PyQt4 bug preventing it from working properly in Pydev (and workaround)

Hi All,

There have been some reports on people with problems to get PyQt4 working properly in Pydev... This is because depending on the version of PyQt4 it has a major bug that will crash a Python interpreter (this was confirmed in version 4.5.4 -- haven't checked on other versions).

To know if you have a version with this problem you can check it by running the code below in an interactive session:

>>> from PyQt4.QtCore import *
>>> QSignalMapper

>>> import inspect
>>> inspect.ismodule(QSignalMapper) <-- this will make the interpreter
crash!

If that's your problem, right now you have to fix Pydev by editing

eclipse/plugins/org.python.pydev/PySrc/importsTipper.py at line 154,
changing:
"for d in dirComps:"

to:

for d in dirComps:
    if d == 'QSignalMapper':
        continue

Or get another PyQt4 version.

Pydev 1.5.1 released

Yeap, this release took more time than usually, but I hope it was worth it. The major things as I posted previously were related to the refactoring engine.

There were also a number of other minor problems and features done along the way.

The complete info may be found at: http://pydev.org/

So, now that it's out, what's next?

Well, the last releases were all about giving more power to the user (refactoring, jump in the debugger, app engine, merging pydev extensions to pydev, IronPython support -- did I mention that the pydev debugger is now working with the latest IronPython?), so, I think that now would be a good time to step back a little and work on ironing out the bugs and making some profiling sessions (for both speed and memory).

Pydev 1.5.1 almost there

Ok, all the planned changes for 1.5.1 are now in place and the current version already seems pretty stable, so, the current nightly build (available as an update site at http://pydev.org/nightly) will be the final version unless there's some critical bug found (so, if there's anyone interested, it'd be nice testing that version).

The major changes were:

- Improvements in the AST rewriter
- Improvements on the refactoring engine (no longer using BRM, merged with the latest PEPTIC and added/fixed lots of cases for corner-case situations)
- Improvement in the type inference engine for lists

And along that there were a good number of minor editor improvements and bug-fixes.
