[M] Change in osmo-bts[master]: Rewrite pcu_sock_write()

by pespin

Attention is currently required from: osmith, arehbein. Hello osmith, Jenkins Builder, arehbein, fixeria, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-bts/+/31924 to look at the new patch set (#2). Change subject: Rewrite pcu_sock_write() ...................................................................... Rewrite pcu_sock_write() The code in that function is pretty rotten: * osmo_fd_write_disable() is called for each message in the queue, there's no need for that. Let's simply call it at the end if the queue is empty. * Asserting for obvious stuff like dequeue returning the first entry in the list. * Having error code path for empty message: That shouldn't happen, abort immediately. With all thse changes, the function is way simpler, easy to read and more efficient.

I see that this can be done in the previous because it's inside a while(!llist_empty()) loop, but then it makes no sense to call it on every loop iteration. In this new code here, you cannot do that. > Probably isn't noticeable because sooner or later, the enable happens, anyways. Yes, next time a packet is enqueued. That doesn't mean it's correct though.

I have looked at some of our projects and seen similar code (code that disables the fd before calling `write` or transmitting data (probably also ultimately calling write) in osmo-trx, osmo-bts and libosmo-abis code. Probably isn't noticeable because sooner or later, the enable happens, anyways. Should I still change the code so that the fd is disabled only when there is no data to write anymore (and enabled after data is added to the msg queue)? -- To view, visit https://gerrit.osmocom.org/c/osmo-bts/+/31533 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: osmo-bts Gerrit-Branch: master Gerrit-Change-Id: Ia6e61dda4b3cd4bba76e6acb7771d70335062fe1 Gerrit-Change-Number: 31533 Gerrit-PatchSet: 5 Gerrit-Owner: arehbein <arehbein(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: pespin <pespin(a)sysmocom.de> Gerrit-CC: fixeria <vyanitskiy(a)sysmocom.de> Gerrit-CC: laforge <laforge(a)osmocom.org> Gerrit-Attention: laforge <laforge(a)osmocom.org> Gerrit-Attention: fixeria <vyanitskiy(a)sysmocom.de> Gerrit-Attention: pespin <pespin(a)sysmocom.de> Gerrit-Comment-Date: Wed, 15 Mar 2023 15:48:15 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: arehbein <arehbein(a)sysmocom.de> Comment-In-Reply-To: fixeria <vyanitskiy(a)sysmocom.de> Comment-In-Reply-To: pespin <pespin(a)sysmocom.de> Gerrit-MessageType: comment
