Claus Ibsen created CAMEL-24899:
-----------------------------------
Summary: camel-core - a failed reload of the only route file keeps
the previous routes running (restore from the last good definitions, not from
disk)
Key: CAMEL-24899
URL: https://issues.apache.org/jira/browse/CAMEL-24899
Project: Camel
Issue Type: Improvement
Components: camel-core
Reporter: Claus Ibsen
Fix For: 4.23.0
CAMEL-24860 restores the previous routes after a failed reload by loading the
previous sources again from disk, which works when the failing file is not the
only one. When it is the only route file, the good version is gone from disk,
and the app runs without routes until the next successful save, with the log
saying so. In the camel-jbang-mcp stepwise benchmark every HTTP example is one
file: a write that fails to load (an invalid file written with validate=false,
CAMEL-248xx) takes the whole app down for the rest of the step, and the REST
endpoints answer 404 while the model reads the log.
Keep the last successfully loaded route definitions (the model objects, not the
file) per source, and on a failed reload of that source add them back, so the
app keeps answering with the previous version of the file and the log says
"Reload failed ...; the previous routes of <file> are still running".
