Feathercoin 0.8.5

Bushstar

The client can show QR codes but only on Windows! I have not compiled this into the Mac client yet, sorry :(

Poor Mac users, they pay twice the price for a computer and then get forgotten half the time. The Mac client does not handle the Feathercoin URLs either. I believe an installer is required for that to make the client responsible for handling the Feathercoin URLs. If anyone is familiar with this then please let me know.

Re: QR codes. not on linux source build

I have tested QR codes with my Linux QT build of v0.6.4.4

The \ receive coins \ show QR – no QR image is shown.

Wellenreiter

The same here.

I’ve built on Linux, with QR code enabled, but no QR Code shows up.

Okay that makes sense then. Totally my bad, I run wallets on my Mac and Linux machines but try to keep my Windows stuff away from crypto, so there’s no way I could know. Sorry for my confusion!

Yeah, I’ve done it plenty of times in the past. Used to make VPN clients that would launch and get their credentials from a protocol handler on Mac, Linux, and Windows.

Everything you need to know is here. Pretty straight forward. Don’t need an installer, you just need to run the client once.

I don’t have a mac any more though, so some brave soul who does will have to take the next part on.

Have you built another client like Litecoin to see if the QR codes are working there?

I just want to make sure that it is the client and not your computer.

Litecoin v0.8.5.1-8-gffd7439-beta

Linux (13.10) compiled versions from source -

Litecoin -Doesn’t have the option for QR codes, right click in receive coins.

whereas Feathercoin 0.6.4.4 QR code menu option is there on right click, but nothing happens.

Bushstar

Thanks for that Wrapper.

Wellenreiter and Lizhi I have added both of you again. Apologies Lizhi, I thought I had added you before.

The client compiles but is still broken by the changes to the key so is currently no good. The commit that broke compatibility is linked in below.

https://github.com/bitcoin/bitcoin/commit/dfa23b94c24aae6466152fccbe896ba5dc0e97b4

groll

can you add me to the repository. user: groll

I will take a look but as usual my time is limited.

wrapper

Hi Groll / Bush,

Re: Crowd development.

If you can think of any way I can help, test compiling, looking into some function / patch you need more info on / stuck on (history) or some such. Shout out.

Bushstar

groll, I have now added you to the repo. The commit that broke ACP and CAlert is as follows.

https://github.com/bitcoin/bitcoin/commit/dfa23b94c24aae6466152fccbe896ba5dc0e97b4

This made way for HD Wallets. We could simply reverse the commit but I would say that we make ACP and CAlert compatible with the changes to OpenSSL and include HD Wallets in this release.

Before the client downloads the block chain it appears fine.

Thanks Wrapper. There should be a whole lot of testing soon. Right now the client compiles but crashes when the blockchain starts downloading with the following assert error. Be careful with this release as the wallets are not backwards compatible afterwards. Make sure you have a backup first.

Hierarchical Deterministic Wallets (11-2-2012)

https://en.bitcoin.it/wiki/BIP_0032

The Bitcoin reference client uses randomly generated keys. In order to avoid the necessity for a backup after every transaction, (by default) 100 keys are cached in a pool of reserve keys.

Deterministic wallets do not require such frequent backups, and elliptic curve mathematics permit schemes where one can calculate the public keys without revealing the private keys. This permits for example a webshop business to let its webserver generate fresh addresses (public key hashes) for each order or for each customer.

This seems like an easy one to fix.

The line of code in question is:
[quote]
assert(mapBlockIndex.count(hashSyncCheckpoint));
[/quote]

So stick a breakpoint on that line and examine your call stack. What’s calling it? What’s hashSyncCheckpoint value and where is it coming from? Put another breakpoint in mapBlockIndex.count (where is that defined?). What is the expected value? More details please!

Also, your header exclusion compiler macro name is funny: #ifndef PRIMECOIN_CHECKPOINTSYNC_H #define PRIMECOIN_CHECKPOINTSYNC_H
