* 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.
