822015-11-05T13:35:23 <jonasschnelli> wumpus: also did shut down / power off the host (mac) and there where no issues with the database.
832015-11-05T13:35:58 *** qpm has joined #bitcoin-core-dev
842015-11-05T13:36:02 <wumpus> well I never managed to get an error in the middle of record with #6948, so at least it should be more rare now
852015-11-05T13:36:05 <jonasschnelli> Steps i did (maybe i did something wrong): my snapshot has a synced chain up to ~350000 form PR https://github.com/bitcoin/bitcoin/pull/6917
862015-11-05T13:36:27 <jonasschnelli> then i stopped bitcoin-qt and started bitcoin-qt from https://github.com/bitcoin/bitcoin/pull/6948
872015-11-05T13:36:36 <jonasschnelli> did a power off hard shutdown
882015-11-05T13:36:50 <jonasschnelli> restarted win8.1 ... restarted bitcoin-qt from 6948
892015-11-05T13:36:59 <jonasschnelli> -> resulted in "Corruption: error in middle of record"
902015-11-05T13:37:01 <wumpus> but if that doesn't fix it I don't know, I really don't know anymore
912015-11-05T13:37:44 <jonasschnelli> switch away from leveldb
922015-11-05T13:38:05 <wumpus> maybe FlushFileBuffers on windows doesn't really flush the buffers
932015-11-05T13:38:09 <wumpus> no, I don't want to hear that
942015-11-05T13:38:42 <jonasschnelli> I'll do the test again ... maybe i missclicked somewhere.
952015-11-05T13:38:44 <wumpus> well, unless, have you tried this with another database at all?
962015-11-05T13:39:15 <jonasschnelli> sqlite3 was to slow i heard... i'd though about trying it with the unstable sqlite4 branch
972015-11-05T13:39:19 <wumpus> it would be somewhat interesting to try this with jgarzik's sqlite patch. At least to have a measurement point.
982015-11-05T13:39:53 <jonasschnelli> jgarzik uses seqlite3 which is certenly much slower then leveldb... sqlite4 sounds promising... and unstable.
992015-11-05T13:40:20 <wumpus> for this experiment I don't care about slowness - I wonder if *anything * can handle this kind of corruption succesfully
1002015-11-05T13:40:59 <jonasschnelli> when i restore my snapshot based on a ~synced chain with #6917, bitcoin-core crashed,... but can be started again with 100% success. Can that be a problem? I assume no?

1072015-11-05T13:43:50 <jonasschnelli> Maybe you'd like to start with the Win8.1 VM... you need VMWare Fusion 8 (or higher)
1082015-11-05T13:44:06 <fanquake> I'd take copies of the ones your using to test #6948
1092015-11-05T13:44:11 <wumpus> I suppose what leveldb should do when it encounters corruption in the middle of a record (probably a run of 0000000 like debug.log) is to simply discard that batch and anything after it
1102015-11-05T13:44:26 <fanquake> I'm actually setup somewhere with a decent internet connection atm, so downloading won't be so hard.

1142015-11-05T13:45:15 <wumpus> be careful to actually test #6948 on top of master, it's currently rebased to a pre-#6917 branch so as-is it won't test the robust version
1152015-11-05T13:46:00 <jonasschnelli> Yes. I'm using https://bitcoin.jonasschnelli.ch/pulls/6948/... has 22e780737db57bcb18b3824eb8158e19a4775cb6 and fb9857bfd68c13b52e14bc28dd981bc12501806a

1412015-11-05T14:31:01 <jgarzik> jonasschnelli, RE databases and comparison... I should have a fast replacement ready in a few weeks, https://github.com/jgarzik/pgdb2
1422015-11-05T14:31:45 <jgarzik> jonasschnelli, sqlite is probably too slow for useful benchmarking
1432015-11-05T14:31:46 <jonasschnelli> jgarzik: hah. Let me check out the code...
1442015-11-05T14:32:28 <jonasschnelli> jgarzik: what about sqlite4? It's says on the architecture website ("It is very fast, faster than LevelDB...",)
1452015-11-05T14:33:12 <jonasschnelli> And riding on one of the best maintained database layers would be nice... but right,.. it might be the wrong type of database
1462015-11-05T14:33:37 <jgarzik> jonasschnelli, https://sqlite.org/src4/doc/trunk/www/design.wiki definitely looks like they are catching up to modern design
1472015-11-05T14:34:32 <jonasschnelli> I have also though about your "pgdb2"-like-approach, ... but it seems to be a hard way.
1482015-11-05T14:34:56 <jgarzik> "The default built-in storage engine is a log-structured merge database. It is very fast, faster than LevelDB, supports nested transactions, and stores all content in a single disk file. "
1492015-11-05T14:35:12 * jgarzik knows what log-structured is. What is a merge database, I wonder
1502015-11-05T14:36:25 <jonasschnelli> jgarzik: would it be complicated to modificate your sqlite3 branch to use sqlite4? (over a subtree or something similar because it's unstable and not available over dep.management?)
1512015-11-05T14:36:40 <jgarzik> jonasschnelli, Part of pgdb2 is building an underlying framework that can be used for ordered-map key/value, hash tree key/value, merkle db and more - a bit of a primitive kernel filesystem that provides transactions/COW to the upper layer, which defines the key/value structure. It's the same speed (or faster, really)
1522015-11-05T14:37:03 <jgarzik> jonasschnelli, sounds like using sqlite4 is simple - take my branch and add 'env' argument to each function call.
1532015-11-05T14:38:48 <jonasschnelli> jgarzik: do you have plans to work towards sqlite4 and report some benchmark numbers? Or should i give it a try?
1542015-11-05T14:39:16 <jonasschnelli> but i really like to find a solution to fix the current leveldb corruption issues...
1552015-11-05T14:39:45 <jonasschnelli> although, i don't care about windows enough,.... but i care about users complaining about the issue and stopping full nodes.
1562015-11-05T14:40:29 <jgarzik> jonasschnelli, feel free to give sqlite4 a try. I consider my sqlite branch at a [temporary?] pause / end state. I task switched over to BIP 1xx and pgdb2.
1572015-11-05T14:41:18 <jonasschnelli> Okay. pgdb2 looks nice btw!
1582015-11-05T14:41:54 <sipa> jgarzik: merge database... there are several files that can refer to the same range of keys, but if there are too many you merge them into a bigger file

1622015-11-05T14:42:57 <jgarzik> jonasschnelli, sqlite3 branch is at a temporary end state, unless further speedups can be found

1712015-11-05T14:47:40 <jonasschnelli> sipa: Right. I see. I've thought together with #6917 (leveldb) it would fix the whole corruption issues. Because with 6917 i "mostly" got the "bad undo" error... but now i get 100% leveldb middle of records errror.
1722015-11-05T14:48:37 <sipa> are you sure you did #6948 together with #6917?
1732015-11-05T14:48:53 <sipa> and not only #6948?

2172015-11-05T18:29:56 <gmaxwell> jtimon: I am not suggesting it for using it with blocks. I think it would be bad for that.
2182015-11-05T18:32:31 <gmaxwell> wumpus: for all you know there is something wrong with jonasschnelli's VM and it impermisably reorders writes or ignores sync.
2192015-11-05T18:33:34 <gmaxwell> wumpus: (I would be completely unsurprised to see VM software which ignored sync to prevent vm guest OS from thrashing the host... and used userspace buffering of writes for similar reasons, and didn't guarentee them flushed when it quit)
2202015-11-05T18:34:41 <gmaxwell> wumpus: in any case, there is a clear path forward, get the corrupted data from him and check it out.
2212015-11-05T18:35:16 <gmaxwell> wumpus: based on the undo related errors before I believe his node is in the process of a reindex as he's doing these tests?
2222015-11-05T18:35:31 <gmaxwell> If it isn't the VM itself that is the difference in your test conditions, then it may be reindexing.
2232015-11-05T18:40:02 <wumpus> true, that may be the case
2242015-11-05T18:41:57 <wumpus> going to test master+#6948 on real-windows tomorrow, if I can't get corruption, I'll just ignore the VM results for now

2262015-11-05T18:47:14 <jgarzik> some VMs definitely do that
2272015-11-05T18:55:35 <jonasschnelli> Okay. This might be the case (although I never expected any corruption while hard power off a VM).
