I mean freezing, not deadlocking.

Session deadlocking

2008-10-02T22:40:14Z

If the CherryPy process does not have access to the file-based session
dir you're using, or for whatever reason it gets an OSError when
trying to write a lockfile, this code deadlocks:

In particular, the "except OSError: time.sleep()" thing. At a minimum,

Prevent open sockets from being inherited by child processes

2008-09-18T18:48:49Z

Hello everybody,

Have you seen the patch I submitted some days ago, attached to ticket

--> [link]

It's about preventing open sockets from being inherited by child
processes.

Do you think it can be useful and committed to the trunk?

Cheers,

Silvain is right. You need to make a Python binding for your C++ module.
I've had good experiences using py++ to do this.

Hi,
CherryPy doesn't actually care about it. Just create a Python binding to
your C++ code (using sip, SWIG, boost, etc.) and import that binding
inside CherryPy.
The only aspect you have to be careful of is thread safety. CherryPy
heavily uses threads so depending on what your library does it may be a

Linking C++ API with CherryPy

Dear All,
I have a requirement in my project, where I need to some home-grown C+
+ source code from CherryPy framework. I would like to know whether
the cherrypy framework does support for C++ code integration. If it
does supports for C++ code integration, I would like to know how it
could be done. Could anyone please throw somelight on this problem?

I tried adding this to send_headers():

always be greater than -1 in this case.

I think your analysis is right on the mark.
If the developer only wants one thread, there's not much we can do about
saturation at that point. The developer can set
environ["HTTP_CONNECTION"] = "close" for all responses, and wsgiserver
will dutifully close the conn. The environ is inherited from
HTTPConnection, which is inherited from CherryPyWSGIServer, and

HTTP Thread Usage Saturation with Persistent Connections

2008-08-30T18:04:12Z

I am seeing instances of poor performance (hangs up to the default 10
second socket timeout) when the HTTP server threads all have active
persistent connections open. I believe this case can happen more
frequently than anticipated. I added debug logging to wsgiserver to
see what was occurring in these situations. Below is my analysis and

[patch] Directory listings for static directories

2008-05-31T03:54:15Z

I came up with a small patch for 3.1.0rc1 to implement optional
directory browsing for static directories.

Setting tools.staticdir.generate_index es=True turns it on.. Setting
the config to a callable lets you generate generate indexes yourself.

No doubt this is imperfect in many ways, but I figured it might be a
