Mercurial extensions not working in Windows 7 x64?
We are test driving Mercurial at work. We don't want to have to enter our user/pass each time we interact with a repository, so we set up the mercurial_keyring extension. We:
- Installed Python 2.6.5 (32 or 64 bit, depending on the system)
- Installed setuptools (for easy_install.exe)
- easy_install keyring
- easy_install mercurial_keyring
And then made the appropriate changes to %userprofile%/mercurial.ini in the [auth] section. It works fine on my colleague's computer (32bit xp sp3), but it does not work on my machine (Windows 7 Ultimate x64). Also noteworthy, the setuptools had to be built from source on Win 7 x64 (python setup.py bdist_wininst, then run the resulting setuptools-0.6c11.win-amd64.exe).
Using just hg.exe from the Mercurial 1.5 binary installation (the .msi), I get this error when I run hg.exe:
*** failed to import extension mercurial_keyring: No module named mercurial_keyring
I tried to change my mercurial.ini, to specify the path to the mercurial_keyring.py file, instead of having mercurial find it (since it's in the PYTHONPATH).
Old:
[extensions]
mercurial_keyring =
New:
[extensions] mercurial_keyring =
c:/mercurial/extensions/mercurial_keyring.py
The error changes to:
abort: could not import module keyring!
So while providing the path to the mercurial_keyring extension works, the dependent keyring module still cannot be found.
After further investigation, it appears that NO extensions work. They all produce the error:
*** failed to import extension [extension name]: No module named [module name]
It appears that when running hg.exe, it is not aware of PYTHONPATH. I have tried:
- Python 2.6.5 32 bit
- Python 2.6.5 64 bit
- Building Mercurial 1.5 from source with MinGW
- Building Mercurial 1.5 from source with MSVC9
- Using hg.exe from the 1.5 binary dist (.msi)
- Using the hg.py in c:\python26\scripts when building from source
- Various configurations in %userprofile%/mercurial.ini
- Using setuptools (easy_install.exe) to install keyring and mercurial_keyring
- Building keyring and mercurial_keyring from source (python setup.py bdist_wininst)
Nothing works. The closest I've got is using hg.py when building from source. It at least doesn't give me errors, and actually creates %userprofile%/wincrypto_pass.cfg when I enter my credentials. But on subsequent requests, it doesn't enter the credentials automatically. It prompts me for them again.
Interestingly, TortoiseHG is using the keyring. I just can't get it to work on the command line. I think something is going on with Win 7 x64 that is preventing mercurial (hg.exe) from seeing the PYTHONPATH, so it can't find any of the installed modules.
Does anyone have extensions working in Win 7 x64? Specifically with the binary installation of mercurial (not hg.py)?
UPDATE I've found a suitable work around for now. Since TortoiseHG does work with mercurial_keyring, I've simply changed my PATH setup to include the tortoiseHG folder, but not c:\mercurial. Now when I type "hg" at the command line, it's using the hg.exe in the tortoiseHG folder, which works fine. Just the same, this is still a problem with mercurial extensions on Win 7 x64. Answers welcome.
Answer
Answering my own question with my previous update, since there are no other takers yet.
Suitable workaround: Since TortoiseHG does work with mercurial_keyring, I've simply changed my PATH to include the tortoiseHG folder, and exclude c:\mercurial. Now when I type "hg" at the command line, it's using the hg.exe in the tortoiseHG folder, which works fine with the keyring.
