+/*
+ * This package provides several types of thread operation debugging:
+ *
+ * - Check the results of operations on threads, mutexes, condition
+ * variables and read/write locks. Also check some thread pool
+ * operations, but not those for which failure can happen in normal
+ * slapd operation.
+ *
+ * - Wrap those types except threads and pools in structs with state
+ * information, and check that on all operations:
+ *
+ * + Check that the resources are initialized and are only used at
+ * their original address (i.e. not realloced or copied).
+ *
+ * + Check the owner (thread ID) on mutex operations.
+ *
+ * + Optionally allocate a reference to a byte of dummy memory.
+ * This lets malloc debuggers see some incorrect use as memory
+ * leaks, access to freed memory, etc.
+ *
+ * - Print an error message and by default abort() upon errors.
+ *
+ * - Print a count of leaked thread resources after cleanup.
+ *
+ * Compile-time (./configure) setup: Macros defined in CPPFLAGS.
+ *
+ * LDAP_THREAD_DEBUG or LDAP_THREAD_DEBUG=2
+ * Enables debugging, but value & 2 turns off type wrapping.
+ *
+ * LDAP_UINTPTR_T=integer type to hold pointers, preferably unsigned.
+ * Used by dummy memory option "scramble". Default = unsigned long.
+ *
+ * LDAP_DEBUG_THREAD_NONE = initializer for a "no thread" thread ID.
+ *
+ * In addition, you may need to set up an implementation-specific way
+ * to enable whatever error checking your thread library provides.
+ * Currently only implemented for Posix threads (pthreads), where
+ * you may need to define LDAP_INT_THREAD_MUTEXATTR. The default
+ * is PTHREAD_MUTEX_ERRORCHECK, or PTHREAD_MUTEX_ERRORCHECK_NP for
+ * Linux threads. See pthread_mutexattr_settype(3).
+ *
+ * Run-time configuration:
+ *
+ * Memory debugging tools:
+ * Tools that report uninitialized memory accesses should disable
+ * such warnings about the function debug_already_initialized().
+ * Alternatively, include "noreinit" (below) in $LDAP_THREAD_DEBUG.
+ *
+ * Environment variable $LDAP_THREAD_DEBUG:
+ * The variable may contain a comma- or space-separated option list.
+ * Options:
+ * off - Disable this package. (It still slows things down).
+ * tracethreads - Report create/join/exit/kill of threads.
+ * noabort - Do not abort() on errors.
+ * noerror - Do not report errors. Implies noabort.
+ * nocount - Do not report counts of unreleased resources.
+ * nosync - Disable tests that use synchronization and thus
+ * clearly affect thread scheduling:
+ * Implies nocount, and cancels threadID if that is set.
+ * Note that if you turn on tracethreads or malloc
+ * debugging, these also use library calls which may
+ * affect thread scheduling (fprintf and malloc).
+ * The following options do not apply if type wrapping is disabled:
+ * nomem - Do not check memory operations.
+ * Implies noreinit,noalloc.
+ * noreinit - Do not catch reinitialization of existing resources.
+ * (That test accesses uninitialized memory).
+ * threadID - Trace thread IDs. Currently mostly useless.
+ * Malloc debugging -- allocate dummy memory for initialized
+ * resources, so malloc debuggers will report them as memory leaks:
+ * noalloc - Default. Do not allocate dummy memory.
+ * alloc - Store a pointer to dummy memory. However, leak
+ * detectors might not catch unreleased resources in
+ * global variables.
+ * scramble - Store bitwise complement of dummy memory pointer.
+ * That never escapes memory leak detectors -
+ * but detection while the program is running will
+ * report active resources as leaks. Do not
+ * use this if a garbage collector is in use:-)
+ * adjptr - Point to end of dummy memory.
+ * Purify reports these as "potential leaks" (PLK).
+ * I have not checked other malloc debuggers.
