2015-07-02res_timing: Don't close FD 0 when out of open files.Walter Doekes
This fixes so a failure to get a timer file descriptor does not cascade to closing FD 0. On error, both res_timing_kqueue and res_timing_timerfd would call the destructor before setting the file handle. The file handle had been initialized to 0, causing FD 0 to be closed. This in turn, resulted in floods of "CLI>" messages and an unusable terminal. ASTERISK-19277 #close Reported by: Barry Chern For the master branch, this was already fixed. This patch only ensures that we do not attempt to close a negative file descriptor. Change-Id: I147d7e33726c6e5a2751928d56561494f5800350

2014-02-07timing: Improve performance for most timing implementations.Joshua Colp
This change allows timing implementation data to be stored directly on the timer itself thus removing the requirement for many implementations to do a container lookup for the same information. This means that API calls into timing implementations can directly access the information they need instead of having to find it.

2012-11-05Refactor ast_timer_ack to return an error and handle the error in timer usersMatthew Jordan
Currently, if an acknowledgement of a timer fails Asterisk will not realize that a serious error occurred and will continue attempting to use the timer's file descriptor. This can lead to situations where errors stream to the CLI/log file. This consumes significant resources, masks the actual problem that occurred (whatever caused the timer to fail in the first place), and can leave channels in odd states. This patch propagates the errors in the timing resource modules up through the timer core, and makes users of these timers handle acknowledgement failures. It also adds some defensive coding around the use of timers to prevent using bad file descriptors in off nominal code paths. Note that the patch created by the issue reporter was modified slightly for this commit and backported to 1.8, as it was originally written for Asterisk 10.

2011-12-27Fix timing source dependency issues with MOHMatthew Jordan
Prior to this patch, res_musiconhold existed at the same module priority level as the timing sources that it depends on. This would cause a problem when music on hold was reloaded, as the timing source could be changed after res_musiconhold was processed. This patch adds a new module priority level, AST_MODPRI_TIMING, that the various timing modules are now loaded at. This now occurs before loading other resource modules, such that the timing source is guaranteed to be set prior to resolving the timing source dependencies.

To fix this issue the alert pipe will now be used when the timerfd module is in use. There appeared to be a race that was not solved by adding locking in the timerfd module, but needed to be there anyway. The race was between the timer being put in non-continuous mode in ast_read on the channel thread and the IAX frame scheduler queuing a frame which would enable continuous mode before the non-continuous mode event was read. This race for now is simply avoided. (closes issue #18110) Reported by: tpanton Tested by: tpanton I put tested by tpanton because it was tested on his hardware.

2009-06-09module load priorityDavid Vossel
This patch adds the option to give a module a load priority. The value represents the order in which a module's load() function is initialized. The lower the value, the higher the priority. The value is only checked if the AST_MODFLAG_LOAD_ORDER flag is set. If the AST_MODFLAG_LOAD_ORDER flag is not set, the value will never be read and the module will be given the lowest possible priority on load. Since some modules are reliant on a timing interface, the timing modules have been given a high load priorty.

2009-01-16Fix a logic error that occur when using the timerfd interfaceMark Michelson
This sequence of events posed a problem timerfd_timer_open timerfd_timer_enable_continuous timerfd_timer_set_rate timerfd_timer_disable_continuous The reason was that the timing module was written under the assumption that timerfd_timer_set_rate would not be called between enabling and disabling continuous mode. What happened in this situation was that timerfd_timer_enable_continuous saved off our previously set timer (in this situation a 0 timer, meaning it never runs out). Then timerfd_timer_disable_continuous would restore this 0 timer, even though it logically should set the timer to be whatever was set in timerfd_timer_set_rate. Now the behavior in timerfd_timer_set_rate is to overwrite the saved timer that may or may not have been set in timerfd_timer_enable_continuous. Even if timerfd_timer_enable_continuous has not been previously called, this will not harm the operation. Thanks to Terry Wilson for discovering the problem and giving me a really great debug capture that pointed out the problem clearly git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@168898 65c4cc65-6c06-0410-ace0-fbb531ad65f3

2008-11-19Merge the changes from the res_timing_timerfd branch.Mark Michelson
This provides a new timing interface. In order to use it, you must be running a Linux with a kernel version of 2.6.25 or newer and glibc 2.8 or newer. This timing interface is a good alternative if a timing source is necessary (e.g. for IAX trunking) but DAHDI is otherwise unnecessary for the system. For now, this commit contains the actual work done in the res_timing_timerfd branch. There are no notices in the README or CHANGES files yet, but they will be added in my next commit. The timing API of Asterisk also needs to have a bit of work done with regards to choosing which timing interface to use. This commit makes the choice a build-time decision, by only allowing one of the timer interfaces to be chosen in menuselect. It would be preferable if the choice could be made at run-time, however. The preferred timing interface could be loaded and tested, and if it does not work, choice number two may be used instead. That sort of thing. That is beyond the scope of work in this branch though. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@157820 65c4cc65-6c06-0410-ace0-fbb531ad65f3
