Update of /cvs-repository/Zope/lib/python/zdaemon
In directory cvs.zope.org:/tmp/cvs-serv22928/lib/python/zdaemon

Modified Files:
      Tag: Zope-2_7-branch
	schema.xml zdctl.py zdrun.py 
Log Message:
Change the ZEO control process and configuration schema so that a single
configuration file can be used for both the runzeo and zeoctl scripts.
This makes it easier to keep all the configuration needed to support the
ZEO server process in a single file.
For more explanation of the changes, see

-      This section describes the options for zdctl.py and zdrun.py.
-      The only required option is "program".  Many other options have
-      no default value specified in the schema; in some cases, the
-      program calculates a dynamic default, in others, the feature
-      associated with the option is disabled.
-
-      For those options that also have corresponding command-line
-      options, the command line option (short and long form) are given
-      here too.

-    <key name="program" datatype="string-list"
-	 required="yes">
-      <description>
-        Command-line option: -p or --program (zdctl.py only).
-
-        This option gives the command used to start the subprocess
-        managed by zdrun.py.  This is currently a simple list of
-        whitespace-delimited words. The first word is the program
-        file, subsequent words are its command line arguments.  If the
-        program file contains no slashes, it is searched using $PATH.
-        (XXX There is no way to to include whitespace in the program
-        file or an argument, and under certain circumstances other
-        shell metacharacters are also a problem, e.g. the "foreground"
-        command of zdctl.py.)
-
-        NOTE: zdrun.py doesn't use this option; it uses its positional
-        arguments.  Rather, zdctl.py uses this option to determine the
-        positional argument with which to invoke zdrun.py.  (XXX This
-        could be better.)

-      <description>
-        Path to the Python interpreter.  Used by zdctl.py to start the

-      <description>
-        Path to the zdrun.py script.  Used by zdctl.py to start the

-      <description>
-        Command-line option: -s or --socket-name.
-
-        The pathname of the Unix domain socket used for communication
-        between zdctl.py and zdrun.py.  The default is relative to the
-        current directory in which zdctl.py and zdrun.py are started.
-        You want to specify an absolute pathname here.

-      <description>
-        Command-line option: -d or --daemon.
-
-        If this option is true, zdrun.py runs in the background as a
-        true daemon.  It forks an child process which becomes the
-        subprocess manager, while the parent exits (making the shell
-        that started it believe it is done).  The child process also
-        does the following:
-
-        - if the directory option is set, change into that directory
-
-        - redirect stdin, stdout and stderr to /dev/null
-
-        - call setsid() so it becomes a session leader
-
-        - call umask(022)

-    <key name="directory" datatype="existing-directory"
-	 required="no">
-      <description>
-        Command-line option: -z or --directory.
-
-        If the daemon option is true, this option can specify a
-        directory into which zdrun.py changes as part of the
-        "daemonizing".  If the daemon option is false, this option is
-        ignored.

-
-    <key name="backoff-limit" datatype="integer"
-	 required="no"
-	 default="10">
-      <description>
-        Command-line option: -b or --backoff-limit.
-
-        When the subprocess crashes, zdrun.py inserts a one-second
-        delay before it restarts it.  When the subprocess crashes
-        again right away, the delay is incremented by one second, and
-        so on.  What happens when the delay has reached the value of
-        backoff-limit (in seconds), depends on the value of the
-        forever option.  If forever is false, zdrun.py gives up at
-        this point, and exits.  An always-crashing subprocess will
-        have been restarted exactly backoff-limit times in this case.
-        If forever is true, zdrun.py continues to attempt to restart
-        the process, keeping the delay at backoff-limit seconds.
-
-        If the subprocess stays up for more than backoff-limit
-        seconds, the delay is reset to 1 second.

-      <description>
-        Command-line option: -f or --forever.
-
-        If this option is true, zdrun.py will keep restarting a
-        crashing subprocess forever.  If it is false, it will give up
-        after backoff-limit crashes in a row.  See the description of
-        backoff-limit for details.

-
-    <key name="exit-codes" datatype="zdaemon.zdoptions.list_of_ints"
-	 required="no"
-	 default="0,2">
-      <description>
-        Command-line option: -x or --exit-codes.
-
-        If the subprocess exits with an exit status that is equal to
-        one of the integers in this list, zdrun.py will not restart
-        it.  The default list requires some explanation.  Exit status
-        0 is considered a willful successful exit; the ZEO and Zope
-        server processes use this exit status when they want to stop
-        without being restarted.  (Including in response to a
-        SIGTERM.)  Exit status 2 is typically issued for command line
-        syntax errors; in this case, restarting the program will not
-        help!
-
-        NOTE: this mechanism overrides the backoff-limit and forever
-        options; i.e. even if forever is true, a subprocess exit
-        status code in this list makes zdrun.py give up.  To disable
-        this, change the value to an empty list.

-    <key name="user" datatype="string"
-	 required="no">
-      <description>
-        Command-line option: -u or --user.
-
-        When zdrun.py is started by root, this option specifies the
-        user as who the the zdrun.py process (and hence the daemon
-        subprocess) will run.  This can be a user name or a numeric
-        user id.  Both the user and the group are set from the
-        corresponding password entry, using setuid() and setgid().
-        This is done before zdrun.py does anything else besides
-        parsing its command line arguments.
-
-        NOTE: when zdrun.py is not started by root, specifying this
-        option is an error.  (XXX This may be a mistake.)
-
-        XXX The zdrun.py event log file may be opened *before*
-        setuid() is called.  Is this good or bad?

-
-    <key name="hang-around" datatype="boolean"
-	 required="no"
-	 default="false">
-      <description>
-        If this option is true, the zdrun.py process will remain even
-        when the daemon subprocess is stopped.  In this case, zdctl.py
-        will restart zdrun.py as necessary.  If this option is false,
-        zdrun.py will exit when the daemon subprocess is stopped
-        (unless zdrun.py intends to restart it).

-
-    <key name="default-to-interactive" datatype="boolean"
-	 required="no"
-	 default="true">
-      <description>
-        If this option is true, zdctl.py enters interactive mode
-        when it is invoked without a positional command argument.  If
-        it is false, you must use the -i or --interactive command line
-        option to zdctl.py to enter interactive mode.

-      <description>
-        This option specifies a log file that is the default target of

-
-        NOTE: This is NOT the log file to which zdrun.py writes its
-        logging messages!  That log file is specified by the
