Bug#389061: devscripts: [new script] checkdiffs: Helpful wrapper around debdiff
Package: devscripts Version: 2.9.21 Severity: wishlist Hi, I have written a new script that I think would be good for inclusion in devscripts. I'm not sure about the name, and perhaps it should be folded in to debdiff itself, but this felt more natural. It is a wrapper around debdiff that runs it for all binary packages built from a source package, comparing the most recent version to the previous. It attempts to get as much information as possible from files. It can be run from an unpacked source dir, in which it read debian/control and debian/changelog to get the packages and versions. The alternative is to run it with a .changes file as an argument, in which case the old version must be provided, as it is not in the file. It first build a list of packages, and then downloads the packages it needs using aptitude, then compares each in turn. If you already have the binary packages on your system you can poit it to their location to save that step. I think it is worth including as it works out versions an packages from the information that is already there. It also downloads any packages that it needs, saving another manual step. I use it after a pbuilder run, so I do $ pdebuild $ checkdiffs --new-dir /path/to/pbuilder/result/dir making it very easy to use debdiff, and so try and eliminate mistakes like files going missing between versions. Please consider including it, Thanks, James diff -Nru devscripts-2.9.21/checkdiffs.1 devscripts-2.9.22/checkdiffs.1 --- devscripts-2.9.21/checkdiffs.1 1970-01-01 01:00:00.0 +0100 +++ devscripts-2.9.22/checkdiffs.1 2006-09-23 17:25:19.0 +0100 @@ -0,0 +1,38 @@ +.TH USCAN 1 "Debian Utilities" "DEBIAN" \" -*- nroff -*- +.SH NAME +checkdiffs \- run debdiff for all binary packages built from the same source +.SH SYNOPSIS +\fBcheckdiffs\fR [\fI--new-dir path\fR] [\fI--old-dir path\fR] + [\fI--old-version version\fR] [\fI--new-version version\fR] + [ .changes ] +.SH DESCRIPTION +\fBcheckdiffs\fR runs debdiff for each binary package built from a source +package, comparing the current version to the previous.

The way I always use debdiff is: apt-get source foo cd foo-1.2 dch -v1.2-1.1 cd ../ dpkg-source -b foo-1.2 Now, there will be two .dsc files, for -1 and -1.1, so you feed both to debdiff.

Yes this does work, I just wanted to expand it a little to make it easier. As was noted debdiff also deals with binary packages, but in your case you only have one set. This script finds all of the binary packages that are built by looking in debian/control. It then downloads these binary packages using aptitude for both versions (or uses ones on the filesystem if you point it to them) and compares them. So my workflow is apt-get source foo cd foo-1.2 dch -v1.2-1.1 pdebuild (or similar) checkdiffs --new-dir ../ (or wherever your build scripts leaves the packages) It allows you to compare all binary packages without having to specify them, and it removes the need to get the old versions if you don't have them. I noticed that there is a patch for half of this (the compare all binary packages part) in the BTS already, so it would remove part of the need for this script. I am not that bothered about inclusion, but I wrote the thing and I thought I would see if anyone else was interested. I had given it to one person before, who was preparing the new upload of xfce (some 10 or so source packages and many binary packages), and they liked it, as it became automated to check all of their packages. At the moment it does not also compare the source packages (I was not aware debdiff could) and would probably barf if udebs were being built. I would be happy to extend it if it were considered for inclusion. > > > +.TH USCAN 1 "Debian Utilities" "DEBIAN" \" -*- nroff -*- > > USCAN? :) oops, thanks for pointing this out. It should of course be checkdiffs.

I am not at all opposed to it. Your script looks interesting and actually seems like a step up from debdiff. -- .''`. martin f. krafft <[EMAIL PROTECTED]> : :' : proud Debian developer, author, administrator, and user `. `'` http://people.debian.org/~madduck - http://debiansystem.info `- Debian - when you have better things to do than fixing systems signature.asc Description: Digital signature (GPG/PGP)

The package keeps on getting more and more useful to me, just from looking what it can already do. I will then make a couple of tweaks to the script at some point, but I have no idea when. If anyone is interested in seeing this included I suggest you send a mail to the bug, and copy me, and say so, then I will take that as a prod to actually clean it up so it can be considered for inclusion. -- James Westby --GPG Key ID: B577FE13-- http://jameswestby.net/ seccure key - (3+)k7|M*edCX/.A:n*N!>|&7U.L#9E)Tu)T0>AM - secp256r1/nistp256 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
