RE: [Zope-dev] FileUpload and blob on Windows
Hi Leo,
I'm not familiar with the Zope side of the world at all, so this may be
completely useless...
However, if one tries to consume a NamedTemporaryFile and then open its
generated blob before closing the tempfile, Windows complains:
import ZODB.blob, tempfile
f = tempfile.NamedTemporaryFile()
b = ZODB.blob.Blob()
b.consumeFile(f.name)
b.open('r')
Traceback (innermost last):
...
IOError: [Errno 13] Permission denied:
'c:\\buildout\\var\\tmp\\tmpsuykkc'
...
unless we use some non-portable win32 code to allow writing and
reading to the same file simultaneously.
I'm not sure exactly what you mean by simultaneously, but assuming you
just need the ability to read and write to a file, you already can. Does
this behaviour help?
import tempfile
f = tempfile.NamedTemporaryFile()
f.write(hello)
f.seek(0,0)
f.read()
'hello'
I can easily see it might not - as soon as the file is closed you have
(obviously) lost it.

Does this behaviour help? import tempfile f = tempfile.NamedTemporaryFile() f.write(hello) f.seek(0,0) f.read() 'hello' Why are you using a NamedTemporaryFile? If I'm right the goal is to store the file stream from the upload directly in this file and copy this file over to the real directory location. This means you can cut down the amount of read and write file data, right? Why not use a own file class like: class TMPFile(file): Temorary file. This temporary file can remove a file in request.close() form the file system. def release(self): Release the object in the requests (_held) list. if self.name is not None and os.path.exists(self.name): os.unlink(self.name) You can move such a file with shutil.move(self.tmpPath, targetPath). I implemented such a file upload accelerator. With this beast I was able to upload a ubuntu vmware image with 950 MB in about 75 seconds to Zope3. And this with a memory usage below 50 MB. It really rocks. Note; I implemented this on windows and it works well.

Hmm. The Python docs already mention this problem for Windows. To avoid copying, we'd have to adjust the publisher not to use a NamedTemporaryFile, but actually use a regular temporary file that gets deleted when the publisher decides to.

Re: [Zope] zope 2.9.6 stops servicing requests
Look for the DeadlockDebugger and install that and follow the instructions. Hopefully it can help you debug what Zope is doing when it's not responding but still ticking. Perhaps you've got some dead connections to the database that refuse to timeout.

[Zope] ZMI in zope 2.10.5 broken
Hi everyone, I'm new to Zope and have just installed Zope2.10.5. I have created a new Zope instance in my home folder and then browsed to my servers ip address at port 8080 and logged into the ZMI. This is the problem, the top and main frames of the ZMI render perfectly and I can navigate to the links in the main window, however, the tree menu in the left frame does not load. Instead I get this error: Error Type: NameError Error Value: global name 'util' is not defined I have had a look through the mailing lists and googled for hhours and have found no indication as to what could be causing this. The only clue I have is that when I click on the 'help' link in the main frame the left frame of the window fails to render, even though it is a completely different url. I have tried this in both Mozilla and IE and on several different computers, one on XP and one on Vista. Some information about my setup: I am running an ubuntu 7.10 server, installed both Zope installations from the .tgz files on Zope.org. Python version 2.4.4 please tell me what extra information I can provide, I have zero experience with Zope and am finding it pretty tough to learn, so I know nothing about standard log files or debugging.

[Zope] Package recommendations (?) for minimal ZCA environment
All: I figured I would survey this list for recommendations of zope packages that have minimal dependencies -- specifically for non-web, non-ZODB ZCA applications. My criteria for this minimal environment: 1. No ZCML, ZODB, or zope.app.* dependencies. 2. Egg available in cheeseshop; svn is okay too (e.g. zope.cachedescriptors trunk does not require ZODB; PYPI egg does at the moment). I will use zc.buildout and virtualenv for deployment environment. 3. Not specifically targeted at web applications only. Currently, I'm using zope.component, zope.interface, zope.schema, zope.datetime, zope.event, and a related but small set of dependencies installed from PYPI. Background: I'm working on a set of components for working with mass-media content that are to be generically useful across multiple environments, application frameworks (web and non-web), etc. The core of these components depends on some zope 3 libraries, but my goal is to keep dependencies to a minimum. A superset of this minimum framework would be used to deploy components to specific application environments including basic automation scripts to move content from one system to another, middleware applications exposing these components over XML-RPC, web applications in Z3, Django, and Plone/Z2. Any recommendations appreciated. Maybe compiling a list like this is helpful for the community to reach out to non-Zope python developers too -- makes the technology more approachable.

Some of the ones that we've compiled (visible via http://svn.repoze.org or http://dist.repoze.org): repoze.vhm (virtual hosting services) repoze.retry (retry a request when an exception is encountered) repoze.tm2 (transaction management, depends only on the 'transaction' module and zope.interface, see also http://repoze.org/tmdemo.html ... note that repoze.tm depends on all of ZODB, repoze.tm2 depends on only the smaller packages but does the same thing, at the expense of not being compatible with ZODB 3.6) You might also take a look at repoze.zope2 to service Zope/Plone requests via WSGI: http://static.repoze.org/misc/developingwithrepoze-zope2.pdf and check out repoze.org in general, as your goals seem to closely align with its.
