Moves 12 packages from internal/ to pkg/ (config, id, validate, events, db,
auth, lifecycle, scheduler, channels, audit, service) so they can be imported
by the enterprise repo as a Go module dependency.
Introduces pkg/cpextension (shared Extension interface + ServerContext) and
pkg/cpserver (Run() entrypoint with functional options) so the enterprise
main.go can call cpserver.Run(cpserver.WithExtensions(...)) without duplicating
the 20-step server bootstrap. Adds db/migrations/embed.go for go:embed access
to OSS SQL migrations from the enterprise module.
cmd/control-plane/main.go is reduced to a 10-line wrapper around cpserver.Run.
Start long-running processes (web servers, daemons) without blocking the
HTTP request. Leverages envd's existing background process support
(context.Background(), List, Connect, SendSignal RPCs) and wires it
through the host agent and control plane layers.
New API surface:
- POST /v1/capsules/{id}/exec with background:true → 202 {pid, tag}
- GET /v1/capsules/{id}/processes → list running processes
- DELETE /v1/capsules/{id}/processes/{selector} → kill by PID or tag
- WS /v1/capsules/{id}/processes/{selector}/stream → reconnect to output
The {selector} param auto-detects: numeric = PID, string = tag.
Tags are auto-generated as "proc-" + 8 hex chars if not provided.
- envd: reject non-regular files (devices, pipes, sockets) in GetFiles
to prevent infinite reads from /dev/zero, /dev/urandom etc.
- host agent: add context cancellation check in ReadFileStream loop
with proper Connect error codes
- frontend: abort in-flight file reads on file switch, directory
navigation, and component teardown via AbortController
- frontend: guard against abort errors surfacing in UI, use try/finally
for fileLoading state
Implement three new recipe commands for the admin template builder:
- USER <name>: creates the user (adduser + passwordless sudo), switches
execution context so subsequent RUN/START commands run as that user
via su wrapping. Last USER becomes the template's default_user.
- COPY <src> <dst>: copies files from an uploaded build archive
(tar/tar.gz/zip) into the sandbox. Source paths validated against
traversal. Ownership set to the current USER.
- ENV persistence: accumulated env vars stored in templates.default_env
(JSONB) and injected via PostInit when sandboxes are created from the
template, mirroring Docker's image metadata approach.
Supporting changes:
- Pre-build creates wrenn-user as default (via USER command)
- WORKDIR now creates the directory if it doesn't exist (mkdir -p)
- Per-step progress updates (ProgressFunc callback) for live UI
- Multipart form support on POST /v1/admin/builds for archive upload
- Proto: default_user/default_env fields on Create/ResumeSandboxRequest
- Host agent: SetDefaults calls PostInitWithDefaults on envd
- Control plane: reads template defaults, passes on sandbox create/resume
- Frontend: file upload widget, recipe copy button, keyword colors for
USER/COPY, fixed Svelte whitespace stripping in step display
- Admin panel defaults to /admin/templates instead of /admin/hosts
- Migration adds default_user and default_env to templates and
template_builds tables
Removed the `connect.NewError(connect.CodeInternal, ...)` wrapper in the
Server's MakeDir proxy handler. Previously, this wrapper was catching
specific agent errors (like CodeAlreadyExists) and casting them into
generic Code 13 (Internal) errors, stripping the gRPC metadata.
This change allows the control-plane to act as a transparent pipeline,
ensuring the API gateway can properly interpret and route specific
filesystem failures.
Wire envd's existing PTY process capabilities through the full stack:
hostagent proto (4 new RPCs: PtyAttach, PtySendInput, PtyResize, PtyKill),
envdclient, sandbox manager, and a new WebSocket endpoint at
GET /v1/sandboxes/{id}/pty with bidirectional JSON message protocol.
Sessions use tag-based identity for disconnect/reconnect support,
base64-encoded PTY data for binary safety, and a 120s inactivity timeout.
Plumb ListDir, MakeDir, and RemovePath through all layers:
REST API → host agent RPC → envdclient → envd. These endpoints
enable a web file browser for sandbox filesystem interaction.
New endpoints (all under requireAPIKeyOrJWT):
- POST /v1/sandboxes/{id}/files/list
- POST /v1/sandboxes/{id}/files/mkdir
- POST /v1/sandboxes/{id}/files/remove
