Re: QR codes. not on linux source buildI have tested QR codes with my Linux QT build of v0.6.4.4
The \ receive coins \ show QR – no QR image is shown.
[/quote]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.

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.
[/quote]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.
[/quote]Thanks Kevlar.

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.

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

can you add me to the repository. user: groll
I will take a look but as usual my time is limited.
-
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.
-
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.

[/quote]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.

[/quote]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

Tuck, that is so against the rules for the forum, but I think we need to keep it. It’s hilariously appropriate.
Kevlar - I am giving you a high-five across the huge land-mass between us.
-
I left PRIMECOIN_CHECKPOINTSYNC_H in there as the code for this is from Primecoin. I do not mind leaving references to Primecoin as a nod to Sunny lest we forget his contributions.
However you can have the honour of renaming it if you like?
Let’s debug.
The function CheckSyncCheckpoint that the assert is in is called from here…

On Wrapper0feathers suggestion I have created a branch pre-ACP commit which will run. This can be used for testing the client whilst we look at the compatibility between Sunny’s code and 0.8.5.

Complite 0.8.5 success. Run it ,Need to resynchronization transaction records. ;)

I have updated the checkpoint data on both 0.8.5 branches. The non-ACP branch will be deleted eventually but for now it allows us to test.
The data comes from the debug.log as shown below and allows us to enter the correct number of transactions since the last hard coded checkpoint. The number of transactions a day is just an estimated amount taken from our totals transactions and the number of days since launch.
