问题：
19/06/10 更新：更多的证据问题是服务器端的。在 Windows 7 命令行上收到此错误（完整回溯见下文）：
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
尝试将包含 6 个大文件（.exe、.dmg 等）的变更集推送到我的远程服务器时，我的客户端 (MacHG) 报告错误：
“推送期间出错。Mercurial 报告错误号 255：中止：HTTP 错误 404：未找到”
错误甚至是什么意思？！关于此提交的唯一独特之处（我可以说）是文件的大小、类型和文件名。如何确定变更集中的哪个确切文件失败？如何从存储库中删除损坏的变更集？在另一篇文章中，有人报告说使用“mq”扩展来有效地从存储库中的历史记录中删除错误的变更集，但 mq 对于我要解决的问题来说看起来过于复杂。
背景：
我可以使用 MacHG 和 toirtoise HG 在服务器之间推送和拉取以下内容：源文件、目录、.class 文件和 .jar 文件。
我第一次成功地向我的本地存储库提交了 6 个大型 .exe、.dmg 等安装程序文件（总共约 130Mb）。
在对我的本地存储库的以下提交中，我删除（“未跟踪”/忘记）导致问题的 6 个文件，但是前一个（失败的）变更集仍然排队等待推送到服务器（即我的本地主机正在尝试推送“添加”然后“删除”到远程服务器 - 并与源代码控制系统的“保留历史记录”理念保持一致）。
我可以使用 Windows PC 上的 TortoiseHG 提交 .txt .java 文件等。我实际上并没有测试使用 TortoiseHG 提交或推送相同的大文件。
请帮忙！
设置：
客户端应用程序 = MacHG v0.9.7 (SCM 1.5.4) 和 TortoiseHG v1.0.4 (SCM 1.5.4)
服务器 = HTTPS、IIS7.5、Mercurial 1.5.4、Python 2.6.5，使用以下说明进行设置：
http://www.jeremyskinner.co.uk/mercurial-on-iis7/
在 IIS7.5 中，CGI 处理程序被配置为处理所有动词（不仅仅是 GET、POST 和 HEAD）。
我在服务器上的 hgweb.cgi 文件如下：
#!/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)
我在服务器上的 hgweb.config 文件如下：
[collections]
C:\Mercurial Repositories = C:\Mercurial Repositories
[web]
baseurl = /hg
allow_push = usernamea
allow_push = usernameb
使用 -v 和 --trackback 标志从我的 macbook（安装了 Mercurial 和 MacHG）的命令行输出：

这是一个保持活力的问题吗？IIS7.5 有问题吗？Python 2.6.5 出错了？
