Problem:
19/06/10 Update: More evidence problem is server-side. Receiving this error on Windows 7 command line (see below for full traceback):
URLError: <urlopen error [Errno 10054] An existing connection was forcibly closed by the remote host>
abort: error: An existing connection was forcibly closed by the remote host
When attempting to push a changeset that contains 6 large files (.exe, .dmg, etc) to my remote server my client (MacHG) is reporting the error:
"Error During Push. Mercurial reported error number 255: abort: HTTP Error 404: Not Found"
What does the error even mean?! The only thing unique (that I can tell) about this commit is the size, type, and filenames of the files. How can I determine which exact file within the changeset is failing? How can I delete the corrupt changeset from the repository? In a different post, someone reported using "mq" extensions to effectively delete an erroneous changeset from the history within a repository, but mq looks overly complicated for what I'm trying to solve.
Background:
I can push and pull the following: source files, directories, .class files and a .jar file to and from the server, using both MacHG and toirtoise HG.
I successfully committed to my local repository the addition for the first time the 6 large .exe, .dmg etc installer files (about 130Mb total).
In the following commit to my local repository, I removed ("untracked" / forget) the 6 files causing the problem, however the previous (failing) changeset is still queued to be pushed to the server (i.e. my local host is trying to push the "add" and then the "remove" to the remote server - and keep aligned with the "keep everything in history" philosophy of the source control system).
I can commit .txt .java files etc using TortoiseHG from Windows PCs. I haven't actually testing committing or pushing the same large files using TortoiseHG.
Please help!
Setup:
Client applications = MacHG v0.9.7 (SCM 1.5.4), and TortoiseHG v1.0.4 (SCM 1.5.4)
Server = HTTPS, IIS7.5, Mercurial 1.5.4, Python 2.6.5, setup using these instructions:
http://www.jeremyskinner.co.uk/mercurial-on-iis7/
In IIS7.5 the CGI handler is configured to handle ALL verbs (not just GET, POST and HEAD).
My hgweb.cgi file on the server is as follows:
#!/usr/bin/env python
#
# An example hgweb CGI script, edit as necessary
# Path to repo or hgweb config to serve (see 'hg help hgweb')
#config = "/path/to/repo/or/config"
# Uncomment and adjust if Mercurial is not installed system-wide:
#import sys; sys.path.insert(0, "/path/to/python/lib")
# Uncomment to send python tracebacks to the browser if an error occurs:
#import cgitb; cgitb.enable()
from mercurial import demandimport; demandimport.enable()
from mercurial.hgweb import hgweb, wsgicgi
application = hgweb('C:\inetpub\wwwroot\hg\hgweb.config')
wsgicgi.launch(application)
My hgweb.config file on the server is as follows:
[collections]
C:\Mercurial Repositories = C:\Mercurial Repositories
[web]
baseurl = /hg
allow_push = usernamea
allow_push = usernameb
Output from the command line from my macbook (both Mercurial and MacHG installed) using -v and --trackback flags:

It is a keep-alive issue? Is IIS7.5 at fault? Python 2.6.5 at fault?
