That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this: * -- * -- B -- O -- O -- O (8ea535d406279b9f651c0030b89c94a13fe57d3b) \ N -- N -- N (383521ab51181f2d48d0775c1253a0f2b58ef637) When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B. Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- http://cgit.osmocom.org/openbsc/commit/?id=383521ab51181f2d48d0775c1253a0f2… commit 383521ab51181f2d48d0775c1253a0f2b58ef637 Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Tue Jun 14 01:32:46 2016 +0200 debug log: log all lchan_alloc steps Change-Id: Ib2d11744d92dc06205fb1573815e11efd84842b0 http://cgit.osmocom.org/openbsc/commit/?id=093badbc4a980d928f39083437692d8b… commit 093badbc4a980d928f39083437692d8b79843da6 Author: Neels Hofmeyr <neels(a)hofmeyr.de> Date: Sat Jul 23 20:15:28 2016 +0200 dyn TS: OS#1778 workaround: disable TCH/F on dyn TS To avoid two phones picking mismatching TCH pchans, disable TCH/F on dynamic pchans for now.

These save the Channel Requested details across the PDCH deactivation dance. abis_rsl.c: add static functions: * dyn_ts_switchover*() for the various stages of switchover between pchans. * pchan_for_lchant() to derive the desired pchan from the lchan type that was set during lchan_alloc(). * rsl_chan_activate_lchan_as_pdch() to compose the simpler RSL CHAN ACT message without introducing numerous special cases to the normal RSL CHAN ACT code. In rsl_chan_activate_lchan(), detect and initiate required pchan switchovers if requested pchan on a dyn TS differs. In rsl_rx_rf_chan_rel_ack(), initiate or continue pchan switchovers after a channel was released. In rsl_rx_chan_act_ack(), notice that a switchover is complete.

The subslots_per_pchan[] array is static to lchan_alloc.c, and since we need a check for dyn TS anyway, add public ts_subslots() to lchan_alloc.c, which also checks the current dyn pchan type.

Add _lc_find_bts() as wrapper so non-dynamic-TS callers remain unchanged. Also add dyn_as_pchan arg to _lc_find_trx() (not renaming to dyn and wrapping because there is only one caller). Implement dynamic allocator logic in _lc_find_trx() and lchan_alloc(). A returned dynamic channel still needs to be switched to the proper mode, which will follow in another commit. Replace a fixme comment with a normal comment in subslots_per_pchan[], because handling of dynamic TS is now defined.

So in order to pass the desired pchan to generate the RSL chan_nr, introduce gsm_lchan_as_pchan2chan_nr(). To avoid code dup, this requires decoupling the gsm_ts2chan_nr() pchan from the actual ts struct, so refactor gsm_ts2chan_nr() to gsm_pchan2chan_nr() with explicit pchan, ts_nr and lchan_nr arguments.

Factor out the common code to rsl_lchan_lookup() in gsm_data_shared.c. Openbsc and osmo-bts each define their own DRSL log constant, so add an int *rc return code argument and keep the logging part in abis_rsl.c's thin lchan_lookup() wrapper. Incidentally, this also removes code dup for logging. To avoid duplicate symbols, the rsl_lchan_lookup() implementation needs to be removed from osmo-bts, so older osmo-bts git revisions will not build with this.
