Subject: [PATCH] fsmonitor: query watchman with right valid json
Date: Tue, 7 Jun 2022 09:54:25 +0200 [thread overview]
Message-ID: <20220607075425.39510-1-sluongng@gmail.com> (raw)
In rare circumstances where the current git index does not carry the
last_update_token, the fsmonitor v2 hook will be invoked with an
empty string which would caused the final rendered json to be invalid.
["query", "/path/to/my/git/repository/", {
"since": ,
"fields": ["name"],
"expression": ["not", ["dirname", ".git"]]
}]
Which will left user with the following error message
> git status
failed to parse command from stdin: line 2, column 13, position 67: unexpected token near ','
Watchman: command returned no output.
Falling back to scanning...
Hide the "since" field in json query when "last_update_token" is empty.
