Remember an old post i have done about the way i manage eclipse third part plugins dependencies, i have discover a web site where you can select the plugins you want and it build a bundle for you ready to be downloaded:
I have tried it and it rocks ! For 131 MO to download i got:
And you don’t have all Java’s stuff in your eclipse so it’s stay clean and start quickly.
I have work hard on testing/debugging an already developed specific app that handle local roles in a Plone site. I was sure that local roles was just manageable throw a permission but i have finally read the code that handle local roles and understand things:
* you can only add a role to somebody if you have the permission “Change local roles”
* you can only add a role to somebody if you this role in that context
* role are quiet on error (if you don’t have the role you are trying to add, you will not have any log)
* if you have manager role you can do what ever you want (don’t do your tests in manager !!! )
* else candidate local roles are only yours without ‘Anonymous’, ‘Authenticated’ and ‘Shared’
* local roles are stored in a dict called __ac_local_roles__ on the context
After one day of work with local roles, i think the most painful part is to don’t have log, even in debug mode. When a process is called to do a job and it do half of it, i think it has to said something.
But local roles are an essential part of Plone that i really like.
PS: i have discover to late a good module to display local roles in Plone: zopyx.plone.cassandra.
yet an other post to say svn sucks. yes it is. But many people who use svn are happy with it and i was happy to.
It’s hard to maintain a trunk when 5 people are commiting on it during the project life. So i have started to look at DVCS (git hg, bzr). I have tryied GIT because of it’s popularity.
At work, someone is using mercurial (hg) and we are two people intersting in GIT. So i have decided to test it but over SVN. it means the central repository is still an svn one.
Here is the way i m using it:
1. clone the repo (git svn clone blabla)
2. branche
3. work on your code (commit, …)
4. merge on master
5. git svn dcommit
And you get it, only one commit on the trunk (master) and the power of git to merge, commit, …
Some cool features and properties of git:
But there are some point i have not found handy:
I hope all that things will be improved in the futur of git, but now i m using git at work. Next step will be code review TTW.
I just want to try to make a simple application with the best of current opensource technologies. Got a try with those one:
I have take an hour to install this on my laptop, with the excellent virtualenv to build a copy of an already installed python in a directory.
/path/2/python/bin/virtualenv --no-site-packages /path/2/project
Next i have use zopeproject to install the last zope3 technologies. Now zopeproject use the KGS to set the version of eggs to use.
cd /path/2/project source bin/activate easy_install zopeproject zopeproject myproject
You get it, you have the last release of zope3.4 release. Now add the eggs you want to use
eggs = ...
psycopg2
RelStorage
ore.alchemist
hurry.zopeyui
z3c.form
# chameleon.zpt require zope.i18n > 3.4
modify your zope.conf to configure RelStorage:
%import relstorage
<zodb>
<relstorage>
<postgresql>
# The dsn is optional, as are each of the parameters in the dsn.
dsn dbname='zope' user='zope' host='localhost'
</postgresql>
</relstorage>
</zodb>
Now, you get your zope3.4 running on python2.5 and store the zodb data in postgresql. I have lost most of the time on RelStorage and postgresql configuration. I’m to work with all those technologies.
I will work on making a simple blog in pure zope3, and next i will try to make the same application with SqlAlchemy.
