- * Revision 1.29 1995-11-21 15:01:14 adam
+ * Revision 1.44 1995-12-12 16:00:54 adam
+ * System call sync(2) used after update/commit.
+ * Locking (based on fcntl) uses F_EXLCK and F_SHLCK instead of F_WRLCK
+ * and F_RDLCK.
+ *
+ * Revision 1.43 1995/12/11 09:12:46 adam
+ * The rec_get function returns NULL if record doesn't exist - will
+ * happen in the server if the result set records have been deleted since
+ * the creation of the set (i.e. the search).
+ * The server saves a result temporarily if it is 'volatile', i.e. the
+ * set is register dependent.
+ *
+ * Revision 1.42 1995/12/07 17:38:46 adam
+ * Work locking mechanisms for concurrent updates/commit.
+ *
+ * Revision 1.41 1995/12/06 16:06:42 adam
+ * Better diagnostics. Work on 'real' dictionary deletion.
+ *
+ * Revision 1.40 1995/12/05 16:57:40 adam
+ * More work on regular patterns.
+ *
+ * Revision 1.39 1995/12/05 13:20:18 adam
+ * Bug fix: file_read sometimes returned early EOF.
+ *
+ * Revision 1.38 1995/12/04 17:59:21 adam
+ * More work on regular expression conversion.
+ *
+ * Revision 1.37 1995/12/04 14:22:27 adam
+ * Extra arg to recType_byName.
+ * Started work on new regular expression parsed input to
+ * structured records.
+ *
+ * Revision 1.36 1995/11/30 08:34:29 adam
+ * Started work on commit facility.
+ * Changed a few malloc/free to xmalloc/xfree.
+ *
+ * Revision 1.35 1995/11/28 14:26:21 adam
+ * Bug fix: recordId with constant wasn't right.
+ * Bug fix: recordId dictionary entry wasn't deleted when needed.
+ *
+ * Revision 1.34 1995/11/28 09:09:38 adam
+ * Zebra config renamed.
+ * Use setting 'recordId' to identify record now.
+ * Bug fix in recindex.c: rec_release_blocks was invokeded even
+ * though the blocks were already released.
+ * File traversal properly deletes records when needed.
+ *
+ * Revision 1.33 1995/11/27 09:56:20 adam
+ * Record info elements better enumerated. Internal store of records.
+ *
+ * Revision 1.32 1995/11/25 10:24:05 adam
+ * More record fields - they are enumerated now.
+ * New options: flagStoreData flagStoreKey.
+ *
+ * Revision 1.31 1995/11/24 11:31:35 adam
+ * Commands add & del read filenames from stdin if source directory is
+ * empty.
+ * Match criteria supports 'constant' strings.
+ *
+ * Revision 1.30 1995/11/22 17:19:16 adam
+ * Record management uses the bfile system.
+ *
+ * Revision 1.29 1995/11/21 15:01:14 adam
* New general match criteria implemented.
* New feature: document groups.
