dirstateguard: use mktemp-like functionality to generate the backup filenames Previously these were generated with names like: `dirstate.backup.commit.<memory address of dirstateguard>` This could cause problems if two hg commands ran at the same time that used the same memory address, (which is apparently not uncommon if chg is involved), as memory addresses are not unique across processes. This issue was reported in the post-review comments on http://phab.mercurial-scm.org/D9952. Differential Revision: https://phab.mercurial-scm.org/D10504

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.

Notes for packagers

Mercurial ships a copy of the python-zstandard sources. This is used to provide support for zstd compression and decompression functionality. The module is not intended to be replaced by the plain python-zstandard nor is it intended to use a system zstd library. Patches can result in hard to diagnose errors and are explicitly discouraged as unsupported configuration.
