Johannes Schindelin 7725b8100f credential: sanitize the user prompt When asking the user interactively for credentials, we want to avoid misleading them e.g. via control sequences that pretend that the URL targets a trusted host when it does not. While Git learned, over the course of the preceding commits, to disallow URLs containing URL-encoded control characters by default, credential helpers are still allowed to specify values very freely (apart from Line Feed and NUL characters, anything is allowed), and this would allow, say, a username containing control characters to be specified that would then be displayed in the interactive terminal prompt asking the user for the password, potentially sending those control characters directly to the terminal. This is undesirable because control characters can be used to mislead users to divulge secret information to untrusted sites. To prevent such an attack vector, let's add a `git_prompt()` that forces the displayed text to be sanitized, i.e. displaying question marks instead of control characters. Note: While this commit's diff changes a lot of `user@host` strings to `user%40host`, which may look suspicious on the surface, there is a good reason for that: this string specifies a user name, not a <username>@<hostname> combination! In the context of t5541, the actual combination looks like this: `user%40@127.0.0.1:5541`. Therefore, these string replacements document a net improvement introduced by this commit, as `user@host@127.0.0.1` could have left readers wondering where the user name ends and where the host name begins.

Git - fast, scalable, distributed revision control system

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.

Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.

Please read the file INSTALL for installation instructions.

Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.

See Documentation/gittutorial.txt to get started, then see Documentation/giteveryday.txt for a useful minimum set of commands, and Documentation/git-<commandname>.txt for documentation of each command. If git has been correctly installed, then the tutorial can also be read with man gittutorial or git help tutorial, and the documentation of each command with man git-<commandname> or git help <commandname>.

CVS users may also want to read Documentation/gitcvs-migration.txt (man gitcvs-migration or git help cvs-migration if git is installed).

The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission and Documentation/CodingGuidelines).

Those wishing to help with error message, usage and informational message string translations (localization l10) should see po/README.md (a po file is a Portable Object file that holds the translations).

To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.org (not the Git list). The mailing list archives are available at https://lore.kernel.org/git/, http://marc.info/?l=git and other archival sites.
