Turtle 38c7a9fbf4 feat(release): publish package source, declaration maps, and documentation (#5884)
* feat(release): publish package source, declaration maps, and documentation

Every release member publishes its TypeScript source and the declaration
maps that resolve into it, and @deepseek-ai/dsh publishes the repository
Markdown documentation staged from docs/ at prepack time.

The ./src/* export most members already declared now resolves for an
installed consumer, and a consumer editor follows a declaration to the
implementation. Bundled JavaScript maps stay unpublished; the vendored
family and the Desktop runtime file policy are unchanged.

Rationale: .agents/notes/implemented/process/2026-10-08-published-source-and-docs.md

* feat(release): publish JavaScript maps and compress bundles

Every emitted JavaScript map ships beside the bundle it describes, and the
workspace build and the client preset compress bundles without mangling
identifiers.

The documentation payload now mirrors the website publication manifest and
is removed again by `postpack`; Desktop and the Python executable exclude
the published source, documentation, and maps; `clean` removes a staged
copy. Typert's publication contract gains the Remote declaration map.

* fix(release): keep node bundles readable for the worker image

The browser worker image lowers `yield*` only as a whole statement and
rewrites `for await` loops by their source layout, so compressed node-side
entries either fail that lowering or lower to unparseable code. Only the
browser bundles keep compression, which removes about a third of their text.

The bundle-purity assertion now matches the module-loader call regardless of
the quote style compression picks, and the release-pack fixture exercises
the installed package's new documentation requirement.

* feat(release): publish the whole documentation tree

`@deepseek-ai/dsh` copies `docs/` in full instead of the website's page
set: the maintainer documents, the generated migration records, the
translation guidelines, and the `*.i18n.yaml` consistency records ship
with the installed package, so the documentation's own links resolve
without a checkout.

* feat(release): publish the upgrade guides with the documentation

The staged documentation keeps the website's page set and adds every
`docs/upgrade-guide/` document, which is what an installed reader consults
when a released change breaks something. The rest of the maintainer tree
stays out.

* test(release): expect source and maps in master's new payload cases

* feat(release): keep installed docs and source readable in Desktop

Desktop keeps the published src/ and docs/ trees inside app.asar, and
every model shell call receives DSH_INSTALL_DIR and DSH_NODE_EXECUTABLE
so an agent can read them through Electron's Node mode. Staging also
generates docs/upgrade-guide/README.md, an index of the upgrade guides
grouped by the release they upgrade from.

Minified client bundles print string literals with backticks: the
worker image packer now recognizes those chunk requests, client license
banners are prepended after minification so their text survives, and
the affected artifact tests accept either quote.

* test(desktop): read archived docs through the Windows PowerShell form

Regenerate the config catalog for the shifted shell-env source line.

* test(desktop): wait for the GUI-subsystem Electron process from PowerShell

* build(release): publish source and maps from the message-quotes package

* build(release): publish source and maps from packages new on master

* build(release): publish source and maps from the tool-office package

Managed SSH subprocess and terminal behavior for Bash, LSP and Node runtime consumers. package-reference

@deepseek-ai/dsh-subprocess-ssh

English | 中文

Summary

dsh-subprocess-ssh implements ctx.subprocess using the shared SSH helper. Executable lookup, ordinary processes, fd 7 control traffic and terminal sessions run beside the SSH filesystem. Remote native process owners govern termination and quiescence; consumers continue to own command semantics, output limits and execution deadlines.

Table of Contents


Use this package

Mount this provider with dsh-ssh and its filesystem provider. It has no deployment configuration of its own. resolveExecutable() checks the remote executable namespace; fully specified spawn requests supply the remote cwd, environment, stream dispositions and cleanup grace.

Ordinary spawn returns a handle while remote allocation proceeds. Piped stdin and the optional duplex control endpoint accept writes during allocation. Terminal allocation, writes, foreground inspection, signals and termination retain their asynchronous interfaces.

Terminal requests forward shellActivity to the execution provider, and inspectActivity() returns its validated state and revision. Opted-in terminals remain addressable after root exit until their owner explicitly terminates them; the SSH helper lease still governs connection-level cleanup.

A direct exit reported by done does not prove managed-range quiescence; waitForExit() observes that separately. Its optional signal bounds the entire observation, including pending allocation and termination, and cancellation returns false without stopping the process. An already confirmed empty range returns true; genuine observation failures reject. terminate() targets the same remote owner. Connection loss rejects unconfirmed work, and automatic replay never follows an ambiguous launch or mutation.


Terminal shell facts and executable verification come from the remote helper. Lookup misses remain distinct from SSH failures. PTY creation forwards the caller's terminalType, and resize() updates the remote terminal without replacing its process.

Implementation internals — click to expand

The helper reserves and authenticates all required streams before launch. Stdout, stderr, stdin and fd 7 use separate SSH channels. Collected output publishes a final bounded raw-tail snapshot with whole-stream byte offsets, so network lag cannot change the completed observation. Optional spill files use the local provider’s private retained-output directory on the remote host.

Remote execution delegates to subprocess-local. Native process ownership and platform fallbacks therefore have the same meaning as local execution on that remote OS. SSH carries requests and observations; it does not itself confine the payload.


Further Exploration


Model Experience

Indirectly, through Bash, terminal, LSP and ptc-runtime consumers, which present their existing results and remote paths.

KV Cache effect

This provider contributes no request-prefix content. Its consumers own model-visible tools and results.

Known Limitations and Deferred Work

  • Completed spill files survive connection disposal and remain available until external temporary-file cleanup.
  • Callers must consume or close raw output streams. Destroying public stdout or stderr closes its matching transport, including when destruction precedes remote allocation. Independent channels allow control progress when stdout is paused, but do not remove per-stream backpressure or shared-network congestion.
  • Loss of the SSH connection leaves remote termination unconfirmed from the client; lease cleanup is a remote action, not a successful client acknowledgement.
