tools: Use non-blocking read in servers

2018-03-16T11:05:40+00:00

The oping and ocbr servers were using non-blocking read/writes. This caused writes to fail on high-performance tests if the buffer got full, instead of waiting for a slot in the buffer. The write failure caused the server to quit. This fixes the tools by setting the I/O to blocking write and non-blocking read. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Use PTHREAD_COND_CLOCK for blocking reads

2018-03-10T12:01:23+00:00

The rbuff uses the PTHREAD_COND_CLOCK for its condition variables, but the flow_read was passing a time it got from the CLOCK_REALTIME_COARSE clock. This causes the blocking reads not to timeout correctly. The oping was updated to detect server timeouts and finish gracefully. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

tools: Don't cancel reader thread in oping

2018-03-05T09:43:30+00:00

The reader thread was cancelled as soon as the writer was finished, which resulted in missed responses and misreported packet loss. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Allow out-of-tree build of tools

2018-02-14T16:58:51+00:00

This removes the dependencies for the tools on some ouroboros internal headers (endian.h and time_utils.h) so they can be built out-of-tree. The echo-app tool has been renamed oecho and the cbr tool has been renamed ocbr. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Use GNUInstallDirs instead of hardcoded values

2018-02-06T17:27:38+00:00

This changes the build to use GNUInstallDirs instead of hardcoded values. Package maintainers can then override these defaults by passing the correct value to cmake on the command line. Signed-off-by: Sander Vrijders

tools: Fix SEGV in oping client

2017-11-22T08:57:36+00:00

The oping client tried to cancel non-created pthreads if it was killed during flow allocation, which caused a SEGV. The threads are now stopped using a variable. Fixes bug #2. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

tools: Send time in oping packets

2017-11-19T09:32:22+00:00

The oping tool now stores the time it sent the packet inside the SDU, simplifying the implementation. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

tools: Change license to 3 clause BSD

2017-10-24T18:11:05+00:00

A more permissive license is needed on the tools since they serve as example code for programs built on top of the ouroboros-dev and ouroboros-irm libraries. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Deprecate ouroboros_init and ourboros_fini

2017-10-14T11:19:10+00:00

This commit deprecates ouroboros_init and ouroboros_fini and adds them as a constructor or destructor, causing these function to be run automatically when a program that links to the library calls and exits main(). 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.
