Howard Chu 69b59186f3 Add ARMv8-A AES support 
More than twice as fast as plain C code. Note that both ARMv7 and
ARMv8 can be further improved with better use of NEON.

Also tweak ARMv7 multiplier
 2016-09-16 01:45:49 +01:00
Howard Chu b8c03a5f10 Remove blocks_per_sync limits 
The code used to cap at 5000 blocks per sync. It also treated 0 as 1.
Remove these checks; if specified as 0 do no periodic syncs at all.
Then the user is responsible for syncing in some external process.

Howard Chu d6f5d543a5 Fix Issue #855 
Use the same size dirty list for both 64 and 32 bit.
 2016-06-07 23:38:47 +01:00
Howard Chu f1e70d15ca Only log 1/N skipped blocks 2016-04-29 16:50:51 +01:00

Howard Chu 590c43988c Make fast_refresh interruptible 2016-04-29 15:33:28 +01:00
Howard Chu 687855d658 Set refresh height earlier 
Do it before the generate() call so the value actually gets stored.
 2016-04-29 15:33:28 +01:00
Howard Chu 2fb00c0666 Fix 19fe8ae3ef 
Don't prompt for restore-height on generate-new-wallet
 2016-04-29 04:51:02 +01:00
Howard Chu 2b0fa05f0d Another take on migration 
Delete old indices and recreate them, rather than updating them
Maybe not quite as slow as before.
 2016-04-24 17:46:50 +01:00
Howard Chu 19fe8ae3ef Add --restore-height option 
For specifying the block height from which to start a restore
 2016-04-17 15:25:46 +01:00
Howard Chu b6e42c3276 Speed up new wallet refresh 
Use the current blockchain height as the refresh_from_block_height.
 2016-04-17 15:25:46 +01:00
Howard Chu b7140daea2 Add GET_HASHES_FAST rpc, use it in wallet 
When m_refresh_from_block_height has been set, only hashes will be
retrieved up to that height, instead of full blocks. The same will
be done for "refresh <height>" when the specified height is beyond
the current local blockchain.
 2016-04-17 15:25:46 +01:00
Howard Chu 66b1e13aa7 mdb_drop optimization 
If we know there are no sub-DBs and no overflow pages, skip leaf scan.
 2016-04-09 20:44:05 +01:00
Howard Chu c14f9efd52 Migration 
Migrate from DB version 0 to version 1 on startup
 2016-04-08 03:11:05 +01:00
Howard Chu aaaf9e2e6d Fix get_tick_count() on Windows 
GetTickCount used in 52056dcfc4
only has ~10-16ms resolution. Use higher rez timer to get 1ms rez.

Howard Chu 118dd69dd5 Use DUPFIXED for block_info and output_txs 
Saves another ~150MB or so on the full blockchain
 2016-04-05 20:55:16 +01:00
Howard Chu 6225716f3c More outputs consolidation 
Also bumped DB VERSION to 1
Another significant speedup and space savings:
Get rid of global_output_indices, remove indirection from output to keys

This is the change warptangent described on irc but never got to finish.
 2016-04-05 20:55:12 +01:00
Howard Chu 7c5abdc3a3 Use DUPFIXED for output_keys 
Saves another 90MB on 200000 block import.
Had to bring back compare_uint64 for this, but it's safe since
this table is always 64-bit aligned.
 2016-04-05 20:54:42 +01:00
Howard Chu 8e9d8e3364 Use DUPFIXED for tx_indices 
Small space savings, no measurable speedup

Howard Chu a74348e115 Add destructor for readtxns 
Only if we created the readtxn. Was missing cleanups from exceptions before.
 2016-03-16 11:34:13 +00:00
Howard Chu 6b0a903177 Small cleanups 
Only one return and TXN_POSTFIX_RDONLY() per function
Only log rtxn_start if the rtxn wasn't already active
 2016-03-15 13:35:31 +00:00
Howard Chu 01c1512f22 More for 92dd4ec6d6

the writetxn from reader threads

 2016-02-18 21:31:21 +00:00
Howard Chu 7c86c5997d Use boost::thread instead of std::thread 
std::thread crashes on (at least) ARMv6 g++ 4.8/4.9

Howard Chu 1537477c9f Use cursor in get_output_key 2016-02-17 04:05:29 +00:00
Howard Chu f2faf8cdd9 Use MDB_APPEND mode where possible 
When keys are contiguous and monotonically increasing, this gets
denser page utilization (doesn't leave padding in page splits).
Can't be used for keys that are inserted in random order (e.g. hashes)
In total this only saves around 1.5% of space compared to original
DB code. The previous patch accounted for 0.8% savings on its own;
the blocks tables just aren't that big.
 2016-02-17 04:05:29 +00:00
Howard Chu 090b548c3b Use cursors in write txns 
Saves a bit of seek overhead. LMDB frees them automatically
in txn_(commit|abort) so they need no cleanup.

hyc 9428d53d6f Strip redundant includes 
In particular, <boost/program_options.hpp> blows up daemon.cpp.obj,
making it too big to compile in debug mode on Win32. Even on a
release build it drops daemon.cpp.o on Linux from 31MB to 20MB.
This has no effect on the final linked binary size.
