Con Kolivas 8fcc67f3 2012-12-09T13:39:37 Remove dependency on mstcpip.h for windows build by making curl version >= 7.25.0 mandatory on windows builds, and use curl functions for keepalive whenever possible instead.
Con Kolivas 68f1b2c4 2012-12-08T22:14:47 Set successful connect to true on auth stratum to allow summary on exit from single stratum pool.

Con Kolivas fc5d3a0e 2012-12-03T09:52:46 Suspend stratum connections to backup pools when there is no requirement to potentially grab work from them.
Denis Ahrens 271b05ab 2012-12-02T11:39:20 setting the name of the threads for linux,freebsd,openbsd and osx code is borrowed from bitcoins util.c, so it is already tested

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 ee8609d9 2012-11-29T12:48:17 Provide helper functions calloc_str and realloc_strcat to create and extend arbitrary length arrays based on string length.

Con Kolivas 6f4c47eb 2012-10-29T11:58:58 Make stratum socket fail more robust on windows by disabling the send buffer. Reuse the same curl handle forcing a new connection instead of risking derefencing. Add information about submission failure to stratum send.
Con Kolivas aa97e87a 2012-10-28T09:15:45 Use keepalive with stratum sockets to improve its ability to detect broken connections.
Con Kolivas d9276557 2012-10-27T23:20:10 Show only the URL in the status bar to avoid long prefixes making for extra long lines.
Con Kolivas 6d3c880a 2012-10-22T22:48:12 Make sure to check pool stratum curl exists under lock before attempting any recv to not risk dereferencing upon attempting to reinitiate stratum.
Con Kolivas e575763a 2012-10-22T22:06:00 Avoid redefining macros and align to 4 byte boundaries.
ckolivas bb4bec98 2012-10-17T09:34:32 Use select on stratum send to make sure the socket is writeable.
Con Kolivas 99adf397 2012-10-16T19:47:31 Failure to calloc in bin2hex is a fatal failure always so just check for that failure within the function and abort, simplifying the rest of the code.
Con Kolivas b3d42589 2012-10-16T19:22:48 Provide locking around the change of the stratum curl structures to avoid possible races.
Con Kolivas e5babfa2 2012-10-15T11:40:32 Watch for buffer overflows on receiving data into the socket buffer.

Con Kolivas 5226a399 2012-10-11T00:06:44 Look for null values and parse correct separate array entries for url and port with client reconnect commands for stratum.
Con Kolivas 7c04a00e 2012-10-10T23:56:24 The command for stratum is client.reconnect, not mining.reconnect.
Con Kolivas 783af876 2012-10-10T23:41:29 Implement rudimentary mining.reconnect support for stratum.
Con Kolivas 974f65c6 2012-10-10T23:22:24 Ignore the value of stratum_active on calling initiate_stratum and assume we're always trying to reinitiate it, and set the active flag to false in that function.
Con Kolivas 07605fad 2012-10-10T23:07:33 stratum auth can be unset if we fail to authorise on subsequent calls to auth_stratum which undoes the requirement of setting it in one place so set it in pool_active.
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 a8d69302 2012-10-05T12:37:29 Move stratum sockets to curl infrastructure with locking around send+recv to begin support for proxies and ssl.
Con Kolivas deb0a9b6 2012-10-04T23:18:33 Windows doesn't work with MSG_PEEK on recv so move to a continuously updating buffer for incoming messages.
Con Kolivas 77c5a006 2012-10-04T21:00:32 Alloca is unreliable on windows so use static arrays in util.c stratum code.
Con Kolivas c113534f 2012-10-04T15:35:28 Begin support for mingw stratum build. Conflicts: configure.ac

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 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.

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.
