<title>PostgreSQL: Getting the source via CVS</title>

<font size="+3">Getting the source via CVS</font>
|
|
|
|
<p>If you would like to keep up with the current sources on a regular
|
|
basis, you can fetch them from our CVS server and then use CVS to
|
|
retrieve updates from time to time.
|
|
|
|
<P>To do this you first need a local copy of CVS (Concurrent Version Control
|
|
System), which you can get from
|
|
<A HREF="http://www.cyclic.com/">http://www.cyclic.com/</A> or
|
|
any GNU software archive site. Currently we recommend version 1.9.
|
|
|
|
<P>Once you have installed the CVS software, do this:
|
|
<PRE>
|
|
cvs -d :pserver:anoncvs@postgresql.org:/usr/local/cvsroot login
|
|
</PRE>
|
|
You will be prompted for a password; enter '<tt>postgresql</tt>'.
|
|
You should only need to do this once, since the password will be
|
|
saved in <tt>.cvspass</tt> in your home directory.
|
|
|
|
<P>Having logged in, you are ready to fetch the PostgreSQL sources.
|
|
Do this:
|
|
<PRE>
|
|
cvs -z3 -d :pserver:anoncvs@postgresql.org:/usr/local/cvsroot co -P pgsql
|
|
</PRE>
|
|
which will install the PostgreSQL sources into a subdirectory <tt>pgsql</tt>
|
|
of the directory you are currently in.
|
|
|
|
<P>(If you have a fast link to the Internet, you may not need <tt>-z3</tt>,
|
|
which instructs CVS to use gzip compression for transferred data. But
|
|
on a modem-speed link, it's a very substantial win.)
|
|
|
|
<P>This initial checkout is a little slower than simply downloading
|
|
a <tt>tar.gz</tt> file; expect it to take 40 minutes or so if you
|
|
have a 28.8K modem. The advantage of CVS doesn't show up until you
|
|
want to update the file set later on.
|
|
|
|
<P>Whenever you want to update to the latest CVS sources, <tt>cd</tt> into
|
|
the <tt>pgsql</tt> subdirectory, and issue
|
|
<PRE>
|
|
cvs -z3 update -d -P
|
|
</PRE>
|
|
This will fetch only the changes since the last time you updated.
|
|
You can update in just a couple of minutes, typically, even over
|
|
a modem-speed line.
|
|
|
|
<P>You can save yourself some typing by making a file <tt>.cvsrc</tt>
|
|
in your home directory that contains
|
|
|
|
<PRE>
|
|
cvs -z3
|
|
update -d -P
|
|
</PRE>
|
|
|
|
This supplies the <tt>-z3</tt> option to all cvs commands, and the
|
|
<tt>-d</tt> and <tt>-P</tt> options to cvs update. Then you just have
|
|
to say
|
|
<PRE>
|
|
cvs update
|
|
</PRE>
|
|
to update your files.
|
|
|
|
<P><strong>CAUTION:</strong> some versions of CVS have a bug that
|
|
causes all checked-out files to be stored world-writable in your
|
|
directory. If you see that this has happened, you can do something like
|
|
<PRE>
|
|
chmod -R go-w pgsql
|
|
</PRE>
|
|
to set the permissions properly. This bug is allegedly fixed in the
|
|
latest beta version of CVS, 1.9.28 ... but it may have other, less
|
|
predictable bugs.
|
|
|
|
<P>CVS can do a lot of other things, such as fetching prior revisions
|
|
of the PostgreSQL sources rather than the latest development version.
|
|
For more info consult the manual that comes with CVS, or see the online
|
|
documentation at <A HREF="http://www.cyclic.com/">http://www.cyclic.com/</A>.
