| 16:06 | The log index and the file-history index check their contents in 4 KiB blocks as a call reads them, behind a header and block table checked at open, so an open no longer checksums whole files; a damaged block is repaired from the log, and a log that cannot be rescanned fails as an unreadable store; the file index gains a path table so a lookup bisects check-in: b377071cb2 user: dmestas tags: trunk | |
| 13:22 | log for a path reads each sub-manifest node through the walk's plaintext cache and parses only the line that decides the descent, so a one-shot log of 20 versions on a 42k-file tree store costs about 3 ms instead of 11 check-in: 5aea2fedb9 user: dmestas tags: trunk | |
| 12:29 | A diff between two check-ins walks both trees together and skips every sub-manifest both share by hash, so a one-file diff on a 42k-file tree store costs about 3 ms instead of 83; used by diff, the daemon's diff and timeline -v check-in: 3d9d26ef9b user: dmestas tags: trunk | |
