How use [rewrite_rules][conditions] with REQUEST_FILENAME in .ini?

Standalone code, or other way to reproduce the problem

I expected to ignore only files, the folders would still go through rewrite (note that the ini is "commented"):

hhvm.virtual_host[default][check_existence_before_rewrite] = false

;hhvm.virtual_host[default][rewrite_rules][common][conditions][-d][pattern] = "%{REQUEST_FILENAME}"
;hhvm.virtual_host[default][rewrite_rules][common][conditions][-d][type] = request
;hhvm.virtual_host[default][rewrite_rules][common][conditions][-d][negate] = true

hhvm.virtual_host[default][rewrite_rules][common][conditions][-f][pattern] = "%{REQUEST_FILENAME}"
hhvm.virtual_host[default][rewrite_rules][common][conditions][-f][type] = request
hhvm.virtual_host[default][rewrite_rules][common][conditions][-f][negate] = true

hhvm.virtual_host[default][rewrite_rules][common][pattern] = "(.*)"
hhvm.virtual_host[default][rewrite_rules][common][to] = "index.php"
hhvm.virtual_host[default][rewrite_rules][common][qsa] = true

This is an "illustrative" code, I believe that -d and -f flags aren't supported.

Expected result

Ignore rewrite_rules from form pattern

I reviewed the documentation, but only found the "check_existence_before_rewrite", Is there any way to check for the existence of specific files using proxygen before applying rewrite?

According to the docs site:

    RewriteRules {
      * {
        pattern = regex pattern same as Apache's
        to = target format same as Apache's
        qsa = false
        redirect = 0 (default: off) | 302 | 301 | other status code

        conditions {
          * {
            pattern = regex pattern to match
            type = host | request
            negate = false
          }
        }
      }
    }

The position you are putting the flag in is a glob. The name you assign does not get used. The whole point is to allow for a vector of conditions. In this case you are just labeling the entries in the vector as -d, and -f.

There is not support for those flags.

@mofarrell it's pseudo-code, is only a example :)

I would just like to know if there is any way to check the file exists within [conditions].

[mofarrell]

Not currently. The only option available for related to that is the global one.
Adding logic to support that shouldn't be too hard. The rewrite system is pretty self contained.
