Fixes a batch of connection-handling bugs found in review, with unit
tests for each and a changeset for both SDKs.
- **Python**: cached HTTP transports are now keyed on the configured
proxy, so clients with different (or no) proxy settings no longer
silently reuse the transport built for the first proxy seen.
- **Python**: `request_timeout` now applies to control-plane API
requests — the underlying httpx client was previously built with no
timeout at all (`request_timeout=0` still disables it).
- **Python**: the server-stream parser no longer stalls or drops the
final envelope when the remaining payload is shorter than the 5-byte
envelope header; also removed the no-op `@_retry` decorators from the
streaming RPC methods to avoid confusion.
- **JS + Python**: an explicit `debug=False` / `debug: false` now
overrides `E2B_DEBUG=true` instead of being ignored.
- **JS**: the RPC logger no longer crashes requests with a `TypeError`
when a response contains protobuf int64 (`bigint`) fields (e.g.
`EntryInfo.size` returned by `files.list()`/`stat()` and `includeEntry`
watch events); they are logged as strings.
## Usage examples
```ts
// JS: logging RPCs whose responses carry int64 fields no longer throws
const sbx = await Sandbox.create({ logger: console })
await sbx.files.list('/')
// JS: force-disable debug mode even when E2B_DEBUG=true is set
const sbx2 = await Sandbox.create({ debug: false })
```
```python
# Python: per-call API timeout is now actually enforced
Sandbox.list(request_timeout=10)
# Python: clients with different proxies get their own transports
Sandbox.create(proxy="http://127.0.0.1:8080")
Sandbox.create() # no longer routed through the proxy above
```

Client-side counterpart to
[e2b-dev/infra#2930](https://github.com/e2b-dev/infra/pull/2930): adds
an `includeEntry`/`include_entry` option to filesystem directory
watching across the JS and Python (sync + async) SDKs, so each
`FilesystemEvent` can carry the affected entry's `EntryInfo`
(best-effort — unset for remove/rename-away events where the path no
longer exists). This regenerates the filesystem proto code from the
updated spec, threads the flag through `watchDir`/`watch_dir` (streaming
`WatchDir` and polling `CreateWatcher`), maps the new `entry` field onto
the event, and extracts a shared entry-mapping helper reused by
`list`/`getInfo`/`rename`. The option degrades gracefully: older
sandboxes (< envd 0.6.2) ignore it and leave `entry` unset, so there's
no hard version gate. Includes new watch tests for all three SDKs and a
minor-bump changeset for `e2b` and `@e2b/python-sdk`.
> Note: the entry-info tests require envd 0.6.2 (shipped by the infra
PR), so this should land with/after that deploy.
### Usage
**JavaScript**
```ts
const handle = await sandbox.files.watchDir(
'my-dir',
(event) => {
console.log(event.type, event.name, event.entry?.path, event.entry?.type)
},
{ includeEntry: true }
)
```
**Python (async)**
```python
def on_event(e):
print(e.type, e.name, e.entry.path if e.entry else None)
handle = await sandbox.files.watch_dir("my-dir", on_event=on_event, include_entry=True)
```
**Python (sync)**
```python
handle = sandbox.files.watch_dir("my-dir", include_entry=True)
for e in handle.get_new_events():
print(e.type, e.name, e.entry.path if e.entry else None)
```

Adds a `metadata` option to file uploads and surfaces persisted metadata
on every `EntryInfo` / `WriteInfo` returned by `getInfo`, `list`,
`rename`, and write responses, across the JS and Python (sync + async)
SDKs.
Metadata is sent as `X-Metadata-<key>: <value>` request headers and
persisted by envd as `user.e2b.*` extended attributes; the same map is
applied to every file in a multi-file upload. Keys and values must be
printable US-ASCII and keys are lowercased by the sandbox, so they may
differ in case when read back. Requires **envd 0.6.2 or later**.
This syncs the envd OpenAPI spec and filesystem proto with
[infra#2732](https://github.com/e2b-dev/infra/pull/2732) and regenerates
the JS/Python clients.
## Usage
**JavaScript / TypeScript**
```ts
// Single file
const info = await sandbox.files.write('report.txt', 'hello', {
metadata: { author: 'mish', purpose: 'demo' },
})
console.log(info.metadata) // { author: 'mish', purpose: 'demo' }
// Multiple files (same metadata applied to each)
await sandbox.files.writeFiles(
[
{ path: 'a.txt', data: 'A' },
{ path: 'b.txt', data: 'B' },
],
{ metadata: { source: 'import' } }
)
// Read it back
const stat = await sandbox.files.getInfo('report.txt')
console.log(stat.metadata) // { author: 'mish', purpose: 'demo' }
```
**Python**
```python
# Single file
info = sandbox.files.write("report.txt", "hello", metadata={"author": "mish"})
print(info.metadata) # {"author": "mish"}
# Multiple files (same metadata applied to each)
sandbox.files.write_files(
[
WriteEntry(path="a.txt", data="A"),
WriteEntry(path="b.txt", data="B"),
],
metadata={"source": "import"},
)
# Read it back
stat = sandbox.files.get_info("report.txt")
print(stat.metadata) # {"author": "mish"}
```
The async Python API is identical with `await`.
## Tests
Integration tests cover the round-trip across `write` / `getInfo` /
`list` / `rename`, octet-stream uploads, multi-file uploads,
overwrite-clears-stale-metadata, and metadata written directly as
`user.e2b.*` xattrs via `sandbox.commands.run` surfacing in `getInfo`.
They require a sandbox running envd 0.6.2+.

Aligns several behavioral and API-surface discrepancies between the JS
and Python SDKs found during a cross-SDK audit. **Python:**
`commands.send_stdin`/`CommandHandle.send_stdin` now accept `bytes`
(plus `request_timeout` on the handle), `git.reset` gets a typed
`GitResetMode` with JS-matching validation, `sandbox_url` is threaded
through `get_api_params` (and the dead `SandboxOpts` key removed), and
`from_image` requires both `username` and `password` when credentials
are given. **JS:** `getFullInfo` was removed in favor of a single
`getInfo` that now includes `sandboxDomain` (matching Python's
`get_info`), `fromImage` requires both credentials, `getBuildStatus`
defaults `logsOffset` to `0`, `getMetrics`/`kill` short-circuit
consistently in debug mode (instance + static), and `requestTimeoutMs:
0` explicitly disables the request timeout. Tests were added on both
sides (git-arg validation, stdin bytes, credential validation,
timeout-0, connection config) and the CLI's `sandbox info` now uses
`getInfo`. See the changeset for the full per-SDK list.
## Usage examples
```ts
// JS: registry credentials now require both fields
Template().fromImage('registry.example.com/img:latest', { username: 'u', password: 'p' })
// JS: getInfo now exposes sandboxDomain (getFullInfo removed)
const info = await Sandbox.getInfo(sandboxId)
console.log(info.sandboxDomain)
// JS: disable the request timeout
await Sandbox.create({ requestTimeoutMs: 0 })
```
```python
# Python: send raw bytes to stdin
sandbox.commands.send_stdin(cmd.pid, b"hello")
# Python: typed git reset mode (validated)
sandbox.git.reset(repo, mode="hard")
# Python: registry credentials require both fields
Template().from_image("registry.example.com/img:latest", username="u", password="p")

Adds the previously-missing test coverage for `pty.kill()`, which was
untested across all three SDK implementations despite the rest of the
PTY API (create/connect/sendInput/resize) being well covered.
Each suite gets two tests covering both return paths of `kill()`:
- **Kill a live PTY** — asserts `kill()` returns `true`, then confirms
the process is gone via `kill -0 <pid>` (throws
`ProcessExitError`/`CommandExitException`).
- **Kill a non-existent PID** — asserts `kill()` returns `false`,
matching the documented not-found behavior.
The tests mirror the style of the existing `commands.kill` tests and
were verified to lint cleanly and be discovered by vitest/pytest (full
runs require a live sandbox).

Adds a `proxy` connection parameter to the JS SDK, mirroring the Python
SDK. When set, requests are routed through the given HTTP proxy via an
undici `ProxyAgent` dispatcher (fetchers are cached per-proxy so
non-proxy traffic is unaffected). It applies to control-plane API
requests, all requests made to the returned sandbox (REST plus
filesystem/commands/pty RPC), and volume requests. Behavior is unchanged
when no proxy is provided, and unit tests cover both the API and envd
fetch paths.
## Usage
```ts
import { Sandbox } from 'e2b'
// Routes API + all sandbox requests through the proxy
const sandbox = await Sandbox.create({
proxy: 'http://user:pass@127.0.0.1:8080',
})
await sandbox.files.write('/hello.txt', 'world')
// Also works when connecting to an existing sandbox
const sbx = await Sandbox.connect(sandboxId, { proxy: 'http://127.0.0.1:8080' })
```
> Proxying relies on the optional `undici` package and the Node runtime;
in browser/edge runtimes requests use global `fetch`, which has no proxy
support (same as the existing HTTP/2 dispatcher).

Reconciles divergences found while auditing the sync and async Python
SDK trees, keeping behavior equivalent across both.
- **Parameter ordering:** aligned `_create` and `Commands._start`
signatures to the public API and to each other, and reordered the
`Commands.connect` rpc args (`headers` before `timeout`) to match the
`_start` convention.
- **`pause` return:** the public `pause()` / `beta_pause()` are now
annotated `-> str` and actually return the sandbox ID (matching
`_cls_pause` and the class-method form, which already returned it)
instead of `-> None`; the `:return:` docstrings are restored.
- **Exceptions:** the internal "Body of the request is None" guard in
`sandbox_api` now consistently raises a bare `Exception` (matching the
volume client) instead of mixing `Exception`/`SandboxException` between
sync and async.
- **Misc:** async `Filesystem.write` now passes keyword args; the async
constructor reuses the cached `envd_api_url` property instead of
recomputing the sandbox URL; async pty `resize` gains a `-> None`
annotation.
- **Docstrings:** aligned the deprecation marker and
`get_metrics`/`write_files`/`kill` wording across sync/async, and fixed
a `**seconds**s` typo.
These are alignment/consistency fixes only; the deeper architectural
async-vs-sync splits (streaming-vs-polling `watch_dir`, pty `on_data`,
command output callbacks) are intentional and left untouched.

`Sandbox.connect` was attaching the data-plane envd headers
(`E2b-Sandbox-Id`, `E2b-Sandbox-Port`) to the control-plane `POST
/sandboxes/{id}/connect` call in both the sync and async SDKs. These
headers belong only on data-plane (filesystem/commands/pty) requests, so
this aligns the Python SDK with the JS SDK, which never sends them on
the connect call.
## Usage
No API change — `Sandbox.connect(sandbox_id)` (and the async equivalent)
behaves the same, just without the spurious headers on the control-plane
request.

makes the sync python python API http transport cache thread-local to
handle unsafe usage of the shared transport under pressure (e.g.
concurrent template builds). uses the same logic that we were using for
envd.
test
`test_sync_api_transport_cache_reuses_within_thread_and_isolates_across_threads`
fails on main, passes on branch.
Adds `sendStdin`/`send_stdin` and `closeStdin`/`close_stdin` directly on
the command handle (JS, Python sync, and Python async) so background
commands can be fed stdin and signalled EOF without reaching back to
`sandbox.commands` with the PID. The handle delegates to the existing
`Commands` methods via closures, mirroring how `kill` is wired, and also
adds the previously-missing `close_stdin`/`aclose_stdin` to the Python
`Commands` class (version-gated on `ENVD_ENVD_CLOSE`, matching JS).
PTY-created handles don't support these and raise a clear error, and the
existing PID-based `Commands.sendStdin` methods are untouched, so the
change is fully backward-compatible. Includes handle-based tests across
all three SDKs and a changeset bumping `e2b` and `@e2b/python-sdk` at
patch.

## Summary
The main API client already raised `RateLimitError` (JS) /
`RateLimitException` (Python) for HTTP 429, but the lower-level **envd**
HTTP and RPC layers fell through to a generic sandbox error, so the same
rate-limit condition surfaced as a different type depending on which
request path hit it. This maps envd 429 (and the equivalent gRPC
`ResourceExhausted` code) to the dedicated rate-limit error consistently
across the JS SDK and the Python sync/async SDKs. The JS RPC layer was
also missing the `ResourceExhausted` mapping entirely, which is now
added for parity with Python.
## Changes
- `js-sdk/src/envd/api.ts`, `python-sdk/e2b/envd/api.py` — envd HTTP 429
→ `RateLimitError`/`RateLimitException`
- `js-sdk/src/envd/rpc.ts` — added gRPC `Code.ResourceExhausted` →
`RateLimitError`
- Added unit tests for both the envd HTTP and RPC error mappers in JS
and Python
- Changeset (`e2b`: patch)
## Usage example
```ts
import { Sandbox, RateLimitError } from 'e2b'
try {
await sandbox.files.write('/tmp/file.txt', 'data')
} catch (err) {
if (err instanceof RateLimitError) {
// now reliably caught regardless of which request path was rate limited
}
}
```
```python
from e2b import RateLimitException
try:
sandbox.files.write("/tmp/file.txt", "data")
except RateLimitException:
...

## 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.
## Test plan

- [x] `pnpm exec vitest run tests/api/validateApiKey.test.ts

- 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)
- [x] `poetry run pytest
tests/{async,sync}/template_*/methods/test_from_dockerfile.py` (Python)
- [x] `pnpm run format` / `pnpm run lint`

## 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
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.

## 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

## Summary
Resolves all 31 open [Dependabot
alerts](https://github.com/e2b-dev/e2b/security/dependabot) across the
workspace.
- **npm** — added range-based `pnpm.overrides` to bump vulnerable
transitive deps to their patched versions: postcss, vite, lodash,
brace-expansion, picomatch (2.x + 4.x), yaml, @tootallnate/once,
smol-toml, flatted, and minimatch (3.x/5.x/9.x/10.x).
- **python-sdk** — bumped dev deps in `poetry.lock`: pytest 7.4 → 9.0.3
(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.
## Test plan
- [x] \`pnpm run typecheck\` passes
- [x] \`pnpm run lint\` passes
- [x] \`pnpm run format\` clean
- [x] CLI tests (80/80) and js-sdk/python-sdk unit tests pass;
integration tests not run locally (need \`E2B_API_KEY\`)
