[Zope-dev] 2 Zopes
Hi, Can anyone tell me a way to get Zope Objects from the first Zope-Installation to the second. I need this because i have to program a Product to putting data into different Zope Installations from one point of the Web. My boss want this way because he want a central point for data input, where the data are of different type and therefore they have to stored in different locations( different Zope Installations) My idea is to use ZPublisher.Client, but i don't find a way to use it. thanks as ___ 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 )
[Zope-dev] Security and Acquisition?!
Toby Dickenson wrote: Zope security is context based: Users can be defined in a subfolder and only have access under that folder, they can also be given local roles for a given folder. The role:permission mapping is set per-folder. Any security aware object needs to know its context. Yeah, I think I get it now *grumble* *grumble* ;-) That said, I think Shane said that Zope security is predicated a lot on Acquisition. Now, can I get the solution I'm looking for by mixing in Aquisition.Explicit, still have the security stuff work and not have the DisplayClass acquiring attributes I don't want it do? Yes, you will need to set Acquisition.Acquired for the necessary attributes. Anyone know what those attributes are? Maybe someone could knock up a new class in Acquisiton: Acquisition.SecurityAcquire which does this but is like Acquisition.Explicit for everything else? Wanting to make an object non-acquiring may be a danger-sign of some other problems. If the correctness of your program depends on the absence of certain attributes (acquired or otherwise) then you need to take extra care over PropertyManager-like features, which might allow a user to add the critical attribute. Yeah, I know :-S But these are very specific classes that exist for no longer than the duration of serving a single page request, and it'd just be nice to know that they're not going to acquire and fluff they shouldn't... cheers, Chris ___ 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 )
[Zope-dev] RE: Security and Acquisition?!
Anyone know what those attributes are?
Heres a good trick: add this method to your class to see which attributes it
is asked for, but doesnt implement.
def __getattr__(self,id,reg={}):
if not reg.has_key(id):
print `id`
reg[id]=id
raise AttributeError(id)
But these are very specific classes that exist for no longer than the
duration of serving a single page request, and it'd just be
nice to know
that they're not going to acquire and fluff they shouldn't...
An alternative approach: apply tighter security to the method that
constructs these objects, and leave the objects themselves completely open.

Re: [Zope-dev] Large file support
How does this differ from Local FS? cheers, Chris [EMAIL PROTECTED] wrote: I have been building an "ExternalFile" class which stores the body of the file in an external file, mirroring the Zope path/hierarchy. This will allow easy integration with servers that can mount the external representation of the content and serve it with a consistent namespace. To make life zimple, I tried to move all file manipulation to Zope, including upload/download/copy/cut/paste/delete and permissions. These external files are transaction aware, blah blah.. Working with files 20MB I notices some serious performance/scalability issues and investigated. Here are the results. A diff with my changes against version 2.2.2 is available at http://www.superchannel.org/Playground/large_file_zope2.2.2_200010241.diff Concerns: Zope objects like File require data as a seekable file or as a coherent block, rather than as a stream. Initializing/updating these objects *may* require loading the entire file into memory. In memory buffering of request or response data could cause excessive swapping of the working set. Multi-service architecture (ZServer-ZPublisher) could limit the reuse of stream handles. Creating temporary files as FIFOs buffers between the services causes signficant swapping. Modifications: Using pipes I found that FTPServer.ContentCollector was using a StringIO to buffer the uploads from FTP clients. I changed this into a TemporaryFile for a while which revealed the leaked file descriptor bug (see below). This intermediary temp file caused 1 extra file copy for each request. The goal is to not have any intermediary files at all, and pipeline the content directly into the Zope objects. To remove this FTP upload file buffer, I converted the FTP collector again from a TemporaryFile into a pipe with a reader and writer file objects. The FTPRequest receives the reader from which it can process the input on the publish thread in processInputs. Since we are dealing with blocking pipes it is OK to have a reader on the publish thread and a writer on the ZServer thread. The major considerations were regarding the proper way to read from a pipe through the chain of control, especially in cgi.FieldStorage. Stdin is treated as the reader of the pipe throughout the code. All seek()s and tell()s on sys.stdin type objects (a tty not a seekable file) should be considered illegal and removed. Usage of FieldStorage from FTP (Unknown content-length) To gain access to the body of a request, one typically calls REQUEST['BODY'] or REQUEST['BODYFILE']. This returns the file object the FieldStorage copied from stdin. To prevent FieldStorage from copying the file from stdin to a temporary file, we can set the CONTENT_LENGTH header to '0' in the FTP _get_env for a STOR. In this case, FieldStorage creates a temporary file but doesn't read any data from stdin so we can return stdin directly when BODYFILE is requested and 'content-length' is '0'. However, BODYFILE could be a pipe which doesn't support 'seek' or 'tell'. The code used to suck the data off the BODYFILE needs to be modified to adapt to the possibly of being passed a pipe. Updating Image.File to play with pipes The _read_data method of Image.File pulls the data out of the BODYFILE and sticks it in the instance as a string, pdata object, or a linked list of pdata objects. The existing code reads and builds the list in one clean sweep back-to-front. I belive this keeps the pdata.data chunks out of memory, quickly (sub)committing then deactivating (_p_changed = None) them. Since we can no longer safely assume 'seek' is valid for BODYFILE, I tried to read and build the list front-to-back. This kept the data in memory, even though I tried to deactivate the objects quickly. As a tradeoff, I read the data front-to-back then built the list back-to-front taking another pass to reverse the list so it is in the correct order. Memory usage appears to be steady, meaning the whole file is not loaded into the working set. This also prevents unecessary reading into a temporary FieldStorage file during an FTP upload. Web based uploads... ...suck. I do not recommend doing a web based upload for files 1mb. First, a content-length is known, so we don't get the advantage of pipelining the data directly from the socket, a temporary file must be created, written and read. Second, I

Is it faster to modify my installation to allow 2GB or create from xml/export? you could create the python product instances in a mounted db. I looked into this. The webpage is very exclamitory about it's volitility, and yet Zope.org uses it. Worth a shot. do make a backup, i hosed something in my zodb using it. kapil Jason Spisak ___ 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 )

Yes. After adding your LoginManager instance, you
should add four
methods of some sort within the UserSource object.
The four methods are:
userAuthenticate
userExists
userRoles
userDomains
Here's the External methods I used just to make the
logins work; you'll
have to implement them to fit your system:
def userAuthenticate(self, REQUEST, username,
password):
if username == 'morten' and password ==
'morten':
return 1
else:
return 0
def userExists(self, REQUEST, username):
return 1
def userRoles(self, REQUEST, username):
return 'Manager', 'Owner'
def userDomains(self, REQUEST, username):
return []
Hmmm, I tried implementing these functions before,
but only as DTML methods:
userAuthenticate
dtml-return "_.int('1')"
userDomains
dtml-return "['']"
userExists
dtml-return "_.int('1')"
userRoles
dtml-return "['Manager']"
Yet this never seemed to work. Does it not
work because they are DTMLMethods and not External
Methods, or because I am returning the wrong
values, or because of a proxy or security setting?
The Methods are in the User Sources 'folder' and
I am sure I chose "GUF" authentication from the
list when I added the LoginManager.

[Zope] How should a collection be in a Python product if i want to traverse it with dtml-inrse it with dtml-in
This is a question I guess has something to do with popping an object onto
the namespace, or about me not understanding how stuff works.
When I make a list of objects:
class simple:
def __init__(self, value):
self.value = value
theList = [simple(1), simple(2), simple(3), simple(4)]
I would expect to be able to traverse it like below (The objects namespace
would be popped onto the namespace.):
dtml-in theList
dtml-var value
/dtml-in
But it isn't so. What do I need to do to make the objects namespace count in
my traversal? (I'd like to keep the dtml as simple as possible.)
--
If I make a list:
theList = [1, 2, 3, 4]
I can traverse it with:
dtml-in theList
dtml-var sequence-item
/dtml in
-
and if it's a list if dicts:
theList = [{'value':1},{'value':2},{'value':3},{'value':4}]
I can traverse it like:
dtml in theList
dtml-let item=sequence-item
dtml-var "item['value']"

RE: [Zope] Re: [Zope-dev] Task, Job or Operation?
Unsafe has also been proposed. I do not like this either because it is not accurate. Simply because something dangerous, foolish or stupid can be done using this method type does not mean it will be. Are we to label all objects "unsafe" simply because of the capacity of harm? Safety is in the hands of the programer. I agree with this vehemently :) Would you want to use "unsafe C++" or "unsafe Java"? I think "restricted" and "unrestricted" are clear and concise. This is not about "safety" per se, but about capabilities.

[Zope] Is there a tool for pretty-formatting/indenting DTML code?
I've been working with Zope for a bit now and I love it. However, a few of the tools I'm used to having with other scripting tools are missing in the Zope realm.. One thing I would very much like to have is a script that could go through a long DTML document and pretty-format the code, not unlike the way I use BBEdit's formatting command on my Mac for HTML. Does such an animal exist, on any platform, or should I just try to adapt something I already have? I don't want to have to reinvent the wheel so to speak.. The big reason I need this is for indenting.. It makes the code much more readable and I have found myself spending a lot of time doing this by hand.. it just gets tedious.. Thank you..

RE: [Zope] OT:NT and rebooting
From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of It's FUD. I'M running Zope on two NT servers here, which run many months between reboots. I just checked - the Zope on the intranet server has an uptime of 34 days 8 hours 32 min 3 sec now. I must say that I agree. All in all for my current needs, NT is a better choice than Linux. Better user interface and reasonable software uptime. I am slowly migrating to Linux though. As I really do believe the open source philosophy is better. But like Zope it is a b of a learning curve. Something like Zope shows it in a smaller scale. I would be willing to start a business on Zope technology because coorporation on the toolset is the smartest thing for service companies to do, and this is not a closed source option. I have tried some of the closed source application servers and they are so poor. Funnily enough I see companies reinventing the weel with these application servers, doing a lousy job every time. Zope is still not great, but lightyears ahead of anything else I have experienced. Being a web house and not doing an open source app server is so futile.

[Zope] [Fwd: [Zope] Not grocking RESQUEST.set syntax]
Try:

dtml-call some_other_thing_that_uses_filename

This assumes that MyFavoiteZSQLMethod returns the variable filename

thats because you're working on the results returned by a zsql method
which is a result object, you want access to values within it.
try
dtml-call "REQUEST.set('filenames',
MyFavoriteZSQLMethod(REQUEST).dictionaries())"
this returns the list of dictionaries that represent rows in the table,
with column names as keys and column values as values.
you can reference
lib/python/Shared/DC/ZRDB/Results.py
for more info on the results object

[Zope] Filling Multiple Select Problem
Hi!
I'm using the example at the "Filling MULTIPLE SELECT OPTION's with
database lists", and a little step doesn't works.
I heve the following in the DTML Method that fills two SELECT in a Web
Form:
(...)
dtml-call "REQUEST.set('cadExportacao', [])"
dtml-call "REQUEST.set('cadImportacao', [])"
dtml-in sqlVinculacao
dtml-if "tipo=='E'"
dtml-call "cadExportacao.append(codigo)"
dtml-elif "tipo=='I'"
dtml-call "cadImportacao.append(codigo)"
/dtml-if
/dtml-in sqlVinculacao
(...)
The code above runs. To verify that, I put a dtml-var cadExportacao
and a dtml-var cadImportacao, that prints the contents of the lists
above.
The code that is not running is the one bellow:
SELECT NAME="exportadores" MULTIPLE SIZE="10" WIDTH="300"
dtml-in sqlCadastroExportacao
OPTION
VALUE="dtml-var codigo"
dtml-if "codigo in cadExportacao"SELECTED /dtml-if
dtml-var nome
/OPTION
/dtml-in sqlCadastroExportacao
/SELECT
(...)
The code above creates a SELECT list like the one bellow:
SELECT ...
OPTION VALUE="1"NOME 1/OPTION
OPTION VALUE="2"NOME 2/OPTION
OPTION VALUE="3"NOME 3/OPTION
(...)
/SELECT
but the dtml-if "codigo in cadExportacao" part doesn't function. I
have some of the values of "codigo" in the cadExportacao list, but the
"SELECTED" corresponding code doesn't appears.
Can someone tells me what is wrong?
Sorry the bad english...

OK, tim e fo rme to weigh in on this. Reboot frequency is a matter of
experience and perspective. If you are used to uptimes measured in
years, or 'always on' environments, then NT's uptime rates are abject
failures. That's not a slight, it is a statement of fact that even Mr.
Gates himself agrees with and understands.
If, on the other hand, you don't come from that background or need, and
are not used to that type of environment, a few months to six months to
nearly a year can mean something to you.
So, this is *one* of the reasons we see these arguments about uptime
from both sides of the windows vs everything else uptime wars. Some
measure days, some months, and otehrs measure in terms of years.
With three of my
installations of Zope on Linux I have the machines at 194, 204 and 55 days
of uptime (and the 55 was because of a bad powerstrip, the other others have
been up since I brought them up).
So what. I'm using an old 3.51 server on one of my companies

year now (power failure in the machine room, too). That machine
has begun life as a OS/2 Lanmanager server (ca '90), and has
been upgraded almost seamlessly again and again, both in
hardware and in software, since.
And has been rebooted to perfrom those upgrades (software, the hardware
is obvious), has it not?
While NT can and does stay up for long
periods of time, it still is a very poor server choice as anything you
install leads to a reboot.
Well, W2K certainly has more capabilities here, and Linux, for
example, is somewhat better in some (!) areas, but "anything" is
a gross exaggeration.
While I agree that 'anything' is a poor choice of words, unless you are
changing kernels and/or glibc, Linux does not require a reboot for
install of any software (that I am aware of, and that is a high amount
of software mind you). There is work in progress to alleviate that as
well. Not quickly, as it is a rather complex undertaking, but it is
ongoing.
IIRC, kernel 2.4 will/does have support for hot swappable PCI devices on
hardware that has it (yes, you can get Intel-compat hardware with that).
Last I checked, if you try to hot-swap a keyboard or mouse, all versions
minus 2k (haven't tried it there), will die. As far as 'lack of need to
reboot' goes when concerning upgrades, Linux wins hands down..
So, the question regarding uptime is more a question of needs. Some of
us need 24x7 availablility, and 5 nines. Some do not. For those of us
needing 5 nines, we can use Unix/Linux to provide that. If you don't
need it (and not everyone does), use other criteria more appropriate to
your needs.

I think your simplest option is to use:
dtml-call "REQUEST.set('filenale', MyFavouriteZSQLMethod(_.None, _) )"
All that _.Non, _ stuff is the namespace etc that Zope normally passes to
your methods. (I don't fully understand it, I just know it works :)

[Zope] Folder-specific metatypes?
I'm working on a product in Python which implements a folder, but restricts the metatypes of the objects which can be added. How, exactly, do I go about doing this?
