A cross-platform library for building Gemini servers

mehari's Issues

IAMISSAM es-tu là c'est long une heure

Support CGI for Mehari_eio

Waiting for ocaml-multicore/eio#330

Middleware

Functorize implementation of functions related to Gemini protocol

• to avoid semantic differences (like for Mehari_*.load_cert)

Special route path

Perform more check on client request

According to specification:

In particular, the authority component is allowed and required, but its userinfo subcomponent is NOT allowed. The host subcomponent is required. The port subcomponent is optional, with a default value of 1965. The path, query and fragment components are allowed and have no special meanings beyond those defined by the generic syntax. An empty path is equivalent to a path consisting only of "/". Spaces in paths should be encoded as %20, not as +.

is a UTF-8 encoded absolute URL, including a scheme, of maximum length 1024 bytes. The request MUST NOT begin with a U+FEFF byte order mark.

Client certificate in request

Timeout when parsing client request in `Mehari_eio`

Allow delayed response in `Mehari.response_raw`

Allow proxy

Currently, server only respond to request containing one of its own hostnames. So proxying is not allowed.

CGI

Virtual hosts router.

Make `Mehari_mirage` work again.

Improve logging related features

Inspired by https://aantron.github.io/dream/#logging.

Pull out some convenient functions from `Dream`

Such as:

• https://aantron.github.io/dream/#val-pipeline
• https://aantron.github.io/dream/#val-no_route
• https://aantron.github.io/dream/#val-no_middleware

Improve static implementation

• Add a "go to parent directory" feature.

Support Fast CGI

Rate limit doc

Static

Support `Mehari.stream` in `Mehari_mirage`

flush labeled is simply ignored by function which writes on socket.

Maybe redesign delayed stream body, inspired by https://aantron.github.io/dream/#type-stream.

Branding.

Remove dependence to Lwt_stream in Mehari pure lib

Replace it by Seq for crossplatform

Directory listing

• Mehari_eio implementation
• Mehari_lwt_unix implementation

Catch `Eio.Exn.Io`.

This exception is introduced in eio 0.7 which is not yet available on opam.

Line 105 in a7ac1da

(*| Eio.Exn.Io (Eio.Net.E (Connection_reset _), _) ->

Check well encoded UTF-8 in client request

Remove zed as dependence and use a less hacky solution.

Remove UNIX syscall in mirage-eio

Replace mirage-clock-unix by mirage-clock-eio when it becomes available.

More accurate URL check

• Filter out scheme other than gemini
• Filter out url which have wrong host

`Gemtext.to_string` only working for the first line.

Gemtext.quote "text1\ntext2\ntext3" |> Gemtext.to_string

returns

>text1
text2
text3

Malformed header

Rename `Mehari_eio` to `Mehari_eio_unix`

To prevent Mirage OS runtime compatibility in the future.

Add `Mehari.target`

As a shortcut for Mehari.uri req |> Uri.path.

Log

No mime

Configurable default response

Fastest Gemtext parsing

Performance of Mehari.Gemtext.of_string can be improved. Currently, the parser uses regex which is not very efficient.

• Use a buffer
• Speed up parser by removing regex ?

Allow flush in long live TCP stream

SNI

Support gemini mime inference

Add support for .gmi file mime inference in Mehari.from_filename.

Rate limiter

Handle more Eio exception
