[M] Change in libosmocore[master]: omo_io: poll: Support multiple iov on all read/write variants
by pespin 13 Jan '26

13 Jan '26

pespin has submitted this change. ( https://gerrit.osmocom.org/c/libosmocore/+/41832?usp=email ) Change subject: omo_io: poll: Support multiple iov on all read/write variants ...................................................................... omo_io: poll: Support multiple iov on all read/write variants The logic was already in place for io_uring, but was missing for poll backend. So this patch mainly takes the existing logic from there and adapts it to poll. This way we can get some easy optimizations even when using poll(), for programs doing multiple msgb sends on the same event loop iteration.

by osmith 13 Jan '26

osmith has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-ci/+/41833?usp=email ) Change subject: scripts/manuals: use debian-trixie-build ...................................................................... scripts/manuals: use debian-trixie-build Fix that the Osmocom-release-manuals job was still using debian-bookworm-build instead of debian-trixie-build to build the manuals. We use the latter for building manuals in master-builds and gerrit-verifications. Without this patch building pyosmocom manuals failed with the following, as python3-typing-extensions in debian bookworm is at version 4.4.0 but typing_extensions >= 4.6.0 is needed for TypeAliasType. Trixie has version 4.13.2. AttributeError: module 'typing_extensions' has no attribute 'TypeAliasType'. Did you mean: 'TypeAlias'?
