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 (aa148d0a0734d1cec5d588b20f81e1702c4014b9) \ N -- N -- N (27d9f3e9d45a7f7be15cd1b602cb94f8ab057c3e) 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/osmo-pcu/commit/?id=27d9f3e9d45a7f7be15cd1b602cb94f… commit 27d9f3e9d45a7f7be15cd1b602cb94f8ab057c3e Author: Jacob Erlbeck &lt;jerlbeck(a)sysmocom.de&gt; Date: Tue Jul 14 14:29:34 2015 +0200 pcu: Use alloc_algorithm_dynamic by default The dynamic algorithm behaves like B until there are no TFI left.

Basically algorithm B will be selected if the PDCH usage is low to improve throughput and latency. Algorithm A will be selected to support more concurrent MS. This commit adds a first simple state-less version of this algorithm that always tries B first and only if that fails A is tried afterwards.

To implement an algorithm that dynamically tries another algorithm on failure (e.g. A after B), the first (failing) algorithm should not change or damage anything. This commit refactors algorithm A and B to delay the actual allocation until it is known that the allocation will not fail.

If this was for an DL TBF, the first common TS was selected, otherwise the least used common TS was selected for an UL TBF. The shrinking of the UL set (to 1<<first_common_ts) is done in the latter case. This commit removes an additional code path that aligns the UL set to first_common_ts, because it has no more influence on the set of common TS after both UL and DL TBF have been allocated.

This scenario is not covered by the existing tests. This commit adds a test, that allocates as man as possible TBFs several times with different test modes without clearing the BTS (and thus the TBF list) in between. The number of allocated DL TBFs in each round is expected to be constant.

This make it difficult to interleave the TBF allocation like it happens with real MS. This commit refactors the allocation loop into alloc_many_tbfs and adds support for TLLIs, which are derived from the counter value and used to retrieve an old MS object if alloc_many_tbfs is called a second time. Note that this does not make a difference for the existing tests.

This patch adds a is_idle() method that will return true if the MS object is just kept by the guard from being idle. In that case, the MS object would either be deleted or return true for GprsMs::is_idle() after the guard's destruction, provided that no TBF attachment took place in between.

TBFs can be searched globally by TFI and TRX number. This conflicts with the use of the same TFI for different TBF on different PDCH. This use case requires the specification of the PDCH as additional search dimension. This commit moves the TFI index TBF arrays into the PDCH objects. The related methods are updated accordingly.

This commit modifies algorithm_a() to allow the sharing of TFI between different PDCH. Since algorithm A only assigns a single slot to each TBF, the TFI of each PDCH can be assigned independently. This increases the maximum to 32 TBF per direction and per PDCH concerning the TFI allocation.

This does fit to TFI reuse for different slots, since this were tightly coupled with the slot selection. This commit just moves the TFI selection into the alloc_algorithm functions. The tfi parameter is removed from the the TFI alloc functions. The trx parameter is changed into use_trx to optionally limit the trx selection (same semantics like in tfi_find_free).

It iterates through all TBFs, records on which PDCH it uses which TFI and check for conflicts. It also checks the bits returned by pdch->assigned_tfi(). The latter suffers from an bug in that method (no separation of uplink and downlink), so a conditional fprintf is used instead of an assertion. The method tfi_find_free is checked for conflicts after allocations.
