Had another power cut last night before applying the patch.  I have to get a ups.

Litecoin-qt was not running and it was fine.
Bitcoin-qt was running at the time and it had to re-index.

I've applied both patches, so Ill see how it goes.

Mac?

You do your own builds?

Please test my latest builds.  It is hard to know if your test results are accurate if you use anything else.

I just fired up my Virtual machine and poped my wallet.dat into a win build. Waiting for this DB sucks.

Why virtual machine?

The latest builds here have zero reports of new database corruption on MacOS X.

I'm not sure spaming users with Bitcoin-OMG builds (what does that name mean anyway -_-) is the right thing to do. It's nice you are doing this, but IMHO you try to be too quickly perhaps and I'm also not sure all testers are understanding, what they are testing really...

Prior to this bounty, the Bitcoin OMG branch has brought useful, highly tested features to a relatively stable 0.8 Bitcoin branch.  This bounty was a bit tumultuous in testing of various Mac patches and the discovery of another Mac-specific GUI crash in code that was completely stable on Linux and Windows.  I agree the process has been confusing but I believe it has been fruitful in exploring multiple solutions to the important Mac corruption issue and unexpectedly finding and fixing other bugs that may be an issue in HEAD.

Having always used Electrum I have never used Bitcoin-QT
I'm running 10.8.5 still. I could check for errors on a clean download of the block.
I did download 0.8.5.1-beta Litecoin-QT 2days ago and it seems to be fine.

Corruption of Bitcoin-Qt or Litecoin-Qt on MacOS X 10.8+ seems to be rare, affecting only particular machines for reasons we do not understand.

Tried all of the above betas. Bitcoin-QT will start up and I can use it UNLESS it is connected to the internet. Soon as it finds Peers, Boom I get a force close, and the error. Where do I go from here?  I have a few thousand worth of BTC and I need to move it.

These builds with hypothetical Mac fixes will not fix an already corrupted database.  Please consider using -reindex.  Use 0.8.5-OMG7-no-mmap2 for now.  New builds coming soon.

http://download1.rpmfusion.org/~warren/bitcoin-0.8.6-mactest1/
https://github.com/bitcoin/bitcoin/commits/0.8.6
Includes only rescriv's patch.  toffoo had corruption with this build.

Bitcoin 0.8.5-OMG7 (two variants)
http://download1.rpmfusion.org/~warren/bitcoin-0.8.5-OMG7/
https://github.com/litecoin-project/bitcoinomg/commits/0.8.5-OMG7-no-mmap
OMG7-no-mmap2 variant includes phantomcircuit's no-mmap patch and cfields mem barrier patch
https://github.com/litecoin-project/bitcoinomg/commits/0.8.5-OMG7
OMG7 - like OMG5 includes rescriv's patch and cfields' mem barrier patch

Litecoin 0.8.5.3-rc4
http://download1.rpmfusion.org/~warren/litecoin-0.8.5.3-rc4/macosx/
https://github.com/litecoin-project/litecoin/commits/exp-0.8.5.3-rc4

Read the latest status here.  There are possibly more corruption bugs. =(

Tried all of the above betas. Bitcoin-QT will start up and I can use it UNLESS it is connected to the internet. Soon as it finds Peers, Boom I get a force close, and the error. Where do I go from here?  I have a few thousand worth of BTC and I need to move it.

So this boils down to mmap() is just broken on OS X?  Wow.  Just wow.

Updated Bitcoin build to match the 0.8.6 work in progress branch at 6003954be08586092d652ca2828e86e92d96c660
This includes the patch by Robert Escriva.

Maybe try contacting one of the OSX developers responsible for the memory management ? Check the darwin-kernel maillist.

People that claim something is clearly broken, yet there are many other databases running in this same OS, might just not know how to do it properly (hard to accept it, I know). I'm not saying it's an easy problem (but maybe it is, for someone that actually knows what he is doing), neither that it is easy to reproduce.

Because it's not easy to reproduce. mmap on OS X is clearly broken in some very subtle ways, whether or not data is flushed to disk correctly almost certainly depends on the vagaries of kernel mm algorithms that can make decisions based on a lot of uncontrollable factors. That's why it's so hard to track down.

I think Sanjay may be right that on MacOS we may just have to give up on write-through mmap.

After thinking this over a bit more, and seeing new crash data from toffoo, I believe there's still a bit more to fix.

From IRC:
the issue is that while it's looping through the write, it unmaps/remaps. and if there's a write that straddles a mapping, it can be split and not flushed to disk properly by osx
robert's patch fixes that part
however, once the write is complete, it's not immediately unmapped
so at that point, the very tail may not be flushed


I'm actually wondering about a very trivial thing here. Why is no one setting up small reproduceable test cases ? There is no other way to claim bugs are fixed other than doing that. Make a test where it always fail before the patch, and that it always passes after the patch. Repeat, announce fixes.

robert's patch fixes that part
however, once the write is complete, it's not immediately unmapped
so at that point, the very tail may not be flushed

So the scenario would look like this:
- Append a new record that straddles the write boundary. Let it return from a successful Append() and don't write any new data (this is the distinction)
- Kill -9 or pull the plug before Close()
- Robert's change has caused the interim data in Append() to be flushed to disk, however the tail will not be unmapped until Close()

I've pushed a proof-of-concept "fix" here: https://github.com/theuni/bitcoin/commit/1d0e54bfb76b3891468582df97c4429174063c3c
This is just a copy/paste of what happens in Sync(), except that it's forced at the end of each logical write. Note however that Sync() first flushes to disk, so it would be sending possibly unsync'd data.

New builds again.  We need feedback from MacOS X users who were previously experiencing corruption.  This is a blocker for the release of Bitcoin 0.8.6.

As I mentioned on GitHub, I had what OMG4 considered to be a working/clean database. I didn't sync for a couple days, then downloaded and ran OMG5. Database corruption detected after attempting to sync for a minute or two. Since then, I tried opening OMG5 again at a later time and it synced just fine (no corruption detected). Downloading OMG6 now.

P.S.
Is coming from a database deemed clean by an older client (OMG4, 5, etc.) an adequate test or do we need to rebuild/resync from scratch (or the latest torrent copy) with each new version? Thanks.
