* Assume mutex locking cannot failGreg Hudson2013-05-141-14/+10
| | | | | | | | | | | | Locking and unlocking a non-recursive mutex is a simple memory operation and should not fail on any reasonable platform with correct usage. A pthread mutex can return EDEADLK on lock or EPERM on unlock, or EINVAL if the mutex is uninitialized, but all of these conditions would reflect serious bugs in the calling code. Change the k5_mutex_lock and k5_mutex_unlock wrappers to return void and adjust all call sites. Propagate this change through k5_cc_mutex_lock and k5_cc_mutex_unlock as well.

* Based on patch from lxs, with some changes:Ken Raeburn2008-08-271-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add several new gcc warning flags, used in the KfM build process. Put declarations before code. Fix a bunch of signed/unsigned type mixes, mostly by changing variable types to unsigned int. Fix constness in handling name of default ccache name. Make sure functions get declared with prototypes: krb5int_pthread_loaded krb5int_gmt_mktime krb5int_aes_encrypt krb5int_aes_decrypt gssint_mecherrmap_init gssint_mecherramp_get. Don't shadow global names: stat accept index open encrypt. Fix variable shadowing in LDAP ASN.1 support. Don't define unused krb5int_local_addresses. Don't export internal krb5_change_set_password. Fix error return indications from gssint_oid_to_mech. Create and use k5-gmt_mktime.h to provide one global declaration of krb5int_gmt_mktime, needed before we've generated krb5.h on some platforms. Not incorporated from initial patch: const changes in function signatures. ticket: 6096 status: open git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@20697 dc483132-0cff-0310-8789-dd5450dbe970

* hooks for recording statistics on locking behaviorKen Raeburn2004-12-061-10/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Finish the hooks (left disabled by default) for logging somewhere the recorded timing behavior relating to the use of locks in the krb5 code. Currently, "reporting" means writing to /dev/tty or stderr, and the data is the number of times a mutex is locked, file and line where it was created, min/avg/max/stddev wait times to acquire the lock and hold times, and stats are only written out for locks that were locked a certain minimum number of times and with a minimum average wait time. The criteria are all controlled in threads.c, and k5-thread.h just has the hooks for gathering data. So turning on/off the data gathering requires a full rebuild, but tweaking the reporting is mostly just a relinking pass. (May also require adding a dependence on the math library to the support library; for a static build that may impact a lot of makefiles.) * include/k5-thread.h [DEBUG_THREADS_STATS]: Include string.h and inttypes.h.
