ouroboros/src/lib/shm_ap_rbuff.c, branch 0.2 Ouroboros main repository http://www.ouroboros.rocks/cgit/ouroboros/atom?h=0.2 2016-07-02T17:11:12+00:00 lib: robust locking in shared memory and crash recovery 2016-07-02T17:11:12+00:00 dimitri staessens dimitri.staessens@intec.ugent.be 2016-06-30T21:14:14+00:00 urn:sha1:79475a4742bc28e1737044f2300bcb601e6e10bf This PR enhances the shared memory providing recovery if a process crashes. It adds a SHM_DU_TIMEOUT_MICROS variable, setting an expiration time for SDU's when shared memory is full. If an application doesn't read a blocking SDU within this time, the shared memory will be cleansed of all SDU's for this application and the application's rbuff will be cleared. Some refactoring of the API's. Fixed wrong pthread checks in IRMd. Fixes #13 Fixes #14 lib, irmd, ipcpd: Change pid to api 2016-06-28T14:45:45+00:00 Sander Vrijders sander.vrijders@intec.ugent.be 2016-06-28T14:38:03+00:00 urn:sha1:99d19307fae8f1370f52a62aee88fded624ad464 Changes the variable name as well to API instead of PID. build: Change install directories and set correct permissions 2016-06-20T18:57:25+00:00 Sander Vrijders sander.vrijders@intec.ugent.be 2016-06-20T18:57:25+00:00 urn:sha1:16323dcc9df15020e368d4324cf1c1d9dceac805 This sets the correct install directories for all the binaries, library and header files. It also sets the right permissions on the sockets and shared memory so that regular users can also use the ouroboros library. Root privileges are required to run the irmd.
