* libglusterfs: Move devel headers under glusterfs directoryShyamsundarR2018-12-052-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | libglusterfs devel package headers are referenced in code using include semantics for a program, this while it works can be better especially when dealing with out of tree xlator builds or in general out of tree devel package usage. Towards this, the following changes are done, - moved all devel headers under a glusterfs directory - Included these headers using system header notation <> in all code outside of libglusterfs - Included these headers using own program notation "" within libglusterfs This change although big, is just moving around the headers and making it correct when including these headers from other sources. This helps us correctly include libglusterfs includes without namespace conflicts.

* glusterfs: Use gcc builtin ATOMIC operator to increase/decreate refcount.Mohit Agrawal2017-12-121-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: In glusterfs code base we call mutex_lock/unlock to take reference/dereference for a object.Sometime it could be reason for lock contention also. Solution: There is no need to use mutex to increase/decrease ref counter, instead of using mutex use gcc builtin ATOMIC operation. Test: I have not observed yet how much performance gain after apply this patch specific to glusterfs but i have tested same with below small program(mutex and atomic both) and get good difference. static int numOuterLoops; static void * threadFunc(void *arg) { int j; for (j = 0; j < numOuterLoops; j++) { __atomic_add_fetch (&glob, 1,__ATOMIC_ACQ_REL); } return NULL; } int main(int argc, char *argv[]) { int opt, s, j; int numThreads; pthread_t *thread; int verbose; int64_t n = 0; if (argc < 2 ) { printf(" Please provide 2 args Num of threads && Outer Loop\n"); exit (-1); } numThreads = atoi(argv[1]); numOuterLoops = atoi (argv[2]); if (1) { printf("\tthreads: %d; outer loops: %d;\n", numThreads, numOuterLoops); } thread = calloc(numThreads, sizeof(pthread_t)); if (thread == NULL) { printf ("calloc error so exit\n"); exit (-1); } __atomic_store (&glob, &n, __ATOMIC_RELEASE); for (j = 0; j < numThreads; j++) { s = pthread_create(&thread[j], NULL, threadFunc, NULL); if (s != 0) { printf ("pthread_create failed so exit\n"); exit (-1); } } for (j = 0; j < numThreads; j++) { s = pthread_join(thread[j], NULL); if (s != 0) { printf ("pthread_join failed so exit\n"); exit (-1); } } printf("glob value is %ld\n",__atomic_load_n (&glob,__ATOMIC_RELAXED)); exit(0); } time ./thr_count 800 800000 threads: 800; outer loops: 800000; glob value is 640000000 real 1m10.288s user 0m57.269s sys 3m31.565s time ./thr_count_atomic 800 800000 threads: 800; outer loops: 800000; glob value is 640000000 real 0m20.313s user 1m20.558s sys 0m0.028 Change-Id: Ie5030a52ea264875e002e108dd4b207b15ab7cc7 Signed-off-by: Mohit Agrawal <moagrawa@redhat.com>
* build: do not #include "config.h" in each fileNiels de Vos2015-05-291-5/+0
| | | | | | | | | | | | | | | | | | Instead of including config.h in each file, and have the additional config.h included from the compiler commandline (-include option). When a .c file tests for a certain #define, and config.h was not included, incorrect assumtions were made. With this change, it can not happen again.

* core: use reference counting for mem_acct structuresJeff Darcy2015-05-091-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When freeing memory, our memory-accounting code expects to be able to dereference from the (previously) allocated block to its owning translator. However, as we have already found once in option validation and twice in logging, that translator might itself have been freed and the dereference attempt causes on of our daemons to crash with SIGSEGV. This patch attempts to fix that as follows: * We no longer embed a struct mem_acct directly in a struct xlator, but instead allocate it separately. * Allocated memory blocks now contain a pointer to the mem_acct instead of the xlator. * The mem_acct structure contains a reference count, manipulated in both the normal and translator allocate/free code using atomic increments and decrements. * Because it's now a separate structure, we can defer freeing the mem_acct until its reference count reaches zero (either way). * Some unit tests were disabled, because they embedded their own copies of the implementation for what they were supposedly testing. Life's too short to spend time fixing tests that seem designed to impede progress by requiring a certain implementation as well as behavior.

* Avoid conflict between contrib/uuid and system uuidEmmanuel Dreyfus2015-04-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glusterfs relies on Linux uuid implementation, which API is incompatible with most other systems's uuid. As a result, libglusterfs has to embed contrib/uuid, which is the Linux implementation, on non Linux systems. This implementation is incompatible with systtem's built in, but the symbols have the same names. Usually this is not a problem because when we link with -lglusterfs, libc's symbols are trumped. However there is a problem when a program not linked with -lglusterfs will dlopen() glusterfs component. In such a case, libc's uuid implementation is already loaded in the calling program, and it will be used instead of libglusterfs's implementation, causing crashes. A possible workaround is to use pre-load libglusterfs in the calling program (using LD_PRELOAD on NetBSD for instance), but such a mechanism is not portable, nor is it flexible. A much better approach is to rename libglusterfs's uuid_* functions to gf_uuid_* to avoid any possible conflict. This is what this change attempts.

* testing: Switch to cmocka the successor of cmockery2Niels de Vos2015-03-051-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | This uses https://cmocka.org/ as the unit testing framework. With this change, unit testing is made optional as well. We assume there is no cmocka available while building. cmocka will be enabled by default later on. For now, to build with cmocka run: $ ./configure --enable-cmocka This change is based on the work of Andreas (replacing cmockery2 with cmocka) and Kaleb (make cmockery2 an optional build dependency). The only modifications I made, are additional #defines in unittest.h for making sure the unit tests function as expected.
