[Zope] Re: Zope 2 and Zope 3
Geoff Gerrietts wrote: [some paragraphs about scaling which I can't really comment on] As for source control, I figure all of your code (DTML, yuck) is in the ZODB. This went out of fashion a long time ago, most serious development happens on the filesystem (in Python packages) which can obviously be source-controlled very well. A good deal of the code is in the ZODB, because it's (yuck) DTML documents, yes. We have another sizable chunk that lives on the filesystem. The challenge in managing the build/deploy process has been trying to find a way to keep those two conjoined. I suspect that any dependency on the ZODB at all is likely to be considered an impediment, and my quick eyeballing says it's not gone or even really optional under Zope 3 (but I'm sure we could work something out.) The ZODB is still there in Zope 3, but Zope 3 is much less dependent on it. In fact, there are people who are using Zope 3 without any ZODB instance at all, but directly talk to a relational database. Currently this requires a bit of hacking, but our good man Chris Withers has expressed interest in making the next release of Zope 3 more flexible in this regard. What's already possible is to have a minimal ZODB with only one persistent object: a SQLObject or SQLAlchemy container. That's a container (e.g. like a folder) whose items aren't persisted in the ZODB but come from a relational database. You seem to already have come to the conclusion that having code live in both the filesystem and the ZODB can be painful. I think a good first step for you would be to migrate your remaining ZODB-based code to the filesystem. That not only makes deployment easier, you're also free to refactor it then (e.g. using Zope 3 idioms). In the long run, this also means saying good-bye to things like External Methods because they require code on the filesystem and configuration in the ZODB. Regarding "oh you'll hafta start over", it's pretty much true, if you want to switch to Zope 3. But nobody says you have to. You can do it incrementally by porting some of your app's functionality to Zope 3 components step by step (as mentioned already, most work in Zope 2). Big projects like Plone aren't rewriting their whole codebase either, but new development is completely Zope3-based. Their target platform still is Zope 2, though. "You'll hafta start over" is only ever true in degrees, though, and I'm still trying to figure out what the degrees are. The business logic will still be the same. Can we hack together a DTML processor that allows us to export the DTML documents to the filesystem and publish them from there? Maybe, I don't know. Did someone else already do that? Don't know that either. How dramatically will our products need to change? Probably 75% of our Python code is written in a bastardized form of ExternalMethod; we might be able to leverage that unfortunate architectural choice to significant advantage during our porting phase. These are the kinds of questions I have, and I think the answers probably aren't easy or someone would have offered them up. It is certainly possible to execute filesystem-based DTML (using Globals.DTMLFile). It's hard to say how much your products will have to change without knowing the codebase. If you have external methods, it shouldn't be too hard to refactor this code into components in "proper" Python modules. To make things easy, the external methods could stay at first, for backwards compatibility. I would take this one step at a time (that's at least what everybody else seems to do and it looks like it's working out for everybody). Someone's going to need to learn enough Zope 3 to answer the questions. I'm not sure it will be me, but maybe. :) Well, whoever it'll be, there are books (e.g. http://worldcookery.com) and trainings (e.g. http://trizpug.org/boot-camp/camp5) that should help with the learning :). -- http://worldcookery.com -- Professional Zope documentation and training Next Zope 3 training at Camp5: http://trizpug.org/boot-camp/camp5 ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

The following script adds a new folder with a user folder inside it and then adds a user to the user folder.

This works fine in a Zope 2 / Five world too. We have apps that have
nothing in the ZODB but a Z*DA instance. Then we have zope 3 views
and adapters that acquire that instance and use it to talk to the
database, using ZSQL to build the queries. We haven't drunk the ORM
cool-aid yet. :)
In other words: The ZODB may be there but you can pretty much ignore
it if you don't need it :)

Here's my off-the-cuff attempt at "How To Safely Move A Big Legacy App
Out of the ZODB".
First, get and install FSDump (google for it).
Add a Dumper to a folder containing DTML (it works recursively on
child folders too), configure the Dumper, click the "Save and dump"
button, and voila, there's your code on the filesystem. It'll store
properties too, in files named like *.metadata.
Then you need a way to use the stuff from the filesystem.
FileSystemSite would be ideal, because it understands those .metadata
files: http://www.infrae.com/download/FileSystemSite
Using it is a bit non-obvious if you're not familiar with CMF, from
which it was extracted. You'll need to create a minimal Product on
the filesystem that consists of:
- a directory in Products, let's call it Products/mystuff
- an __init__.py at Products/mystuff/__init__.py that looks like this:
from Products.FileSystemSite.DirectoryView import registerDirectory
registerDirectory('mysubdir, globals())
- a subdirectory at Products/mystuff/mysubdir. Put the files and
directories you dumped in here.
That's it. Restart Zope, add an instance of Filesystem Directory View,
and you'll be prompted for the directory to choose; the only choice
will be the "mysubdir" you registered above. Click OK and you're done.
Check this new Product into source control and rejoice.
One gotcha - files ending in .dtml will be treated as DTML Methods,
not DTML Documents. So if you relied on the semantic difference
between those, you will have some issues to sort out.
Another gotcha - you'll need another plan to deal with those External
Methods, since AFAIK neither Dumper nor FileSystemSite will handle
them.
One expedient if slightly tedious technique would be to just move the
External Method files out of Extensions/ and into
$INSTANCE_HOME/lib/python/. Then use calls to allow_module() so they
can be imported by through-the-web code (google will tell you more
about that). Then, delete each external method from the ZMI and in
its place add a Script (Python) with the same id. Such a script would
have a body something like:
from my_ext_method_module import myExternalMethodFunction
return myExternalMethodFunction(arguments)
Once that's done, those scripts can be Dumped into your filesystem
code, and all the DTML that includes calls to them should work.
A final gotcha - if you have ZClasses, I can't help you :)
At this point, you have the same application you started with, it's
just on the filesystem. Not as clean as a rewrite, but a hell of a
lot more expedient - faster and less risky.
Next you'll want to start adding regression tests to your product
(ZopeTestCase and Zelenium might be useful tools). Then you have a
safety net so you can confidently start refactoring as needed. *This*
is when you can start thinking about rewriting stuff :-)
I'd put this email somewhere on zopewiki.org, but it seems to be down
at the moment (Bad Gateway).
> It is certainly possible to execute filesystem-based DTML (using

Right. But that's a bit of a pain when you have dozens or hundreds of
DTML methods and your first priority is just to get stuff out of the
ZODB and into source control without breaking anything.

Very useful. I've based my system on the first link because I didn't need to use POSTs, I just add ?foo=bar to the end of the URL and get it as normal. I added the ability to load a list of urls and element ids one after the other, then only activate the submit button at the bottom of the page when the whole form was loaded.

[Zope] problem with input elements and unicode/utf-8
Zope: 2.10.2 Python: 2.4.4 I am not sure if this is a zope problem or a browser problem or a lack of my understanding of webservers and/or utf-8 & unicode but here it is: I have a page template with a form and a textarea input element. The value for the element comes from a database (MySQL) field. The database field contains utf-8 encoded text (includes the bullet and registered characters). When the page is displayed in Firefox (version 1.5.0.9) it displays fine. However when the page is displayed in IE 6 (or 7), it shows garbage characters for the bullet and registered characters. What I find as strange is that if the same field is displayed as just text (i.e. just in a td element rather than in an input element) it displays fine in IE. My page template has the following headers: Firefox reports the page encoding as UTF-8 with meta: content-type text/html; charset=utf-8 Input element: I have also tried adding accept-charset="utf-8" to the form element I have been able to fix the problem by adding this to my zope.conf: HTTP_ACCEPT_CHARSET utf-8 I don't understand why this "fixes" the problem or if it is the correct way to resolve this.

You would access the ZODB directly (under *nix with "bin/zopectl debug";
for Windows, there are equivalent solutions (search the mailing list
archives)).
You would activate there a function that recursively traverses
your Plone instance (maybe using "OFS.FindSupport.ZopeFind"),
detects objects valuable for you (probably "CMFFile" objects) and
store their content ("str(obj.data)") into the file system.

Previously the application was running in Zope 2.8 without this problem. I
have been making various changes to the application to make it work with
2.10 (fixing unicode errors, etc) but the database data has not changed
(has always been utf-8) and I don't think the way the input element is
generated has changed.
If it makes a difference, the page header (tal:define="dummy
python:request.RESPONSE.setHeader('Content-Type', 'text/html;;
charset=utf-8');") is something I have added recently (in conjunction with
the upgrade). Previously only the meta http-equiv ... was on the page.
