Change in osmo-bsc[master]: fix performance for chan_counts and all_allocated stats

by neels

neels has submitted this change. ( https://gerrit.osmocom.org/c/osmo-bsc/+/28205 ) Change subject: fix performance for chan_counts and all_allocated stats ...................................................................... fix performance for chan_counts and all_allocated stats The all_allocated_update_bsc() does inefficient iterating to count active/inactive lchans, which scales badly for high numbers of TRX managed by osmo-bsc. We need to update the all_allocated flags immediately (periodic counting alone would suffer from undersampling), so, until now, we are calling this inefficient function every time a channel state changes. Instead of iterating all channels for any chan state changes anywhere, keep global state of the current channel counts, and on channel state change only update those ts, trx, bts counts that actually change. A desirable side effect: for connection stats and handover decision 2, we can now also use the globally updated channel counts and save a bunch of inefficient iterations. To get accurate channel counts at all times, spread around some chan_counts_ts_update() calls in pivotal places. It re-counts the given timeslot and cascades counter changes, iff required. Just in case I missed some channel accounting, still run an inefficient iterating count regularly that detects errors, logs them and fixes them. No real harm done if such error appears. None show in ttcn3 BSC_Tests. It is fine to do the inefficient iteration once per second; channel state changes can realistically happen hundreds of times per second.

Change in osmo-bsc[master]: drop log from ts_is_usable()

by neels

( https://gerrit.osmocom.org/c/osmo-bsc/+/28203 ) Change subject: drop log from ts_is_usable() ...................................................................... drop log from ts_is_usable() ts_is_usable() returns the current state; logging is the job of calling functions.

Change in osmo-bsc[master]: code cleanup for all_allocated timers, no functional change

Change in pysim[master]: commands: add ".." notation to expand hexstrings

by dexter

dexter has uploaded this change for review.
