Re: [Zope-dev] Packing (still) hosed in 2.6.2?

2003-08-15 Thread Anthony Baxter



Woohoo! Fixed. I created an empty file, then used copyTransactionsFrom
to copy all transactions across. This patched the backpointers. fsrecover.py
should probably get some smarts to do something like this as well, but I've
spent far too long on this problem already... :-/

from ZODB import FileStorage
infilename='/app/zope/dev_csr_server/recover/Data.fs'
outfilename='/app/zope/dev_csr_server/recover/Out.fs'
outfs = FileStorage.FileStorage(outfilename)
infs = FileStorage.FileStorage(infilename)
outfs.copyTransactionsFrom(infs)


I have some small patches to fsdump that outputs expected prev records
alongside the actual ones, is this useful enough to check in?

[Zope-dev] 501 NotImplemented in Zope 2.7 beta1

2003-08-15 Thread Jim Washington

I have been noticing a few 501 Not Implemented errors in the ZMI in 
2.7 beta.

The ones I have encountered are fixed by changing method=get to 
method=post in the html/dtml forms in e.g., Aqueduct.py.

I do not know the proper fix.
Also, this is weird enough (and perhaps merely a beta issue) that I 
could not decide the proper category in the bug collector or even what 
to search on to see if it had been reported previously.

So, consider this an FYI should anyone want to take a stab at fixing it 
or reporting it to the collector.

 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.

Ok. The original error, reformatted for clarity:

ZODB.fspack.CorruptedError: 
/app/zope/dev_csr_server/recover/Data.fs:9200838:
data record does not point to transaction header: 
17391715 != 9200760

Here's the 3 transactions (one before, dead one, one after). There's
definately a screwed transaction there.

So, fixing this. fsrecover.py doesn't do the right thing, unfortunately.
It just leaves the broken record alone. I'm not sure if making fsrecover
handle this class of error is useful...

It should be simply a matter of walking through the transactions, and
patching the one that's busted. Or alternately, simply skipping it.

I'll look into fixing this now. More in a bit.

[Zope-dev] DBTab/ZEO configuration in Zope2.7 beta1

2003-08-15 Thread Tino Wildenhain

Hi,

looking thru code, examples and documentation,
it seems DBTab is included into Zope2.7.
Now how to configure it? Should I use
a dbtab.conf file as it was with 2.6?
The mkzopeclient.py with -z option
just builts a custom_zodb.py which does
not seem to be very 2.7-alike.
Shouldn't that configuration not be in zope.conf?
I cannot find relevant tags for the
zodb_db tag.
Are there any places I could look into for enlightement?

Regards
Tino Wildenhain

mkzopeclient -z should go away.  You should use the zope.conf file to
configure mounted databases.  Unfortunately I haven't had time to
include adequate examples in the sample config, but it might help a bit
to look at the lib/python/Zope/Startup/zopeschema.xml file.

Just a step in between:

there seem to be the definition of
the relevant section of zope.conf.

zopectl debug yields the following:

tf._setObject('session_data', toc)

AttributeError: _setObject

strange. Perhaps the temp_folder isnt mounted?

There is no reference of the tempstorage in the above definition file...

Re: [Zope-dev] DBTab/ZEO configuration in Zope2.7 beta1

2003-08-15 Thread Chris McDonough

This is because the default is to mount a temporary storage at
/temp_folder.  Since you overrode the default, you need to specify the
tempfolder storage in the config.

Something like this (untested) as an additional zodb_db entry should
work:

zodb_db temporary
  temporarystorage
name sessions
  /temporarystorage
mount-point /temp_folder
/zodb_db

Re: [Zope-dev] DBTab/ZEO configuration in Zope2.7 beta1

2003-08-15 Thread Tino Wildenhain

Hi Chris,

thank you. By the time I got it working when I first
used filestorage, bootet zope so it created all folders
as it wants and then stop zope and use that Data.fs
for ZEO. Then I was able to mount the zeo as /
I'll investigate this further and provide the examples.
For now even the fallback seems to work.

Storage type temporary seems to not mentioned anywhere,
but I'll test this too.
Kind regards

Re: [Zope-dev] why cant i import types

Add a folder called GlobalModules in your Products directory and put in
that folder a file called '__init__.py' with this content:


from Products.PythonScripts.Utility import allow_module
allow_module('types')


with this you can't use from types import * but you can use the second
form from types import ListType, StringType, ...
