Revision 1.8, Tue Jul 27 16:16:19 2004 UTC (19 years, 10 months ago) by jfb
Branch: MAIN
Changes since 1.7: +47 -14 lines
* use a mix of mktime() and ctime_r() instead of asctime_r() to calculate
the Mod-time timestamp. This way, mktime() fills in information about
the week day and day of year which was not calculated with the previous
method
* calculate the GMT offset
This fixes a bug where each CVS entry in the Entries files would have
`Sun' (for Sunday) as the day of the week.

/*
* CVS client/server protocol
* ==========================
*
* The following code implements the CVS client/server protocol, which is
* documented at the following URL:
* http://www.loria.fr/~molli/cvs/doc/cvsclient_toc.html
*
* The protocol is split up into two parts; the first part is the client side
* of things and is composed of all the response handlers, which are all named
* with a prefix of "cvs_resp_". The second part is the set of request
* handlers used by the server. These handlers process the request and
* generate the appropriate response to send back. The prefix for request
* handlers is "cvs_req_".
