4 dayslogging: Change LLAPD category color to purple-like oneHEADmasterPau Espin Pedrol1-1/+1
Previous dark shiny blue one is really difficult to read on the terminal. Let's change it for some purpleish color which is far easier to read. Change-Id: Ia5c0860dd8d756bb24eb8972f94590bfba5bc865

2021-10-04utils: remove misleading comments for osmo_hexdump[_nospc]_c()Vadim Yanitskiy1-6/+0

2021-10-04revisit some calls of strtol(), stroul(), strtoull()Neels Hofmeyr7-73/+31
Replace some with atoi(), where the VTY has already validated correct range of the argument. Replace others with the new osmo_str_to_int() or osmo_str_to_int64() functions, possibly covering more detection of invalid number strings. Leave those strtol() callers that depend on endptr to provide the next string token. Related: SYS#5542 Change-Id: I0ebb06e751c28f7d1cdf328de29cd227a2449391
2021-10-01fix rsl_chan_nr_str_{buf,c}(): enlarge the buffer sizeVadim Yanitskiy1-3/+3
20 bytes is not enough for some VAMOS specific channel number values, so the resulting string representation gets truncated by snprintf(): expected: "VAMOS TCH/H(0) on TS4\0" actual: "VAMOS TCH/H(0) on T\0" Let's enlarge the buffers to 32 bytes. Change-Id: I68d839f4ab742cf56de34e7e22572a1163aec2da

2021-09-30refactor stat_item: report only changed valuesNeels Hofmeyr4-14/+9
Change the functionality of skipping unchanged values: instead of looking up whether new values have been set on a stat item, rather remember the last reported value and skip reporting identical values. stats_test.c shows that previously, a stat item reported a value of 10 again, even though the previous report had already sent a value of 10. That's just because the value 10 was explicitly set again, internally. From a perspective of preserving all data points, it could make sense to send consecutive identical values. But since we already collapse all data points per reporting period into a max, that is pointless. Related: SYS#5542 Change-Id: I8f4cf34dfed17e0879716fa2cbeee137c158978b
2021-09-30refactor stat_item: get rid of FIFO and "skipped" errorNeels Hofmeyr11-335/+371
Intead of attempting to store all distinct values of a reporting period, just store min, max, last as well as a sum and N of each reporting period. This gets rid of error messages like DLSTATS ERROR stat_item.c:285 num_bts:oml_connected: 44 stats values skipped while at the same time more accurately reporting the max value for each reporting period. (So far stats_item only reports the max value; keep that part unchanged, as shown in stats_test.c.) With the other so far unused values (min, sum), we are ready to also report the minimum value as well as an average value per reporting period in the future, if/when our stats reporter allows for it. Store the complete record of the previous reporting period. So far we only compare the 'max' value, but like this we are ready to also see changes in min, last and average value between reporting periods. This patch breaks API by removing: - struct members osmo_stats_item.stats_next_id, .last_offs and .values[] - struct osmo_stats_item_value - osmo_stat_item_get_next() - osmo_stat_item_discard() - osmo_stat_item_discard_all() and by making struct osmo_stats_item opaque. In libosmocore, we do have a policy of never breaking API. But since the above should never be accessed by users of the osmo_stats_item API -- or if they are, would no longer yield useful results, we decided to make an exception in this case. The alternative would be to introduce a new osmo_stats_item2 API and maintaining an unused legacy osmo_stats_item forever, but we decided that the effort is not worth it. There are no known users of the removed items. Related: SYS#5542 Change-Id: I137992a5479fc39bbceb6c6c2af9c227bd33b39b

2021-09-20stats_test: assert counter and stat item val counts separatelyNeels Hofmeyr2-57/+51
Instead of just a send_count, keep one such count for the counter updates, and a separate one for the stat item updates. Print those numbers in the test output. An upcoming patch will tweak stat_item reporting so that only an actually changed value results in sending a new stat value. This patch allows illustrating that change clearly.

2021-09-14add osmo_stat_item_get_group_by_name_idxname()Neels Hofmeyr2-0/+21
Add "missing" API for looking up a stat_item_group by its index-name. A subsequent patch, which adds stat_items to the CTRL interface, will use this to look up stat item groups by object name. In stat item groups, there are group names, having a number of indexes denoting different objects. An object can have, besides the index, also a name that is equivalent to the index. Apologies for the weird function name, it's still the best one I could come up with: "group_by_name" refers to the group name, and "idxname" refers to the name that the object index is associated with. We already have osmo_stat_item_get_group_by_name_idx(). Other contestants for name of this new function were: - osmo_stat_item_get_group_by_name_name() because there is a "name" instead of "idx", but I find it confusing. - osmo_stat_item_get_group_by_name_idx_name() but I find that the last "name" should be closer to the "idx".

2021-09-12utils: add osmo_str_to_int() and osmo_str_to_int64()Neels Hofmeyr4-3/+413
Properly converting a string to an integer while validating against all possible errors is not trivial. It is a recurring theme in code review, and there are places in osmo code that do it wrong. End this by providing a simple API, if for nothing else then as an example of how to use strol() / strtoul() / strtoll() / strtoull() in an airtight way. A subsequent patch, adding stat items to the CTRL interface, uses this to properly validate indexes in CTRL variables and convert them to int.
