[Zope-dev] RFClarification: Security on Product Attributes
Hi, If I have the following lines in a Python Product: def __init__(self, id): """initialise a new instance of product""" self.id = id self.title = 'Title!' self.anInt = 0 self.aString = 'testing' Are these attributes protected by the security machinery? If so, how so? Can I read them? I think the answer is yes for anInt and no for aString. Don't know the mechanics of title and id, I'm guessing they're going to be special cases whatever... Are they protectable by permissions? I do hope so although my experience is that, at best, it's not necessary, which is contrary towhat I thought the new security policy was. Should they have to be protected by permissions? Probably...

[Zope-dev] __call__ hell :-(
:-( Right, I have a Python product with a __call__ method that is (hopefully) going to be used to render a navigation tree. To do this (and have the tree expand in the right places) I need a list of objects that need to be expanded. I'm currently using the following expression to get this list: objects = copy(self.REQUEST.PARENTS) objects.reverse() Now, to this I need to append the PARENTS[0-1] object, if you see what I mean. In DTML, it would be this(), but I'm stumped as to what I should append in Python. self is just the navigator object. If I redefine __call__ as def __call__(self, client, REQUEST) I just get a TypeError: Error value: not enough arguments; expected 3, got 1 If I use a safer signature def __call__(self,client=None) then client is always None, and so not what I'm after at all. I had a look at DTMLMethod.py and PythonMethod.py to try and get a clue btu just got very scared. Can someone please help me out here? cheers, Chris PS: If there's a totally different way to get the containment list of objects that need to be expanded, I'd love to hear it :-) ___ 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 )

How would this differ from getPhysicalPath(ob)? Is it just that
getPhysicalPath won't contain any acquired objects, if you see what I
mean?
I think something ob.getPhysicalPath() is probably what I want, but if
you read my post titled "__call__ hell :-(" you'll see I can't actually
find the object I'd need to call getPhysicalPath() on. I think it's the
'client' I'm looking for but I have no idea for to get that in the
__call__ method of my python product.
Any ideas?
(if it helps, the __call__ method is executed as the result of a
dtml-var myObject which appears in standard_html_header)

[Zope-dev] ZServer and ftp port-1 data channel
It appears we still have a problem with ZServer's port 20 data
channel response behavior with the latest released Zope (Zope 2.2.1
(source release, python 1.5.2, linux2) and Active Mode ftp clients.
In particular, when you select the port-1 behavior, medusa can't
seem to bind to port 20 when port 21 command channel is specified.
"ftp_server.py" line 278:
if self.bind_local_minus_one:
cdc.bind (('', self.server.port - 1))
After verifying that self.server.port - 1 = 20, the current behavior
is that medusa simply hangs at the bind statement. If there was a
permissions problem my understanding (and experience) is that one
would receive:
socket.error: (13, 'Permission denied')
and not a process hang. Any idea why medusa simply hangs on the
attempted bind?

Is this the 'L-1' thing? Where the server-side port for the data
channel is supposed to be '20' (I think that's right). I made some
changes to the server to support it, but it's disabled by default;
because
1) most people don't care
2) it has the potential to break the whole server
in certain situations, depending on the OS. Other ftp servers
get all acrobatic trying to Do The Right Thing, IMHO not worth it
in medusa's case.
See the 'bind_local_minus_one' variable of the ftp_channel class.
This should be checked into the medusa cvs, but I'll attach a copy as
well.

Shane Hathaway writes:
wu-ftpd solves this by temporarily restoring root privileges and
actually tries more than once to bind to the correct port, which is
ugly.
(Sam writes:)
It's even worse than that. Here's a quote from proftpd-1.2/src/inet.c:
/* According to one expert, the very nature of the FTP protocol,
* and it's multiple data-connections creates problems with
* "rapid-fire" connections (transfering lots of files) causing
* an eventual "Address already in use" error. As a result, this
* nasty kludge retries ten times (once per second) if the
* port being bound to is INPORT_ANY)
*/
(...)
In other words, it's just bound to fail. A forking server can afford
this sort of persistence, but in medusa I think it'd be overkill; I'd
have to set up event timers, an object to maintain the retry state,
etc [this alone it might add 50% to the size of ftp_server.py]

I'd have to agree with Sam, it's just not worth the effort.

Active mode is becoming deprecated and it would take extraordinary effort for Medusa to support it 100%. The most used FTP clients these days are browsers such as Netscape and IE. They always run in passive mode; in fact you can't turn off passive mode. "wget" runs in passive mode if you use the --passive-ftp option. Almost every FTP client you find on freshmeat or download.com supports passive FTP, including WS_FTP and FTP Explorer. At least in Mandrake 7.x, even the standard ftp command supports passive mode. After logging in, enter "passive".

[Zope-dev] New Proposal: PersistentBlob
Hi all, Yesterday I put up a new proposal on the http://dev.zope.org site that documents my vision of PersistentBlob. The main idea is the be able to mark blocks of strings (text or binary) content for storage in a file system as individual files. (Or blobs in a relation table.) The two motivations for this are keeping a ZODB FileStorage small and exposing blocks of string content to external processes (i.e. full-text indexing). Thanks for taking a look. John -- John D.

[Zope-dev] Proposal: Local ZClasses
Problem:
Encapsulation for plugable brains and other purposes are too hard.
ZClasses are a global kind of thing that requires going into a separate area
of the site which you have to have permission to use.
Also I find that I evolve my solutions. I will produce something in
folders that works for what I want and then try and generalize it into
ZClasses later. However if my solution in the folders itself wants to use
classes then the only choice I have is external methods or ZClasses.
Solution:
Local ZClasses:
A ZClass that can be created in any folder and is available with the
acquisition path. It can then be used for pluggable brains with sql methods
also where the Class can be reached in the acquisition path.
e.g. I have a few fancy display methods that I use for display results of
a sql query for getting phone contact info e.g. create a vCard for each
entry. I create a ZClass with a property sheet matching those returned by
the sql method. I create my display methods within this ZClass. I associate
the sql method with the ZClass. I call the query with dtml-in. Within the
loop I have access to the ZClasses methods.
Second solution:
Prototype objects:
A folder is an object with methods etc. A ZClass is not much different
except that it has a constructor and a list of the properties that are
always there. With a bit of syntax we could make a local folder into a local
ZClass. We just need a method that says, using this folder as a prototype,
create me a new object. e.g. dtml-call
"REQUEST.set('myobj',_.new(users_class, name='Dylan'))".
This would effectively make a new non persistent object that inherits from
the prototype folder I guess. This could be done with plugable brains as
well by just specifying the folder as if it was a class and then new objects
would created for each row.
If you enable the ability to make these prototype objects persistent then
you get the side effect that you can create symbolic links. You can access a
whole other acquisition path using inheritance. In fact you could have a
property of a folder which is its inheritance objects which you could change
over its life time. In fact any object could have this property could affect
an objects behavior without moving the object or modifying its underlying
classes. Also it would mean overload any kind of object. Just create a
folder that inherits from an object or class and add methods.
Personally I think the second solution has a lot of merit. What do others
think?

Re: [Zope] multiple ZOPE ...
We host zope using mutliple installations of zope. Yes, that's what we do for our "Professional" Zope hosting. For "FreeZope", you just get your own folder, and it lives under http://freezope.nipltd.net/yourplace. We have a standard list of products, and we don't allow people any more. It is better this way because then the clients can control which products they have installed, they can tweak their products without bothering anyone else, they can stop and restart zope whenever they please...the basically have full control. You can't do that with more than one client using the same instance. All the advantages you mention, plus you can let them upgrade their Zope version when they need it. We want to upgrade FreeZope to 2.2.x at the moment, and its something we need to be cautious about. There are a lot of people on FreeZope, and the move to 2.2 can break a fair number of things. Given its this painful on a free service, I'd hate to be trying to upgrade a shared server that had paying clients. Yes it does use a fair bit of memory, but you would expect your client to pay for it accordingly. Its also requires a fair number of configuration steps (raise the OS account, install Zope, configure Apache, configure MySQL, setup DNS, setup log analysis etc.), which takes time - although we'll probably automate some or all of this at some point. If you allow your customers shell access to the machine you also need much greater security awareness than you'd have for just a normal firewalled web server.

[Zope] PyGreSQLDA
Has anyone had significant speed issues using the PyGreSQLDA? It seems like I'm only getting one DB connection at a time. Is this an issue with the DA, with Zope, or am I doing something wrong?

Shouldn't it still be able to establish multiple connections, though? I guess I'm confused as to how it works. Thought I was using it right, but if I execute a query through Zope it takes a few milliseconds unhindered.

[Zope] [Fwd: Zope Question]
Hey gang, I'm posting this question here because I know a while back some people had mentioned they were using Zope. I'm trying to start using it, getting used to the DTML and all the other stuff. I can get it running with my Apache server, and that's all well and good. But I have these two questions which I can't seem to find answers to in current Zope documents and help. 1. How do I get the server process to run as a daemon? I've tried the one script for an rc process I found on a site, but my server just hangs and I never get a command prompt back. All other processes I've ever run at startup are either designed to be daemons, or have a specific switch to add to the program name. 2. OK, this is kind of two part. First, where does Zope actually store all of the directories and files you create for a site. If I have a fake directory as the "trigger" for the persistent CGI process, than where does it actually store this pages I'm creating? As an example, following the install instructions that comes with Zope, I've set Apache to send every request for /zope to the FastCGI process running in the background. That directory does not exist in my htdocs directory. Where is this stuff going? Two, can I get Zope to answer the general requests for a site (like www.bms.school my internal server and fake domain.) Rather than having to specify a directory, it would just send all requests to Zope. But to take that one step further, if I had user accounts set up with the /~username convention, would this stuff be able to pass through Zope and actually go to those directories?

- Original Message - From: "Ryan Booz" [EMAIL PROTECTED] To: "Comp Ed List" [EMAIL PROTECTED] Sent: Monday, September 25, 2000 3:03 PM Subject: Zope Question Hey gang, I'm posting this question here because I know a while back some people had mentioned they were using Zope. I'm trying to start using it, getting used to the DTML and all the other stuff. I can get it running with my Apache server, and that's all well and good. But I have these two questions which I can't seem to find answers to in current Zope documents and help. 1. How do I get the server process to run as a daemon? I've tried the one script for an rc process I found on a site, but my server just hangs and I never get a command prompt back. All other processes I've ever run at startup are either designed to be daemons, or have a specific switch to add to the program name. Removing the -D (debug) switch from the z2 line in start.py will cause Zope to release control of the terminal from which it was started. 2. OK, this is kind of two part. First, where does Zope actually store all of the directories and files you create for a site. If I have a fake directory as the "trigger" for the persistent CGI process, than where does it actually store this pages I'm creating? As an example, following the install instructions that comes with Zope, I've set Apache to send every request for /zope to the FastCGI process running in the background. That directory does not exist in my htdocs directory. Where is this stuff going? In the "ZODB" (Zope Object Database). See http://www.zope.org/Members/mcdonc/HowTos/gainenlightenment for some nuggets. This is a tough one to wrap your head around when you first get started. Two, can I get Zope to answer the general requests for a site (like www.bms.school my internal server and fake domain.) Rather than having to specify a directory, it would just send all requests to Zope. But to take that one step further, if I had user accounts set up with the /~username convention, would this stuff be able to pass through Zope and actually go to those directories? I don't think I'm making this question clear, but I don't know how else to state it right now.

[Zope] Zope Dies with FastCGI
I have the following set-up under which Zope occasionally dies. Zope 2.2.2 (same happened with 2.2.0 and 2.2.1) RedHat Linux 6.2 Apache 1.3.12 - with fastcgi/2.2.8 and OpenSSL/0.95a I'm running Zope with Fastcgi and using Apache rewrite rules to redirect all URLs that contain "manage" to https. It seems to work fine except on occasion Zope will die with the following error: "ZServer uncaptured python exception, closing channel FCGIChannel connected 127.0.0.1:2198 at 87195b (socket.error:(32, 'Broken pipe') [path_to_Zope/Zserver/medusa/asynchat.py|initiate_send||211] [path_to_Zope/Zserver/medusa/asynchat.py|send|274]) This doesn't always mean the server is dead but it is the only error I can trap with debug turned on.

Re: [Zope] Nasty subtle security bug - Me Too
Shane Hathaway wrote: Martijn Faassen wrote: General problem description: For a ZClass instance/external methods that is only viewable by users with a particular role, the view operation fails if that role is only added to a user in a place deeper in the folder tree than the folder where the External Method/ZClass instance was defined. This occurs when the 'view' is occuring in the acquisition context of the folder. It succeeds if the role is added to the user in a folder higher in the tree, at or above the folder where the external method or ZClass instance is defined. This sounds 100% correct. When checking security, acquisition context is ignored. What matters is *containment* (which is also accessed through the acquisition machinery, but in a special way: aq_inner). A user can only access objects that are defined in a container where the user is granted access. How come it does work with DTML methods then? I can access a DTML method 'foo' defined in the root folder that is only accessible with role A, even if role A is only added to me in a subfolder (from this subfolder). You probably don't really want to change it to use context instead. It would open a mile-wide security hole. Depends on how you reason. I was reasoning context based -- I should be able to execute something in the context of the current folder, if I have the right role to do it. That's exactly how it works with DTML methods, so I didn't expect external methods to be different. If you're opening a mile-wide security hole with external methods, then why not with DTML methods? The view operation fails with a reauthentication request in Zope 2.1.6 (so authentication exception raised presumably). In Zope 2.2.2 the failure is a NameError for External Methods, and reauthentication for ZClass instances. Am I missing something terribly obvious, or is this a rather huge bug that's been unnoticed for a long time? I assume it *must* be a bug as DTML methods behave in a different way. I also want it to be a bug, as I don't like this behavior. It makes it very hard to delegate responsibility. The difference is a result of the change in the way security is handled. It now gets a NameError because the name lookups skip over entries to which you're disallowed access. That logic can be very puzzling, but you might try the ZDebug product which helps you make sense of it. Okay, I'll try that. I still don't see why DTML methods are different. Could you explain that? That's what initially caused much of my confusion; the DTML methods behave as expected, but call external methods that *don't*, which have *exactly* the same security settings. Note that this policy does make acquisition rather useless for delegating of responsibility, unless you're either using DTML only, or are coding for anonymous only.

[Zope] String manipulation
"how can I manage it to cut a string.
for example:
a string property (testtext) with 500 words.
but only want to give out 20 characters of tis text."
Python sequence slicing syntax can be done with DTML, like so:
dtml-call "REQUEST.set('first_20_char', '_['some_long"string'][:20])"
dtml-var first_20_char
wher the '[:20]' means from the begining of the string, through the 20th
"slice".
One thing to be aware of is that the positions start counting at 0, and are
best thought of as falling "between" the individual characters, like so:
a b c d e f g
0 1 2 3 4 5 6 7
So the 20th position ('slice') is just past the 19th character, if the first
character is counted as 0.

[Zope] Exceptions, exceptions...
Hi, Yesterday I posted the message below, and I'm happy to inform all that the problem was basically just my advanced braindeath. I decided to triple check everything today, after a good night of sleep, (and a so so day of real work) and found out that the variable I could swear was being used inside the external method wasn't really. It would be referenced only after the location where the exception was triggered, so it being undefined didn't trigger an error as I had naïvely expected. I just had forgotten to set it explicitly in the page that called the external method. The good news is that the exception machinery then seems to work exactly as one would expect, and quite wonderfully at that. Many thanks to all those that developed such a great system, Ramiro. Hi, I have a DTML document with the following structure: dtml-var standard_html_header dtml-try dtml-call "my_external_method(REQUEST)" p Report that everything was ok and wait for ack. form method=POST action=index_html input type=submit value="OK" /form dtml-except MyException p class="warning" Warn about problem found by external method. form method=POST action="treatError" input type=submit value="OK" /form /dtml-try dtml-var standard_html_footer and it works wonderfully, to be honest I thought it was quite uncanny to define and raise an exception inside the python module, and having it caught by the DTML document. Now, to improve the treatment of errors I need to refer, inside the dtml-except block, to some variables that were defined in the REQUEST variable (I'm pretty confident of this because I used them inside the external method), but it seems that the original REQUEST variable is no longer set inside the dtml-except block. Is this correct? What actually happens (in simple terms, please :) when an exception is thrown? I also tried the very few other tricks I know with DTML (dtml-with "_.namespace..." outside the dtml-try block, plus some other voodoo) but couldn't get it to work, either. Should I return these values as error values with the exception? I can do it if this is the only option, but I'm already using the return value for information related to external method things, and I'd rather not mix the two ``domains'', so to speak.
