- plain --delete with no timing flag now selects delete-during (progressive
deletion, matching rsync and avoiding the full old+new tree peak)
- new long-only FastSync --delete-commit restores the old atomic behavior
(delete only after the whole transfer succeeds); timing-identical to
--delete-after, implemented via the same wire bool
- timing flags are mutually exclusive; --delete-commit conflicts with other
timings; --delete-before/--delete-during rows reworded per Phase-0 probes
- CHANGELOG migration note; tally unchanged 116/14/27
- -n/--delete sends the same protected/size-skipped/scope as a real run, so
the read-only would-delete walk no longer over-reports (row -> caveat)
- --delete-delay charges --max-delete on actual removals and recursively
re-scans a refilled deferred directory at commit; independent deferred cap
- --info=name emits the leading ./ root line and name2 'is uptodate' lines
- differential tests promoted from residual pins to rsync parity assertions
- --delete-delay: state that the reported count advances on actual removal
while --max-delete is charged at plan/snapshot time (defer_add/planned).
A new differential shows rsync instead charges on actual removals and
recursively removes a queued directory, so the row moves to Caveat
(matrix 111/13/33) and the residual is pinned by tests.
- Add a deterministic unit test (plan-time budget charge), a FastSync
integration test (byte-barrier refill + --max-delete), and an rsync
differential for a refilled deferred directory.
- Soften the --fuzzy summary: the tree is byte-exact by design, so it is
pinned by the threshold suite, not a byte-level differential.
- README: describe what -m parity actually selects; fix the allowlist
example to the real max_delete entry.
- xdist-safe delete-timing fixture names (timing and --threads mode).
- Renumber the duplicate HANDOFF item 9 to 10; add the missing final
newline to test_checksum.c.
- Expose ignore_errors_allows_delete and unit-test the deletion gate
without a privileged source directory; update the stale deleted-count
doc comment.
No production behavior changes.
- Initialize PipelineContextSender.delete_suppressed=false: an uninitialized
true silently skipped the --delete keep-set manifest under -m/--threads,
so destination extras were never removed.
- Allocate/install the receiver deleted-path observer only when
report_deletes is set (--info=del / -i / --out-format under --delete), cap
the retained list at MAX_MANIFEST_ENTRIES, and free already-created lists
on the receiver-pipeline create failure path.
- Validate report_deletes/report_stats/report_dest_info on receive.
- Correct stale comments (config.h report_deletes, delete_plan.h deleted
count, multiprocessing.h stats locking, utils.h observer placement).
- Tests: sender delete_suppressed init, report_deletes gating (unit), and
-m/--delete default delete-after keep-set removal (integration).
- --delete-delay: count/track only entries actually removed; a directory
refilled before commit (ENOTEMPTY) no longer inflates Number of deleted
files or the --max-delete budget (unit + integration + rsync differential).
- --stats: per-type Number of files breakdown; only stored regular files
count as transferred; transferred/literal byte totals and Total file size
(symlink target lengths) now match rsync for whole-file transfers.
- --progress: print the leading ./ root line and include the root entry in
the to-chk denominator (single-file output byte-identical to rsync).
- --out-format %C: use the selected transfer checksum and render every
algorithm exactly like rsync; checksum_digest_file gains md4/sha1/none.
Reclassify --out-format to Divergent (protocol-specific %b/delta-%c).
- Docs: RSYNC_COMPAT tally 107/25/24, HANDOFF update. No wire change.
- Output parity: add `File list size` to the strict --stats differential and
document the row-#3 residual with test_stats_file_count_breakdown_residual
(rsync's `Number of files`/`Number of created files` type breakdown is not
reproducible from what the sender knows: no directory accounting and no
per-entry destination-created state). The row stays a caveat.
- Add --threads variants for the --stats and --progress/-P differentials.
The `-n --delete --threads` variant is a documented xfail: the threaded
dry-run path does not consume the receiver's STATUS_STATS delete list yet.
- Replace the 0.2s sleep flake in the delete-timing proxy with a socket
barrier: the hook now fires only after the server sends a reply (proving it
processed the preceding per-directory delete plan), using --incremental +
--ignore-times to guarantee a mid-transfer handshake reply.
- Compare --delete-during/--delete-delay final state against rsync 3.4.1.
- Force a mid-transfer failure through a byte-slicing proxy: --delete-during has
removed the processed directory's extra, --delete-delay has not.
- Create a destination entry while the transfer is in flight: it survives
--delete-delay's snapshot but is removed by --delete-after's fresh end scan.
- Cover the --delete-delay type-conflict case now matching rsync.
