emitted exactly once in the required order, regardless of files_to_index or
all_chunks being empty. Preserve the existing file and chunk counts, and keep
the zero-count embedding behavior for empty input while removing the inverted
duplicated branches.
- Around line 583-587: Batch the file-hash updates in the indexing flow instead
of calling set_file_hash once per prepared file; add a batch hash method on the
metadata store that performs all writes within one explicit transaction, then
invoke it once with prepared_files while preserving the existing error context.
- Around line 448-460: Update the file preparation flow in the branch checking
FileIndexStatus::Indexed to collect modified ParseError files separately instead
of discarding them. For those failures, remove their prior parse/chunk data,
persist the ParseError state and new hash without counting them as successful
files, while leaving provider failures deferred.

Also assert that the file hash is unchanged.
The test proves parse data survives an embedding failure. It does not prove the update is retryable. If set_file_hash ran for types.ts, the next update would classify the file as unchanged and the new content would never be indexed. One extra assertion covers that property.

Avoid duplicating file contents in memory.
modified and added already own their (path, content, hash) tuples. Line 392 and Line 397 clone them into files_to_index, so every file content exists twice until the function returns. current_files still holds a third copy. Consume the source vectors instead.
Note the same pattern at Line 463: all_chunks clones every chunk of every prepared file, so chunk content is held twice until publication. You can borrow the chunks for embedding and insertion, because insert_chunks and Bm25Index::insert_chunks take slices and prepared_files stays alive until the end of the publication block.
♻️ Proposed change for the file-content copies

- .map(|(path, content, hash)| (path, content, hash, true))

Persist parse failures for modified files.
When a modified file returns FileIndexStatus::ParseError, the code discards it before publication. Old chunks remain searchable, the old Indexed state and chunk_count remain, and the old hash causes the file to be retried as modified on every update.
Collect failed files separately. Remove old parse and chunk data for modified failures, persist their ParseError states, and update their hashes. Do not count them as successful files. Keep provider failures deferred.

Flatten the duplicated progress branches.
ParsingDone and EmbeddingDone { count: 0 } are emitted from three places with two inverted files_to_index.is_empty() checks. The observable event sequence is the same in all cases: one ParsingDone, then one EmbeddingDone. Emit each event once.

Batch the file-hash writes. set_file_hash runs outside an explicit transaction, so this loop performs one autocommit transaction per prepared file. Add a batch hash method and call it once for prepared_files.

…s post-cancel progress When an embedding batch fails at the same moment cancellation fires, report the provider error instead of masking it with 'operation cancelled', matching the biased select in cancel_on_signal. Skip progress callbacks once the token is cancelled so cancellation returns without reporting further progress, as documented.

Rebased onto master after VeraTools#60 restructured the update path. VeraTools#60 stages parsed files in `PreparedFile` and defers every destructive write until embedding has succeeded, so a read or provider failure leaves the previous index intact. The original version of this change wrote parse artifacts immediately after parsing, which would have reopened that window. Verified: moving the batched write back to just after parsing fails VeraTools#60's own `update_embedding_failure_preserves_existing_parse_data` (0 references surviving instead of 1). So the parallelism is applied inside that structure rather than around it. Parsing runs under rayon and produces `PreparedFile` values; the writes stay at the same point in the sequence, only batched: - tree-sitter parsing is CPU-bound and now runs in parallel, with `collect` preserving `files_to_index` order so `prepared_files` is ordered identically to the sequential path - `chunk_file_for_update` returns its parse error instead of pushing into a shared `Vec`, which is what let it move under rayon - per-file `insert_references`/`insert_type_relations` become one `insert_parse_artifacts_batch`, and per-file `set_file_hash` becomes one `set_file_hashes_batch` - freshness hashing parallelized, and vector search batch-fetches chunk metadata instead of one query per candidate Both of VeraTools#60's atomicity regression tests still pass.

…ds (#69) (#73) * perf(indexing): parallelize the update path and batch metadata writes Rebased onto master after #60 restructured the update path. write until embedding has succeeded, so a read or provider failure leaves the previous index intact. The original version of this change wrote parse artifacts immediately after parsing, which would have reopened that window. Verified: moving the batched write back to just after parsing fails #60's own `update_embedding_failure_preserves_existing_parse_data` (0 references surviving instead of 1). So the parallelism is applied inside that structure rather than around it. Parsing runs under rayon and produces `PreparedFile` values; the writes stay at the same point in the sequence, only batched: - tree-sitter parsing is CPU-bound and now runs in parallel, with `collect` preserving `files_to_index` order so `prepared_files` is ordered identically to the sequential path - `chunk_file_for_update` returns its parse error instead of pushing into a shared `Vec`, which is what let it move under rayon - per-file `insert_references`/`insert_type_relations` become one `insert_parse_artifacts_batch`, and per-file `set_file_hash` becomes one `set_file_hashes_batch` - freshness hashing parallelized, and vector search batch-fetches chunk metadata instead of one query per candidate Both of #60's atomicity regression tests still pass. * test(storage): cover the batch metadata APIs directly `set_file_hashes_batch`, `insert_parse_artifacts_batch` and `get_chunks_by_ids` only had indirect coverage through their callers. Adds multi-row persistence, replace-on-repeat, the empty-input early return, and the partial-result case the vector search path relies on. Also collapses the two fixture guards in the ordering test into one: the chunks are inserted in id order, so insertion order and primary-key order are the same sequence and the second assertion could never fail independently. * test(storage): assert what the batch metadata tests claim to check Both tests passed without verifying the behaviour named in the test itself. insert_parse_artifacts_batch_persists_both_kinds_across_files asserted only that find_callers("helper") returned 2 rows. That count holds just as well if both references were stored under a single file path, so the "across files" part went unverified: a batch that ignored the second file's path and attributed every reference to the first would have stayed green. It now collects the returned CallerRef file paths, sorts them, and requires exactly src/lib.py and src/main.rs. set_file_hashes_batch_persists_every_row_and_replaces_on_repeat re-checked only src/main.rs after the second batch wrote that one key. A batch that cleared the table before inserting, or otherwise dropped rows it was not given, still produced hash-c for src/main.rs and passed. It now also asserts src/lib.py is untouched at hash-b, so a partial write that takes out unrelated rows fails. Both new assertions were confirmed to fail against a deliberately broken variant before being kept. * perf(indexing): preserve cancellation and avoid batch copies --------- Co-authored-by: lemon07r <lemon07r@gmail.com>

This follow-up fixes the review findings from #29 that still reproduce on current
master.Review the cancellation boundary closely. The public token keeps its clone-shared, permanent signal but now wraps Tokio's cancellation token instead of an atomic flag. One token covers the full indexing run. Cancelling it drops active provider futures, stops batch splitting and retries, and blocks artifact publication after the final progress callback. Embedding capacity still comes from
bounded_parallelism; the configured batch size, request concurrency, and maximum in-flight inputs do not change.The incremental update publication boundary also changed. Reads, parsing, and embedding now finish before stored data changes. A file found during discovery is not treated as deleted if a later read fails. Failed preparation keeps the prior hash, chunks, vectors, BM25 entries, references, and type relations. The write phase stays synchronous and uses the existing per-store replacement operations. This PR does not add a cross-store transaction.
The remaining fixes are independent:
Current
masterdoes not contain the reported detached signal task.cancel_on_signalpolls both futures inline and does not spawn a listener.Validation:
cargo test -q -p vera-core -p vera-clicargo fmt --all -- --checkcargo clippy -p vera-core -p vera-cli --all-targets -- -D warningsgit diff --checkClippy needed allowances for two unrelated warnings already present before this branch.
Need help on this PR? Tag
@codesmith-botwith what you need. Autofix is disabled.Summary by cubic
Fixes indexing regressions by making cancellation cooperative across the pipeline and publishing updates only after parsing and embedding succeed. Provider errors now take precedence over simultaneous cancellation, and progress events stop once cancelled.
