information in the versioncache file, located in the data/ subdirectory
under your installation directory.

(the versions table for example), or to the
<SPAN
CLASS="QUOTE"
>"constants"</SPAN
> encoded in defparams.pl, you will
need to remove the cached content from the data directory
(by doing a <SPAN
CLASS="QUOTE"
>"rm data/versioncache"</SPAN
>), or your
changes won't show up.
</P
><P
> That file gets automatically regenerated whenever it's more than an
hour old, so Bugzilla will eventually notice your changes by itself, but
generally you want it to notice right away, so that you can test things.

fields. You'll get SQL errors if you just update the code. The strategy
to update is to simply always run the checksetup.pl script whenever
you upgrade your installation of Bugzilla. If you want to see what has
changed, you can read the comments in that file, starting from the end.
</P

the latest version, please consult the file, "UPGRADING-pre-2.8" in the

<ry4an@ry4an.org>, with some edits by Terry Weissman, Bryce Nesbitt,
Martin Pool, & Dan Mosedale (But don't send bug reports to them;
report them using bugzilla, at http://bugzilla.mozilla.org/enter_bug.cgi ,
project Webtools, component Bugzilla).
</P

reflect changes for Bugzilla 2.12 release by Matthew P. Barnson. The
securing MySQL section should be changed to become standard procedure
for Bugzilla installations.
</P

the Guide on April 24, 2001 by Matt Barnson. Since that time, it's undergone
extensive modification as Bugzilla grew.
