The git-cvsserver script is old and largely unmaintained these days. But git-shell allows untrusted users to run it out of the box, significantly increasing its attack surface. Let's drop it from git-shell's list of internal handlers so that it cannot be run by default. This is not backwards compatible. But given the age and development activity on CVS-related parts of Git, this is likely to impact very few users, while helping many more (i.e., anybody who runs git-shell and had no intention of supporting CVS). There's no configuration mechanism in git-shell for us to add a boolean and flip it to "off". But there is a mechanism for adding custom commands, and adding CVS support here is fairly trivial. Let's document it to give guidance to anybody who really is still running cvsserver. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

# CVS LOG

|
|
|
# Known issues with git-cvsserver current log output:
|
|
# - Hard coded "lines: +2 -3" placeholder, instead of real numbers.
|
|
# - CVS normally does not internally add a blank first line
|
|
# or a last line with nothing but a space to log messages.
|
|
# - The latest cvs 1.12.x server sends +0000 timezone (with some hidden "MT"
|
|
# tagging in the protocol), and if cvs 1.12.x client sees the MT tags,
|
|
# it converts to local time zone. git-cvsserver doesn't do the +0000
|
|
# or the MT tags...
|
|
# - The latest 1.12.x releases add a "commitid:" field on to the end of the
|
|
# "date:" line (after "lines:"). Maybe we could stick git's commit id
|
|
# in it? Or does CVS expect a certain number of bits (too few for
|
|
# a full sha1)?
|
|
#
|
|
# Given the above, expect the following test to break if git-cvsserver's
|
|
# log output is improved. The test is just to ensure it doesn't
|
|
# accidentally get worse.
