Spoke about it with Thomas and he mentioned that there is a possible exception that can be raised in wallet.verify_message. Look at line 501 in wallet.py.

Probably the easiest way to debug is to remove lines 535 and 538 and let it raise the exception if it happens.

signmessage / verifymessage don't seem to work for me, verify always produces False - could someone else test as well?


I am aware of the issue; there are two problems:
 - a module was mising in setup.py this is fixed in git  (see recent commits)
 - verifymessage fails with compressed keys (the new format used by the satoshi client). the result is that it will return False on a string signed by the satoshi client using a recent wallet. this was reported by nanotube. it is not fixed yet.


Verifymessage still seems to always fail for me... I'm not using compressed keys, I'm just trying a basic test, signing and verifying myself.

Does it work on Linux?

What's the status on this? Can anyone verify that verifymessage works? Doesn't seem to do it for me.

EDIT: I'm not using compressed keys.

Code:
electrum signmessage 1EPtpYzA43o3Mj66Hd18TFUjHc6eReqfDq HelloAll
--> G+ueV7eOuAkLcPgdy99cL2v+tRBv+oFDqPUTjJtBxyeL8dNWHKSYAvQBt2BF7ZwFh6eeuvqzxfqmZzCRNFAROEo=

electrum verifymessage 1EPtpYzA43o3Mj66Hd18TFUjHc6eReqfDq G+ueV7eOuAkLcPgdy99cL2v+tRBv+oFDqPUTjJtBxyeL8dNWHKSYAvQBt2BF7ZwFh6eeuvqzxfqmZzCRNFAROEo= HelloAll
--> True

Try it yourself. If you want to lead or end a string with extra spaces or want to use double spaces inside a string make sure to quote it. I.e. "Hello  All", " Hello All " etc.

No problem!

I had trouble getting Electrum to connect, not sure if that's isolated to my Windows VM though. Are you available for a chat on IRC by the way? I love to have you more closely involved with the project you are doing an awesome job at the windows client.

Thanks! I would be honored to have a chat about it. However, unfortunately, I will not be available on IRC until later this week.

About the client not connecting from your VM: does the previous build (0.60) connect successfully?

I think it's not a problem with your build. I just tried a fresh install on my Ubuntu VM and I got the same problem It seems there is a problem somewhere in the code that prevents it from connecting on first launch when no valid wallet is found.

I could finally prepare a temporary Windows computer with all required
dependencies and compile a 1-click build of Electrum 1.0.

Both regular and portable versions are now available.
Same download location as usual: http://dre.redmartian.org/elecwin.htm

**Special thanks to genjix and tachikoma for their precious help!**

Note: this build still defaults to the "pro" GUI.
If you want to give the new "lite" GUI an early try,
just drop to the console and run "electrum -g lite".
But it's still under heavy development.

No problem!

Mac os 10.6.8

18SNiRKvuHfni31RJpA9rWahnWzS222h9E

This happened on Electrum 1.0 when I first tried it last week, and on 1.01 which I just tried after reading this thread. IIRC the console msg for the 1.0 crash was the same, the gui_lite module not being present.

The Electrum dmg will only run on OS X >= 10.7. You could still install it manually if you want.

downloading the client (for any platform)

can't run on ubuntu Sad

Code:
qrs@localhost:~/Desktop/electrum$ sudo python setup.py install
[sudo] password for qrs: ********
Traceback (most recent call last):
  File "setup.py", line 6, in <module>
    from lib.version import ELECTRUM_VERSION as version
  File "/home/qrs/Desktop/electrum/lib/__init__.py", line 1, in <module>
    from wallet import Wallet, format_satoshis, prompt_password
  File "/home/qrs/Desktop/electrum/lib/wallet.py", line 30, in <module>
    import aes
ImportError: No module named aes


Please use the apt packages, that will work fine. Or do
Code:
 sudo apt-get install -y python-sip; sudo pip install slowaes; sudo pip install ecdsa 

That will solve the python.py install issues.

BitcoinPayflow should work. They host the bitcoind, you just request addresses over an API and they forward the funds. It's just a matter of trusting a third party with your payments.

For what it's worth, I've been using them for quite some time and so far, so good.

ThomasV : how far along is the code towards being able to reference multiple servers? (e.g. I want my client to connect with at least m of n selected servers before doing anything)

or genjix maybe knows this better ... is there any dev work underway to achieve this? 

I have indicated that I would like to work on this problem, but haven't been graced with free cycles lately. I think it's a significant problem too. I will free up some time and try to make it happen sooner than later.

Awesome! This is a very welcome feature, it's just something out of my current comfort zone. I'm glad you are stepping up Smiley

As far as I know nobody is working on this just now. Only work on the server connection that is planned is making it less obtrusive. Basically as a casual user it will connect to servers and reconnect to different ones if one stops working without user interaction.

Feel free to send in a pull request though if you feel like coding up something.
1070  Bitcoin / Electrum / Re: [ANNOUNCE] Electrum - a new thin client on: August 24, 2012, 06:17:14 PM
Is this still the place to get the code to build the server from?

For ABE, yes.
1071  Bitcoin / Project Development / Re: Bitpay RubyGem on: August 24, 2012, 09:35:10 AM
Since you said you are learning ruby I would have some pointers.

1. Ruby uses camel-case for class names and underscores for variables and methods. Also try to use two spaces for tabs and use them consistently.
Code:
class BPLIB > class BpLib
bpCreateInvoice -> bp_create_invoice
etc.

You can read more about the Ruby style in this website.

2. You can make this a one liner if you would want to

Code:
options = @options.merge(options)
options[:price] = price
options[:orderId]= orderid
options[:posData]= posData

options = @options.merge(options).merge({:price => price, :orderId => orderid, :postDate => posData})

3. I would probably rewrite this bit using has_key? since I find it increases readability.

Code:
  postOptions.each_with_index do |opt,index|
    if options.include(opt[index])
      postdata[index] = options[index]
    end
  end

postOptions.each do |key|
  if @options.has_key?(key)
    postdata[key] = @options[key]
  end
end

4. Is the code actually working? It seems you define postdata after you try to fill it.

Hope these tips help Smiley

When I follow the Windows source installation instructions:

Quote
Install PyQt4
Install Electrum-1.0.zip
execute 'python electrum'

I get:

Code:
Traceback (most recent call last):
  File "electrum", line 23, in <module>
    from electrum.util import print_error
ImportError: No module named electrum.util

Never had this problem before...

Can you try it using the latest master. I don't have a Windows environment to test on so I'm not quite sure what's going on here.

Any of the tickets left?

Quote from: genjix
We sold 10% of the 700 tickets available so far. I'm about to close the issuing of the first 100 tickets.

I would say, yes! Smiley

I'm aware of that. Problem is that if you look at the QR-url source here you can see the correct path. Somehow the site is not updating it.

I guess it just took time -- it's all working for me now. e4a_install.py and the e4a zip file are both accessible. The QR code for the Python script is also updated. Thanks!

Hah you are right! It's all working now Smiley Long live waiting!
1075  Bitcoin / Electrum / Re: Electrum for Android on: August 20, 2012, 04:45:50 PM


Still not working for me.

Neh there is still something forked up. It seems github pages might not be compatible with symlinks. I will have to find some time to figure out why that is.

note that you do not need to use a symlink.
you could also just name the file directly "e4a"

Tried that as well, but I still can't download it. Will try it again when I'm on my work computer.

afaict, the url you use in e4a_install is still wrong: http://electrum-desktop.com/files/

1078  Bitcoin / Electrum / Re: Electrum for Android on: August 20, 2012, 01:46:44 PM
I get a 404 error when accessing e4a_install.py on my desktop. My phone is able to download it through the QR code, but the Python script tries to download the the file http://ecdsa.org/electrum/e4a/e4a-0.52.zip which also doesn't exist.

this is because ecdsa.org now redirects to electrum-desktop.com
could someone update the url there?


URL updated and scripts added. I can't confirm it to work on my own phone because SL4A freezes when I try to run the script (even on the old location). So please let me know if you have more luck.

I find the new logo ugly and meaningless. what do you guys think?

I concur. Maybe we can design something specific for Electrum.

I agree, I also question why? What was wrong withe the old one?

It was the bitcoin logo.
1080  Bitcoin / Electrum / Re: [ANNOUNCE] Electrum - a new thin client on: August 20, 2012, 10:55:32 AM
I will definitely NOT use the client with the new (awful) logo!
