Spiffy handlers which add support for CGI and derivatives (currently only FastCGI).
Support for the FastCGI server-side specification. This allows you to run FastCGI client processes like Rails or PHP as backends to be accessed from Spiffy.
You can load it via the fcgi-handler module:
The fcgi-handler module exports two procedures:
- fcgi-handler app-name #!key (continue #f)procedure
TODO: Document this.
- fcgi-register-application name role filename socket prespawn maxspawnprocedure
TODO: Document this.
Constants that store role identifiers for use in fcgi-register-application.
This egg includes support for the old-fashioned CGI/1.1 protocol, as specified by RFC 3875. It includes a few workarounds required for PHP as well.
You can load it via the cgi-handler module:
All request headers will be passed as environment variables to the CGI program, prefixed with "HTTP_", and converted to uppercase, with hyphens ("-") replaced by an underscore ("_"). The CGI program will receive the request body in unparsed form from stdin and should write a complete HTTP response to stdout. Any headers that are missing but required for HTTP will be added by Spiffy. For more info on how a CGI script is called, consult the spec.
The AUTH_TYPE and REMOTE_USER environment variables are currently not set during invocation of CGI subprocesses. The REMOTE_IDENT environment variable is not and never will be supported.
The cgi-handler module exports two procedures:
- cgi-handler filename #!optional interpreterprocedure
The cgi handler simply calls CGI scripts. It is assumed the requested file is executable if no interpreter is given. (If used as a regular handler, it will only receive the filename). If the filename is a relative path, it is assumed to be relative to (root-path). It's safer to store your scripts outside the docroot, though!
- cgi-handler* #!optional interpreterprocedure
The CGI handler can be configured with the following parameters:
- cgi-default-environment #!optional env-alistprocedure
The environment variables that should be in the default environnment of every CGI program. Variables like SCRIPT_NAME will be added dynamically to the end of this alist.
(("GATEWAY_INTERFACE" . "CGI/1.1"))
- Add support for both CHICKEN 4 and CHICKEN 5 from the same codebase.
- Avoid "httpoxy" attack by not converting a Proxy header to a HTTP_PROXY environment variable (CVE-2016-6286).
- Reduce copy/pasted code between FCGI and CGI by putting it in one file.
- Do not use stock intarweb header parser for parsing CGI response: this was made more strict so CRLF was required, instead of just the LF which CGI wants.
- Remove dependency on the regex egg.
- Rework the FCGI header parsing to fix spurious line break issues.
- Support the non-blocking sockets produced by the socket egg in version 0.2.3 and later.
- Include the query string, as well as the path, in REQUEST_URI.
- Initial release of FastCGI module and moved CGI module from Spiffy to this egg.
