Problem

In the desktop Add environment dialog (SSH), the Port field keeps only the number a value starts with. 22.5 connects to port 22, 1e3 to port 1, 2222garbage to port 2222, with no error, so a mistyped or pasted port silently targets a different port. OpenSSH itself rejects all of these values.

Change

parseManualDesktopSshTarget now accepts the explicit port only when the trimmed value is all digits, which is the rule the inline host:2222 and [::1]:2222 forms already use. Anything else shows the existing "SSH port must be between 1 and 65535." error, the same one abc and 0 already get. Blank, padded (2222) and valid ports, inline ports and an explicit port overriding an inline one behave as before.

Scope and approval

A focused fix of an obvious bug in existing input validation, so no prior issue or discussion. One line in the parser plus a test. It adds no new feature or setting and keeps the existing error text.

Verification

• New describe("parseManualDesktopSshTarget") in ConnectionsSettings.logic.test.ts. On main, its 22.5, 1e3 and 2222garbage cases fail because the parser accepts them. With the fix, vp test run apps/web/src/components/settings/ConnectionsSettings.logic.test.ts passes 16/16.
• vp run check:changed: format, lint, knip, typecheck, tests and React Compiler checks pass.
• Desktop app on Linux, unpackaged build, host 192.0.2.10 (unreachable test address), Port 22.5, then Add environment.

Before: main accepts 22.5 and starts adding the environment.

After: the dialog shows the port error and adds nothing.

After: Port 22 still goes through.

Not checked:

• macOS and Windows desktop builds. The change is in shared web code with no platform branch.
• A real SSH connection. The test host is unreachable on purpose.

Prior PRs

None for this fix. #22683 moved the parser without changing it. Open #27876 edits a different helper in the same file (pairing URL scheme), and open #24449 and #12433 change SSH alias and known-host port handling elsewhere. None of them touch this parsing.

Approvability

Verdict: Approved at 613af9c

Macroscope's review found this PR approvable — Malformed SSH port values are now rejected instead of silently truncated, using the existing validation error path before connecting. Valid ports and default behavior remain unchanged.

Walkthrough

Manual SSH port parsing now rejects explicit values that contain non-digit characters. Tests cover decimal, exponential, and trailing-nonnumeric inputs, plus a whitespace-padded valid port.

Changes: Manual SSH port validation

Layer / File(s)	Summary
Validate manual SSH ports apps/web/src/components/settings/ConnectionsSettings.logic.ts, apps/web/src/components/settings/ConnectionsSettings.logic.test.ts	The parser accepts a port only when its trimmed value contains digits only. Tests check invalid inputs and confirm that a whitespace-padded 2222 parses as port 2222.

Add parser tests for blank and overriding explicit ports.

The new port handling is correct, but the test block does not cover two of its branches. A blank explicit port must keep an inline port. A non-empty explicit port must override it. A regression in either branch passes the current tests.

   it("accepts a padded explicit port", () => {
     expect(parseManualDesktopSshTarget({ host: "devbox", username: "", port: " 2222 " }).port).toBe(
       2222,

Verified in a real dev environment

verified unchanged head 613af9c21e8119406423f1387800d831dc46cadf on this linux boat vm. reproduced first on github/main at 955e2bfbb5c092c54ad795c8d379fec99702a6b5 in a separate worktree. stopped main before starting the pr. used the real linux electron client and ssh ipc, plus the dev web client with repository playwright and /usr/bin/google-chrome. no mocked bridge or provider.

• settings → environments → add environment → ssh, host 192.0.2.10, port 22.5: main entered Adding…; electron logged an ssh launch targeting port 22.
• the same flow on the pr rejects 22.5, 1e3, 2222garbage, 22 33, 0, and 65536 with SSH port must be between 1 and 65535.. no ssh ensure or launch appeared in the desktop log during those submissions.
• neighboring behavior: explicit 1 overrides host 127.0.0.1:2222 and invokes real ssh on port 1; a blank explicit port preserves 127.0.0.1:1; a blank port without an inline port invokes ssh on port 22. connection-refused and host-key errors return to the editable dialog.
• added the real git project /home/user/m014-verification through the web client, created a thread, selected codex gpt-6.1-sol, and submitted a read-only request. both terminal commands exited 0; the final response streamed into the client. the provider log records modelProvider: cliproxyapi and turn/completed with status completed.
• blacksmith: all 16 parser tests passed. vp run check:changed 15fe2832727893cbdd2214383f9f971474849695 --timeout 600 passed format, lint, both knip checks, affected typechecks, tests, and react compiler coverage. all 31 reported github checks pass. desktop builds passed for both revisions after installing the missing libsecret-1-dev worker dependency.

short runtime transcript:

main, explicit "22.5": ssh.remoteServer.launch.start { hostname: '192.0.2.10', port: 22 }
pr, six invalid values: validation error; no ssh ensure/launch dispatch
pr, explicit " 1 " overriding :2222: ssh -p 1; Connection refused
pr, blank explicit port with :1: ssh -p 1; Connection refused
pr, blank explicit port without inline port: ssh -p 22; Host key verification failed
codex: gpt-6.1-sol, modelProvider: cliproxyapi
pwd: /home/user/m014-verification (exit 0)
git status --short: no output (exit 0)
turn/completed: completed; final response: M014_VERIFIED

Not verified

• a successful ssh-managed environment installation or provider turn over its tunnel. real ssh was dispatched, but the tested destinations returned connection refusal or host-key errors.
• secure-storage-dependent pairing persistence. electron stalled against this vm's secret service, so the task client ran without that service and with its local environment disabled. the keychain was left alone.
• macos/windows desktop clients, native ios/android clients, relay/tunnel connections, and other providers. the changed form is desktop-only.

no source changes or pushes were needed. verification used gpt-6.1-sol through the codex harness in t3 code.

Re this review: on the port-test nitpick: we're leaving it out. This PR changes only the digit check on the explicit port (ConnectionsSettings.logic.ts:213). Blank-keeps-inline and explicit-overrides-inline work the same as on main, so those tests would pass on main. AGENTS.md asks for the fewest tests that fail on main, which is why c145724 trimmed the table to those cases.
