( https://gerrit.osmocom.org/c/libosmocore/+/20296 ) Change subject: logging: Change stderr + file target to use non-blocking write ...................................................................... Patch Set 9: (2 comments) https://gerrit.osmocom.org/c/libosmocore/+/20296/4/src/logging.c File src/logging.c: https://gerrit.osmocom.org/c/libosmocore/+/20296/4/src/logging.c@926 PS4, Line 926: if (rc != msgb_length(msg)) > Well that's maybe the issue here. […] There's a trade-off here. If we write too many msgb's within one select cycle, we might be starving other I/O as we implicitly set a higher priority to LOG output (write multiple msgb per cycle) over protocol I/O (write one msgb per cycle for RSL, SCCP, ...). Sure, we could have an upper bound (like 10?). Let's leave that for a follow-up patch. https://gerrit.osmocom.org/c/libosmocore/+/20296/4/src/select.c File src/select.c: https://gerrit.osmocom.org/c/libosmocore/+/20296/4/src/select.c@283 PS4, Line 283: log_target_file_switch_to_wqueue(osmo_stderr_target); > There's a use case: debugging. […] This has been adressed in the latest revision, see the changelog. There's now no automatic unconditional switch to non-blocking from osmo_select_main() anymore. Rather, it depends on VTY and API usage. -- To view, visit https://gerrit.osmocom.org/c/libosmocore/+/20296 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: libosmocore Gerrit-Branch: master Gerrit-Change-Id: Ia58fd78535c41b3da3aeb7733aadc785ace610da Gerrit-Change-Number: 20296 Gerrit-PatchSet: 9 Gerrit-Owner: laforge <laforge at osmocom.org> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: laforge <laforge at osmocom.org> Gerrit-CC: pespin <pespin at sysmocom.de> Gerrit-Comment-Date: Thu, 08 Oct 2020 16:16:06 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: laforge <laforge at osmocom.org> Comment-In-Reply-To: pespin <pespin at sysmocom.de> Gerrit-MessageType: comment -------------- next part -------------- An HTML attachment was scrubbed...
