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.

[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__.

RE: [Zope-dev] Help: __getstate__ overriding
[Syver Enstad]
I have a Persistent derived class where I want to upgrade from using a
PersistentList to a BTrees.IOBTree.IOBTree.
_articleList is the old Persistent list
_oidsToArticles is the new IOBTree.
def __setstate__(self, state):
articleList = state.get('_articleList')
if articleList:
oidsToArticles = self.makeBTree()
for each in articleList:
oidsToArticles[each.oid()] = each
del state['_articleList']
state['_oidsToArticles'] = oidsToArticles
Persistent.__setstate__(self, state)
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.
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.

RE: [Zope-dev] Help: __getstate__ overriding
[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__()).
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:

Syver Enstad wrote at 2004-5-28 12:41 +0200:
I have a Persistent derived class where I want to upgrade from using a
PersistentList to a BTrees.IOBTree.IOBTree.
_articleList is the old Persistent list

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?
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__.
Use an explicit conversion script instead...

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?

would it make sense to make the help system still allow searching but do storage in a mounted zodb ? cheers kapil On Saturday 09 March 2002 10:55 am, Chris McDonough wrote: There is no way to fix this? What other problems are there with the help system? Not that I can think of. Other problems with the help system are presentation, mostly. Would it somehow be possible to make the helpsystem ignore versions? No, unfortunately. 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. This is a bad pattern, and the only way to fix it is to prevent it from happening, which requires some helpsystem architectural changes that amount (IMHO) to a rewrite. - C ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

Stephen Simmons wrote: 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? Give your class a class attribute of isDocTemp=1. This tells the DTML method calling machinery that you want to receive the namespace as REQUEST as the third argument to your __call__ method. There was a thread on this in zope-dev on and around 26 September, subject "more __call__ ..." 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) Your method will usually get called with its third argument as the namespace, or REQUEST. However, sometimes, it may just be called with a "self" argument. The code in Catalog.py is falling back on getting the REQUEST out of the self argument, if it is not explicitly passed a namespace to work with. I can't see any consistency in what these classes are doing, so I don't know what I need to do. Most developers would like more consistency here :-) I'm hoping that all this will be much much clearer for Zope 2.3. That doesn't help much for now though. 2.)

dtml = HTML(template, globals())
rendered = dtml(self, REQUEST)
Here's an except from my Python interactive interpreter:
import DocumentTemplate
my_dt=DocumentTemplate.HTML("""dtml-var "1+a)
my_dt(None, {'a':4})
'5'
The object my_dt is callable, and takes the arguments (client,

used above.
If you're trying this, make sure you have the PYTHONPATH environment
variable set to /your/zope/directory/lib/python

You can write a pretty simple external method to walk your Zope object
heirarchy looking for DTML Methods and DTML documents, then altering the
syntax. Shouldn't take more than an hour to write and debug and test and
document, if you've written stuff in Python before.
I'm off to a meeting for a few hours, but harrass me later and I'll send
to the list a proof-of-concept external method to get you started.

follows.
* Use at your own risk
* No warranty implied or given
* Use on a copy of your main Zope site
* Back up data.fs three times before starting
* Not guarenteed not to spin your processor and never terminate
* Run on a copy of Zope in debug mode (-D) to see the print statements
* Barely tested, if at all
