Re: Description-less packages file
Hi Stuart,
I just applied your patch on the UDD clone at blends.debian.net.

Just commited after testing.

That's correct and the inclusion of the Description-md5 field is quite
fortunate because it looks promising that I can drop the hackish
workaround using mapping via the Version field which some kind soul from
UDD people (Michael Grisu Bramer) provided in a specific dedicated
location at ddtp.debian.net (which is not reliably online
unfortunately).

Yes.

I wonder how many applications are actually using the long_description
field. All these applications might be currently broken and I wonder
whether anybody has noticed this breakage.

While your patch is working it is actually not helpfull in all cases:
udd=# SELECT distribution, release, count(*) from packages where description_md5 is not null group by distribution, release;
distribution | release | count
--------------+--------------+--------
debian | sid | 277961
debian | experimental | 17792
(2 rows)
udd=# SELECT distribution, release, count(*) from packages where description_md5 is null group by distribution, release;
distribution | release | count
-------------------------+--------------------------+--------
debian-backports | squeeze | 10196
lenny-volatile-proposed | lenny | 205
debian | squeeze | 189547
debian | wheezy-proposed-updates | 108
debian | squeeze-proposed-updates | 321
debian | wheezy | 247064
debian | lenny-proposed-updates | 3054
debian-backports-sloppy | lenny | 409
debian | lenny-security | 13089
lenny-volatile | lenny | 127
debian | squeeze-security | 6348
debian-backports | lenny | 16196
debian | squeeze-updates | 235
debian | lenny | 171861
(14 rows)
So we have only description_md5 fields filled for sid and experimental.
It is lacking for all other releases and I honestly wonder whom to ask
to include this in *all* packages files without any exception.
So, yes, I will try to fix ddtp gatherer over this weekend but that's
only half of the solution without complete Description-md5 fields in
*all* packages files. I can try to work around this because it turns
out that the description_md5 field is only needed really in case there
are different descriptions for different architectures / versions which
is not that frequently the case. So the import of the English
translations could be done to some extend - but the problem is not
fully solvable in the current state.
Kind regards
Andreas.
