Re: [Zope] multiple ZOPE ...

[Simon Coles]

>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.

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

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] Download Problems & File Extensions

I've seen this happen due to a couple of things:

1. An archive not being completely downloaded (check the file size in
Bytes matches that listed on the download site)

2. Windoze giving the downloaded file the wrong extension. This can get
particularly tricky when Windoze plays it's game of hiding file
extensions it thinks it knows about. Check the whole file extension
matches that from the download site (usually .tar.gz)

cheers,

Chris

that's where the problem is: in your REQUEST there _are_ no Field1 and
Field2: they are in the testlist (pseudo) dictionary.




Make you method (something like):


 INSERT INTO Test_Fields
 (Field1,Field2)
 VALUES
 (
 ,
 
 )

I think so (terminology is a bit confusing here). ZSQL methods only take
named arguments. There has been quite a bit of threads on this on the
list. SO you might want to search the archives for them.

In this case the named argument would have to be testlist, as this is
the argument REQUEST contains.

WorldPilot's Palm side of things was still broken last I checked (last week,

through other means. Get the freshest version of the software you can as it
might be fixed now.

[Zope] Help needed with namespace

[a . wacknitz]

Hello all,

after updating to Zope-2.2.0 I have problems with ZSQL methods.
It seems as if the namespace of ZSQL methods has changed sind Zope-2.1.x.
I cannot access the AUTHENTICATED_USER object anymore - it is not known to
ZSQL methods:

gives an "Missing input variable, AUTHENTICATED_USER" error
and

gives "error type:  NameError
   error value: AUTHENTICATED_USER"

The security mechanism of my application heavily depends on this object!
What has happened to the ZSQL methods? I have already updated to Zope-2.2.2
but with no luck so far.

Any help is greatly appreciated,
Andreas

[Zope] Newbie-question on ZCatalog

[Marc Breitenreicher]

Hi,

I'm trying to build a Catalog with a report table just as the one on
http://classic.zope.org:8080/Collector/tableBrowse?cfDescAndTitle=catalog

That's a table with document-title, date and the first 30 words of the
document-content.

My problem: how can I insert the content into the ZSearch report-file?
Is there a simple way just like finding out the document-url 
( here it is  )?

Thanks for your help

Re: [Zope] RedHat site mentions Zope (SuSE too!)

[Joachim Werner]

I checked:

Zope 2.1.6 is shipped with the DeLuxe and Server versions of RedHat 7.0, but
not with the Standard edition. They have split Zope into a couple of separate
packages. On the web page they mention Zope a couple of times!

BTW:

Zope (also the 2.1.6) is also on the SuSE 7.0 (Professional) distribution. So
Zope is now on most of the major distributions (RedHat, SuSE, Debian)!

[Zope] ZClass + ZSQLmethods bug in 2.2.2?

[Alexander Schonfeld]

Hi,

I've seen lots of ZSQLmethods patches and such and tried a few of them
under 2.1.6, but thought upgrading to 2.2.2 would fix this problem.  It
didn't.

Basically:
1. Create a ZClass
2. Inside create a DTML method and ZSQLmethod
3. from the dtml method call the ZSQLmethod
4. do a  

5. get a Unauthorized error no matter what the access privileges
are set to

This is with the "MySQLda".  Is there a newer MySQLda somewhere that
fixes this?  Or some patch (that works with 2.2.2???)?!

Running 2.2.2 from source... now with less hair...
Sincerely,

Alex.

[Zope] 1000-record limit?

[Christopher J. Kucera]

Greetings!

I know I saw this discussed a long time ago, but I completely failed
to find the thread anywhere, so here goes . . .

We're running a somewhat older release of Zope with ZOracleDA, and
we've run up against a 1000-record limit when returning data for
reports, etc.  I know that this is intended behavior (careful_range
in DT_Util.py), but I'm wondering what the reasoning is, and if I
should be even considering playing around with this (I'm assuming
it was put in there for *some* reason . . . :)

Thanks in advance for your help!

Take a look at the "Advanced" tab of your SQL methods...

Ok, well, SiteAccess2 is now the only "canonical" version.  The only way
to get to SiteAccess1 is by going to SiteAccess2 and selecting the old

[Zope] ZFormulator -- how to make an SQL insert?

[Mike Renfro]

I looked in the archives for anything concerning this, and came up
empty. I have zformulator set up with postgres, and it appears to work
fine, except that I've not found the zen to make it actually do an SQL
insert -- I know the GetSQL method will extract the proper code, but
am I missing something trivial that'll let me actually execute the SQL
code? Thanks.

[Zope] PyGreSQLDA

[Leichtman, David J]

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? I have a pgsql db running just
fine, and in Zope I have a connection instantiated at the top level that all
of my ZSQL methods use. 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. However, if multiple people try to run a query at
the same time, it usually takes a few seconds, as if only one person were
connected at a time.

I'd love elucidation from someone educated on this subject, as I am most
certainly not :)

[Zope] [Fwd: Zope Question]

[Ryan Booz]

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

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.

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.

   I have 3 connections just fine. Sometimes Zope timeouts a connection,
but when someone touches it, Zope reopens the connection automatically. No

[Zope] Zope Dies with FastCGI

[Ronald L. Roeber]

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  (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. I am starting the Zope server with the -Z option. 

Ideas. I'm about ready to start making the server more widely available
but cannot if
the server is unreliable.

Ideas, strategies, options? 

TIA

Hm, I've been sadly neglecting ZFormulator for a long time. I will
have some time to work with it again next month, though.

I'm surprised it actually works with Zope 2.2; I had some bug reports.

You cannot do an actual SQL insert with ZFormulator yet, though it
wouldn't be too hard to put some code around it to do. Right now
ZFormulator only shows the SQL statement. I believe I had some patches
contributed that do enable this, which I've been neglecting as well. :(

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).

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?

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.

Hello, Zopers.

Try this:

Create a DTML Method in Zope. Give it an id of 'target', and give it the
following body:

  Woohoo!

Now manage the folder that it is contained in. Instant tab augmentation!

Let's say I'm user Joe and I have a role "Employee" that allows me certain
functions throughout the site.  A role "DepartmentManager" is also
available, but I only have that role where it is given to me as a local
role in the "accounting" folder.

Let's say there's another folder on the site called "hr", for human
resources.  If security were context-dependent rather than
containment-dependent then I could just access

http://www.somesite.com/intranet/accounting/intranet/hr/manage

and I'd have "DepartmentManager" privileges in the "hr" folder.  Oops!  
(Note that there is only one "intranet" folder.  This URL uses acquisition
trickery.)

(More info in my reply to your next message...)

Tell us what kind of security you're trying to set up, and we can probably
help you find the right way to do it.

Out of the box Zope starts up in debug mode. Remove the -D flag from the
start script (aptly named 'start') and you'll be dandy. Run 'python z2.py
-h' for more startup options.

The Apache server can do much more than serving HTML pages form a disk.
Using FastCGI, Apache runs all requests starting with the /zope URL
throuhg FastCGI, which returns not HTML files but the results of the
REQUEST passed through to the Zope server. No file system has a look in on
that process.

In fact, you can run Zope without Apache as well. If you didn't touch the
z2.py startup parameters, then you can point your browser at port 8080 of
you server and see your Zope server there.

Now, do you ask, where does Zope get's it's pages from? You still don't
see a directory... Zope doesn't serve files, but Objects. (You may want to
read up on Object Oriented theory here, there is some good intro material
on Zope.org as well). These objects are stored in a Object Database, the
ZODB. The default storage is in a file called Data.fs, which you'll find
in the var subdirectory. Nuke that file and you have lost all your
objects.

Zope doesn't serve files, at least not out of the box. There is a product
called LocalFS that may help you accomplish this with just Zope.

You can also use Apache with some Rewrite rules to combine the
'namespaces' into one; / is Zope, but /~username is a subdirectory of a
homedirectory. Again, there are several How-To's on Zope.org that will
help you with this.

Hope this helps!

Looking over your mail again, it seems that there is already an AccessRule
registered, but it is of the wrong type. You can't remove it with the Add
interface, because that triggers the error.

Instead, you'll have to do this in your Zope root directory (I am assuming
that the MOnitor client is running at it's default port of 8099):

cat access
# copy everything after the first ':'. This is your monitor password.

python ZServer/medusa/monitor_client.py localhost 8099
# paste the monitor password

import Zope
from Products.SiteAccess.AccessRule import manage_addAccessRule
app=Zope.app()
manage_addAccessRule(app)
get_transaction().commit()

The Access Rule is now cleared.

[Zope] String manipulation

[Spicklemire, Jerry]

"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:




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...

[Ramiro Brito Willmersdorf]

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.

ZPYGre is not threadsafe, so with it and all non-threadsafe da's zope
uses a lock around access. (Thunked.py)

The solution is to just use multiple DA connections and let postgres
sort out the concurrency issues.

I've seen this problem before. ie mangles the file name and winzip
doesn't seem to like .tar.gz extensions (i think?) . just rename it with
.tgz extension and winzip will be happy.

i'm not clear about "use multiple DA connections".  let's say i have several 
sql methods.  it is meant for one particular app.  do i create a few  db 
connections and assign them to different sql methods?

anybody know whether PoPy is threadsafe already?

thanks and sorry to be a bone head :)

[Zope] secure management with Site Access?

[Rob Miller]

Is anyone using the Apache/mod_proxy/SiteAccess method of using Zope with
the ability to access a given virtual host both with and without SSL
encryption?  If so, can you give me some pointers on how to accomplish
this?  I'd like to use SSL for all of my management activity but have the
main site be available for non-encrypted viewing.  The 'SiteRoot', though,
will only rewrite the URLs with either 'http' or 'https', and isn't smart
enough to do one or the other depending on the form of the original
request.

Is what I want to do even possible, or will I have to resort to using some
sort of PCGI solution to accomplish my goal?

thanks,

rob

We also included Zope 2.1.6 is also included in the new Storm Linux 2000
(which is based on Debian). We liked Zope so much, we put it on all of
our editions (Starter, Open, and Deluxe) :)

We also mention Zope on the list of included packages on the outside of
Deluxe box.

And we use Zope to power our web site:

Not only that, they put Zope in at least one of their magazine ads!  :-)

Reading Linux Journal, did a doubletake when I saw the swollen Z.

Pointing a virtual host directly at manage I can do, but where do I put the
SiteRoot?  If I put an https SiteRoot in a directory, then plain ol'
unencrypted access won't be happening... all of the URLs inside the site
will point to 'https://' instead of 'http://', right?  Or am I missing
something?

Again, getting Apache to do the right thing I've got figured out.  It's
just the SiteRoot causing the problem; all of the links inside the folder
with the SiteRoot will be either 'http' or 'https', but I'm looking for
some solution that will allow either, depending on the previous REQUEST.  I
know that SiteRoot is basically a special kind of access rule, maybe a
smarter access rule can be used instead of a SiteRoot...

Thanks for your feedback, and please let me know if there's something that
I'm not seeing.

The CVS version works better.  I have got it to synch memos, todos and
addresses with no problem.  The calendar entries get transferred but when
they appear on the web page the times and dates are awry.

i would factor your sql methods into logical groups and give dedicated
connections to groups which might have signifigant concurrent access.
Giving dedicated connections to every method is not productive as you
just increase concurrency problens on the db side. 

an example might be a dedicated connection for user related info,
sessions, etc. and another for a news system.

> anybody know whether PoPy is threadsafe already?

some reference regarding threadsafety as defined by the python dbi from
the db-sig group.

BEGIN REF
Integer constant stating the level of thread safety the interface
supports. Possible values are: 
  0
= Threads may not share the module.
  1
= Threads may share the module, but not connections.
  2
= Threads may share the module and connections.
  3
= Threads may share the module, connections and cursors.


 Sharing in the above context means that two threads may use a
resource without wrapping it using a mutex semaphore to
 implement resource locking. Note that you cannot always make
external resources thread safe by managing access using a
 mutex: the resource may rely on global variables or other
external sources that are beyond your control. 
END REF

First this is in regards to the underlying python lib that drives the
DA. both PyGre and PoPy are thread safety 1. Words have been said to the
effect that the developers of PoPy would like to raise the thread safety
of PoPy to 2. I'm not sure if D'arcy(author PyGre) has any such plans,
however he is a contributor to Postgres and does maintain PyGre.  PyGre
did not use to conform to the python DBI, since it was written to
support the features of Postgres, there is a now a wrapper around it
provide this abstraction. PoPy was built to support the python DBI. I
bring this info up because the DA for PyGre is dated and does not appear
to be supported, but its important to realize that this DA is just a
thin wrapper around the underlying db access lib, and for Postgres both
of these are being worked on.

if you really want a thread safe DA you're going to have to look towards
the commercial DBs. rumor has it that someone at DC is writing a new
Oracle adaptor.

> thanks and sorry to be a bone head :)

no worries, if people never asked than we would all be learning by trial
and error.
