Summary: Spring Boot Camel SFTP Consumer: How to apply setgid
permissions to all directories created by SFTP autoCreate?
Key: CAMEL-24877
URL: https://issues.apache.org/jira/browse/CAMEL-24877
Project: Camel
Issue Type: Improvement
Components: camel-ftp, camel-sftp
Reporter: samhithae
Fix For: 4.18.3
We are using Apache Camel SFTP consumer in Spring boot application to poll
files from a remote directory and create nested directory structures.
When using _*{{chmodDirectory}}*_ in the camel uri for consumption with setgid
bit (e.g., {{2770}} or {{{}2775{}}}), Camel only applies the setgid bit to the
final endpoint directory, but not to intermediate directories created during
the path build process.
h2. Expected Behavior:
All created directories should have the specified permissions, including the
setgid bit.
h2. Actual Behavior:
* Final directory ({{{}/test/tmp{}}}) gets full {{2770}} permissions
* Intermediate directory ({{{}/test{}}}) gets only {{770}} (setgid bit
ignored)
h5. Camel SFTP URI: consumer-test directory is already created, expecting sftp
consumer to create test/tmp sub-directories

{{## Actual Permissions drwxrwx--- 770 /consumer-test/test ← Missing setgid!

{{{}{}}}What I've Tried:{{{}{}}}
{code:java}
1. `chmodDirectory=2770` — setgid only applied to final dir
2. `chmodDirectory=2775` — same issue
3. `chmodDirectory=775` — works on both dirs (but no setgid)
4. `stepwise=true` + `chmodDirectory=2770` — same issue{code}
{{{}{}}}{{{}{}}}
How to make this Camel sftp consumer to apply setgid permissions to all
subdirectories instead of just the final directory?
