Ragel 6.10 on FreeBSD 12.4 amd64 complains and fails on this, yet the same
Ragel version on Debian 11.x i386 and amd64 never has. I suspect this can
fix compatibility on s390x, arm64, armel, and armhf Debian builds:

* [ANN] unicorn 5.2.0 - Rack HTTP server for fast clients and *nix

unicorn is an HTTP server for Rack applications designed to only serve
fast clients on low-latency, high-bandwidth connections and take
advantage of features in Unix/Unix-like kernels. Slow clients should
only be served by placing a reverse proxy capable of fully buffering
both the the request and response in between unicorn and slow clients.

Changes:
Most notably, this release allows us to support requests with
lines delimited by LF-only, as opposed to the standard CRLF
pair and allowed by RFC 2616 sec 19.3.
Thanks to Mishael A Sibiryakov for the explanation and change:
https://bogomips.org/unicorn-public/1476954332.1736.156.camel@junki.org/
Thanks to Let's Encrypt, the website also moves to HTTPS
<https://bogomips.org/unicorn/> to improve reader privacy. The
"unicorn.bogomips.org" subdomain will be retired soon to reduce
subjectAltName bloat and speed up certificate renewals.
There's also the usual round of documentation and example
updates, too.

It's a good desire :) I'll comply next time.

Ah, that's an old test from Mongrel, probably not worth fixing;
just trying to keep new code cleaner.

Thanks for that useful explanation. Aside from the unnecessary,
"Hi all,", that is an informative commit message which justifies
the usefulness of that patch.

Unfortunately, the commit message in your git repo is lacking.
I've used the text at the top of your email.

Eeep, Evolution does some strange things with formatting
whitespaces. It looks like instructions for making it nicer are
in the Linux kernel:

I expect code to be wrapped at 80 lines or less. Fixed locally.
(I need big fonts, even 80 is a compromise, I really prefer 64)
Anyways, pushed to the "rfc2616-sec19.3" branch.
I've also uploaded a prerelease 5.1.0.4.gd5fbb to RubyGems
for folks without Ragel.
gem install --pre unicorn -v 5.1.0.4.gd5fbb
Anything else? Expect a 5.2.0 release in a few days or so.
Thanks.

Hi all.
We're implementing client certificate authentication with nginx and
unicorn.
Nginx configured in the following way:
proxy_set_header X-SSL-Client-Cert $ssl_client_cert;
When client submits certificate and nginx passes it to the unicorn,
unicorn responds with 400 (Bad Request). This caused because nginx
doesn't use "\r\n" they using just "\n" and multilne headers is failed
to parse (I've added test).
Accorording to RFC2616 section 19.3:
https://www.w3.org/Protocols/rfc2616/rfc2616-sec19.html#sec19.3
"The line terminator for message-header fields is the sequence CRLF.
However, we recommend that applications, when parsing such headers,
recognize a single LF as a line terminator and ignore the leading CR."
CRLF changed to ("\r\n" | "\n")

76de05720f6be758f8b41b1f
PS: Googling "nginx unicorn ssl_client_cert" shows the problem.
