Telling CVS to notify you

You can tell CVS that you want to receive notifications about various actions taken on a file. You can do this without using cvs watch on for the file, but generally you will want to use cvs watch on, so that developers use the cvs edit command.

Command: cvs watch add [-a action] [-l] files ...

Add the current user to the list of people to receive notification of work done on files.

The -a option specifies what kinds of events CVS should notify the user about. action is one of the following:

edit

Another user has applied the cvs edit command (described below) to a file.

unedit

Another user has applied the cvs unedit command (described below) or the cvs release command to a file, or has deleted the file and allowed cvs update to recreate it.

commit

Another user has committed changes to a file.

all

All of the above.

none

None of the above. (This is useful with cvs edit, described below.)

The -a option may appear more than once, or not at all. If omitted, the action defaults to all.

The files and -l option are processed as for the cvs watch commands.

Command: cvs watch remove [-a action] [-l] files ...

Remove a notification request established using cvs watch add; the arguments are the same. If the -a option is present, only watches for the specified actions are removed.

When the conditions exist for notification, CVS calls the `notify' administrative file. Edit `notify' as one edits the other administrative files (see section The administrative files). This file follows the usual conventions for administrative files (see section The common syntax), where each line is a regular expression followed by a command to execute. The command should contain a single ocurrence of `%s' which will be replaced by the user to notify; the rest of the information regarding the notification will be supplied to the command on standard input. The standard thing to put in the notify file is the single line:

ALL mail %s -s \"CVS notification\"

This causes users to be notified by electronic mail.

Note that if you set this up in the straightforward way, users receive notifications on the server machine. One could of course write a `notify' script which directed notifications elsewhere, but to make this easy, CVS allows you to associate a notification address for each user. To do so create a file `users' in `CVSROOT' with a line for each user in the format user:value. Then instead of passing the name of the user to be notified to `notify', CVS will pass the value (normally an email address on some other machine).
