Re: [Zope] Q; Date / ZCatalog / Search
For an events database, I catalog properties "startdate" and "enddate" of
type "date" as field indexes; then I search it in two steps:
First create a temporary list of events that meet the date criteria
dtml-call "REQUEST.set('NewsEventsList',[])"
dtml-in "NewsEventCat(meta_type='News Event',
enddate=_.DateTime()-1,
enddate_usage='range:min',
sort_on='startdate')"
dtml-call "NewsEventsList.append(NewsEventCat.getobject(data_record_id_))"
/dtml-in
dtml-if NewsEventsListdtml-return "1"dtml-elsedtml-return
"0"/dtml-if
Then, if that list is non-empty, I format as many entries from it as I
need -- in this case 2.
!-- Start Events Summary --
table width="100%" cellspacing=0 cellpadding=0 border=0
dtml-in NewsEventsList orphan=1 size=2
trtd colspan=2p class="sidebody"
a href="/news/events"dtml-var startdate/a
dtml-if "_['startdate'] != _['enddate']"

Subject: [Zope] Q; Date / ZCatalog / Search
Kindest sir,
I have a small question I hope someone could share some wisdom
with. I am not that familiar with the various objects available
within the Zope framework yet.
.. I have made a ZCatalog which works seamlessly for text only
searches etc. However; I need to search on a date basis on the
generated object in the ZCatalog.
For now my "date" entry/column is [string] coded.. not "date"
as would be apropriate? How can I use date .. and then make
a search to get the last 5 entries in a table?
http://www.zope.org/Members/Zen/howto/AdvZCatalogSearching
.. shows some possible ways to do this; but I can't seem to get
them to work properly;
dtml-comment Items modified in the last 14 days
/dtml-comment
dtml-in "Catalog(bobobase_modification_time=_.DateTime(date)-14,
bobobase_modification_time_usage='range:min')"
New item:
dtml-var "Catalog.getpath(data_record_id_)"br
/dtml-in
.. does anyone have any information on how they have used this
and gotten it to work? .. and might have an example or two? ;)
What exactly does the various elements in the above example do?
.. like "Catalog(bobobase_modification_time=_.DateTime(date)-14,
bobobase_modification_time_usage='range:min')" ??
.. mm .. any input? ;)
Thanks in advance..

RE: [Zope] Win98 and WEBDAV - you ought to see it if you can
Aha! I got Web Folders to work when pointed to a Zope/Zserver on the same machine, so the problem is probably with the servers I tried to point to first. I found an explanation in an earlier email on this list: the attempt to access _vti_bin is an attempt by Web Folders to see if the server supports FrontPage extensions. It tries this if it thinks the server does not support WebDAV. It might think a Zope/Apache server doesn't support WebDAV if Apache doesn't have the patches necessary to let the WebDAV inquiry pass thru to Zope.

Re: [Zope] ZScheduler
Yes. The Client.py patch must be applied for any use of ZScheduler, if the server is not listening on the default port. "reschedule" is always called when an event is triggered, so that there is an opportunity to reschedule or disarm the event. If "reschedule" fails (as it will if the server is not on the default port and the patch is not applied), the whole transaction fails. By the way, what version of Zope are you using? I reported the bug in version 2.1.4.

Re: [Zope] Web site newbie
From: "Montagne, Michael" [EMAIL PROTECTED] I'm very excited about learning Python and Zope. I'm a win98 user and just today upgraded my service with my ISP to host my web page from home. Congratulations on becoming an internet host provider. I hope you have a firewall in front of your PC to help protect it from attacks over the internet. Does your ISP help out there? So I need a web server. I hope you realize that win98, while an OK platform for prototyping a Zope application, is not a sufficiently reliable platform for a professional website. But, because Zope is largely platform independent, most things you learn about it will be transferable when you decide to upgrade the webserver's operating system. According to the docs, Zope comes with one. If I use that one, am I going to be over my head initially? The ZServer that comes with Zope is about as easy to install as Personal Web Server. Go for it. Should I be using a different product if my site is not going to be super dynamic from the beginning? A reasonably fast PC has processor cycles to spare if all it is doing is serving a small web site. Users won't even notice that pages are being generated on the fly. If processor speed should ever become a limitation, you will have several courses of action that do not involve changing your Zope-based application (e.g. processor upgrade, front-end cache). If I use Personal Web Server, can Zope be integrated later? I don't think so (but I'm not positive). Still, if you need a regular web server, use the Windows version of Apache. It will be a little more complicated to install and maintain, but you'll be learning an industry-standard program. Subscribe to an Apache mailing list, if you need help managing it on your PC. If you don't need a regular web server (for serving files outside of Zope), stick with the built-in ZServer. Can I use Web authoring software such as Front Page 2000 and publish to Zserver? Yes (with limitations that you can read about by searching the archives of this mailing list), but you may find that you no longer want or need to. Usually 90% of the complex HTML in a web site is in the framing of the content -- i.e. the headers, footers, and navigation. This kind of repetive and/or computed HTML is the kind the you will program Zope to gather in one place, and reuse for all requests. The individual content of each page very often uses the simple sort of HTML that you can either code by hand or create in simple HTML-aware editors. thanks so much, -mjm -- Hope that helps -- Loren ___ 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 )

Title: Newbie: Zope a webserver? Serving PHP and Perl Your second question almost answers the first. You can use Zope either with or without Apache. One way to handle existing PHP sites is to put Apache in front of Zope. Then add configuration parameters to Apache to make it examine the URLs of requests. If the URL is for PHP pages, then handlethe request in Apache/PHP. If the URL is for Zope pages, pass it over to Zope. That way you don't even have to think about making Zope do PHP.

Re: [Zope] Importable Xron
Xron is alpha-level software, which means (among other things) that it is
new, hasn't received a lot of use, doesn't have a lot ready examples, may be
lacking documentation quantity or quality. If you want to use Xron in its
current alpha state you must be willing to invest a little effort in
learning to use the product. For my part, as developer of the product, I am
willing to guide you through the process on mailto:[EMAIL PROTECTED] and thereby
create a documentation trail here on the mailing list that others can use
and that can be distilled into more documentation and examples.
So if you are ready, so am I. But, for me to guide you, I will need to ask
you to be more specific about your experience level, what relevant documents
you have read, what specifically in the document you didn't understand, what
tutorials you have followed, what attempts you have made to use the product,
what errors resulted, etc.
First, to make repetitive events, you must create a ZClass. Have you read
the ZClass documentation and How-To's? Have you created a ZClass before? If
not, I recommend that you do so before we continue.
From: "Peter Bengtsson" [EMAIL PROTECTED]
I want to use the Xron product but I don't understand how to use it.
(http://www.zope.org/Members/lstaffor/Xron/)
All this Zope Zen jargon makes me dissy. What I don't understand is where
and why to put reschedules at certain places.
You have to create a ZClass that is just like Xron DTML Method class, except
that it calculates the time that the event will next occur based upon the
needs of your application. You create your ZClass in Control Panel /
Products. When you create your ZClass, you will be asked what classes to
base it on (subclass from); you must select Xron DTML Method.
If you do nothing else, your ZClass will behave exactly like Xron DTML
Method class. But you want it to do something different. You what it to
calculate the next time for the event. Xron DTML Method makes its default
calculation in the method 'reschedule'. You want to replace 'reschedule'
with your own calculation. You do that by adding a DTML method, named
'reschedule' to you new ZClass. There's a simple example in the README.txt
for Xron.
Subclasses and DTML
Methods...etc.
Can you please include a importable zexp on the download page of Xron.
I want to do one single simple thing for now.
Send the dtml-var webmaster constant information about various site
stats.
Do you already have methods that gather the site stats?
These should be sent weekly or hourly or monthly.
You could make a separate ZClass subclass of Xron DTML Method for weekly
events, another for hourly events, and another for monthly events. Or you
could create a single subclass that determines whether to reschedule for
next hour, next week, or next month. It's your design decision. I'd
recommend starting with just "next hour", as a learning exercize. That way
it won't take more than an hour find out whether your application works.
I also want to have more than one instance of Xron.
You probably don't want more than one instance of Xron. Xron contains three
major parts: the Schedule, the Dispatcher thread, the Xron DTML Method
class. Any single system needs only one Schedule and one Dispatcher thread.
What you probably need are multiple instances of the Xron DTML Method class
or of the subclass you create. Each one of these instances would be a
procedure that you want to execute at specific times. Suppose, for example,
your subclass of Xron DTML Method is called "Weekly Event" and its
reschedule method calculates the next event time thus:
dtml-call "REQUEST.set('XronEventTime', REQUEST.XronEventOldTime +
7.0)"
Then, you would create Weekly Event objects (also called "instances") for
each action that you want to execute weekly. Each Weekly Event instance will
be executed by the Dispatcher once a week. What a Weekly Event object
actually does when executed is determined by the DTML content of that
instance. You could have one Weekly Event that gathers, site statistics. You
could have another Weekly Event that sends you an email reminding you to
take out the garbage.
Can somebody give me examples. Especially how you set the date and time.
(I have no experience of cron and I live in GMT+0)
Experience with cron will not help you with Xron -- they are only similar in
general purpose, not in details of implementation nor interface.
You (because you are in GMT+0) can enter dates like this
August 9, 2000 14:27:00 GMT
Most common unambiguous date formats are accepted; for example
Aug 9, 2000 14:27:00 GMT
2000/08/09 14:27:00 GMT
9 Aug 2000 14:27:00 GMT
Detailed documentation is in ../lib/python/DateTime/DateTime.py

If you want to use Xron in its current alpha state you must be willing to invest a little effort in learning to use the product. For my part, as developer of I think part of the problem is that there are increasing numbers of people with limited Zope knowledge, and an overwhelming number of Zope products without any indication of how difficult it is to use a particular product. Perhaps Zope product writers should rate their products with a difficulty scale. I think only the users of the products could do that usefully. Developers are biased. How about if DC puts a rating form on every product page on www.zope.org, so that users can vote ;^) (Just kidding, really.) And regarding the original question, how difficult would it be to modify your Xron product so that the periodicity is an attribute of the product rather than having to sub class it? Depends on what sort of periodicity your application needs -- and therein lies the problem. There are so many different needs that a built-in general purpose interface for specifying periodicity is likely to be at least as complex and hard to explain as a programmable interface. Take the Unix command 'cron' for example. I've included its man page below. Is that easy to understand? No way! Now imagine writing the Python/DTML code to build a nifty point and click interface to it. Not this boy! Now, if you or someone else wants to take on the challenge of building a cron-compatible rescheduler interface, be my guest. I've done my part. You can subclass Xron DTML Method. Sure, it would be possible to create a simple property that selects Weekly, Hourly, or OneTime. ...with maybe a corresponding check-box in the management interface. As soon as I published a simple system like this, the requests would start coming for more and more capabilites, and the interface would grow without control. For example, suppose you want to add Monthly to that list. Now you have to answer the questions "What kind of month -- calendar or accounting? ... which accounting system?" So, if I were going to create this kind of interface, I'd do it in a subclass, anyway, so as not to clutter up the base Xron product with something that is likely to change frequently. So how about this: I invite other developers to create rescheduler sub-products for Xron. If you create a rescheduler product, let me know about it, and I'll link to it from the Xron product page. Your product could be a Python product or a ZClass product. There's probably room for something like "Simple Rescheduler for Xron", which would do Weekly, Hourly, and OneTime; and "Cron for Xron" which would be a full cron-like interface; and maybe a product of intermediate complexity. The "Simple Rescheduler" would make a good first-time ZClass project. The developer would need to know how to write a ZClass, how to handle PropertySheets in a ZClass, and how to use DateTime. Does this sound like a good plan or a bad one? Any takers? -- Loren = man cron = The format of a cron command is very much the V7 standard, with a number of upward-compatible extensions. Each line has five time and date fields, followed by a user name (with optional ``:group'' and ``/lo- gin-class'' suffixes) if this is the system crontab file, followed by a command. Commands are executed by cron(8) when the minute, hour, and month of year fields match the current time, and when at least one of the two day fields (day of month, or day of week) match the current time (see ``Note'' below). cron(8) examines cron entries once every minute. The time and date fields are: field allowed values - -- minute0-59 hour 0-23 day of month 1-31 month 1-12 (or names, see below) day of week 0-7 (0 or 7 is Sun, or use names) A field may be an asterisk (*), which always stands for ``first-last''. Ranges of numbers are allowed. Ranges are two numbers separated with a hyphen. The specified range is inclusive. For example, 8-11 for an ``hours'' entry specifies execution at hours 8, 9, 10 and 11. Lists are allowed. A list is a set of numbers (or ranges) separated by commas. Examples: ``1,2,5,9'', ``0-4,8-12''. Step values can be used in conjunction with ranges.

[Zope] Re: concerning Xron with DA
From: "Nicholas Lo" [EMAIL PROTECTED] I just wonder if Xron works with ZSQL Methods. I know that ZSQL Methods only works with the request thread. Thanks. I can think of no reason Xron would not work with ZSQL Methods; but I haven't tried it, because I have no SQL in my applications. Xron's dispatcher thread does not directly run scheduled methods; it uses Client.py to fabricate a request. So the scheduled method runs in a request thread, just as an ordinary client request. Scheduled methods are a subclass of DTML Method, so the scheduled method would have to call your ZSQL Method. There is currently no way to pass parameters to the request. If the ZSQL Method requires parameters, the scheduled method must supply them from its context. Would you like to be the first to try it out and report back to the mail list?

[Zope] Re: Xron test
Nick, Two other Zopistas reported similar problems. Both succeeded eventually in getting Xron started, but we didn't succeed in diagnosing the problem, nor in determining precisely how to work around it. I myself haven't been able to reproduce the problem. The problem seems to occur only on Linux, but it does not always occur. Some users have successfully started Xron on Linux with no problem. The problem seems to have to do with contention for a lock on ZODB. Did you see any log or console message that would confirm this? One user went to the console and killed all the Zope processes that were running at the time, then restarted Zope from the command line. The second time, Zope started up correctly with Xron. Another user thought that he had mistakenly tried to start Zope while logged in as root. When he restarted as a different user, Zope started up with Xron correctly. I suspect that the user was not relevant to the Xron problem (it is normal in some installations to start as root), but that the restarting was the key. One user thought that the monitor process contributed to the lock contention. I don't know, but it might be worthwhile to try to restart Zope without the monitor (changing the start-up options to disable the monitor). The problem seems to relate to Xron's creating the Schedule catalog the first time the Xron product is loaded during Zope start-up. If you succeed in creating the Schedule one time, the problem will not recurr, as Xron will just use the existing Schedule. I hope that helps you get started. Let me know how it goes. I'll copy this email to the zope list in hopes that someone else can shed some light on the problem. -- Loren - Original Message - From: "Nicholas Lo" [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: August 18, 2000 12:41 AM Subject: xcron test Hi Loren, I have a problem with installing Xron 0.9 onto my machine.

Re: [Zope] sending mail slow?

Why is that? how can I make it faster? I'd thought about having the actual mail sending done in a different thread/process but I don't know how I'd do that or whether it'd be worth doing.

[Zope] Xron and Security [was ZScheduler and Pack]
From: "Marcus Mendes" [EMAIL PROTECTED] Is it a security risk to leave the Zscheduler pack my Data.fs? I don't have an answer, but I can clarify the risk. We can use packing Data.fs as an example application, but the question about security is more general. Xron (formerly ZScheduler) does not currently provide any features that deal with security. Scheduled methods are called thru the Client.py interface (i.e. by handing a URL to Zope as if it had come from a browser client). For example, suppose you have a scheduled method "Packer" in the root folder that calls the management method that packs your database. The URL that the Dispatcher of Xron uses to execute that method is simply: http://www.mysite.com/Packer/trigger Client.py is capable of passing authentication information in the request; but because Xron does not (yet) supply authentication information, a scheduled method must be executable by an unauthenticated user. If the scheduled method performs any privileged functions, then the method must have proxy roles that give it sufficient privilege. (I'm not sure what role is required for manage_pack, but there must be one.) Therefore, any user (who happens to know about your method and about Xron's calling convention) can pack your Data.fs simply by keying http://www.mysite.com/Packer/trigger into a browser. Suppose an unscrupulous person (who happens to know about your method and about Xron's calling convention) created a program that would make a request to http://www.mysite.com/Packer/trigger once every N seconds (easy to do with Xron!). Could that bring your system to its knees? ...any worse so than any other repeated request? I don't know the answer. If I were you I'd try it out. Can anyone see any other security vulnerabilities here? I'd be glad to listen to well considered proposals for how Xron should handle security. -- Thanks -- Loren ___ 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 )

Re: [Zope] Where do I find out about cookies?

It looks like I'm going to be using cookies now, and I don't find any
How-To on cookies. What's the most instructive place to look? "UTSL" is
fine as an answer, especially if it points me somewhere, and even more
if it's DTML source ..
The *ZQR* is a bit too cryptic for me.
First you must understand cookies independent of Zope:
http://home.netscape.com/newsref/std/cookie_spec.html
Then Zope's interface to them will be easier to understand:
The *DTML Ref* has a bit more::
8. Dictionaries are objects that support looking of data by name
(e.g. REQUEST.cookies['CUST_ID'] to look up a cookie named CUST_ID).
Dictionaries have has_key methods for checking whether a dictionary
contains a value (e.g. REQUEST.cookies.has_key('CUST_ID') ) and
methods keys , values , and items , for updating lists of dictionary
keys, values, and key-value pairs (e.g. REQUEST.cookies.keys() to
obtain a list of cookie names).
.. but I don't understand yet how 'keys', 'values' and 'items' are going
to help me *update* the lists -- it seems to refer only to querying
them, AFAICS ..
Search for "cookie" a little further in
http://www.zope.org/Members/ZQR/zqr/normal and you will find not only
REQUEST.cookies but also RESPONSE.setCookie().

You access them as simple DTML variables: e.g. dtml-var form_field_name If you want to send the value of that form field on to another form, you do it much the same as in Perl -- you code a hidden form field and assign it the value dtml-var form_field_name. -- Hope that helps -- Loren - Original Message - From: "Amit Redij" [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: August 28, 2000 04:45 AM Subject: [Zope] Newbie question: FORM processing in Zope. hi, I am a Perl/CGI programmer, trying out Zope.

Re: [Zope] Non-blocking MailHost
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. http://www.zope.org/Members/lstaffor/Xron -- HTH -- Loren - Original Message - From: "Richard Taylor" [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: September 04, 2000 08:11 AM Subject: Re: [Zope] Non-blocking MailHost 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.

[snip] I see 5 solutions: 1 - store both files and their associated datas in ZODB 2 - store files in the filesystem and datas in ZODB 3 - store files in the filesystem and datas in an RDBMS (use Zope only for the presentation of files and datas) 4 - store files in ZODB and datas in an RDBMS. 5 - don't use Zope at all because it's not appropriate. In general, large file uploads thru HTTP are clumsy. The browsers don't provide progress indicators. Broken connections occur due to timeout under network congestion but the browsers don't handle broken connections well. And (as far as I can tell) the entire request (including the entire file) is buffered in the OS swapspace. Some site I saw recently (was it xdrive? I'm not sure) uses client-side Java to manage the upload. I chose #2 for a similar application and ran into these additional issues: 1. A file upload done thru Zope into the filesystem passes thru a temporary file. This increases slightly the apparent upload time, while you copy the file to its final destination. And, you must also ensure that the partition where temporary files are placed has enough space for the maximum file size. 2. You must also decide how you are going to serve the file. Since it's in the file system, you could serve it directly thru Apache (perhaps thru a redirect initiated by Zope), thereby avoiding occupying a Zope thread for a long time for every downlaod. But if you take this approach, you must somehow make Apache apply the same access control to the file that you have in Zope. This can be done, but is an added complication. -- My .02 -- Loren ___ 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 )

Hi Loren
(sorry for my "approximate english":)
There is a good news in this matter.
I'v noticed that in Zope 2.3.0b1 was included stricte similar way
as my patch.
Only names of variables was changed:
My name of variable was sort-python, now exists sort_expr
Additionally DC guys added reverse_expr variable.
Here is a example of use (from my patch but translated to use sort_expr)
dtml-call "REQUEST.set('sortstrvar', _.string.lower('tItLe')+','+'id')"
html
pre
1."Hardcoded"
===
dtml-in "objectItems(['Image'])" sort=title,id
dtml-var iddtml-var title
/dtml-in
2.Indirectly
dtml-in "objectItems(['Image'])" sort_expr="'title,id'"
dtml-var iddtml-var title
/dtml-in
3.Indirectly
dtml-in "objectItems(['Image'])" sort_expr="sortstrvar"
dtml-var iddtml-var title
/dtml-in
4.Indirectly
dtml-in "objectItems(['Image'])"
sort_expr="_.string.lower('tItLe')+','+'id'"
dtml-var iddtml-var title
/dtml-in
/pre
/html
I'm trying to provide user-specified sorting on the records I pull from a
SQL database. When the user specifies sorting on Department, I assume he
wants the records order by Name within each department, but I can't see
how
to do that with ZSQL or dtml-in.
User would specify multiple keys sort (dr Lazarus patch which is included
to core from Zope 2.2.2 (?))
eg:
dtml-call "REQUEST.set('usersort', 'department,name')"
html
pre
dtml-in recordset sort_expr="usersort"
dtml-var departmentnbsp;dtml-var name
/dtml-in
/pre
/html
But best news for you is that sort_expr patch may be very
simply implemented for Zope 2.2.4 and 2.2.5
Simply copy the file:
Zope230b1/lib/python/DocumentTemplate/DT_In.py
to
Zope224|5/lib/python/DocumentTemplate/DT_In.py
thats all you need :)
It is possible because nothing else except sort_expr patch
was changed in this file, without dependences and influences
for other pieces of Zope

I found some time to do a little work on ZScheduler. The result is alpha version 0.0.5. You can get it at http://www.zope.org/Members/lstaffor/ZScheduler. It appears fully functional on Win98 with Zope versions 2.1.4 and 2.1.6 (with patch to Client.py). But this is still alpha software, so be careful where you install it. I've made no changes to make it work on Unix. (I don't have a Unix development environment at my disposal.) Prior versions caused Zope to become inoperative while installed.

[Zope-dev] Logging for ZScheduler?
I need some advise for designing a flexible system for logging the activities of scheduled events. One of the motivations for developing ZScheduler was to have a platform independent means for scheduling Zope tasks. The lask of a cron on Windows platforms was a part of the problem. ZScheduler achieves this independence by using Python's threading.Wait method for all time measurement. But ZScheduler also needs to be ISP independent. That is, you should have complete scheduling capabilities for your cohosted Zope applications without having to call up the ISP and ask for system configuration changes. ZScheduler partially achieves this level of independence, by eliminating the need for cron. But, as I installed ZScheduler under my personal account at CodeIt Computing, I realized that an ISP-dependence still exists, and it has nothing to do with cron -- it has to do with the configuration of the Scheduler's logging activity. When you have a Scheduler executing applications tasks on your website behind your back, you definitely want it to keep a log of what it is doing. For ZScheduler, I chose to use the STUPID_LOG_FILE feature of Zope. However, STUPID_LOG_FILE is an environment variable. Zope accounts at CodeIt (and probably at any other Zope ISP) cannot set environmet variables. And if they could, is anyone certain how STUPID_LOG_FILE would behave in their custom cohosting adaptation of Zope? So, I need a more flexible structure for the logging aspect of ZScheduler. While the ZEvent class is subclassable by users, I haven't made the Scheduler class instantiable -- there should be only one instance -- so it's not subclassable either, and therefore you can't override its logging method. Do you see the problem? Having little experience with Python and OO applications, I don't know how others solve this problem. Can you give me any pointers? Perhaps I've identified a typical application of RIPP? -- Thanks -- Loren ___ 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 )

You could just call Zope's logging system and move it out of the scope of your product. Have a look at zLOG.py or LOGGING.txt if you havn't already. Means people can extend their logging system to their hearts content with no effect on your product. ZScheduler already uses zLOG.LOG. I guess I forgot that it permits implementations other than stupid_log. So I guess ZScheduler is as flexible as can be, given the current API. But ZScheduler also needs to be ISP independent. That is, you should have complete scheduling capabilities for your cohosted Zope applications without having to call up the ISP and ask for system configuration changes. This could be achieved with a seperate product. A product that ties into Zope's logging infrastructure and allows viewing the log files through the web. All it would have to do is append itself to the ZLogger.loggers tuple, and the interface is pretty trivial. And of course, it means that other products can use it without modification (Logger product, Zope itself etc.) and can be extended as required without having to submit patches to you for inclusion in ZScheduler. Aha! Even tho a cohosted account might not be able to modify the source of the Zope implementation directly, installing a CustomLog product could do so indirectly, by importing ZLogger and modifying the loggers tuple. To know where to write the log file, CustomLog would have to either know or be configurable enough to adapt to the ISP's Zope configuration. I suppose an absolute path property would be suffient. An ISP could preconfigure and preinstall the CustomLog product for all users, or each user could do it. It would be a good idea if there was a field in the ZEvent that defined the subsystem used in the zLOG call. I didn't follow your point here. By "subsytem" do you mean which logger in the loggers tuple? Then do you mean that different ZEvents could log to different loggers?

Re: [Zope-dev] Logging for ZScheduler?
I've created a STUPID_LOG helper product, called FrozenLogger, that does the
minimum necessary for me to create a STUPID_LOG_FILE at my account at CodeIt
Computing (where lack of telnet keeps me from setting environment
variables).
http://www.zope.org/Members/lstaffor/FrozenLogger
The core of this is:
from Globals import data_dir
if os.environ.has_key('STUPID_LOG_FILE'):
pass
else:
os.environ['STUPID_LOG_FILE']=string.join((data_dir,'FrozenLogger.txt'),'/')
It works for me at CodeIt, but I doubt if it's general enough for some of
the Zope virtual hosting schemes I've read about here. Let me know how your
mileage varies.

[Zope-dev] Re: Objet : Re: ZScheduler-0.0.5 problem
This is going to be hard to debug remotely. Can you help me out? First try getting ZScheduler 0.0.6 which fixes a problem of non-responsive Zope, though there the problem was on shut-down not on start-up. Be sure you have STUPID_LOG_FILE working. Then uncomment some of my debugging statements (calls to loggerr) in the source of __init__.py and Dispatcher.py -- maybe add some instrumentation yourself -- all with the goal of observing how far it runs before Zope hangs. Maybe you'll have to activate one of the #import pdb; pdb.set_trace() statements (in an appropriate place, of course). Also, are there any entries in the Zope log or system log that are seem relevant?

[Zope-dev] Re: [Zope] ZScheduler-0.0.6 problem
Could we continue this discussion on zope-dev, because this is an alpha-level product at this point? I have ZScheduler 0.0.6 running on a Linux machine (www.fippless.org at CodeIt Computing), so we can't say it's an NT vs. Linux problem. It's more likely a Linux/Python/Zope configuration issue. The most system-dependent part of ZScheduler is its use of Python's threading module. According to Netcraft, www.fippless.org is running Red Hat Secure/2.0 (Unix) mod_ssl/2.0.7 SSLeay/0.9.0b on Linux. According to the Zope Control Panel, Zope version: Zope 2.1.3 (source release, python 1.5.2, linux2) Python version: 1.5.2 (#1, Feb 1 2000, 16:32:16) [GCC egcs-2.91.66 19990314/Linux (egcs- System Platform: linux-i386 Nick, can you supply more detail about the Linux configuration? CodeIt Computing is a good Zope ISP, but, as you would expect of an ISP, they don't offer facilities for this level of SW development, and I don't have any other machines at my disposal to duplicate your Linux configuration. So, I'll need your assistance to help isolate the problem. Can you help with a little debugging, tracing, instrumentation to find the code that throws Zope off track? I doubt whether the problem is with the archive itself, but just to be sure, I created a new archive for version 0.0.6 with a different archiving tool.

[Zope-dev] Announce: ZScheduler alpha Version 0.0.7
ZScheduler Version 0.0.7 Date: 2000/07/02
1. Fixed a bug that caused ZEvents to execute in the wrong context.
2. If the action method of a ZEvent raises an error, a traceback is written
in the log.
3. Added a Trigger tab to the management screen for ZEvents which fires the
event in the same context that the Dispatcher does, but without regard to
the schedule. This helps immensely in debugging the DTML in the ZEvent.
I've tested on:
Win98 Zope 2.2.0b3
Solaris 2.6 Zope 2.1.4
Linux ?.? Zope 2.1.3
On the Linux configuration (my account at CodeIt Computing), most features
work; however, the new Trigger tab does not behave correctly. Though the
ZEvent method eventually executes correctly, it doesn't return anything to
the client and Zope seems to lock up temporarily -- that is, it doesn't
respond to other client requests. I don't have a Linux development system
with which to track this down. Any help would be appreciated.
Here's the code for the Trigger tab. Can you see anything wrong? ...or
anything Linux and Zope 2.1.3 would find wrong?
def manage_triggerZEvent(self, client=None, REQUEST=None, RESPONSE=None,
**kw):
"""For use by the Trigger tab on ZEvent management page.
Use for testing the ZEvent in a context that mimics that of Dispatcher.
"""
RESPONSE.setHeader('Content-type','text/plain')
aurl=REQUEST['URL1']
furl=string.join((aurl, 'trigger'), '/')
(headers,response)=Client.call(furl) # Fire event
RESPONSE.setBody(headers)
RESPONSE.appendBody('\n')
RESPONSE.appendBody(response)
Otherwise, ZScheduler is looking good. Let me know how it works for you.

Re: [Zope-dev] Announce: ZScheduler alpha Version 0.0.7
The problem noted below with the Trigger tab occurs only when Zope is limited to a single thread. The problem is due to contention for the single thread.

But given that the python lib that Client.py uses for http (httplib.py) doesn't support https, then you're right. Solutions? 1. Permit http traffic to your site if it comes fromt the same IP and is for URLs that end in "/trigger". I suppose that IP spoofing makes this something of a security hole. How bad? 2. Enhance either Client.py or httplib.py to support at least enough https to get the job done. I know nothing about this. Is it reasonably doable?

Re: [Zope-dev] Xron and security
Thanks, Steve. I have few questions below 8-) (I'm always better with questions than answers.) -- Loren From: "Steve Alexander" [EMAIL PROTECTED] Hi Loren, I'd be glad to listen to well considered proposals for how Xron should handle security. Consider this a "straw man". On installation, Xron creates a user in the root user folder called "XronUser". Xron is resonsible for setting this user's password. Therefore, it is known to both the Xron product, and also to the root user folder. When a Xron method is run, there is a property that indicates whether it is called anonymously, or authenticated as XronUser. Is there a good reason not to always pass authentication in the request? The authentication property would have to be stored in the Schedule catalog, and I'd like to keep the Schedule as small as possible. The Xron product could change the password of XronUser every day to a new random value. That's more than folks do to maintain secrecy of the "superuser" password. Is the extra trouble worthwhile? The domains associated with XronUser could be just localhost.localdomain (not sure about this). Or based on whatever the machine's host-name is (probably better). At a virtual-hosted site, how could Xron know what the host-name is? Site administrators can assign local roles to XronUser as necessary. If Phillip Eby's proposed changes to the access file get included in some future version of Zope, XronUser could be included as one of these bootstrap users by simply writing to a file. -- Steve Alexander Software Engineer Cat-Box ltd http://www.cat-box.net ___ 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 )
Re: [Zope-dev] Xron fragility
From: "Kapil Thangavelu" [EMAIL PROTECTED] [snip] Xron has a single dispatcher thread. This thread knows how long to sleep for until the next job needs to run. this model has problems when new jobs (for immeadiate execution) are entered after the system sleeps. i think it should it taken into account that people will use this dispatching thread to achieve async operations on a request, and that these might need to be done immeadiately. This is not (or should not be) a problem in current Xron design. The Dispatcher wakes up early if the Schedule catalog is changed. -- Loren ___ 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 )
Re: [Zope-dev] Xron fragility
What if you want a small job to be done every 30 seconds? I generally don't... I'm satisfied with cron granularity, although others might not be. Do you have this requirement? I thought a little about the granularity issue and decided to go with the most general solution. I have no requirement for 30-second intervals, but I wanted to avoid support requests from those who might have such a need. Also, I have no need for large numbers of scheduled methods. But I used a heavy-duty data structure (Catalog) and the sleeping dispatcher model, just so there would be no arbitrary limits that would cause me support headaches later. It uses Client.py to run a job. Why is this? This doesn't make any sense to me on its face. Why not just call the method from a separate thread? Which separate thread? Do you create a new ZODB thread? That sounds as if it might use quite a few resources. Is there a Zope API for making ZODB threads call methods on objects, as signalled by other threads? I'm guessing the easiest way to do that is to use Client.py to make a new http request. Yes, using Client.py was the easiest way to do that. The biggest problem with Client.py is its dependency on HTTP. If your server is set up to only accept HTTPS, then you can't use Xron -- not a desirable trade-off. We need another mechanism that achieves the same goal -- simulating the environment of a request -- without going all the way back to the socket. -- Loren ___ 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] Future of Xron and method scheduling in Zope
I would be happy to turn development of Zope scheduling capabilities over to someone else, because I currently have no demand for scheduling capabilities and am not actively working on Xron.

Starting a new product from scratch, without reference to the Xron product. The new product could carry a different license. I would be happy to give up the Xron name, in this case, if anyone wanted it for the new product. 3. Building scheduling capabilities into Zope core.

RE: [Zope-dev] Xron error!!!
1. If you can use the management interface, you can disable a Xron Scheduled Method by deleting it from the Schedule catalog or setting its reschedule interval to null. 2. If you delete (or just rename __init__.py to something else in) the Xron Product. And restart Zope, there will be no Dispatcher to execute Xron Scheduled Methods; so looping will stop. 3. The messages in the log file should indicate what kind of error the Xron Dispatcher is encountering. If this is some kind of environmental condition, perhaps you can fix it external to Zope and the Dispatcher will stop looping. 4. The Dispatcher is designed to cancel erring Xron Scheduled Method, precisely so that it will not go into a loop. The fact that it seems to be looping indicated some very unusual condition. Please let us know what the log file says. 5. You can truncate the bloated tail end of a Data.fs file using standard system tools. I don't remember how right at the moment, but a search in the mail archives on trucate and data.fs might be fruitful. Don't throw away the original file, because you might truncate other transactions that you wanted to save. IOW, finding the right spot to truncate is the trick. -- HTH -- Loren -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Espen Sorbye Frederiksen Sent: Thursday, May 24, 2001 13:06 To: [EMAIL PROTECTED] Subject: [Zope-dev] Xron error!!! My Xron file has gone crazy and does not stop running. I have stopped my server and started it again, but the xron file is still running. This causes the Z2.log file and Data.fs files to grow to enormous files and I struggle to be able to log into the system. First: Can I delete the overloaded Data.fs file in the var/ directory, or will this cause serious trouble? Secondly: Is there a cure against that void Xron file of mine or must I manually delete it from were my own files are stored?

[Zope-dev] Manage Interface
Does DC plan to have site developer make their own management interface? The site-developer wouln't mind using the management interface for their work, but most of them will reject the common users using it. Of cause there were security issues also. Allow the site developer to make new interface on specific branch of the object tree will easy their jobs. Using basic Zope, yes. If you want end-users to manage content in any way, you have to create the end-user interface and expose the underlying management interface through it as you see fit. The Content Management Framework (CMF) Zope product ([EMAIL PROTECTED]) is another approach for portal-like environments. CMF is specifically designed to delegate content management using a common, more user-friendly interface. -- Loren ___ 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 )
RE: [Zope-dev] Does creating REAL over-the-web Python code become realistic with Zope 2.4?
Coincidently, I was just trying to edit a file on the filesystem with an FTP client going thru Zope/FTP and a LocalFS. It didn't work. The LocalFS instance didn't look like a directory to FTP so FTP could neither read nor write to the directory. Does that throw a monkey wrench into your idea? -- Loren -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Joachim Werner Sent: Thursday, May 31, 2001 15:54 To: [EMAIL PROTECTED] Subject: [Zope-dev] Does creating REAL over-the-web Python code become realistic with Zope 2.4? Hi! When I read about the reload functionality of Zope 2.4, an old vision came back to my mind: If we can reload Python code at runtime, and we can also edit, generate and store files (containing code) via the web (as LocalFS or extFile prove), then it should be perfectly possible to have something like ZClasses (it terms of the over-the-web front-end) that spits out and dynamically loads REAL Python classes instead of the rather experimental simulation of classes we get with ZClasses, right? I'll skip the part about why we should not be able to manipulate Zope code over the web, which can be discussed separately ... What do you think about this idea? If it finds some friends, I'll set up a formal proposal for something like ZClass-like features to build REAL Zope Python classes over the web.

RE: [Zope-dev] a beginners question ...
The quick answer is Yes. One method is described by http://www.zope.org/Members/lstaffor/ZClientMethod. You can also use XML-RPC. On the other hand, Zope is an integrated programming environment for web applications. It includes the capabilities offered by servlets within its programming system; DTML methods, Script (Python), Script (Perl), SQL Methods are all servlet-like functions. So you might ask yourself whether you couldn't do better inside Zope what the servlets are doing for you outside Zope. -- Loren -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Brian Gorrie Sent: Wednesday, June 13, 2001 18:01 To: [EMAIL PROTECTED] Subject: [Zope-dev] a beginners question ... Hi, Forgive my lack of Zope knowledge I am fairly new to Zope. Question: From zope can I take a block of text returned by a web link ( say some dhtml returned by a servlet ) and include that in the source of a web page. So I can build the sections of a web page through successive calls to Servlets ?
