2024-01-12Fix ruby_free_proctitlePeter Zhu
It is undefined behaviour to free environ as it is managed by the system. This caused RUBY_FREE_AT_EXIT to double free on systems like Linux. This commit changes it to only free orig_environ, which is enough to make both Valgrind and macOS leaks tools to not detect memory leaks.
2024-01-11Free environ when RUBY_FREE_AT_EXITPeter Zhu
The environ is malloc'd, so it gets reported as a memory leak. This commit adds ruby_free_proctitle which frees it during shutdown when RUBY_FREE_AT_EXIT is set.

2021-02-10Fixed race in dtoa [Bug #17612]Nobuyoshi Nakada
Fixed the race condition when replacing `freelist` entry with its chained next element. At acquiring an entry, hold the entry once with the special value, then release by replacing it with the next element again after acquired. If another thread is holding the same entry at that time, spinning until the entry gets released. Co-Authored-By: Koichi Sasada <ko1@atdot.net> Notes: Merged: https://github.com/ruby/ruby/pull/4167

2020-04-13add #include guard hack卜部昌平
According to MSVC manual (*1), cl.exe can skip including a header file when that: - contains #pragma once, or - starts with #ifndef, or - starts with #if ! defined. GCC has a similar trick (*2), but it acts more stricter (e. g. there must be _no tokens_ outside of #ifndef...#endif). Sun C lacked #pragma once for a looong time. Oracle Developer Studio 12.5 finally implemented it, but we cannot assume such recent version. This changeset modifies header files so that each of them include strictly one #ifndef...#endif. I believe this is the most portable way to trigger compiler optimizations.

2019-10-12missing/setproctitle.c: remove nonsense NULL checkYusuke Endoh
If fmt is NULL, ptitle is uninitialized and used. SETPROCTITLE(3bsd) says "If fmt is NULL, the process title is restored", but looks like the feature is not implemented in missing/setproctitle.c. At least the source code of ruby does not pass NULL to the function. So I assume this function requires non-NULL fmt. This issue was found by Coverity Scan.

2019-01-06internal.h: unify our own stdtbool.h implementationk0kubun
because we had another one in missing/stdbool.h as well. Assuming that _Bool does not exist when stdbool.h is absent, I'm in favor of r57462 implementation rather than r61326. Note that Visual Studio 2013 has stdbool.h and thus r57462's commit message is somewhat misleading. This missing/stdbool.h is for Visual Studio 2012 or older, and for Oracle Solaris Studio 12.2 or older because it's added in 12.3 https://docs.oracle.com/cd/E24457_01/html/E21987/gkeza.html. missing/stdbool.h: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66739 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-11-12string.c: fix memory leak in String#cryptrhe
Use ALLOCV to allocate struct crypt_data for slightly cleaner and less error-prone code. It is currently possible it leaks when an invalid argument is passed to String#crypt or rb_str_new_cstr() fails to allocate memory. SIZEOF_CRYPT_DATA macro in missing/crypt.h is removed since it is not used any longer. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60748 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
