Unable to serve files with embedded new line

[Dialga]

A file name with embedded new lines will return as "File not found:" on the web server.
Miniserve was also not able to serve the file, python http.server, php -S and darkhttpd were able to.

Thanks for reporting.

If a file contains an embedded newline, like index.md containing some text, then a blank line and then some text, then serving the file works.

Do you have an example of serving a file where the filename contains a newline? Normally, filenames does not and should not contain newlines.

Please help me understand the isssue, with steps to reproduce the issue, if you could. Thanks.

Sure thing, transcript as follows:

$ echo hi > 'new'$'\n''file'
$ mkdir 'hi'$'\n''world'$'\n'
$ echo hi > 'hi'$'\n''world'$'\n/file'$'\n'name''
$ algernon . 127.0.0.1:8080 -p

It appears the directory listing does not encode the urls.

If I manually url encode the link, I can view the file.

Same with visiting the directory.
