It's due to a combination of the trojan horse issue and the sticky
authentication issue, I think.  You really don't want to be authenticated as
super very often, because while you are, if you visit a page someone else
wrote, they can make your browser do evil things to your site.  This is also
true of Managers, but less so.  Similarly, a page owned by non-super has
tighter permissions than one owned by the super would.

Ideally, people working in a site should be operating with the bare minimum
of privileges to get the job done.  The super should only be called in when
no one else can fix it.

Cheers,

Evan @ digicool & 4-am

Re: [Zope] supplemental group ids (Linux)

I can try...

Supplemental gids are useful for allowing a user to belong to more
than one group, or maybe to more than one project in normal parlance.
This is normally effected by listing the uid opposite more than one
group in /etc/group.  The login process issues the initgroups(3) call
to install these supplemental groups, which are inherited by all
processes forked from the login shell.

The problem is comes when you change user ids; for example what I
saw with Zope (start -u nobody) was:

 before change   after change
 =   
 user id root   nobody
 group idroot   nobody
 sup id(s)   root   root

Thus the process has group access privilages for nobody (correct) and
root (bad) in unpatched Zope.

I cannot give you an exploit based on this -- my knowledge of Zope
is not deep enough -- and in a bug free world there probably would
be no exploit.  But the reason for running as nobody, I think, is
to contain damage should an exploit be found.  For that reason, it
would seem reasonable to change the supplemental gids too.

I saw this on Linux; supplemental groups come from the BSD tradition,
so you likely will find the same situation on *BSD, Solaris, etc.

Chris may have pointed you in the right direction, but depending on
the complexity of what you are doing you may also need to learn about
using proxy roles.  This allows you to write a dtml-method that
an anonymous user can call, where the dtml-method can accessed
privileged functions.  Since you control the method code, you
thereby control the security of that access and can limit it
to just what you need to make the site functional.

[Zope] Managed Meeting semi-broken in 2.2.1

[Bill Anderson]

It appears that there has been _some_ change in security somewhere. As Manager, I 
cannot add a Managed Meeting object in
a Zope 2.2.1 server.
Nor can someone with the role 'Member', who has been given the neccessary permission. 
It tells me I don't have
uthroization to access 'ManagedMeeting'.

[Zope] Arrrgh!!! *Weird* SQLSession problem

[Charlie Wilkinson]

Ok, all weekend I've been chasing my tail.  Now I scream for help...

I cannot get SQLSession to insert values into the zsession_data table
to save my freeking life.  I'm not getting errors of any kind, just no
inserted session data.  However, the zsessions table shows the sessions
being created, so that table is working ok.  I mangled the SQL syntax for
sqlSetValue, *then* I got a pg. error, so sqlSetValue *is* running, yes?
I installed Logger and logged the values from sqlSetValue to the zope log.
I cut and pasted those values from the log into the test query screen for
sqlSetValues and when I submit the query it inserts just fine.  At that
point I can see the manually inserted values from session_test.dtml, so
sqlGetValues is working.  But if I try to insert values with session_test,
they show up in the very next screen, but are gone thereafter and of
course they do not show up in the database.  I'm really at quite a loss here.

I made sure to give SQLSession its very own ZPyGresQLDA connection.
After beating on that unsuccessfully for awhile, I installed ZPoPyDA,
and set SQLSession to use that, which of course didn't change anything.

Here's the version particulars:

Zope version: Zope 2.1.6 (source release, python 1.5.2, linux2) 
Python version: 1.5.2 (#1, Sep 17 1999, 20:15:36) [GCC egcs-2.91.66 19990314/Linux 
(egcs- 
System Platform: linux-i386 

ZPyGreSQLDA 0.3
ZPoPyDA 0.5.1
PoPy 1.3.2 beta
SQLSession 0.3.0
PostgreSQL 7.0.2

Other installed products (if it matters...):

ZPyGreSQLDA Fortune Calendar Logger Photo ZPatterns Confera LoginManager
SQLSession ZPoPyDA WorldPilot iTrack

Mild rant:

I've got a big, scary, and now behind schedule database-enabled website
to build for a client.  Most everything I've read, and even my earlier,
simpler experiences with Zope have been fantastic.  I've been going
on to my client about how great Zope is, rapid deployment, etc, blah.
So I committed, but after fighting with LM (It took weeks to get it
working once and I have not been able to duplicate that feat since), a
failed upgrade to Zope 2.2 (LM wouldn't work there yet(?), doh!), and now
SQLSession...  I'm *not* having an overall good feeling about all this.
I'm even starting to get thoughts of retreating to Perl or learning PHP3
and never looking back.  But I really want to get over what's probably
mostly newbie learning curve & lack of docs and make this work in Zope.
Please help!!!

[Zope] Java applet with inner classes causing probs in Zope

Hello all,

The problem is that inner classes have names like "Parent$Inner.class"
I'm unable to create a Zope file object with a name that includes the dollar
sign.  However, the applet won't function without it.

Has any one overcome this?

Yes, the applet functions properly when served from apache (but I need to
serve it from Zope).

Please respond directly to me and mailing list as I am not currently on the

[Zope] Stumped: Python in operator seems to not work

[Andy Dustman]

(Please CC: me on responses.)

I have a DTML Method (build_navigation_bar) that is called from
standard_html_header to (surprise) build a navigation
bar. standard_html_header invokes it thusly:



where foo is the top of the tree; standard_html_header can be acquired
further down in the tree. parents is initialized to PARENTS, which is the
list of parents of the original object. build_navigation_bar invokes
itself on Folders that it finds that are among the parents of the original
object. I.e., this is somewhat like a tree, but we only want to expand the
branch we're in. This is done with:




  
  
  


  




Unfortunately, this doesn't work: The conditional is always false. Some of
the debugging output:




Note that in the first line, the expression correctly evaluates to 0,
while the second line incorrectly evaluates to 0. Using  should not, and does not, make a difference. Initializing
parents with a copy of PARENTS (PARENTS[:]) does not make a difference, as
expected. Direct comparisons, i.e.  (or
==) also fail.

What did I overlook, because this seems like it ought to work.

Do you have "acquire permissions" set on all the permissions of the
folder?  Have you tried turning it off?

This may be a wild goose chase because I'm sort of guessing at your
problem.   Your message has generalizations like "that one subfolder"
(what subfolder?  what are its settings?), "set all the security"
(how?), "does not do what I want" (what do you want?  exactly how
does it fail, can you give a concrete example?) and "the page" (what
page?).  It'd be helpful to define these, because as much as I try, I
can't read minds.  :-)

[Zope] newbie question: installing ZSiteMap and ZPhotoAlbum

[Tamara Temple]

Hi all,

My first posting here, please forgive if this is obvious, cause it
isn't to me. I already checked the How-To's and searched the zope-list
archives and came up with nothing.

I downloaded the two zexp files for ZSiteMap and ZPhotoAlbum, and put
them in the import directory. When I try to import them, I get an
error and a traceback saying that "this operation isn't support by
ZSiteMap" (or ZPhotoAlbum, depending). There are no instructions with
either one on how to install them. What do I need to do in order for
these to work?

This newbie thanks you in advance.

Re: [Zope] Fourth Posting, is this really that difficult or have Ibeen blackballed :)balled :)

[Chris McDonough]

One thing to remember about using __init__ to add subobjects:  during
__init__, you don't have access to any acquired objects.  This is probably
the main rationale for manage_afterAdd, and is the reason manage_afterAdd
is so useful.  There are a lot of dependencies on acquisition even in the
Zope core, so when things fail during your __init__ method, suspect
acquisition dependence.

Won't work, the container will still be parsed for correctness at 'save' time.
The problem isn't getting nested comments per se, we already have that. 
The problem is to completely ignore the contents of the comment tag whilst
still allowing nested comments.

Th second part of the problem is that ChrisW(hinger) really wants it, but,
doesn't want to do what is necessary to do it. So the problem is simplified
to not actually doing anything except talking about doing it. d8)

OK, I think that I am perhaps misusing zclasses then.  Here is what I
have.

I have a Folder that was created by using the 'Add new item' menu
within Zope.  This folder is called 'Site'.

I have a Zclass called 'theatre_class' that has "Base classes ZObject,
_ZClass_for_CatalogAware, _ZClass_for_DTMLDocument".  I have set the
zclass to have the following properties by creating a
'theatre_class_property' property sheet for it:
head_title
meta_author
meta_description
... amongst others.

Within the Folder 'Site', I have standard_html_header dtml-method that
is an edited version of the default one that is found in the root
folder of a Zope instance (if that is the right term).  This
standard_html_header uses things code such as this:




When I use the standard_html_header in an instance of a zclass, the
appropriate property of the zclass is indeed inserted into it.  See
below.

Zclass instance has code such as:



This is an instance of my Theatre Zclass



However, if I try to put  into the standard_html_header,
I get nothing, and if I use , I get
'standard_html_header' inserted into the document.

I hope I have made it clear what I am doing.  It is certainly becoming
clear to me that I have got the wrong end of the stick a little with
this.

Thanks for your help.

[Zope] supplemental group ids (Linux)

[Kip Rugger]

I noticed when starting Zope as root (to get privilaged ports),
but requesting suid to `nobody' (start -u nobody) the resulting
processes have the correct uid and gid, but the supplemental
group id list still has the appropriate value for root.  This
means that the Zope process could, for example, write to files
that may belong to root.

It's not clear whether this deserves a bug report, so I though
I'd ask here instead.


The fix is easy (and very lightly tested):

1) grab and install the supplemental gid package (for python)
   http://www.ccraig.org/software/group.c

2) patch (for 2.2.0)

I've got to say I agree with you here.  I'm still not 100% sure why the
superuser or bootstrap user can't own anything.  The argument for
protecting the user against himself by making this so is something I had a
rough time rationalizing in that document.  I suppose there's the argument
for having a meaningful audit trail when things go wrong (instead of
superuser hosing your site, it'd be "chrism").  But this is also a
rationalization.  I guess the ultimate answer is "shrug."

I'm certainly not even going to think of trying to tear apart the code
that makes it that way (nevermind the flamefest it would cause). Rather,
to ameliorate the situation, Zope should prompt the installer to define a
separate management user at setup.

No.  But the document is divided into sections, and one of those sections

No traceback, because no exception.

I speak of a true rounding problem:

the image is modified at "x" (expressed in seconds)
Zope sends "x" converted to a date/time string as "Last-Modified"
Zope receives the date/time string back as "If-Modified-Since".
Zope converts it to a "long", say y.

*BUT* y is not x, it is "x-1".

Of cause, this does not happen for all modification times. But there
are not too few of them.

I, myself, have seen a very similar problem -- with Netscape 4.5.1
under Solaris 2.7.

I tried to analyse it, but failed.
I can say, that is was *not* the Netscape image bug
(Netscape sends If-Modified-Since headers with two year digits). 
Inside Zope's "OFS.Image.File.index_html" everything looks fine.

When I do this, I get the id of the Z class instance.
It should be impossible to get the id of the *standard_html_header*,
if this header is a DTML *method* (rather than document) as you
told us in a different message.

Because we see different things, we need to describe carefully,
what we do. Apparently, we do not do the same.

I have a folder-like ZClass, say ZC, and an instance of this class, say ZI.
ZC has a method, say M, using "standard_html_header".
"standard_html_header" is a DMTL method (!) rendering "id".
When I open "ZI/M", "standard_html_header" renders "ZI", i.e.
ZI's id.

The same happens, if "standard_html_header" is not in ZI but
a ZC method.


Now, it is your turn to describe precisely, what you are doing.

There is a GUF (Generic User Folder) HowTo that explains
how to use encryted passwords in the same way as you do.

After you have set up GUF (very good explanation in the HowTo),
all you need to do is place your "username,password" pairs
into the database.
A small Python script can be used for this. It probably would
use the DB Api to control the database.

Re: [Zope] Way to list vocabulary words specific to a page?

[Dieter Maurer]

Kevin Smith writes:

Zope does not manage vocabulary words on a page basis.
Therefore, you cannot simply ask: "give me the words for this given
page".

With some effort, you can emulate ZCatalogs word splitting:

  given an object, "o", and an attribute, "a", to be indexed,
  ZCatalog first determines "o"s "a" value:

val= getattr(o,a)
if callable(val): val= val()

  The resulting string is then fed to a C implemented module
  called "Splitter" which splits the text into a sequence
  of words.

  It is this sequence, you are interested in.


You will probably need to write an external method.
You will find the relevant code in "SearchIndex.UnTextIndex".

asp+ (the next version of asp) will be following Zope's lead of template style setups, 
seperating code from content. I
don't have the release handy, but I saw it last week or so.

[Zope] domains (acl_users) and access via proxy

[Didier Georgieff]

Hello,

Our users are acessing to the Zope server thru corporate 
(ministers) proxys.

I can't get the "domains" working, while trying (agriculture.gouv.fr, 
gouv.fr, fr) even with simple one.
I'm suspecting some changes in the REQUEST made by the 
corporate proxys.

Is there any doc about what REQUEST variable is used in the 
"domains" restriction ? (I have a HTTP_FORWARDED with the 
*proxy* name (unfortunately without the .gouv.fr). I can't find 
anything on the site and the list either.

Thanks in advance.

Re: [Zope] Non-blocking MailHost

[Loren Stafford]

One way to start an asynchronous job in Zope is with the Xron product.
Instead of sending the email, you create a Xron scheduled method to perform
that task. If you specify a trigger time of "now" (or any time in the past),
the scheduled method will execute (almost) immediately in a separate Zope
thread. Or you could specify a later time for all emails, thereby
effectively batching them. You can store as much context as you need in the
acquisition path or properties of  the scheduled method. Anything written to
STDOUT by the scheduled method will be stored in the log file, so you can
easily log any problems with sendmail.

It is easy to implement a Python wrapper for the

Re: [Zope] Catalog AND Zieve

[Steve Spicklemire]

Hi Jean-Francios,

You need to give Zieve a list of objects that have the attributes that
you want to sort on defined. You can ether build a list of 'real
results' from the ZCatalog that can then be passed to your Zieve, or
you can just make sure the ZCatalog's 'meta_data_table' has all the
attributes you might want to sort on. I haven't been following all the
changes, but I think that the newer '' may now support
dynamic sorting... I'm sure I saw some patches about this... I don't
know off hand if they've been incorporated into Zope-2.2.1, but I'll
check...

Re: [Zope] Non-blocking MailHost

[Richard Taylor]

I think what people have in mind (correct me if I am wrong) is
something that will accept messages (for posting to the mailhost at
some time in the future) and then immediately return. I guess it would spawn
another process/thread to do the posting asynchronously.

The problem, as I see it is how to handle an error with the
posting. The user who submitted the mail is now long gone so it must
be left to an administrator to pick up the pieces.

Perhaps the posting routine could accept a user (developer) provided
exception handler that gets called if a posting fails.

It maybe better to just hand this off to a completely separate program
rather than try to handle it within a zope thread.

Re: [Zope] doesn't? Please fix... ;-)

[Doug Hellmann]

I missed the beginning of this thread, so I'm not sure if this will
help.

I've attached a patch file which will add a DTML-commentline tag.  This
is different from the standard DTML-comment in that it does not require
an end tag.  Here's an example of its use:







This segment prints the 'title_or_id' for the current method, and does
not execute the loop.  Obviously the DTML-in syntax isn't correct, but
that's part of how the commentline tag works.  It eats up everything in
its own <> markers, and allows the DTML parser to ignore it.  It *does
not* go all the way to the end of the input line, as the name might
imply.

[neeloy_saha]

Hi all,

I am getting the following error when i try to install the portal toolkit
with the ' experimental login manager support'.
I am using the zpatterns version : ZPatterns-0-4-1snap1and demo portal :
0.8.2 and other products. If I create the portal with no initail member then
i am able to have a portal with login manager support. But then after I have
installed the portal I am unable to add a member. ??

Can i have a working snapshot of the portal toolkit with the login manager
for  a windows version or probably a direction as to how to go abt fixing
the above problem??

Re: [Zope] Images slow rendering problem

[andres]

What IE browser are you using? What version of Zope? A similar sort of problem
was once traced to a Y2K problem with IE but the new versions of Zope
(>2.1.6) should be able to handle the problem gracefully now.

Can you try Zope 2.2?
 
Also, I posted a few times about this recently, there are some patches
mentioned in there which you could try, although if they help, I'd be a
bit worried about the processing of the 'if-modified-since' header that
Zope is doing :-(

Anyway, let us know if either of the above helps,

Hi,

I've got the problem with Zope 2.1.6 on a FreeBSD box.
In fact, IE AND NS are affected (all versions, 3, 4, 5...), while NS
less frequently than IE (???).

In order to parse that fragment, you need to parse the blocks in case you

Now you know the problem domain, it shouldn't be hard for you to create

You misunderstand how Zoep sucks ;-)

The problem is making the mirror. I've seen quite a few postings
describing how the common mirroring tools don't do a very good job of
mirroring Zope sites, because of things like that BASE tag abomination
and the confusion about what objects a file-system like 'folders' and
what objects aren't.

Anyone knwo of a tool that _does_ mirror Zope well?

That said, if that patch stops this happening for these browsers, then I
think Zope has a problem that needs fixing.
Can you try Zope 2.2.1 in the same situation and see if you still get
the same problems?

I'd guess something ZSQL-related is the problem. IMHO, Zope's working
with SQL are/were significantly less reliable than any other part of
Zope. I'm just hoping someone wil tell me I'm talkign crap, and back it
up with evidence ;-)

This does seem a lot like the "If-Modified-Since problem" in 2.1.6
caused by certain versions of Netscape sending crap header information
back to Zope, and zope throwing an exception.

IIRC, 2.2 handles this much better...

Check these bugs and see if any help:
http://classic.zope.org:8080/Collector/1014/view
http://classic.zope.org:8080/Collector/1388/view

And try it with 2.2 to see if it's still broken...

Well, okay, let me rephrase the question:
Why is it bad for the bootstrap user to own anything?
It used to be considered okay before Zope 2.2, so was has been
changed/discovered that makes this now such a bad idea that despite
loads of newbie pain and confusion, it's still worth while/necessary?

Urm, again, no offence ('cos I think the book is aimed at a different
audience) but the keyword for me was 'concise'. I did have a look at the
document above, but didn't read it 'cos it looked about 10 pages long
:-(

I'm looking for something closer to 10 _lines_ long, but that may not be
possible ;-)

AFAIK, Brian Lloyd fixed this with a pretty generalised try...except in
Image.py
If stuff is still getting through, we should narrow it down further...

A traceback for this would go a long way

> Anyone know how or want to write one?

first, lets gather some requirements...

probably best done on a fishbowl wikis... any volunteers?:)

what do you mean by non-blocking MailHost, the smtplib.py waits for a
reply to see if it should raise an error, but thats it as far as block
that i see, i pretty much regard that as nonblocking and proper. if
you're looking for send which doesn't check for reply than you could
just hack smtplib but i doubt you'd see any performance benefit.

assuming that smtplib and Mailhost are nonblocking... then the question
becomes how to make it suitable for bulk emails and what are the
requirements?

do you want a mailhost that isn't connected to via a publishing thread?
ie is it a requirement that processing won't affect a zope site and no
response will be sent back to zope for messages processed (although an
xml-rpc callback is possible).

do you want to get respones back for messages you've sent?

if this going to be added as a general zope feature its probably best to
add some sort of mail queue, that can be added to by other zope objects.
this would also avoid the overhead of connecting to the mailserver on
every mail send.

does it need to be multi=platform? (ie no cron, no popen2) if its for
squishdot i guess i can assume the answer to this and my next question
are yes.

are zope/python solutions preferred? i ask because i've been considering
a zope bridge into JServ which has an enterprise capable email system in
James (http://java.apache.org/james/)

a quick stab at portable implementation outside of zope would bundle a
python script to be called by popen2 on Unix or spawnv on Windows that
would read a pickle of email data and send it. course its ugly but it
would work, could even get fancy and do it with an asyncore.

another quick stab, if you assume the existence of xron, you could store
email messages to be sent and a list of addrs to which they should be
sent and xron it to be sent some other time. 

one possible (minor) speed improvement depending on the protocol def and
the various server implementation is to mantain an open socket to the
server as part of the MailHost, or at least maintain for as long as
possible before getting a new connection.

i need to sleep, i'll brainstorm some more in the morning

night

Kapil

Well, the parsing should be pretty simple:

you might want to grab a copy of the ZQR which goes through most of the

there is also a way to set this to be local time(your zope that is)

you might want to check out some of the howtos on DTML stuff, although
generally its easier to do complex calculations in a python method.

bobobase_modification_time is a method that returns a date time object,
its just formatted as a string on the page when you render it.

Right now I don't have the time to go take a deeper look at this (or isn't
it that deep?), so I tried to DE-install zzLocale, just for now. Well:
Zope(Win2k :-() won't work without it anymore!!!

What I did was remove the product through the product management screen,
then deleting the folder "Locales" in lib/python and the folder "zzLocale"
in lib/python/Products and then restart Zope. Actually just vice versa of
what I did when installing it...

[Zope] Migrating passwords from Apache to Zope?

[Marcin Kasperski]

Is it possible to smoothly migrate accounts and passwords from Apache to
Zope? 

More details: I keep Apache accounts in some file of the format

username:encoded_password

where username is plaintext username and encoded_password is the
password encoded in the normal Unix way (via crypt function). I would
like to migrate those accounts to Zope. I do not know the passwords and
I would not like to ask users for them or force them to change the
password.

Is it possible?

Re: [Zope] PyWinTypes15.dll not found

[tom smith]

I had this problem...and the paths reported are a bit spurious if I remember
rightly.

I think I got complaints about Tk/Tcl, then MTS, then something else. The
dialog that popped up is on a remote server, so I had to fix this quickly.

To fix it. I reinstalled python (Don't know if I needed to do this) and
Tcl/TK (part of the same installer). I don't think you need to do this.

Then I copied and pasted the PyWinTypes.dll. Tk80.dll. (Maybe the Msvcrt.dll
too) into to the Zope/lib/Python/ folder. If they're already there, copy
them into your python DLL folder. OK, I admit it, I sprayed them all over
the place, restarted and I've not had any bother since.

This problem *may* be caused by the Tcl install, making a mess of the
registry. I don't think you need Tcl for zope, so next time I won't install
it and see if the same problem happens

hope this helps

tom

What we really want is a non-blocking MailHost.

Anyone know how or want to write one?

[Zope] Zope + Apache + fastcgi + unix socket ..

[Jørgen Skogstad]

Hi there.. 

Have any1 of you gotten local unix domain socket style access
of Zope behind Apache to work? I have not .. and I am running
this on Solaris. 

I see that Apache is trying to access the "file" .. and I presume
the request is passed to fastcgi .. but I never see the request 
in Z2.log.

I have fired Zope with socket access .. and configured Fast-
CgiExternalServer .. etc. for apache.

Anyone have any information about this? Would apriciate any!
I have browsed www.zope.org too .. without any success .. ;)

[Zope] Images slow rendering problem

[Pierre-Julien Grizel]

Hi,

I already posted this message several monthes ago, expecting a new Zope
version would fix the problem, but...


I have some images on my pages (let's say 10 - not a lot), rendered
either by dtml-var or a manual  tag.
When I render the page on some of my LAN boxes (especially with IE),
some images doesn't load at the first time. I need to reload the page to
make them appear. When I monkeyly hit the 'F5' key, some images do not
show again. Argl. Anoying

The problem is worst ever through Internet.




Any clues ? Is it a Zope images rendering problem ?



Many thanks,

P.-J.

Re: [Zope] Re: File Attachments with Sendmail

[Brendon Grunewald]

Dear Luis,

Dieter Mauer was kind enough to assist me with the answer to this question.
The normal Sendmail tag does not accept variables.

You need to install the MIME.py.patch. Once that is done you can include
variables.

Re: [Zope] PyWinTypes15.dll not found

[Philipp Auersperg]

This dll exists in  in the Zope tree in the directories bin and bin\lib\win32.
unfortunately none of these is in the PYTHONPATH.

Remedy:

copy PyWinTypes15.dll into one of the directories where it
searches for ( e.g. in your case C:\programs\ZopeDev\lib\python\Products\LocalFS)

or

change the start.bat so that PythonPath also points to these directories

[Zope] Help with calcualtions in DTML

[Dario Lopez-Kästen]

Hello!

I have the following listing of objects in my folder:


  
Name
Size
date
  

  

  


   bytes


  

  



It gives me the name of the object, the size in bytes and the modification
time in GMT.

I need to do the following: express the size in kb, format the output with
spaces for thousands.

I also need the date displayed according to my locale (+2 GMT in Sweden) so
if bobobase_modification_time is 10:48, I need to show it as 8:48, and on
top of that I also need to take dayligth savings into account.

How do I do it? The fmt strings are abviously adjusted to US standards, so
us ISO-people need to hack our own format strings :-).

I know i could calculate the size in KB myself IF I only knew how to get the
get_size attribute into a calculation expression (that goes for
bobobase_modification_time as well, however this returns as string. How do I
get the date as a date?)

Any help is appreciated and needed. Thank you.

/dario

PS: has anyone been thinking of renaming bobobase_modification_time to
something shorter and more intuitive, like, say, modification_time?

:-))

[Zope] The difference between ControlSet 001 and 002 ..

[Jean Jordaan]

Answering myself, from the Resource Pro Kit:

..
The  subkeys represent a control set for the system.

The numbered ControlSet00n subkeys, such as ControlSet001 and ControlSet002,
contain control sets that can be used to start and run Windows 2000. Most
systems have two numbered control sets, an original and a backup copy of a
control set that has been used to start the system successfully, but the
system can maintain as many as four control sets. Windows 2000 maintains
backup copies so that you can undo configuration changes that might
otherwise prevent you from starting the system.
..

So that's that, anyway. For the record, the current one in my case
was number 1.

[Zope] PyWinTypes15.dll not found

[Jean Jordaan]

Hi Zopers ..

I've installed Zope to start as a service. It seems to work perfectly
fine, but I notice messages like the following in the eventlog::

2000/09/02  10:25:36Application Popup   Information None

(I broke the path into separate lines for clarity.) Now, when I
examine the environment variables thru 
'Control Panel|System|Advanced|Environment Variables', Zope does not
feature. I also don't notice anything untoward when I examine the
registry. The registry entry that starts Zope seems to be::

REGEDIT4

00,01,01,00,00,00,00,00,05,12,00,00,00

(This also occurs as
[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\ZopeDev]
except that the 'ControlSet001' version has an additional key, 'Enum'::

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\ZopeDev\Enum]
"0"="Root\\LEGACY_ZOPEDEV\\"
"Count"=dword:0001
"NextInstance"=dword:0001

Now for the questions:

 - What is the difference between the 'ControlSet002' version and the
   'ControlSet001' version? 

 - How and where does 'LocalFS' get into the path? 

 - Why isn't 'C:\programs\ZopeDev\bin\lib\win32\PyWinTypes15.dll'
   found? 

 - What, for that matter, is the difference between *that*
   PyWinTypes15 and this one:
   'C:\programs\ZopeDev\bin\PyWinTypes15.dll'?

Any answers sorely appreciated!
