those packages, but if we then try to apt-get-update those later on, this leads

I noticed this problem too, when I accidentally built a package
I already had uploaded (and totally forgotten about): basically,
the new *.deb files are accepted but the Packages file still
contains the checksums etc. from the old *.deb file.
Only way to fix this is to reupload the old *.changes file, or
to do a binNMU proper. Or to build a newer version, ofc…
So, I'm anxious, that if I start the buildd, it will happily build and upload
packages
which we already uploaded to debian-ports. If this happens we will get more
size-mismatch errors.
That’s what you have wanna-build for. Basically, stop doing
manual uploads without wanna-build locking at least six hours
before turning on the first buildd. After that time, when you
want/need to build a package manually, lock it in wanna-build:
either “take” it for building, or mark as N-F-U.
See here for more info on that:
• https://wiki.debian.org/M68k/Porting#binNMU_notes
• http://lists.debian.org/debian-68k/2012/12/msg00124.html
• http://lists.debian.org/debian-68k/2013/10/msg00021.html
If you have packages that buildds should never build, for example
like we had gcc-4.{6,8} for some time, mark them as Not-For-Us;
otherwise, just take them for building.
deller@leda:~$ wb info hello . hppa
This the same as “wanna-build -A hppa -d unstable --info hello”.
But on http://ftp.debian-ports.org/debian/pool-hppa/main/h/hello/ you can
see, that the hello-package is already uploaded at version 2.8-4
Indeed. This is bad, new, another / a different problem, and we
didn’t have this on m68k. (Note that uploads usually take a bit
until they show up on w-b, hence the need for locking.)
So, if my buildd now uploads the newly created hello package, I'm sure
we will run again into the size-mismatch problem.
Yes, you will definitely run into that problem when you upload
hello_2.8-4_hppa again.
My question here on the list would be, if you (other arch-porters) do have an
idea
on how I should proceed.
Either…
Best solution would probably be, if the wanna-build database rescans what's in
the archive already. Is this possible?
… that (no idea if it’s possible), or make two lists: a list of what
is currently in the archive for hppa, and a list of packages in the
Needs-Build or BD-Uninstallable¹ state. Then, for every package in
the same versions (except +b* sufficēs) in *both* lists, schedule a
binNMU (e.g. to get hello_2.8-4+b1_hppa). Do note whether it already
got a binNMU suffix: e.g. aclock.app_0.2.3-3+b4 would need to be
scheduled for --binNMU=5 to be larger.
You might be able to cheat, e.g. take hello for building, then tell
it that you uploaded it. But I don’t know why w-b doesn’t register
that it’s there in the first place, so a rescan, if possible, should
happen first.
Hm, only 12 packages here:
tg@leda:~$ wanna-build -A hppa -d unstable --list=needs-build | less
But this has more (9043):
tg@leda:~$ wanna-build -A hppa -d unstable --list=bd-uninstallable | less
① You need to include BD-Uninstallable because they will happily
convert to Needs-Build once you upload e.g. perl.
Or, should I just start the buildd and see what's happening? If we then get
No, get the w-b list consistent first.
According to
http://ftp.debian-ports.org/debian/dists/unstable/main/binary-hppa/Packages.bz2
hello is at version 2.8-4 just fine… hmm. So the apt-ftparchive database
seems to be correct.
This is all quite complicated, so feel free to ask around when we
can help you out again, no need for every arch to go through all
of this by themselves, figure out best practices again, etc.

Helge Thanks Helge, I'll just put the A500 on standby for a while until things stabilize a bit. I saw Thorsten Glaser's comments over in the debian-ports list, and although it doesn't make a whole lot of sense to me, since I don't fully understand how packages get processed at the repository when the buildd server uploads (or somebody manually uploads). It seems odd that debian-ports would accept a package with the same name/version number... unless it's looking at the md5 signature instead of the filename?? Is that even possible? I would think those would be unique for each file uploaded. Might be a solution to rework things where the server would look at the filename *and* the md5 sig to determine if the filename would need to be auto-incremented to the next iteration/update (e.g. hello-2.1.1-1 to hello-2.1.1-2) Just a thought...

Yes, we did correct binNMU uploads for packages which already existed
in the same version in the repo. But there were lots of packages which
were outdated (the hppa build servers stopped in 2011!) and for those
we just rebuilt from current source and uploaded with the current

Before Aurelien's answer I was thinking if this could work on leda too:
touch -d2013-01-01 ~/ref

Basically it would just try to find all packages (.changes) which
we uploaded after january 2012. Then in the next step maybe use the
--pretend-avail option of wb to tell it that this package is already
up-to-date. Not sure if this would work though...
