--------------------------------
Summary: [FILEINSTALL] Prevent duplicate *.cfg files in
subdirectories from corrupting live OSGi configurations- #544
Key: FELIX-6855
URL: https://issues.apache.org/jira/browse/FELIX-6855
Project: Felix
Issue Type: Bug
Components: File Install
Reporter: Jefiya MJ
When `felix.fileinstall.subdir.mode = recurse` is active, FileInstall scans all
subdirectories under the watched root and registers every matching file as an
OSGi Configuration object.
Both `setConfig()` and `deleteConfig()` derive the ConfigurationAdmin PID from
the filename alone via `parsePid(f.getName())`, discarding the directory path
entirely. This means any two files with the same name —
regardless of where they sit in the directory tree — resolve to the same PID.
Consequences:
- If a file with the same name as a live configuration is copied into a
subdirectory, `setConfig()` overwrites the live configuration's
`felix.fileinstall.filename` property with the duplicate file's URI, silently
stealing ownership.
- When the duplicate file is later deleted, `deleteConfig()` resolves the same
PID and calls `config.delete()` on the live Configuration object — removing it
from ConfigurationAdmin even though the original physical file was never
touched. Dependent OSGi services stop immediately and cannot restart.
