[ANN][NMC] Namecoin Wallet (QT) with integrated Name Registration v3.75

[maxpower]

3.64 crashes on load under OS X 10.8.4.

Can you post or PM me the crash report (the one that OS X wants to send to Apple)?

[mnyonpa]

Done.

[maxpower]

Done.

Thanks! This is a threading problem that's happening while the code is initializing your wallet, but it's unclear to me whether it's a bug in the threading code or a problem with your wallet. In either case it will probably be fixed in the next version, when the Bitcoin 0.8 code is merged in (which includes totally rewritten threading code). Unfortunately, I've never seen this particular crash before, so it's hard to say what the underlying cause is.

Is this a new wallet, created by Namecoin-Qt? Or did you copy in a wallet.dat from another client?

[mnyonpa]

Thank you very much!

Problem solved!

I just deleted all the ~/Library Application Support/Namecoin stuff created by namecoind, then put wallet.dat from backup there, rebooted and started Namecoin-Qt. Now it’s redownloading the blockchain which I suppose will take some time, but it shows my namecoins correctly.

Great! And good point, I think the namecoind build that's out there from OS X is built from a different version of the codebase than Namecoin-Qt, so Namecoin-Qt may not be able to read some of namecoind's data, and vice versa.

Want to build your own Namecoin-Qt on Windows?

Give this a try: https://github.com/phelixnmc/namecoin-qt EasyWinBuilder Namecoin

Download, run easywinbuilder/__all_easywinbuilder.bat and follow instructions.

The code itself is unchanged in comparison to Snailbrain's version.

Why does my windows client keep doing this? If I restart it, it synchronizes but leave it for a while and I come back to this.

[mnyonpa]

Just curious. Until downloading blocks around 90000~100000 the client was really unresponsive, but then no longer so.

Just curious. Until downloading blocks around 90000~100000 the client was really unresponsive, but then no longer so.

It's probably because those first blocks have little or no tx data stored in them so the client is going full tilt validating blocks and it is difficult for interrupts to get processing time ... probably better to just wait until you up to date as there is not much you can actually do with a new client (and wallet) until that point anyway.

New Namecoin EasyWinBuilder version here: https://github.com/phelixnmc/namecoin-qt

It is creating a disassembly hash of Namecoin-Qt, please let me know if you get the same hash
(see https://bitcointalk.org/index.php?topic=252931.msg2766894#msg2766894)


Also it includes a patch that made downloading of the blockchain 8 times faster on a hard disk based system (tested for the first 20,000blocks). Also it's not thrashing the disk any more and is generally more responsive. 

Please review and tell me if you consider my changes safe (they are all stolen from Bitcoin). I think the main problem was repeatedly flushing some databases to disk.

Note that I have not tested this intensively yet. Backup your wallets!

Are you going to push that into main? khal needs all the help he can get but not sure if this is the right way to be going about it.

[Apocalyptic]

Thanks snailbrain, nice to see some work being done on Namecoin. I think khal should update http://dot-bit.org/Main_Page to reflect the recent progress (especially the project tasks section which is way outdated)

Well, the performance improving changes are only six lines: https://github.com/phelixnmc/namecoin-qt/commit/9a832fa4b010420990578e18dd0753e9d13366b6

The EasyWinBuilder changes pretty much only make things compliant again with the Bitcoin-Qt directory structure.

I am also a little worried about us having two diverging Namecoin branches. We should bring them back together as soon as possible.

I'm well aware of this ...

Bug report:

I have updated DNS configuration for one of the registered names and inserted a .me domain into Translate name field. But on save a dot was appended to the name (it became "smth.me." although I wrote "smth.me"). I corrected it using “Custom configuration” tab but it still cost me 0.005 NMC, and thus I believe it’s a bug.

[bitpop]

I think that's just a fqdn and correct. Dns has dots on the end

More precisely here, it's the boost library headers you're missing.

I downloaded the whole blockchain in a little less than 1.5 hours (ssd, i3, -dbcache=1500). So I will call this v3.64GT 
Other than this there are no changes to Snailbrain's v3.64.

If you get a hard system crash (blue screen of death) it may be slightly more likely be necessary to redownload the blockchain. Your wallet should be as safe as before.

Test with care and backup your wallet

Windows Users:

I would very much appreciate if somebody could rebuild and verify the disassembly hash and thus the validity of my binary file/hash / zip hash:

Code:

Hash of Qt binary [experimental]...
File hash sha256:
3e821775c7fd9a52e28a62bae37cfb2459e5d9eb110e7d244908f86dfd4cae2a *../release/nam

Hash sha256 of disassembly [may take a while]:

phelix got: a2b3ca0dd00a3b95ee4772379336e963ebbe2341d69ba1839739893a5edd5c80

How to do it:
1.) Download the .zip file on github
2.) run __all_easywinbuilder.bat and follow instructions  (you will need to install MinGW and Qt manually!)
3.) wait for downloading, unpacking of dependencies and for building of Namecoin daemon and Namecoin Qt
4.) The scripts will come up with hashes like above. Post them here.
5.) Download my binaries and unpack.
6.) Open a command line, cd to the easywinbuilder directory
7.) run: dahash pathtotheunpackedbinaries\namecoin-qt.exe
8.) Post the output here (hopefully the disassembly hash will match).
9.) Verify the hash of the zip file
 open freshly installed MinGW shell
 cd /driveletter/yourpathtothezipfile
 shasum -a 256 namecoin-qt-winbin-0.3.64gt.zip
10.) Check that the dlls in the zip are the same as the ones in your release directory

You have then verified that my binaries are built from the github files without modification.
People then will not have to trust me alone for the binaries.
