Can't install..

Win7, when I have to enter an installpath, clicking 'next' gives an empty screen. Clicking 'next' again hangs the installer.

[jim618]

Hi xorgate,

Are you using a 64 bit install of Win7 ?

I ask because of this very similar bug report:
http://jira.codehaus.org/browse/IZPACK-673

On the assumption that you are, I have updated my installation files as per the bug report (it is an extra DLL to include) and created an installer for you to try out. It is at:
https://github.com/jim618/multibit/downloads

It is the multibit-0.4.2alpha-windows.exe (MultiBit 0.4.2alpha - Windows installer - for xorgate) Edit: now removed

This is an alpha version of the current MultiBit code - it is just for you to try out the installer change. If it works please wait for the next QAed version to come out for any serious bitcoin work. The next version of MultiBit should be out in only a couple of days.

(I test on a Win XP virtual machine and this installer works fine but, of course, this is no test of the 64 bit DLL).

Let me know if this fixes the problem.

Jim

[xorgate]

Yup that fixed the install issues, cheerio.

[jim618]

Great!

There is a new release of MultiBit at:

http://multibit.org


Version 0.4.2

Enhancements:
+  Added utility to migrate wallets from serialised to protobuf format.
+  'Delete wallet' now overwrites wallet file with random data before deletion (secure delete).
+  Improved error handling on startup if blockchain cannot be loaded.

Bug fix:
+  Installer now works on Win7 x64.

Scan of release checklist


Next up is:
+ dealing with any wallet migration glitches
+ getting the bitcoinj wallet encryption format agreed and working

Replay blockchain doesn't work!  Import private keys from blockchain.info.aes.json 

[jim618]

Hi Finway,

I will have a look at it. Could be something to do with replaying from the genesis block, which I must admit I do not do very often.

[genjix]

I wasn't able to get it to work on Linux I'm not too familiar with Java but it just didn't start up.

Hi Amir,
If you cd to where you installed it and do . . .

java -jar multibit-exe.jar

the console log should give me an idea of what the matter is.

Replay blockchain doesn't work!  Import private keys from blockchain.info.aes.json  

I have fixed the bug with replaying the blockchain from the genesis block (which happens with blockchain.info backups).
I have also got a 'genesisBlockReplay' functional test that 1) resets the blockchain back to the genesis block, 2) connects to a peer, 3) downloads a couple of dozen blocks, 4) checks the blockchain size.  This should prevent this sort of error getting past me.

The fix will appear in the next version (0.4.3) which will probably be on Monday.

Can you PM me the multibit_debug.log and multibit_console.log that will be in:

?

Thanks to whoever donated to the MultiBit donation address on the 4th of July.

Happy (Fiat) Independence Day !

Hmm, I've only seen that HeadlessException when running Multibit (tests) on a server with no graphics capability. It's when it cannot open a window due to there not being a graphics environment it can hook into.

The Linux version I use for testing is a Ubuntu 10.4 VM (it works on later Ubuntus I know).

I am sure you just wanted to install it and run it and have a look and not answer all these questions !
What variant of Linux are you running and is it Gnome or KDE ?

I will also beef up the feedback to give a bit more useful info to the user.

[jim618]

I think you might have a headless java runtime environment.

You could try installing the Openjdk Java 7 with:

sudo apt-get install openjdk-7-jdk


Edit: bumped to open jdk Java 7 rather than 6

[genjix]

woo! that was it. thanks

[jim618]

Great - glad you have got it starting ok.
You have inspired me to improve the checking of things at startup and improve the documentation.

:-)

Edit: I have put in a bit more error handling code at startup so the user gets more useful information in the logs. Also the Linux install help now explains how to install Java. http://multibit.org/help.html

I thought I would give you all an update on the wallet encryption work.

I have started a code branch labeled "v0.5" where all the password work is going into. There will probably be a couple more releases of the 0.4.x MultiBit code (bug fixes etc) before a v0.5.0 comes out.

There are various strands of work to do for the encrypted wallets:

1) User interface changes.
So far I have just added some menu options:

edit: removed

I'll be working on these over the next week or two as they can be done in parallel with items 2 and 3 below.
(Spec: https://docs.google.com/document/d/1_8vwkQcv-Tcfx9aU-lKbWgDhAsOkpug3wiHyTo2sy0Y/edit#heading=h.kd3tu753qxq)


2) Encryption/ decryption code
This is not finalised yet but I have some demo code using scrypt and AES (this describes how the password you type gets turned into an encryption key and how that encryption key actually encrypts the bitcoin keys respectively).

Code:
https://github.com/jim618/multibit/blob/v0.5/src/main/java/org/multibit/crypto/EncrypterDecrypterScrypt.java
Test:
https://github.com/jim618/multibit/blob/v0.5/src/test/java/org/multibit/crypto/EncrypterDecrypterScryptTest.java


3) Storing the encryption data in the wallets
There is a draft google doc with the format for storing the encryption information:
https://docs.google.com/document/d/1bWtBjzqzSubQZ926sUz5iTeMEK30aNNQXFM9z562m-s/edit
This is has had one review cycle with the bitcoinj devs but needs more work yet. Then there is actually implementing the change to the protobuf wallets.

4) Testing
Due to the nature of this work, it needs a thorough testing before letting everyone use it. I will produce a release candidate and ask people to test it out before it is released generally.
