## work together
#### message
- err access line response.cpp:169
- g pas fini la gestion de sortie du cgi (comparaison des headers fields pour supprimer les doublons)
- g rendu independantes les fonctions qui parses un message http (requete ou response) dans `parsing_http_message.cpp`
- il y a une erreur importante dans la fonction qui parse les headers d'un message http : ca ne verifie pas si la premier ligne est un header ou la "first line"
#### TODO
- `_is_cgi()` and `_fill_cgi_path()`
- `_cgi_output()` change status in `client->status`
- two cgi tests :
? - a basic form with "name" and "something", that return a html page with that
? - for GET and POST
? - a script called by a file extension in URI
#### output cgi script :
! TODO : change all the '\n' by '\r\n'
! TODO : there is at least one header field followed by '\r\n\r\n' :
- "Content-Type"
- "Location"
- "Status"
! TODO : there is no space between filed name and ":"
! TODO?: handle Location field, either :
- local : start with '/' --> rerun the request with new uri
- client : start with '<scheme>:' --> send back status code 302
-> TODO : there is no field duplicate (resolve conflicts)
-> TODO : if status field, change server status for this one
-> TODO : if no Location field && no Status field -> status code = 200
#### questions
- in client.cpp i fill the port, is there a default one in case it's not in the request ?
- timeout server but still works ?
- path contains double "//" from `Webserv::_get()` in response.cpp
- cgi path ? defined in config ? and root path ? :
- `Client.cpp : fill_script_path()`
- `cgi.cpp : is_cgi()`
- `cgi.cpp : set_env()`
- what if the uri contains a php file, and the config said php must be handled by cgi, but the path to this php in the uri is wrong ?
- is it ok ? `http://my_site.com/cgi-bin/php-cgi` (real path)
- is it ok ? `http://my_site.com/php-cgi` (reconstruct path ?)
- is it ok ? `http://my_site.com/something/php-cgi` (what about 'something' ?)
- is it ok ? `http://my_site.com/something/cgi-bin/php-cgi` (real path with 'something' before ? )
- I don't save the STDIN and STDOUT before dup2 in child process, is it wrong ?
- the response page is received long after the cgi-script is done, why ?
#### notifications
- i changed the Client getters in two categories :
- getters for requests infos : `get_rq_<info>`
- getters for client sides infos : `get_cl_<info>` (such as ip of client)
- i changed the variables in request struct in Client :
- `path` become `uri` (ex. `/path/to/file?var=val`)
- add `abs_path` (ex. `/path/to/file` )
- add `query` (ex. `var=val`)
- the header fields names, as key in map, are stored in lowercase, and getters are case-insensitives

## cgi rfc
[rfc 3875](https://www.rfc-editor.org/rfc/rfc3875)
#### summary :
- the cgi-script will send back at least one header field followed by an empty line
- this header field will be one of three :
- "Content-Type"
- "Location"
- "Status"
- the cgi-script may send back more header fields
- the server must check and modify few things :
- there is no duplicate in headers fields (if there is, resolve conflict)
- there is no space between the field name and the ":"
- the newlines are of form "\r\n", and not "\n" only
- if the location field is not present, then if the status field is not present either, then the status code is 200
- the cgi-script can return a location field, of two types :
- local redirection : start with a "/", the server must answer as if this was the request uri
- client redirection : start with <name-of-cheme>":", the server must send back a status 302 with this uri to the client
- to pass the body-message to the cgi-script, we write it into the temporary fd on which the script read it's standard input
[3.1: server responsabilities](https://www.rfc-editor.org/rfc/rfc3875#section-3.1)
- The server [...] receives the request from the client
- selects a CGI script to handle the request
- converts the client request to a CGI request
- executes the script and converts the CGI response into a response for the client
[3.3: script uri](https://www.rfc-editor.org/rfc/rfc3875#section-3.3)
- the 'Script-URI' [...] MUST have the property that if the client had accessed this URI instead, then the script would have been executed
[4: how the server prepare the cgi requests](https://www.rfc-editor.org/rfc/rfc3875#section-4)
- the cgi receives 2 differents set of informations :
- the request meta-variables (in UNIX, by env variables)
- and the message-body
[4.1: request meta-variables](https://www.rfc-editor.org/rfc/rfc3875#section-4.1)
- a header field that spans multiple lines MUST be merged onto a single line
[4.2: request message-body](https://www.rfc-editor.org/rfc/rfc3875#section-4.2)
- unless defined otherwise, the script access request data by reading stdin
[6: how the response from the script is returned to the server](https://www.rfc-editor.org/rfc/rfc3875#section-6)
- The response comprises 2 parts, separated by a blank line :
- a message-header
- and a message-body
- The message-header contains one or more header fields
- The body may be NULL
[6.2: responses types](https://www.rfc-editor.org/rfc/rfc3875#section-6.2)
- four types of responses :
- document response
- local redirect response
- client redirect response
- client redirect response with document
- document response :
- it must return a Content-Type header field
- a Status-Header field is optional (200 is assumed if omited)
- the server must check the cgi-script output, and modifie it to comply with the protocol version
- local redirect response :
- it must return only a Location field
- it contains a local path URI and query string ('local-pathquery')
- the local path URI must start with a "/"
- the server must generate the response for this local-pathquery
- client redirect response :
- it must return only a Location field
- it contains an absolute URI path, to indicate the client that it should reprocess the request with this URI
- the absolute URI always start with the name of scheme followed by ":"
- the http server must generate a 302 'Found' message
- client redirect response with document
- it must return a Location field with an absolute URI path
- it must return the Status header field, with a value of 302 'Found'
- the server must check the cgi-script output, and modifie it to comply with the protocol version
[6.3: cgi header fields](https://www.rfc-editor.org/rfc/rfc3875#section-6.3)
- whitespace is permitted between the ":" and the field-value
- but not between the field-name and the ":"
- the CGI script can set three differents fields :
- Content-Type
- Location
- Status
- Content-Type :
- if there is a body in the response, a Content-Type field must be present
- if there is no Content-Type, the server must not attempt to determine one
- Location :
- the local URI path must be an absolut path, not a relative path, nor NULL
- the local URI path must, then, start with "/"
- the absolut URI start with "<name-of-scheme>:"
- Status :
- a 3-digit integer code
- 4 standards :
- 200 'OK' indicates success, it's the default value
- 302 'Found' with Location header and response message-body
- 400 'Bad Request' an unknown request format, like missing CONTENT-TYPE
- 501 'Not Implemented' the script received unsupported REQUEST-METHOD
- construction: `Status:400 "explication of the error"\n`
- the cgi-script can return other header fields, concerning the response message
- the server must translate cgi-headers syntax into http-header syntax
- for exemple, newline can be encoded in different ways
- the cgi-script must not return header fields concerning client-side communication
- the server can remove such fields
- (not sure : https://www.rfc-editor.org/rfc/rfc3875#section-6.3.4)
- the server must resolve conflicts between script-header fields and themselves
[6.3: cgi message body](https://www.rfc-editor.org/rfc/rfc3875#section-6.4)
- the server must read it untill EOF
- the server must not modify it, except to convert charset if needed

- do correct handling of special character in url (/rfc2119_files/errata.js.t%C3%A9l%C3%A9chargement -> /rfc2119_files/errata.js.téléchargement)
- handle redirection
- maybe add a "last_action_time" in Client for timeout handling
little global timeout on epoll, like 100ms, then find client that actualy need to timeout
if (actual_time - client.last_action_time > 10000ms){timeout(client)}
- add headers "Date" and "Last-Modified" to response
- change "std::string" to reference "std::string &" in most functions
and add "const" if apropriate.
- http_method en mode binary flags. "std::vector<http_method> allow_methods" -> "unsigned int allow_methods;"
- Dans le parsing, trier les "locations" par ordre de precision.
Compter les "/" dans le chemin, les locations avec le plus de "/" seront en premier dans le vector.
- Il faut vérifier le path de la requête, voir si le serveur est bien censé délivrer cette ressource et si le client y a accès, avant d'appeler le CGI.

Category: Best Current Practice
Key words for use in RFCs to Indicate Requirement Levels
Status of this Memo
This document specifies an Internet Best Current Practices for the
Internet Community, and requests discussion and suggestions for
improvements. Distribution of this memo is unlimited.
Abstract
In many standards track documents several words are used to signify
the requirements in the specification. These words are often
capitalized. This document defines these words as they should be
interpreted in IETF documents. Authors who follow these guidelines
should incorporate this phrase near the beginning of their document:
<span class="Verified-inline-styling" id="inline-499"> The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL <button id="btn_499" target="expand_499" onclick="hideFunction(&quot;expand_499&quot;)">Expand</button>
NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT
RECOMMENDED", "MAY", and "OPTIONAL" in this document are to
be interpreted as described in RFC 2119.</span>

6. Guidance in the use of these Imperatives
Imperatives of the type defined in this memo must be used with care
and sparingly. In particular, they MUST only be used where it is
actually required for interoperation or to limit behavior which has
potential for causing harm <span class="Verified-inline-styling" id="inline-494">(e.g., limiting retransmissions)</span> For <button id="btn_494" target="expand_494" onclick="hideFunction(&quot;expand_494&quot;)">Expand Multiple</button>

In particular, they MUST only be used where it is actually required
for interoperation or to limit behavior which has potential for
causing harm (e.g., limiting retransmisssions) For example, they
must not be used to try to impose a particular method on
implementors where the method is not required for interoperability.

7. Security Considerations
These terms are frequently used to specify behavior with security
implications. The effects on security of not implementing a MUST or
SHOULD, or doing something the specification says MUST NOT or SHOULD
NOT be done may be very subtle. Document authors should take the time
to elaborate the security implications of not following
recommendations or requirements as most implementors will not have
had the benefit of the experience and discussion that produced the
specification.
8. Acknowledgments
The definitions of these terms are an amalgam of definitions taken
from a number of RFCs. In addition, suggestions have been
incorporated from a number of people including Robert Ullmann, Thomas
Narten, Neal McBurnett, and Robert Elz.
