How do I get Mercurial's hgwebdir working on Windows?

Question

These are the steps I took:

• install apache 2.2.x
• install TortoiseHg 0.7
• copy hgwebdir.cgi, hgweb.config to cgi-bin
• edit hgweb.config

Answer 1

you missed the c libs of mercurial

there are 3 ways to get out of this

1. recent mercurial versions ship with pure python implementations you can find in mercurial/pure
2. compile it yourself (im not exactly sure on the steps, on any unix this just works)
3. grab win32 installer from the website
   note that i didn't yet take a look at how those are build
   (you need a distutils based install, not a py2exe based one)

Answer 3

I know this question is already answered, but I experienced a slightly different issue and found a work around --

I'm sure I'm missing something obvious in the Python configuration (2.5.4), but I'm having issues with .pyd versus .dll. (I had the same issues with the Python subversion libraries.) I see osutil.pyd in Mercurial\library.zip, but it fails to load it. Therefore, I unzipped library.zip and then copied *.pyd to *.dll, e.g:

REM Ugly DOS... Recursively renames all .pyd files to .dll
for /f "tokens=*" %%a in ('dir /s /b *.pyd') do copy "%%a" "%%~da%%~pa%%~na.dll"

Make sure the unzipped library directory is in the PYTHONPATH, but after this I successfully can execute: from mercurial import osutil. Also remember to copy or move the Templates directory to the newly unzipped library directory.

Follow the steps in Section 5 of the HgWebDirStepByStep for the rest. I did not experience the "Gotchas" in Section 5.3 though.

Answer 4

First thing: don't use TortoiseHg for this. Use the Mercurial installer instead.

(TortoiseHg tries to be as independent of your Python installation as possible, and for reasons unclear to this Python-newbie, things Don't Work. Something about py2exe.)

Otherwise, just follow the steps in the HgWebDirStepByStep. I did have to install pywintypes, but YMMV. Lastly, the unzip utility mentioned on that page may do strange things with file permissions: I had to add read permissions to Templates directory and its files/subdirectories.

As an aside, if you're wondering how to set the style, add this to hgweb.config:

[web]
style = foo

Answer 5

My setup involves an apache 2.2.17, mod_wsgi 3.3, python 2.7.2, trac 0.12.2, mercurial 1.8.4. Two issues surfaced:

1. mercurial demandimport initialization order
2. mercurial unable to load DLLs in site-packages.

I solved the problem as follows:

1. change hgwebdir.wsgi to disable demandimport:

from mercurial import demandimport; demandimport.disable()

2. create a pure (.py only, no compiled .pyd) mercurial package and install. See also https://www.mercurial-scm.org/wiki/WindowsInstall

E:\Dist\mercurial-1.8.4>setup.py --pure build
E:\Dist\mercurial-1.8.4>setup.py --pure install

The compiled versions (with Microsoft Visual Studio 2008) fail to load the DLL:
