1. EuMVC:Dealing with favicon request

I'm getting an error using Eu-MVC:

c:\eu_include\mvc\include\mvc\app.e:604 in function handle_request()  
subscript value 5 is out of bounds, reading from a sequence of length 4 - in assignment to 'func_id'  
    path_info = {47'/',102'f',97'a',118'v',105'i',99'c',111'o',110'n',46'.', 
105'i',99'c',111'o'} 
    request_method = {71'G',69'E',84'T'} 
    query_string = {} 
    exit_code = 0 
    route_found = 0 
    default_route = 0 
    response = {} 
    patterns = { 
                 {47'/',115's',117'u',98'b',99'c',97'a',108'l',99'c'}, 
                 {47'/',115's',117'u',98'b',99'c',97'a',108'l',99'c',47'/',

117'u',116't',104'h'}, 
                 {94'^',47'/',46'.',43'+',36'$'}, 
                 {47'/'} 
               } 
    candidates = { 
                   {94'^',47'/',46'.',43'+',36'$'} 
                 } 
    i = 4 
    pattern = <no value> 
    i = 1 
    pattern = {94'^',47'/',46'.',43'+',36'$'} 
    path = {42'*'} 
    name = {117'u',110'n',107'k',110'n',111'o',119'w',110'n'} 
    vars = {} 
    methods = 21 
    func_id = <no value> 
    matches = <no value> 
    request = <no value> 
    pattern = <no value> 
    path = <no value> 
    name = <no value> 
    vars = <no value> 
    methods = <no value> 
    func_id = <no value> 
    request = <no value> 

What's the fix for this?

c:\eu_include\mvc\include\mvc\app.e:604 in function handle_request()  
subscript value 5 is out of bounds, reading from a sequence of length 4 - in assignment to 'func_id'  

I figured that'd be the case!

The problem is this function in my app:

function unknown(object request) 
sequence url = map:get(request,"PATH_INFO") 
    map response = map:new() 
	addHomePageVars(response) 
	map:put(response, "error", "Unknown path: " & map:get(request,"PATH_INFO")) 
    return redirect( url_for("index", response ) ) 
end function 
app:route("*", "unknown") 

It's supposed to be a catch-all for unknown paths. I guess I need a different approach...

Dang. That ain't right.

Sorry, I meant "Yes, it gives you the latest code." It's just zipping whatever you'd get with a git clone.

By default it will return a 404 error with the message "The requested URL was not found on this server."

If you have a default route handler set (the "*" catch-all) then it will call up that handler and you'll need to respond accordingly.

You can see that behavior here: https://github.com/OpenEuphoria/euphoria-mvc/blob/master/include/mvc/app.e#L708

And if you're running through a real web server like Nginx or Apache, then that's beyond the scope of EuMVC and it may serve up static files depending on your configuration, so be careful.

Well like I said, that depends entirely on your configuration. Here is the example .htaccess configuration from the EuMVC project:

# Add CGI handler for index.esp 
AddHandler cgi-script .esp 
DirectoryIndex index.esp 
Options +ExecCGI 
 
# Send all non-existent paths to index.esp 
RewriteEngine On 
RewriteCond %{REQUEST_FILENAME} !-f 
RewriteRule ^(.*)$ index.esp/$1 [L,NS] 
 
# Deny access to these file patterns 
<Files ~ ".(cfg|err|edb)$"> 
    Deny from all 
</Files> 

Any files that do exist will get served up when they're requested, unless denied by the <Files> block.

Any files that don't exist will be sent through index.esp. Since index.esp is running EuMVC, it will return a final 404 error if it cannot find a matching route for the requested path.

I'd recommend putting important files outside of the DocumentRoot altogether, especially any local database files you might be using. Then just access them using relative paths instead.

General "CGI best practices" are beyond the scope of EuMVC and it's worth reading through the Apache manual and doing some manual testing to ensure you understand how it all works.
