I'm going to help you ensure your Mercurial is configured for optimal
development on Mozilla projects.

If your environment is missing some recommended settings, I'm going to prompt
you whether you want me to make changes: I won't change anything you might not
want me changing without your permission!

If your config is up-to-date, I'm just going to ensure all 3rd party extensions
are up to date and you won't have to do anything.

To begin, press the enter/return key.

Error running mach:

The error occurred in code that was called by the mach command. This is either
a bug in the called code itself or in the way that mach is calling it.

If filing a bug, please include the full output of mach, including this error
message.

The details of the failure are as follows:

Expected results:

It should help configuring mercurial automatically without any problem.

Comment 1

[Gregory Szorc [:gps]]

Woah! Funky error. Thanks for reporting. It certainly looks like your Mercurial install is somewhat busted.

Are you using MozillaBuild 2.0? If not, please upgrade. If so, does `hg --version` work from your MozillaBuild shell? What about `c:\mozilla-build\python\Scripts\hg.exe --version` from a Windows command shell?

Comment 2

[Alpha Abdoulaye]

I installed the latest version of Mozilla build a few days ago, because it was recommended when I ran `mach mercurial-setup`

So here is the output of `hg --version`:

Mercurial Distributed SCM (version 3.4.1)

And here is the output for `c:\mozilla-build\python\Scripts\hg.exe --version` :

>c:\mozilla-build\python\Scripts\hg.exe --version

Comment 3

[Gregory Szorc [:gps]]

This sounds like a bug in MozillaBuild. RyanVM?

You may get a more useful stack trace by running:

  HGDEMANDIMPORT=disable c:\mozilla-build\python\Scripts\hg.exe --version

I can't remember if that is valid Windows command shell syntax. You may have to run SET to export the environment variable:

  $ SET HGDEMANDIMPORT=disable
  $ c:\mozilla-build\python\Scripts\hg.exe --version

I'd be interested in seeing that stack trace as well.

Comment 4

[Ryan VanderMeulen [:RyanVM]]

I could have sworn this was working while we were testing MB 2.0.

Comment 5

[Giulio Portioli [:gportioli]]

I get a similar failure, only after about fifteen of the wizard's [Y/n] questions. It then fails thus (see notes at the bottom):

    Would you like qnew to set patch author by default? [Y/n]

    Configured qnew to set patch author by default.

    Error running mach:

        ['mercurial-setup']

    The error occurred in code that was called by the mach command. This is either
    a bug in the called code itself or in the way that mach is calling it.

    You should consider filing a bug for this issue.

    If filing a bug, please include the full output of mach, including this error
    message.

    The details of the failure are as follows:

    ValueError: need more than 2 values to unpack

      File "c:\Users\Giulio\Projects\Mozilla\comm-central\mozilla\tools/mercurial/mach_commands.py", line 68, in mercurial_setup
        result = wizard.run(map(os.path.expanduser, config_paths))
      File "c:\Users\Giulio\Projects\Mozilla\comm-central\mozilla\tools/mercurial\hgsetup\wizard.py", line 385, in run
        bzuser, bzpass, bzuserid, bzcookie = c.get_bugzilla_credentials()



NOTES:
======
- MozillaBulid 2.0 installed
- Building comm-central, not mozilla-central
- 'hg --version' works in the MozillaBuild shell
- 'mozilla-build\python\Scripts\hg.exe --version' from a Windows shell FAILS with message "abort: failed to load Python DLL"

Has anyone got any suggestion? Thanks!

Comment 6

[Gregory Szorc [:gps]]

That last error is fixed in mozilla-central (87c4b1fb525534d447a8cd97ed9597b5112a060a / bug 1188931).

Comment 7

[Gregory Szorc [:gps]]

And, it sounds like the bug here is hg.exe is broken in a Windows command prompt (as opposed to MozillaBuild/msys/bash shell).

Comment 8

[Giulio Portioli [:gportioli]]

gps: thanks, that worked. As a side note, I notice that the mercurial.ini file created by mercurial-setup (on Win 8.1) has every line ending with CR CR LF (or '\r\r\n'), i.e. it seems to adopt the Mac and Windows file formats combined.
Not sure if it's worth tidying that up, anyway.

Comment 9

[Marco Castelluccio [:marco]]

I can reproduce this too (Windows 10).

Comment 10

[Marco Castelluccio [:marco]]

(I've just installed MozillaBuild 2.2.0)
