* doxygen: unify use of \file across the boardNeels Hofmeyr2017-06-231-5/+3
| | | | | | | | | | | | | | | | | 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: various fixes in core/timer.hNeels Hofmeyr2017-06-231-19/+16
| | | | | | | | | | | | Move a longish comment to the timer group so that it appears in the API doc. Un-doxygen some floating comments that were associated with unrelated code items ('/**' --> '/*'). Add braces to some function names so that the API doc will render as reference links. Change-Id: I3ea5b88cbe9cb54702429158bf47e768e04e8fe7
* doxygen: enable AUTOBRIEF, drop \briefNeels Hofmeyr2017-06-231-8/+8
| | | | | | | | | | 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
* timer: add osmo_timer_setup()Pablo Neira Ayuso2017-05-091-0/+2
| | | | | | | | | | | | | | | 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
* add osmo_gettimeofday as a shim around gettimeofdayNeels Hofmeyr2016-09-221-0/+11
| | | | | | | This allows feeding a custom time for unit tests by overriding osmo_gettimeofday. Change-Id: Ic7a81a6eb51f27fe452962b91f2eae2070d87089

* timer: add scalable RB-tree based timer infrastructurePablo Neira Ayuso2011-10-171-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Ayuso2011-03-231-0/+72
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>
