Add path validation to the copy method in both JS and Python SDKs to
ensure source paths are always relative and don't escape the context
directory.
This prevents:
- Absolute paths like /absolute/whatever (Unix) or C:\whatever (Windows)
- Path traversal attacks like ../whatever or ./foo/../../../bar
The validation works cross-platform using Node's
path.isAbsolute/normalize and Python's os.path.isabs/normpath plus
PureWindowsPath for detecting Windows paths on Unix.

previously-accepted absolute or escaping paths, which could break some
consumers; logic is localized and well-covered by tests.

> **Overview**
> Prevents path traversal in template `copy` operations by validating
`src` is *relative* and does not escape the context directory (rejects
absolute paths and `..`-based escapes) in both the JS and Python SDKs.
>
> Updates `copyItems`/`copy_items` error handling to preserve the
caller’s stack trace when validation fails, adds unit coverage for the
new path validator plus new stack-trace tests for absolute-path

Fixes issue with missing `restore` and `reset` functionality on the
async git sandboxes.
Consolidate shared git helpers by moving remote URL argument
construction and
parsing into the git utilities package. Sync and async git modules now
reuse
the same builders where possible, with tests to ensure no drift.

# Sandbox Git Commands
Adds Git support to the sandbox class. This allows the sandbox to manage
git via standard clone, checkout, branch, add, pull, and push commands
without needing to use commands.run. The API mirrors common Git
workflows while handling sandbox-specific concerns like auth injection
and safe remote handling.
**Python example**
```python
from e2b import Sandbox
sandbox = Sandbox.create()
repo_path = '/home/user/my-repo'
# Optional: set author for commits
sandbox.git.configure_user('Your Name', 'you@example.com')
# Clone or init
sandbox.git.clone('https://github.com/org/repo.git', path=repo_path)
# or
sandbox.git.init(repo_path, initial_branch='main')
# Make a change
sandbox.files.write(f'{repo_path}/README.md', '# Hello\n')
# Commit
sandbox.git.add(repo_path, files=['README.md'])
sandbox.git.commit(repo_path, message='Initial commit')
# Branching
sandbox.git.create_branch(repo_path, 'feature1')
# or
sandbox.git.checkout_branch(repo_path, 'main')
# Push
sandbox.git.remote_add(repo_path, 'origin', 'https://github.com/org/repo.git', overwrite=True)
sandbox.git.push(repo_path, remote='origin', branch='main', set_upstream=True)
```
**JavaScript / TypeScript example**
```ts
import { Sandbox } from 'e2b'
const sandbox = await Sandbox.create()
const repoPath = '/home/user/my-repo'
await sandbox.git.configureUser('Your Name', 'you@example.com')
await sandbox.git.clone('https://github.com/org/repo.git', { path: repoPath })
// or
await sandbox.git.init(repoPath, { initialBranch: 'main' })
await sandbox.files.write(`${repoPath}/README.md`, '# Hello\n')
await sandbox.git.add(repoPath, { files: ['README.md'] })
await sandbox.git.commit(repoPath, { message: 'Initial commit' })
await sandbox.git.createBranch(repoPath, 'feature1')
await sandbox.git.checkoutBranch(repoPath, 'main')
await sandbox.git.remoteAdd(repoPath, 'origin', 'https://github.com/org/repo.git', {
overwrite: true,
})
await sandbox.git.push(repoPath, { remote: 'origin', branch: 'main', setUpstream: true })
```
**Main commands**
- `clone`: Clone a repo into the sandbox. Supports `branch`, `depth`,
optional `username` + `password` for private repos, and
`dangerously_store_credentials` / `dangerouslyStoreCredentials` to keep
credentials in the remote URL.
- `init`: Initialize a new repo. Supports `initial_branch` /
`initialBranch` and `bare`.
- `status`: Get parsed `git status --porcelain -b` info.
- `branches`: List branches and current branch.
- `create_branch` / `createBranch`: Create and check out a new branch.
- `checkout_branch` / `checkoutBranch`: Switch to an existing branch.
- `delete_branch` / `deleteBranch`: Delete a branch. Supports `force`.
- `add`: Stage files. Supports explicit files or `all`.
- `commit`: Create a commit. Supports author override and `allow_empty`.
- `reset` / `reset`: Reset `HEAD` (supports modes like `soft`, `mixed`,
`hard`, etc.) and optional paths.
- `restore` / `restore`: Restore files or unstage changes (`worktree` /
`staged`) from a source ref.
- `pull`: Pull from a remote. Supports `remote`, `branch`, and optional
auth.
- `push`: Push to a remote. Supports `remote`, `branch`, `set_upstream`,
and optional auth.
- `remote_add` / `remoteAdd`: Add a remote. Supports `overwrite` and
`fetch`.
- `remote_get` / `remoteGet`: Read a remote URL.
- `set_config` / `setConfig`: Set a git config value. Supports `scope`
(`global`, `local`, `system`), and `path` for local scope.
- `get_config` / `getConfig`: Read a git config value. Supports the same
`scope` options and returns `None` / `undefined` if unset.
- `dangerously_authenticate` / `dangerouslyAuthenticate`: Persist
credentials via the git credential helper (global).
- `configure_user` / `configureUser`: Set default `user.name` and
`user.email` for commits.
- `create_github_repo` (Python only): Create a GitHub repo from inside
the sandbox and optionally add it as a remote.
**Status shape**
- `status` returns a `GitStatus` with `current_branch` /
`currentBranch`, `upstream`, `ahead`, `behind`, `detached`, and
`file_status` / `fileStatus`.
- `file_status` entries include `name`, `status`, `index_status` /
`indexStatus`, `working_tree_status` / `workingTreeStatus`, `staged`,
and optional `renamed_from` / `renamedFrom`.
- Convenience helpers include: `is_clean` / `isClean`, `has_changes` /
`hasChanges`, `has_staged` / `hasStaged`, `has_untracked` /
`hasUntracked`, `has_conflicts` / `hasConflicts`, plus counts
(`total_count` / `totalCount`, `staged_count` / `stagedCount`,
`unstaged_count` / `unstagedCount`, `untracked_count` /
`untrackedCount`, `conflict_count` / `conflictCount`). In Python these
are properties on the `GitStatus` object; in JS they are fields on the
returned object.
**Notes**
- For private HTTPS remotes, pass `username` + `password` (token) on
`clone`, `pull`, or `push`.
- Use `remote_add` / `remoteAdd` with `overwrite=True` to update an
existing remote URL and `fetch=True` to fetch after.
- Use `dangerously_authenticate` / `dangerouslyAuthenticate` only when
you want to persist credentials globally on the sandbox.

## Summary
The public API accepts `Optional[float]` for timeout parameters (e.g.,
`60.0`), but `_create_stream_timeout` was typed as `Optional[int]` and
passed the value directly to `str()`, producing `'60000.0'` instead of
`'60000'`.
The Go backend's `strconv.ParseInt` fails on float strings, causing
'invalid syntax' errors for valid timeout values.
## Changes
- Updates type hint to `Optional[float]` for consistency with public API
- Wraps `timeout * 1000` in `int()` before `str()` conversion
## Test
```python
# Before: str(60.0 * 1000) -> '60000.0' (fails ParseInt)
# After: str(int(60.0 * 1000)) -> '60000' (works)
```

## Summary
- Fixes garbled Unicode and box-drawing character rendering when running
tmux inside E2B sandboxes
- Adds `LANG=C.UTF-8` and `LC_ALL=C.UTF-8` environment variable defaults
to PTY creation in both JS/TS and Python SDKs
## Problem
When running applications like Claude Code inside tmux in an E2B
sandbox, Unicode characters and box-drawing glyphs render incorrectly:
**Before (broken):**
- Box-drawing characters appear as broken dashes
- Text alignment is garbled
- The Claude mascot renders as `------` instead of proper pixel art
**After (fixed):**
- Proper Unicode rendering
- Correct box-drawing characters
- Properly aligned text
## Root Cause
The PTY session was created with `TERM=xterm-256color` but without UTF-8
locale settings. Running `locale` in the sandbox showed:
```
LANG=
LC_CTYPE="POSIX"
LC_ALL=
```
tmux requires UTF-8 locale settings to properly render Unicode
characters. Without them, it falls back to ASCII-only rendering.
## Solution
Set `LANG` and `LC_ALL` to `C.UTF-8` by default when creating PTY
sessions. This locale is:
- Available on most modern Linux distributions
- Provides UTF-8 character encoding
- Portable and doesn't require specific locale packages
The fix uses `setdefault` (Python) / nullish coalescing (JS) to allow
users to override these values if needed.
## Files Changed
| File | Change |
|------|--------|
| `packages/js-sdk/src/sandbox/commands/pty.ts` | Add LANG and LC_ALL
defaults |
| `packages/python-sdk/e2b/sandbox_async/commands/pty.py` | Add LANG and
LC_ALL defaults |
| `packages/python-sdk/e2b/sandbox_sync/commands/pty.py` | Add LANG and
LC_ALL defaults |

What was happening is that the following snippet:
```dockerfile
CMD ["sleep", "20"]
```
Was incorrectly converted to:
```
sleep, 20
```

> [!NOTE]
> Preserve Dockerfile USER/WORKDIR when provided and only apply E2B
defaults if absent, with tests and CLI fixtures updated accordingly.
>
> - **Dockerfile parsing (SDKs)**:
> - **JS (`packages/js-sdk/src/template/dockerfileParser.ts`)**: Track
`USER`/`WORKDIR` usage and only set E2B defaults (`user`, `/home/user`)
if not specified; keep Docker defaults (`root`, `/`) initially.
> - **Python
(`packages/python-sdk/e2b/template/dockerfile_parser.py`)**: Same
behavior—preserve explicit `USER`/`WORKDIR`, fallback to defaults only
when absent.
> - **Tests**:
> - **JS**: Add tests for default vs. custom `USER`/`WORKDIR` in
`fromMethods.test.ts`.
> - **Python (async/sync)**: Add analogous tests in
`test_from_methods.py`.
> - **CLI template fixtures**:
> - Update expected outputs to remove redundant
`.set_user('user')`/`.set_workdir('/home/user')` when already specified;
minor ordering tweak for `.setStartCmd` in TS fixture.
> - **Changeset**:
> - Minor version bumps for `@e2b/python-sdk` and `e2b`; note: keep
Docker `WORKDIR` and `USER` if specified.

> Reuses a singleton httpx transport/client across the SDK, introduces a
generic retry decorator for connect calls, and refactors code/tests to
use the shared clients and fixtures.
>
> - **SDK (transport/client reuse)**
> - Add global `limits` (configurable via `E2B_*` env vars) and switch
`ApiClient` to accept `transport` instead of `limits`.
> - Introduce `e2b.api.client_async/client_sync` with `get_transport()`
(singleton) and `get_api_client()`; update `Sandbox`/`AsyncSandbox`,
paginators, and sandbox APIs to use them.
> - Remove per-class `_limits` from `SandboxBase`/`TemplateBase`; merge
extra headers correctly; pass `E2b-Sandbox-Port` as string.
> - Template build flows (sync/async) now reuse the API client's
underlying httpx client for file uploads.
> - **Connect client** (`e2b_connect/client.py`)
> - Add `_retry` decorator and apply to unary/server-stream methods;
simplify reconnection logic; minor typing/headers cleanups.
> - **Tests**
> - Add retry unit tests; introduce
`sandbox_factory`/`async_sandbox_factory` and a session `event_loop`;
refactor tests to use factories and shared transports; adjust tar
archive expectations.
> - **Misc**
> - Add `.editorconfig`, CLI `.envrc`, and changeset entries.

first.
<!-- CURSOR_SUMMARY -->
---
> [!NOTE]
> Adds support to override the sandbox API URL (E2B_SANDBOX_URL) across
JS/Python SDKs, centralizes sandbox host/url logic with headers, and
updates CI to build the SDK before CLI.
>
> - **SDKs (JS & Python)**
> - Add `sandboxUrl` support in `ConnectionConfig` (env var
`E2B_SANDBOX_URL`), with new helpers `getSandboxUrl`/`getHost` and
shared `envdPort`.
> - Refactor sandbox initialization to use
`ConnectionConfig.getSandboxUrl(...)` and `getHost(...)`.
> - Always attach sandbox headers `E2b-Sandbox-Id` and
`E2b-Sandbox-Port` to sandbox and connect requests.
> - Python: thread `sandbox_url` through opts; update async/sync connect
calls to pass headers; minor fix to default `headers=None` in
`e2b_connect.client.Client` stream prep.
> - **CI**
> - Build `packages/js-sdk` before `packages/cli`; set step
`working-directory` for build/test.
> - **Dependencies**
> - Point `e2b` dependency in lockfile to local `../js-sdk` link.

- Individual tests must complete in less than 5 minutes
- Add a `make test` option that runs tests
- Upgrade poetry to 2.1.1 (the lock file was generated by this version,
so this just matches what we already expect)
<!-- CURSOR_SUMMARY -->
> [!NOTE]
> Ensure file uploads honor ignore patterns (incl. .dockerignore),
refactor file discovery/tar streaming in JS/Python SDKs, and add
comprehensive tests.
>
> - **File upload behavior**:
> - JS/TS and Python uploads now pass `ignorePatterns` (merged from
`fileIgnorePatterns` and `.dockerignore`) to tar creation, ensuring
ignored files aren’t uploaded.
> - **Refactor/Utilities**:
> - Rename `getAllFilesForFilesHash` -> `getAllFilesInPath` with
optional directory inclusion in both SDKs.
> - Implement `tar_file_stream` (JS and Python) to build archives from
`getAllFilesInPath`, with `noDirRecurse` and symlink control.
> - Hashing functions updated to use `getAllFilesInPath`.
> - Type tweak: allow `None` in Python `stack_traces` during build wait.
> - **Integration**:
> - JS `uploadFile` and Python async/sync `upload_file` now use tar
streaming with ignore patterns; JS `Template` wires ignore patterns into
uploads.
> - **Tests**:
> - Add extensive tests for `getAllFilesInPath` and `tar_file_stream` in
JS and Python, covering ignore patterns, directories, sorting, and
symlinks.
> - Remove obsolete tests relying on old function names.
> - **Meta**:
> - Changeset entries for `@e2b/python-sdk` and `e2b` (patch).
