# tea CLI: `comment` blocks on stdin
|
|
|
|
`tea comment <N> --repo <owner>/<repo> "<body>"` **hangs indefinitely** — it blocks reading
|
|
stdin even though the body was supplied as a positional argument. Observed as a 2-minute
|
|
timeout in an agent session; the request never reached the server (no comment was posted).
|
|
|
|
The fix is to close stdin explicitly:
|
|
|
|
```bash
|
|
tea comment 45 --repo jared/cc-os "$(cat body.md)" < /dev/null
|
|
```
|
|
|
|
The identical command with `< /dev/null` appended completed in seconds and posted correctly.
|
|
|
|
## Scope of the behavior — do not over-generalize
|
|
|
|
Only `tea comment` was observed hanging. In the same session, these ran **without**
|
|
`< /dev/null` and returned normally:
|
|
|
|
- `tea issues list --repo ...`
|
|
- `tea issues <N> --repo ...` (view)
|
|
- `tea issues edit <N> --repo ... --add-assignees <user>`
|
|
|
|
So this is **not** a blanket property of every `tea` subcommand. `tea issues create` and
|
|
`tea issues close` were never tested without the guard, so their behavior is unknown.
|
|
|
|
Cheap defensive habit for any agent scripting tea: append `< /dev/null` to tea calls in
|
|
non-interactive contexts. It is harmless where it isn't needed, and it converts a silent
|
|
2-minute hang into a normal completion.
|
|
|
|
## Why it matters
|
|
|
|
An agent scripting Forgejo issue updates will appear to hang with no error and no output.
|
|
The cause is non-obvious (the body *was* provided, so there is no apparent reason to read
|
|
stdin) and the tea docs do not mention stdin behavior for `comment`. Without knowing this,
|
|
the natural next move is to retry the command — which hangs again.
|
|
|
|
Evidence is one reproduction plus one successful retry differing only in the redirect; the
|
|
stdin hypothesis is strong but not proven against tea's source.
