adds a line when no copyright for Dogecoin Core Developers exists
but the file has been edited by us, to the last year found in git
log, or extends the year range on an existing line when a file
has been modified since the year previously listed.
Excludes subtrees.
- The last-timestamp-encountered variable wasn’t being used properly. Rewrite code to properly allow for new blockchain files to be written when split by month.
- Properly set a blockchain file’s access and modify times.
- Add a “debug output” option to quiet certain output that might not always be desirable.
- Update the README.
- Add a space after the fixed string prepended to file names when input or
output file changes
- Clarify the error message when the genesis block is not found in the
hash list (...why do we have this at all?)
Make it possible to read blocks in any order. This will be required
after headers-first (#4468), so should be merged before that.
- Read block header. For expected blocks, continue, else skip.
- For in-order blocks: copy block contents directly. Write prior
out-of-order blocks if this connects a consecutive span.
- For out-of-order blocks, store extents of block data for later
retrieval. Cache out-of-order blocks in memory up to 100MB
(configurable).
This was typically ensured implicitly by virtue of normal bitcoind
operation. Adding an explicit check provides a stronger guarantee, and
it is cheap to add.
Break into two steps:
* Generate hash list
* Build data file(s) from local bitcoind blocks/ directory.
This supports building one large bootstrap.dat, or multiple
smaller blocks/blkNNNNN.dat files.
