Con Kolivas ef822a25 2012-10-08T11:08:04 Detect stratum outage based on either select timing out or receiving an empty buffer and properly re-establish connection by disabling the stratum_active flag, coping with empty buffers in parse_stratum.
Con Kolivas 7a01578c 2012-10-06T10:14:30 Only hand off to stratum from getwork if we succeed in initiating the protocol.
Con Kolivas ef63ea31 2012-10-05T12:45:07 Drop stratum connect failed message to verbose level only since it's a regular probing message.
Con Kolivas fa444294 2012-10-05T12:41:59 TCP Keepalive in curl is only in very recent versions and not required with regular messages on stratum anyway.

Con Kolivas 1b7aa48c 2012-10-02T11:46:48 Initiate stratum the first time in pool_active only, allowing us to switch to it on getting a failed getwork and detecting the presence of stratum on the url at that time.
Con Kolivas d122a789 2012-10-02T10:19:45 Use 5 second timeout on sock full for now as a temporary workaround.
Con Kolivas d851bf3d 2012-10-02T10:10:52 Revert "Don't wait on select when first detecting stratum, just receive one line." This reverts commit 496af92afd3e2cfe0d507e7199bc35b17ecee766. Not quite right.
Con Kolivas 496af92a 2012-10-02T10:06:37 Don't wait on select when first detecting stratum, just receive one line.
Con Kolivas bbb092e0 2012-10-02T09:08:47 Make the stratum recv buffer larger than the recvsize.
Con Kolivas 2941febd 2012-10-02T00:00:55 Store a sockaddr url of the stripped url used in determining sockaddr to not confuse it with the stratum url and fix build warnings.
Con Kolivas eaf7ed0d 2012-10-01T22:13:20 Detect if a getwork based pool has the X-Stratum header on startup, and if so, switch to the stratum based pool.
Con Kolivas b5617734 2012-09-30T23:10:43 Provide locking around stratum send operations to avoid races.
Con Kolivas 8baac0d6 2012-09-30T23:03:45 Submit shares from stratum through the abstracted submit share function detecting what message they belong to and showing the data from the associated work, and then deleting it from the hash.
Con Kolivas fa4c9bf6 2012-09-30T22:40:41 Use a more robust mechanism to obtain a \n terminated string over a socket.

Con Kolivas 739cba28 2012-09-30T19:19:46 Rename parse_stratum to parse_method as it is only for stratum messages that contain methods.
Con Kolivas 9180a557 2012-09-30T19:11:22 Count each stratum notify as a getwork equivalent.
Con Kolivas aa6aa29c 2012-09-29T17:06:48 Check that stratum is already active in initiate_stratum to avoid de-authorising ourselves by subscribing again.
Con Kolivas 7415d7aa 2012-09-29T16:10:13 Begin implementing a hash database of submissions and attempt sending results.
Con Kolivas ac47f7f3 2012-09-29T14:16:16 Store and display stripped url in its own variable.
Con Kolivas 636f4b14 2012-09-29T11:38:52 Generate the work target in gen_stratum_work, setting default diff to 1 in case it is not yet set.
Con Kolivas 1f6fe551 2012-09-29T02:16:22 Generate the coinbase for generation of stratum based work.
Con Kolivas 1f64491f 2012-09-29T01:48:01 The number of transactions is variable so make merkle a variable length dynamically allocated array and track how many there are for stratum.
Con Kolivas 1221a80d 2012-09-29T01:03:23 Rename nonce2 to n2size reflecting that it's a size variable and not the actual nonce.
Con Kolivas 56255a0c 2012-09-28T18:01:33 Create a stratum thread per pool that has stratum that monitors the socket and serves received data.

Con Kolivas b86a8939 2012-09-28T05:30:36 Append \n in the sock_send function instead of adding it when constructing json in stratum.
Con Kolivas d416d223 2012-09-28T05:26:29 Don't keep any json references around with stratum structures.

Kano cef9731f 2012-09-12T07:44:00 CURL support for individual proxy per pool and all proxy types
Kano d5f485c5 2012-08-23T19:20:12 Pools: add RollTime info to API 'stats' and 'Stats' button in miner.php
Con Kolivas 8745ba1e 2012-08-15T09:38:45 Windows' timer resolution is limited to 15ms accuracy. This was breaking dynamic intensity since it tries to measure below this. Since we are repeatedly sampling similar timeframes, we can average the gpu_us result over 5 different values to get very fine precision.
Luke Dashjr 9c648c17 2012-07-11T20:10:52 Bugfix: Calculate nsec in nmsleep correctly The old algorithm (msecs * 1000000) - (sec / 1000000000) gets total nsec, including seconds, since the sec/1e9 should be multiplying. It's also vulnerable to easy overflows. Using ldiv gets the quotient and remainder in a single operation (at least on x86) and avoids overflow.
Con Kolivas bc0b1406 2012-07-08T21:35:19 Cope with signals interrupting the nanosleep of nmsleep.
Con Kolivas 3271be14 2012-07-06T15:01:39 Provide a ms based sleep function that uses nanosleep to avoid the inaccuracy of usleep on SMP systems.
ckolivas 1a43f795 2012-07-01T12:02:10 Mingw doesn't support asprintf, use sprintf.
ckolivas 1e942147 2012-07-01T10:44:23 Timersub is supported on all build platforms so do away with custom timerval_subtract function.
ckolivas 75ea6164 2012-07-01T10:35:08 Minor style police on util.c
ckolivas 8f954d40 2012-07-01T10:17:12 Get rid of unused result warning with asprintf.
Con Kolivas 3267b534 2012-06-28T10:43:52 Implement rudimentary X-Mining-Hashrate support.
ckolivas c5a21fab 2012-06-23T23:43:22 Extend nrolltime to support the expiry= parameter. Do this by turning the rolltime bool into an integer set to the expiry time. If the pool supports rolltime but not expiry= then set the expiry time to the standard scantime.
Con Kolivas 268039cc 2012-04-28T00:32:47 Indentation clean up.
Con Kolivas eda38299 2012-04-27T11:58:47 Create one longpoll thread per pool, using backup pools for those pools that don't have longpoll. Use the work created from the longpoll return only if we don't have failover-enabled, and only flag the work as a longpoll if it is the current pool. This will work around the problem of trying to restart the single longpoll thread on pool changes that was leading to race conditions. It will also have less work restarts from the multiple longpolls received from different pools.
Con Kolivas 9609dbc4 2012-04-20T21:09:37 Set lp_path to NULL after free for consistency.
nelisky 17b9baa9 2012-04-20T03:36:42 Removing dmalloc import left behind by mistake
nelisky 44bcb69c 2012-04-19T14:45:40 Fixing leak in resp_hdr_cb Memory is allocated for key and val, and longpoll address, when found, is stored in the header_info and prevented from being freed there. This pointer is stored during pool probing but once that's done it was just being lost. Not so visible but also leaking was the refuse reason string.
Luke Dashjr ed8382c8 2012-03-12T14:56:05 Make curses TUI support optional at compile-time.
Con Kolivas d1cddf8b 2012-02-21T22:23:07 Update licensing to GPL V3.
Con Kolivas f4284a21 2012-02-21T09:20:31 Set the lp_sent variable under lock since there will almost always be a race on setting this variable, potentially leading to multiple LPs being sent out.
Con Kolivas fe4b5e1f 2012-02-20T08:24:41 Set the lp_sent bool earlier to minimise the number of extra longpolls sent out.
Con Kolivas 39906718 2012-02-19T22:07:31 Keep track of when a longpoll has been sent for a pool and if the current pool is requesting work but has not sent a longpoll request, convert one of the work items to a longpoll as we may have switched pools but still be using the longpoll from the previous pool.

Con Kolivas 11123848 2012-02-12T17:53:50 Fix missing field initialisers warnings.
Con Kolivas 07c2ee53 2012-02-12T17:00:44 Put win32 equivalents of nanosleep and sleep into compat.h fixing sleep() for adl.c.
zefir e0fec357 2012-02-11T19:31:34 modularized logging, support for priority based logging Functions related to logging are extracted into dedicated source files for better maintainability. The existing low-level logging API is extended with a generalized scheme providing log functions log_{error, warning, notice, info, debug} that log messages based on a global opt_log_level. opt_log_level for now is set to LOG_NOTICE and might be modified via command line options or config files in future releases.
Con Kolivas 405a2120 2012-02-11T20:11:18 Remove unnecessary check for opt_debug on every invocation of applog at LOG_DEBUG and place the check in applog().
Con Kolivas b706da93 2012-02-11T14:55:12 Merge branch 'reject_reason' of https://github.com/luke-jr/cgminer into reject
Con Kolivas 5b476100 2012-02-09T21:54:23 Move from the thread safe localtime_r to regular localtime which is the only one supported on newer pthread libraries on mingw32 to make it compile with the newer ming. Thread safety is of no importance where localtime is used in this code.
Luke Dashjr f7a9897e 2012-01-26T00:07:42 Display X-Reject-Reason, when provided
Con Kolivas de4c6c29 2012-02-06T18:12:22 Provide support for the submitold extension on a per-pool basis based on the value being detected in a longpoll.
Con Kolivas e57ac017 2012-02-05T22:43:42 Remove unused get_dondata function.
Con Kolivas 36d2fa48 2012-02-05T22:39:28 Silence unused parameter warnings.
ckolivas 13fa5772 2012-02-04T20:04:49 Probe but don't set the timeout to 15 seconds as some networks take a long time to timeout.
ckolivas 1832b20c 2012-02-04T20:04:07 Revert "Some networks can take a long time to resolve so go back to 60 second timeouts instead of 15." This reverts commit c86a670ce6d264fba10a38f68d65e4b4ab27cba6. This changed more than just the timeout.
ckolivas c86a670c 2012-02-04T13:06:04 Some networks can take a long time to resolve so go back to 60 second timeouts instead of 15.
Con Kolivas bdec295f 2012-01-30T17:58:22 Set the latest network access time on share submission for --net-delay even if we're not delaying that submission for further network access.
Kano b188157c 2012-01-30T16:43:14 Resume advertising midstate support
Con Kolivas 3de7c7f9 2012-01-30T15:51:46 Stop advertising midstate support until it's fixed.
Con Kolivas 09184720 2012-01-30T15:09:58 As share submission is usually staggered, and delays can be costly, submit shares without delay even when --net-delay is enabled.
Con Kolivas 82af288e 2012-01-29T22:57:29 Revert "Fix various harmless warnings." This reverts commit a4b67f030fc0c7e2b18e79114a441c1e1617d5f8.
Con Kolivas a4b67f03 2012-01-29T21:06:17 Fix various harmless warnings.
