Operator-and-analyst quality bundle: a security fix for the optional
Telegram bot, two CLI gaps closed, and three rounds of UX polish on
`agnes diagnose` and `agnes pull` so non-TTY consumers (CI runners,
Claude Code SessionStart hooks, sub-agent watchdogs) get readable,
actionable signal.
- Pairing-code RNG: random.choices -> secrets.choice (CSPRNG).
- Telegram script runner: refuse out-of-shape usernames before sudo -u.
CLAUDE.md.bak.<ISO-timestamp> before regenerating.
- agnes admin unregister-table <id> -> DELETE /api/admin/registry/{id}
- agnes admin update-table <id> --field=value ... -> PUT /api/admin/registry/{id}
response but never promotes the headline. BQ billing-equals-data check
downgraded warning -> info.
default (5 s / 1 MiB vs 30 s / 10%) so sub-agent watchdogs don't kill
the pull as a hung process. New env knobs:
AGNES_PULL_PROGRESS_INTERVAL_{SECONDS,BYTES}.
--include-schema (or ?include=schema) to opt back in.
Tests: 120 passed across the touched modules, including new tests for
each fix. Pre-existing failures on main (DB migration v1->v9, binary
rename) are unrelated and not introduced here.
Two improvements to `agnes pull` progress reporting:
1. **Aggregated per-file progress across chunked downloads**: the
existing Rich progress bar already used one task per file, but the
chunked-download contract (one file = N parallel chunk callbacks
summing to file size) meant we needed to verify that all chunk
threads advance the same task. They do — the per-file callback is
constructed once per tid and routes every chunk's byte delta to the
same task / textual entry, so the bar shows one aggregated bytes-
downloaded total rather than N separate sub-bars.
2. **Textual fallback for non-TTY stderr**: when stderr is not a
terminal (SessionStart hook, CI runner, Docker log capture), Rich
either suppresses output (silent multi-minute pull on a 5 GB
parquet) or emits raw control sequences. The new `_TextualProgress`
helper instead emits one plain-text line per file at most every
10%-of-total-bytes or 30 s, plus a final `100% done` line per file.
Format: `[N/T files] <tid>: 25% (16 MB / 66 MB) at 1.5 MB/s`.
The TTY path is unchanged. Detection uses `sys.stderr.isatty()` —
`show_progress=True` flips into the textual fallback when that returns
False. `show_progress=False` (the SessionStart hook) still emits no
progress text in either mode.
Three first-try-failure-surface fixes from Pavel's #185 trace + the
template guidance question, all under PR #188's umbrella so they land
together with the file_server / parallel pull / Tier 1 work.
1. CLI clean-error wrapper — new AgnesTransportError raised by the
api_*/stream_download helpers when httpx times out / drops /
refuses, plus a top-level Typer wrapper (cli/main.py) that prints
one-line "Error: …" + actionable hint and exits non-zero. Full
traceback goes to ~/.config/agnes/last-error.log for support
forwarding. Unhandled Exceptions are caught at the same boundary
so no Python traceback ever leaks to the analyst's terminal.
Pavel's #185 Phase 3B: a 30-frame httpx traceback from a slow BQ
--remote query made it look like a CLI bug. Now: clean message +
hint pointing at `agnes snapshot create` / partition-column
guidance.
Entry point in pyproject.toml flipped from `cli.main:app` →
`cli.main:_run_with_clean_errors` so the wrapper actually runs
under the installed `agnes` binary.
2. agnes init / agnes pull --skip-materialize + progress bar.
--skip-materialize omits query_mode='materialized' rows from the
download set so a first init doesn't spend 44 minutes silently
pulling a single 6 GB parquet (Pavel's #185 Phase 1). Rich-driven
per-file progress bar with label/bytes/rate/ETA renders to stderr
when not --quiet and not --json. Aggregates across the parallel
ThreadPoolExecutor workers added earlier in this PR.
3. config/claude_md_template.txt: explicit one-line snippet pointing
at `agnes catalog --json | jq '.tables[] | select(.id=="<id>")'`
for per-table descriptions + restated invariant: "the description
field on each catalog row is the authoritative business-rules
text — re-read live, never copy into this file." Resolves the
regression-or-feature debate between Pavel (wants annotations)
and the user feedback that landed in the prior commit (don't
embed table-specific content; tables change). Catalog command
stays the source of truth.
The download loop in cli/lib/pull.py was strictly serial — N tables took
Σ stream_download(t_i). With the Caddy file_server change in this PR,
the server can now sustain many parallel sendfile transfers without
blocking app workers, so the client-side serialization became the new
bottleneck.
Switch to ThreadPoolExecutor capped by AGNES_PULL_PARALLELISM (default 4,
set 1 to restore pre-PR serial). 4 matches typical home-broadband
saturation without over-subscribing the analyst's NIC. Drops to serial
when len(to_download) <= 1 to avoid executor overhead in the common
single-table case.
Per-table error semantics preserved via (tid, entry, err) tuple — a
failure on one parquet doesn't abort the rest of the batch.
Verified end-to-end against a dev VM with the new Caddy file_server
deployed: 2-table pull through agnes CLI works under the new concurrency.
Three Devin Review findings on PR #173 addressed in one commit since
they're in adjacent code paths:
1. cli/commands/init.py:99 (\u{1F534}): `agnes init --token NEW` ran
step 2 verify against the OLD on-disk token because `get_token()`
read `~/.config/agnes/token.json` before the env var, and
`_override_server_env` only set the env var. So `agnes init --force`
on a machine with a stale token.json failed 401 with a confusing
'token expired' even though the --token arg was valid.
Fix: ContextVar-based override in `cli.config._token_override`
checked by `get_token()` BEFORE the on-disk read.
`_with_token_override` context manager scopes the override.
`_override_server_env` now also sets the contextvar via
`_with_token_override(token)`, so both env var and contextvar
carry the override (env for back-compat with anything bypassing
get_token; contextvar is the authoritative source).
Async-safe (each task sees its own override) and leak-proof
(resets on context exit).
2 new tests: regression on stale-disk-token + scope leak guard.
2. cli/commands/status.py:43 (\u{1F7E1}): sessions_pending_upload only
checked legacy `<workspace>/user/sessions/` and always reported 0
in workspaces bootstrapped with `agnes init` (Claude Code writes
to `~/.claude/projects/`, not the legacy path). Same bug we fixed
for `agnes push` in 08e49591.
Fix: route through `cli.lib.claude_sessions.list_session_files()`
so status and push agree on what counts as a pending session.
3. connectors/bigquery/extractor.py:111 (\u{1F7E1}): docstring claimed
"a live holder still wins the second flock attempt" — incorrect on
Linux. After `unlink()` + `open()`, the new file is a new inode;
fcntl.flock keys per-inode, so the old holder's lock does NOT block
the new acquisition. In a genuine TTL-overrun scenario two writers
CAN race the parquet.tmp.
Fix: documentation only. Comment now honestly describes the
inode-recreation behavior, names the threading.Lock as the actual
in-process guard, and flags pid-gating as the next-iteration fix
if real corruption surfaces. The 24h default TTL is well above
typical COPY durations so the practical risk is low.
Tests: 17/17 across test_cli_init.py + test_lib_pull.py + the broader
regression set.
Pre-fix `agnes pull` decided what to download from sync_state hash
equality alone:
if server_hash != local_hash or tid not in local_tables or not server_hash:
to_download.append(tid)
If the recorded local hash matched server but the actual parquet had
been deleted from disk, the download was skipped. The next DuckDB
view rebuild then fails on a missing file. Repro: `rm
server/parquet/X.parquet && agnes pull` → 'Updated 0 tables', X
still missing.
Failure modes that produce hash-equal-but-file-missing:
- manual `rm` of a single parquet
- operator-side cleanup of `server/parquet/`
- two workspaces sharing one user's
`~/.config/agnes/sync_state.json` (TODO(workspace-scoped-sync-state)
in pull.py): one workspace writes its parquets, the other reads
sync_state and concludes 'I already have these'
- disk corruption / partial restore from backup
Fix: existence check runs alongside the hash compare. Missing file
forces a re-download regardless of hash equality. `parquet_dir` is
hoisted above the loop so the existence check is in scope when the
download set is built.
Tests: regression test for the hash-equal-but-missing-file case +
counterpart for the fast-path (hash-equal-and-file-present must
still skip).
