryError exception. The right order is "create a tmpbuf then allocate&wrap a buffer". So the argument of this function is rather harmful than just useless. TODO: * Rename this function to more proper name, as it is not used "temporary" (function local) purpose. * Allocate and wrap at once safely, like `ALLOCV`.

2019-08-27rb_define_hooked_variable now free from ANYARGS卜部昌平
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.
2019-08-26uid_t and gid_t are narrower than VALUE.卜部昌平
Often uid / gid are 16 bit or 32 bit integers, while VALUE are 32 to 64 bits. They tend to differ in size. Because rb_ensure expects its callbacks to take VALUE arguments, narrowing must be done by hand, otherwise data corruption can happen depending on machine ABI.
