sslErrors attribute in Ghost.py

[aflaxman]

I'm trying to use Ghost.py with the anaconda python distribution, and running into an issue with the self.manager.sslErrors.connect call. Do you have any ideas for a fix or work-around?

Here is the full error:

This is using pyside 1.2.1:

C:\Users\abie\AppData\Local\Continuum\Anaconda>conda update pyside
Fetching package metadata: ..
# All requested packages already installed.
# packages in environment at C:\Users\abie\AppData\Local\Continuum\Anaconda:
#
pyside                    1.2.1                    py27_0

I posted a similar issue in the Ghost.py issue tracker here

check this thread. your pyside may compiled with no open ssl support.
to fix the problem.

pip uninstall PySide
pip install -U PySide

will do for you.

[brandon-rhodes]

I am in a more Anaconda-specific position. Rather than getting this error because of a third-party PySide installation, I am getting it directly from the PyQt library that was installed directly by conda.

$ conda list pyqt
# packages in environment at /home/brandon/.v/fopnp-py3:
#
pyqt                      4.10.4                   py34_0  

In the next version of PyQt, could Continuum.io set the compile options on PyQt so that it can discover the version of OpenSSL that you ship and thus make libraries like ghost.py able to operate under the Anaconda-installed Python? Thanks!

[asmeurer]

We can try. Is it pyqt or qt itself? QT doesn't really have compile options. It just finds whatever it can when it runs its configuration script and compiles in support for and links against whatever it finds.

[brandon-rhodes]

The problem is with Qt itself, if I am interpreting the lack of “ssl” symbols in Anaconda’s version of the library correctly:

$ nm -CD /usr/lib/i386-linux-gnu/libQtNetwork.so.4.8.6 | grep ssl
000db5f0 T QSslSocket::sslErrors(QList<QSslError> const&)
000f2520 T QNetworkReply::sslErrors(QList<QSslError> const&)
00053b10 T QNetworkAccessManager::sslErrors(QNetworkReply*, QList<QSslError> const&)
00032930 T QHttp::sslErrors(QList<QSslError> const&)
000dd5b0 T QSslSocket::sslConfiguration() const
000df230 T QSslSocket::sslErrors() const
00070f80 T QNetworkReply::sslConfiguration() const
0006d120 T QNetworkRequest::sslConfiguration() const
$ nm -CD .anaconda/lib/libQtNetwork.so.4.8.5 | grep ssl
$

[asmeurer]

In theory, it should be enough to add openssl to the build requirements of qt (and double check that it is enabled in the configure step).

[asmeurer]

@brandon-rhodes can you try the qt package I just built and put on my binstar. conda install -c asmeurer qt. It is for 64-bit Linux only.

[asmeurer]

Ah just noticed that the configuration script still lists no openssl support. So maybe it does have to be enabled with a flag somehow.

[asmeurer]

I'm not sure. If I set the -openssl or -openssl-linked flags (and also include openssl in the build requirements) it doesn't want to build with OpenSSL support.

[brandon-rhodes]

I wonder what it does not like your OpenSSL, when you have it included in all of the build and LD_LIBRARY_PATH settings? (I have not been able to try your 64-bit build yet because my machine is 32-bit.)

[asmeurer]

I deleted my build from binstar once I realized it wasn't any good. If I play with this more I will build on a 32-bit machine.

[goanpeca]

I am running in the same issue on:
'QNetworkReply' object has no attribute 'sslErrors'

I am running on Ubuntu with
Python 2.7.9 64bits, Qt 4.8.5, PyQt4 (API v2) 4.10.4 on Linux

[ccordoba12]

Since Anaconda 2.2, Qt is complied against our openssl package. This means that the Ssl symbols are now part of Qt and PyQt.

[brandon-rhodes]

Thank you!
