[02:08] <adoniscik> how do you set the name of the package with stdeb if I want to create separate packages for python2 and python3?
[02:09] <adoniscik> I want X to be renamed python-X and python3-X
[02:12] <wgrant> adoniscik: I'd examine the manual and/or code of stdeb, and then ask in #ubuntu-packaging if you still can't work it out.
[02:12] <wgrant> That's not really anything to do with Launchpad.
[02:13] <adoniscik> okay, I will ask there.
[02:17] <xnox> adoniscik: export PYBUILD_NAME=X \n %: \n \t dh $@ --with python2,python3 --buildsystem=pybuild
[02:22] <adoniscik> cool, xnox That looks like it's intended for pybuild. How does it relate to stdeb?
[07:49] <adoniscik> dput refuses to upload a deleted package that it believes "has already been uploaded"
[08:11] <wgrant> adoniscik: You need to change the version if you change the package.
[08:12] <adoniscik> wgrant, I deleted the package instead since it never built properly in hte first place. I don't see the package but dput seems to think it is there. Should I still increment the version?
[08:12] <wgrant> adoniscik: That dput check is local and can be overridden with -f, but Launchpad will reject a reuse of the same version even if you've deleted it.
[08:12] <wgrant> You must change the version if you change the package.
[08:13] <adoniscik> where is that set, Standards-Version?
[08:15] <wgrant> adoniscik: debian/changelog
[08:16] <wgrant> And you should always use dch to manipulate that.
[08:16] <wgrant> It sounds like you should read the Ubuntu packaging guide.
[08:23] <adoniscik> I edited the changelog and ran debuild again, but launchpad rejected the package because it said the file already exists. I added a letter to the version, which the rejection email indicated in the title, but ignored in the body. Weird...
[08:29] <wgrant> adoniscik: What exactly did you change it to, and what was the exact text of the error message?
[08:30] <adoniscik> from "foo (version) dist; urgency=low" to "foo (versiona) dist; urgency=low"
[08:31] <adoniscik> then I dput the new changes file, which launchpad successfully received. The email noted the new version in the title, but the old file name in the body
[08:31] <wgrant> Exact text of the error message :)
[08:32] <wgrant> Was it the orig.tar.gz?
[08:32] <adoniscik> foo_0.1.2.orig.tar.gz
[08:32] <wgrant> Also ensure you've read and understood https://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-Version
[08:32] <wgrant> Right.
[08:32] <wgrant> " The version number of a package. The format is: [epoch:]upstream_version[-debian_revision] "
[08:32] <wgrant> The orig.tar.gz is the upstream tarball, and that has the upstream version.
[08:33] <wgrant> That is anything before the final -.
[08:33] <wgrant> The orig.tar.gz is meant to be as the name suggests: the original tarball as released by upstream, bit-identical.
[08:33] <wgrant> How did upstream's release tarball change without changing the version number?
[08:35] <adoniscik> sorry, I am not sure I follow. I merely tagged an "a" to 0.1.2-1, making it 0.1.2-1a. If I follow you, this does not really constitute a version change, so it rejected it?
[08:36] <wgrant> It is a version change, but it's not an upstream version change.
[08:37] <wgrant> And it sounds like you changed the upstream tarball, so you need to change the upstream version.
[08:37] <wgrant> But how did the upstream tarball change? That normally indicates that something else has gone wrong.
[08:37] <wgrant> In your new version, upstream_version=0.1.2, debian_revision=1a.
[08:37] <adoniscik> and the old?
[08:37] <adoniscik> because I reran debuild after changing the changelog?
[08:38] <adoniscik> I thought that was how I would reflect the updated changelog
[08:38] <wgrant> The old version was upstream_version=0.1.2, debian_revision=1
[08:38] <wgrant> Running debuild won't have changed your orig.tar.gz.
[08:38] <wgrant> Debian tools don't touch it, normally, since it's meant to be identical to the one you downloaded from the upstream author.
[08:39] <adoniscik> I have 1 orig.tar.gz, and two debian.tar.gz
[08:39] <adoniscik> two source.builds
[08:39] <wgrant> Yes.
[08:39] <adoniscik> that's good, right?
[08:39] <wgrant> But if Launchpad rejected it because the orig.tar.gz conflicted, you must have changed the contents of the orig.tar.gz without changing the orig.tar.gz's version.
[08:40] <adoniscik> well it did say the file exists and "uploaded version has different contents"
[08:41] <wgrant> The upstream md5sum is 0a9c0986d9b6c1d3f88135afa3da2230
[08:41] <wgrant> That doesn't match the one you uploaded to Launchpad before.
[08:41] <wgrant> Does it match the one you have on disk now?
[08:42] <adoniscik> of the tgz?
[08:43] <adoniscik> the orig.tgz is b7532f1be6f7e034a9f04a6e47759bbb
[08:44] <adoniscik> the modified debian.tgz is 99d9aa3fc63361a73d517f1a63e61b05
[08:45] <wgrant> adoniscik: That doesn't match either the one you uploaded to Launchpad or the one on PyPI. How did you construct the two orig.tar.gzs?
[08:47] <adoniscik> i downloaded it from pypi, extracted it, ran "python setup.py --command-packages=stdeb.command sdist_dsc", edited the rules file to use pybuild, etc.
[08:48] <adoniscik> sorry for the trouble, I am trying to upload my first package :)
[08:49] <wgrant> I've not used stdeb.
[08:49] <wgrant> But if it generates an orig.tar.gz itself then that's pretty weird.
[08:49] <wgrant> In future, use the upstream-provided tar.gz instead.
[08:49] <adoniscik> I also used debuild
[08:50] <adoniscik> you mean from pypi?
[08:50] <wgrant> Yes.
[08:50] <wgrant> In this case you'll still have to change the version, since the real upstream version's filename had a bad tarball behind it.
[08:51] <wgrant> So, I would grab the orig.tar.gz from pypi, and name it something like FOO_1.2.3+upstream1.orig.tar.gz
[08:51] <wgrant> Then add a new changelog entry for version 1.2.3+upstream1-1
[08:51] <wgrant> (the "+upstream1" is just an arbitrary string to make the version larger than the old one, while also suggesting what happened)
[08:52] <adoniscik> I didn't know I could directly upload those archives. so I just need to put a copy of the tgz from pypi and rename it to foo.orig.tar.gz (i.e., add the orig)
[08:52] <wgrant> When 1.2.4 is released, ensure that you use the orig.tar.gz from PyPI instead of anything generated by stdeb.
[08:52] <wgrant> A normal Debian source package is composed of an orig.tar.gz, and debian.tar.gz, and a dsc.
[08:52] <wgrant> The orig.tar.gz is traditionally exactly the upstream release tarball.
[08:53] <wgrant> THe debian.tar.gz just contains the debian/ directory of your source package. debuild (well, dpkg-buildpackage, called by debuild) generates it by tarring up the debian/ directory.
[08:53] <wgrant> The dsc just provides metadata and the hashes of the orig.tar.gz and debian.tar.gz.
[08:53] <wgrant> You generate none of those files yourself, and debuild generates all except the orig.tar.gz.
[08:54] <wgrant> debuild works out which orig.tar.gz to use based on the latest version in debian/changelog.
[08:54] <wgrant> So if your changelog starts with "foo (1.0) trusty; urgency=low", it'll use foo_1.0.orig.tar.gz in the parent directory.
[08:55] <adoniscik> cheers, I'll try again. most informative.
[08:57] <wgrant> (note that some older or native Debian source packages have a different set of files, but none you're likely to run into)
[09:28] <adoniscik> so the package built, but only for python3, presumably since that's what I ran stdeb with. I suppose I need to run it again with python2. If I wanted to create separate packages, should I just edit the changelog to rename foo to python-foo or python3-foo?
[09:29] <adoniscik> thanks for your patience, wgrant
[09:31] <wgrant> adoniscik: AFAICR stdeb just generates debian/* from metadata in setup.py. You would normally do that once, trim any unnecessary bits, then edit the autogenerated files to meet your needs.
[09:31] <wgrant> One of those needs might be support for multiple Python versions.
[09:32] <wgrant> There's no reason to have a separate source package; it's normal and common for a single source to generate python-foo and python3-foo.
[09:32] <wgrant> See the example debian/rules that xnox gave earlier, but you'll also need to add a new Package stanza to debian/control.
[09:42] <adoniscik> oh good. where does debian/control get the contents of ${python:Depends}? I created a new stanza renaming the package and ${python3:Depends}
[09:46] <wgrant> adoniscik: https://wiki.debian.org/Python/Packaging is probably of interest.
[09:48] <wgrant> But ${python:Depends} is a "substvar". Check the dh_python2 manpage for details of the substvars it provides.
