andrewrk added this to the Urgent milestone 2026年05月01日 05:22:49 +02:00

Aside from the deprecations, there is a lot of work to do to update usage sites. This is a good place to get started for new contributors. Don't forget to start small!

Main blocker here is that the CI depends on @jacobly LLDB Zig fork, and those have hardcoded names with Unmanaged.
So the changes need to be made in sync with LLDB changes.

I'm facing a similar situation with #32205 where changes to private std fields need changes in zig lldb.

(I made a similar comment on PR #35196, ported here for better visibility)

std.DynamicBitSet (currently an alias for bit_set.DynamicManaged) seems to have been deprecated by 1deb029a66. The non deprecated version is bit_set.Dynamic (which is unmanaged). I think it can be checked off.
