Reuse unused coinbase key in stratum server. Instead of asking a new key id from the wallet every time, the stratum server now provides the older one again if it hasn't been used (the local node didn't end up mining a block).
Previous code used to always get full blocks from archival peers.
Fast sync nodes shouldn't need to, other fast sync nodes have all
the history they need. This only uses archival nodes when blocks
are requested at a height that's older than the horizon.
* Beginning to rework aggsig library workflow
* more refactoring of transaction api
* whoever does round 1 first creates offset
* slate finalisation now context-free, so anyone can do it
* remove concept of transaction phase
* remove slate phase enum
* update actual send/receive code with new transaction lib workflow
* refactoring transaction building code
* serialise return transaction
* move shared functions into transactions, ensure wallet manipulation is only done outside of aggsig transaction lib
* remove unneeded wallet config from fn
* adding test functions to facilitate libwallet transaction testing
* rustfmt
* refactoring checker somewhat, adding ability to create and transactions against local copy of chain for simpler testing
* finish transaction testing functionality which verifies transactions work properly
* Remove wallet output manipulation from transaction building lib
* ensure sender expects full transaction back on last phase
* ensure sender expects full transaction back on last phase
We test if we're in fast sync or not by checking if our head is
more recent than horizon. However, by the time we get the data and
validate, more blocks have passed, and we'd be after horizon again.
So we request the txhashset for a more recent block than the one
at horizon.
The current value was 20, leaving only 20 min of slack, which isn't
enough for debug builds and isn't future-proof. Change to use
`0.9*horizon`, leaving about 2.5 hours.
* beginning to refactor keychain into wallet lib
* rustfmt
* more refactor of aggsig lib, simplify aggsig context manager, hold instance statically for now
* clean some warnings
* clean some warnings
* fix wallet send test a bit
* fix core tests, move wallet dependent tests into integration tests
* repair chain tests
* refactor/fix pool tests
* fix wallet tests, moved from keychain
* add wallet tests
Adds a `BufWrite` around each file that gets incrementally written
to in the MMR store main types. Should speed up a few operations
quite a bit, but particularly flushing the remove log. Saving
txhashsets on new blocks is now 10x to 20x faster, making full
block syncs a lot faster.
* block sums and reworked block validation
read and write block_sums
refactor validate on both block and txhashset
write block_sum on fast sync
we store the kernel_sum (need to account for the offset)
* block_sums
* rustfmt
* cleanup
* mods to speed up restore a bit
* mods to speed up restore a bit
* performance improvements to wallet restore and split large server queries into multiple
It looks like lockfile implementation did still suffer from a race
condition. Only when creating the file with O_EXCL, file creation fails
if the file does already exist. One could use O_EXCL, but Windows
might use another flag to achieve the same. Moreover, O_EXCL doesn't
work as expected if the files are accessed over NFS.
In contrast, mkdir() is atomic in every of the mentioned cases.
Aside from using a lockdirectory, this patch also backups the current
wallet.dat contents to wallet.bck in case writing a possibly hefty
amount of JSON to the new wallet.dat fails. It is hoped that at least
one of the .bck and .dat files has usable contents in case failure.
* wip BlockMarker struct, get rid of PMMRMetadata
* use rewind to init the txhashet correctly on startup, we do not need to track pos via metadata (we have block markers), we do not need to open the txhashset with specific pos (we have rewind)
* better logging on init
* keep rewinding and validating on init, to find a good block
* use validate_roots on chain init
* Test multi kernel deaggregation
* Add aggregate without cut_through and deaggregate function
* Add deaggregate function in pool and test
* Rustfmt
* Add deaggregate_and_add_to_memory_pool
* Deaggregate regular multi kernel transaction by default
* Rustfmt
* Add error type faileddeaggregation
* Add find candidates function
* Rustfmt
* Use intersection of sets instead of for comparisons
* Rustfmt
* Removed unnecessary if
* Stricter verification with is_subset
* Rustfmt
`Async<Discard>` means "drain that will send each logging
record to an async thread, that will discard it". This means
logging record is sent to another thread for no reason.
