Con Kolivas cc14f166 2012-12-02T19:29:54 Make gen_stratum_work more robust by using a dynamically allocated array for the header in case bogus data is sent by the pool to avoid overflowing a static array.
Con Kolivas f94cff77 2012-12-02T18:06:55 Microoptimise and remove redundant copy of strdup function in calloc_strcat.
Con Kolivas 53c9cdaf 2012-12-02T16:56:36 scrypt_diff now returns a uint64_t
Con Kolivas d8e18994 2012-12-01T23:36:17 Support monitoring and reporting much higher diffs for scrypt mining, truncating irrelevant zeroes from displayed hash.
Con Kolivas 0ae02c6e 2012-12-01T08:26:31 Since we will be using calloc_str to put a string into it, convert the function to calloc_strcat which does it automatically.
Con Kolivas 01eb807c 2012-11-29T13:00:02 Revert "Handle crash exceptions by trying to restart cgminer unless the --no-restart option is used." This reverts commit 68c881fde72f7aa92224cf4e4ba67a5af868dafc. Does not reliably restart on crashes often enough and makes debugging more difficult.
Con Kolivas bc4f6d92 2012-11-29T12:58:42 Count longpoll and GBT decodes as queued work since the count otherwise remains static.
Con Kolivas 1746e471 2012-11-29T12:49:28 Use the string helper functions to create gbt blocks of any length.
Con Kolivas 217be6ed 2012-11-25T00:37:46 Do away with the flaky free_work api in the driver code which would often lose the work data in opencl and simply flush it before exiting the opencl scanhash.
Con Kolivas c34ff367 2012-11-24T23:08:14 Use base_work for comparison just for cleanness in __copy_work
Con Kolivas 73671ab3 2012-11-24T18:45:02 Remove all static work structs, using the make and free functions.
Con Kolivas 3ab92ef6 2012-11-24T13:35:00 Add pool no. to stale share detected message.
Con Kolivas 850d07df 2012-11-24T12:58:58 Add info about which pool share became stale while resubmitting.
Con Kolivas 31e43944 2012-11-24T10:58:46 Do not use or count or use the getworks submitted which are simply testing that pools are still up. This was increasing share leakage and making stats not reflect real work.
Con Kolivas 2d35ac25 2012-11-24T10:47:20 Track all dynamically allocated memory within the work struct by copying work structs in a common place, creating freshly allocated heap ram for all arrays within the copied struct. Clear all work structs from the same place to ensure memory does not leak from arrays within the struct. Convert the gbt coinbase and stratum strings within the work struct to heap ram. This will allow arbitrary lengths without an upper limit for the strings, preventing the overflows that happen with GBT.
Con Kolivas aa72db36 2012-11-18T23:04:01 Provide rudimentary support for the balancing failover strategies with stratum and GBT by switching pools silently on getwork requests.
Con Kolivas 40a3331e 2012-11-18T22:27:03 Remove unintentional block of code in reuse_work.
Con Kolivas 9ad02fe3 2012-11-18T21:48:44 Support workid for block submission on GBT pools that use it.
Con Kolivas 61f4e9d6 2012-11-18T17:22:48 Revert "Discard all work on longpoll, not just work cgminer recognises as stale." This reverts commit 1470eea903266fc5cef8e722859dca55ae460183. Work block update makes this unnecessary.
Con Kolivas f14bf5b1 2012-11-17T22:06:49 Merge pull request #326 from pshep/error_counters Error counters
Con Kolivas 4039ee7a 2012-11-18T16:53:39 Convert pool not responding and pool alive message on backup pools to verbose level only since they mean a single failed getwork.
Con Kolivas 52b86b51 2012-11-18T16:38:24 Update work block on the longpoll work item before calling restart threads to ensure all work but the longpoll work item gets discarded when we call discard_stale from restart_threads.
Con Kolivas 1470eea9 2012-11-18T15:54:14 Discard all work on longpoll, not just work cgminer recognises as stale.
Con Kolivas 88983306 2012-11-18T15:50:04 Do not attempt to remove the stratum share hash after unsuccessful submission since it may already be removed by clear_stratum_shares.
Con Kolivas d15515be 2012-11-15T13:09:00 Check against a double for current pool diff.
Con Kolivas b3864d1a 2012-11-15T09:18:58 Support for fractional diffs and the classic just-below-1 share all FFs diff target.
Con Kolivas 1832dbd7 2012-11-11T22:57:48 Make header larger on gen stratum work to accomodate \0 at the end.

Con Kolivas 89cb1419 2012-11-11T20:53:27 Use stratum block change from backup pools as an alternative to longpoll for pools that don't support LP.
Con Kolivas 38eb4ee4 2012-11-11T18:09:46 Check share target diff for best_share to be calculated when solo mining.
Con Kolivas 7993095e 2012-11-11T17:53:20 Round some more static string arrays to 4 byte boundaries.
Con Kolivas 17aa87be 2012-11-11T17:37:58 There is no need for the static arrays to be larger than required, so long as they're 4 byte aligned to appease ARM.
Con Kolivas 149781cf 2012-11-11T17:14:55 Revert "Change default log interval to 3 seconds for faster screen refreshes since vardiff will prevent massive on screen hash updates in the future." This reverts commit f1f6b31faff2cca9a111407c28d4bf9af28284aa. Screen update frequency is what I wanted to change, not the log interval.

Con Kolivas 878f4d53 2012-11-11T16:05:39 First pass through testing for GBT should not set probed to true since we are about to probe again.
Con Kolivas 598ee76d 2012-11-11T09:51:37 Hash1 is only used by the deprecated cpu mining code and never changes so remove it from the work struct and bypass needing to process the value for all other mining.
Con Kolivas f1f6b31f 2012-11-07T23:32:01 Change default log interval to 3 seconds for faster screen refreshes since vardiff will prevent massive on screen hash updates in the future.

Con Kolivas 0465fef5 2012-11-05T23:22:36 Discard record of stratum shares sent and report lost shares on disconnection since they will never be reported back.
