Limit recursion in ap_expr evaluation to avoid unbounded stack usage

2011-11-19T21:58:48+00:00

* evaluate chains of ||, &&, and string concatenation non-recursively
* limit other types of recursion to 20 levels
* avoid some string copies if concatenating more than 2 strings

Do proper length checks in the expression scanner. This allows to remove the

2011-08-13T09:59:43+00:00

8K length limit for expressions. Strings/Regexs in an expression are still
limited to 8K, though.

Add string valued expressions to ap_expr, do some API cleanup

2011-07-02T07:45:00+00:00

- add possibility to have expressions that evaluate to a string and not to
  a boolean value
- modify ap_expr_parse_cmd() interface to support this and make it more
  convenient to use in general
- rename AP_EXPR_FLAGS_* to AP_EXPR_FLAG_* for consistency

Rename ap_expr's typedef names:

2010-12-04T11:22:30+00:00

ap_expr            ->  ap_expr_t
ap_expr_parse_ctx  ->  ap_expr_parse_ctx_t
ap_expr_eval_ctx   ->  ap_expr_eval_ctx_t
ap_expr_lookup_fn  ->  ap_expr_lookup_fn_t
ap_expr_node_op    ->  ap_expr_node_op_e

- add -ipmatch, -str(c)match, -fnmatch, -R operators to ap_expr

2010-11-28T16:35:14+00:00

- allow lookup function to pre-parse string constant arguments 
  (used for subnet masks so far)
- various bug fixes for binary operators
- do strdup() for error messages created on the stack to avoid corruption

ap_expr related fixes/enhancements:

2010-11-21T17:22:26+00:00

- implement regex backreferences and make them available for setting 
  envvars in SetEnvIfExpr
- implement nested function calls in %-syntax: %{func1:%{func2:arg}} 
- actually implement evaluation of concatenation operator (oops...)
- Fix  treating an internal error as success
