Is there a reason why the httpstatus test is case sensitive?

"URLs in general are case-sensitive (with the exception of machine names).
There may be URLs, or parts of URLs, where case doesn't matter, but
identifying these may not be easy. Users should always consider that URLs
are case-sensitive."

Yesterday, I crashed xymonnet by doing a copy/paste into an httpstatus
test. I eventually figured out what was wrong.

This syntax is good:
    0.0.0.0  foo.com   # httpstatus;http://foo.com/index.html;401
This syntax is bad:
    0.0.0.0  foo.com   # httpstatus;HTTP://foo.com/index.html;401

The man page for hosts.cfg doesn't say anything about required or
supported casing. Is there some reason why xymonnet shouldn't be able to
handle mixed-case protocol names in the URLs provided?

John,


Can't think of any... Case preservation should be done for the path, but
the protocol is irrelevant there. https://www.ietf.org/rfc/rfc1738.txt
calls it out as a 'should', so it seems like a bug (I believe parse_url()
in lib/url.c). I'll roll this in.

Curious, did you get any sort of error log output before it went down?
Aside from case-insensitive matching, it's an indication we're not doing
sufficient error checking later on somewhere.

Yes. I received:
 2015-03-31 14:39:34 Unknown URL scheme 'HTTP' in URL 'HTTP://foo.com:9080
'

which looks like it comes from lib/url.c following a case-sensitive match
of startp against a list of possible types.

Thanks for your quick attention.
