Subject: [PATCH 2/4] Issue 4956 - Automember allows invalid regex, and does
|
|
|
7a6e0a |
not log proper error
|
|
|
7a6e0a |
|
|
|
7a6e0a |
Bug Description: The server was detecting an invalid automember
|
|
|
7a6e0a |
regex, but it did not reject it, and it did not
|
|
|
7a6e0a |
log which regex rule was invalid.
|
|
|
7a6e0a |
|
|
|
7a6e0a |
Fix Description: By properly rejecting the invalid regex will also
|
|
|
7a6e0a |
trigger the proper error logging to occur.
