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 (d4182120a4d37d5652ca304c9ea9c2b912bacd98) \ N -- N -- N (06a64d7db2f93a996a074cfb9e1a8eacd3303eee) 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/libosmocore/commit/?id=06a64d7db2f93a996a074cfb9e1a… commit 06a64d7db2f93a996a074cfb9e1a8eacd3303eee Author: Jacob Erlbeck &lt;jerlbeck(a)sysmocom.de&gt; Date: Thu Oct 29 00:55:58 2015 +0100 stats: Add osmo_ name prefix to identifiers Since the the stat_item and stats functions and data types are meant to be exported, they get an osmo_ prefix.

The statsd protocol expects differential counter values, which are currently not provided by rate_ctr (except for s/m/h/d intervals). This commit adds several helper functions to rate_ctr: - rate_ctr_difference returns the counter delta since the last call to this function for a given counter - rate_ctr_for_each_counter iterates through each counter of a group - rate_ctr_for_each_group iterates through all globally registered counter groups Note that the rate_ctr_difference function can only be used by a single backend, since it modifies the 'previous' field in the rate_ctr obj.

The drawback is, that such an index must be stored for each stat item. This commit introduces a global index which is incremented for each new stat item value. This index is then stored together with the item value. So a single stored index per reporter is sufficient to make sure that only new values are reported.

Multiple values can be stored per item, which can be retrieved in FIFO order. Getting values from the item does not modify its state to allow for multiple independant backends (e.g. VTY and statd). When a new value is set, the oldest value gets silently overwritten. Lost values are skipped when getting values from the item.
