2256-2257: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winControl the retry timers in this test.
The three real one-second waits make every run slower. Under a delayed CI event loop, the test can time out even when the retry logic works. Start the sync, wait until all three retry sleeps are scheduled, then advance fake timers asynchronously. Restore real timers after the test. Vitest supports this timer control. (vitest.dev)
Based on learnings, automated tests should control timers instead of relying on real time.

Sol Ultra:
-
[P2] Ctrl+C still allows new cloud writes. sync.ts:960 stops workers from taking another project, but active workers continue. I cancelled project A’s prompt while B was waiting on its export; B subsequently started an import. Cancellation also waits for these workers, then skips the final manifest save. Propagate cancellation into active project work and check it before starting mutations.
-
[P2] Warnings still print over conflict prompts. sync.ts:902 buffers completion messages, but other workers call
warn()anddebug()directly. I reproduced an--all-fileswarning appearing while another project’s prompt was open. All background terminal output needs the same buffering.
Other:
- Timing-based concurrency tests: sync.test.ts:1674 uses 20/30/50 ms sleeps. The prompt test can pass without another project completing during the prompt. Explicit promise gates would prove the intended interleaving.
- Misleading assertion: sync.test.ts:1819 counts manifest-save calls accumulated from earlier tests/setup. Clear the mock before the operation.
- Unnecessary worker allocation: sync.ts:968 creates the requested number of workers even for an empty workspace. Clamp it to the project count.

Does this simply check that we are dealing with a positive integer? AI might have gone a bit too far overcomplicating this part. 😅

Yes. I left it there, as there was no harm in keeping this test. Lemme clean it up, though.

Yes, it only checks for a positive integer. Simplified in 0fdbd34, and I dropped its tests in af3e495.
I think AGENTS.md triggered this. It tells agents to "Create comprehensive tests for all new features" and to "Test edge cases, error handling, and special characters", and to "Prefer type safety over convenience".
Following that, a four-line option parser got a regex, a safe-integer check, and two sets of tests. It might be worth softening those lines so small helpers don't get the same treatment. I'll take that separately.
Though to me, this is not an issue.

- Around line 330-336: Update writeProjectNotebooks and writeFileEnsuringDir to
check cancellation immediately before each filesystem mutation and again after
awaited operations that precede another mutation. Pass ctx to
writeFileEnsuringDir and use it to guard mkdir and writeFile, case-variant
renames, and notebook removals; update all helper call sites accordingly.
- Around line 704-710: In the replacement flow, re-check cancellation after
`persistManifest()` completes and immediately before `deleteProjectFile()` so
cancellation during the await cannot delete the existing cloud file. Do not add
a cancellation check between `deleteProjectFile()` and `uploadProjectFile()`;

The sync client had no 429 handling: a rate-limited list call aborted the whole run and a rate-limited export failed the project. Every sync request now retries a 429 after Retry-After (falling back to RateLimit-Reset, then capped exponential backoff), and retries 5xx, timeouts, and network errors for GET and DELETE. POSTs (import, file upload) are not retried on those, since the server may already have applied them. The transient-error check and backoff are extracted from cloud-runs into a shared retry module.

`deepnote sync` exported every project one after another, so a 2,333-project workspace took about 10 minutes. Projects now sync through a bounded worker pool (`--concurrency <n>`, default 8), with the rate-limit retries from the previous commit keeping parallel exports inside the workspace's API limit. - Directory moves for renamed projects still run first, one at a time, so a move can never race another project's writes. - With `--on-conflict ask`, a project that needs an answer (both-sides conflict, push rejected with 409, empty-directory push with --delete-missing-notebooks, diverged working files) pauses; its question is asked after every other project has finished, one prompt at a time. `--concurrency 1` keeps prompting inline. Ctrl+C still aborts the run, and the manifest is saved before the first deferred prompt. - Manifest saves go through a single queue. - Outcomes are sorted by path so `-o json` and the summary stay stable.

"Suspendable" is not in the spell-check dictionary that the pre-push hook runs. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01FpPTUYw5TTkHLEVPtQcjRQ
A timed-out GET was retried five times, each attempt waiting out the full request timeout, so an always-slow export failed after about 12 minutes instead of 2 (a file download after about an hour). Timeouts are now retried at most once (`maxTimeoutRetries`), still only for GET and DELETE. Every TypeError also counted as transient, so a caller mistake such as an invalid base URL slept through 31 s of backoff before failing the same way. Only TypeErrors whose message or cause code identifies a network failure are retried now. cloud-runs keeps its broader predicate.

Two ways the move phase could lose an unpushed local edit: - Moves ran in destination-path order, so a project moving into `Foo/Y` could land inside `Foo` just before another project renamed `Foo` away, carrying the first project with it. Its sync then found nothing locally and pulled a fresh copy. A move now waits until no other pending move still has to vacate a path overlapping its destination; a cycle (two projects swapping paths) is broken by parking one directory under a temporary sibling name. - Moves were only written to the manifest at the end of the run. An interrupted run left the renamed directory on disk with the manifest still pointing at the old path, and the next run treated it as untracked, where `--on-conflict override` overwrote the edit. The manifest is now saved right after the moves, before any project syncs.

When a push 409 is answered with override, the question may have waited for the rest of the workspace to sync. The forced import used the notebook files read at the start of the run, so an edit made while waiting was overwritten by the post-push export. The files are now re-read right before the forced import; an empty directory under --delete-missing-notebooks or a removed directory skips instead. Also covers a project that asks two questions in turn (push 409, then diverged working files).

A 429 wait can last up to a minute, and was only visible with --debug, so a throttled sync looked stuck. Sync now prints "Rate limited by the Deepnote API; waiting N s…" on the normal progress channel, once per wait rather than once per parallel request, and never with -o json. Retries of server errors, timeouts, and network failures stay debug-only.

More parallel requests only reach the API rate limit sooner, and with --all-files each worker may buffer a file of up to 100 MiB, so an unbounded value risked large memory use for no throughput. Values above 32 are rejected as invalid usage (exit code 2); --help states the cap, the retry limits, and the memory note.

A deferred "skip" on working-file conflicts used the upload plan made before the question waited. A file that was only modified locally when the plan was made, but edited in Deepnote while the question waited, was then deleted and re-uploaded over the colleague's edit. Uploads are now re-planned on fresh local files and a fresh inventory after any deferred answer. A file that conflicts in the fresh plan, and was not approved for overwrite as shown, is kept and counted as skipped.

The manifest save after each directory move could throw and abort the
whole run. A failed save now gives only the moved project an `error`
outcome ("moved to <dir> but the manifest could not be saved: …"). Its
record keeps the new directory in memory, the other projects keep
syncing, and the end-of-run save still runs.

The rate-limit notice test now gives up after 200 fake seconds instead of spinning forever if the sync never finishes. It restores real timers in a finally block, and its early bail-out does not leave the sync promise rejected but unhandled. The swap test's name now says it covers two non-empty directories, which is all it asserts.

A deferred answer is acted on only after the project is re-read: an overwrite runs only if there is still something to overwrite, and working-file uploads are re-planned whichever way the user answers.

Once a project had one answer on record, its re-run answered any question of a different kind with "skip". With --concurrency above 1, an emptied directory pushed with --delete-missing-notebooks whose import then 409'd could never be pushed: the user confirmed the empty push, and the 409 question was skipped every time. The re-run now asks the follow-up question, as --concurrency 1 does. A question kind that already has an answer is still never asked again, and a recorded push-409 override still force-pushes the fresh files when the project classifies as a conflict. Also corrects the moveTrackedProjectDirs doc comment: a project whose manifest save failed after its rename has been moved, and its record is updated in memory.

A notebook-level skip is not re-checked, since it changes nothing. Only overrides re-read the project, and working-file uploads are re-planned after either answer. The skill reference now matches the README and docs. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01FpPTUYw5TTkHLEVPtQcjRQ
…e timers The "says once when parallel requests wait on the same rate limit" test failed on Node 22, 25, and .nvmrc in CI. Its fake setTimeout and Date did not reliably let the real fs I/O inside syncWorkspace progress, and the notice's once-per-wait check compared wall-clock times. The notice now uses a counter of requests currently waiting on a 429. It prints only when the count goes from 0 to 1, so nothing depends on the clock. To know when a wait ends, the retry `sleep` option (already in RetryOptions) now also receives the retry's details, and the CLI passes a sleep that tracks the count. The test runs on real timers: the three 429s are delivered together with Retry-After: 1, so their waits overlap deterministically, and it still asserts that all three were rate limited, that exactly one notice was printed, and that the sync succeeds.

… edits A deferred both-sides conflict answered with "overwrite the local files with the cloud version" re-ran the project on fresh data. If the cloud edit had been undone while the question waited, the fresh export matched the manifest, so the project classified as a push and uploaded the local changes the user had chosen to discard. On main the answer applied at once as a pull. A recorded both-changed override now pulls the fresh export whenever the fresh data classifies as a push or a conflict, mirroring the push-409 guard. Noop and pull still take their normal paths. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01FpPTUYw5TTkHLEVPtQcjRQ
…fore The symbolic-link ancestor check for every project's planned directory ran in the prepare loop, before any directory move. A new project planned under a path that ran through a renamed project's notebook file (say `Foo/main.deepnote/Child`, while `Foo` is about to move to `Alpha`) hit ENOTDIR and failed until the next sync. On main each project was checked and moved in path order, so the move had already happened. The check now runs when each project syncs, after the move phase. Each move checks its own destination right before renaming into it.

…imal one Reset the branch's sync changes to main and re-implement concurrency in its smallest form: - @deepnote/cloud sync client retries HTTP 429 only, up to 5 times, waiting per Retry-After, then RateLimit-Reset, then exponential backoff, capped at 60 s. 5xx, network errors and timeouts behave as on main. The retry.ts module and the cloud-runs refactor are gone. - deepnote sync runs main's unchanged per-project sync on a small inline worker pool (--concurrency, 1-32, default 8). A run that moves a tracked project directory stays sequential. Conflict prompts open one at a time and hold progress lines while open; a Ctrl+C stops new projects and further prompts. Manifest saves are serialized and outcomes are sorted by path. Rate-limit waits are logged with --debug.

Only progress lines were held back, so another project's warn() and debug() output was still drawn over an open prompt. Route all output from per-project work through the same buffer. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A Ctrl+C only kept workers from taking another project; those already running went on, so a project waiting on its export could still start an import. Mark the run cancelled when the prompt exits and check it before every write to disk or to Deepnote. Save the manifest before rethrowing so the projects that finished stay recorded. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The concurrency tests waited on 20, 30, and 50 ms timers, so a slow run could fail them and the prompt test could pass without any project finishing while the prompt was open. Count the projects in progress when each export starts, hold requests on explicit promises, and let the prompt stay open until the other projects have finished.

Problem
deepnote syncexports projects one at a time, so run time grows with workspace size. On a workspace with a few thousand projects a run takes about 10 minutes, even when nothing changed.The sync client also ignored HTTP 429. A rate-limited list call aborted the run, and a rate-limited export marked the project as
error. Running exports in parallel would fail projects as soon as the API rate limit kicks in.Closes #536
What changed
deepnote syncruns projects in parallel, 8 at a time by default.--concurrency <n>changes that. Each worker runs the existing per-project sync.Retry-After, thenRateLimit-Reset, then exponential backoff, at most 60 s per wait. Other failures behave as before.projectslist in-o jsonis sorted by path.--helpcover--concurrencyand the retry.Throughput is still capped by the workspace's API rate limit.
