Subject Re: Additional core functions for mod_lua
Date Mon, 06 Aug 2012 14:31:29 GMT
If no one objects, I'll start moving in some functions to the mod_lua
core, starting with the ones that pertain to obtaining a "static" value
from the request/server, as well as the flush and sendfile function, and
making them part of the request_rec package. This includes the following
(as they will appear when imported):

r:flush() - 		Flushes the output buffer
r:sendfile(filename) -	Sends a file using sendfile if available
r.port - 		the port in use by the request
r.banner - 		the server banner
r.options - 		the Options directive for the request
r.allowoverrides - 	the AllowOverride directive for the request
r.started -		the time the server was (re)started
r.basic_auth_pw	-	the basic auth password, if any was sent
r.limit_req_body -	The current request body limit (or 0 for none)
r.server_built -	The time the server was built
r.is_initial_req -	Whether this is the initial request or a subreq
r.remaining -		The remaining bytes in the request body
r.some_auth_required -  Whether some authorization is/was required
r.server_name -		The server name for the request
r.auth_name -		The realm used (if any) for authorization

This leaves the following functions still in the apache2 package -
If you'd rather see any of them moved to the request_rec package, do say
so - :

apache2.base64_encode -		Encode a string in base64
apache2.base64_decode -		Decode a base64 string
apache2.md5 -			Generate an MD5 hash
apache2.sha1 -			Generate a SHA-1 hash
apache2.escape -		URL-escape a string
apache2.unescape -		unescape an URL-encoded string
apache2.mpm_query -		Query the MPM for information
apache2.expr -			Evaluate an ap_expr string
apache2.scoreboard_process -	Query the process scoreboard
apache2.scoreboard_worker -	Query a worker scoreboard
apache2.clock -			Returns the current time in microseconds
apache2.requestbody -		Fetches (or saves) the request body
apache2.dbopen -		Opens up a database connection
				(supports both apr_dbd and mod_dbd)
apache2.add_input_filter -	Adds an input filter to the request
apache2.module_info - 		Queries the server for info about a mod
apache2.loaded_modules -	Lists all the loaded modules
apache2.runtime_dir_relative -	Returns a path relative to runtime dir
apache2.server_info -		Returns information about the executable
apache2.set_document_root -	Sets the document root for a request
apache2.add_version_component - Adds a version component
apache2.os_escape_path -	Escapes a path as a URL
apache2.strcmp_match -		Does a strcmp_match (the foo* kind)
apache2.set_keepalive -		Set the keepalive status for a request
apache2.make_etag - 		Creates an entity tag
apache2.send_interim_response - Sends an interim response (or does it?)
apache2.custom_response - 	Sets a custom response for an error msg
apache2.exists_config_define -	Query whether a define was made
apache2.state_query -		Queries the server for state info
apache2.stat -			Stats a file and returns info as a table
apache2.regex -			Evaluates regular expressions
apache2.sleep -			Sleeps for N seconds (accepts floats)
apache2.get_server_name_for_url Servername for URL purposes

Full descriptions and examples are still available at if you need more info.

If anyone has any other requests for internal functions they'd like to
use in mod_lua, just speak up, I'm always happy to include more
