I am attempting to run a local version of the schema.org app so I can write a proposal for an addition to the ontology. I followed the tutorial at http://dataliberate.com/2016/02/10/evolving-schema-org-in-practice-pt1-the-bits-and-pieces/, which had me set up Google App Engine and download a forked version of schema.org using Git.
Unfortunately, I cannot get the schema.org app to run on my machine. Sample GAE apps work fine, but whenever I start the schema.org app I get the following error:

INFO 2016-09-29 10:54:39,951 module.py:788] default: "GET /_ah/warmup HTTP/1.1" 500-
The problem is occurring when it tries to parse the RDF, but I suspect the lack of RDF output is being caused by the 500 error. I have done an extensive search and found plenty of examples of the 500 error with GAE, but none of the suggested fixes has worked (e.g., increasing the TIMEOUT setting, rolling back to SDK 1.36).
I am running the app on localhost:9080. I get a 500 error whenever I try to access it from the browser. I can, however, access the admin at localhost:8001. For some reason, it shows two instances running.
Any help would be greatly appreciated. Let me know if you need more information.
This problem has now been fixed with a Windows specific patch to the Schema.org code line as referenced in Git Issues (#1384) and (#1412)
A pull of the latest code from the repository should clear the problem.

I am trying to run a discord bot using discord.py and through a proxy. The discordpy doc on this is pretty scarce on the subject and not up to date with aiohttp implementation.
discordpy doc basically says to use a ProxyConnector and pass it as an argument when the client is created.
But in aiohttp, this way is deprecated and client.ClientSession().get is recommended instead. Problem is, client.ClientSession().get asks me to provide a URL.
I also tried with ProxyConnector anyway, but it doesn't work when I finally run the bot (can't connect to the discord API). I'm not sure what's wrong with it, as the proxy itself works fine with any other HTTPS services.
Code with recommended way
conn = client.ClientSession().get(proxy='<proxy_url>', proxy_auth=BasicAuth(<proxy_auth>))
self.client = discord.Client(connector=conn)
Code with deprecated way
conn = ProxyConnector(proxy='<proxy_url>', proxy_auth=BasicAuth(<proxy_auth>))
self.client = discord.Client(connector=conn)

From continuing research, I found this link with this answer:
It appears that WebSockets used by discord.py do not support HTTP
proxies. This would just magically work with HTTPS, but since the
proxy is HTTP it doesn't. That means that, short of rewriting
discord.py with HTTP proxy support (by using websocket-client, for
example, which supports HTTP proxies), we may be out of luck.
It looks like it might not be possible to do it altogether.
I am really new on gae, but I have a task that have to deploy on google.

please, any help would be good.
After a few days, it worked again. I think it is Google App Engine's thing and I don't know its reason so far. But if you just want to use the deploy-on-localhost function, please step to other tools, it will be easier. Suggestion: MAMP.

Try to use this command:"
python splitdata.py .../big.json to split file in more mini.json. In this case you will can ingest json's and find which file is broken.
for example :
after splitting will have:
big-1.json
big-2.json
big-3.json - broken
big-4.json
big-5.json
continue to insert 1,2,4,5 - and than try to split again big-3.json ... infinit than, you will find broken file, which you can repair manually.
I'm just getting started with Mercurial, downloaded and installed hg command-line for Windows, cloned a new BitBucket repository, added a file, but when I commit I get this error:

The added file is definitely in the repository folder. When I run hg status I get:

In googling the question, lots of references to TortoiseHG appeared. I did used to have that installed, but got rid of it and restarted, there doesn't seem to be anything left on the system. Any ideas as to what I could try, or any mistakes I might have made?
Use double quotes: hg commit -m "first commit"
Just to note you can get this error due to unwittingly having a space between the dash and the m i.e.
- m as opposed to -m.
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?
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>:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
[…]
<security>
<requestFiltering>
<requestLimits maxAllowedContentLength ="2147482624" />
</requestFiltering>
</security>
</system.webServer>
<system.web>
<httpRuntime
executionTimeout="540000" maxRequestLength="2097151"/>
</system.web>
</configuration>
This specifies an http timeout of a bit more than 6 days, and a maximum upload limit of about 2 GB.
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.
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!
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.
