Add support to BlockchainDB and BlockchainLMDB for batch transactions.
Add profiling to block and tx processing and DB operations.
Improve block and tx processing efficiency by less repeat hashing.
Move LMDB storage to "lmdb" subfolder.
- Upon startup, if old LMDB files are detected, abort with a message for the user to move them to subfolder or delete them.
Update and fix log statements and formatting.
new update of the pr with network limits
more debug options:
discarding downloaded blocks all or after given height.
trying to trigger the locking errors.
debug levels polished/tuned to sane values.
debug/logging improved.
warning: this pr should be correct code, but it could make
an existing (in master version) locking error appear more often.
it's a race on the list (map) of peers, e.g. between closing/deleting
them versus working on them in net-limit sleep in sending chunk.
the bug is not in this code/this pr, but in the master version.
the locking problem of master will be fixed in other pr.
problem is ub, and in practice is seems to usually cause program abort
(tested on debian stable with updated gcc). see --help for option
to add sleep to trigger the error faster.
Update of the PR with network limits
works very well for all speeds
(but remember that low download speed can stop upload
because we then slow down downloading of blockchain
requests too)
more debug options
fixed pedantic warnings in our code
should work again on Mac OS X and FreeBSD
fixed warning about size_t
tested on Debian, Ubuntu, Windows(testing now)
TCP options and ToS (QoS) flag
FIXED peer number limit
FIXED some spikes in ingress/download
FIXED problems when other up and down limit
commands and options for network limiting
works very well e.g. for 50 KiB/sec up and down
ToS (QoS) flag
peer number limit
TODO some spikes in ingress/download
TODO problems when other up and down limit
added "otshell utils" - simple logging (with colors, text files channels)
3ece158 make fallback compatible with newer slow-hash (Riccardo Spagni)
709bbc5 replaced 64-bit multiplication in difficulty.cpp with a portable version (Riccardo Spagni)

Usage:
default is lmdb for blockchain branch:
$ make release
same as:
$ DATABASE=lmdb make release
for original in-memory implementation:
$ DATABASE=memory make release
COMMITS:
- Add compile-time support for both db implementations: in-memory and LMDB
NOTE:
The default should be changed to lmdb when this is merged upstream
unless we're 100% sure the LMDB implementation is ready.
