For this to fully work, the library had to be split so that we can avoid the irmd calling these functions (the IRMd has to create the shm structures on which these calls depend). The library is split in 3 parts: libouroboros-dev, libouroboros-irm and libouroboros-common. The latter is linked to the other two so that including libouroboros-dev or libouroboros-irm will also link libouroboros-common. 2017-10-11T13:28:43+00:00 dimitri staessens dimitri.staessens@ugent.be 2017-10-11T13:28:43+00:00 urn:sha1:a483bc8597e5c19e796dc55c0587f1a045bc7281 Closing the file descriptor after a while(true) loop led to clang compiler errors. This is fixed by adding a cleanup handler. 2017-10-07T08:11:00+00:00 dimitri staessens dimitri.staessens@ugent.be 2017-10-07T08:06:22+00:00 urn:sha1:15ccd8ac0d1a7bfab2db3929200f3926c1e05db2 This adds a cleanup handler to ensure the lock is released in the event that the thread is cancelled during a write. An alternative solution could be to make the flow write in a non-blocking way (only the blocking write contains an execution path that has a cancellation point). Fixes #55 2017-09-30T15:58:18+00:00 dimitri staessens dimitri.staessens@ugent.be 2017-09-30T15:58:18+00:00 urn:sha1:9405ad97e20686f74c06bcbac9523a8b4f10272e This makes the threadpool use pthread_cancel instead of setting an exit flag that threadpool managed threads check periodically. This drastically reduces CPU consumption in the irmd when running a lot of applications. It requires cancellation handlers in the ipcp and irmd to be implemented to ensure safe cancellation during operation and shutdown. 2017-09-29T13:12:36+00:00 Sander Vrijders sander.vrijders@ugent.be 2017-09-27T15:24:59+00:00 urn:sha1:39c7f82f4714f8515860d1c0e2726bff29e22944 This will let the link state policy react to flow up and down events by notifying the PFFs of the routing instances of this event so they can take an appropriate action. 2017-09-29T13:12:36+00:00 Sander Vrijders sander.vrijders@ugent.be 2017-09-27T13:33:39+00:00 urn:sha1:e3dba5812b1422a79e6e77ce9f923bade5a480e4 This adds the Loop-Free Alternates (LFA) policy. In case a link goes down a LFA may be selected to route the SDUs on without causing loops instead of the main hop that just went down. 2017-09-26T13:27:14+00:00 Sander Vrijders sander.vrijders@ugent.be 2017-09-26T13:27:14+00:00 urn:sha1:ddba836eb79ace3bd80ea6af69801f402cbffd20 Be routing 2017-09-26T13:27:19+00:00 Sander Vrijders sander.vrijders@ugent.be 2017-09-25T15:36:18+00:00 urn:sha1:5d01c511fc1c31fdeee6bb515be0ca300854ba21 This adds a refcount to the graph edges so that it is only included in the calculation if both sides announced it. 2017-09-26T09:03:34+00:00 Sander Vrijders sander.vrijders@ugent.be 2017-09-26T09:03:34+00:00 urn:sha1:9c8d57ce793fff0b2c42c4cfc0d8ab97d554e1d8 ipcpd: normal: Set clock to realtime clock 2017-09-26T09:02:03+00:00 Sander Vrijders sander.vrijders@ugent.be 2017-09-26T09:02:03+00:00 urn:sha1:90900d36b7a380fee19b2171f4e49eed1eb35e8d A pthread_cond_wait was using the pthread_cond_clock and thereby timing out constantly, consuming 100% CPU. This changes it to use the realtime clock.
