I'm not sure that jinja2 and similar are really better for readability or separation of concerns versus TAL, and if some folks don't like TAL for DOM/XML/HTML-ish output, I'm left scratching my head why push templating like meld3 hasn't really taken off. My sense is that ZPT will continue to have its niche outside of Zope, but mostly confined to developers working in Pyramid development.

[Zope] IPublishTraverse adapters and permissions
I've been scratching my head on this one, any help is appreciated: I've been using a traversal adapter implementing IPublishTraverse with an application I am developing, and I want to have certain behaviors of my traversal adapter protected by CMF permissions I'm otherwise using. Right now, my adapter is registered in ZCML: adapter for=sdut.cportal.interfaces.IPortalMediaAsset zope.publisher.interfaces.http.IHTTPRequest provides=zope.publisher.interfaces.IPublishTraverse factory=.editvia.AssetTraverser / And my AssetTraverser subclasses Acquisition.Explicit, but I'm not sure how to make this participate in the security machinery. Ideally I want to do this within AssetTraverser.publishTraverse(): sec = getSecurityManager() sec.checkPermission(CMFCore.permissions.ModifyPortalContent, self.context) But this will fail, likely for some acquisition voodoo I'm having trouble figuring out (Five.BrowserView is somehow capable of dealing with this scenario, but I'm not sure how to make my traversal adapter do the same sort of thing). Or, even more simply, I would love to be able to use ClassSecurityInfo.declareProtected(permission, name) for some names my traversal adapter will use (this does not do anything meaningful other than generate warnings).

I'm supposing you are doing python package and Zope2 Product development, and in this case you definitely want each developer to have their own checkout(s) of code as a working copy on their own workstation or personal space on a shared server. It is likely you want to use separate databases (Data.fs) files for development (and periodically keep them in sync by copying a packed copy of the database from a central place). If you wish to use a shared database late in development, you can use ZEO or Relstorage to host the database over the network and have each developer workstation connect to that. I would not recommend a shared database for early development on any project, just for late-stage development and testing. Witch parts of zope/plone can I put on it? If you are developing on top of Zope and Plone, you likely do not need either of these in svn/git, just your own Python code packages. With svn you can alternately create bundle checkouts of your own modules and products interspersed with checkouts from svn of third-party modules you are using. You would only version-control code, not content in the database. I would like to use a control version manager but I have no idea how to configure my space, witch files can I control and so on see above. In a ruby on rails scenario I create the RoR project and a database then I create a git repository and begin to work (some commits here) Then if some other members join to the project I make a checkout from the master repository and begins to work all with the same database You can do this, if you want; see above. Again, I recommend against a shared database early in development; there is more that can go weird in ZODB than in ActiveRecord fronted RDBMS on a shared copy in early development. But I zope/plone I can't figure out what files I put to the repository and what happens with data.fs (some modifications are made in the database, what happend with them? I suppose I can't control them with subversion/git) You do not want to fork zope or Plone, but develop your own packages on top of them. That should make this easy, only modify your own code, unless you absolutely know what you are doing. There are other ways to modify behavior of other Products and the platform (monkey patching, subclassing existing components, writing new skins, creating generic setup profiles). Stuff in the database is not in svn; do not put code in the ZODB (e.g. templates edited through-the-web, though this is possible in some cases with some Plone skin code). Keep code on the filesystem. Content is not versioned in svn, if you need revisions of content objects in the database stored in a CMS like Plone, there are other mechanisms for that (e.g. CMFEditions is part of Plone 3.x). I hope this helps.

[Zope] zope.schema: association vs. containment in Object, List
All, I want to be able to spell out certain zope.schema.Object fields in my interfaces as contained while other fields are declared as associated/related objects. I'm interested in describing this in the interface itself, and not leave such intrinsic characteristics to the implementation class. It is useful, in my experience to have the ability for utility components to know this about a field (for example, relational database deletion cascades, JSON serialization of an object and its contained objects, neglecting related objects, or you might end up serializing the entire graph). Are there any community best practices for doing this? My previous attempts at doing this have been to subclass List and Object for OneToMany and OneToOne field types respectively, and treat original Object and List(value_type=Object()) fields as always implying containment. Is this reasonable? Are there other or better approaches?

My application (and I suspect other cases will) need to do just this; a marker on the field eliminates the ambiguity. Schema and interfaces should allow for complete domain modeling in such a way that expresses intent of the business case, regardless of the persistence mechanism or implementation details underneath, so I think I'll continue to use custom field types marked with an IRelationshipField interface, and assume the built-in Object, List fields are only used for containment. The only thing I do not like about my direction is that it leaves ambiguity when working with code from other components/projects that do not share this assumption. For RDBMS persistence of schema-defined content, z3c.dobbin (for example) assumes Object fields are just foreign-key relationships, but the downside to this simplification is an inability to meaningfully interact with a simple persisted containment scenario (a complex object that has contained specialized child objects intrinsically part of the primary object; trying to serialize to JSON with clear recursion boundaries for example, would be difficult). In my application-case, I'm looking to do something similar, but hoping to do so with a clear bright-line between associations and containment. Note: removal of such ambiguity is helpful for the possible use case of schema/interface bootstrapping/generation from UML tools for model-driven-design.

RE: [Zope-dev] BTreeFolder2.objectIds() - accessing _tree.keys() slow
Hacking objectIds() as follows (diff against trunk pasted inline) -
gettting ids off of the meta type index for all used meta types -
seems to make things much quicker. Two questions:
Are you sure this actually works? _mt_index.keys() is
supposed to provide a list of all meta_types used in the
folder. To get the object ids from it, you'd need something
like this:
ids = []
for d in self._mt_index.values():
ids.extend(d.keys())
The structure of _mt_index is documented in a comment:
_mt_index = None # OOBTree: { meta_type - OIBTree: {
id - 1 } }
I'm pretty sure this works. The in each OIBTree in _mt_index, the keys are
ids of contained objects for all respective meta types in the folder - I use
self._mt_index.keys() to list all meta_types and leverage your original code
that runs when spec parameter has been passed gets run every time - loops
through all meta_types does a union() of set and ids for each meta_type.
This returns the equivalent of running
self.objectIds(spec=self._mt_index.keys()) on the current trunk/release
code, which should be identical to self._tree.keys(), but much, much faster.
I'm still somewhat ignorant as to why self._tree.keys() is so slow with
100k-plus objects (waking up too many persistent objects?), but using the
ids stored a few layers deep in the _mt_index seems a viable alternative
with the same expected return result.
With a bit more effort put in, the diff pasted below should be more complete
and illustrate better:

[Zope-dev] RE: [Zope] Time module in python scripts
I hope you all don't mind, but I've moved this to Zope-dev. I would like to propose that it be possible without modification (default behavior) in a future version of Zope to import the time module and its methods safely into TTW Python Scripts. I haven't used this yet in TTW code (I've had to work around it), but it seems like it might be good to un-restrict it, especially for CMF installations that heavily utilize date metadata. time.localtime(time.time()) is, AFAICT, the only way to determine if you are in standard or DST at any point in time during the year. You can't have a page-template appropriately display correct times for content from multiple time-zones without this (I'm sure many CMF installations will need this), and it seems silly to write an external method for this; allowing import of the time module is a good workaround, but I would suggest it be enabled by default in Zope. My particular use-case is AP newswire stories which are in EST/EDT. The timezone offset changes for this twice a year, and having a fixed calculation based upon some assumption of a fixed timezone offset in my own timezone (PST/PDT) won't work. I need to be able to know my own timezone offset to do the math, and for this I need to use time.localtime(time.time())[8] to get it. I'm sure community sites and things like blogs, or anything else that works across the geographic boundaries of differing time zones could use this too. Thoughts?

This obviously doesn't solve security concerns for things like virus/worm/script issues, but I would think that on Windows, if you have that problem, this is the least of your concerns (since there is likely another way a script could attack your underlying storage).

RE: [Zope-dev] PathIndex doesn't index last part of path
I'm all for putting together a proposal to do this, soliciting comments, and
contributing to the effort. What would be the right venue for that?
On the other hand, AFAIK, the addition of a depth query feature to PathIndex
as it is wouldn't likely break existing indexes. And given that Andy's need
(get metadata for a Cataloged object, given some cached referecne, in this
case a path, to it) could be filled by the Catalog itself (or changes to
it), I'm not sure what other features would be needed out of PathIndex?
In brief, what I would like:
results = Catalog.searchResults(path={'query':myContainersPath,
'depth':0, 'level':0})
Where depth means:
-1 In parent of path specified (up one)
0 Contained within path specified
1 Contained in path specified or directly in one of its
children
2 Same as above, but also in child container's child
No depth specified means behavior is like current functionality in path
indexes. A brief glance at docs and code gives me the impression that this
could peacefuly co-exist with level.

the

within a hierarchy, there needs to be a simple mechanism to support query

RE: [Zope-dev] PathIndex doesn't index last part of path
If the question is begged, why use the catalog: for folders with thousands of objects, applications like CMF skins can be amazingly slow using ObjectManager methods and CMF-wrapped equivalents; they also do not provide sorting. For applications like this, both containment and flexible query support (sorting) are important. Use-case: thousands of objects in a Portal Folder. CMF Skins like Plone use ObjectManager based methods to get a list of siblings in a sidebar. When you have 1000+ items in the folder, the fact that this takes 2 minutes on an Athlon 2000+/1GB server, isn't batchable, and isn't sortable is sort of sad. Use of the Catalog makes much more sense here (I can sort, and the performance penalty is low, so I can take a slice of the resulting sequence of brains, and do getObject() over each one; even if a container could be improved performance wise to have a quick objectIds() method, ObjectManager interfaces have no mechanism to specify sorting based on metadata like you could do with a Catalog query). One thing that seems to be feature-broken about PathIndexes, though, is the lack of ability to specify a depth (not level, but depth of a match, for example, to specify items). Above and beyond support for a specific place within a hierarchy, there needs to be a simple mechanism to support query for an absolute path, and only objects directly matching that path, or directly contained within that path. The workaround for this is to add a custom FieldIndex that indexes the string value of the path of the items container, and this requires putting a python script in the root of a CMF portal, for example, that is acquired by all indexed content. It would be nice if the PathIndex machinery could do this out of the box. http://lists.zope.org/pipermail/zope-cmf/2002-August/014167.html http://lists.zope.org/pipermail/zope-cmf/2002-August/014204.html Sean -Original Message- From: Casey Duncan [mailto:[EMAIL PROTECTED]] Sent: Friday, August 16, 2002 4:55 PM To: Andy McKay; [EMAIL PROTECTED] Subject: Re: [Zope-dev] PathIndex doesn't index last part of path A PathIndex is designed to make it more efficient to aggregate objects at various levels of containment. Their primary use case AFAIK is to allow to to limit queries to particular places within a hierarchy. The idea is to eliminate recursive searching of leaf level folders when you want all objects under a higher level and its child levels. Also, by not indexing the nodes themselves, the index is an order of magnitude smaller and searches are therefore faster and it takes less room and is faster to update. In fact there is no need to index the entire path of an object in the catalog. Even with no Indexes defined, ZCatalog already does this for you. The uid of every entry in the catalog is the full path to the object (as a string). Unfortunately, ZCatalog does not expose this to the surface but you can write a trivial external method to do it. And I might entertain adding a ZCatalog API to do so if I had a good use case. Right now you can only access entries by RID. Now that begs the question, If you already know the path to the object you are looking for, why are you using the Catalog in the first place? I highly doubt doing what you describe below is faster than just directly accessing the object. In fact I'd be willing to be its slower, especially since you are searching two indexes to get it. Unless of course these are dynamically generated objects of some kind (no stored in Zope). As for making RIDs more permanent, that would basically require a rewrite of the Catalog, and make certain operations much more expensive.

This bug bit me today and is documented here: http://collector.zope.org/Zope/449/ISSUE_TRANSCRIPT/view I dont understand the brief argument against this one, it would make sense to me to able to pull an object out of the catalog based on its path. For example if I want /foo/bar/blammo, currently this means there is only one way of pulling the an object of the catalog given this path. Thats to send (path='/foo/bar', id='blammo'), rather than (path='/foo/bar/blammo'). Why wouldnt we want it this way? One thing I have done is store a whole bunch of references to objects as selected by the user. These are essentially random objects and the quickest way is to pull them back out of the catalog.

UserSniffer. Currently an External Method, but has functionality that should be available OOTB to assist making those (horrors!) browser-dependent hacks. It has other uses, too, like explaining to clients that their browser is five years old and needs the free upgrade that is available. 2. Support for HTTP_X_FORWARDED_FOR. Many (most?) of us run zope behind Apache ProxyPass or Squid, and the Zope logs therefore save the ip address of the proxying machine rather than any semblance of where the client browser is.

TF ZMI, was: RE: [Zope-dev] Zope 2.6 and OrderedFolders
You know, the funny thing is that TF really accomplishes the goals of a ZMI/UI-improvement hack (unclutter a view of a folder to VISUALLY separate the software/content/presentation space) implemented, IMHO, in the wrong place. I would think there is another way that a Folder UI could be uncluttered without the magic of TF, and that is add translucency (items are there, but obscured from view) to the UI layer - that is, the ability to VISUALLY unclutter different users' views of objects in a folder via ZMI; views could be stored per user. For example, you could select ZSQL Methods and RDB connections in a folder to be hidden from everybody but the Database programmer; you could keep these and Python Scripts obscured from the view of a content person or presentation designer, etc. Well, they wouldn't be hidden, but visually 'compacted' and relegated to a small drop-down box at the bottom of the page to unclutter it... so the standard tabled object list wouldn't iterate over objectIds() or objectValues(), but instead a higher-level filter function. A complimentary filter function would render the 'hidden' objects as a sequence as well. __ZMI manage_main Now:__ ===\===\===\===\--- ZMI tabs % :::=== TP.NAME. .SZ. ..LM..

RE: [Zope-dev] PDF-specific Bug in the ZServer implementation??? Orjust strange behavoiur of IE?
Acrobat uses something called byte-serving, which is a pain to support sometimes on the server-side, because it essentially amounts to serving parts of a file up to a given byte offset; when Acrobat acts as an HTTP client, it requests the PDF file, and once it has enough of the top of the doc to get header info from the file, it is able to omit downloading the whole thing and request portions of the file between 2 byte offsets, which represent the start and end of a page, as part of the http request. Byte-serving, unfortunately is not implemented in all http servers (or is broken in some, i.e. Apache 1.3.14). I'm not sure what the story for ZServer is, but I am curious to find out if there have been any developments in this regard...

these results with OFS.Folder.Folder yet. I'm too lazy/busy to comparison test. - I'm relatively sure that, in my app, the text index BTrees in the Catalog are very 'bushy' (more so than normal) because I am indexing people's full names, and street addresses, which means there are less common words than indexing, say, an every-day document. - Also, I want to make it clear that if I had a data access API that needed more than simple information about my datasets (i.e. I was trying to do reporting on patterns, like CRM-ish types of applications), I would likely wrap a function around indexes done in the RDB, not in Catalog. My requires no reporting functionality, and thus really needs no indexes, other than for finding a record for customer service purposes and account validation purposes. The reason, however, that I chose ZCatalog was for full text indexing that I could control/hack/customize easily. My slightly uninformed belief now is that for big datasets or enterprise applications (whatever that means), I would use a hybrid set of (faster) indexes using the RDB's indexes where appropriate (heavily queried fields), and ZCatalog for TextIndexes (convenient). I'm sure inevitable improvements to ZCatalog (there seems to be community interest in such) will help here. - I wonder if directory-storage combined with ReiserFS might make for an interesting future ZODB choice for this sort of app. Sean = Sean Upton Senior Programmer/Analyst SignOnSanDiego.com The San Diego Union-Tribune 619.718.5241 [EMAIL PROTECTED] = ___ 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] ZCatalog
Personally, I am of the opinion that sending a Catalog raw queries is not
very useful for really powerful searching... hopefully this changes in the
future, but for now...
Since catalog doesn't have anything built-in that does this, other than
globbing vocabularies, you have to do this within your appliction. What you
want to do is hijack and rewrite user queries before sending them through a
catalog query... for example:
word = 'dancing'
newword = re.sub('ing$', '*', word)
#newword is now 'danc*' which
This would work with plural words as well, as long as you have a useful set
of patterns for word endings...
For alternate spellings, abbreviations, and synonyms you would need to
create lookup tables and indexed methods that took advantage of them for
text indexes. This works only for text indexes though...
In summary, use query rewrites for word endings and auto-wildcarding (the
work is done at search time)... and use methods that weight and translate
your text in your product code (the work is done at index time)...

RE: [Zope-dev] Searching
I think this could be done well at the application level, above the Catalog if done right, but one would have to have good synonym translation table specific to their application. I do this in an application using a TinyTable with translation information for abbreviations (i.e. VW printed in a classified auto ad gets expanded to Volkswagen, so people can search for both)... If there was any sort of thesaurus database of sorts available to your application, I suppose, in theory, one could do some synonym-oriented indexing, profided that you index a method that brute-force weights the real words by outputting them a greater factor of times than the synonym (i.e. index a method that outputs the original text 3 times and synonyms for the meaningful words (non-stop words) in that text perhaps once. This is not difficult from a development perspective, but involves having synonym data and deciding what words should be translated to their synonyms, and what ones should not. I think the real issue here is not having a database of synonyms - and, at that, you would have to have one for whatever language(s) you needed to support.

Subject: [Zope-dev] ZCatalog becoming empty when using Update in
conjunction with ZPatterns
Hi all
I had a ZCatalog with about 3500 DataSkin instances indexed. Then
I started to index instances of a regular ZClass as well. Then I
added another index, to catalog an additional property of this
ZClass, and hit Update Catalog.
When Zope returned from updating, there were no records in the
Catalog, though the Vocabulary was intact. I see that I cannot
search for the DataSkin metatypes using the Find Objects
ZCatalog tab: they don't show up in the Find objects of type
field. So perhaps this is why updating failed.
However, now the Catalog is not accepting any entries. I originally
did the cataloging using this kind of loop on all the classes I
wanted indexed::
ids = container.Roundup.Issues.defaultRack.getPersistentItemIDs()
for id in ids:
object = container.Roundup.Issues.defaultRack.getItem(id)
Catalog.catalog_object( object
, string.join( object.getPhysicalPath()
, '/'))
When I try to run that again, I still get There are no objects in
the Catalog. upon return. When I run it using a newly created catalog
('testCatalog') instead, it works fine.
Could anyone perhaps explain what's happening here?

Jean

[Zope-dev] Overriding base class method / CatalogAware mixin
I'm having the same problem described in: http://lists.zope.org/pipermail/zope-dev/1999-November/002427.html My class inherits from a few base classes including CatalogAware as a mixin; I'm trying to override a method in my core API superclass (which uses MySQLdb, and thus mx-DateTime), with a similar method that is compatible with Zope's DateTime; I got a TypeError that I think is due to ExtensionClass when trying to call the superclasses method, even with an instance of the subclass passed as the first variable.

(AFAIK) Client-side trojans, which can cause your browser to invisibly post a comment on a weblog, execute a financial transaction, or break into servers you maintain, are a major risk. I had put something about that theme at the client-side trojan wiki, put I'll repeat myself since you mentioned it ... Methinks the creators of the http/1.1 rfc were aware of the dangers we call client-side trojan and wrote the following: 9.1.1 Safe Methods Implementors should be aware that the software represents the user in their interactions over the Internet, and should be careful to allow the user to be aware of any actions they might take which may have an unexpected significance to themselves or others. In particular, the convention has been established that the GET and HEAD methods SHOULD NOT have the significance of taking an action other than retrieval. These methods ought to be considered safe. This allows user agents to represent other methods, such as POST, PUT and DELETE, in a special way, so that the user is made aware of the fact that a possibly unsafe action is being requested. Naturally, it is not possible to ensure that the server does not generate side-effects as a result of performing a GET request; in fact, some dynamic resources consider that a feature. The important distinction here is that the user did not request the side-effects, so therefore cannot be held accountable for them. Zope really should not accept GET requests to dangerous manage_* (or other) methods, that would ensure it's at least compliant with the spirit of that rfc. If the user decides to use a browser which allows javascript to auto-submit forms and stuff, it's his choice. I have a feeling that other ideas like checking referer etc. are bound to fail after one or two generations of new browsers. We should have in mind that the same people who will design these browsers already had the bright idea of implementing auto-submitting of hidden forms. PDV just yields information you might give out anyway. But maybe we could deal with it anyway by writing an error.log instead of sending the traceback to the browser. What do you think? I fear it would make working with zope harder for unexperienced users. When working with apache/perl on linux, I always had a tail -f /var/log/httpd/error.log running in a terminal, but if you're solely working on windows without using the power of cygwin or other tools, this might get tedious. What I would like to see is a error product which can be freely configured to show more or less details depending on its context (i.e. user/role etc.) and able to optionally write to a log file. I know this is a lot of work and has its technical problems, but it's a nice imagination. cheers, oliver ___ 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 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 )

obviously this is not the case. There are, indeed, default values in some

some properties are changed (code below) I am having problems. I wonder if
I call self[id].index_object() after self._setObject(id, ad) if that will do
the trick?

the wrong date ('2001/01/01') instead of today's date, even though the

2 - Text indexes only get a portion of their text stored in the metadata,
not all of it. The index in question is built from a class method in the

Appologies if you already know this.
CatalogAware will automatically reindex if an object is added,
deleted, or moved. However it does not automatically reindex if
properties are changed.
It sounds like your index might contain the default (initial) values
for these properties. Do you need to add a call to reindex_object()
after changing them from the defaults?

RE: [Zope] Problem : ZCatalog
Right, use a python method, with a regular expression, like:
import regsub
def stringchange(self):
"""
Accepts a string passed as self, modifies it
using a regex substitution, and returns modified
This example strips multiple spaces, puts in a single one
"""
result=regsub.gsub('[ \t][ \t]+', ' ', self)
return result
You could use regsub.sub to replace the first instance of a pattern in a
string, or regsub.gsub to do all. Look in /lib/python1.5/regsub.py to see
all the regular expression substitution functions avalable. The regex
syntax is pretty vanilla; (i.e. chapter 1 of the book _Mastering Regular
Expressions_ has enough detail to use regular expressions well enough in
python). There is also a split function in regsub.py that might be of use
here, using the '/' as the delimiter pattern; I think you would use it like
this:
mylist = regsub.split(self, '/')
You could then write your function to get a particular item, like city,
language, etc by obtaining the slices from mylist.
Good luck,
Sean

Well, my solution would be to create a python method that splits your

of cool features of the ZCatalog is that it can index objects methods.

RE: [Zope] Zope and Linux flavors
Perhaps another option (for those with a load-balanced server setup), use an intel 7170 (not cheap, but cool) load-balaning appliance, and use the loadbalancer as a router; the 7170 has the abilitiy to set rules for where it sends the load to based upon expression-matching in the URL. This means that you could intercept all "/manage*" URLs with the load balancer and direct them to a box that returns nothing but error pages. I haven't done this (I have a 7140, this model's lower-end sibling), but I have looked extensively at the docs for this, and it might be an option for the cash inclined. Other than that, this doesn't get you out of securing your boxes. I would recomend traditional security strategies (putting servers proxied behind a DMZ), and a box-by-box audit of services using a port scanner. Other than that, I can recommend one of two realistic strategies in dealing with Linux (I dont' claim to be a security expert though) - either: build the distro yourself (i.e. LFS, www.linuxfromscratch.org), and keep tabs on what services are running, as well as monitoring the lwn (www.lwn.net) security page every week, or... Commit to a particular distribution/vendor and get on their security mailing list post-haste. Apply all patches before putting the box out on the net at large. And keep the box patched. Also, monitoring lwn's security page or bugtaq isn't such a bad idea. If you have the time to invest in it, consider a network intrusion-detection system and tripwire to watch the filesystem changes on your boxes.

RE: [Zope] way to cleanup form input text?
Write an external method in python that uses regsub.sub or regsub.gsub
functions. This allows you to do regular expression substitutions.
regsub.sub does a replace on the first match only
regsub.gsub does a replace on all matches
Ex:
import regsub
def process_a_string(self):
"""Processes a string, where string is passed as self"""
result=regsub.gsub('[ \t][ \t]+', ' ', self)#Filters all
duplicate spaces and
return result #tabs down
to one space char
where somestring is our example attribute call this in dtml:
dtml-var expr="process_a_string(somestring)"
is somemethod is a method returning a string:
dtml-var expr="process_a_string(somemethod())"

Subject: [Zope] way to cleanup form input text?
Is there a simple way to clean up text that's input to HTML forms in Zope?
I have a situation where one of my users is copying text from her web
browser and pasting it into Zope.
I'm sure this is a common problem..
The input text ends up having runs of whitespace characters in it
that I'd like to prune down to one each..and I think it's also been
the source of some non-standard, unwanted characters that cause
problems if they end up getting into our database..
I'm sure someone else has encountered this problem before..what's the
best way to fix it? The string module doesn't seem to have what I
want.. (or at least I couldn't find it..) The worst problems seems
to be long strings of spaces or tabs that I'd like to turn into
single spaces..(each)
Thanks!

[Zope] Pub. Company trying to patent object publishing?
Hi folks, Not trying to hijack the list for a rant, but I thought this might be of interest to some folks. Belo, a media company that owns a variety of TV stations, newspapers, and online operations, looks to be trying to patent what looks to essentially be object publishing (in a similar sense that Zope has - content-neutral objects published to multiple media). The irony of this all is that I found this in an article on the Newspaper Assn. of America's web site; the article embraces open-standards (XML, industry standards, etc), in the news content industry, and the author of the story is Belo's CTO. It seems to really fly in the face of truly embracing open standards to patent such ideas (especially in-light of the fact that publishing wit XML really demands OO techniques in the first place); and I think that there is plenty of prior art in Zope. Supposing their patents are approved, could/would a company such as Belo start using legal tactics the second that a company or individual someone started developing an open-source product on the Zope platform that cut into the news-content vertical? Or if someone at a newspaper wanted to use Zope's object database for a data-store or content-neutral repository, would they be a target? The second to the last section of the article is what I refer to, at: http://www.digitaledge.org/monthly/2001_01/newlanguage.html I think Zope would be prior art. I'm curious to see what everyone else thinks. Sorry to bring up a non-technical question on a mostly technical-related list, but I think this is something that needs to be discussed...

RE: [Zope] Zope vs. java solutions : looking forward ?
Frankly, it is a lot easier to program in python; it is much more forgiving in a lot of senses. If your developers like the idea of Java because it is OO, have them consider python's strong abilities, and the fact that they will be working with a persistent object system / ODB that can make their OO code much more than a filter for relational datasets. That said, if your developers like java because it runs in a VM on several platforms, Zope is cross-platform, and I guess Zope could be considered similar to a JVM: a platform for running cross-platform code. I don't think Java is a wise direction for a small firm; at least in Zope, you can start off with simplicity, and graduate to bigger solutions without a huge investment in lots of developers in the future. What kind of site do you have? For e-commerce, you are going to have heavy use of relational databases, but for publishing articles, you might want to consider using the ODB, something you are not going to get with Java solutions... I use Zope with XMLDocument and custom ZClasses for content, and it is a lot easier to get things done quicker that way...

RE: [Zope] Tux Zope?
I have extensively looked over the documentation, and am in the midst of compiling for the first time on my PC. Haven't tried it already, though; my main reason, is that I operate most of my Linux servers on Sun hardware, and am waiting for the dust to settle on 2.4.0 before I start trying to work with Tux; Tux is (in theory) only tested for i386, thought I don't see any reason (offhand) it won't work on Linux/sparc (unless there are some endian issues I am not aware of with the kernel-space module). The main advantage to Tux is that it caches TCP checksums (for all the content it serves, I believe), reducing CPU load, which seems likes a good idea (especially if you have hardware - like Sun - where your CPU is a bigger bottleneck than the bus, I/O, etc). Anyway, as complicated as it sounds, I am going to be setting up some new servers that likely have a configuration that uses Tux on port 80 (serving images only), Apache on 8080 (serving static pages, and logging access), and ZServer on 9080. Tux would proxy to Apache, and once that was set up, I could set up an Apache mod_proxy connection to Zope using the ideas in the howtos. This way, I get fast serving of images and multimedia via Tux, a full Apache config, and Zope running with virtual hosts. Once I try this config, I will let everyone know how it works out. What I would really like to see is this: Images and multi-media that can be served by Tux, but managed by Zope, so that all content is managed, but serving the images and multi-media is really fast, and not reliant on the ODB. I thought I saw something about a product that is like OFS:File OFS:Image, but saves the files to the filesystem - that kind of thing might work for such a config.

[Zope] Caching/http-acceleration and proxying Zope-served content
I have a question, for anyone experienced in working with Zope and caching proxies: I'm setting up a load-balanced server farm that has nodes that will run Apache and proxy (via mod_proxy) to ZEO clients running ZServer. This farm is routed (both ways) through a layer 4 load-balancing appliance, and all these boxes (both nodes and the balancer) are sitting inside a DMZ with private IP addresses. The public world will access these servers via a firewall box running transparent proxy (actually, I guess, similar to squid's http_accel mode; the semantics here are a bit tricky, as it's more of a inverse trans-proxy). Between Apache and Zope, there would be several virtual hosts, and I'd be using the SiteAccess product. It gets a bit tricky in that I need to access several different virtual hosts inside the DMZ (one for the ZEO farm, and another for a dedicated CGI-based ad server on another box) via the proxy. A more detailed (ascii art) diagram of what I am trying to do, is at http://209.132.8.98/server_ascii_art.txt My question is this: does anybody have any thoughts on the merits of Squid (http accelerator mode) versus Apache/mod_proxy in terms of caching, virtual hosts, and the like when working with Zope sites? Any big pitfalls to this kind of setup with Zope sites? Also, somewhat related, is: if anybody knows if Squid can even handle multiple virtual hosts running on different boxes? Or is squid not suitable for an inverse-proxy running on the border of a DMZ containing more that a single host? I'd really appreciate anyone's thoughts. Once I get this thing working, I'll likely end up writing a howto regarding how I did it, as this seems like a useful setup for a high-volume, heterogeneous (not ideal, but reality), production media site running Zope (and other legacy CGI apps / static content as well)...

RE: [Zope] Caching/http-acceleration and proxying Zope-served con tent
Hmm. That's been my thought on squid as well, given its ground-up design for caching in the first place. My worry, though, is that with squid I lose support for virtual hosts on seperate boxes, because I need to support Zope, static content, and some legacy stuff running ColdFusion on an NT box. My impression is that Squid's http accelerator mode (inverse transparent proxy, or whatever you want to call it) is somewhat of an afterthought compared to the standard proxy use case. If it supports the ability to direct traffic based upon the virtual host address, then squid works - if not, I think I have to go the Apache route...

RE: [Zope] Advice on searching/indexing Word documents?
I really like the idea of extending OFS:File to support different file types, but what I would like to see is something that is format/filter/library agnostic. That is to say, that perhaps the way we ought to go about this is to create an API framework that upon upload filters the file with a specified filter for its mime-type. Perhaps creating a generic base class that implements a generic API for filtering a file, from which to extend by inheriting more specific classes for files of particular types or groups (fine grained to mime-type or grouped in category, eg. "Illustration"). Having such a generic framework would enable Zope to be an excellent platform for digital asset management; Suppose you had a class for all files for a particular purpose, and those files would always be of a partiaular set of mime-types, like Illustrator, PDf, or postscript. For example, if someone working at a newspaper creates a new file class instance called "DisplayAd," which is used for postscript files with embedded fonts, containing specific text, a filter set up as part of the extended class for DisplayAd file would detect the type of file, determine it was PDF, and filter out the text, and the face names of the embedded fonts. If the file was a PDF or an AI file, it would then run the appropriate filter. It might also be nice to have a extended class (inherited from file) that works for all types, and keeps some sort of configurable plugin registry of sorts, so that we can create plugin classes for specific mime-types, but only have to use one class for the objects themselves. This might be more practical. One thing that seems important: creating an API like this could allow us to write filter "plugins" in a variety of Zope supported configs, like completely in python, a python class extending a C shared library, something written in a combination of C/Lex, or the python-based plex scanner that was mentioned earlier - for that matter, even proprietary user-space binaries called via python code might be fair game... I really think that this idea has potential as a project, and would be willing to contribute.

RE: [Zope] Advice on searching/indexing Word documents?
Cool. I'll have to take a look at this. Does anyone know if there is any effort aimed at writing document filters for use with Zope? A lot of commercial products used for knowledge management (like NextPage LivePublish, some Intranet search engines, etc) already have features like this, and I would think that a project for document filters would be a good idea, if something like this doesn't already exist. Possible things that could be filtered for input: - The IPTC header data from a JPG/TIF image - comtains a few things like the caption (the same one that you can edit in photoshop) - This would be a good addition to various Image classes. - Office documents (word, excel, powerpoint, wordperfect, staroffice, etc) - PDF and Postscript documents - Illustration files (Illustrator, CorelDraw) The value of such filters to Zope for use in knowledge-management and digital asset management would be great; I'm wondering if anyone is working on anything like this?

RE: [Zope] Zope vs. Enhydra
I agree that people should only build what they need. The nice thing about Zope being open-source is that it evolves well to its communities use cases; I would argue that Zope-based solutions would adapt to user communities that are not a bunch of software engineers working for software companies. I used to work as a developer for an RD company and now work for a dot-com doing the same sort of work, but my priorities are very different. Zope, frankly, is a more pragmatic solution than committing to the Java platform for a variety of problems faced by those of us not working for software vendors, and I think is better suited to an open-source user community. Two particular things: One: Enhydra seems ideal if you have investment in the Java paradigm (i.e. you have Java coders in house). The thing is that Zope has a lot of strengths in the ODB that you can't get with your typical OO Java servelets combined with an RDBMS back-end. For complex relational data, the Java app server approach might make sense, but the thing that sells me on Zope is the fact that their are problem domains that are a total misfit with a relational data paradigm, like online content publishing (media sites), intranet collaboration (workflow objects associated with discussions associated with content created via content management) - not to mention the entire problem domain of XML in general. So, java app servers make sense if you meet all of the following criteria: - have data structures that are tabular, or have a small set of relations to other data - have a full-time DBA - have a full-time Testing Department (test manager, testers) and Formal Software Testing - have at least a senior Java programmer or two - Have a fairly technical project manager that understands how the app server works, in order to divide up work - Fully implement formal documentation standards, including UML, requirements design docs, and EXTENSIVE API documentation - willingness to work on a deadline that is not as tight, putting quality always before expediency In other words, java app servers might make perfect sense for those working in an RD company, ISV, or other vendor selling software, but it creates complexity when you want to extend this to an open development model because the learning curve is steeper, and it's easier to screw something up. If you work with limited resources, and are not building a product that is going to have an expected sale value, but rather only internal use value (i.e. you are a web company trying to get a site up versus a software company selling a $25,000 shrink-wrapped box). When in that position, you need content management built-in; you need portions (like the interface layer) to be as easy as possible (Why should one be required to compile an html file into a DOM binary - why not just use an ODB???); you also are not going to have a testing department, you will have a stricter deadline, have less technical project management, and no docs, and more employee retention problems. The attitude is get it done, with the best possible balance of doing it "right" and getting it up live. Zope fits the bill for most folks who have to work in a pragmatic world of building and constantly refining software for their own use. I'm not saying that we shouldn't have formal docs, testing, etc of software, but that some of us have to maximize quality under certain constraints that guarantee that the Java app server approach would be flawed; Zope fits (python is easy to work with, the presentation layer concepts in Zope are improving, etc). Zope also maps to open-source ideas better, because it allows for a less centralized formal development model, and the idea of constant refinement. In the future, especially in certain vertical markets (like mine, publishing), the folks that comprise your community will not be trained software engineers - they will be folks like librarians, part-time web developers, designers, project managers, and production engineers/sysadmins - and in that open source world, we need to be able to create scalable software systems, but not raise the barriers to entry to make them inhuman. Zope isn't perfect in this regard, but at least it's leaps and bounds better than the alternatives. Two: Perhaps the biggest gripe I have about the "why-not-zope" arguments is simply that they make the assumption that Zope is somehow a product, and so they complain about what it cannot do, rather than realize that zope's primary asset is a strong community and a strong, swift software process; I have seen Zope evolve quite rapidly over the last year-and-a-half; I use that as empirical evidence that Zope grows with its community member's use-cases. Gripes about things like through the web editing, cvs, etc will likely be things of the past in the not too distant future. I think Zope has some advantages over both other approaches in that it has an approach that

What kind of content is it that you are uploading to Zope, and what is your workflow? As someone working in the news industry with several online newspapers and also fairly experienced with Zope and content automation, I might be able to make some suggestions that might help you out. Zope has some weird issues with namespaces and syntax that sometimes clash with Python's. That said, I think that things are constantly improving. Perhaps _['identifier'] solves your problem, at the slight cost of being just a bit kludgy. Do you use Zope for your staging server, or just for your live site? There might be ways to use it at both ends, integrate with dreamweaver, and bypass using wget...

And even when relying page updating on trainned personnel exclusively, there's been this funny experience that the printed edition releases before the digital one, meaning that we have to deal with this gap between releases all the time.

Batch-replacing every "_html" with ".html" in file names and content seems to be very complicated within this scenario. Going from dreamweaver to Zope, if you are working on unix, batch replacing is EASY, a single find command to change the file names and a simple sed script (or python or perl) to change hrefs. You will need to write such a script anyway, if your servers are Unix or Linux and your Dreamweavers are Windows. You will find that your windows people mix filename case randomly and expect it to work; you will have to canonify all hrefs to a single case convention. If going from zope to dreamweaver, either write the corresponding _ to . scripts and batch it, or write a checkout external script that does it for you. I have not thought about this latter option very much, but the export facility should give you an example of how to do this.

RE: [Zope] site structure (fwd)
You may also want to take a look at HiperDOM as a templating mechanism as well. I haven't used it, but in looking at the Wiki and the examples, it looks like it would do what you are looking for, and from all accounts I have read, this will be the "official" Zope replacement for DTML for presentation logic in the future (relegating DTML for logic use, along with Perl and Python methods), and has a lot of cool features that allow you to create a template with mockup data that actually renders your presentation, replacing the mockup. http://www.zope.org/Members/lalo/HiperDom I'm working on a content-management project in which I am just starting to do real user interface work, and I am likely going to try switching over most of the presentation from DTML to HiperDOM.

RE: [Zope] site structure (fwd)
Getting fairly familiarized with namespaces and acquisition is going to be useful here. You actually will need to do 2 templates (one for the footer, and one for the header) in the case of writing a "wrapper." That said, objects in Zope (like a document, in this case) behave based upon their context or environment. A DTML document, when it is told to render something with dtml-var name="foo" looks for foo in it's current namespace (i.e. the folder it is in), and if it doesn't find it, it then works its way upward (by looking in the namespace of the folder that is the parent of the folder it just looked in before). When it finds foo, it renders that method (or if foo is an attribute, it renders its value). Let us suppose that your document is called bar, and looks like this: htmlbody dtml-var name="foo" /body/html bar is in a folder hierarchy that looks like this (using URL syntax) http://mysite.com/folder1/subfolder/bar bar would first look for foo as an attribute of it's own namespace (i.e. it would look to see if you defined a custom property called foo in the properties of the document). If it found it, it would render it, but let's suppose that it does not find it, so it has to look in another namespace. So, it moves up to the next namespace (subfolder) looking for foo, as either a method of that folder or a data member (attribute). If it finds it, it renders it. If not, it moves up to folder1 as the next namespace, and perhaps that is where it finds foo; in that case it renders foo. Seems rather simple, and in some cases it is, but what if foo is a dtml method and looks like the following? h1Title:dtml-var title/h1 Where does foo look for title? Not in folder1, where foo resides, but in in bar's namespace, and indeed, since dtml documents have a title attribute, that will be rendered. If, instead of title, we had an attribute named something like "what" but there was no attribute named "what" in bar, it would look through the namespace stack (starting with the namespaces of bar, then subfolder then folder1, then the root folder, etc), until it found what it was looking for. This, I hope, explains acquisition well. If you were to apply this to templating strategies, you would realize, that (as long as you kept standard_html_header and standard_html_footer in sync) that you could do some powerful things with your site navigation. Consider the following example: Suppose you have a sports news site, and you publish stories about baseball, football, and basketball. In the upper right hand-corner of your document (i.e. in the header portion) you have an 32x32 icon image that is a picture of a football, basketball, and baseball, respectively. Otherwise, you wanted to use the same template for all of the documents. Suppose that you have a folder structure like this: -/ -basketball -baseball -football In this case, you could have a standard_html_header in the root folder / that creates the top portion of your document, so you only have to use one template, and that the template might have code that looks like this: !--html here-- dtml-var name="sports-icon.gif" !--more html here-- In this case, you could have an image in each folder (basketball, football, baseball) containing an appropriate image with the id of sports-icon.gif. This is useful, because now, one template is rendering sports news stories different folders differently, depending upon the context of the folder they are contained in. In this simple example, you don't even need to create a different standard_html_header for every folder to create different results, but can rely upon Zope's built-in acquisition smarts to work for you. Applying this in practice, takes some playing around with, but once you get a clear idea of applying this, you can create some very intelligent standard_html_headers that do a lot of work for you.

RE: [Zope] HTML formatting from a text field
I remember reading somewhere about messaging between Java applets and JavaScript code in the browser, allowing JavaScript code from a web form to manipulate the applet output; the example was typing something into a text box, clicking a button in a form, and having that rendered in some obscure font inside the applet. Where I read this escapes me, and I've never tried this, but I wonder if such a trick works conversely. In other words, what if the applet can pass values to a JavaScript variable associated with the value of a form input element in the browser's HTML DOM? I could imagine that something like this could be very effective for certain situations where people want better through-the-web editing of code (imagine if you could edit dtml in a web form color coding syntax with a feature to collapse blocks of code, similar to Homesite 4.5, or editing python scripts -- what were python methods -- with an outline-based editor that created automatic indentation). Or, better yet, imagine running JPython within the applet (I don't know whether this is possible) to do all this. Anyway, I wonder if this type of thing could be an alternative to either ActiveX components or a XUL/XPCOM based-interface.

RE: [Zope] access log analyzer (analog, webalizer etc.)
You could use grep/sed, etc, and a some shell scripts (or perl or python scripts). Instead of sed and grep (and regexes, and inconsistent results, and a lot of manual work), what perhaps a lot of folks need is unified, aggregated logging that actually looks into Zope's architecture and uses mod_perl for static stuff and CGIs served in Apache. I've thought about this a bit, and it seems to me that many sites (at least bigger ones) often use a combination of technologies (as well as multi-node server farms) to serve up their site(s). As such, if you are running stuff served from Zope, Apache, CGI, other app servers, etc, you want a unified logging platform. Add to the complication HA/load-balanced/multi-server farms, and you want to be able to aggregate logs from all boxes on all server platforms to log to a unified system. The answer seems to me to be use of a relational database, mod_perl, and the example DBI Apache logger code in O'Reilly's _Writing Apache Modules_ with the following tweaks: 1 - Add persistence to the mod_perl DB connection with Apache::DBI 2 - Tweak the tables to add the following fields: box (server node number, for HA farms) mime-type user object_id (used, along with URL to determine what object is being used by X method) 3 - mime-types determined for Apache-served static pages with RegEx on URL 4 - Zope-served pages are excluded from Apache's logging, use ZSQL methods inside Zope to log (below) 5 - ZSQL method for logging is created. Logs the relevant stats to the relational database AUTHENTICATED_USER is logged to user, and dmtl-var id is logged to object_id - mime-type is the object's mime-type 6 - Insert dtml-call expr="mylogmethod()" into standard_html_header in top level (all acquired use of standard_html_header will log) 7 - Roll your own report-system using Zope, perhaps... I've already started working on something of this sort for a long-term project I have to implement logging for my company's new HA server farm. Such an approach might also be a good thing if one is using a ZEO setup. So far, I have set up the Apache side of things, logging to MySQL, and I am working on the Zope side of things. The real work, though is not in logging, but report generation, which would be a nice Zope product. Perhaps in a few months, I might have something worth showing... Any thoughts?
