Armory - Discussion Thread

[doug_armory]

Well, now I really screwed up. I updated to 0.92.99.7-testing, old database was deleted, and now armory keeps crashing as soon as it starts building databases, I tried like 6 times

Can you try the final 0.93 release? A last-minute bug that primarily (but not exclusively) affected OSX was patched this afternoon. I'm reasonably certain it'll stop your crashes. If it doesn't, file a support ticket and send us traces and logs ASAP.

Thanks!

Hey, the Changelog page is all empty :/

Have any of the developers looked at using qr codes to transfer the signed transactions? It seems this guy has done it already on Ubuntu...

If only I was smart enough to do the same thing haha.

Technically, this is possible.
In some cases the data needed for signing is huge, up to megabytes. It would then be close to impossible to transfer via QR, and that user might be in serious trouble then. Like with many many inputs from mining, for example. Even with non-extreme but large transactions it would not be very practical.

There are several ideas how to do "airgapping" securely. How I understand it, we are waiting for addon-ability for Armory first, then these optional and sometimes controversial options would be possible.

You are right but in most cases, this wouldn't be a problem. The Qr-code's size will increase, so you might need a an Android phone with a good camera.

I would like to see this.

getting dependency error not satifiable:  libstdc++6(>=4.7) in Ubuntu 12.04 32 bit on attempted install of 0.93

do we have to install 0.93 on both online and offline pc's?

Note that 0.93 can't go online in x86. Also, it requires C++11 so you'll need a libstd that is recent enough. You can probably get that package from the LTS backports repo.

Only the online machine

Ugh, I just realized I bet we broke the 12.04 offline bundle with this release.  I bet no one tested that... we really need to widen the testing net better.  In the future, we might offer quadruple bounties for the first bug found in each of a bunch of categories.  That would include testing the offline bundles, and lots of corner case features...

I might need to update the offline bundles and re-release 0.93...

Biggest possible size (according to Denso spec) is 23,648 bits with version 40 (177x177). That's 4,296 alpha-numeric characters (according to Wikipedia)..

Thanks for telling! I found a page with full possible sizes and bits. If anyone is interested, http://blog.qr4.nl/page/QR-Code-Data-Capacity.aspx.

I was looking through the webshop example, is polling the best way to get new transactions to your wallet with armoryd.py?

Hi,

I have a problem:

1- I hibernate the laptop with Armory opened.
2- I back from hibernate.
3- Armory doesnt syncronize. (To syncronize again I need to restart Armory).

OS: Ubuntu 64

Nothing can be done about this. Some of Armory's stack is forced in the RAM through mlock. Hibernation copies the entire RAM into the swap partition. Since that would defeat mlock's purpose, mlock'ed memory is not copied imaged in on hibernation. Armory won't be able to recover from that.

Hi,

I was testing the last version of Armory and I think this was fixed, right?

No this is still here and we don't plan on getting rid of it.

Strange. I can't reproduce the problem anymore.

Hi, thank you for the latest release and for making the most secure bitcoin software.

However, I still don't understand why under settings there is a path for Bitcoin install dir and Bitcoin home dir?  Maybe it's just me, but don't these locations sound exactly the same?

Install directory.  Home directory.  Same thing.  It's not like there's a directory called "home" anywhere.  Maybe a little description is in order?

There needs to be an option for the increasing number of SSD drive owners to install to a different drive.  --dbdir= in the shortcut link is not something most users will know how to do.

Finally, most importantly, Armory needs to stop relying on the Bitcoin Core client to function.  I think I read that a future release will remove this dependency.  I look forward to that!

You may want to consider some updates to the online dllinks.txt file at some point to reflect all of this...

E.g., removing the 32 (bit) flag from all of the Armory 0.93 versions (keeping it for ArmoryOffline though), and removing 12.04 from the Armory & ArmoryOffline Ubuntu lines until/unless you intend to distribute your own libstdc++6 (FYI a newer version isn't in the backports repo unfortunately).

It's a judgement call though....

Will Bitcoin 0.10.0 become available through the secure downloader, now that Armory officially supports it?

Speaking of updates to the dllinks.txt file (that's the file that would need updating and re-signing for 0.10.0 to become available).

Yes it will, the problem is that it's not split up by Armory version, so updating 0.10 in the secure downloader would push it to the all the 0.92.3 users as well, who haven't upgraded.  I figured I would remove all the torrent code and push 0.10 all at once, but I'll give it some time for people to upgrade Armory first.

Good point.  You should wait!  I will download it manually as I used to do, it is not *that* hard to check the signatures manually

how's the Ubuntu 12.04 version coming along?
