Git with broken hash generation to generate collisions between object IDs. Don't use this!

![]() The thread at http://thread.gmane.org/gmane.comp.version-control.git/257392 details problems when applying patches with "git am" in a repository with CRLF line endings. In the example in the thread, the repository originated from "git-svn" so it is not possible to use core.eol and friends on it. Right now, the best option is to use "git am --keep-cr". However, when a patch create new files, the patch application process will reject the new file because it finds a "/dev/null\r" string instead of "/dev/null". The problem is that SMTP transport is CRLF-unsafe. Sending a patch by email is the same as passing it through "dos2unix | unix2dos". The newly introduced CRLFs are normally transparent because git-am strips them. The keepcr=true setting preserves them, but it is mostly working by chance and it would be very problematic to have a "git am" workflow in a repository with mixed LF and CRLF line endings. The MIME solution to this is the quoted-printable transfer enconding. This is not something that we want to enable by default, since it makes received emails horrible to look at. However, it is a very good match for projects that store CRLF line endings in the repository. The only disadvantage of quoted-printable is that quoted-printable patches fail to apply if the maintainer uses "git am --keep-cr". This is because the decoded patch will have two carriage returns at the end of the line. Therefore, add support for base64 transfer encoding too, which makes received emails downright impossible to look at outside a MUA, but really just works. The patch covers all bases, including users that still live in the late 80s, by also providing a 7bit content transfer encoding that refuses to send emails with non-ASCII character in them. And finally, "8bit" will add a Content-Transfer-Encoding header but otherwise do nothing. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Junio C Hamano <gitster@pobox.com> |

//////////////////////////////////////////////////////////////// Git - the stupid content tracker //////////////////////////////////////////////////////////////// "git" can mean anything, depending on your mood. - random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant. - stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang. - "global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room. - "goddamn idiotic truckload of sh*t": when it breaks 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. 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). Many Git online resources are accessible from http://git-scm.com/ including full documentation and Git related tools. 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). To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.org. The mailing list archives are available at http://news.gmane.org/gmane.comp.version-control.git/, http://marc.info/?l=git and other archival sites. The maintainer frequently sends the "What's cooking" reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
