Allow Dir.home to work for non-login procs when $HOME not set 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.

improve handling of timer thread shutdown Shutting down the timer thread now always closes pipes to free FDs. In fact, we close the write ends of the pipes is done in the main RubyVM to signal the timer thread shutdown. To effectively close pipes, we implement userspace locks via atomics to force the pipe closing thread to wait on any signal handlers which may be waking up. While we're at it, improve robustness during resource exhaustion and allow it to limp along non-fatally if restarting a timer thread fails.

This reverts r51268 Note: this change is tested with VM_CHECK_MODE 1 in vm_core.h * process.c (close_unless_reserved): add extra check (dup2_with_divert): remove (redirect_dup2): use dup2 without divert (before_exec_non_async_signal_safe): adjust call + comment (rb_f_exec): stop timer thread for all OSes (rb_exec_without_timer_thread): remove * eval.c (ruby_cleanup): adjust call * thread.c (rb_thread_stop_timer_thread): always close pipes * thread_pthread.c (struct timer_thread_pipe): add writing field, mark owner_process volatile for signal handlers (rb_thread_wakeup_timer_thread_fd): check valid FD (rb_thread_wakeup_timer_thread): set writing flag to prevent close (rb_thread_wakeup_timer_thread_low): ditto (CLOSE_INVALIDATE): new macro (close_invalidate): new function (close_communication_pipe): removed (setup_communication_pipe_internal): make errors non-fatal (setup_communication_pipe): ditto (thread_timer): close reading ends inside timer thread (rb_thread_create_timer_thread): make errors non-fatal (native_stop_timer_thread): close write ends only, always, wait for signal handlers to finish (rb_divert_reserved_fd): remove * thread_win32.c (native_stop_timer_thread): adjust (untested) (rb_divert_reserved_fd): remove * vm_core.h: adjust prototype git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@51576 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

waitpid_sleep(VALUE x)
hijack SIGCHLD handler for internal use Use a global SIGCHLD handler to guard all callers of rb_waitpid. To work safely with multi-threaded programs, we introduce a VM-wide waitpid_lock to be acquired BEFORE fork/vfork spawns the process. This is to be combined with the new ruby_waitpid_locked function used by mjit.c in a non-Ruby thread. Ruby-level SIGCHLD handlers registered with Signal.trap(:CHLD) continues to work as before and there should be no regressions in any existing use cases. Splitting the wait queues for PID > 0 and groups (PID <= 0) ensures we favor PID > 0 callers. The disabling of SIGCHLD in rb_f_system is longer necessary, as we use deferred signal handling and no longer make ANY blocking waitpid syscalls in other threads which could "beat" the waitpid call made by rb_f_system. We prevent SIGCHLD from firing in normal Ruby Threads and only enable it in the timer-thread, to prevent spurious wakeups from in test/-ext-/gvl/test_last_thread.rb with MJIT enabled. I've tried to guard as much of the code for RUBY_SIGCHLD==0 using C "if" statements rather than CPP "#if" so to reduce the likelyhood of portability problems as the compiler will see more code. We also work to suppress false-positives from Process.wait(-1, Process::WNOHANG) to quiets warnings from spec/ruby/core/process/wait2_spec.rb with MJIT enabled. Lastly, we must implement rb_grantpt for ext/pty. We need a MJIT-compatible way of supporting grantpt(3) which may spawn the `pt_chown' binary and call waitpid(2) on it.

has historically been documented as if it didn't take any arguments
despite the fact that it's just an alias for ::waitpid(). The way I
have it below is more truthful, but a little confusing.
I also took the liberty of putting in the pid values, as they're
pretty useful, and it looked as if the original 'ri' output was
supposed to contain them after "[...]depending on the value of
aPid:".
The 'ansi' and 'bs' formats of the ri output don't display the
definition list for some reason, but the plain text one does.

* The waiting thread returns the exit status of the detached process
* when it terminates, so you can use Thread#join to
* know the result. If specified _pid_ is not a valid child process
* ID, the thread returns +nil+ immediately.
*
* The waiting thread has #pid method which returns the pid.
*
* In this first example, we don't reap the first child process, so
* it appears as a zombie in the process status display.
*
* p1 = fork { sleep 0.1 }
* p2 = fork { sleep 0.2 }
* Process.waitpid(p2)
* sleep 2
* system("ps -ho pid,state -p #{p1}")
*
* <em>produces:</em>
*
* 27389 Z
*
* In the next example, Process::detach is used to reap
* the child automatically.
*
* p1 = fork { sleep 0.1 }
* p2 = fork { sleep 0.2 }
* Process.detach(p1)
* Process.waitpid(p2)
* sleep 2
* system("ps -ho pid,state -p #{p1}")

/*
* call-seq:
* exec([env,] command... [,options])
*
* Replaces the current process by running the given external _command_, which
* can take one of the following forms:
*
* [<code>exec(commandline)</code>]
* command line string which is passed to the standard shell
* [<code>exec(cmdname, arg1, ...)</code>]
* command name and one or more arguments (no shell)
* [<code>exec([cmdname, argv0], arg1, ...)</code>]
* command name, argv[0] and zero or more arguments (no shell)
*
* In the first form, the string is taken as a command line that is subject to
* shell expansion before being executed.
*
* The standard shell always means <code>"/bin/sh"</code> on Unix-like systems,
* otherwise, <code>ENV["RUBYSHELL"]</code> or <code>ENV["COMSPEC"]</code> on
* Windows and similar. The command is passed as an argument to the
* <code>"-c"</code> switch to the shell, except in the case of +COMSPEC+.
*
* If the string from the first form (<code>exec("command")</code>) follows
* these simple rules:
*
* * no meta characters
* * not starting with shell reserved word or special built-in
* * Ruby invokes the command directly without shell
*
* You can force shell invocation by adding ";" to the string (because ";" is
* a meta character).
*
* Note that this behavior is observable by pid obtained
* (return value of spawn() and IO#pid for IO.popen) is the pid of the invoked
* command, not shell.
*
* In the second form (<code>exec("command1", "arg1", ...)</code>), the first
* is taken as a command name and the rest are passed as parameters to command
* with no shell expansion.
*
* In the third form (<code>exec(["command", "argv0"], "arg1", ...)</code>),
* starting a two-element array at the beginning of the command, the first
* element is the command to be executed, and the second argument is used as
* the <code>argv[0]</code> value, which may show up in process listings.
*
* In order to execute the command, one of the <code>exec(2)</code> system
* calls are used, so the running command may inherit some of the environment
* of the original program (including open file descriptors).

* pid = spawn("tar xf ruby-2.0.0-p195.tar.bz2")
* Process.wait pid
*
* pid = spawn(RbConfig.ruby, "-eputs'Hello, world!'")
* Process.wait pid
*
* This method is similar to Kernel#system but it doesn't wait for the command
* to finish.
*
* The parent process should
* use Process.wait to collect
* the termination status of its child or
* use Process.detach to register
* disinterest in their status;
* otherwise, the operating system may accumulate zombie processes.
*
* spawn has bunch of options to specify process attributes:
*
* env: hash
* name => val : set the environment variable
* name => nil : unset the environment variable
*
* the keys and the values except for +nil+ must be strings.
* command...:
* commandline : command line string which is passed to the standard shell
* cmdname, arg1, ... : command name and one or more arguments (This form does not use the shell. See below for caveats.)
* [cmdname, argv0], arg1, ... : command name, argv[0] and zero or more arguments (no shell)
* options: hash
* clearing environment variables:
* :unsetenv_others => true : clear environment variables except specified by env
* :unsetenv_others => false : don't clear (default)
* process group:
* :pgroup => true or 0 : make a new process group
* :pgroup => pgid : join the specified process group
* :pgroup => nil : don't change the process group (default)
* create new process group: Windows only
* :new_pgroup => true : the new process is the root process of a new process group
* :new_pgroup => false : don't create a new process group (default)
* resource limit: resourcename is core, cpu, data, etc. See Process.setrlimit.
* :rlimit_resourcename => limit
* :rlimit_resourcename => [cur_limit, max_limit]
* umask:
* :umask => int
* redirection:
* key:
* FD : single file descriptor in child process
* [FD, FD, ...] : multiple file descriptor in child process
* value:
* FD : redirect to the file descriptor in parent process
* string : redirect to file with open(string, "r" or "w")
* [string] : redirect to file with open(string, File::RDONLY)
* [string, open_mode] : redirect to file with open(string, open_mode, 0644)
* [string, open_mode, perm] : redirect to file with open(string, open_mode, perm)
* [:child, FD] : redirect to the redirected file descriptor
* :close : close the file descriptor in child process
* FD is one of follows
* :in : the file descriptor 0 which is the standard input
* :out : the file descriptor 1 which is the standard output
* :err : the file descriptor 2 which is the standard error
* integer : the file descriptor of specified the integer
* io : the file descriptor specified as io.fileno
* file descriptor inheritance: close non-redirected non-standard fds (3, 4, 5, ...) or not
* :close_others => false : inherit
* current directory:
* :chdir => str

*
* Another way to merge multiple file descriptors is [:child, fd].
* \[:child, fd] means the file descriptor in the child process.
* This is different from fd.
* For example, :err=>:out means redirecting child stderr to parent stdout.
* But :err=>[:child, :out] means redirecting child stderr to child stdout.
* They differ if stdout is redirected in the child process as follows.
*
* # stdout and stderr is redirected to log file.
* # The file "log" is opened just once.
* pid = spawn(command, :out=>["log", "w"], :err=>[:child, :out])
*
* \[:child, :out] can be used to merge stderr into stdout in IO.popen.
* In this case, IO.popen redirects stdout to a pipe in the child process
* and [:child, :out] refers the redirected stdout.
*
* io = IO.popen(["sh", "-c", "echo out; echo err >&2", :err=>[:child, :out]])
* p io.read #=> "out\nerr\n"
*
* The <code>:chdir</code> key in +options+ specifies the current directory.
*
* pid = spawn(command, :chdir=>"/var/tmp")
*
* spawn closes all non-standard unspecified descriptors by default.
* The "standard" descriptors are 0, 1 and 2.
* This behavior is specified by :close_others option.
* :close_others doesn't affect the standard descriptors which are
* closed only if :close is specified explicitly.

Allow Dir.home to work for non-login procs when $HOME not set 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.

*
* Note that SUS stands for Single Unix Specification.
* SUS contains POSIX and clock_gettime is defined in the POSIX part.
* SUS defines CLOCK_REALTIME mandatory but
* CLOCK_MONOTONIC, CLOCK_PROCESS_CPUTIME_ID and CLOCK_THREAD_CPUTIME_ID are optional.
*
* Also, several symbols are accepted as +clock_id+.
* There are emulations for clock_gettime().
*
* For example, Process::CLOCK_REALTIME is defined as
* +:GETTIMEOFDAY_BASED_CLOCK_REALTIME+ when clock_gettime() is not available.
*
* Emulations for +CLOCK_REALTIME+:
* [:GETTIMEOFDAY_BASED_CLOCK_REALTIME]
* Use gettimeofday() defined by SUS.
* (SUSv4 obsoleted it, though.)
* The resolution is 1 microsecond.
* [:TIME_BASED_CLOCK_REALTIME]
* Use time() defined by ISO C.
* The resolution is 1 second.
*
* Emulations for +CLOCK_MONOTONIC+:
* [:MACH_ABSOLUTE_TIME_BASED_CLOCK_MONOTONIC]
* Use mach_absolute_time(), available on Darwin.
* The resolution is CPU dependent.
* [:TIMES_BASED_CLOCK_MONOTONIC]
* Use the result value of times() defined by POSIX.
* POSIX defines it as "times() shall return the elapsed real time, in clock ticks, since an arbitrary point in the past (for example, system start-up time)".
* For example, GNU/Linux returns a value based on jiffies and it is monotonic.
* However, 4.4BSD uses gettimeofday() and it is not monotonic.
* (FreeBSD uses clock_gettime(CLOCK_MONOTONIC) instead, though.)
* The resolution is the clock tick.
* "getconf CLK_TCK" command shows the clock ticks per second.
* (The clock ticks per second is defined by HZ macro in older systems.)
* If it is 100 and clock_t is 32 bits integer type, the resolution is 10 millisecond and
* cannot represent over 497 days.
*
* Emulations for +CLOCK_PROCESS_CPUTIME_ID+:
* [:GETRUSAGE_BASED_CLOCK_PROCESS_CPUTIME_ID]
* Use getrusage() defined by SUS.
* getrusage() is used with RUSAGE_SELF to obtain the time only for
* the calling process (excluding the time for child processes).
* The result is addition of user time (ru_utime) and system time (ru_stime).
* The resolution is 1 microsecond.
* [:TIMES_BASED_CLOCK_PROCESS_CPUTIME_ID]
* Use times() defined by POSIX.
* The result is addition of user time (tms_utime) and system time (tms_stime).
* tms_cutime and tms_cstime are ignored to exclude the time for child processes.
* The resolution is the clock tick.
* "getconf CLK_TCK" command shows the clock ticks per second.
* (The clock ticks per second is defined by HZ macro in older systems.)
* If it is 100, the resolution is 10 millisecond.
* [:CLOCK_BASED_CLOCK_PROCESS_CPUTIME_ID]
* Use clock() defined by ISO C.
* The resolution is 1/CLOCKS_PER_SEC.
* CLOCKS_PER_SEC is the C-level macro defined by time.h.
* SUS defines CLOCKS_PER_SEC is 1000000.
* Non-Unix systems may define it a different value, though.
* If CLOCKS_PER_SEC is 1000000 as SUS, the resolution is 1 microsecond.
* If CLOCKS_PER_SEC is 1000000 and clock_t is 32 bits integer type, it cannot represent over 72 minutes.
*
* If the given +clock_id+ is not supported, Errno::EINVAL is raised.
*
* +unit+ specifies a type of the return value.
*
* [:float_second] number of seconds as a float (default)
* [:float_millisecond] number of milliseconds as a float
* [:float_microsecond] number of microseconds as a float
* [:second] number of seconds as an integer
* [:millisecond] number of milliseconds as an integer
* [:microsecond] number of microseconds as an integer
* [:nanosecond] number of nanoseconds as an integer
*
* The underlying function, clock_gettime(), returns a number of nanoseconds.
* Float object (IEEE 754 double) is not enough to represent
* the return value for CLOCK_REALTIME.
* If the exact nanoseconds value is required, use +:nanoseconds+ as the +unit+.
*
* The origin (zero) of the returned value varies.
* For example, system start up time, process start up time, the Epoch, etc.
*
* The origin in CLOCK_REALTIME is defined as the Epoch
* (1970-01-01 00:00:00 UTC).
* But some systems count leap seconds and others doesn't.
* So the result can be interpreted differently across systems.
* Time.now is recommended over CLOCK_REALTIME.

Increasing the footprint of our C-API larger is also detrimental to our development as it encourages tighter coupling with our internals; making it harder for us to preserve compatibility.
