[jira] [Updated] (METRON-2002) Number of escape backslashes in
REGEXP_MATCH Stellar function is inconsistent
[ https://issues.apache.org/jira/browse/METRON-2002?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Stefan Kupstaitis-Dunkler updated METRON-2002:
----------------------------------------------
Description:
When I want to escape a character in REGEXP_MATCH I need to escape it with 2 backslashes in the Stellar command line and 4 backslashes when you actually deploy it via the Metron config. Ideally it should be only one backslash in both cases, but a consistent behaviour as a starting point and a mention in the docs to escape the escape characters would be sufficient.
Simple example:
* ip_address := '10.10.10.10'`
* This matches on Stellar command line interface: REGEXP_MATCH(ip_address, 10\\.10\\.10\\.10)
* This works when configured for a running topology: REGEXP_MATCH(ip_address, 10\\\\.10\\\\.10\\\\.10)
* Any other amount of slashes in both cases produces an error or no match.
