Jeff King a9990f8ec0 Makefile: turn on NO_MMAP when building with ASan Git often uses mmap() to access on-disk files. This leaves a blind spot in our SANITIZE=address builds, since ASan does not seem to handle mmap at all. Nor does the OS notice most out-of-bounds access, since it tends to round up to the nearest page size (so depending on how big the map is, you might have to overrun it by up to 4095 bytes to trigger a segfault). The previous commit demonstrates a memory bug that we missed. We could have made a new test where the out-of-bounds access was much larger, or where the mapped file ended closer to a page boundary. But the point of running the test suite with sanitizers is to catch these problems without having to construct specific tests. Let's enable NO_MMAP for our ASan builds by default, which should give us better coverage. This does increase the memory usage of Git, since we're copying from the filesystem into heap. But the repositories in the test suite tend to be small, so the overhead isn't really noticeable (and ASan already has quite a performance penalty). There are a few other known bugs that this patch will help flush out. However, they aren't directly triggered in the test suite (yet). So it's safe to turn this on now without breaking the test suite, which will help us add new tests to demonstrate those other bugs as we fix them.

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.adoc to get started, then see Documentation/giteveryday.adoc for a useful minimum set of commands, and Documentation/git-<commandname>.adoc 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.adoc (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 to git+subscribe@vger.kernel.org (see https://subspace.kernel.org/subscribing.html for details). The mailing list archives are available at https://lore.kernel.org/git/, https://marc.info/?l=git and other archival sites.

Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.
