Your rejection contains an assumption that the request won't make it to the application. Is that assumption testable? I guess so. I think it's relatively clear that the application server should insulate the application from malignant requests. The details probably depend on the HTTP implementation. zope.server, zope.app.twisted, Paster and others might deal with this differently. Looking at the interfaces between those parts of the application it makes no sense to have syntactially invalid requests end up on the application level.

Like everything else servers have bugs, so it can't hurt to test how your application would behave given certain server bugs. Right. IMHO this specific bug asked for would usually mean that the server breaks and can pass anything to the application. Whatever happens: the server needs to prepare a data structure to hand over to the application. If it can't do that, then there's nothing to test what happens with the application. I guess this kind of test (what happens with the application if it receives invalid data) needs to work around server/publisher components and inject data directly to application methods.

[Zope-dev] Help updating the copyright attributions
Hi, the ZF needs to finish updating the copyright attributions to state that the Zope code now belongs to the foundation. I've prepared some scripts to help with monitoring which packages need to be updated and also a helper to update most cases. It still involves manual work though, as we need to check out the individual branches, run the fixers, make some manual tweaks, run the tests, and check in. The test runners currently report a bit less than 600 of those and we're kind of stalling. I'd like to ask the favor that a few of us step up to help out and fix those over a short period of time. Tres' noted that each fix takes about 5 minutes. If we find 10 people where each of us did 10 of them on a day, we'd be done in about a week. So, I'm the first one to step up to do a hundred of them until Friday 2010-06-11. Who else is joining me?

[Zope-dev] Help! Need to extract files out of Data.fs!
Hiya, My company has been using a Zope server to store some reference material, but it has grown beyond belief, and I need to extract all the collected files (about 1.3 terabytes!) from the Data.fs into distinct files onto a different server. Unfortunately, I've run into some problems. Firstly, the FTP transfer process seems to be extremely slow, and if I try and transfer too large or deep a folder structure in one go then things grind to a halt. To beat this I've been carefully recreating the folder structure manually, and copying things in easier-to-digest chunks. Unfortunately, because I was a bit rushed over the weekend I have accidentally deleted about 130,000 files! I've tried going through the Undo procedure, but the idea of manually ticking 130,000 boxes (in pages of 20) and undoing them fills me with dread. So ... Please please /please/ does anyone happen to have the file format for the Data.fs file so that I could write a C program to extract and recreate the files and folders to another server? Or has anyone written such a program already? If so, I'll happily have your children if you can help me out! As it stands, I'm going to have to break it to the librarian (the poor man who has been collating all the reference material for the last six months) that I've lost half of his work, and blaming it on the poor FTP client in Windows seems a bit lame! If it helps: I'm running Zope 2.9.2 on a SuSE Linux box. I have full access to the Linux box ... and a large hammer, if I need it! :( Help!

Re: [Zope-dev] Help! Need to extract files out of Data.fs!
Kris, I assume you have a backup of the Data.fs. If you do, nothing is really lost. Have you compressed the Data.fs? There is an option in the control panel to do this. I can be run on a live machine, but you may not want to do so given the size of stuff. I'd do it on a quiet machine. This will remove any cruft you have in the Data.fs and will improve your speed of access somewhat, Things are probably slow because of swapping. Reducing the size of Data.fs may speed things up. Take a look at the documentation for the ZODB (Google is your friend). You could write a program in Python to simply open the ZODB and extract the files you need. It might save a bit of overhead. Remember 1.3TB is a large file and is going to take some time to process no matter what.

[Zope-dev] Help with two strange errors.
I'm pretty much finished with my WSGI-implementation for Zope2, and everything works just fine, even with twisted. Except that I get one highly bizarre test failure in PythonScripts! In my branch (but not in trunk) the test that you can't import certain modules in PythonScripts fails. It makes a python script that imports mmap. This fails in my branch but, and here is the bizarre part, only if you have twisted installed. Yeah, really. Any insight into this would be helpful... Also, the ZServer test seems to leave cruft behind. Possibly a thread, that the gets detected by the zope.server tests, because it will complain that a thread is left behind by those test, while if I skip the ZServer tests with -t '!ZServer' it works fine.

So far as the *database* is concerned, there's still no path from the root object to the BTree your __setstate__() created, so the BTree never gets committed. So the BTree is not registered with the database until _p_changed and a commit? After that first commit, the BTree is registered as reachable and then when just the BTree is _p_changed I get my changes saved. Right? Calling __setstate__ as a side effect of a persistent load does not, by itself, support making changes that persist. It apparently wasn't designed to, either (see the other msgs in this thread, particularly from ChrisM). I can understand the reasoning behind it, in the way that you don't want nothing to change on disk when you logically haven't called a mutating method on your object, just loaded it. But I do think it is badly broken to not save the changes when I have made additional changes to the state of the object after load time. Why not just take the performance hit and be done with it? What do other object databases do with schema migration issues, f.ex. GemStone? Now well, I believe I understand why this happens and that is a very good thing!

[Syver Enstad, wants to switch an attribute of a Persitent subclass
From PersistentList to an IOBTree]
[Tim, guessing]
Quick guess (untested, untried, ...
...
Perhaps shuffling the code around would work, a la:
Persistent.__setstate__(self, state)
articleList = state.get('_articleList')
if articleList is not None:
# make the BTree in local oidsToArticles as above, then
del self._articlelist
self._oidsToArticles = oidsToArticles
The thinking there is that then you've truly modified self, after self has
been activated.
Nope, sorry, not a chance. You have truly modified self then, but
__setstate__ is called by magic as part of activation (unghostifying), and
the activation machinery resets self._p_changed after it calls __setstate__.
So same result as your code: the in-memory version of self has the BTree,
but commit() doesn't change anything about self in the database (again
because self._p_changed is false -- and will be no matter what you try to do
in __setstate__()).
I was aware that __setstate__ doesn't allow me to commit my changes
after only loading the object into memory (__setstate__ is called). I
may have explained myself unclearly (not a native english
speaker/writer), the problem is that it won't save my changes when I
add more items to the _oidsToArticles BTree long after
__setstate__ time.
Example code:
# articleDb is an ArticleDb and has the __setstate__ method
articleDb = connection.root()['articledb']
for each in articleDb.articles() # loop through all article
print each
computer = Computer(1030)
articleDb.addArticle(computer)
connection.commit() # nothing is saved
Everything works smoothly until connection.commit(). The __setstate__
method correctly converts to using the BTree and the addArticle method
adds a new computer to ArticleDb.
If I instead create a new ArticleDb instance with the BTree instead of
using __setstate__ the new computer is saved as it should. In none of
the cases is articleDb._p_changed == True, but when the ArticleDb is
created cleanly instead of upgraded, commit works anyway.
Since this works if the object that holds _oidsToArticles is created
from scratch, it seems that ZODB isn't properly aware of the
_oidsToArticles attribute since it was created in __setstate__ instead
of in __init__. I would really like to know exactly what happens here
as the reason I am utilizing an object database is to be able to
refactor the database with a minimum of fuss, and I would expect
__setstate__ to allow me to make additional attributes in my
instances.

[Syver Enstad] I was aware that __setstate__ doesn't allow me to commit my changes after only loading the object into memory (__setstate__ is called). I may have explained myself unclearly (not a native english speaker/writer), I don't think that matters much: English instead of code is always ambiguous, even for native writers. the problem is that it won't save my changes when I add more items to the _oidsToArticles BTree long after __setstate__ time. Right. I tried to explain that in my first reply. It's expected. You have to get _p_changed set on your *object*. It doesn't matter how much you mutate new objects attached *to* the object you loaded, you have to get _p_changed set to 1 on the original object. Example code: # articleDb is an ArticleDb and has the __setstate__ method articleDb = connection.root()['articledb'] At this point articleDb._p_changed is not 1, and nothing you do later changes this fact. for each in articleDb.articles() # loop through all article print each It's obvious that this doesn't set articleDb._p_changed, right? computer = Computer(1030) articleDb.addArticle(computer) That adds something to the BTree that is bound to an attribute of articleDb, but still doesn't set _p_changed on articleDb (mutating the BTree does not mutate the object containing the BTree). So far as the *database* is concerned, there's still no path from the root object to the BTree your __setstate__() created, so the BTree never gets committed. If you do articleDb._p_changed = 1 at this point too, then your changes will get stored. connection.commit() # nothing is saved Right. As far as the persistence machinery is concerned, articleDb itself never changed, so there was no reason to store it. Since it didn't get stored, the BTree you attached to it in __setstate__ doesn't get stored either. Everything works smoothly until connection.commit(). The __setstate__ method correctly converts to using the BTree and the addArticle method adds a new computer to ArticleDb. The problem is that, while adding the BTree to articleDb did change (did set _p_changed to 1) articleDb, because that happened as a side effect of loading the object, the unghostification machinery clears _p_changed after __setstate__ returns. Then nothing you did after that set articleDb._p_changed to a true value. If I instead create a new ArticleDb instance with the BTree instead of using __setstate__ the new computer is saved as it should. Yes. If you had called __setstate__ *directly*, it would also work (contradicting the current minimal docs, but so it goes). The problem is that unghostifying by magic clears _p_changed. In none of the cases is articleDb._p_changed == True, When you create an object directly, it's not associated with a Connection (a jar), and some of the persistence machinery is sidestepped then. New objects only get into the database if you attach them to an object that's already in the database, and the latter object is marked changed. Think about that wink, and the purpose of the root() object will become clearer. but when the ArticleDb is created cleanly instead of upgraded, commit works anyway. Sorry, I'm not clear on what that means. In any case, it doesn't really matter how an object gets created, what matters is whether the persistence machinery sees a path to it from a changed object already in the database. Since this works if the object that holds _oidsToArticles is created from scratch, it seems that ZODB isn't properly aware of the _oidsToArticles attribute since it was created in __setstate__ instead of in __init__. Both ways set _p_changed *at the time* oidsToArticles is bound to the new BTree. The difference is that uhghostification deliberately clears _p_changed after calling __setstate__. I would really like to know exactly what happens here as the reason I am utilizing an object database is to be able to refactor the database with a minimum of fuss, and I would expect __setstate__ to allow me to make additional attributes in my instances. Calling __setstate__ as a side effect of a persistent load does not, by itself, support making changes that persist. It apparently wasn't designed to, either (see the other msgs in this thread, particularly from ChrisM). ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

There are enough ambiguities there to fill a whole thread wink. It is true that a call to __setstate__() alone doesn't affect the object's state in the DB. It needs more words. OTOH, I'd rather dream up a way to make object changes made in __setstate__() persistent, if desired. For example, __setstate__'s return value is ignored now. Perhaps we could say that if it returns True, then the object should be considered to be in the changed state rather than in the uptodate state. ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

[Zope-dev] Help: __getstate__ overriding
I have a Persistent derived class where I want to upgrade from using a

This seems to work fine, and I am adding more objects to
_oidsToArticles. The problem is that when I commit the transaction,
nothing is saved. I have tested the same code without __setstate__ and
then it saves just fine. What hoops does one have to jump through to
upgrade the state of a ZODB object?

Quick guess (untested, untried, just from eyeballing this snippet quickly):
nothing is marking self itself as being changed. The only things getting
changed are the throw-away in-memory 'state' dict, the throw-away in-memory
self.__dict__, and a throw-away in-memory BTree. The primary purpose of
p.__setstate__ is to activate a ghost, after which point p is in the
up-to-date state (i.e., not changed -- calling Persistent.__setstate__(self,
...) isn't going to mark self as changed, and nothing in the code above
modifies self itself). If self doesn't look changed, its state in the DB
won't change during commit(), and the DB will still reference your old
PersistentList.
Perhaps shuffling the code around would work, a la:
Persistent.__setstate__(self, state)
articleList = state.get('_articleList')
if articleList is not None:
# make the BTree in local oidsToArticles as above, then
del self._articlelist
self._oidsToArticles = oidsToArticles
The thinking there is that then you've truly modified self, after self has
been activated.

[Tim, guessing]

Nope, sorry, not a chance. You have truly modified self then, but
__setstate__ is called by magic as part of activation (unghostifying), and
the activation machinery resets self._p_changed after it calls __setstate__.
So same result as your code: the in-memory version of self has the BTree,
but commit() doesn't change anything about self in the database (again
because self._p_changed is false -- and will be no matter what you try to do
in __setstate__()).
This appears to be one of those severely underdocumented minefields. The
best older thread I found is here:
http://mail.zope.org/pipermail/zodb-dev/2002-March/002442.html
but it doesn't actually spell out something that works in the way you
want.
One possibility is to use any of these __setstate__ implementations
temporarily, in a one-shot database conversion script: load every object of
your subclass's type, and for each one obj, after loading it do
obj._p_changed = True
get_transaction().commit()
Note again that setting _p_changed *inside* __setstate__ won't do any good.
Note too that Jim Fulton has a recent proposal for Zope3 in this area:

This does not work as changes made in __setstate__ are not
explicitly persisted. Whether or not they become persistent
depends on whether the object is changed again outside __setstate__.

[Zope-dev] help me convert from j2ee to zope
Hi Ryan,
I am not certain if this is the right mailing list here, because
zope-dev is for the development _of_ Zope, not the development of
products _with_ Zope.
However if this thread starts to assemble a survey comparing Zope to
J2EE, this may be interesting for the Zope development, especially if
there are things in J2EE which may inspire Zope, or converse there are
Zopish ways which provide a better solution than J2EE for some problems.
I would like to stop developing with JBoss and convert to Zope.
I have been able to figure most things out using the Zope website but I have
a few questions...
The majority of my code was in EJB's. So I am trying to create Zope products
to replace them.
What kind of naming service is available within Zope? For example, how can I
get a reference to one object from another object within Zope? This would be
the equivalent of a local interface in J2EE. In JBoss I would use a session
bean as the remote user interface and it would manage entity beans. So in
Zope if I have a non-persistent object as the XML-RPC published user
interface, how can I have it access persistent objects within Zope?
Usually You should have some persistent object around by the Zope
framework when handling request. If doing an XML-RPC call You are already
talking to some persistent object given to You by the ZPublisher. I am
not sure what is the appropriate equivalent of a session bean in J2EE if
looking at Zope.
Inside any persistent object You should be able to
get other objects by calling unrestrictedTraverve('/path/to/object') if You
know the path to the object. Alternatively You could use a catalog to
look up objects if You are not sure where the objects are ... as the
catalog is a persistent object itself this means You need a globally
available catalog for Your application which You know You can look up in
a certain location ...
How can I create new objects programmatically in Zope? In J2EE I would get
get a home interface to a bean and then call a create method on it to create
the bean. I know how to create new objects using ZMI in Zope, but I need
objects to be created through remote calls from clients. For example if I
had objects that represent tasks in Zope, I need the clients to be able to
create and delete tasks. How do I do that?
There are factory methods for nearly all persistent objects. They are
registered in the context.registerClass call in the __init__.py of the
corresponding product (normally). These methods then are available via
the manage_addProduct attribute on every folder object; i.e. for
adding a Page Template (which is a class defined in the PageTemplates
Product) programatically You say:
folder.manage_addProduct['PageTemplates'].manage_addPageTemplate('template_id',
template_content)
where folder is the object which should contain the new page
template, and template_content is a string containing the contents of the
new template.
I've read all the documentation I can find on the web site, so if I've
missed something please point me to it.
Another source of inspiration is to install products which seem to do
something similar what You want and try to figure out how they did it.
(I personally prefer Silva for rather obvious reasons ;)
Cheers,
Clemens

Hi, I would like to stop developing with JBoss and convert to Zope. I have been able to figure most things out using the Zope website but I have a few questions... The majority of my code was in EJB's. So I am trying to create Zope products to replace them. What kind of naming service is available within Zope? For example, how can I get a reference to one object from another object within Zope? This would be the equivalent of a local interface in J2EE. In JBoss I would use a session bean as the remote user interface and it would manage entity beans. So in Zope if I have a non-persistent object as the XML-RPC published user interface, how can I have it access persistent objects within Zope? How can I create new objects programmatically in Zope? In J2EE I would get get a home interface to a bean and then call a create method on it to create the bean. I know how to create new objects using ZMI in Zope, but I need objects to be created through remote calls from clients. For example if I had objects that represent tasks in Zope, I need the clients to be able to create and delete tasks. How do I do that? Are there any other gotchas that ex J2EE developers can tell me about switching to Zope? I've read all the documentation I can find on the web site, so if I've missed something please point me to it.

Hi all, We are facing a small issue in formulator. Suppose we have a fiels which is repetitve in nature for ex name1 , name2, name 3.depending on the user input. If we want to validate these name we have to create required fields i.e name1, name2 etc..in validator in advance. Can we do the same using only one field in formulator i.e name and put all the derivatives of it like name1 , name 2 as a array to name. in that case, we can have more control in field handling and so would not have the headache of pre formation of the fields which may susbsequently increase later on.

RE: [Zope-dev] Help!!
This is a wild guess. A common problem on UNIX is to run Zope initially as the root user. In that situation, even if you declare an effective user via the -u switch, the log files and pid files are written as the root user. It will run fine. Then later on, someone stops the process. You attempt to start the process as the effective user. Because the initial log and pid files were written as the root user, the process cannot open them for writing and Zope will not start. As I said, a wild guess, but might be your problem here (especially as you don't seem to see anything useful in your log files). - C On Thu, 2003-08-28 at 12:53, Todd Loomis, (SAIC) wrote: What have you done to verify that zope isn't running?

It uses the Catalog, which is based on ZODB, and it puts a Catalog instance into the main FileStorage, which is undoing and versioning. It then proceeds to do writes to the database when it appears that all you're doing is reading a pre-existing page. If you're in a version at the time, a set of objects will be written into the Catalog and into other places in instance space that have version.

The structure that's getting corrupted looks something like: 299, (300, (301, (302, (303, ( 304, ( 3, c_o_s ) ) ) ) ) ) (nested tuples) I'm wondering if anyone can think of somewhere inside Zope that generates this sort of structure? c_o_s is a string we use in our code as a property, a database column, and a REQUEST variable. As far as we can tell, it's not something being generated by our code...

Re: Was:([Zope-dev] HELP PLEASE)
Hi, After viewing all log-files, i have found out, that everytime when a SQL-Method was called and the SQL-Method takes several minutes to return a result then a erro code 13 was raised. Last time i change the DA from ZPygres to ZPsycopg, because of the error code 13, but that was not the problem. The problem seems that if a SQL-query takes several time, then the error is raised.

[Zope-dev] help! I've broken refresh
And life is just not the same without it! I had auto refresh working fine until recently. Today, if I change a py file I see the pyc file being regenerated, but only when I do a manual refresh. And I do not see the effect of the changes until I do a full zope restart. FWIW, several things happened lately: - I cleaned out some shadowed older product versions from /usr/lib/zope/lib/python/Products - I experimented with ZEO (but I'm not running it now), and - I rearranged the product quite a lot. __init__.py was changed, modules were split up, imports moved around, and there is a new sub-package tests which also contains a refresh.txt.

[Zope-dev] Help! - I want to understand Acquisition...
Hi, First of all I'm converting an existing (and working) Zope product from version 2.1.4 to 2.3.1 and I'm having the following problem when trying to run the (new) converted version. In a dtml document which is run many times for different types of objects ie. something like dtml-in " ... " . . . IMG ... src="dtml-var expr="getIcon(REQUEST)"" ... . . . /dtml-in where it iterates through a list of objects, I get mixed results which I don't understand. When it works the getIcon function returns the path (using the REQUEST namespace) and icon for the particular object type and then this gets rendered as expected. But when it fails the icon for the type does not get rendered at all (understandably). After some debugging (ie. print statements) I found that when it failed the REQUEST namespace was not passing what I expected (it was empty), and when I tried to print the namespace it printed the following; Special Object Used to Force Acquisition So the python function (getIcon()) was expecting the REQUEST object but actually getting (it seems) is a derived (and unexpected) object, and failing when looking for particular attributes. I don't understand this behaviour (why it works for some and not others and why it worked in a previous version of Zope) and therefore how to fix it. Any help or pointers on the above or other relevant issues to upgrading older products would be appreciated.

[Zope-dev] Help, please!!! __call__ problems with DTML templates
Today is not a good day:-( I've just spent 2 days trying to force
__call__ to render my product properly, got every error possible at least
seven times, and wasted last night working out what was wrong with Refresh
(I was calling refresh on the wrong product. Duh!).
Please, please, please, can someone point me in the right direction.
I have a class called Element which has three components:
1. purpose: a string describing the element's role (rendered as structured
text)
2. template: a string that is rendered to display the element (DTML)
3. Element inherits from Folder so it can contain sub-elements which can be
included in the template
For example, suppose A is an element that contains a sub-element B (i.e. B
is A.B)
Ahas template 'Element A contains dtml-var B'
and purpose 'Contain B'
Bhas template 'element B, which contains nix'
and purpose 'Element with no subelement'
Now for the tricky bit: "dtml-var A" needs to be rendered one of three
possible ways depending on a variable in the REQUEST. So __call__ needs to
return one of
- case a: the purpose property (as structured text) wrapped in []
- case b: render the template, with sub-elements properly rendered
- case c: render the template, with sub-elements wrapped in [] showing
their purpose
Then 'dtml-var A' must be rendered in the three cases as:
- case a: '[Contain B]'
- case b: 'Element A contains element B, which contains nix'
- case c: 'Element A contains [Element with no subelement]'
To do this, I need to write my own __call__ method since __call__ is what
detemines how objects gets rendered in DTML (is this correct?)
def __call__(self, client=None, REQUEST={}, RESPONSE=None, **kw):
With this, I discovered that 'dtml-var A' gives client=None and REQUEST={}
while
'dtml-var "A(_,REQUEST)"' gets client=_ and REQUEST=REQUEST.
But I cannot for the life of me, work out how to do what I need. In
particular:
1.) How do you magically get the DTML context from 'dtml-var A' without
having to resort to 'dtml-var "A(_,REQUEST)"' in the templates?
In the __call__ methods of different classes, I've seen some code like:
'if REQUEST is None and not kw: REQUEST=self.REQUEST' (from
Catalog.py)
and other code like
'if hasattr(self, 'aq_explicit'): bself=self.aq_explicit else:
bself=self' and
'security=getSecurityManager() security.addContext(self)'
(from DTMLDocument.py)
I can't see any consistency in what these classes are doing, so I don't know
what I need to do.
2.) How to convert an arbitrary text string into rendered DTML inside a
python product method?
How do you get the object's properties, REQUEST and acquisition context all
in the namespace?
I've been trying code like:
template = 'span class="purpose"dtml-var purpose
fmt="structured_text"/span'
dtml = HTML(template, globals())
rendered = dtml(self, REQUEST)
but this doesn't work. All the example classes I've seen (such as
ZWikiPage.py in ZWiki) use DTMLDocument as their base class so can call
DTMLDocument's __call__ on themselves as in
text = apply(DTMLDocument.__call__,(self, client, REQUEST, RESPONSE),
kw)(ZWikiPage.py, line 135)
This doesn't help me because I don't have DTMLDocument as a base class.
Looking through the source for DTMLMethod etc is not very clear because lots
of "apply(__call__,(...),kw)" calls are all mixed up with acquisition code.
3.) Do I need to write a custom tag (dtml-element A) to get this
behaviour?
So, if anyone out in Zope land can help me, I'll be eternally grateful. I've
exhausted my patience looking through the NIP mailing list archives, the
How-Tos and the Zope site and need to have something to demonstrate on
Thursday.
Thanks in advace,
Stephen
P.S. ChrisW, searching NIP for "__call__" returns every message with 'call'
in it, which is not quite the same thing!
