Hi, all, Here's a silly fossil trick you'll certainly never need to do...
observe the creation of delta- vs baseline manifests in the repository by looking at historical checkin data... the larger (>10kb) checkins are baselines. The others are deltas generated from (normally) the next-oldest baseline. sqlite> select substr(b.uuid,0,12), datetime(ev.mtime), b.size from blob b join event ev on ev.objid=b.rid AND ev.type='ci' order by ev.mtime DESC limit 50 ; substr(b.uuid,0,12)|datetime(ev.mtime)|size e3e78d17862|2014-03-17 19:14:59|1824 811508a6020|2014-03-17 19:14:14|1765 8625a31eff7|2014-03-17 15:27:49|1756 e4bf163a5f0|2014-03-17 14:40:42|1412 47401e17639|2014-03-16 17:32:05|1420 adb83cc6102|2014-03-16 17:30:09|1297 c0b8ce3c1d7|2014-03-16 17:28:38|1290 2f280271d5d|2014-03-16 17:26:53|1219 be2b468e4e7|2014-03-16 17:08:57|1162 b96ea63caf4|2014-03-16 13:41:15|1147 752aad3eb7b|2014-03-16 13:03:37|1249 7943808461a|2014-03-16 11:25:47|1309 c8c97fd8fe1|2014-03-15 17:36:14|986 439762f2053|2014-03-15 17:28:13|282 9664c64ba37|2014-03-15 15:39:03|14270 <<-- baseline 3e6f247357b|2014-03-15 15:02:48|1688 f17950f7756|2014-03-15 15:02:30|1685 2cbcbf62a31|2014-03-15 15:01:43|1681 a92bffdddff|2014-03-15 13:35:58|1646 4be2703578b|2014-03-15 09:48:05|1590 a5bda1ae61d|2014-03-15 09:33:25|1624 668349fdb0c|2014-03-14 20:50:40|1608 968a993c60e|2014-03-14 14:53:40|1247 df8d4f2bb01|2014-03-14 14:51:20|866 c71f986d359|2014-03-14 14:25:30|828 853ec1f6503|2014-03-14 12:10:26|14065 <<-- baseline 5900ce9dee0|2014-03-14 12:01:23|1709 a75ca1c3231|2014-03-14 11:57:31|1706 c3660f5241c|2014-03-14 11:52:47|1975 7e8d0ecfe20|2014-03-14 11:10:05|1652 ab56d2d9a07|2014-03-14 11:04:43|1723 1dff0493d2d|2014-03-14 10:47:24|1541 286b8aea1a4|2014-03-14 00:07:25|1454 447f497409a|2014-03-13 23:48:38|1453 49961898ba4|2014-03-13 23:18:01|1406 ab6c9982c16|2014-03-13 21:50:54|1366 0096d28c969|2014-03-13 20:59:29|1370 9a07a781592|2014-03-13 20:53:34|1370 e3241eae556|2014-03-13 20:04:08|1290 4740bce980a|2014-03-13 19:42:13|1218 67c1885126c|2014-03-13 19:40:48|1215 2bba3a248f3|2014-03-13 18:20:34|1100 71f8421ed7d|2014-03-13 17:44:26|889 bc0e0001996|2014-03-13 15:39:09|974 2de81ae7b6a|2014-03-13 14:39:40|13764 <<-- baseline f994fec9c56|2014-03-13 12:00:02|1814 7e5ca27c8c9|2014-03-13 11:36:49|1648 7e759995ce1|2014-03-13 11:06:35|1553 375f435549d|2014-03-13 09:42:25|1254 c10bc4977a5|2014-03-13 09:41:33|1196 fossil uses an algorithm (which libfossil steals) to determine whether a given delta manifest is "too big to be worth the effort," and when it comes across that case it generates a baseline manifest instead. Thus every so often a new baseline appears. This same query on the core Fossil repo looks very different because it has no delta manifests - each checkin is currently about 44kb (uncompressed). So why is this all interesting data? Because i'm touching those particular bits in libfossil tonight and like to see that they're working :). Outside of that context, it's probably not all that interesting. -- ----- stephan beal http://wanderinghorse.net/home/stephan/ http://gplus.to/sgbeal "Freedom is sloppy.
