termcoin's Issues

Encrypt Wallet by Default (or at least prompt)

Upon initialization of a new wallet, the user should be prompted for an encryption passphrase.

Zero passphrases from memory once they're no longer needed

Discussed here: https://news.ycombinator.com/item?id=7080339

Wrong behavior when spaces in the address label

Choosing a label with a space causes bugs.

For instance the QR code generated actually contains the balance.

I suggest not parsing the displayed ui or at least to use a more robust parsing.

Suggestion: use async library

First off: awesome project!

I couldn't help but notice that some functions have a lot of nested callbacks. Maybe it would be an idea to abstract the nesting out via an async library like async. This way you could separate the logic more and use optimizations like parallelizing batches of queries to bitcoind.

Package fails to install on NPM

I got this working on a remote server, so my node install must be broken. Thanks, and sorry for the false report!

The NPM package seems to be failing when installing. It looks like package.json isn't in the archive. I cleared my NPM cache and did everything that I could think of to test that this isn't only on my environment, so hopefully I'm not posting something useless!

Runs for awhile, then crashes with (Error: Not found)

Works great for awhile, then when I come back I see this error:

Error: Not found.
    at /home/runvnc/coinado/node_modules/termcoin/node_modules/coined/node_modules/tiny/lib/tiny.json.js:419:23
    at /home/runvnc/coinado/node_modules/termcoin/node_modules/coined/node_modules/tiny/lib/tiny.json.js:402:12
    at Object.wrapper [as oncomplete] (fs.js:459:17)

If I delete the db from ~/.termcoin, it stops giving that error. Otherwise pm2 just keeps trying to restart and it keeps giving that error.

So, I am loading termcoin as a module and running startServer. Is it possible I am doing something wrong, or is this a known error? I think this results from calling getBlock. But basically I call startServer and then use listReceivedBy and createAddress. I need a light wallet, and thought this was a good option since its Node. Not sure if there is a way to make this work, maybe I need to just call it as an external cli since that's what it is, or if there is a new issue from protocol changes, or if I should just wrap another external wallet.

Appreciate any comment you have, thanks.

Proof of Stake Coin causes crash

Generating interest with a proof of stake coin causes termcoin to fail

Option to increase the delay prior trying to connect to the newly launched daemon.

I'm using termcoin on an old P2 266 box, where it takes 6 minutes and 5 seconds to have a freshly loaded Litecoin daemon instance listening on the RPC port.
After launching termcoin it terminates after 30 seconds with the following error:
bin/termcoin:2734
if (err) throw err;
^
Error: connect ECONNREFUSED
at errnoException (net.js:904:11)
at Object.afterConnect as oncomplete

As far as I can see there's a hardcoded limit of 30 reconnect attempts prior terminating:
if (err.code === 'ECONNREFUSED' || err.message === 'socket hang up') {
if (++attempts === 30) {
return callback(err);
}

I think that it would be handy if there's an option to increase that limit from the commandline for users on slower boxes like. :)

Thank you!

Remove bind to "q" when typing in a password

Could you remove the bind to "q" for closing the program when typing in a password? its impossible to encrypt the wallet with a password containing "q"

Error: Unsupported method 'getbalance'

I'm trying to connect to a mining pool, but termcoin is throwing an error:

$ termcoin http://user.worker:[email protected]:8332    

/usr/lib/node_modules/termcoin/bin/termcoin:2712
    if (err) throw err;
                   ^

Is this a problem with the pool, or with the client, or with my configuration?

Running Two Instances of Termcoin Causes Unexpected Errors

When running two instances of termcoin simultaneously, on the same machine, some unexpected state management bugs can occur.

Request: Ability to disable mouse interactions

As currently installed, running termcoin via ssh in iTerm does not allow for copying the addresses to the clipboard.

The text does not make it through when using "Copy Address" in the interface, and there is no obvious way to highlight the raw text for local copying.

Log panel empty on OpenBSD

The logs panel is empty for me on OpenBSD. Tested with node 0.10.24 and 0.10.25. I have a debug.log file with lots of data in $HOME/.bitcoin which is 600 and owned by the same user running termcoin.

Debugging suggestions?

[coin]d and UI issues

Hi,

First of all, thanks for the great wallet!

With that said, I've got the following problems:

1. When I navigate to 'send' and hit Ctrl-E, I get a list of potential recipients, though when I navigate to 'From' say, Ctrl+E no longer works. Is this expected behaviour?

2. Running termcoin -c litecoin worked well the first time I ran it, though after encrypting my wallet, quitting and restarting termcoin, I get the following:

% termcoin -c litecoin
Starting new server on port 9332...
/usr/lib/node_modules/termcoin/bin/termcoin:22
if (err) throw err;
^

Error: Loading block index...

Waiting a few seconds and running termcoin again then yields the following:

if (err) throw err;
^

Error: walletpassphrase "passphrase" timeout

Stores the wallet decryption key in memory for 'timeout' seconds.
This is needed prior to performing transactions related to private keys such as sending litecoins

Arguments:

1. "passphrase" (string, required) The wallet passphrase
2. timeout (numeric, required) The time to keep the decryption key in seconds.

Note:
Issuing the walletpassphrase command while the wallet is already unlocked will set a new unlock
time that overrides the old one.

Examples:

unlock the wallet for 60 seconds

litecoin-cli walletpassphrase "my pass phrase" 60

Lock the wallet again (before 60 seconds)

litecoin-cli walletlock

As json rpc call

curl --user myusername --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "walletpassphrase", "params": ["my pass phrase", 60] }' -H 'content-type: text/plain;' http://127.0.0.1:9332/

The same happens with dogecoin.

I have tried running 'termcoin -c litecoin' with an unencrypted wallet, and I get the first of the above two errors, but running it a second time yields no issues.

I'm running termcoin 0.0.8 as installed by npm.

Thanks in advance for any comments!

Keys can be encrypted with two (different) passphrases

Extending #14, it seems as if running two instances allowed me to encrypt two of my keys using a different passphrase.

Possible to use this as a library?

I was originally trying to figure out how to interface with bitcoind, then realized it may not be necessary to download 36GB to my test and dev servers, then found bitcoinjs-lib and then bcoin, then coined. Then I tried to figure out how to read a list of transactions received in the db coined uses, and found termcoin.

The way you have this set up I was able to import it. What I am hoping I can do is use things like termcoin.bitcoin.listReceivedByAddress etc. in my Node application, which would solve both my lightweight wallet and transaction query problems at the same time without requiring an external dependency.

Anyway I may just be fantasizing since this is a cli application. But thank you for making it, it is at least a good starting point. Can I use it as a library?
