Arc Forum | HTTP header case bug

Arc Forum

4 points by tung 5887 days ago | 4 comments

I was using Anarki and playing around with the Arc web server, but I noticed that submitting forms using emacs-w3m produced the error: "Post request without Content-Length." Studying the headers sent by w3m and comparing them to the same sent by Firefox, I traced it back to the parseheader function in srv.arc.

The problem was the case of the HTTP header fields sent by w3m: "Content-length" rather than the "Content-Length" that Arc expected. I checked RFC 2616 (HTTP/1.1), and according to section 4.2, "Field names are case-insensitive." I altered srv.arc to reflect this.

I just pushed the change into the public repo, according to the instructions here: http://arclanguage.org/item?id=3849 . I checked the logs, and there seems to be a couple of extra merge commit messages. Is there any way to avoid that in future? I'm new to git.

NB: I am a total git noob and you shouldn't listen to anything I say.

When I pull I do `git pull --rebase' which avoids the merge commits. I'm not sure what the interactive (-i) switch to git rebase does (I have a good idea though), but the default place to pull from is origin/master (afaik) so they're probably quite similar.

Thanks. The merge log messages are technically accurate, but they seem like the sort of thing that would clutter the history.

Supposedly you can use the "git rebase -i origin/master" command as described in the CONVENTIONS file. It doesn't seem to work on me, however; I get the message "Usage: /usr/bin/git-rebase [-v] [--onto <newbase>] <upstream> [<branch>]"; looking at my online documentation does not reveal a -i option. ^^

You probably need a newer git. People recommend using git HEAD and I haven't had problems with it so far.

  cd ~/src
  git clone git://git.kernel.org/pub/scm/git/git.git
  cd git
  make prefix=$HOME/apps all doc info
  make prefix=$HOME/apps install install-doc install-info
