"""Complicated notification for CVS checkins.
|
||
|
||
This script is used to provide email notifications of changes to the CVS
|
||
repository. These email changes will include context diffs of the changes.
|
||
Really big diffs will be trimmed.
|
||
|
||
This script is run from a CVS loginfo file (see $CVSROOT/CVSROOT/loginfo). To
|
||
set this up, create a loginfo entry that looks something like this:
|
||
|
||
mymodule /path/to/this/script %%s some-email-addr@your.domain
|
||
|
||
In this example, whenever a checkin that matches `mymodule' is made, this
|
||
script is invoked, which will generate the diff containing email, and send it
|
||
to some-email-addr@your.domain.
|
||
|
||
Note: This module used to also do repository synchronizations via
|
||
rsync-over-ssh, but since the repository has been moved to SourceForge,
|
||
this is no longer necessary. The syncing functionality has been ripped
|
||
out in the 3.0, which simplifies it considerably. Access the 2.x versions
|
||
to refer to this functionality. Because of this, the script is misnamed.
|
||
|
||
It no longer makes sense to run this script from the command line. Doing so
|
||
will only print out this usage information.
|
||
|
||
Usage:
|
||
|
||
%(PROGRAM)s [options] <%%S> email-addr [email-addr ...]
|
||
|
||
Where options are:
|
||
|
||
--cvsroot=<path>
|
||
Use <path> as the environment variable CVSROOT. Otherwise this
|
||
variable must exist in the environment.
|
||
|
||
--context=#
|
||
-C #
|
||
Include # lines of context around lines that differ (default: 2).
|
||
|
||
-c
|
||
Produce a context diff (default).
|
||
|
||
-m hostname
|
||
--mailhost hostname
|
||
The hostname of an available SMTP server. The default is
|
||
'localhost'.
|
||
|
||
-u
|
||
Produce a unified diff (smaller).
|
||
|
||
-S TEXT
|
||
--subject-prefix=TEXT
|
||
Prepend TEXT to the email subject line.
|
||
|
||
-R ADDR
|
||
--reply-to=ADDR
|
||
Add a "Reply-To: ADDR" header to the email message.
|
||
|
||
--charset=charset
|
||
Add a encoding header to message.
|
||
|
||
--quiet / -q
|
||
Don't print as much status to stdout.
|
||
|
||
--fromhost=hostname
|
||
-f hostname
|
||
The hostname that email messages appear to be coming from. The From:
|
||
header of the outgoing message will look like user@hostname. By
|
||
default, hostname is the machine's fully qualified domain name.
|
||
|
||
--help / -h
|
||
Print this text.
|
||
|
||
The rest of the command line arguments are:
|
||
|
||
<%%S>
|
||
CVS %%s loginfo expansion. When invoked by CVS, this will be a single
|
||
string containing the directory the checkin is being made in, relative
|
||
to $CVSROOT, followed by the list of files that are changing. If the
|
||
%%s in the loginfo file is %%{sVv}, context diffs for each of the
|
||
modified files are included in any email messages that are generated.
|
||
|
||
email-addrs
|
||
At least one email address.
