Hello, will the freeze option work even if other addresses' balance is 0 ? Thanks

I looked over the code and I am fairly certain Electrum will not spend frozen adresses even if other adresses are at zero. It looks to me that all the frozen addresses are removed as possible inputs.

For now please downgrade SIP and PyQT. I will see if I can find a fix for the problem itself.

Yeah, having debug mode ON in a final release sure doesn't look good. Can we expect this version to be reliable with real money use?

Debug mode is not enabled; the fact that a console windows opens does not mean the application runs in debug mode. This is purely to provide you, the end user, with the option to use the command line flags.

I've updated the plugin and webservice to fully encrypt all data using AES.

No standalone version for 1.7?

Let me quota you the correct passage of the announcement I wrote, it's a bit long so you might have missed it.

Quote from: Tachikoma
Because of the internal changes there are currently problems creating the "single .exe build" of Electrum. Only the installation option is available. The good news is that command line options for this version are working and the style for the Lite GUI is packaged again.

Awesome, I have not been able to produce a single .exe build on 1.7 so this is most welcome if you can pull it off Smiley
867  Bitcoin / Electrum / Re: [ANNOUNCE] Electrum - Lightweight Bitcoin Client on: March 17, 2013, 07:02:49 PM
The 1.6.2 upgrade notification definitely works.

I have problem though.  I'm on the windows version and whenever I open my wallet I also get a separate console window.  If I close it, my wallet closes as well.

This is intended for now. Enabling that console windows makes it so Electrum can accept command line options; without that window it won't accept it and things like portable mode or opening an other wallet are not possible.
That sounds strange... I've written and used several Windows programs that accept command-line options without a console window. From where does this constraint stem? Are you calling AllocConsole()?

It is a result of PyInstaller what is currently used to build the windows packages. If you disable the console it won't accept command line arguments. If you have more experience in such methods please check out the build scripts and see if you can help us improve the windows packages.

1.7 Released

Electrum 1.7 Released

After a few months of hard work we are proud to announce Electrum 1.7. A lot has changed both the inside and outside of the application. Let me run through the list.

Plugin support
The classic gui can now be extended with plugins. Developers who want to add new features to Electrum or let Electrum interface to third-party services are now welcome to do so. Some core functionality in 1.6 and lower has now been refactored into a plugin.

Electrum ships with the following plugins by default.

  • Alias - Retrieve aliases using http.
  • Label sync - Syncs your labels between Electrum installs/instances.
  • Point of Sale - Adds a window with QR Code and more payment information.
  • QR Scanner - As the name implies
  • Virtual Keyboard - Adds a virtual keyboard to the password dialog.

Interactive console
The wall has been turned into a virtual console. The provided python environment gives users access to the wallet and gui. Most
electrum commands are available as python function in the console. Custom scripts an be loaded with a "run(filename)"
command. Tab-completions are available.

Offline wallets
Offline wallets now work in a way similar to Armory:

1. User creates an unsigned transaction using the online (watching-only) wallet.
2. Unsigned transaction is copied to the offline computer, and signed by the offline wallet.
3. Signed transaction is copied to the online computer, broadcasted by the online client.
4. All these steps can be done via the command line interface or the classic GUI. ("Load transaction" from "Import/Export" tabs in settings)

Private key exports
Private keys can be exported from within the classic GUI. For a single address, use the address menu (right-click). To export the keys of your entire wallet, use the settings dialog (import/export tab). It will dump your private keys to a csv file.

Multi-sig transactions
It is possible to create, sign and redeem multisig transaction using the command line interface. This is made possible by the following new commands: dumpprivkey, listunspent, createmultisig, createrawtransaction, decoderawtransaction, signrawtransaction. The syntax of these commands is similar to their bitcoind counterpart. For an example, see Gavin's tutorial: https://gist.github.com/gavinandresen/3966071

Wallet location for Windows changed
The location of the Electrum folder in Windows changed from LOCALAPPDATA to APPDATA. Discussion on this topic can be found here:
https://bitcointalk.org/index.php?topic=144575.0. This process should be automatically done for you but if a wallet is found in both folders it might ask you to resolve it yourself.

Address generation
The wallet waits for 2 confirmations before creating new addresses. This makes recovery from seed more robust. Note that it
might create unwanted gaps if you use Electrum 1.7 together with older versions of Electrum.

Various changes
Because of the internal changes there are currently problems creating the "single .exe build" of Electrum. Only the installation option is available. The good news is that command line options for this version are working and the style for the Lite GUI is packaged again.

Both setup and stand-alone are now available.

Also if somebody could let me know if the "upgrade notification" in 1.6.2 was working that would be great Smiley

Downloads available on the Electrum site

871  Bitcoin / Electrum / Online label syncing plugin in Electrum 1.7 on: March 17, 2013, 12:02:55 PM
LabElectrum

Starting with Electrum 1.7 there will be a plugin to sync your labels between multiple instances or installs of Electrum.

The syncing works in two parts.


Setting it up

If you want to help me test the plugin you can use it as follows. Go to the LabElectrum site and sign up for an account. The service does not require email confirmation  so feel free to improvise. Once signed up copy the API-key to your clipboard. Download the latest 1.7 release of Electrum and go to the plugins tab and enable the "Label Sync" plugin.



Enter your API-key key. If this is your first time using the plugin use the "Force upload" to sync all upload all your current labels. If your labels are already uploaded you can simply press "Done" and restart Electrum to retrieve them all from the server.

To test if it worked you can login to the LabElectrum site again and see if you see a wallet id and the amount of transactions you have uploaded.



Privacy

Now please note the following matters regarding your privacy:

  • The unique identifier for your wallet is your master public key hashed.
  • Your transactions, addresses and labels are send to the server in encrypted form.

Future plans

The ability to not only decrypt and view your labels online but also edit them.
872  Bitcoin / Electrum / Re: Electrum - Bitcoin client for the common users (friendly and instant) on: March 17, 2013, 11:45:02 AM
Thanks!  Where can I contribute bitcoins?  I don't see an address on electrum.org or in your sig.

Electrum itself is not accepting donations at this moment. Best is to spread some Electrum love to one (or multiple) server operators.


What does it mean if blockchain says that it doesnt know a transaction id?

Yesterday i sent 0.000001BTC to a new wallet as a test. Its in my list of transactions but no confirmation. I tested other full servers and they even dont show the transaction in my transaction list. So i thought that will happen when the first conf is there. But now i copied the t-id into blockchain.info to find out how many unconfirmed transactions are in there but its unknown there too. I mean shouldnt it appear in the list of unconfirmed transactions then?

So does this mean that the server im currently on didnt send the transaction forward or whats the reason?

It sounds like your transaction was not broadcasted over the network. Do you remember which server you used?

I thought till now that a full server would be better, because of the word... but pruning is the better solution i read in a manual for server admins for electrum?

Pruning is better for server admin since it requires less server resources. When restoring from seed it's important to select a full server, once that's done it shouldn't matter as much.

Service fee is tussen de 10/15%.    Relatief duur maar de service is TOP.

Het is makkelijk om over je eigen service te zeggen dat hij top is, het is beter als je klanten dat zeggen natuurlijk Smiley
874  Bitcoin / Electrum / Re: Turned on comp today and electrum.dat is gone on: March 16, 2013, 05:46:15 PM
Try installing and opening it with gedit.

(On debian or ubuntu apt-get install gedit most likely)


Just out of curiosity; did you lose your seed or did you not save it to begin with?
875  Bitcoin / Electrum / Re: Turned on comp today and electrum.dat is gone on: March 16, 2013, 05:16:14 PM
By the way I just moved and am having trouble locating my seed

You are the only one responsible for your seed, we can't help you locate it.

Can you possibly explain that differently so that I can be sure I am following you correct.

If your wallet is damaged and you need to restore from seed do the following:

  • Open a terminal
  • Issue the command electrum -w ~/.electrum/new-wallet.dat
  • Select "Restore"
  • Enter your seed.

If the wallet is now working again close down electrum and move your new wallet to be the default wallet.
Code:
mv ~/.electrum/new-wallet.dat ~/.electrum/electrum.dat

You can now boot Electrum without any flags again.

By the way the forum has an edit command. I recommend you use it, it increases readability.

Is this how I get around the problems I was having installing python on ubuntu 12.04?  I can just run flatfly electrum 1.5.6?

No. Flatfly is a Windows build. What is the problem with python on Ubuntu?
877  Bitcoin / Electrum / Re: Electrum - Bitcoin client for the common users (friendly and instant) on: March 16, 2013, 03:05:57 PM
If its needed to have python on the pc... is there a portable python? I already searched and only found "portable python" or web2py but these seems to be only for developing, not for running python apps.

No no, you won't need Python. Python should be bundled.

Versions under 1.7 could have a single Electrum.exe with everything build into this one exe file. I can't manage to replicate this behaviour on 1.7.

For now on 1.7 you will need more files then just that Electrum.exe. There will be an installer still; and you can move the files you install to any location or computer and it should still work. There are just more files to take care off now.

I hope this explains it. 
878  Bitcoin / Electrum / Re: Electrum - Bitcoin client for the common users (friendly and instant) on: March 16, 2013, 02:04:55 PM
I'm not sure the stand-alone can be made at this point, I have given up on trying. I hope somebody else might step up and build it.

Does this mean the only portable solution is still version 1.5.6 from flatfly where you have to specify the electrum.dat?

You can still install electrum to a usb key for instance. But for now just a single . Exe doesn't seem possible.

The 1.7 windows build should have command line support enabled again. The portable and wallet flags should work from that version on.
