* struct datum
*
* Instances of struct datum are used to store information on entries
* that may be loaded into the cache. The individual fields are
* discussed below:
*
* header: Instance of H5C_cache_entry_t used by the for its data.
* This field is only used on the file processes, not on the
* server process.
*
* This field MUST be the first entry in this structure.
*
* base_addr: Base address of the entry.
*
* len: Length of the entry.
*
* local_len: Length of the entry according to the cache. This
* value must be positive, and may not be larger than len.
*
* The field exists to allow us change the sizes of entries
* in the cache without upsetting the server. This value
* is only used locally, and is never sent to the server.
*
* ver: Version number of the entry. This number is initialize
* to zero, and incremented each time the entry is modified.
*
* dirty: Boolean flag indicating whether the entry is dirty.
*
* For current purposes, an entry is clean until it is
* modified, and dirty until written to the server (cache
* on process 0) or until it is marked clean (all other
* caches).
*
* valid: Boolean flag indicating whether the entry contains
* valid data. Attempts to read an entry whose valid
* flag is not set should trigger an error.
*
* locked: Boolean flag that is set to true iff the entry is in
* the cache and locked.
*
* global_pinned: Boolean flag that is set to true iff the entry has
* been pinned collectively in all caches. Since writes must
* be collective across all processes, only entries pinned
* in this fashion may be marked dirty.
*
* local_pinned: Boolean flag that is set to true iff the entry
* has been pinned in the local cache, but probably not all
* caches. Such pins will typically not be consistant across
* processes, and thus cannot be marked as dirty unless they
* happen to overlap some collective operation.
*
* cleared: Boolean flag that is set to true whenever the entry is
* dirty, and is cleared via a call to clear_datum().
*
* flushed: Boolean flag that is set to true whenever the entry is
* dirty, and is flushed via a call to flush_datum().
*
* reads: Integer field used to maintain a count of the number of
* times this entry has been read from the server since
* the last time the read and write counts were reset.
*
* writes: Integer field used to maintain a count of the number of
* times this entry has been written to the server since
* the last time the read and write counts were reset.
*
* index: Index of this instance of datum in the data_index[] array
* discussed below.

* The following two #defines are used to control code that is in turn used
* to force "POSIX" semantics on the server process used to simulate metadata
* reads and writes. Without some such mechanism, the test code contains
* race conditions that will frequently cause spurious failures.
*
* When set to TRUE, DO_WRITE_REQ_ACK forces the server to send an ack after
* each write request, and the client to wait until the ack is received
* before proceeding. This was my first solution to the problem, and at
* first glance, it would seem to have a lot of unnecessary overhead.
*
* In an attempt to reduce the overhead, I implemented a second solution
* in which no acks are sent after writes. Instead, the metadata cache is
* provided with a callback function to call after each sequence of writes.
* This callback simply causes the client to send the server process a
* "sync" message and and await an ack in reply.
*
* Strangely, at least on Phoenix, the first solution runs faster by a
* rather large margin. However, I can imagine this changing with
* different OS's and MPI implementatins.
*
* Thus I have left code supporting the second solution in place.
*
* Note that while one of these two #defines must be set to TRUE, there
* should never be any need to set both of them to TRUE (although the
* tests will still function with this setting).

* Function: trace_file_check()

* Purpose: A basic test of the trace file capability. In essence,

* and then verify that the expected output was generated.
*
* Note that the trace file is currently implemented at the
* H5AC level, so all calls have to go through H5AC. Thus it
* is more convenient to test trace file capabilities in the
* parallel cache test which works at the H5AC level, instead
* of in the serial test code which does everything at the
* H5C level.
*
* The function must test trace file output in the following
* functions:
*
* - H5AC_flush()
* - H5AC_insert_entry()
* - H5AC_mark_entry_dirty()
* - H5AC_move_entry()
* - H5AC_pin_protected_entry()
* - H5AC_protect()

* - H5AC_unprotect()
* - H5AC_set_cache_auto_resize_config()
* - H5AC_expunge_entry()
* - H5AC_resize_entry()
