Re: [Zope-dev] Zope.app() dance with 2.7
Chris,
I took the code from zopectl that is uses to do the debug thing and
scripts now work. Here is the code...
import os
if (os.environ.has_key('ZOPEVERSION') and
os.environ['ZOPEVERSION'] == '2.7'):
from Zope.Startup.options import ZopeOptions
from Zope.Startup import handlers as h
from App import config
opts=ZopeOptions()
opts.configfile=os.path.join(os.environ['ZOPE_HOME'],'etc/zope.conf')
opts.realize()
h.handleConfig(opts.configroot,opts.confighandlers)
config.setConfiguration(opts.configroot)
from Zope.Startup import dropPrivileges
dropPrivileges(opts.configroot)
You need to set ZOPEVERSION to 2.7 for it to work. Is there a better
way to figure out the current zope version? It would be nice if the
Zope module had a __version__ that you could check (or is there one
somewhere else that I missed).
I'm running this against the code from cvs but I bet it would work with
2.7.0b1

[Zope-dev] UndoSearch Timeout
Hello, We have a ZODB which is about 12 - 14 gigs when packed. We use FileStorage, and when anyone clicks Undo eventually times out. This is better now that the undoLog does not lock the database. However if there are not enough transactions to fill the batch Undo is useless. So, everytime we upgrade to a new version of Zope I patch FileStorage.py to add a timeout. Used to be 3 seconds when the ZODB locked, now I've bumped it up to 10 seconds. Has anyone else had this problem? Would adding the timeout, possibly set by an environment variable, be considered by the maintainers?

RE: [Zope-dev] Packing (still) hosed in 2.6.2?
I don't recall that any of the pack bugs that we fixed caused this sort of error. My first guess would be that the file is a bit damaged, perhaps in a way that the old pack did not check. Can you run fsdump.py and see if that output sheds any light. It will give you a detailed text summary of all the transactions and data records. You could use the dump to figure out if, for example, the two numbers in the error message are indeed transaction header locations.

Re: [Zope-dev] FileUpload questions
I have been looking at the FileUpload class defined in HTTPRequest.py but am still a little confused about how it works. When a form is submitted with an input type=file ..., where are the contents of the uploaded file stored? Is it automatically stored in the ZODB, or is it stored in memory until some other code (like that in Image.py) stores it? The reason I am asking is that I want to store uploaded files on the file system instead of in the ZODB.

Being new to Zope and Python, it is not clear to me exactly how to go about this. Don't bother mucking around in the core. The right way to do it is to use a Product that stores data on the fiesystem, acting as a facade. Look at LocalFS, ExtFile/ExtImage, ExternalFile, and possibly APE.

Re: [Zope-dev] FileUpload questions
Its handy enough to implement.
lets say your file parameter is called 'file'...
#os_uploadCacheImage is a Zope External method.
if request.has_key('file'):
context.os_uploadCacheImage(context.PATH_CACHE,
request['file'], request['file'].filename)
#co-responding implementation for zope external method
os_uploadCacheImage
def uploadCacheImage(self, basePath, file, filename):
cacheFile = open(basePath + / + filename, wb)
cacheFile.write(file.read())
cacheFile.close()

I have been looking at the FileUpload class defined
in HTTPRequest.py
but am still a little confused about how it works.
When a form is submitted with an input type=file
..., where are the
contents of the uploaded file stored? Is it
automatically stored in the
ZODB, or is it stored in memory until some other code
(like that in
Image.py) stores it?
The reason I am asking is that I want to store
uploaded files on the
file system instead of in the ZODB. (We are running
Zope behind an Apache
web server, so the uploaded files will be placed under
Apache's document
root so they can be served directly by Apache.) Being
new to Zope and
Python, it is not clear to me exactly how to go about
this.
Don't bother mucking around in the core. The right way to
do it is to
use a Product that stores data on the fiesystem, acting
as a facade.
Look at LocalFS, ExtFile/ExtImage, ExternalFile, and
possibly APE.
Probably LocalFS or ExternalFile are most interesting to
you.

Re: [Zope-dev] why cant i import types
For security reasons many of the standard libraries are not allowd to be used in Zope. Types is one of them. You can declare a library as save for use in a python script. How I can not say without consulting the documentation. Robert Am Friday 15 August 2003 04:18 schrieb Declan Shanaghy: Can someone tell me why i cant import types into my python script in CMF?
