 84 2015-11-05T13:36:02  <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
 85 2015-11-05T13:36:05  <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
 86 2015-11-05T13:36:27  <jonasschnelli> then i stopped bitcoin-qt and started bitcoin-qt from https://github.com/bitcoin/bitcoin/pull/6948
 87 2015-11-05T13:36:36  <jonasschnelli> did a power off hard shutdown
 88 2015-11-05T13:36:50  <jonasschnelli> restarted win8.1 ... restarted bitcoin-qt from 6948
 89 2015-11-05T13:36:59  <jonasschnelli> -> resulted in "Corruption: error in middle of record"
 90 2015-11-05T13:37:01  <wumpus> but if that doesn't fix it I don't know, I really don't know anymore
 91 2015-11-05T13:37:44  <jonasschnelli> switch away from leveldb
 92 2015-11-05T13:38:05  <wumpus> maybe FlushFileBuffers on windows doesn't really flush the buffers
 93 2015-11-05T13:38:09  <wumpus> no, I don't want to hear that
 94 2015-11-05T13:38:42  <jonasschnelli> I'll do the test again ... maybe i missclicked somewhere.
 95 2015-11-05T13:38:44  <wumpus> well, unless, have you tried this with another database at all?
 96 2015-11-05T13:39:15  <jonasschnelli> sqlite3 was to slow i heard... i'd though about trying it with the unstable sqlite4 branch
 97 2015-11-05T13:39:19  <wumpus> it would be somewhat interesting to try this with jgarzik's sqlite patch. At least to have a measurement point.
 98 2015-11-05T13:39:53  <jonasschnelli> jgarzik uses seqlite3 which is certenly much slower then leveldb... sqlite4 sounds promising... and unstable.
 99 2015-11-05T13:40:20  <wumpus> for this experiment I don't care about slowness -  I wonder if *anything * can handle this kind of corruption succesfully
100 2015-11-05T13:40:59  <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?

107 2015-11-05T13:43:50  <jonasschnelli> Maybe you'd like to start with the Win8.1 VM... you need VMWare Fusion 8 (or higher)
108 2015-11-05T13:44:06  <fanquake> I'd take copies of the ones your using to test #6948
109 2015-11-05T13:44:11  <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
110 2015-11-05T13:44:26  <fanquake> I'm actually setup somewhere with a decent internet connection atm, so downloading won't be so hard.

141 2015-11-05T14:31:01  <jgarzik> jonasschnelli, RE databases and comparison...  I should have a fast replacement ready in a few weeks, https://github.com/jgarzik/pgdb2
142 2015-11-05T14:31:45  <jgarzik> jonasschnelli, sqlite is probably too slow for useful benchmarking
143 2015-11-05T14:31:46  <jonasschnelli> jgarzik: hah. Let me check out the code...
144 2015-11-05T14:32:28  <jonasschnelli> jgarzik: what about sqlite4? It's says on the architecture website ("It is very fast, faster than LevelDB...",)
145 2015-11-05T14:33:12  <jonasschnelli> And riding on one of the best maintained database layers would be nice... but right,.. it might be the wrong type of database
146 2015-11-05T14:33:37  <jgarzik> jonasschnelli, https://sqlite.org/src4/doc/trunk/www/design.wiki definitely looks like they are catching up to modern design
147 2015-11-05T14:34:32  <jonasschnelli> I have also though about your "pgdb2"-like-approach, ... but it seems to be a hard way.
148 2015-11-05T14:34:56  <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. "
149 2015-11-05T14:35:12  * jgarzik knows what log-structured is.  What is a merge database, I wonder
150 2015-11-05T14:36:25  <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?)
151 2015-11-05T14:36:40  <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)
152 2015-11-05T14:37:03  <jgarzik> jonasschnelli, sounds like using sqlite4 is simple - take my branch and add 'env' argument to each function call.
153 2015-11-05T14:38:48  <jonasschnelli> jgarzik: do you have plans to work towards sqlite4 and report some benchmark numbers? Or should i give it a try?
154 2015-11-05T14:39:16  <jonasschnelli> but i really like to find a solution to fix the current leveldb corruption issues...
155 2015-11-05T14:39:45  <jonasschnelli> although, i don't care about windows enough,.... but i care about users complaining about the issue and stopping full nodes.
156 2015-11-05T14:40:29  <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.
157 2015-11-05T14:41:18  <jonasschnelli> Okay. pgdb2 looks nice btw!
158 2015-11-05T14:41:54  <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

162 2015-11-05T14:42:57  <jgarzik> jonasschnelli, sqlite3 branch is at a temporary end state, unless further speedups can be found
163 2015-11-05T14:43:06  <jgarzik> jonasschnelli, I task switched over to BIP 1xx and pgdb2

171 2015-11-05T14:47:40  <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.
172 2015-11-05T14:48:37  <sipa> are you sure you did #6948 together with #6917?
173 2015-11-05T14:48:53  <sipa> and not only #6948?

217 2015-11-05T18:29:56  <gmaxwell> jtimon: I am not suggesting it for using it with blocks. I think it would be bad for that.
218 2015-11-05T18:32:31  <gmaxwell> wumpus: for all you know there is something wrong with jonasschnelli's VM and it impermisably reorders writes or ignores sync.
219 2015-11-05T18:33:34  <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)
220 2015-11-05T18:34:41  <gmaxwell> wumpus: in any case, there is a clear path forward, get the corrupted data from him and check it out.
221 2015-11-05T18:35:16  <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?
222 2015-11-05T18:35:31  <gmaxwell> If it isn't the VM itself that is the difference in your test conditions, then it may be reindexing.
223 2015-11-05T18:40:02  <wumpus> true, that may be the case
224 2015-11-05T18:41:57  <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
