    I upgraded to 2017.2.2 and have been bitten by the lack of mercurial largefiles support on the server, which I only found out here…

    Now I am getting this error
    Failed to collect changes, error: ‘hg –config ui.interactive=False pull –config extensions.progress= –config “progress.format=topic number” –config progress.delay=0 –config progress.assume-tty=True \\repopath’ command failed.
    stderr: abort: unknown repository format: requires features ‘largefiles’ (upgrade Mercurial)!

    It appears this is a security concern but there are no details and now I can’t build anything.

    this change was described in upgrade notes: We disabled custom configs on TeamCity server because it allows arbitrary code execution. Please add the following:

    largefiles =

    to the ~/.hgrc of the user who runs TeamCity server.
