RequestLogger generates unparseable log entries
-----------------------------------------------
Key: WICKET-3919
URL: https://issues.apache.org/jira/browse/WICKET-3919
Project: Wicket
Issue Type: Bug
Components: wicket-core
Affects Versions: 1.5-RC5.1
Reporter: Martijn Dashorst
The current (default) request logger generates logs that are not parsable by
automated tools. The identifiers and values give many collisions with keywords,
making it impossible to create an efficient ANTLR parser/lexer for it.
A couple of observations:
- the log is not parsable due to inconsistent logging of log parts. For
example [ResourceStreamRequestTarget[[]] generates an unbalanced number of
brackets
- some parts are joined by ',' and others are joined by ', ' (notice the extra
whitespace)
- it is not possible to retrieve parts of the logs because keywords,
identifiers and values share the same namespace. A page parameter with name
'event' would choke a LL(x) parser since the lexer will render a keyword
instead of a value
Possible solutions:
- fix the current format to become consistent and parsable, by surrounding
identifiers and values with single quotes and escaping single quotes inside the
identifiers and values, and fixing other issues
- render JSON instead of the current format (in my opinion best done in a
separate JSonRequestLogger)
- ???
