I'm not super familiar with the changelog files, but they seem to have
a well defined format, so we should first look if there already are
parsers. So it might be fine to keep the regular changelog format, and
use a parser whenever we want to process the data. Checking if the
changelog syntax is correct can be part of package checking.
There is a parser in cswch (nothing official, I hacked it together),
which
tries to be compliant with [1]. So cswch has a pretty good idea of
changelog.CSW and it should be trivial to convert changelog.CSW into
any other
format. Let me know what you need.
I also had this idea that instead of using VERSION in the Makefile, we
could take the latest version from changelog:
VERSION = $(call extract_version_from_changelog)
+1
[1]
http://www.debian.org/doc/debian-policy/ch-source.html#s-dpkgchangelog
I don't think that is a good idea for two reasons:
1. The application version (e.g. 1.2) is tightly coupled to DISTFILE and
updated only on version bumps.
2. The REV is calculated from the date which is good IMHO
The Changelog should IMHO contain high-level descriptions of changes,
like
"Switch from OpenSSL to GnuTLS" accommodated by a date when the change
was
done. This may not be related to package rebuilds.
What may be a good idea is to retrieve the REV timestamp from the change
log,
but again rebuilding may result in binary-different packages with the
same
revstamp.
One related thing: It would be nice if we could enable the catalog
versions
on the webpage and have a "svn diff" button between REVs to show the
Makefile
diffs as calculated by OpenGrok.
