NEW VERSION 3.0.0, APRIL 5 2013

Please note that libcurl 7.29.0 has a socket leak with request failures, which can lead to BFGMiner running out of file descriptors and/or crashing if you have a dead pool! All older and newer versions of libcurl should be fine.

Also note that if you are compiling from git yourself, you must manually run configure after autogen.sh - it is no longer run automatically to be consistent with how every other software package does this.

2.10.6 is also released and promoted to stable. Note it does not support ASICs.

Human readable changelog:

• New device driver for ASIC devices, including both Butterfly Labs' BitForce SC and Avalon.
• Enhanced device driver API, enabling devices to asynchronously handle multiple slave processors. Use --show-processors to view each individually (not yet supported for Avalon).
• You can now use --request-diff <difficulty> to ask for a specific share target from pools that support BIP 23 GBT Basic Pool Extensions.
• Support for submitting found blocks to a local Bitcoin GBT server (bitcoind or Bitcoin-Qt with -server flag): just append #allblocks to the end of your bitcoind's URI.
• Stratum connection resuming support - if you lose an active stratum connection, BFGMiner will attempt to resubmit any lost shares when it reconnects.
• Android target support. You will have to compile it yourself, but it should just work - no patching needed.
• New Python RPC client example from Christian Berendt.

Full changelog

• debian: Include new api-example.py in docs
• added example for Python using the RPC API
• added SPEC file for SUSE distributions
• Bugfix: bitforce: Free initialization data to avoid trivial one-time memory leak
• Support for local submission of found blocks (GBT only)
• bitforce: RPC pgaset fanmode 0-5 for manual fan control
• bitforce: More debugging information
• Bugfix: modminer: Since RPC always includes the temperature, we don't need to add it specially
• bitforce: Expose dual temperature sensors to RPC
• bitforce: Support for up to 2 temperature sensors per processor
• Bugfix: bitforce: BFP_QUEUE: Attempt to recover from extra queue results, or the next job finishing early
• bitforce: Always send a new job ASAP after flushing the queue
• bitforce: Implement "Queue Job Pack" (ZWX) and use it for XLINK devices to avoid USB latency issues
• bitforce: Ignore INPROCESS added to ZOX response
• Implement minerloop_queue for devices that process work items too fast to keep track of which one they're currently working on
• bitforce: Split ZOX command into its own function
• Bugfix: DevAPI: Free work when preparing it fails
• DevAPI: Abstract get_and_prepare_work for minerloops
• DevAPI: Move select() logic from minerloop_async to do_notifier_select
• Clarify stratum mining.set_difficulty debug log message
• No longer call configure from autogen.sh
• Bugfix: bitforce: Ensure result_busy_polled gets set for queue mode to avoid unnecessary 10ms wait times
• Bugfix: bitforce: Use common code for end of job_get_results, so queue results don't short-circuit timing code
• Bugfix: bitforce: Ensure "OK" doesn't remain in queued results buffer
• Bugfix: bitforce: next_line needs to increment beyond the newline character
• Update README for x970 memdiff values.
• Do not scan other gpu platforms if one is specified.
• Update README for sync objects on windows.

• Clear the stratum socket whenever we are closing it since the buffer is going to be reused.
• Do not continue work from a stratum pool where the connection has been interrupted.
• Close any existing stratum socket if we are attempting to restart stratum so the pool knows the connection has gone.
• Show mechanism of stratum interruption if select times out.

• Bugfix: Stratum: Only failover to old mining.subscribe protocol if the previous attempt was the new one (fixes a flood of retries)
• Try to extract the sessionid associated with mining.notify on 3rd level array and submit it along with the userid to support mining resume, failing gracefully and restarting if the pool rejects it.
• Cope with misread sessionid on stratum for now.
• Use the sessionid as passed on stratum connect to attempt to resume a connection once and then clear it if it fails, to use a new connection.
• Move to storing the nonce1 in the work struct instead of the sessionid for the now defunct first draft mining.resume protocol.
• Only continue submitting shares with mining.resume support on stratum when the session id matches.

• Add timestamps to stratum_share structs as they're generated and copy the stratum sessionid if it exists to stratum work generated.
• Store session id for stratum if the pool supports it for future mining.resume support.
• Keep the unique id of each work item across copy_work to prevent multiple work items having the same id.

• x6500: Make mutex management cleaner by blocking device select loop during idle get_stats
• Bugfix: minerloop_async: Always refer to real thread for select loop

• Hidden --force-rollntime option for getwork pools (use like --pool-priority, after each pool definition)
• Include processor id in get_work logging
• Support for BIP23 BPE request target extension via new --request-diff option
• Hidden option to reduce "work update" messages to debug level: --quiet-work-updates

• bitforce: Get fd/mutex pointers only once per function
• bitforce: Abstract commands to bitforce_cmd1 (single-stage) and bitforce_cmd2 (double-stage) functions
• bitforce: Debuglog device information during detection
• Bugfix: Missing includes needed on Windows
• Bugfix: Use waddstr instead of wprintw to display completed device summary line, so literal %s don't get interpreted as formatting options
• Bugfix: bitforce: Avoid polling continuously between work restart and job completion
• bitforce: Use poll device API when job_get_results needs to wait
• bitforce: Use poll device API when job_start needs to wait

Will try this out later tonight.

"St. Barbara's Faithfully Glorified Mining Initiative Naturally Exceeding Rivals", or just basically a freaking good miner.

Really?

[Fiyasko]

Woah that is the biggest thing of mining software release notes ive ever seen!
Definitly gonna read through it all, and if i see something intresting ill give it a shot!

Seems legit.

I nearly fell off my chair after seeing it though.

Core dumped - lost a whole night's worth of mining.

Edit: unfortunately, I have no core file (because of ulimit).

Core dumped - lost a whole night's worth of mining.

On mine it didn't dump the core, but yesterday after upgrading to 3.0 it just sat there for about 6 hours in "WAIT" state on a dead pool... I had to be AFK and didn't notice it had entered the WAIT state... frustrating...

I fixed my bfgminer.conf so any pools that occationally go dead are the failover pools... I was using http://eligius.st as my primary pool but it shows up as dead currently... so I'm currently using https://eclipsemc.com for my primary pool.

BTW, does anyone have a comprehensive list of pools that operate a getblocktemplate server besides the above two?

Well, I answered my own question... check out https://en.bitcoin.it/wiki/Comparison_of_mining_pools for a comparison of mining pools... I'm not sure how often this is updated tho...

I was running 2 instances (2 separate machines) of BFGMiner 3.0.0 last night on Bitminter. One of them (15 fpgas) crashed around 1-2am PST. The other (2 fpgas) did not. A 3rd system running 3.0.0 on ozcoin also did not crash overnight. I've had these problems before on Bitminter, on occasion; anecdotally when it happens my web session seems to get logged off, so this suggests that there may have been some problem on Bitminter.

Of course the mining software should not crash; it should handle any 'problems' more elegantly. But I can see this being something difficult to debug since it happens so rarely and the conditions required for it are not well understood.

[Luke-Jr]

Core dumps and/or backtraces would be very helpful to debugging any crashes. Did the 2.99.x versions work stable for those experiencing this?

I've not experienced any crashing myself, but it does seem there are conditions where the SC devices have begun to stop hashing (which IMO is much more annoying than a crash), so I definitely need to put a focus on just fixing stuff for 3.0.1.

BTW, does anyone have a comprehensive list of pools that operate a getblocktemplate server besides the above two?

The getblocktemplate wiki page has a long list of pools, though perhaps it should be merged into the pool comparison page.

I've been running bfgminer-02d8f20 (a 2.99.x variant you provided). IIRC I had experienced a few crashes with that version during the March 26-29 period; again, on Bitminter and not Ozcoin or Slush (I was using all 3 during that period). But before that time, I've had no issues with bfgminer-02d8f20.

Do older versions work? Can you run:

Code:

bfgminer -D -d?

Sorry, It was a false alarm  I was tweaking two equipments via ssh and I installed the program in the wrong one

The program works ok. It's a fork of cgminer, isn't it?

Thanks for your quick reaction.

[twobitcoins]

Should there be a git tag for the 3.0.0 release?  I don't see one.

[Luke-Jr]

It began as a fork of cgminer (a CPU/GPU miner), but not to be confused with the current cgminer, which has become a fork of BFGMiner for trolling reasons.

[Luke-Jr]

Should there be a git tag for the 3.0.0 release?  I don't see one.

Forgot to push the tags to GitHub, sorry. Should be there now.

[purelithium]

I've had multiple crashes today on both my mining rigs while connected to eligius via stratum (GBT doesn't work)

How can I get crash logs to you from windows?
