d8e18994d5 Support monitoring and reporting much higher diffs for scrypt mining, truncating irrelevant zeroes from displayed hash. 2012-12-01 23:36:17 +11:00

0ae02c6ec4 Since we will be using calloc_str to put a string into it, convert the function to calloc_strcat which does it automatically. 2012-12-01 08:26:31 +11:00

01eb807ca0 Revert "Handle crash exceptions by trying to restart cgminer unless the --no-restart option is used." 
This reverts commit 68c881fde7.

Does not reliably restart on crashes often enough and makes debugging more difficult.

31e43944bc 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. 2012-11-24 10:58:46 +11:00
Con Kolivas
2d35ac2567 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.
