fix: recognize the offckb daemon when its CLI path contains spaces - #533
Merged
Merged
Conversation
verifyDaemonIdentity tokenized the flat command line from 'ps -o args=' (macOS, or Linux without a readable /proc) with a quote-aware splitter. ps never quotes, so a CLI entry under a path with spaces (macOS ~/Library/Application Support/...) was cut at the first space, the script token never matched and 'offckb node stop' refused to stop a live daemon. Match the command line instead: try every space as the executable/script boundary and every later space (or the end) as the script end, accepting only a Node executable followed by exactly this installation's CLI entry (realpath-normalized, case-insensitive on Windows, quoted or not). The exact-argv path (/proc) and the start-time check are unchanged. Found during the review of #531.

…form The previous commit chose posix/win32 path rules from process.platform. Tests (and anything else) that override process.platform then compared paths with the wrong rules: on a Windows runner the node stop tests set platform to 'linux', so the '/path/to/offckb' token from the ps mock was resolved with posix rules while the CLI entry is a native 'D:\path\to\offckb', and every identity check failed. Default to the host's own path module (as before #533), including realpath and Windows case-insensitivity; the explicit platform argument is only used by unit tests that exercise another OS's command lines.
…nit tests On windows-latest, node-terminal-rpc timed out (5 s) in its first test: since #531, foreground startNode/nodeDevnet runs reapStaleMiners, which lists processes through PowerShell CIM on Windows and can take seconds on a cold runner (the suite already took ~5.4 s on the previous run). The second failure in that file was fallout from the timed-out test. Mock reapStaleMiners in node-terminal-rpc, node-quiet-mode and node-command like node-supervisor already does; the reaper has its own tests.

Summary
offckb node stop(and every other caller ofverifyDaemonIdentity: daemon start de-duplication,fiber stop/status) refused to recognize a live offckb daemon when the offckb CLI entry path contains a space, e.g. on macOS under~/Library/Application Support/...:Found by @RetricSu during the review of #531 (no separate issue).
Root cause
When no exact argv is available (macOS always; Linux when
/proc/<pid>/cmdlineis unreadable),verifyDaemonIdentityreads the flat command line fromps -o args=and tokenized it withsplitCommandLine.psjoins argv with single spaces and never quotes, sosplit into
/usr/bin/node,/Users/me/Library/Application,Support/offckb/build/index.js, ... The "script" token never matched the CLI entry, and the identity check failed closed.Fix
src/util/daemon.ts:commandLineRunsScript(cmdline, expectedScript). It does not guess token boundaries. It tries every space as the executable/script boundary and every later space (or the end) as the end of the script. It matches only when the executable is a Node runtime (exactprocess.execPath, or exactnode/nodejs/node.exebasename) and the script resolves to exactly this installation's CLI entry. Comparison is realpath-normalized as before; it is case-insensitive on Windows and also accepts a quoted executable/script (WindowsCommandLine)./proc) and the start-time (PID-reuse) check are unchanged.Tests:
tests/daemon-command-line.test.ts(new): POSIX and Windows command lines with spaced script and Node paths, quoted and unquoted. Negative cases: foreign script,.bak/-othersuffixes, truncated path,bash/cmd.exehosts, empty line.tests/daemon-locale.test.ts: end-to-endverifyDaemonIdentitythrough thepspath with an unquoted spaced CLI path (accepts), plus a sibling-otherscript (rejects). This test fails ondevelop.Changeset:
.changeset/daemon-stop-spaced-path.md(patch).Before / after
Live, with the built CLI copied into a directory with a space (
/tmp/offckb develop/vs/tmp/offckb fixed/),node --daemonstarted, thennode stop. The box is Linux, so the stop process was run with a--requirepreload that makes/proc/<pid>/cmdlineunreadable. That forces the sameps -o args=path macOS always takes.Still strict (live): with the same
pspath, the fixed install'snode stopstill refuses a daemon started by the other install. The default Linux/procpath also still stops the daemon cleanly.Verification
