Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Here is the list of all changes to our libraries for the Blender 4.0 release.
there is no temp branch yet for the 4.0 lib work

install_linux_packagesscript (N/A)USD 23.05 - no version change, repo got renamed from USD to OpenUSD leading to a URI and package Hash change

install_linux_packagesscriptOpenSSL 3.0.9
install_linux_packagesscript (N/A)@mont29 USD recently renamed them selves to OpenUSD leading to an URI/Hash change for the existing 23.05 release, unsure if that's relevant for the linux script, so i'm just pinging you so you're aware.
@LazyDodo Ah thanks, for the heads up. Think the script remains unaffected by that (for now at least), since as far as I can tell neither Fedora nor Arch have updated their package names... Will have to keep an eye on that.
We're bumping llvm to 15.0.x this will likely cause some clang-format changes, so landing this will need some coordination between the platform teams and core to have it all go over smoothly. Unsure how to go about this yet, @ideasman42 given you're on both teams and have a good handle on clang-format can you look into the ramifications of bumping to v15 (for clang format only, OSL being the only other consumer should be ok according to their documentation )
@LazyDodo bumping LLVM to 15.0.7 seems fine, is anything needed from my side?
IGC_LLVM_VERSIONbe bumped too?My main ask is for you to check out the formatting changes clang-format does with the V15 version as i'm not familiar enough with how this was setup, so i honestly don't know if it's wrong and needs a .clang-format change or it's doing a better job than v12 and everything is ok already.
Ah, the formatting changes are good as far as I'm concerned.
embree 4.1.0 rebuild with additional patch to resolve a crasher has been added, platform devs please rebuild main when convenient. (this is still in the pipeline for 3.6 as well, but please wait till the patch has landed there, i will add a work item in #104895 for that once the patch landed there)
We will want to rebuild USD for #110474, but not yet since we may discover more issues to be fixed.
When it's ready, just add it to the starting post, I'll take that as it being an actionable work item.
Slightly related to this, historically we kept a list of changes/new/preliminary libs which when a dep needed a second rebuild in a cycle we'd just clear the checkmarks. I'm considering of moving that over to a
todo / wip / done- style list.In order to
keep some history on LTS releases where the ticket be alive for 2+ years and odds of updating a single dep multiple times (cough python security releases cough) is relatively high, it be good to keep a historic list on when certain work items were completed.
It's nice to have an open work item list near the top of the ticket and a whole bunch of stuff you can ignore nicely separated into its own section
@brecht / @ideasman42 either of you have strong opinions on this?
It's fine with me to separate things like that.
This also seems fine to me.
Regarding the remaining library updates for 4.0, which I think we prefer to before Bcon3 (in less than 2 weeks).
LLVM 15 seems to be the only one that is listed but has no corresponding CMake changes yet. I propose to move that to Blender 4.1 unless there is a specific reason we should upgrade now?
Assuming that's the case, Linux seems to be up to date and for macOS I would only need to update SDL. For Windows there are more libraries to be updated, which I guess @LazyDodo will have time for still?
llvm changes are in #110708 it was done mostly as a favor for the linaro people, i'm ok bumping to 4.1, especially since i saw a critical CVE fly by for zlib that may require a significant time allocation
Feel free to revert
607adbca47if LLVM 15 is postponed (not critical, but better be consistent).I'd like to mention the following 3 updates for consideration:
@deadpin which OIIO patch are you referring to?
@brecht Need to create a patch from this PR: https://github.com/OpenImageIO/oiio/pull/3984
handy shortcut, you can just add .diff to the end of any github pull
https://github.com/OpenImageIO/oiio/pull/3984.diff
(works for pulls on p.b.o as well)
@deadpin ok, I added WebP 3.1.2 and OIIO 2.4.15 + the patch in #112529 and #112528.
We follow the VFX platform, and there OpenColorIO 2.3 is planned for next year.
If it's still possible, there was another bug that came in last week that requires a small patch to OIIO:

Fixes a DDS load issue (https://github.com/OpenImageIO/oiio/issues/3993)
