"5024 NUT-devel moderator request(s) waiting"
12:08

after moving to mailman 3?
12:08

it's the one list that has been on there for a while already

all from questionable addresses

did it start being crawled?

hm, most of those E-Mails and requests are ancient. And don't show up on the webif

very weird, they must have been migrated over, and only partially marked as dealt with

michaelni, BBB - wasn't it our previous position that we would not upstream wrappers for hardware that is not generally available?
13:09
<
JEEB >
IIRC we nope'd at certain patch sets for certain cloud providers' wrappers due to that
13:10
<
BBB >
that was my response to the earlier mailinglist discussion, but I'm not sure everyone agrees with me
13:11
<
BBB >
I think with free access they're trying to fix the "not generally available" portion, as that is not very well defined (what it means etc.)
13:14
<
JEEB >
although if it's free access that you specifically need to request and wait for etc etc...
13:22
<
BtbN >
I don't think I have any influence on that
13:24
<
BtbN >
I think the idea is that it's showing threads there, and it's not 100% clear which name it'd show. For one. Original author? Latest message?
13:24
<
BtbN >
In any case, I don't think it's a feature
13:25
<
BtbN >
I agree it'd be nice.
13:25
<
BtbN >
But it's all written in perl
13:26
<
BtbN >
so you can kinda pick your favourite, they both work in parallel
13:29
<
michaelni >
i guess someone just needs to patch the pearl with 1 line to show author names
13:30
<
BtbN >
I've also just plain installed it from debian packages
13:30
<
BtbN >
so patching it would be somewhat involved
13:30
<
michaelni >
you dont like re building debian packages ? ;)
13:31
<
BtbN >
that, and doing it in a consistent and sustainable way is hard
13:32
<
michaelni >
maintaining a debian package repo with secuirty fixes for a 1 line fix is hard ;)
13:32
<
BtbN >
It's also complete overkill
13:32
<
JEEB >
yea, pbuilder is not too hard to figure out at the end of the day, but yes - a full repo...
13:32
<
BtbN >
I'd rather just not use debian packages, and manually install it from git
13:33
<
BtbN >
then patching is easy
13:33
<
BtbN >
But still someone needs to first be able to read all that perl
13:33
<
JEEB >
at least now debian seems to have git-based tooling as well
13:34
<
michaelni >
nicolas knows perl IIRC, maybe if we ask him nicely he can change it or maybe upstream would be open to such feature
13:34
<
BtbN >
I would not bother with debian packages at all then
13:34
<
JEEB >
but yea, that set of tools never was as clear for me as the stuff used for fedora. that was just "you use fedpkg"

Lynne: get_value(&gb, ac_codebook) can return negative value which causes oob because it indexes array by this value
14:41
<
kasper93 >
also `31 - ff_clz(nb_blocks)` has to be replaced by ff_log2(), because clz(0) is invalid and ff_log2 takes care of that

BtbN: do you have an opinion on the nvidia changes to add more cuda pix fmts from early july?
16:17
<
BtbN >
I don't see the point in adding random new pix fmts if nothing uses them yet
16:17
<
BtbN >
If they come with a patch that actually makes use of them, it's a non-issue to just add them to the list
16:17
<
philipl >
BtbN: most (maybe not all?) of them are used in the scale_cuda patch
16:17
<
BtbN >
Yeah, then it's fine.

K. I'll try and look over the scale patch this week

I don't actually understand the syntax at all, everyone appears to use .* instead of *, does that mean it's regexp style, not shell-expansion style?

<jamrial> Traneptora: what's the reason you overwrite the Orientation tag in exif after converting it to displaymatrix side data?
18:52
<
Traneptora >
it was recommended to me on the ML after I submitted the first patch, lemme find the relevant mail link
18:53
<
jamrial >
IMO, it should be either left as is, or removed. Otherwise there will be conflicting values for the same property
18:54
<
Traneptora >
you think it should be removed entirely rather than zeroed? that makes sense
18:55
<
jamrial >
Orientation == 1 means no rotation, right? that's still a conflicting value to whatever is in display_matrix
18:56
<
jamrial >
no Orientation tag at all is undefined, so display_matrix is the only thing defining rotation
18:56
<
Traneptora >
yea, I can patch that
18:56
<
jamrial >
i already did, will make a PR later
19:02
<
Traneptora >
I'll also send a patch for a few of those CIDs probably either today or tomorrow
19:02
<
Traneptora >
been busy with $dayjob

a few are false positives, but at least one is legit

so if it's approved, I can merge it, right?
19:48
<
BBB >
or am I missing some custom?
19:49
<
jamrial >
yes, with one approval you can click the merge/rebase button
19:49
<
BBB >
it says "rebase then fast-forward", that one?
19:49
<
BBB >
and that merges?
19:50
<
jamrial >
you need to click it twice for some reason, to confirm your choice
19:50
<
BBB >
hey it worked
19:51
<
jamrial >
was the branch up to date, or did it rebase?
19:51
<
jamrial >
I'd expect a rebase to first run through CI before merging
19:52
<
BBB >
it said rebase but it did not re-run ci, I think
19:52
<
beastd >
BBB: Sorry for being late. Why did you remove wbs there? libavfilter/aarch64/.* @mstorsjo

libavcodec has simd at the end, avfilter had it inline with the c code
19:52

so I moved simd to the end for libavfilter also, including him
19:53

ah ok, thought we did alphabetic. but that also makes sense

right, it was inconsistent and I agree either way would've been fine
