* * process.c (rb_execarg_parent_start1): new macro ALWAYS_NEED_ENVPngoto2015-06-191-4/+13
| | | | | | | | | | | | | | | | | | | | | | | | to generate envp_str anytime on Solaris 10 (or earlier version of Solaris) to avoid calling execv() which is async-signal unsafe on Solaris 10. [Bug #11265] [ruby-dev:49089] * process.c (exec_with_sh, proc_exec_cmd): On Solaris 10, because ALWAYS_NEED_ENVP is 1 and envp_str is always generated, execv() in exec_with_sh() and proc_exec_cmd() are never called. To guarantee this, execv() is replaced by a macro to print out error message on Solaris 10. * process.c (proc_exec_sh): Because proc_exec_sh() may be called by rb_proc_exec() with envp_str = Qfalse, execl() is replaced by a macro that calls execle() with "extern char **environ" traditional global variable on Solaris 10. TODO: This may be unsafe and sholud be changed in the future. Although rb_proc_exec() is not used from inside current version of ruby, it may be called by third-party extensions. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@50977 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
