Note though that you can't set it to an arbitrary value, because the ZODB will set it to the current time when the transaction commits. If that's all you want, it's sufficient to do something like: some_image._p_changed = 1 (and then, if you're running in eg. a zopectl debug prompt, import transaction; transaction.commit()) -- Paul Winkler http://www.slinkp.com ___ 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 )
[Zope] TraversalError in custom TALES namespace during Five tests
I've implemented a custom TALES namespace that works fine when tested in the browser, but blows up in doctests. Anybody seen behavior like this? It appears that during the test, my adapter is looked up fine, but later when we try to traverse to the method, we end up with a zope.security._proxy._Proxy wrapper that hides the existence of my methods. Just to reiterate, the same code *works fine* when running Zope for real, and I only see this failure during tests. Here's the tail end of a test / pdb session: 41 def traverse(self, name, furtherPath): 42 -> subject = self._subject 43 __traceback_info__ = (subject, name, furtherPath) 44 attr = getattr(subject, name, _marker) 45 if attr is not _marker: 46 return attr 47 if hasattr(subject, '__getitem__'): (Pdb) n > /home/pw/builds/slinktopp.openplans.org/builds/20081210/opencore/lib/zope/lib/python/zope/traversing/adapters.py(43)traverse() -> __traceback_info__ = (subject, name, furtherPath) (Pdb) n > /home/pw/builds/slinktopp.openplans.org/builds/20081210/opencore/lib/zope/lib/python/zope/traversing/adapters.py(44)traverse() -> attr = getattr(subject, name, _marker) (Pdb) p subject (Pdb) p name 'member_title' (Pdb) p subject.member_title *** AttributeError: This appears to indicate that the OpencoreTales instance itself is fine, but the security wrapper is preventing attribute access.

On a stylistic tangent: combining "nocall" with "python" doesn't make
any sense, and I don't believe it has any effect. Nocall's purpose is
to prevent implicitly calling the object traversed at the end of a
*path* expression.
Also, don't use tal:content when you don't actually want to insert the
result of the expression. The most common idiom I've seen when calling
something purely for side effects is to abuse tal:define:
Or, better, put the define in a tag that actually serves a purpose and
you can leave out the omit-tag as well:

Yes, you can write a custom virtualenv bootstrap script as documented here: http://pypi.python.org/pypi/virtualenv#creating-your-own-bootstrap-scripts You can then distribute just your bootstrap script, and all somebody has to do is download and run it (assuming they have python).

I don't think doing it in zopectl will do what you want. AFAIK, the cache that method minimizes is the in-memory object cache. zopectl runs in a separate process, which will have its own cache; so calling manage_minimize() in a zopectl script will not affect the running Zope server. Instead you could write a script that uses wget or python's httplib or similar to connect to the running Zope server and send the same request that submitting the form in the ZMI would send. None of this has anything to do with caches on disk, so I may be misunderstanding what you want. The only disk cache I know of that's relevant to ZODB is the ZEO client cache, which I don't believe is affected by manage_minimize().

[Zope] Call for new ZSyncer maintainer
Hi folks, ZSyncer (http://sourceforge.net/projects/zsyncer) is in need of a new maintainer. Once in a while I get a question about ZSyncer. Sadly I have to face the fact that I have not been actively maintaining it for quite some time: I haven't used ZSyncer at all for over a year, have made no commits in that time, and no releases for over two years. So, while I'd be happy to do some paid work on ZSyncer if your employer really needs something done, I've clearly abdicated my leading role in ZSyncer's community (is there one?). Anybody care enough about it to step up? If so, contact me off-list. I would be happy to provide support during a transitional period. Summary of current status: * There are several fixes in CVS that should probably be released as 0.7.2, but I'm not sure if they're adequately tested. * Tests pass under zope 2.9; untested with 2.10 or trunk. * The code is, in my opinion, badly in need of refactoring and cleaning up. * There is a suite of ZopeTestCase tests. Should probably be broken up into smaller cases. -- Paul Winkler http://www.slinkp.com ___ 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 )

I've never tried ZSyncer with Zope 2.10; I don't have any guesses what your problem is. Have you tried syncing between two 2.10 instances? In general, you move data from 2.X to 2.X-1 at your own risk, whether using ZSyncer or the import/export tab in the ZMI. I've been the "official" ZSyncer maintainer for about 5 years now, but honestly I've barely touched it since 2005, since in its current state it works well enough on the rare occasions that I need it. If somebody else cares enough about ZSyncer to maintain it, please contact me. Otherwise, to be crassly honest, I'm unlikely to do any ZSyncer-related work unless somebody pays me to do so. -- Paul Winkler http://www.slinkp.com ___ 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 )

I've never tried ZSyncer with Zope 2.10; I don't have any guesses what your problem is. Have you tried syncing between two 2.10 instances? In general, you move data from 2.X to 2.X-1 at your own risk, whether using ZSyncer or the import/export tab in the ZMI. I've been the "official" ZSyncer maintainer for about 5 years now, but honestly I've barely touched it since 2005, since in its current state it works well enough on the rare occasions that I need it. If somebody else cares enough about ZSyncer to maintain it, please contact me. Otherwise, to be crassly honest, I'm unlikely to do any ZSyncer-related work unless somebody pays me to do so. -- Paul Winkler http://www.slinkp.com ___ 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 )

That sounds like a really bad idea. From the Zope 2.5.1 release notes: * Zope requires Python 2.1 (Python 2.2 is currently *not* supported) You should NOT assume that warning was put there for no reason :-) Also, there's not a whole lot of expertise in this community on building for Windows; we seem to be a linux/unix-heavy crowd. You'd better stick to the binary releases and not mess with them, unless you can find a bona-fide expert to help you. Anyone? :-) Meanwhile you might try migrating a *copy* of your Data.fs to Zope first to Zope 2.6.4 (still uses Python 2.1.x) and then to Zope 2.7.7 (uses Python 2.3.x). FWIW I recall 2.5 to 2.6 being a painless upgrade. I think 2.7 was a little more involved. The most likely problem to watch out for is security-related issues: your code might accidentally rely on a security weakness that was subsequently tightened, so you get permission denied at unexpected times until your code and/or configuration is fixed. Install and turn on VerboseSecurity, it's a big help with things like that. -- Paul Winkler http://www.slinkp.com ___ 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 )

Close but no cigar. Dictionary-style item access does NOT use
acquisition:
foo['bar']['baz'] works iff bar is in foo and baz is in bar.
Object-style attribute access DOES use acquisition:
foo.bar.baz works if bar is in (or can be acquired by) foo, and baz
is in (or can be acquired by) bar.
Finally, restrictedTraverse() is your friend:
foo.restrictedTraverse('bar/baz') works like foo.bar.baz

It's been a while though, so things could have changed.) I spent several hours recently to import a .zexp of a Plone 2.0 site. Got nowhere. One suggestion I got (which I wasn't able to follow) was the following. If you have access to the original server, try this: 1) Make a full backup of the entire ZODB, eg. using repozo.py. 2) Set up a new Zope instance with all the same products installed, using your new backup copy of the ZODB. 3) Go into the ZMI for this new instance, and delete everythign EXCEPT this plone site. 4) Pack the database to get rid of all the other stuff. Or make a new clean backup. There. You now have a Data.fs that contains only your Plone site. Instead of importing the .zexp, just mount the database at the appropriate path.

I don't think ZEO is a panacea that magically makes apps faster in all cases. If you're not CPU-bound, the added network overhead and increased chance of write conflicts might be a net loss. Based on everything he's said so far, it sounds like Gaute still has plenty of headroom on his CPU. As for the other benefits of ZEO: - multiple ZEO clients does allow you better responsiveness with high concurrency, but you can also try increasing the number of threads to get the same effect without the added network overhead. - not using ZEO means that Zope is a single point of failure.

Yeah, for some definition of "approaches". I think a more realistic minimum would be number of threads * number of ZODB writes (since each write potentially invalidates one cached object per thread).

Based on your activity graph, you do indeed have a lot more reads than writes. What's the CMS based on? Plone? Silva? Chris W. had a good point about the catalog. Do you have blobby data in the ZODB? (large images or files)? Those tend to play havoc with zodb cache activity, since one OFS.Image is stored as an arbitrarily long chain of small persistent objects. So whereas a Plone Document or a Page Template needs only one entry in the cache, an Image might need hundreds. -- Paul Winkler http://www.slinkp.com ___ 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 )

You can do whatever you like, but you're not likely to find many
people still running 2.5 on this list... so you might get less useful

Not with FileStorage. Only one process at a time can open a
FileStorage.
If you would use ZEO instead, then it would be possible. Your code
above would then be modified to use ClientStorage instead of
FileStorage. But I don't know exactly what the code would look like
in zope 2.5, I haven't run that version in years. I vaguely remember
needing a custom_zodb.py file to set up ClientStorage. If you would
upgrade to a more recent Zope (2.7 or later), then ZEO is available
out of the box just by uncommenting some lines in the example
zope.conf. And you would also get a script at bin/zopectl that's
perfect for this kind of job. Your own script would be invoked as an
argument to zopectl, like:
./bin/zopectl run path/to/my/script
... and you would get the root application automatically set up for
you and bound as "app".
But you still need to use ZEO.

Moral of the story is: don't do insane things with your system clock, the results are undefined. More generally, don't try giant shotgun workarounds ... a) if you don't know what the effects will be b) if you don't really understand your original problem c) if you don't have a backup in case your "solution" causes a bigger problem Flem, I'm sorry this happened to you, but sorry to say your attempted solution was a really bad idea and it's not really fair to blame the software for that. The best thing you could do is restore from the backup you made before you messed with the system clock. If you didn't make one, you may have to truncate the database to a transaction previous to when all this happened. Make another backup copy of Data.fs before doing that, of course. The basic idea is: find the position in the Data.fs file that contains the first transaction that occurred at your "in the future" date, and delete the rest of the file after that point. This is assuming you haven't already packed the database and thrown away the old transactions you want to recover. There isn't really an "official" way to truncate as far as I know, and I don't remember the details, but the links here might help (look under the word "truncate"): http://wiki.zope.org/zope2/ZODB Also check the archives of the zodb-dev mailing list, there has been some recent discussion of ways to truncate the database file, the topic was "roll back filestorage zodb to a certain date". lib/python/ZODB/fsrecover.py may be helpful for finding those transactions. -- Paul Winkler http://www.slinkp.com ___ 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 )

My approach might be good if:
- the logic for looking up articles is more complex than can be
comfortably expressed using apache rewrite rules, and/or
- the logic for looking up articles requires state that's internal to zope.
You could instead follow Andreas' suggestion and use a through-the-web
Script. It might look something like:
article_id = traverse_subpath[-1]
data = context.get_the_data_somehow(article_id)
return data
Your URLs would then look like:
http://example.com/folder_id/script_id/article_id
Note that naming the script index_html doesn't really help, because
http://example.com/folder_id/article_id wouldn't invoke the script.

Another option is that the object at /articles could be an instance
of a class that looks something like:
class MyArticleContainer():
def __before_publishing_traverse__(self, unused, request):
# Save the rest of the path as 'traverse_subpath'.
request.set('traverse_subpath',

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

In other words: The ZODB may be there but you can pretty much ignore

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
> Globals.DTMLFile).
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.

Zope isn't really hung - it's just using so much memory that you're "forever" waiting on disk I/O to handle all those pages. The system should recover eventually if there's no more load; but unfortunately the typical case is that once you start swapping badly, user requests keep piling up in the queue, so things only continue to get worse. I'm impressed at your stats though. I've never had a box with 8 GB of RAM, much less got Zope to use up all of it :-) Have you tried the "debug spinning zope" recipe? http://www.zopelabs.com/cookbook/1073504990 that might give you a clue how you got into this state. unfortunately since the whole system is swapping like crazy, working at the shell is probably no fun either :-) P.S.

I would add 4) the front-end server can provide "sanitizing" of requests from buggy or malicious clients. A search of the mail archives will find many people advising the same thing. I recently experienced it myself. I wasted a lot of time recently trying to find out why Zope was leaking memory on XML-RPC requests *only* from a certain client. The leak was small, but under load, Zope would exhaust the system's memory after a few days. I could never determine the cause, nor could I provoke the leak with other clients. Then one day, the client switched from one Java XML-RPC library (an old version of the Apache xmlrpc library) to another (Redstone I think), and immediately the symptom stopped. Zope's memory usage became quite stable. Nothing else was changed. A good, battle-tested reverse proxy in front of Zope should help protect against that kind of thing. -- Paul Winkler http://www.slinkp.com ___ 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 )

My feeling about the DTML-vs-ZPT debate is that it can basically be reduced to the following chart: FEATURE | DTML | ZPT| +---+-+ potential for | | | confusion due to| Lots | A little| implicit magic? | | | +---+-| "familiar" syntax? | Yes | No | +---+-| round-trip with | Hell no | Maybe, with | an HTML designer? | | some pain | +---+-| Useful for | Yes | Not really | non-X(HT)ML?| | | +---+-| Prevents invalid| No| Yes | markup? | | | +---+-+ So, you have to ask yourself which of the above you care about for the projects you work on. With Zope, I am typically doing HTML or XML, usually with somebody else doing the design. For me, ZPT has nice advantages. OTOH, sometimes we're doing ZSQL so we use DTML syntax for that.

Has this been replaced? I've been working with zope since 2000 and never heard of pyUrlQuote. So I strongly suspect it's something local to your application. - what kind of object is context in this case? maybe it's expected to be an instance of something that has a pyUrlQuote method, but you're calling this code in a different context? - maybe pyUrlQuote is a Python Script or some other persistent object, and you're in some other part of the folder tree where you can't acquire it from parent folders? hard to guess with so little information... sorry. -- Paul Winkler http://www.slinkp.com ___ 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 )

That's not how you set an environment variable in any of the bourne-style shells (sh, bash, ksh).

You're looking for bobobase_modification_time, for hysterical raisins. Note however that it's updated on *any* transaction commit that touches the object in question, which often isn't granular enough for apps that care about things like mod time.

Aside from that, and the problem with '#quotes' as Andrew pointed out,
absolute_url() is just not safe to use with restrictedTraverse(), since
the url takes virtual hosting into account and thus may add or remove
parts of the path. This technique tends to work fine during local
development and then as soon as you deploy to a server with virtual
hosting configured, boom, everything breaks. No fun.
So, Don't Do That.
See http://www.plope.com/Books/2_7Edition/AppendixB.stx#2-394
When creating paths for use with restrictedTraverse(),
you should always use getPhysicalPath() instead.
In this particular case, I suspect you don't even need to do that.
Try:
tal:define="root python:here.restrictedTraverse('index_frame.pt')"
which can be spelled a bit more simply as:
tal:define="root nocall:here/index_frame.pt"

I have no idea what's causing your problem, but this raises
red flags for me: if two people upload sources at the same time,
you'll have problems here. If you really really must read/write
files on the filesystem, either use locks or use python's

Are you just using saxon for xslt processing? If so, IMO using an
external process for that is severe overkill. Get lxml and try
something like this:
from lxml import etree
style = etree.XSLT(etree.parse(some_file_object))
transformed = style.apply(source_data)
but again, this doesn't address your immediate problem :)

XML-RPC is not very helpful here. As usual, its extreme simplicity is
both a blessing and a curse.
The specification, http://www.xmlrpc.com/spec , specifies POST with
content-type of text/xml, and that's all; so you really can't
distinguish XML-RPC from any other xml POST just from the header.
I suppose the publisher could cheat a bit and look in the body for the
required element. If missing, it can't be XML-RPC.
It would be more reliable if some configuration was required to specify
when XMLRPC is expected, and when not. But that would break Zope's
longstanding promise that XMLRPC is supported "for free", always,
automatically.

In Python, anytime you call "unbound" methods (i.e. by referencing a class rather than an instance), you need to pass an instance - in this case, self - explicitly. For example: def manage_beforeDelete(self, item, container): CatalogAware.manage_beforeDelete(self, item, container) OrderedFolder.manage_beforeDelete(self, item, container) But if your actual code looks like your example, you should have gotten errors due to missing arguments. -- Paul Winkler http://www.slinkp.com ___ 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 )

On the surface this isn't really a zope question, it's basic Python. You're looking for the getattr() builtin function. For example: [EMAIL PROTECTED] ~ $ python Python 2.4.3 (#1, Jul 27 2006, 13:07:44) [GCC 3.4.6 (Gentoo 3.4.6-r1, ssp-3.4.5-1.0, pie-8.7.9)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> class Foo: ... bar = 1 ... >>> foo = Foo() >>> foo.bar 1 >>> path = 'bar' >>> foo.path Traceback (most recent call last): File "", line 1, in ? AttributeError: Foo instance has no attribute 'path' >>> getattr(foo, path) 1 Of course, Zope 2 has to complicate things a bit :) Zope's ObjectManagers, such as Folders, also allow you to use dictionary syntax to access their children. So you can do foo[path] as well. There is a semantic difference, though, in Zope 2: * attribute access like getattr(foo, 'bar'), or foo.bar, falls back to using acquisition to look for 'bar' in foo's parent folders. * Item access (like foo['bar']) does not use acquisition, so you'd get an immediate KeyError if foo does not contain the named object. I recommend using item access in all cases except when you know for sure that you want to use acquisition. Acquisition bugs can be big time-wasters - e.g. accidentally acquiring a slightly different object than the one you wanted to use, because the one you expected to find happens to be missing, or a site admin renamed it, or some such. -- Paul Winkler http://www.slinkp.com ___ 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 )

You'll need to use an external method (or write a simple product).
Then you can use httplib or urllib2, or the python wrappers for curl
(I found curl worked in some weird firewall configurations
that httplib didn't).
But you mention XML. If the remote system is XML-RPC, you'll
want to use python's excellent xmlrpclib, which makes
rpc calls look just like local calls:
remote = xmlrpclib.ServerProxy('http://somewhere/something')
result = remote.someMethod('param1', 'param2')
