Subject: [PATCH] journalctl: make sure 'journalctl -f -t unmatched' blocks
|
|
|
803fb7 |
|
|
|
803fb7 |
Previously the following command:
|
|
|
803fb7 |
|
|
|
803fb7 |
$ journalctl -f -t unmatchedtag12345
|
|
|
803fb7 |
|
|
|
803fb7 |
... would block when called with criteria that did not match any
|
|
|
803fb7 |
journal lines. Once log lines appeared that matched the criteria
|
|
|
803fb7 |
they were displayed.
|
|
|
803fb7 |
|
|
|
803fb7 |
Commit 02ab86c732576a71179ce12e97d44c289833236d broke this
|
|
|
803fb7 |
behavior and the journal was not followed, but the command
|
|
|
803fb7 |
exits with '-- No entries --' displayed.
|
|
|
803fb7 |
|
|
|
803fb7 |
This commit fixes the issue.
