尝试将大文件推送到服务器时 Mercurial 客户端错误 255 和 HTTP 错误 404
问题:
2010 年 6 月 19 日更新:更多证据表明问题出在服务器端。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
当尝试将包含 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”
该错误到底是什么意思?!关于此提交的唯一唯一(我可以告诉的)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,但对于我想要解决的问题来说,mq 看起来过于复杂背景
:
我可以使用 MacHG 和 toirtoise HG 将以下内容推送到服务器或从服务器拉取:源文件、目录、.class 文件和 .jar 文件,
我第一次成功地将添加内容提交到我的本地存储库 。 6 个大的 .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,我删除了(“未跟踪”/忘记)导致问题的 6 个文件,但是之前的(失败的)更改集是仍在排队等待推送到服务器(即我的本地主机正在尝试将“添加”然后“删除”推送到远程服务器 - 并与源代码控制系统的“将所有内容保留在历史中”理念保持一致) 。
我可以使用 Windows PC 上的 TortoiseHG 提交 .txt .java 文件等。我实际上还没有测试使用 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:

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)。
服务器上我的 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"

这是一个保持活动的问题吗?难道是IIS7.5出问题了? Python 2.6.5 有问题吗?
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!

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

经历了同样的痛点...
使用 IIS 服务器上的默认设置,您将无法将大型存储库推送到服务器,因为 IIS 的默认最大请求长度仅为 4 MB,并且 CGI 脚本有超时15分钟,无法上传大文件。
要启用大文件的上传(这在网络上不容易找到......),请执行以下操作:
1. 在 IIS 管理器中,单击网站节点,然后单击“限制...”链接。
2.然后指定足够大的连接超时(我这里选择1小时,即3600秒)
3. 接下来,单击包含 hg 的节点(按照安装过程),然后双击 CGI
4. 为 CGI 脚本指定足够长的超时(例如 10 小时)
现在,编辑 C:\inetpub\wwwroot\hg\web.config,使其具有新的
下的部分,以及
下的
规范:这指定了一个 http超时时间略多于 6 天,最大上传限制约为 2 GB。
Went through the same pain points...
With the default settings on the IIS server, you will not be able to push large repositories to the server, as IIS has a default maximum request length of only 4 MB, and a timeout for CGI scripts of 15 min, making it impossible to upload large files.
To enable the uploading of large files (and this is not easy to find on the web…), do the following:
1. In IIS Manager, click on the web site node, and click the Limits… link.
2. Then specify a connection time-out sufficiently large (I chose 1 hour here, or 3600 seconds)
3. Next, click the node containing hg (as per the installation procedure), then double-click CGI
4. Specify a sufficiently-long time out for CGI scripts (e.g., 10 hours)
Now, edit C:\inetpub\wwwroot\hg\web.config, so that it has a new
<security>
section under<system.webserver>
, and a<httpRuntime>
specification under<system.web>
:This specifies an http timeout of a bit more than 6 days, and a maximum upload limit of about 2 GB.
使用 IIS 7 作为服务器时遇到同样的问题。尝试了上面的解决方案,该解决方案解决了错误 255 问题,但对于较大的文件仍然出现 Errorno 10054。然后我增加了 IIS 中的连接超时,效果很好。
更改:网站->管理网站->高级设置->连接限制 ->连接超时。默认值为 2 分钟。把我的时间改为20分钟,成功了。
不知道为什么会这样,但似乎 Mercurial 与服务器建立了连接,需要一段时间来处理较大的文件,然后只发送一个请求。此时 IIS 已断开客户端连接。
Had the same issue using IIS 7 as server. Tried the solution above which resolved the error 255 issue, but still got Errorno 10054 with larger files. I then increased the Connection Time-out in IIS which worked.
To change: Web Site -> Manage Web Site -> Advanced Settings -> Connection Limits -> Connection Time-out. The default is 2 minutes. Changed mine to 20 minutes and it worked.
Not sure why this works but seems that Mercurial makes a connection to the server, takes a while to process larger files, then only sends a request. By that time IIS has disconnected the client.
好的,您的解决方案成功了!
我已经有一个像这样的 requestLimits 标签:
所以我像这样添加了 maxAllowedContentLength ="524288000":
就这样完成了!
Ok, your solution did it!
I already had a requestLimits tag like this:
<requestLimits maxUrl="16384" maxQueryString="65536" />
so I added maxAllowedContentLength ="524288000" to it like this:
<requestLimits maxUrl="16384" maxQueryString="65536" maxAllowedContentLength ="524288000" />
And that did it!
我只是将这个帖子发布给通过搜索进入该主题的其他人。
目前,通过 IIS 托管时,在 Mercurial python 模块中使用大型文件扩展存在问题。请参阅这篇文章如果您在通过 TortoiseHg 将大型变更集(或大型文件)推送到 IIS 时遇到问题。
该问题最终被证明是 Python 2.7.3 引入的 SSL 处理中的一个错误(可能解释了为什么有这么多未解决的帖子寻找 Mercurial 的问题)。回滚到 Python 2.7.2 让我可以更进一步(在 30Mb 推送而不是 15Mb 时被阻止),但为了正确解决问题,我必须安装 IISCrypto 实用程序可完全禁用通过 SSLv2 的传输。
I'm just posting this for anyone else coming into this thread from a search.
There's currently an issue using the largefiles extension in the mercurial python module when hosted via IIS. See this post if you're encountering issues pushing large changesets (or large files) to IIS via TortoiseHg.
The problem ultimlately turns out to be a bug in SSL processing introduced Python 2.7.3 (probably explaining why there are so many unresolved posts of people looking for problems with Mercurial). Rolling back to Python 2.7.2 let me get a little further ahead (blocked at 30Mb pushes instead of 15Mb), but to properly solve the problem I had to install the IISCrypto utility to completely disable transfers over SSLv2.
