I’m trying to get the largefiles extension working on a mercurial server under Windows Server 2008 / IIS 7.5 with the hgweb.wsgi script.
When I clone a repo with largefiles locally (but using https://domain/, not a file system path) everything gets cloned fine, but when I try it on a different machine I get abort: remotestore: largefile XXXXX is missing
Here’s the verbose output:
requesting all changes

added 1 changesets with 177 changes to 177 files

abort: remotestore: largefile c0c81df934cd72ca980dd156984fa15987e3881dis missing
Both machines have the extension working. I’ve tried disabling the firewall but that didn’t help. Do I have to do anything to set up the extension besides adding it to mercurial.ini?
Edit: If I delete the files from the server’s AppData\Local\largefiles\ directory, I get the same error when cloning on the server, unless I use a filesystem path to clone, in which case the files are added back to `AppData\Local\largefiles\’
Edit 2: Here’s the debug output and traceback:

The _getfile function throws an exception because the statlfile command returns that the file wasn’t found.
I’ve never used python myself, so I don’t know what I’m doing while trying to debug this 😀
AFAIK the statlfile command gets executed on the server so I can’t debug it from my local machine. I’ve tried running python -m win32traceutil on the server, but it doesn’t show anything. I also tried setting accesslog and errorlog in the server’s mercurial config file, but it doesn’t generate them.
I run hg through the hgweb.wsgi script, and I have no idea if/how I can get into the python debugger using that, but if I could get the debugger running on the server I could narrow down the problem…
Finally figured it out, the extension tries to write temporary files to
%windir%\System32\config\systemprofile\AppData\Local, which was causing permission errors. The call was wrapped in a try-catch block that ended up returning the “file not found” error.
