real_pathdup(): fix callsites that wanted it to die on error In 4ac9006f832 (real_path: have callers use real_pathdup and strbuf_realpath, 2016-12-12), we changed the xstrdup(real_path()) pattern to use real_pathdup() directly. The problem with this change is that real_path() calls strbuf_realpath() with die_on_error = 1 while real_pathdup() calls it with die_on_error = 0. Meaning that in cases where real_path() causes Git to die() with an error message, real_pathdup() is silent and returns NULL instead. The callers, however, are ill-prepared for that change, as they expect the return value to be non-NULL (and otherwise the function died with an appropriate error message). Fix this by extending real_pathdup()'s signature to accept the die_on_error flag and simply pass it through to strbuf_realpath(), and then adjust all callers after a careful audit whether they would handle NULLs well.

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 http://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-.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). 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 https://public-inbox.org/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.
The name “git” was given by Linus Torvalds when he wrote the very first version. He described the tool as “the stupid content tracker” and the name as (depending on your mood):
