multipool: Squashed commit (v2) commit a9d3c1ffdb71d2a4985749acba3d424161154ab4 Author: Tanguy Pruvot <tanguy.pruvot@gmail.com> Date: Thu May 21 05:39:24 2015 +0200 multipool: last changes before squashed merge and fix net diff on wallets.. was longpoll specific commit a63f0024f3f1fb52d2c4369518bf87c33a9e16ae Author: Tanguy Pruvot <tanguy.pruvot@gmail.com> Date: Thu May 21 05:02:27 2015 +0200 update api sample for the protocol 1.5 commit adda14b22edde6485932be56550166478f6f00dd Author: Tanguy Pruvot <tanguy.pruvot@gmail.com> Date: Thu May 21 04:43:25 2015 +0200 stats: store pool number in scanlog commit e1a0274b01c29409ce16f9096b9985a35cf78ba7 Author: Tanguy Pruvot <tanguy.pruvot@gmail.com> Date: Thu May 21 03:36:15 2015 +0200 api: switchpool and new pool stats variables (API v1.5) add accepted/rej by pool, wait time on conditional, net diff and rate also add scantime per pool config option and do some pool cleanup.. commit 1a30450ad2a5e068983531b9d2a96629b970c1e8 Author: Tanguy Pruvot <tanguy.pruvot@gmail.com> Date: Wed May 20 06:39:09 2015 +0200 prevent concurrent pool switching and limit condtionnal wait messages to the first thread/device commit e3922c7a331a3ad2730bc83082fcd6b2547542f5 Author: Tanguy Pruvot <tanguy.pruvot@gmail.com> Date: Wed May 20 05:39:45 2015 +0200 add some pool rotate options, like pool time-limit update sample pools.conf for time rotation commit 312bd905412d49fd5a9f9e7ff2bc72b23edf38ed Author: Tanguy Pruvot <tanguy.pruvot@gmail.com> Date: Wed May 20 04:31:19 2015 +0200 do not try to restart threads from threads Start inconditionally the stratum and longpoll threads, these threads are just waiting a tq_push() if unused... so add some checks to know if vars are set for the right pool commit d4a9428fefdd9e9d70c3c8231f10961e7cd41760 Author: Tanguy Pruvot <tanguy.pruvot@gmail.com> Date: Wed May 20 01:06:31 2015 +0200 pools: add name and removed attributes also increase max defined pools to 8 to be tested on windows.. commit d840d683ecb2cc4767f0a0612b8359c52d4bad29 Author: Tanguy Pruvot <tanguy.pruvot@gmail.com> Date: Tue May 19 22:33:11 2015 +0200 parse json config file pools array commit d6c29b1f7f6b786c56e1f0cb8a90305f06cc7aec Author: Tanguy Pruvot <tanguy.pruvot@gmail.com> Date: Tue May 19 03:29:30 2015 +0200 multi-pools: prepare storage/switch of credentials for the moment: - allow the storage of multiple -o params (and user/pass) - allow a failover pool on connection failed - switch to the next pool with the "seturl" api remote command - longpoll to stratum switch (reverse to check...) todo: mix stratum/getwork, new api commands, json config... commit 2d6b3fddf6631d7df1ac6ca74eee91c33a3c09ee Author: Tanguy Pruvot <tanguy.pruvot@gmail.com> Date: Fri May 22 08:26:40 2015 +0200 multipool: increase stability, but not 100% perfect several problems fixed: - submit to the pool set in work (source pool) - longpoll curl timeout could be too high and could lock the switch - mutexes cant be copied on windows (stratum global var to fully remove later) I linked the -T timeout option to curl and tried to remove all fixed timeout values commit 6fd935c369cf33949dab98c8b09b2ca8cab3e7ea Author: Tanguy Pruvot <tanguy.pruvot@gmail.com> Date: Fri May 22 11:23:07 2015 +0200 stratum: remove last rpc_ vars in stratum thread commit ee9c821525be303282e5dab512ffd2ae81ad524f Author: Tanguy Pruvot <tanguy.pruvot@gmail.com> Date: Sat May 23 03:53:50 2015 +0200 stratum: do not alloc empty merkle tree commit 69852a2874bd18c4ed1daa9180a10d12976424dc Author: Tanguy Pruvot <tanguy.pruvot@gmail.com> Date: Sat May 23 04:25:12 2015 +0200 stratum: properly free jobs on disconnect Signed-off-by: Tanguy Pruvot <tanguy.pruvot@gmail.com>
