index: remove side-effect from failed nt_new() As pointed out by Yuya in the review of D4108, if realloc() fails, we would end up with an invalid nodetree instance (with nt->nodes set to NULL), which means that if it was later accessed again it would likely segfault. It's probably unlikely that much else happens in the process if it ran out memory, but we should of course do our best to handle it. This patch makes it so we don't update the nodetree in this case.

Mercurial

Mercurial is a fast, easy to use, distributed revision control tool for software developers.

Basic install:

$ make            # see install targets
$ make install    # do a system-wide install
$ hg debuginstall # sanity-check setup
$ hg              # see help

Running without installing:

$ make local      # build for inplace usage
$ ./hg --version  # should show the latest version

See https://mercurial-scm.org/ for detailed installation instructions, platform-specific notes, and Mercurial user information.
