Android on-device debugging launch fails: Can’t bind to local 8600 for debugger

Mikko Ohtamaa — Wed, 01 Dec 2010 20:08:44 +0000

You try to launch Android app on the device from Eclipse. The debugger fails to connect and times out. Instead, you see this in the Console log:

Can't bind to local 8600 for debugger

To fix this do the following steps exactly in this order

Close Eclipse
Disconnect USB cable
Kill all adb instances on the task manager of your computer
Start Eclipse
Connect USB cable
Launch the application

If this does not help then make sure that you are using IPv4 address for localhost DNS loopback name. Edit /etc/hosts and comment out all IPv6 entries.

Eclipse plug-in for Plone/Zope/buildout based development

Mikko Ohtamaa — Mon, 29 Mar 2010 10:01:47 +0000

Few days ago Fabio announced Django plug-in for Eclipse. There also exists an effort to make Eclipse integrate smoother with Plone / Zope / Buildout world.

Please see PyPi page here.

It is not nearly as polished as Fabio’s work, as Fabio being main author of PyDev and started as a collection of company internal tools. However if you mare making many buildouts, write code > 5 Python modules at once and don’t want to start terminal everytime you need to run buildout, this plug-in is for you.

Also, it is not yet a real plug-in. It is a collection of PythonMonkey scripts. This means that to deploy the scripts you simply copy .py files them to scripts folder of any of your Eclipse projects. If you need to work on the codebase, you don’t need to start a separate Eclipse instance, but you can do it interactively through Eclipse console while you do other development. The script source code is well commented, so if you want to tune them for your own habits it should be easy.

PyDev, Python and system default Unicode encoding problem

Mikko Ohtamaa — Sun, 24 Jan 2010 17:02:33 +0000

Python 2 has a thing called “default encoding” to automagically encode Unicode strings when they are presented as byte strings. This is evil and has been discussed various times before.

What could be even more evil? Something in your development environment messes this setting set for you, without telling you that. This way you never encounter Unicode problems on your development computer and when you roll out your seemingly working code to production, the world goes haywire.

Evil. Evil. Evil. Thousands of curses and overworking hours to fix the problems.

I encountered this problem. And this is the code I used to track the problem down in site.py:

# Trap the bastard messing with the default encoding
# using a monkey patch
old_set_default_encoding = sys.setdefaultencoding

def aargh(x):
    import pdb ; pdb.set_trace()

sys.setdefaultencoding = aargh

And the result was surprising:

--Return--
> /home/moo/py24/lib/python2.4/site.py(485)aargh()->None
-> import pdb ; pdb.set_trace()
(Pdb) bt
/home/moo/py24/lib/python2.4/site.py(613)?()
-> main()
/home/moo/py24/lib/python2.4/site.py(604)main()
-> execsitecustomize()
/home/moo/py24/lib/python2.4/site.py(514)execsitecustomize()
-> import sitecustomize
/home/moo/Desktop/Aptana Studio 2.0/plugins/org.python.pydev_1.5.3.1260479439/PySrc/pydev_sitecustomize/sitecustomize.py(99)?()
-> sys.setdefaultencoding(encoding) #@UndefinedVariable (it's deleted after the site.py is executed -- so, it's undefined for code-analysis)
> /home/moo/py24/lib/python2.4/site.py(485)aargh()->None
-> import pdb ; pdb.set_trace()

--Return--> /home/moo/py24/lib/python2.4/site.py(485)aargh()->None-> import pdb ; pdb.set_trace()(Pdb) bt  /home/moo/py24/lib/python2.4/site.py(613)?()-> main()  /home/moo/py24/lib/python2.4/site.py(604)main()-> execsitecustomize()  /home/moo/py24/lib/python2.4/site.py(514)execsitecustomize()-> import sitecustomize  /home/moo/Desktop/Aptana Studio 2.0/plugins/org.python.pydev_1.5.3.1260479439/PySrc/pydev_sitecustomize/sitecustomize.py(99)?()-> sys.setdefaultencoding(encoding) #@UndefinedVariable (it's deleted after the site.py is executed -- so, it's undefined for code-analysis)> /home/moo/py24/lib/python2.4/site.py(485)aargh()->None-> import pdb ; pdb.set_trace()

Looks like the culprint was PyDev (Eclipse Python plug-in). The interfering source code is here. Looks like the reason was to co-operate with Eclipse console. However it has been done incorrectly. Instead of setting the console encoding, the encoding is set to whole Python run-time environment, messing up the target run-time where the development is being done.

There is a possible fix for this problem. In Eclipse Run… dialog settings you can choose Console Encoding on Common tab. There is a possible value US-ASCII. I am not sure what Python 2 thinks “US-ASCII” encoding name, since the default is “ascii”.

Updated: Eclipse web developer plug-in memo

Mikko Ohtamaa — Sun, 13 Jul 2008 23:13:04 +0000

Below are my personal notes what plug-ins are needed to get “perfect” Eclipse web development set-up. Basically they are just my own notes so that I don’t need to Google everything all over again every time I reinstall. I hope the readers can find new pearls here or suggest improvements.

This post is update to previous Eclipse web developer plug-in memo post. New versions are available and some plug-ins have become deprecated. This blog post reflects those changes.

These instructions are good for:

Python developer
PHP developer
Java developer

Choosing Eclipse distribution

On Window, use EasyEclipse
On Linux, use Eclipse provided by the distribution – Eclipse links against the embedded Mozilla browser and this is distribution specific – EasyEclipse has some issues here. For Ubuntu users:

sudo apt-get install sun-java6 eclipse

On OSX, use EasyEclipse

EasyEclipse bundles some of the stuff listed here with it – when using EasyEclipse you don’t need to have separate PyDev and Subclipse downloads.

Eclipse for 64-bit Linux has various problems. You might want to run 32-bit Eclipse (another relevant blog post). When you use Linux distribution specific Eclipse install, all your personal Eclipse files go to .eclipse folder under your home folder.

Installing plug-ins

Eclipse has internal updater/web installer. All plug-ins are downloaded as ZIP files and extracted to Eclipse folder or installed through the internal updater. Paste Eclipse update site URLs to menu Help -> Software updates -> Find and Install, New Remote Location.

Python

PyDev is a plug-in for Python and Jython development. It has enhanced commercial extensions for professional developers with more intelligent autocomplete and debugger.

Site URL: http://pydev.sourceforge.net

PyDev Eclipse update URL: http://pydev.sourceforge.net/updates/

PyDev extensions Eclipse update URL (this commercial, but worth of every penny): http://www.fabioz.com/pydev/updates

PDT

PDT download provides Eclipse, HTML editor, PHP editor and CSS editor.

Site URL: http://www.eclipse.org

Eclipse update site URL: http://download.eclipse.org/tools/pdt/updates/

Java

If you need to do J2EE development use IBM’s Web Tools Platform. If you don’t need Java capabilities don’t install these, since they just bloat Eclipse and make the start up time worse.

Subclipse

Subclipse provides Subversion version control integration to Eclipse.

Eclipse update site URL: http://subclipse.tigris.org/update_1.4.x/

In the installer, uncheck the integration modules checkbox or the installer will complain about missing modules.

Aptana Studio

Aptana Studio is state-of-the-art Web 2.0 development suite for Eclipse. It has Javascript, CSS and HTML editors. It supports various Javascript libraries out of the box and has support for Firefox and IE in-browser Javascript debugging.

Eclipse update site URL: http://update.aptana.com/update/studio/3.2/site.xml

ShellEd

Syntax coloring for Unix shell scripts

Project site: http://sourceforge.net/projects/shelled

SQL Explorer

SQL terminal and SQL editor with some GUI capabilities.

Eclipse update site URL http://eclipsesql.sourceforge.net/

SQL Explorer needs MySQL JDBC driver. Download from here. Install MySQL connector by extracting the file and adding it from SQL Explorer preferences.

Eclipse web developer plug-in memo

Mikko Ohtamaa — Tue, 27 Nov 2007 11:46:19 +0000

Currently I work in quite wide field of software development: Python (standalone, Plone, Zope, Django), PHP, Java, Symbian and embedded Linux. I am using Eclipse for development, since it’s pretty much the only consistent platform filling my needs. The nature of work also forces me to use different computers (Mac/Windows/Linux) with different clients. This drives me to reinstall Eclipse now and then.

Below are my personal notes what plug-ins are needed to get “perfect” Eclipse set-up. Basically they are just my own notes so that I don’t need to Google everything all over again every time I reinstall. I hope the readers can find new pearls here or suggest improvements.

Eclipse setup

Eclipse has internal updater/web installer. All plug-ins are downloaded as ZIP files and extracted to Eclipse folder or installed through the internal updater. Paste Eclipse update site URLs to menu Help -> Software updates -> Find and Install, New Remote Location. You can use dummy text as the name of update site.
