* Posix systems record information on processes using a 16-bit
|
|
|
|
* integer. The lower bits record the process status (stopped,
|
|
|
|
* exited, signaled) and the upper bits possibly contain additional
|
|
|
|
* information (for example the program's return code in the case of
|
|
|
|
* exited processes). Pre Ruby 1.8, these bits were exposed directly
|
|
|
|
* to the Ruby program. Ruby now encapsulates these in a
|
|
|
|
* <code>Process::Status</code> object. To maximize compatibility,
|
|
|
|
* however, these objects retain a bit-oriented interface. In the
|
|
|
|
* descriptions that follow, when we talk about the integer value of
|
|
|
|
* _stat_, we're referring to this 16 bit value.

/* [MG]:FIXME: I wasn't sure how this should be done, since ::wait()
|
|
|
|
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.

* Some operating systems retain the status of terminated child

* processes until the parent collects that status (normally using
|
|
|
|
* some variant of <code>wait()</code>. If the parent never collects
|
|
|
|
* this status, the child stays around as a <em>zombie</em> process.
|
|
|
|
* <code>Process::detach</code> prevents this by setting up a
|
|
|
|
* separate Ruby thread whose sole job is to reap the status of the
|
|
|
|
* process _pid_ when it terminates. Use <code>detach</code>
|
|
|
|
* only when you do not intent to explicitly wait for the child to
|
|
|
|
* terminate. <code>detach</code> only checks the status
|
|
|
|
* periodically (currently once each second).
|
2004-02-09 02:30:17 -05:00
|
|
|
*
|
|
|
|
* The waiting thread returns the exit status of the detached process
|
|
|
|
* when it terminates, so you can use <code>Thread#join</code> to
|
|
|
|
* know the result. If specified _pid_ is not a valid child process
|
|
|
|
* ID, the thread returns +nil+ immediately.
|
|
|
|
*
|
2004-01-02 01:01:12 -05:00
|
|
|
* In this first example, we don't reap the first child process, so
|
|
|
|
* it appears as a zombie in the process status display.
