Namecoin 15/10/13 Hard Fork - update before 8th Dec

[snailbrain]

as per libcoin's thread: http://dot-bit.org/forum/viewtopic.php?f=2&t=1295

DETAILS of Hard Fork: https://bitcointalk.org/index.php?topic=322939.0

Hard-fork is set to happen at block 150000 (~76 days from now). Before that bad name_* transactions are allowed, but won't be processed (i.e. won't be saved to name DB). After that they will be rejected, as well as blocks containing them.

At first start nameindexfull.dat will be rescanned (slow - be patient). If something goes wrong, delete it to force another rescan.
nameindexfull.dat is checked by version (rescanned if below 0.3.72).

If you can, please donate to the coder for his time :

Please post all "issues" here... check the code if you can.. (before someone makes official)

Thanks again for the quick fix and your as well as the coder's time! However, I have to disappoint you regarding the bug: Deleting nameindexfull.dat to force the rescan did not fix the issue for me. After the rescan, the code still crashed, and when restarted it still didn't find any names.

don't forget to make backups

Yes I have. With the namecoin-qt git of an hour ago (which included some changes relative to yesterday, but I'm not sure about this fix in particular) the error is still there. Guess I'll have to wait a little longer.

we have not tested this with the fakeupdates.. but in principle it should work..

libcoin is being very helpful in PM...

but maybe should wait on merging into official repos until everyone completely agrees everything is O.K.

(not completely fixed all issues yet)

There is a discussion going on behind the scenes whether to go along with the current fix or improve it. TBH I would prefer to have it in public.

Feel free to dig into the current fix:
https://github.com/namecoin-qt/namecoin-qt

Normally I would say pull requests are the way to go but this important matter should be discussed and double checked first...

I'll commit a small patch soon (removing block number check at line 1575)

Have been speaking with libcoin and he has been extremely helpful regarding the issue..
Both agree that the code is a bit messy, but there is a lot of work to be done on that front, on namecoin as a whole.
hopefully this patch will fix the problem at hand..
BUT...
as phelix said, it would be best to get as much input as possible from "everyone"
