Subject: [PATCH v3] config: add support for http.<url>.* settings
Date: Thu, 11 Jul 2013 14:50:03 -0700 [thread overview]
Message-ID: <9e7edfbc83a7284615af4ca0de39c1b@f74d39fa044aa309eaea14b9f57fe79> (raw)
The <url> value is considered a match to a url if the <url> value
is either an exact match or a prefix of the url which ends on a
path component boundary ('/'). So "https://example.com/test" will
match "https://example.com/test" and "https://example.com/test/too"
but not "https://example.com/testextra".
Longer matches take precedence over shorter matches with
environment variable settings taking precedence over all.
With this configuration:
[http]
useragent = other-agent
noEPSV = true
[http "https://example.com"]
useragent = example-agent
sslVerify = false
[http "https://example.com/path"]
useragent = path-agent
The "https://other.example.com/" url will have useragent
"other-agent" and sslVerify will be on.
The "https://example.com/" url will have useragent
"example-agent" and sslVerify will be off.
The "https://example.com/path/sub" url will have useragent
"path-agent" and sslVerify will be off.
All three of the examples will have noEPSV enabled.
Signed-off-by: Kyle J. McKay <mackyle@gmail.com>

The credentials configuration values already support url-specific
configuration items in the form credential.<url>.*. This patch
adds similar support for http configuration values.
This version of the patch addresses some initial feedback.
