2020-04-19timer.c: make timers thread safeEric1-3/+3
This is implicitly used by the libosmocore select abstraction, which might be used in multiple threads at the same time. Change-Id: I5a3802c94af6ff0315f1553f20870342d51ce726
2019-03-27Doxygen: fix documentation of osmo_timer_setup()Vadim Yanitskiy1-2/+2
This change fixes the following Doxygen warnings: timer.c:69: warning: argument 'callback' of command @param is not found in the argument list of osmo_timer_setup(struct osmo_timer_list *timer, void(*cb)(void *data), void *data) timer.c:69: warning: argument 'pointer' of command @param is not found in the argument list of osmo_timer_setup(struct osmo_timer_list *timer, void(*cb)(void *data), void *data) core/timer.h:70: warning: The following parameters of osmo_timer_setup(struct osmo_timer_list *timer, void(*cb)(void *data), void *data) are not documented: parameter 'cb' parameter 'data' Change-Id: If5668f40a7bfde2f4f22329a071c8c6eff23b99e

2017-06-23doxygen: unify use of \file across the boardNeels Hofmeyr1-3/+2
Considering the various styles and implications found in the sources, edit scores of files to follow the same API doc guidelines around the doxygen grouping and the \file tag. Many files now show a short description in the generated API doc that was so far only available as C comment. The guidelines and reasoning behind it is documented at https://osmocom.org/projects/cellular-infrastructure/wiki/Guidelines_for_API_documentation In some instances, remove file comments and add to the corresponding group instead, to be shared among several files (e.g. bitvec).

2017-06-23doxygen: enable AUTOBRIEF, drop \briefNeels Hofmeyr1-11/+11
Especially for short descriptions, it is annoying to have to type \brief for every single API doc. Drop all \brief and enable the AUTOBRIEF feature of doxygen, which always takes the first sentence of an API doc as the brief description. Change-Id: I11a8a821b065a128108641a2a63fb5a2b1916e87
2017-06-12update/extend doxygen documentationHarald Welte1-2/+2
It's a pity that even with this patch we still are fare away from having the whole API documented. However, at least we have a more solid foundation. Updates not only extend the documentation, but also make sure it is rendered properly in the doxygen HTML. Change-Id: I1344bd1a6869fb00de7c1899a8db93bba9bafce3

2017-05-09timer: add osmo_timer_setup()Pablo Neira Ayuso1-0/+12
Add a new function timer function to set up the timer, similar to what we have in the Linux kernel. This patch also converts existing opencoded timer setup in the libosmocore tree as initial client of this new function. This patch implicitly removes function callback passed by reference that defeat compile time type validation. Compile-tested only, but I ran make check that reports success when testing timer infrastructure. Change-Id: I2fa49972ecaab3748b25168b26d92034e9145666
2016-11-28timer: only call the callback if not NULLAlexander Couzens1-1/+2
Fix a crash in osmo-sgsn. Change-Id: I04d58d9580708cc0f6d0f4aa17d3e9f2c6235c8e
2016-09-22add osmo_gettimeofday as a shim around gettimeofdayNeels Hofmeyr1-4/+4
This allows feeding a custom time for unit tests by overriding osmo_gettimeofday. Change-Id: Ic7a81a6eb51f27fe452962b91f2eae2070d87089
2016-05-05Update doxygen annotations in libosmocoreHarald Welte1-0/+2
This adds and improves doxygen API descriptions all over libosmocore, reducing the 'white spots' that don't have any documentation.
2015-08-21timer: Fix compiler warning about timevalHolger Hans Peter Freyther1-3/+4
timer.c:27:23: warning: tentative definition of variable with internal linkage has incomplete non-array type 'struct timeval' [-Wtentative-definition-incomplete-type] static struct timeval nearest; ^ timer.c:27:15: note: forward declaration of 'struct timeval' static struct timeval nearest;
2014-05-23timer: Use the now parameter when it is not NULLHolger Hans Peter Freyther1-3/+3
The code would have used an uninitialized current_time in case "now" was not NULL. As now is const and timersub expects a non const parameter I decided to copy now into current_time. Fixes: CID #1040661
2013-02-15misc: Doxygen tweaks: fixed some typos and minor errorsKaterina Barone-Adesi1-1/+1
Doxygen generates quite a lot of warnings on libosmocore. Some of them are obvious typos - this patch aims to fix such low-hanging fruit.

2011-11-13timer: Better fix to the timer re-scheduling situationPablo Neira Ayuso1-6/+3
As it turns out, the previous fix didn't cover the case of a timer X being re-scheduled inside a timer call back expiring at the same time as the previous X instance. Written-by: Pablo Neira Ayuso <pablo@gnumonks.org> Signed-off-by: Sylvain Munaut <tnt@246tNt.com>

2011-10-17timer: add scalable RB-tree based timer infrastructurePablo Neira Ayuso1-81/+95
This patch adds RB-tree based timers which scales better than the previous list-based implementation. It does not require any API changes. It breaks ABI because the osmo_timer_list structure has changed though (to avoid this in the future, we can put internal data in some private structure). The following table summarizes the worst-case computational complexity of this new implementation versus the previous one: rb-tree list-based ------- ---------- calculate next timer to expire O(1) O(n) insertion of new timer O(log n) O(n) deletion of timer O(log n) O(1) timer-fired scheduler O(log n) O(3n) The most repeated cases are: * the calculation of the next timer to expire, that happens in every loop of our select function. * the timer-fired scheduler execution. This new implementation only loses in the deletion of timer scenario, this happens because we may need to rebalance the tree after the removal. So I think there is some real gain if we have some situation in which we have to handle lots of timers.
