implement extranonce.subscribe into cgminer

We are looking for someone to implement and test a small stratum protocol extension called [login to view URL] (as described here [login to view URL]) into cgminer. Basically it is mainly only a copy-paste&test job since the implementation has already been done in sgminer and bfgminer. (btw: we've already proposed this to ckolivas and other official cgminer developers, but they're too busy) For us it is especially important for this feature to be implemented in cgminer since the majority of ASIC device manufacturers burns cgminer into their devices and in some cases it is hard to put a custom (patched) version later into such devices. This feature has already been included, for example, in the latest sgminer. Search for "extranonce" here: [login to view URL] or in official sgminer GIT source code at [login to view URL], it has also been implemented in BFGMiner ([login to view URL]) The job includes: - fork latest [login to view URL] into your own github repo; - add [login to view URL] patch; - change the way [login to view URL] is handled; instead the current default=on (optional "--no-extranonce") you should add "--extranonce-subscribe" so that one must explicitly enable [login to view URL] ("--extranonce-subscribe" : true) ... similar to the way it was added to BFGMiner ([login to view URL]); - please do it in such a way (preferably in single commit or similarly) so that others would be able to pull it very easily into the various other cgminer forks with a single pull request; - make win32 binaries and test the binaries against [login to view URL] and [login to view URL] to make sure that [login to view URL] is working and extranonce changes are received and used properly without disconnect from stratum servers. Payment: 0.75 BTC (or equivalent in USD or EUR at BTC/USD or BTC/EUR exchange rate at payment) when all the above is done (this is an easy job). Thank you and let us know if you need any more info! p.s.: one attempt to do this was already done by badman74, but this work hasn't been finished, nevertheless you can take a look at it here: [login to view URL]
