Lint for and fix the three manual pages that were missing the standard
"Part of the linkgit:git[1] suite" end section.
We only do this for the man[157] section documents (we don't have
anything outside those sections), not files to be included,
howto *.txt files etc.
We could also add this to the existing (and then renamed)
lint-gitlink.perl, but I'm not doing that here.
Obviously all of that fits in one script, but I think for something
like this that's a one-off script with global variables it's much
harder to follow when a large part of your script is some if/else or
keeping/resetting of state simply to work around the script doing two
things instead of one.
Especially because in this case this script wants to process the file
as one big string, but lint-gitlink.perl wants to look at it one line
at a time. We could also consolidate this whole thing and
t/check-non-portable-shell.pl, but that one likes to join lines as
part of its shell parsing.
So let's just add another script, whole scaffolding is basically:
use strict;
use warnings;
sub report { ... }
my $code = 0;
while (<>) { ... }
exit $code;
We'd spend more lines effort trying to consolidate them than just
copying that around.

NAME

----
|
|
git-credential - Retrieve and store user credentials
|
|
|
|
SYNOPSIS
|
|
--------
|
|
------------------
|
|
git credential <fill|approve|reject>
|
|
------------------
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
Git has an internal interface for storing and retrieving credentials
|
|
from system-specific helpers, as well as prompting the user for
|
|
usernames and passwords. The git-credential command exposes this
|
|
interface to scripts which may want to retrieve, store, or prompt for
|
|
credentials in the same manner as Git. The design of this scriptable
|
|
interface models the internal C API; see credential.h for more
|
|
background on the concepts.
|
|
|
|
git-credential takes an "action" option on the command-line (one of
|
|
`fill`, `approve`, or `reject`) and reads a credential description
|
|
on stdin (see <<IOFMT,INPUT/OUTPUT FORMAT>>).
|
|
|
|
If the action is `fill`, git-credential will attempt to add "username"
|
|
and "password" attributes to the description by reading config files,
|
|
by contacting any configured credential helpers, or by prompting the
|
|
user. The username and password attributes of the credential
|
|
description are then printed to stdout together with the attributes
|
|
already provided.
|
|
|
|
If the action is `approve`, git-credential will send the description
|
|
to any configured credential helpers, which may store the credential
|
|
for later use.
|
|
|
|
If the action is `reject`, git-credential will send the description to
|
|
any configured credential helpers, which may erase any stored
|
|
credential matching the description.
|
|
|
|
If the action is `approve` or `reject`, no output should be emitted.
|
|
|
|
TYPICAL USE OF GIT CREDENTIAL
|
|
-----------------------------
|
|
|
|
An application using git-credential will typically use `git
|
|
credential` following these steps:
|
|
|
|
1. Generate a credential description based on the context.
|
|
+
|
|
For example, if we want a password for
|
|
`https://example.com/foo.git`, we might generate the following
|
|
credential description (don't forget the blank line at the end; it
|
|
tells `git credential` that the application finished feeding all the
|
|
information it has):
|
|
|
|
protocol=https
|
|
host=example.com
|
|
path=foo.git
|
|
|
|
2. Ask git-credential to give us a username and password for this
|
|
description. This is done by running `git credential fill`,
|
|
feeding the description from step (1) to its standard input. The complete
|
|
credential description (including the credential per se, i.e. the
|
|
login and password) will be produced on standard output, like:
|
|
|
|
protocol=https
|
|
host=example.com
|
|
username=bob
|
|
password=secr3t
|
|
+
|
|
In most cases, this means the attributes given in the input will be
|
|
repeated in the output, but Git may also modify the credential
|
|
description, for example by removing the `path` attribute when the
|
|
protocol is HTTP(s) and `credential.useHttpPath` is false.
|
|
+
|
|
If the `git credential` knew about the password, this step may
|
|
not have involved the user actually typing this password (the
|
|
user may have typed a password to unlock the keychain instead,
|
|
or no user interaction was done if the keychain was already
|
|
unlocked) before it returned `password=secr3t`.
|
|
|
|
3. Use the credential (e.g., access the URL with the username and
|
|
password from step (2)), and see if it's accepted.
|
|
|
|
4. Report on the success or failure of the password. If the
|
|
credential allowed the operation to complete successfully, then
|
|
it can be marked with an "approve" action to tell `git
|
|
credential` to reuse it in its next invocation. If the credential
|
|
was rejected during the operation, use the "reject" action so
|
|
that `git credential` will ask for a new password in its next
|
|
invocation. In either case, `git credential` should be fed with
|
|
the credential description obtained from step (2) (which also
|
|
contain the ones provided in step (1)).
|
|
|
|

|
|
INPUT/OUTPUT FORMAT
|
|
-------------------
|
|
|
|
`git credential` reads and/or writes (depending on the action used)
|
|
credential information in its standard input/output. This information
|
|
can correspond either to keys for which `git credential` will obtain
|
|
the login information (e.g. host, protocol, path), or to the actual
|
|
credential data to be obtained (username/password).
|
|
|
|
The credential is split into a set of named attributes, with one
|
|
attribute per line. Each attribute is specified by a key-value pair,
|
|
separated by an `=` (equals) sign, followed by a newline.
|
|
|
|
The key may contain any bytes except `=`, newline, or NUL. The value may
|
|
contain any bytes except newline or NUL.
|
|
|
|
In both cases, all bytes are treated as-is (i.e., there is no quoting,
|
|
and one cannot transmit a value with newline or NUL in it). The list of
|
|
attributes is terminated by a blank line or end-of-file.
|
|
|
|
Git understands the following attributes:
|
|
|
|
`protocol`::
|
|
|
|
The protocol over which the credential will be used (e.g.,
|
|
`https`).
|
|
|
|
`host`::
|
|
|
|
The remote hostname for a network credential. This includes
|
|
the port number if one was specified (e.g., "example.com:8088").
|
|
|
|
`path`::
|
|
|
|
The path with which the credential will be used. E.g., for
|
|
accessing a remote https repository, this will be the
|
|
repository's path on the server.
|
|
|
|
`username`::
|
|
|
|
The credential's username, if we already have one (e.g., from a
|
|
URL, the configuration, the user, or from a previously run helper).
|
|
|
|
`password`::
|
|
|
|
The credential's password, if we are asking it to be stored.
|
|
|
|
`url`::
|
|
|
|
When this special attribute is read by `git credential`, the
|
|
value is parsed as a URL and treated as if its constituent parts
|
|
were read (e.g., `url=https://example.com` would behave as if
|
|
`protocol=https` and `host=example.com` had been provided). This
|
|
can help callers avoid parsing URLs themselves.
|
|
+
|
|
Note that specifying a protocol is mandatory and if the URL
|
|
doesn't specify a hostname (e.g., "cert:///path/to/file") the
|
|
credential will contain a hostname attribute whose value is an
|
|
empty string.
|
|
+
|
|
Components which are missing from the URL (e.g., there is no
|
|
username in the example above) will be left unset.
