Thanks for the response. After some snooping around tonight, I was
suspecting that'd be the option to use. But then I decided to try
using IGroupedPrincipal instead. So now when my site configurator sets
up this particular site/app, it:
- Denies permission 'zope.View' to role 'zope.Anybody'
- Grants permission 'zope.View' to principal 'presenter.group'
My authenticator recognizes that and returns an IGroup. All of the
presenters returned have a groups attribute with the value
['presenter.group']. Seems to work so far, and I'm breathing a sigh of
relief tonight. Sure beats hoping I don't mess up an IPrincipalRoleMap
when I've got so much other work to do and am so far behind as it is.
Wheee, life!

Nope. I've got a 1.33 G4, so I need about the same amount of time. Of course, you *can* speed up the start up a little bit by disabling all the stuff you don't need. ZCML execution isn't exactly fast, so any package you don't need and can live without, even if it's only for the moment, saves you startup time. > After some reading it sounds like the way to go with Zope is to just > write lots of those "tests", which run much much quicker.

This is definitely a good way of reducing the amount of restarts one has to make. Typically, I write at least the basic unit tests for components before I think about their ZCML registration or even starting up Zope. Often, I also write science fiction tests, meaning, I first write a test that illustrates how I'd like the component to behave, and then I implement the component until the tests pass. Either way, writing the basic unit tests definitely will catch "stupid" errors immediately, such as import errors, typos, etc. > Right now I'm concerned about what will happen when I start testing the > security and the design (skin). My guess is there are mechanisms to > write tests to try out the the security settings Of course there are. We call those functional tests and usually write them using a test browser (see zope.testbrowser). For more info on functional tests (though not on the test browser as it's more recent technology), I can refer you to my book, http://worldcookery.com. > but if I makes design > changes I obviously can't look at those via the command line.

RE: [Zope3-Users] development workflow
I'm somewhat of a novice myself and big PHP fan, and I've found the tests just as slow as restarting, and they don't always cover everything the way I expect (although I think this may be due to my ignorance). I spend a lot of time in ZCML and they don't do so well there. I think it is good practice to write tests, but I've not worked up enough expertise to use them effectively, and they therefore impede my development; I suspect my opinion will change in time as I get more proficient. I have found that you can edit page templates without restarting, which helps tremendously. The restart process for me is about 5 seconds, so it's not that bad.

I'm developing a multilingual site, too. It works like this:

* users can click on one of 3 small flags to override browser preferences
with a different language
* all data fields on content objects are stored as dictionaries like this:

hi there I'm new to Zope development from the PHP realm. When I worked in PHP I would, write a little code, save it, refresh the browser and see what happened.

After some reading it sounds like the way to go with Zope is to just write lots of those "tests", which run much much quicker. So my development processes looks something like this: 1. write code 2. write tests 3. run tests 4 debug 5. repeat steps 1-4 until there's a whole bunch of new features and I can't stand not trying them out. 6. restart zope and try things out. Is that how Zope 3 development is supposed to work? Right now I'm concerned about what will happen when I start testing the security and the design (skin).

Re: [Zope3-Users] KeyError: Surrogate
Hi Bernd. Personally, I think zope and twisted is a good combination.
Are you still running twisted in your installation or are you using
zserver for your instances? Had you posted on twisted list to see if
this triggered any discussion?
I am wondering what it means by surrogate? As in codec surrogate? If
this were the case, I wonder why it would not be a decoding error you
would receive instead. One kind of surrogate issue is when you have an
incomplete byte sequence for a character in a codec. I found this
explanation of a problem that appeared in an earlier version of python...
Explanation of lone surrogates:
In Unicode, a surrogate pair is when you create the representation
of a character by using two values. So, for instance, UTF-32 can cover
the entire Unicode space (since Unicode is 20 bits, although MvL says
it is really more like 21 bits), but UTF-16 can't. To solve the issue
for an encoding that cannot cover all possible characters in a single
value a character can be represented as a pair of UTF-16 values. The
high surrogate cover the high 10 bits while the low surrogate cover
the lower 10 bits. High and low surrogates can never be the same
since they are defined by a range of possible values and those ranges
do not overlap. So with the proper high and low surrogate paired
together you can make any possible Unicode character.
The problem in Python 2.2.1 is that when there is only a lone
surrogate (instead of there being a pair of surrogates), the encoder
for UTF-8 messes up and leaves off a UTF-8 value. The following line
is an example:
>>> u'\ud800'.encode('utf-8')
'\xa0\x80' #In Python 2.2.1
'\xed\xa0\x80' #In Python 2.3a0
Notice how in Python 2.3a0 the extra value is inserted so as to
make the representation a complete Unicode character instead of only
encoding the half of the surrogate pair that the encode was given.
Don't know if this is meaninful or not, perhaps this issue has to do
with a surrogate of another type in some form of object creation in Zope
itself.
Regards,
David

Hi David
Sorry, but I don't know where to place this bug. I thought i was the
only one who got it. I asked stephan on the sprint about the cause, he
didn't know either, so i thought it was a missconfiguration of my
deployment first. I can't reproduce it now.
I think it has something to do with files which are not that small e.g.
1MB and multiple requests, but I am not sure.
The twisted as default is really annoying, because the option for

I thought i was the only one who got it. I asked stephan on the sprint about the cause, he didn't know either, so i thought it was a missconfiguration of my deployment first. I can't reproduce it now. I think it has something to do with files which are not that small e.g. 1MB and multiple requests, but I am not sure. The twisted as default is really annoying, because the option for zserver implies that twisted is more stable.

Re[2]: [Zope3-Users] Debugger for Zope 3
Hi, If we are coming to commercial IDEs then Komodo is also a good choice for debugging. You just have to put it's dbgp module on the PYTHONPATH and use the below small script to avoid some irritating deprecation mesages. After this, you put brk() in you code and it will stop there. After it was stopped for the first with brk() the debugger will obey all 'normal' breakpoints. I think it supports threading also but never tried it. import zope.deprecation from dbgp.client import brk as dbgpbrk def brk(): zope.deprecation.__show__.off() dbgpbrk() Wednesday, April 26, 2006, 9:58:52 AM, you wrote: > On Tuesday 25 April 2006 08:27, Achim Domma wrote: >> I would like to start Zope 3 with the debugger, set some breakpoints in >> my modules and step through the code to learn more about Zope. > WingIDE's debugger is superb.
