fix(flare-insights): speed up sync and dashboard, add sync progress - #640
Conversation
sync was a full re-parse of every session file on every run with no progress output, and each session upsert committed its own transaction. The dashboard reopened + re-migrated the SQLite DB on every request, recomputed full analytics on every 5s poll, and just dumped raw JSON into a <pre> tag. - store: batch session upserts into one transaction (upsert_sessions_batch) - ingest: skip re-parsing session files unchanged since the last sync, tracked via a new ingest_file_cursors table (mtime+size per file) - sync: print live per-source file-scan progress instead of running silent - api: share one long-lived connection instead of reopening per request, split into separate reader/writer connections so the WAL DB's background resync doesn't serialize behind request handling, cache /api/stats, and replace the dashboard's raw JSON dump with a real stat-tile + sessions-table UI with a longer client poll interval Measured on this machine's real session history: sync went from ~85s to ~9s on a warm run (unchanged claude/codex files skipped); /api/stats went from ~9s per poll to ~0.2s while cached.

Advance the cursor only after a successful parse.
parse_codex_jsonl can return None, but Line 53 still records the file cursor. The next sync then skips that unchanged file. A transient read or parse failure can therefore hide its session data until the file changes.
Move the cursor insertion into the Some((s, turns, tools)) branch. This matches the IngestBundle.file_cursors contract.

Commit file cursors only after complete ingestion succeeds.
Line 127 records a cursor even when any earlier batch upsert failed. Line 62 adds a cursor when parse_claude_jsonl returns None, including failed reads that read_jsonl_sessions converts to an empty result. The next sync then skips the unchanged file while its data is absent or partial.
Make parsing distinguish a readable empty file from a failed parse. Persist all bundle entities and their cursors in one transaction. Advance the cursor only after that transaction commits.

Commit file data and file cursors atomically.
crates/flare-insights/src/ingest/watcher.rs ignores failures from the session, turn, tool-call, file-event, and subagent batch writes, then calls this method. If any data batch fails but this transaction commits, the persisted cursor makes the next scan skip that file. The failed records then remain absent until the source file changes or the cursor is removed.
Use one transaction for the complete ingest bundle, including its cursor updates. At minimum, propagate each data-write error and do not advance cursors after any failed write.

Do not persist cursors after a failed data write.
Line 178 and the other batch writes discard their Result values. If any data write fails, Line 191-192 can still persist ingest_file_cursors. The next incremental scan can skip the unchanged files, so the failed data is not retried while the CLI reports success.
Handle every batch error, stop the source sync on failure, and persist cursors only after all data writes succeed.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Byte slicing of chunk content panics on multi-byte characters. Both snippet builders cut the chunk body at byte offset 200 with &content[..200]. str indexing requires a char boundary, so any chunk whose 200th byte falls inside a multi-byte character panics. Markdown chunks routinely contain such characters, for example — or CJK text, so a single stored document can abort every vector search for its project.

Fix parameter binding for combined glob and metadata filters. When path_glob and a non-empty meta_filter are set, doc_search_filtered generates ?10 and higher metadata placeholders but binds only six or four values. rusqlite returns InvalidParameterCount, so the search fails. Build placeholders and bindings from one sequential list, then use params_from_iter.

Fix the self-deadlock in doc_search_filtered.
Line 566 acquires the connection guard. That guard is a parking_lot::MutexGuard, so it lives until the function returns. Lines 652 and 655 call self.doc_search and self.doc_get_meta, and line 665 calls self.doc_search. Each of those calls self.conn() again. parking_lot::Mutex is not reentrant, so the thread blocks forever.
Two reachable paths hang:
meta_filterwith more than one entry and nopath_glob(the multi-filter fallback).src/mcp_server/search.rscallsdoc_search_filteredwhenevermetais present.meta_filterandpath_globbothNone, which falls through to line 665.
The same non-reentrancy is already documented in doc_delete at line 1007.
Scope the guard so it is released before any self.* call.
🔒 Proposed fix: scope the connection guard
- let conn = self.conn();
- let fts_query = flare_search_kit::fts_phrase_query(query);
+ let fts_query = flare_search_kit::fts_phrase_query(query);Then acquire the guard only inside the branches that run SQL directly, for example:
if let Some(filters) = meta_filter {
if filters.len() == 1 {
let conn = self.conn();
// prepare + query_map here, guard drops at the end of this block
...
}
// multi-filter fallback: no guard held, self.doc_search / self.doc_get_meta are safe

doc_delete leaves store_chunk_vec0 rows behind.
Line 1031 removes store_chunk_vec rows and line 1032 removes the chunk rows. When the vector feature is enabled, store_chunk_vec0 is keyed on store_doc_chunks.rowid, and nothing deletes those rows here. sync_chunks (line 144) does delete them, so the two paths disagree.
SQLite reuses the highest rowid after the last rows are deleted. New chunks can therefore take a rowid that still carries a stale embedding, and chunk_vec_search_ann joins store_chunk_vec0 to store_doc_chunks on that rowid. The ANN result then reports a live document with another document's embedding distance.
Delete the vec0 rows before the chunk rows, as sync_chunks does.

For fastembed 6.0.0, can TextEmbedding::try_new, TextRerank::try_new, or SparseTextEmbedding::try_new download or initialize model files when the local cache is missing, and can this delay failure while offline?
💡 Result:
For fastembed 6.0.0, the methods TextEmbedding::try_new, TextRerank::try_new, and SparseTextEmbedding::try_new are designed to automatically download model files from a remote source (typically Hugging Face) upon their first use if the required files are missing from the local cache [1][2][3]. Because these methods perform this network-dependent download attempt as part of the initialization process, they will fail if the local cache is empty and the system is offline [1][2][4]. The library returns a specific error (e.g., Error::Retrieval) when it cannot fetch the required files [4]. To avoid this failure when working in an offline environment, you must ensure the models are already present in the cache directory before calling these methods [1][5]. Alternatively, you can use the *_from_user_defined or *_from_path methods (such as TextEmbedding::try_new_from_user_defined) which allow you to load models directly from local files provided by the user, bypassing the automatic remote download behavior [1][6][4].

fastembed 6.0.2 source TextEmbedding::try_new TextRerank::try_new SparseTextEmbedding::try_new hf-hub download model files
💡 Result:
In fastembed 6.0.2, the try_new methods for TextEmbedding, TextRerank, and SparseTextEmbedding serve as the primary entry points for initializing models when using the hf-hub feature [1][2][3]. These methods automatically handle the download and retrieval of necessary model files—including the ONNX model and tokenizer configuration—from the Hugging Face Hub based on the provided configuration options [4][5]. Key details regarding these methods: 1. Initialization Methods: - TextEmbedding::try_new(options: TextInitOptions): Initializes a dense text embedding model [1][6]. - TextRerank::try_new(options: RerankInitOptions): Initializes a reranking model [2][7]. - SparseTextEmbedding::try_new(options: SparseInitOptions): Initializes a sparse text embedding model (e.g., SPLADE) [3][8]. 2. HF-Hub Integration: These methods are gated behind the hf-hub crate feature [1][2][3]. When called, they invoke internal logic that leverages the huggingface-hub client to retrieve model artifacts into a local cache directory [4][9][5]. By default, this uses the directory specified by HF_HOME or a default cache path (which can be configured via with_cache_dir in the respective InitOptions) [9]. 3. Model File Downloading: The internal implementation performs the following steps: - Retrieves the model repository from the Hugging Face Hub [4][5]. - Downloads the required model weight files and additional metadata (such as pooling configurations or tokenizer files) defined in the model's manifest [4][5]. - Configures the ONNX Runtime session and tokenizer using the downloaded files [4][5]. 4. Custom Models: If you have local model files rather than fetching from the Hub, you can use the *_from_user_defined variants (e.g., TextEmbedding::try_new_from_user_defined) to initialize models from specific file paths without requiring the hf-hub integration [1][4][2][5].

Record failed model initialization with bounded retry backoff.
fastembed 6.0.2 can download missing model files during each try_new call. These error branches leave their Mutex<Option<_>> slots as None, so later calls retry initialization while holding the mutex. When the cache is missing or the host is offline, repeated calls can delay the BM25 fallback. Store a failed state and retry only after a bounded backoff or an explicit reset.
