Merge branch 'jc/url-match'

Browse Source 
Allow section.<urlpattern>.var configuration variables to be
treated as a "virtual" section.var given a URL, and use the
mechanism to enhance http.* configuration variables.

This is a reroll of Kyle J. McKay's work.

* jc/url-match:
  builtin/config.c: compilation fix
  config: "git config --get-urlmatch" parses section.<url>.key
  builtin/config: refactor collect_config()
  config: parse http.<url>.<variable> using urlmatch
  config: add generic callback wrapper to parse section.<url>.key
  config: add helper to normalize and match URLs
  http.c: fix parsing of http.sslCertPasswordProtected variable

of common USER_AGENT strings (but not including those like git/1.7.1).
Can be overridden by the 'GIT_HTTP_USER_AGENT' environment variable.
http.<url>.*::
Any of the http.* options above can be applied selectively to some urls.
For a config key to match a URL, each element of the config key is
compared to that of the URL, in the following order:
+
--
. Scheme (e.g., `https` in `https://example.com/`). This field
must match exactly between the config key and the URL.
. Host/domain name (e.g., `example.com` in `https://example.com/`).
This field must match exactly between the config key and the URL.
. Port number (e.g., `8080` in `http://example.com:8080/`).
This field must match exactly between the config key and the URL.
Omitted port numbers are automatically converted to the correct
default for the scheme before matching.
. Path (e.g., `repo.git` in `https://example.com/repo.git`). The
path field of the config key must match the path field of the URL
either exactly or as a prefix of slash-delimited path elements. This means
a config key with path `foo/` matches URL path `foo/bar`. A prefix can only
match on a slash (`/`) boundary. Longer matches take precedence (so a config
key with path `foo/bar` is a better match to URL path `foo/bar` than a config
key with just path `foo/`).
. User name (e.g., `user` in `https://user@example.com/repo.git`). If
the config key has a user name it must match the user name in the
URL exactly. If the config key does not have a user name, that
config key will match a URL with any user name (including none),
but at a lower precedence than a config key with a user name.
--
+
The list above is ordered by decreasing precedence; a URL that matches
a config key's path is preferred to one that matches its user name. For example,
if the URL is `https://user@example.com/foo/bar` a config key match of
`https://example.com/foo` will be preferred over a config key match of
`https://user@example.com`.
+
All URLs are normalized before attempting any matching (the password part,
if embedded in the URL, is always ignored for matching purposes) so that
equivalent urls that are simply spelled differently will match properly.
Environment variable settings always override any matches. The urls that are
matched against are those given directly to Git commands. This means any URLs
visited as a result of a redirection do not participate in matching.
i18n.commitEncoding::
Character encoding the commit messages are stored in; Git itself
does not care per se, but this information is necessary e.g. when

The url data files in this directory contain URLs with characters
in the range 0x01-0x1f and 0x7f-0xff to test the proper normalization
of unprintable characters.
A select few characters in the 0x01-0x1f range are skipped to help
avoid problems running the test itself.
The urls are in test files in this directory rather than being
embedded in the test script for portability.
