Обсуждение: CVS checkout source code for different branches

Hi,<br /><br />I am trying to checkout code from different branches (such as 8.3, 8.4). <br /><br />I found a few ways
tocheckout code from CVS: <br />1. webCVS: <a
href="http://anoncvs.postgresql.org/cvsweb.cgi/">http://anoncvs.postgresql.org/cvsweb.cgi/</a><br/><br />2. cvs -z3 -d
:pserver:anoncvs:password@anoncvs.postgresql.org:/projects/cvsrootco -P pgsql<br /><br />3. $ rsync --progress -avzCH
--deleteanoncvs.postgresql.org::pgsql-cvs $CVSROOT<br /><br />However, how can I checkout code from different branches
(suchas 8.3, 8.4)?<br /><br />Thank you.<br />M Z<br />

CVS is documented here, among other places: 
<http://ximbiot.com/cvs/manual/cvs-1.11.20/cvs.html>

To check out a particular branch such as REL8_4_STABLE, use the -r 
option on the checkout command:
   cvs checkout -r branchname

The only sane things to check out apart from HEAD are normally the 
STABLE branches. For release m.n those are always called RELm_n_STABLE. 
You can also get the tag set for a specific release. Those are called 
RELm_n_o for m.n.o releases.

If you look at the output for "cvs log configure.in" you can see near 
the top a list of tag sets under the heading "symbolic names".

HTH.

REL8_3_STABLE is the head of the stable branch for 8.3.  It says 8.3.9
right now because 8.3.9 is the last release that was stamped off that
branch, but what you checked out actually has any changes backpatched
since then on it as well.

That patch hasn't been applied yet.  You have to download it from his
message and apply it to your local copy using the "patch" program.

Andrew already answered that question in his previous message: use cvs
log on a file that's been around for a long time, like configure.in.

It sounds like you need to find some documentation for CVS and read
it, and/or find a CVS help mailing list and post to it.

I've already told you how to see all the tags/branches - use the "cvs 
log" command on a longstanding file like "configure.in".

REL8_3_STABLE is the branch to develop against for the 8.3 series of 
releases. But unless you're fixing a bug it's pointless - we never add 
features to the stable branches, we only make bug fixes.  And for this 
purpose bugs are defined fairly conservatively. All feature work should 
normally be done against HEAD.

What exactly are you wanting to do with the back branches?

cheers
