[Zope] Number of zope processes on Linux and OpenBSD
Howdy! I have a question concerning the number of running zope processes: I used to run Zope under Linux and there was always more than a handful of zope processes running. Now I switched to OpenBSD and there is only one. How comes? I guess the more zope processes I have running the more requests I can satisfy? --Ragnar ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

This is a 'normal' message. Zope 2.2 releases suppress the error message on shutdown. Not sure what's up with the tutorial.

We have an installation of Zope 2.1.6 running on Red Hat Linux 6.0 on an old 486/66 machine (a prototype serving some intranet content). We aren't doing any database connections on it (through Zope, that is), but we are running Squishdot (which is the main application in terms of usage on this particular machine). Zope is running behind Apache 1.3.9, and I noticed that multiple instances of Zope.cgi started up to service incoming requests, but apparently Zope wasn't responding. I just restarted Apache and everything was fine again. Is this a known problem with Zope that has been addressed in 2.2? Thanks.

[Zope] Patch to DateTime.py
Greetings, In my current project, I have to print a lot of dates. Fine, not a problem... _.DateTime().strftime() is just the method, right? Wrong. The people who want this site want the local time, not UTC+0 that strftime enforces. So, I created a tiny patch which adds _.DateTime().strfltime(), which works identically, except it passes LOCALTIME instead of GMTIME. It's tiny, it's simple, but it's REALLY HANDY!

[Zope] Stability - can you give us some advice?

In our company we are currently working to create a Web site with lots of dynamic content, database access, webmail, etc.. so we decided to try Zope. Although it's lack of documentation ( this would not be fair, with a search engine we can dig out lots of useful info from the web) we experienced a very fast development cycle. Now we're concerned about its stability. We are almost finishing the first stage of project and some times Zope hangs. It was working ok, and then, all of a sudden, it just stops answers requests. Last time it happend we changed a DTML Method to a DTML Document and it worked again (if you like i'll try to tell you exactly what was happenning). So, I'd like some advice to make it more stable.

Re: [Zope] Is Zope slow?
Hello, >I'm considering using Zope as the development tool for my next web >project. However, I read from a recent benchmark test (from Qube, i think) >that Zope(running thru Zserver?) is much SLOWER than Apache and >AOLserver. Is that true? To all Zope users and 'guru's, what is yr >experience using Zope? I run the QubeQuorner weblog where those numbers came from. Zope isn't slow. It's slower than Apache serving static pages. But Zope is dynamic. I haven't yet had time to do proper dynamic comparisons between the various servers. I run a few Zope sites. And I'm adding more Zope sites. I wouldn't do that if I thought it was too slow. There is a lot involved in making a site faster or slower. Adding a few graphics to your web page is going to make it slower than an all-text page. An all-text page vs a mixed text and graphics page can be almost twice as fast. Your connection to the site is going to affect "apparent" performance. For example, while I have a cable modem at home, and my Zope server sits on a fast T1 (there are slow T1s and fast ones), the connection in the evenings is too slow for me use my server. That's @Home's fault, not Zope's. And our T1 will fill up well before Zope runs out of steam on my box. Technocrat.net is a Zope site. They were Slashdotted and survived without any apparent problems. And they were running Zope on a Pentium 120! I believe they upgraded to a PII-450 after that episode, just to be safe. I have a list of Pystone benchmarks on my QQ site too: http://weblogs.userland.com/qube/stories/storyReader$289 A PIII-850 gives tremendous Python performance, which should translate to impressive Zope numbers too. Zope.org, however, doesn't run on nearly the fastest hardware available, and it rarely seems slow to me.

Data.fs only gets appended to, and Zope is smart enough to ignore incomplete transactions on the end of the file when it starts up.

Re: [Zope] newbie questions
AFAIK, it would be a bad idea a) if writes were not appends and b) if records written to the FileStorage were not written atomically. But neither is the case, so it's safe to just copy it without shutting it down. The only time this may not be the case is if it were copied during a pack operation.

[Zope] Unable to upload images from client to server
Hello All!
I have this problem with "UPLOADING".
In my HTML form (DTML-embedded-Document) I have data and images to insert
into a mySQL DATABASE. Therefore I'm calling SQL statements from my DTML
METHOD.
However, it seems the SQL insert command does not allow LOAD_FILE procedure
as does the SQL update command e.g.:
UPDATE table_name
SET blob_column=LOAD_FILE('full_path_of_file') WHERE
table_column='table_column value'
So I had to resort to using TWO separate SQL methods :
1) to insert the "data" alone into the database first, from the form;
2) then another to insert the image of the same form using the SQL "update"
command, verified my the data record's unique id.
All this works fine but this method does not work with the
<...ENCTYPE="multipart/form-data"...> value at the html form header.
Instead it only works with
<...ENCTYPE="application/w-xxx-form-urlencoded"...>. If I use
"multipart/form-data" it will enter the string of the command
LOAD_FILE('...file...') instead of the actual image contents. Why is this?
This is only one small part which I'm puzzled about as this method would
only allow images on the server's harddisk to be uploaded. The main concern
is UPLOADING from the client.
Having mentioned so, the next problem I'm facing is uploading the file onto
the Zope Server from the client. Having searched on the net, it appears
that I will have to use CGI's on my server side to temporarily grab the
files contents and place it somewhere. Is there anyway to use DTML without
the involvement of external CGI's?
Also, it seems that if I had to do this on Zope, it will require me to use
Python. Which of course sounds hard.
Then the questions arise regarding CGI's (IF IT REALLY IS REQUIRED):
1) How on earth do I do this?;
2) What if there were multiple users uploading files at the same time, then
what happens to the single temporary file which stores the uploaded files'
contents.
3) If I were to use a /cgi-bin/... how will that relate to where ZOPE is
installed, in other words, would the directory structures get confusing?
I'm not a hopeless programmer but neither am I close to even "quite good".
Learning won't be a problem, but I'll need the answers quick, as I do not
have the time in my hands. Can anyone please help me out?
I've looked in discussion forums and the DTML reference, as I have said I'm
practically a beginner programmer, and was unable to understand even half
of what had been posted.

Re: [Zope] newbie questions
Hi Frank, It sounds like your SourceSafe tie in could potentially be a fairly complex undertaking. Amos Latteier wrote an example COMObject product that will show you the mechanics of utilizing COM objects from Zope. This might help. And though I know you don't want to VC Zope objects, you might be interested in Steve Spicklemire's CVSMixin product that seems to utilize CVS for version control of several kinds of Zope objects. You may get tips from both of these products. Seach Zope.org for both. To back up the ZODB, just copy the Data.fs file in the var directory. You may safely do this while Zope is running. To restore, reinstall Zope and all the products you're using and copy the Data.fs into the var directory.

Hi, I've setup zope and zwiki to use for internal collaboration. I'm having fun and doing some useful stuff without knowing too much or appearing too stupid. I've decided to do something more adventuresome to learn some more. I'd like to tie in our SourceSafe version control system so I could do reports that list what has been checked in since a date or label. So I have to get input from the user from this and then use SourceSafe com interfaces to gather the data and put it in a nice format. Is this a good project for zope? It would be very useful for checking progress on projects when I'm off-site because using the SourceSafe UI over a modem has horrid performance problems. Along those lines would it be possible to use the Zope tree control to mimic the SourceSafe project tree stuff so the whole thing could be accessible using a modem?

The best thing someone ever showed me was how to view Not that you are wrong, but just a bit of clarification for those people who also haven't quite grasped the stateless nature of http transactions: it is probably better to say that the REQUEST object gets passed (by the DTML machinery invisibly or by calling dtml methods using the "methodname(_.None,_)" pattern) around between one *method* and the next.

[Zope] RE:How do I merge form & URL vars into sql easily
Hi Jake, I originally had trouble coming to grips with the concept of variables and forms and passing them from one object to the next. After much testing, trial and error (and guidance from this list), I came up with these conclusions (which I'm sure someone will shoot down if I am wrong): 1) The request object you are setting with your REQUEST.set command is like a big bucket that gets passed between one web page and the next when you call it in your DTML. The best thing someone ever showed me was how to view in the called document ie. insert the line: into the dtml/method you are trying to call. If you do that you can see all of the variables that get passed normally as part of your REQUEST variable, as well as any that get added to it by your form in the act of your POST command in the form. Be prepared - it is a long list! You should be able to see all your form variables in there. If you don't then you haven't been doing your form correctly (been there done that too!). The only real 'nasty' I have come across so far id the checkbox - if it is unchecked it doesn't post anything to the REQUEST object, and then you need to check for it and set it, if you are using it to update an SQL database (this is the only time I use the command. This is normal behaviour with forms and is not the fault of Zope.

Well, I find that Zope allows a MUCH quicker development cycle, along with various other advantages, such as remote edit of pages from any browser on the net. Yes, the documentation is lacking. However, IMHO, a competent programmer (especially one with a decent grasp of OO) will pick it up quickly with just a couple of reference documents. (The Zope Quick Reference comes to mind :) A friend of mine was a hardcore PHP nut, before I introduced him to Zope, and was amazed at how simple it made work.

You can use renaming to avoid any clashed.

If you want to prevent the outer loop value to be called,

I expect that your "date" looks like a string but in fact is an object. In this case, your error does not result from the "MyList[0]" but from th "_.string.split(date,'-')".

It means that "UuZ" is interpreted as a *column name*, i.e. as a field in your database and not as a string. This is because, it is not enclosed in '...'. Such a column does not exist; therefore, the invalid column name errors. Instead of "" you should use "". It does represent the constant string value correctly.

Notice the (potentially) essential difference:
In "callproc" you use "addarticle" (i.e. all lowercase),
but in "getSource" you use "ADDARTICLE" (i.e. all uppercase).
Maybe, case is essential.

Some days ago, I extended ZOracleDA with a method to call

ZOracleDA gives me a cursor. I used:
return cursor.procedures.()
worked fine.

Hi, We all know that Zope needs better docs. To this end we've added a help system, API docs and a tutorial to Zope 2.2. Now the important work of replacing the aging guides is job number one. Michel Pelletier has been diligently working on a Zope book for O'Reilly for a number of months. I convinced him to take me on as a co-author and turn the book into official Zope documentation. O'Reilly is on board and is currently choosing between two different open content licenses. Find out the full scoop on the Zope Docs Wiki. http://www.zope.org/Wikis/Docs/ZopeBook We're excited about the book and think that it will fill an important hole the current official Zope docs.

[Zope] Re: FSSession buglette
Paul Are you running FSSession0.4.0? If not please upgrade. The problems you mention below have been corrected. Nevertheless the first problem you descripe is not really related to FSSession. What happens is that certain Zope objects that can be pickled should not be stored in FSSession. Initially FSSession used marshal to serialize python objects, which is faster and does not allow storing of instances etc. I moved to pickle at the users request but one should be careful what he/she stores in FSSession. FSsession-0.4.0 should not raise an exception in tpc_finish. If I understand Zope's two phase commit mechanism, it is ok to raise an exception in tpc_begin (which corresponds to the 'polling' stage i believe) but not in tpc_finish.

The bottleneck is not generally the speed of serving webpages, but rather, the speed of the client downloading the data from webpages, as the data has to go through N regions of the Internet between the server and client. Also, users tend to look at more than one webpage at a time, and so their incoming bandwidth per connection is reduced even further.

[Zope] FSSession buglette
Hi All, I had some real problems with FSSession tonight. The first problem was when the FSSession tried to load, it would get an error along the lines of failed to import Acquisition. Next step was when the user session tried to rename and the file wasn't there. This threw in error in a Zope commit transaction, and rendered the site useless until a restart was performed (this was correct action by Zope, i.e. all commits are blocked to avoid the database becoming more screwed after a commit fails). First thing I did was put a try around the dump to stop it from throwing an error if the file doesn't exist. This is certainly a preferred option for us, as it does not affect the function of the FSSession at all (Except that one session is obviously now duff). Second thing in tracking down the culprit, I finally figured out that what I was doing was quite naughty. Basically creating an option for the user to return to the site and have his/her name already entered into the login screen. The mistake was putting AUTHENTICATED_USER into FSSession, it basically tried to store the object, when all I wanted was the string username! Oops!

I believe he is trying to do (in Java, because it's easiest for me to
express it, here):
public class StandardHtmlHeader
{
public String render() {
return "Hello, World."
}
}
public class SubStandardHtmlHeader extends StandardHtmlHeader
{
public void render() {
return super() + " Woohoo!"
}
}
Well, okay, not exactly, since we're talking acquisition not inheritance.
But, the idea is the same. He wants to display the previous
standard_html_header, with some additional stuff added, in his SubFolder's
standard_html_header.

I agree, again Im no expert, but from what I understand DTML is parsed into Python and then executed. You can skip that step altogether by not using DTML. I also find DTML is rather painful and anything involving 5 or 6 lines of DTML can be coded in *less* lines of more efficient Python! ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

I not to sure why you have gone down the route of doing all of this as
an external method? I would have thought that the form should be
generated from an DTMLDocument and a signal function in the External
method could do the file-stuff and return the success page, no real
need for the class at all. But, I guess you are just using this as a
learning exercise, so what do I know.
Zope can't find you signGuestBook function because it knows nothing
about your GuestBook class. The only thing you have told it about is
the ExternalMethod AddGuest. You could add another ExternalMethod
something like (code not tested):
def SignGuestBook(name,email):
myGuestBook=guestbook.GuestBook('My GuestBook', 'guestbookdata.txt')
return myGuestBook.signGuestBook(name,email)
then create a DTMLmethod call signGuestBook:
you will need to add the SignGuestBook function as an external method
in addition to the one you already have.
You can see from this that the creation of an instance of the
GuestBook class is pretty pointless because it only exists within the
scope of the function in which it is created.
Another thing to bear in mind (it caught me out recently) is that
ExternalMethods are load once when Zope is started (or they are first
called, I am not sure which) not every time they are called. This
means that any global variables you create are common to every
call. As Zope is multithreaded this may catch you out if you do not
consider it.
Hope this helps.

[Zope] Proxy Roles
Hi, i have a Problem using Proxy-Roles: i have following folders: /foo/ bar1/ comments/ TEMPLATE bar1/ comments/ TEMPLATE barN/ ... /make_a_comment/ submit >From a DTML-Method in "make_a_comment" I want to copy the folder TEMPLATE in a spezified comments-Folder and change some properties. I wrote a dtml-method called "submit": Now I want to use a Proxy-Role for "submit" to make it possible for everyone to add a comment with this method. I added the proxy-role "manager" to the "submit"-method. But if I access submit as anonymous, Zope still means, I don't have permissions to add a folder to /foo/barx/comments/...

The Zope core is *written* in python (with hotspots coded in python modules written in C), not just integrated with it. Since DTML must be interpreted by the Zope core (an interpreter running in an interpreter), whereas the python code in an external method is simply (more or less) executed (just one interpretation level), I would expect external methods and python products to be a lot faster than the same functionality coded in DTML.

Re: [Zope] zope/python startup error
I had that same error before as well. That had nothing to do with Zope, rather Python itself. The problem was that I had not installed TCL properly, and I reinstalled it. But, true, your drivers must have been confused when you installed this "shed-load" of Zope products. Try to reinstall Python (the one with IDLE) and let the installtion use the suggested paths for Python and TCL. I had some "problems" with the PythonWin. After having opened a fully functioning Python code in PythonWin, I could no longer use the following code. import sys sys.path.insert(0,'C:\Program\Zopesite\Extensions') ... so I commented this out and it worked perfectly fine as before in Zope.

[Zope] ZWiki with RemoteWikiLink - minor fix and remaining question
I needed to create 'proper' URLs with a remote wiki link, but ZWiki 0.6.1 only allowed things of the form ZWikiName:name-with-characters-only. I suppose my locale setting translates too many things to whitespace, but I'm not sure. A simple fix in the ZWikiPage.py file (sorry no diff here): find line interwikilink= r'!?((?P%s):(?P[\w]+))' % (wikilink) replace string [\w] by [A-Za-z0-9/:@_~#=\.\-\?] (note I couldn't include the % char because it seems to provoke the need for another string). Remaining question. Does anyone have a fix for the incorrect rendering of [notzwikiname] to nested URL notzwikiname or do I have to fix that for myself? This also fails to work as a remote wiki link, and I thought a fix for one might be a fix for the other also. Thanks.

[Zope] Newbe question concerning using python classes and external methods
All,
I am a new Zope user and I guess I'm missing something fundemental that I
haven't been able to glean from the documentation and various "How-to's".
As a learning tool I am trying to implement one of Brian Lloyd's examples I
found on the Web implementing a GuestBook.
I suspect what I don't understand is how to write the external method that
would make use of this class (The one I have been playing with follows the
class definitions). Anyhow, I've created an an external method and call
(e.g. ) after which the guestBookForm is displayed. After
filling out the form and submitting it Zope does not seem able to find the
signGuestBook method. What am I doing wrong??
Other than mostly trivial examples, I haven't been able to find many
complete (working) examples of using external methods.
Thanks in advance for any help.

Postgresql is a true object relational database which includes the ability to define transactions etc., MySQL isn't a true RDBMS. If you are serious about the back-end and your application includes the ability to update the database by more than one user concurrently then PostgreSQL is the way to go. It's also Open Source.

[Zope] Python or DTML
I know that Python is integrated _very_ closly to the Zope core, but to use a Python module you'll have to create an External Method and a file in the Extensions folder; and this might be slower than using DTML. Right? Basically, how much faster is DTML to Python (assuming the codes outputs the same thing)? The reason I ask is that I (probably as everybody else) want an as fast site as possible, but still use the power of Python. And also, whats the performance difference of using External python modules compared to the Python Method product?

Yes, you are right, we are using 8.1.5 On Linux, and it swallows up to 4k.

[Zope] Re:Web Site newbie
Tremendous reply!! Just what I needed. I'm curious about one thing tho. Does this mean that I have to have all my files in the zope folder? Wouldn't I want to do that anyway? Can you elaborate? I'd like to stick with the Zserver if I can but I don't want to run into any road blocks too soon down the road. -mjm winmail.dat

Thank you for your prompt response. This is what I love about using
Open Source Software, the responses come from peole who really know
what they are talking about.
Further responses in-line.

We had been doing some extensive development work and the ZDB had
reached about 2Gbytes, but the disk was not full. I packed the
database (down to 10M approx.) without any trouble. We then carried
on using the system for another two days and I then packed the
database again. This time I got the CorruptTransactionError. I
followed the instruction to truncate the database and successfully
recovered it. Close examination of the bobo_modification_times on the
objects left in the database showed that the error occurred at about
the time of the first pack.

Unfortunately the error occurred after (or during the first pack) the
second pack over-rote the Data.fs.old with the corrupt database. The
real problem was that the corrupt transaction did not have an
immediate affect.

I would love to send you the Data.fs file but unfortunately it
contents sensitive commercial information for my company and I would
be sacked for sending it out.
I know how difficult it is to track down bugs when people will not
give you repeatable examples, but I just can't send this stuff out.
