## Summary
- Both JS and Python SDKs now validate that the configured E2B API key
matches `e2b_` followed by 40 hex characters (mirroring the server-side
check in
[`infra/.../keys/key.go`](https://github.com/e2b-dev/infra/blob/main/packages/shared/pkg/keys/key.go#L66))
and throw `AuthenticationError` / `AuthenticationException` with an
example token (`e2b_0000…`) and a link to the API Keys dashboard tab.
- Validation runs inside `ApiClient` / `ApiClient.__init__` whenever an
API key is present, so callers get immediate, actionable feedback
instead of a generic 401 from the server.
- Added unit tests (`validateApiKey.test.ts`,
`test_validate_api_key.py`) and updated existing fixtures that used
placeholder keys like `'test-key'` / `'base-api-key'` to use the valid
format.

## Summary
- Add `spec/` to the pnpm workspace with a `package.json` that runs
`prettier --check`/`--write` on `openapi.yml` and `envd/envd.yaml`.
- The existing Lint workflow's recursive `pnpm run lint`/`pnpm run
format` now enforces YAML formatting automatically — no workflow changes
needed.
- Reformat `spec/openapi.yml` (two `$ref` quote-style changes) so the
new check passes.
## Test plan
- [ ] CI Lint workflow passes
- [ ] `pnpm --filter @e2b/spec run lint` succeeds locally

- Sync `spec/openapi.yml` from
[e2b-dev/infra@main](https://github.com/e2b-dev/infra/blob/main/spec/openapi.yml)
and re-run `make codegen`.
- Schema changes surfaced in the generated clients:
`SandboxMetric.memCache` (new required int64 — also exposed on the
public `SandboxMetrics` wrapper in both SDKs), `NodeStatus` gains
`standby`, `TeamUser.email` becomes nullable + deprecated, and `POST
/v3/templates` gains a `403` response.
- Upstream-only spec changes (not generated because the client filters
by tag): new `AuthProviderBearerAuth`/`AuthProviderTeamAuth` security
schemes, new admin endpoints for team API keys, and a `clusterID` query
param on `GET /nodes`.

## Summary
- Fixes#1349: `Template.fromDockerfile` (JS) and
`Template.from_dockerfile` (Python) silently dropped intermediate
sources from multi-source `COPY`/`ADD`, keeping only the first one and
producing broken images without warning.
- Both parsers now emit one `copy()` call per source to the same
destination (matching Docker semantics), preserving `--chown` across all
calls.
- Added tests in both SDKs (multi-source COPY, and multi-source COPY
with `--chown`), plus changesets for `e2b` and `@e2b/python-sdk`.
## Test plan
- [x] `pnpm run test tests/template/methods/fromDockerfile.test.ts` (JS)

Set limit for max concurrent inflight connection, with burst traffic it
could happen that the number of connection overwhelms the underlaying
infrastructure or at least saturate it to the point each request is too
slow to succeed and blocking the rest
## Summary
- Extends AbortSignal support (introduced for Sandbox in #1328) to
`Template.build`, `buildInBackground`, `getBuildStatus`, `exists`,
`assignTags`, `removeTags`, and `getTags`. Aborting the signal cancels
in-flight requests and, for `Template.build`, the status-polling loop.
- Refactors signal+timeout plumbing: `ConnectionConfig` now stores
`signal`, and `ApiClient` / `VolumeApiClient` auto-apply it (plus
`requestTimeoutMs`) to every request via a custom fetch wrapper. The 22
explicit \`signal: config.getSignal(...)\` lines across sandboxApi.ts
and volume/index.ts are dropped.
- Volume's \`FILE_TIMEOUT_MS\` overrides move one level up into the
\`VolumeConnectionConfig\` constructor. Dead
\`VolumeConnectionConfig.getSignal()\` removed.
## Test plan
- [x] \`pnpm run typecheck\` / \`lint\` / \`format\`
- [x] New \`tests/template/abortSignal.test.ts\` covering all 8 Template
entry points (MSW-based)
- [x] Existing \`tests/sandbox/abortSignal.test.ts\`,

## Summary
- `AsyncWatchHandle.stop()` and `AsyncCommandHandle.disconnect()`
previously only cancelled the consumer task and left the underlying
server-streaming gRPC call open — the `await self._events.aclose()` was
commented out as a Python 3.8 `RuntimeError` workaround. On long-lived
sandboxes this leaks one stream per call and eventually produces
`Code.internal: error creating watcher: too many open files`.
- The SDK now pins `python = "^3.10"`, so the workaround is removed.
`stop()`/`disconnect()` cancel the consumer task, await it, then
`aclose()` the async generator. The JS SDK already aborts the underlying
request via `AbortController`, so no JS change is needed.
## Test plan
- [ ] CI: `pnpm run format`, `pnpm run lint`, `pnpm run typecheck`
(passed locally)
- [ ] CI: `tests/async/sandbox_async/files/test_watch.py` and async
command tests still pass
- [ ] Reproduce the leak: in a long-lived async sandbox, repeatedly
create+stop a watcher and confirm fd count no longer climbs

## Summary
- `e2b auth login` previously crashed on headless machines (no
`xdg-open`) with an unhandled `error` event from the spawned browser
process.
- Attach an `error` listener (and `.catch`) to the `open` call; on
failure, print the login URL so the user can open it manually.
- Added a changeset for `@e2b/cli` (patch).
## Test plan
- [ ] On a headless Linux box without `xdg-open`, run `e2b auth login`
and confirm the CLI prints the manual URL instead of crashing.
- [ ] On macOS/Linux with a desktop, confirm the browser still opens
automatically and login completes.

## Summary
When `lifecycle.on_timeout` is set it wins; otherwise we fall back to
the `auto_pause` argument.
Previously the Python SDKs subscripted `lifecycle["on_timeout"]`, which
raised `KeyError` if a caller passed a `lifecycle` dict missing that key
(TypedDict is not enforced at runtime). The JS SDK silently used the
whole `lifecycle` object even when `onTimeout` was undefined. In both
cases, mixing `lifecycle` and `auto_pause` had inconsistent and
surprising behavior across the public surfaces (`create` vs
`beta_create`).
Now both SDKs use `.get`/optional chaining on `on_timeout` and only
treat `lifecycle` as authoritative when that field is actually present.
Touched files:
- `packages/python-sdk/e2b/sandbox_async/sandbox_api.py`

## Summary
- Add optional `name` parameter to `createSnapshot` / `create_snapshot`
in the JS and Python SDKs so callers can name the resulting snapshot
template.
- Return the `names` field from the snapshot API on `SnapshotInfo` (both
in `createSnapshot` responses and in `listSnapshots` paginator results)
so callers can discover the namespaced snapshot names.
- Includes a changeset (`patch` for `e2b` and `@e2b/python-sdk`).
## Test plan
- [ ] `pnpm run format`, `pnpm run lint`, `pnpm run typecheck` all pass
locally
- [ ] Integration tests on a sandbox with valid credentials:
`sandbox.createSnapshot({ name: 'my-snap' })` returns non-empty `names`

## Summary
- Replace the sequential `for sandbox in sandboxes: await
sandbox.kill()` teardown in `async_sandbox_factory` with
`asyncio.gather(..., return_exceptions=True)` so a failure on one kill
no longer blocks cleanup of the rest, and teardown runs concurrently.
- Hoist the `_test_failed` check above the loop so the failure log is
printed once per fixture rather than per sandbox.
## Test plan
- [ ] `pnpm run format`, `pnpm run lint`, `pnpm run typecheck`
(python-sdk) all pass
- [ ] `pnpm run test` against affected python async sandbox tests

Enables HTTP/2 for JS SDK sandbox envd traffic in Node by routing envd
RPC/API requests through undici with an HTTP/2-enabled dispatcher.
Non-Node runtimes continue to use global fetch. Management API and

Requires bumping node from >=20 to >= 20.18.1 for undici
## Summary
Adds a patch changeset for the `e2b` JS SDK to cover #1306 (commit
bd99b23c1), which removed the unused `npm-check-updates` devDependency
to clear the remaining `tar@6` Dependabot security alerts.
The original PR landed without a changeset, so the next release would
skip publishing the SDK despite the `package.json` change. This file
ensures the dependency cleanup gets a proper patch bump.
## Test plan
- [x] `.changeset/drop-npm-check-updates.md` follows the repo's existing
changeset format (frontmatter + summary line)
- [ ] Changesets bot picks up the entry on the PR

## Summary
Resolves the remaining 6 high-severity Dependabot alerts for `tar` on
the default branch. `tar@6.2.1` was being pulled in transitively via
`npm-check-updates@16 -> pacote@15 / cacache -> tar@^6`, and
Dependabot's `<= 7.5.10` ranges include 6.x semver-wise. Since
`npm-check-updates` was declared as a `devDependency` but never actually
invoked anywhere (no script, CI workflow, or doc references it),
removing it entirely is cleaner than bumping it — alerts cleared with
zero risk of regression.
After removal, the lock contains only `tar@7.5.12`, which satisfies all
six advisories.
## Test plan
- [x] `pnpm run lint` (js-sdk + cli)
- [x] `pnpm run typecheck` (js-sdk + cli)
- [x] `pnpm run format` (js-sdk + cli)
- [x] tar-related unit tests pass (`tests/template/utils`,

(with constraint update in `pyproject.toml`), pytest-asyncio 0.23 → 1.3
(required for pytest 9), python-dotenv 1.2.2, pygments 2.20.0, requests
2.33.1, black 26.3.1; removed 4 now-unused `# ty: ignore` directives
that pytest 9's stricter type signatures made obsolete.

## Summary
Consolidates the fix and tests from #1285 and #1293 into a single PR.
- **js-sdk**: `uploadFile` used to pass a Node `Readable` directly to
`fetch`, causing undici to fall back to `Transfer-Encoding: chunked`. S3
presigned PUT URLs reject chunked with 501 NotImplemented. Fix buffers
the archive first so `Content-Length` is set. Includes:
- Regression test that spins up a local HTTP server and asserts
`Content-Length` is set and matches the body, and `Transfer-Encoding` is
not chunked.
- Type-fix for the CLI's typecheck (cast `Pack` →
`AsyncIterable<Buffer>`).
- Dynamic import of `node:stream/consumers` so the browser bundle
doesn't pull it in.
- **python-sdk**: Adds sync + async regression tests for `upload_file`
that guard against the same class of bug (someone swapping
`tar_buffer.getvalue()` for a stream/generator). No Python code change —
the current implementation already passes bytes to `httpx.put(...,
content=...)`.
Authorship of the original JS fix commit preserved (truffle-dev).
Closes#1243.
## Test plan
- [x] `pnpm run test tests/template/uploadFile.test.ts` — passes
- [x] `pnpm run typecheck` / `lint` clean across js-sdk and cli
- [x] `poetry run pytest tests/sync/template_sync/test_upload_file.py

## Summary
- Bumps metrics polling from 15s to 30s in Python async/sync and JS SDK
tests so the backend has enough headroom to populate metrics under load
— this test was the new #1 CI offender (5/9 Python runs and 4/10 JS runs
failed).
- Raises the async Python sandbox timeout from 20s to 60s for parity
with sync, and adds per-test timeout overrides
(`@pytest.mark.timeout(60)` / `{ timeout: 60_000 }`) so polling can
complete under the default 30s pytest/vitest cap.
- Happy path is unchanged: the loop still breaks as soon as metrics
appear.
## Test plan
- [x] `pnpm run format`, `pnpm run lint`, `pnpm run typecheck` pass
- [x] `test_sbx_metrics` (Python async) passed locally in 8.4s
