[Zope-dev] Re: ZCatalog fast as admin, dog slow as anonymous and other users
Tres, I updated the DateIndex.py file to the one from the current 2.6 head. But I'm still getting the 'integer multiplication' error. Is there another possibility? Also, it only does this for the 'expires' index. The 'effective' index reindexed just fine.

Re: [Zope-dev] Re: ZCatalog fast as admin, dog slow as anonymous and other users
Tres,
You are right. I've also got that permission turned off to take
advantage of that part of the CMF workflow, which compounds the problem
since it's site wide. I'm building the individual DateIndexs now and
when that's done, I'll check the performance (for my own edification if
nothing else 8-). Then I'll add that DateRange index and patch the CMF
and check again.
Do you guys want metrics? If so, preferred tool/output method?
(although my guess is, you already know how spiffy this makes things 8-)

This symptom probably has to do with the login in the CMF catalog which
filters results based on the effective - expiration dates, for anybody
without the View inactive content permission. I would guess that your
portal_catalog is *not* using a DateRangeIndex to filter such content,
but is still using the individual 'effective' and 'expires' indexes.
To fix this:
- Add a DateRangeIndex, 'effectiveRange', to your portal_catalog;
set its start attribute to 'effective' and its stop attribute to
'expires'.
- Patch CMFCore/CatalogTool.py using the attached patch file (made
against the released 1.3 version).

As for multiple DB rollback, yes, that works as advertised, and is actually really easy to believe if you explain them how it works. Truth is, Two-Phase-Commit was INVENTED (a long time ago, and not in Zope) to make it possible to commit or rollback multiple transactional entities at the same time. Zope is just an implementation of a TPC coordinator (I think, and I hope I got the vocabulary right). In the course of a Zope transaction, any object that is invoked and wants to be notified of the tpc phases registers itself in the transaction machinery. Most of them inherit from Shared.DC.ZRDB.TM.TM. When a transaction is aborted or commited, the Transaction machinery notifies all registered objects. Each registered object then calls the respective actions in their backend drivers or whatever.

Re: [Zope-dev] PHP vs Zope cost benefit
Curiously, if there are prepackage scripts for both, and there's less to 'mange' with PHP, that's a PHP win. I personally have CalendarTag, ZDataQueryKit and lots of yummy others runing from the downloads page. But since I'm trying to convince PHP people that using Zope is better, they just point to their yummy scripts too. I think Oliver's point about transaction safety is a big win. I might convince them just on that. But I'm still looking for more ammunition.

But whatever ends up in the core, there are many, many good add-ons already out there. Bill -- The commandments of the LORD are right, bringing joy to the heart.

Re: [Zope-dev] PHP vs Zope cost benefit
Dirk, Thanks for that. By 'separation' I'm assuming you mean ZPT, correct? I'm new to that, but the virtues seem to be simple edit and save for layout folks. With PHP, you can create forms to publish content. You don't have to give content mamagers PHP. Zope's a win for Designers, for sure. Right now the designers are the coders, so that's more like an 'eventual' win. The database logic can be separated with PHP by just creating some php 'backend stuff' and calling those database functions you've created from the 'presentation' scripts. Just like calling a ZSQL method from a DTML method. As long as you kept the exposed calls the same, you could change Databases. It probably wouldn't be as easy to step to Oracle if they wanted to. You are right about that! ;-) On Tuesday 23 April 2002 11:24 am, you wrote: Hi Jason, what about a mix content-management-system and application-server in one server: - Zope + EasyPublisher you have a special layout. realizing that in php means editing php with html. with zope you can make application logic here and layout (presentation logic) there. you have lots of unique structured content: you can seperate the database logic from html very simple you have no limitations on the underlaying database engine, just remove the db-connector and put a new one in. we currently plan out new intranet with zope. had php content-management as an alternative, but we can't give php to our users. question you should answer to your self: which users have to work with your system in your company ? which user change things in the system ?

Re: [Zope-dev] PHP vs Zope cost benefit
Thanks Lennart, There is OO php now, which they seem to enjoy. ugh The audited security is something I believe is big win. The quickness and efficiency of Zope Corp's (still calling them DC in my head) Zope security patching is outstanding. The community really shines there. With undoable transactions, are transactions that have taken place in the Postgres Database really undo-able by undoing the Zope transaction that made them? For users, they'll be stored in Postgres, so is LoginManager (which uses the venerably weighty ZPatterns) the best way to go, or is exUserFolder sufficient for scaling to largers numbers of users? I'll ask the Jester about that directly is no on has a quick answer. The front end user/roles permissions thing is a bit hard to manage sometimes, honestly. But it's there at least, and not in PHP unless you spend time building it. Would you not get transparent scalability by adding Apache servers to the front end that just have the same PHP scripts? As far as scaling backend Postgres Database, that's the same if you use PHP or Zope.

Re: [Zope-dev] PHP vs Zope cost benefit
Dirk, One more quick question about application/business logic in one place and layout in another. Looking at ZPT, I still see expressions and condition statements in the Templates themselves. That's not really separation, it's just making it work with HTML editing tools. I'm curious is anyone can explain the true separation of business logic and presentation a bit better that exists with Zope now. I've built quite a few DTML heavy apps, and that separation wasn't there.

Re: [Zope-dev] PHP vs Zope cost benefit
To everyone who replied to this thread, I give a hearty congratulatory Thank you. They have decided to allow me to mock up the app in Zope and prove it's worthiness. I'm already halfway done with the first 2 modules. ;-) To recap what turned the tides were these wins: 1. Zope's security model is far more scalable and flexible than anything home brewed in PHP. 2. The scurity model is also audited by any, many people and tested and in production all over the place. ;-) 3. The ease of management for non-technical users to create and edit content was a big win since that interface is already created and ready to use in many cases. 4. The built in separation of db connectivity/transparancy is much better than taking the time to design that properly from scratch, or using connectivity tools that then needed to be 'connected' to the app in a safe and transparant way. 5. The transactional nature of Zope (although they didn't believe me when it came to rolling back multiple dbs) impressed them and if it really can mange a rollback from from a DB and transaction safety for inventory,etc...(which I know it can) then its a huge win. Thanks again to all who responded and put on their thinking caps to help be start another project using my favorite web app of all time. Thanks, Zopistas!

[Zope-dev] Tyring to FTP to Zope running behind firewall, get login box but no directory listing
It would appear that their FTP implementation is not working correctly, when connecting to a Zope FTP system behind a firewall. Zope is running on port 8880 and ftp service works fine from inside the firewall on port 8821. From outside the firewall, I get a login prompt, enter my password, but then the directory listing never materializes. Since I get the login prompt, it's not a firewall packet issue. Is this a known issue?

Would you also be willing to share some statistics on how many objects
you have in how many indexes, and how much time "complex" searches
take? I do understand if this is not possible, but it'd be appetiated
if it was possible. :-)
Thanks.
Well, here's the some output of the "Status" tab in the Catalog.
Subtransactions are Disabled
Subtransactions
-
Index Status
* 48205 object are indexed in bobobase_modification_time
* 48205 object are indexed in calendar_date
* 48205 object are indexed in calendar_day
* 48205 object are indexed in call_date
* 48205 object are indexed in curators
* 48205 object are indexed in data
* 48205 object are indexed in id
* 48205 object are indexed in meta_type
* 48205 object are indexed in resume_in
* 48205 object are indexed in status
* 48205 object are indexed in users_calendar
The only TextIndex is the 'data' index though. It is the one that gets
hammered.
Let's see...time stats...hmmm
I put a REQUEST.set with the ZopeTime at the top of the search page and at
the bottom after the 'in' tag for the Catalog.
Search terms are: los and angeles and C++ and MFC and 310
Subtracting the float of the two times I get 1.85400104523 I'm not sure
what that comes out to, I think it's part of a day though because of
DateTime.
The server stats:
Dual Intel 400mhz Xenon w/ 1MB cache each
LVD RAID 5 7200 RPM disk array
1GB RAM
RedHat Linux 6.1 with some kernel updates...
And the best piece of open source software I know: Zope 2.2.4 binary
release
Hope that helps.

[Zope-dev] Hacking Splitter.c
Hello, I have been hard at work implementing version 2.0 of our Zope based CRM software. I need a bit of help figuring out Splitter.c (lib/python/SearchIndex/Splitter.c) I have commented out both the parts that don't index numbers and single letter words. The numbers seem to be indexing fine, but the single letter words are not. :( My goal is to be able to find 'C' and 'C++' in a TextIndex search. Can anyone tell me why '+' doesn't get indexed, and where to change that? 'C' isn't in the Lexicon stop words, and neither is the '+'. Thanks in advance.

[Zope-dev] Performance enhancements, ZCatalog
ZCatalog enthusiasts, I just upgraded our zope installation from 2.1.6 to 2.2.4, and the ZCatalog performance is aweful. Can someone remind me what the command for speeding up python on a dual processor machine is? python -T? I'm looking for any way to speed this up. I have a text index with 47,000 objects and a search takes about 15-18 seconds, hardly what we were used to. It used to be 2 second tops.

How can I get 3 levels of recursion. I tried using 'let' to stand for the object, with no luck. That's the just penalty for writing weird code ;-) Actually, that's the penalty for using DTML. There's a difference. When you would introduce names for destination folder and id, you could use the same pattern for *all* levels. I don't understand what you are getting at here. You and other persons would understand what you do and you would not accidentally use the attribute "_". I personally, don't like using the "_" attribute at all.

Does anyone have a "object creation/folder distribution" code that works for them that they would be willing to share?

[Zope] Fighting htmllib in external method

[Zope] Disadvantages of using DTML (fwd)
Andy,
I am actually just starting working with it. As long as I can have help
futzing with the aq_parent stuff to get it to work, I'll be using it in my
intranet app.
My real desire is to find a way to construct these type of html objects
from html. Like a poor man's HyperDOM. :)
Cool, do I see a Zope product coming up?

Andy:
Actually, I have been playing with it.
What it does is create HTML, XHTML, XML from python objects like so:
p = TABLE(bgcolor="#0", border="0", cellpadding="1",
TR(
TD('my stuff goes here')))
print p
TABLE bgcolor="#0" border="0" cellpadding="1"
TR
TDmy stuff goes here/TD/TR/TABLE
So I just create bit and pieces that get called to form a UI.
Aquisition works too. I have a property in a containing folder, that I
called as the bgcolor of the table and it worked fine.
All my best,
The docs I quickly looked at suggested it just parsed XHTML into HTML,
nothing more. It would be interesting useful if it did do so much
more... Im
assuming there would be a little bit of Zope integration to do...

You may look at URL:http://www.dieter.handshake.de/pyprojects/zope/CatalogSupport.html It does the same as you want to do, but without the "formatter". Alternatively, you may try a "StringIO" instance as a file object. That's what I ended up doing. Finally, I can use files in external methods. You should, however, be careful as several threads can execute the same external method concurrently. Therefore, your files are better not global. That's what I was thinking.

I'm not sure if it is worthy of putting up on Zope.
Although I'm sure people will correct me if I am wrong.
But I have no problems in letting you have it
packDb.py is the main python script.
You will need to change the line that reads
s=xmlrpclib.Server('http://myserver:8080/', transport=None,
username='username', password='password')
To reflect your correct server details.
xmlrpclib.py xmlrpc Library for python.
Place this in your python/libs directory, or the same directory as
packDb.py
packExtension.py This contains the code for the external Method.
Place this in your zope/Extensions directory. Create it if it doesn't
exist.
You will need to add an external method to the root of your ZODB that points
to packExtensions.py script
If you have any problem then please let me know.

I may be wrong, but I suspect you may have made a similar mistake to most people who encounter XML. XML is not a whole data format, in much the same way as TCP is not a whole protocol. HTTP is a protocol that uses TCP, just as XHTML and DocBook are data formats that use XML. XML allows any XML compliant parser to PARSE the contents, but not neccesarily COMPREHEND it. So, a custom XML client could be built which would understand whatever I sent it, and display the desktop accordingly. However, an 'off the shelf' XML 'client'... who could say.

Re: [Zope-dev] Request for comments: Directory storage
Petru Paler: This is the embodiment of my MutliFileStorage thingy on Jim's ZODB Wiki. I droped it (Never picked it up) when Mountable Storage was announced. I'll create a ReierFS partition some time this week and try it out. Excellent! Hello all, You probably saw my yesterday post with the first alpha of ReiserStorage. One of the questions that people tend to ask about it is wheter they can use it without reiserfs. There are two problems with not using reiserfs: 1. ReiserStorage (now renamed to DirectoryStorage) stores each object in a separate file and *all* the files in a single directory. This was done in order to let the filesystem what it was meant to do: store and retrieve files quickly. While reiserfs is *extremely* good at this (it uses a btree to store directory entries), most other filesystems do linear searches when finding a file so performance is very bad when you have many files in a single directory. This problem can be solved by splitting files into multiple directories when not using reiserfs. This would add a little overhead but it is tolerable. 2. Waste of space. Typical block-allocation filesystems like ext2 and FAT will waste alot of space in the usage pattern of DirectoryStorage. ReiserFS packs small files together in the btree, so it solves the problem, but I have no ideea how this could be fixed easyly on the other fs's. Comments ? Suggestions ? PS: a new DirectoryStorage release will be done today, with bugfixes and new features. -Petru ___ 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 ) Jason Spisak CIO HireTechs.com 6151 West Century Boulevard Suite 900 Los Angeles, CA 90045 P. 310.665.3444 F. 310.665.3544 Under US Code Title 47, Sec.227(b)(1)(C), Sec.227(a)(2)(B) This email address may not be added to any commercial mail list with out my permission.

Thanks for replying Kevin, but it won't work ;-( I tried it ALL, and it
_will_not_work_. The nested ZClasses will apparently solve it (I used it
elsewhere), but it will get you into trouble in other situations - if
you want to add an instance of the nested zclass to an existing instance
of that same nested zclass. I had to change my product before because of
that.
I'm using nested ZClasses in KM|Net News. Take a look at the AddArticle
method. In KMNN, these ZClasses are set up as nested ZClasses, so that may
change things somewhat. However, it may still work. Rather than doing
manage_addProduct[], you *might* be able to just directly call
ZClass_add(_.None, _), because it could be in your acquisition path at the
top of the product. In KMNN, that's all I had to do, but in that case the
ZClass_add method was located within the ZClass that was to contain it.
That sounded kind of rambling, so I hope it makes sense...
No matter if you use ZClass_add directly or in dtml-with. No matter if
you close the first dtml-with and open another. No matter if you
redirect to get out of namespace problems (that will _really_ give
strange errors). Believe me, it was a _very_ frustrating experience (and
I really wanted to refrain from ranting -just couldn't help myself)
thanks again for replying

But: whats the reason for this? i simply have no idea (logs didnt show anything relevant as far as i understand). why i thought uups, was because of the same time this happend to me as to you (you also use 2.1.4). could it be a problem with 2.1.4? should we consider to upgrade to 2.1.6?

[Zope-dev] RE: Memory issue 2.1.1 wrap up (Long)
Thanks to everyone who gave me advise on what was going on. I think the problem was that I need some tuning in a variety of areas. (One of them being my brain) I am going to write up a little ditty on what I discovered so that people can check it before they claim leakage is occuring. I don't know enough about OS's to really put the *technical* explanations of some of the things to look for so, Matt, if you'd take a look at it when I post the url, I'd appreciate it. Just a quick rehash-- 1. I was running on an SMP machine, andthe setcheckinterval in Python wasn't helping me realize the machine's potential. This contributed to the slow down. Points:(2 physical, 1 psychological) 2. The 'Cache' tab in Zope was set to give objects a long, leisurely time in memory. This was causing Zope to rapidly claim and hold onto a ton of memory for objects it wan't even using. I adjusted it to 3 seconds. I worked the number until I found a happy medium. (BTW, I didn't really know *exactly* what this meant, and I hope there's a help system file on it in 2.2) Points:(1 physical, 1 psychological) 3. The 'Cache tab in Zope was set to allow a large amount of objects (20,000) to be a target size. This made those large amounts of objects that were lying around just happy to be there, I guess, I'm stil not sure what it does exaclty. Points:(1 physical, 1 psychological) 4. I store ton of information in my ZCatalog. The way the ZCatalog does an update (from what Shane told me) is a memory intensive task, loading lots of objects (I'd love help here), and when you combine that with 2 3, you get maxed out pretty quick. Catalog updates were taking a long time. Points:(2 physical, 2 psychological) 5. I use the standard Folder object to store 12,000 objects. Whenever a new object is added there is a huge hit on performance. Also, that object just so happens to get ZCataloged! That's turns Zope into a dog for a bit. [A good solution here is ZPatterns' RackMountable, but this is a production environment, and I want to let ZPatterns stabilize a bit. I am very excited about it though.;)] Points:(2 physical, 2 psychological) 6. The 'free' command on GNU/Linux shows just how much Linux buffers. A ton. Linux basically took my box from 1 gig of memory down to 1 MB, everytime. And that's is where it likes to stay. That's scary, but not fatal. Then the swap increased to about 40MB. When staying right on top of those numbers, it looks pretty bad while it's happening, so I believed things were headed down the drain. Zope's performance was poor (due to 1,2,3,4,5), so I thought the end was near. "If I don't restart Zope, things will only get worse." This is not true, the swap has hovered at 12MB average, and the free mem is averaging 4MB bobbing like a rubber duck. Points:(1 physical, 4 psychological) 7. There is in fact a memory leak in the SQLSession product. ;) Points:(0 physical, 2 psychological) All of these together with the fact that I learn more everyday about Zope and Linux, and you have the prime situation for Memorious Falsis. A syndrome where the hacker sees memory leaks that aren't there.

I just talked to Amos and Michel last Friday about that and they researched for a long time, whether it would be better to document the source or to have different files. They both decided it is the best to have the documentation separately. I believe that they looked at the issue from all angles and had good reasons, why they went with the current way. I trust them implicitly. I'm sure that my gut reaction was probably the same one they had, but after careful thought they found a better solution. Furthermore, the help system will become even more than just the screen help. The .py files you see, are just the start of the new API documentation. Oooo. Furthermore, we will include a new DTML reference soon. Do you know about anything else, that should be included?

The next task after the 2.2 release is that we will look through the tutorial and see what it does not cover and then add the missing examples in tutorial form. :) Off-site links are okay, but what happens, if I sit in the plane and I need that piece. Amos leans also towards external links I think, but I would rather keep it in the distribution; it is only a couple thousand bytes more and will not increase the distro size too much. A fact is, that most of the Zope Online Help should be the most up-to-date, meaning that we try to encourage developers to update and patch the help system as they update the code. Personally, I see that same thing might happen that happened to Zope. They'll want to get the product out badly, and since the help system is separate, they'll put it off. Our goal is basically to initialize a good, well organized Zope help system, which content is maintained by the developers, read community. I think this is terrific shot at offering everyone a chance to "get it". BTW, if you find any mistakes or want to make additions to the help texts, please send them to me. I hope I will be able to upload a complete revision of *all* the help screens by the end of the week. I have only 80 documents to go. :) Excellent. I am reading it.

Re: [Zope-dev] DateTime objects's and ZCatalog

Jason Spisak wrote: After minimizing your in-memory cache, look at the manage_debug screen again. Are the refcounts still high? I bet they are... No. The ref counts drop to hundreds. That's a big relief. Okay, now we know that this isn't a memory leak, it's only related to the fact that your site requires ZODB to load a very large number of objects into memory in order to perform normal operations. Here's something to think about: whenever an object is added to or removed from a folder, all objects in all neighboring folders and below are traversed. The manage_beforeDelete and manage_afterAdd hooks are called on each object. I am hoping to use ZPatterns to stem this rapidly out of control, ObjectManger not scalable, issue. Also, there is still the issue that Python doesn't seem to be releasing memory back to the system. I wonder whether that capability has been implemented in Python. It would really put a damper on things if is wasn't. However, when I stopped my Zope process each time, it didn't seem to give me back what Ihad started with. Maybe there is a leak in the kernel I am using. It's 2.2.12-smp. Anyone? Also, is see reference to 161 Products.GadflyDA.gadfly.kjparser.ParseRule, and I'm not even useing Gadfly! What the heck is that about? Anyone? Chances are some other product is "reaching in" to Gadfly. Do you have the Zope tutorial installed? It uses Gadfly. No. This is a Data.fs that came from Zope 1.
