* Fix/Update copyright notices; Add SPDX annotationHarald Welte2017-11-131-0/+2
| | | | | | | | Let's fix some erroneous/accidential references to wrong license, update copyright information where applicable and introduce a SPDX-License-Identifier to all files. Change-Id: I39af26c6aaaf5c926966391f6565fc5936be21af
* doxygen: unify use of \file across the boardNeels Hofmeyr2017-06-231-3/+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).

* doxygen: enable AUTOBRIEF, drop \briefNeels Hofmeyr2017-06-231-11/+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
* update/extend doxygen documentationHarald Welte2017-06-121-2/+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
* timer: use timerclear() rather than explicit tv_set = tv_usec = 0Harald Welte2017-05-151-2/+1

* timer: add osmo_timer_setup()Pablo Neira Ayuso2017-05-091-0/+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
* timer: only call the callback if not NULLAlexander Couzens2016-11-281-1/+2

* add osmo_gettimeofday as a shim around gettimeofdayNeels Hofmeyr2016-09-221-4/+4
| | | | | | | This allows feeding a custom time for unit tests by overriding osmo_gettimeofday. Change-Id: Ic7a81a6eb51f27fe452962b91f2eae2070d87089
* Update doxygen annotations in libosmocoreHarald Welte2016-05-051-0/+2
| | | | | This adds and improves doxygen API descriptions all over libosmocore, reducing the 'white spots' that don't have any documentation.
* timer: Fix compiler warning about timevalHolger Hans Peter Freyther2015-08-211-3/+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;
* timer: Use the now parameter when it is not NULLHolger Hans Peter Freyther2014-05-231-3/+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
* misc: Doxygen tweaks: fixed some typos and minor errorsKaterina Barone-Adesi2013-02-151-1/+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.

* timer: add scalable RB-tree based timer infrastructurePablo Neira Ayuso2011-10-171-81/+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.

* include: reorganize headers file to include/osmocom/[gsm|core]Pablo Neira Ayuso2011-03-231-1/+1
| | | | | | | | | | | | This patch moves all GSM-specific definitions to include/osmocom/gsm. Moreover, the headers in include/osmocore/ have been moved to include/osmocom/core. This has been proposed by Harald Welte and Sylvain Munaunt. Tested with `make distcheck'. Signed-off-by: Pablo Neira Ayuso <pablo@gnumonks.org>
