[Zope-dev] Persistence ( was Thread Safe Counting )
Morten's product stores the counter's value in a file on the filesystem, and so it doesn't cause the Data.fs to grow. Hmmm, well, my counter above wouldn't cause the data.fs to grow all that much, since it subclasses Persistent and so gets its own pickle jar. cheers, Chris So subclassing persistent will avoid changes to the object being stored and roll-backable in the ZODB? Nice! Now, if only we could get this sort of store-in-place functionality on a more fine-grained level (like on individual properties) - we could avoid a lot of coding to prevent ZODB bloat with simple features.. Ie, if I were to make a 'persistent porperty' on a DTML method, I could store counter information in that property without worry of ZODB bloat.

[Zope-dev] manage_ methods
Nope! the method calling the manage_* method can have proxy roles setup for it so that it can call manage_* methods for users who do not have the capability to call that manage_* method. Also, any user can be assigned access to the manage_* methods needed on a particular document/method/object by giving them the rights do what you need to do, such as the Change Properties and Add properties rights (might also need the manage_properties right, but I dont think so) via the security tab inside Zope... did this help? Hi again, Is it true that you have to have the Manager role to use any methods that start with manage_? If so, that's pretty unhelpful, almost as unhelpful as the DocString limitation :-( cheers, Chris ___ 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: Re: [Zope-dev] ZSQL using LIKE operator
sqltest just creates the full string of the where clause segment for the test using the same kind of 'safe' sql-string logic as sqlvar: so you should be able to replace the value to test against with any valid python expression, such as the one below where the % operators are concatenated onto the variable holding the value you want to test against. :) As for the difference between dtml-sqlvar and dtml-var sqlquote (in case anyone is confused), an sqlvar tag requires a type value and will not only perform an sqlquote on the value being inserted into the statement, but will do any/all type conversion/stripping (letters from numeric values, etc) needed based upon the requested type. If anyone is concerned/puzzled by the security hazards I listed below, here is a URL describing problems associated with bad data used within queries and a mysql DB: http://www.mysql.com/doc/G/e/General_security.html See the bullet point beginning with 'Do not trust any data entered by your users.' Sorry if I seemed harsh in my original post, but security is my bread and butter, so I may tend to be Loud when I see something wrong... PS: In order to increase the safety of ZSQLMethods, maybe the basic dtml-var tag should be made illegal inside it?

[Zope-dev] Re: Zope server dies with Netscape's FTP
I think this may be a problem with passive/active FTP sessions and (possibly) proxies settign between you and the Zope instance. I've had the same problem with other FTP clients when I try to FTP into a Zope server: at one client's office they do NAT, which acts as a proxy - around 60% of the time my FTP session will lock up on a PUT, and the WHOLE zope instance dies. I had written it off as somethign to do with the clien'ts network - but if its happening to others out there too, then maybe its time we launched an investigation into this? The problem I noticed when I looked at it previously is that no error was ever logged, even with the debug option turned on - the zope instance just died mysteriously. Anyone know of a way off-hand to force zope to do a stack traceback to the error log when an FTP error (or some other unknown error) takes it down?

I noticed that 2.3 didn't update the quickstart materials, and that the quickstart materials still used the old server-side-include syntax internally and in their examples. To make matters worse, the ZSQL method examples didn't use sqlvar - thus were unsafe. I updated the complete quickstart to fix these problems and have sent a copy to Brian Lloyd for future use.

Re: [Zope-dev] Passing arguments to DTML Methods
This is an undocumented (afaik) feature of DTML methods/documents - due to
the way python
argument mapping works, you can pass any value into a 'local' variable in a
DTML method like thus:
dtml-var "myDTMLmethod(foo=5,greg=Sally)"
this the above case, Sally could be a legal variable value that will be put
into the new local greg
in your DTML method, and one named foo with the value of 5. AFAIK this is
pass-by-value, so modifying greg in your called method will not change
sally, but I could be wrong...
I use this sort of thing quite often in one of my ongoing projects where I
need to reformat
dates strings from their mysql format to how the client wants to view
them... I have a method named
undb_dateout that uses a variable called 'dbdate' and does some string
splitting and formatting to output it.
Originally, I would do things like this with the method:
dtml-call "REQUEST.set('dbdate', currentdatevar)"
dtml-var undb_dateout
Then, on a whim I changed this to:
dtml-var "undb_dateout(dbdate=currentdatevar)"
And it worked...
Someone should add this to the DTML documentation, or at least make it stand
out more - it is VERY
useful... If no one else does I'll write-up a how-to on it.

Sorry this, possibly, very trivial question:
How do you pass on variables to a DTML Method.
If I would use a python method I would use dtml-call "pythonmethod(var1,

how is it possible to get around the problem?

[Zope] Odd SQL errors- HELP
Hello, I have Zope 2.2.2 running with a MySQL database, and everything _was_ working fine until I started to play with the new database structure our dba came up with for tracking our recruiting process... anyway, i have a db named recruit, with a MySQLDA connection object to it that works, but on mnay of the tables I get an error such as the one pasted below when I attempt to do a simple query... Now, the state table does not return this error and has this structure: (as cut-n-pasted from the mysql monitor) +---+-+--+-+-+---+ | Field | Type| Null | Key | Default | Extra | +---+-+--+-+-+---+ | state | char(2) | | PRI | | | +---+-+--+-+-+---+ meanwhile any of our tables with 'id' fields choke with the keyerror: unhandled, heres an example table struct: +---+--+--+-+-++ | Field | Type | Null | Key | Default | Extra | +---+--+--+-+-++ | id| mediumint(8) | | PRI | 0 | auto_increment | | value | varchar(32) | | | || +---+--+--+-+-++ Now, at first i thought it was the field name of 'id' causing the problem, but now I've tried renaming the field and its still a no-go. I can do queries such as 'select value from reason' fine, but if i select * or the id field, it chokes... Looking through the mailinglist archives, I think its a 'mapping error' where the ZmySQLDA doesn't properly map this type of field for some reason... can someone help me solve this problem? Yes, I can change the db, but thats really not an acceptable option, since the dba will then just go 'Well, if zope cant handle a simple db structure without changing field name and/or types, then i refuse to sign off on using zope as a development tool!'

[Zope] Re: Adding a new property over http
Heres a snip of DTML that adds a property to the parent if the property
doesn't exist.
If you create a ZClass with this, it will modify the parent folder when
called from
within a DTML document, if you do it as a DTML Method, it will modify the
parent document.
dtml-if "hasProperty('z_count')"
dtml-call "REQUEST.set('z_count', z_count + 1)"
dtml-call "manage_changeProperties(REQUEST)"
dtml-else
dtml-call "manage_addProperty('z_count', 1, 'int' )"
/dtml-if
Now, if you wanted to Take a variable in a form (or link), and make it a
property like in your example, you're method would look like this, Assuming
the form had fields to pass the values as 'NewName:string' and
'NewValue:tokens', or your calling link ends with
?NewName:string=fooNewValue:tokens=mytokens
dtml-if "hasProperty(NewName)"
dtml-call "REQUEST.set(NewName, NewValue)"
dtml-call "manage_changePRoperties(REQUEST)"
dtml-else
dtml-call "manage_addProperty(NewName, NewValue)"
/dtml-if
I hope this helps! Now if only someone could answer why the behaivor
changes between having it as a DTML method and a ZClass! (And how to fix
it!)

Previously I made a DTML method that when used within a

Having this floating around in root made it visible to the

the DTML method into a ZClass, and making the index_html
method in the ZClass contain the exact same DTML as the
method... But it doesn't work. So, I tried again - this
time with as simple a method as possible, a very basic
counter. The DTML method I made in root increments and
displays the 'z_count' property on the page that calls it,
and creates the property if it doesn't exist, so using it
is as simple as:
dtml-var mycount
However, I place the DTML into a new class, and then make
a new instance of the class, and it wont work as above.
I now have to do this:
dtml-with MyZCCount
dtml-var MyZCCount
/dtml-with
And, instead of modifying the property of the calling document,
it modifies the parent folder's properties. Below is the DTML,
can someone please explain what I need to do to get this to
work on the calling DTML document instead? If I can't get
this simple counter to work I'm going to go mad, since changing
properties is something I need to be able to do from many of my

Re: [Zope-dev] patch for dtml-foo:bar:baz;
This may, or may not, break the alternate syntax patch/download @ http://www.zope.org/Members/Coventry/dtml_shortcut I'll investigate and find out, and release a new dtml_shortcut if needbe. (I specifically used a colon since it is valid xml) What about using a colon as the separator, but explicitly give the tag the name dtml-root? dtml-root foo:bar:childofbar having a whole tag of type ':' seems weird (in addition to possibly breaking current patches and such ;) if we didn't want the root to be the default we could use something like dtml-trans [path]:[path] with something like _root or __root being set aside as a special name for starting at the root (otherwise it would start in the current directory)...? This patch changes lib/python/DocumentTemplate/DT_HTML.py so that you can use paths for traversal in DTML entity syntax. The delimiter is ':', as it is valid as part of an XML entity, but not valid as part of a Zope object id. You can use dtml-:foo:bar; to ensure that traversal occurs from the root object. This patch is against Zope 2.2.1b1. It relies on the restrictedTraverse() api. A 2.1.x version would be possible, but would be rather messy. ___ 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] ANN: Border Aware Image Update for Zope 2.2.0
The Border Aware Image add-on has been updated for Zope 2.2.0 - installation has been heavily updated and is now much easier. see: http://www.zope.org/Members/Coventry/Border_aware_image Also, the alternate syntax patch/add-on has been tested with Zope 2.2.0 now, and no changes were needed. The new documentation reflects this at: http://www.zope.org/Members/Coventry/dtml_shortcut Also: I will be submitting a proposal soon to dev.zope.org: the project would handle evaluating and integrating small add-ons such as these and others into the Zope core, please email me if you would be interested in participating. ~ Jonathan M.

[Zope] two stupid, non-technical questions.
Please excuse these questions, they are not my average question fodder... A) Are there Zope t-shirts available, or downloadable artwork to make your own Zope t-shirts? - this question was actually posed by a co-worker who seems to get his entire wardrobe from copyleft and software companies promoting their products... would a copyleft shirt be appropo? B) Has anyone modified their apache installation (if using the apache pass through to Zope) to return the server as being a Zope server? I ask because if we do not do this, then we (the Zope community) will only appear in the netcraft server surveys when using the stand-alone ZServer... ___ 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 )

[Zope] Single content tree, 3 'look-n-feel's...
Hello, I'm currently preparing to build a large corporate website with Zope. the corporation in question ants a dell-ish sort of interface and content tree in which users will choose on the opening pages what Sort of user they are (home-user, small business, or corporate) - after choosing the type of user they are, the look-n-feel of the site will be geared towards their specific type, but, the content will be shared across all of the different styles. that is to say, I might have a products dtml document, but it will need to look different for each type of user. I know this can be done easily with some simple session variables and some logic in my standard_html_header and footer, but I was wondering if there was an easier (to manage - different people will be in charge of each look-in-feel) way...? I saw an announcement on "transparent" folders - would that be of any use in this situation? ___ 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] HTML Editors that recognize DTML (was bastardized formofXML)

RE: [Zope-dev] Confera fix

[Zope] possible security flaw? - and, request for a phone conference.
Hello, First off, sorry for the cross-posting of this message to admin and to development. I'm a software developer for a major ISP in the Midwest region of the USA. Recently we began evaluating Zope for use in our web application development, internally and for our clients, and have been quite pleased with the wealth of features and add-ons available*; However, I need two points addressed if possible: 1) We are running Zope 2.1.4 mapped to the root of the apache install on a Linux (mandrake 7.0) box, and have found a rather nasty security - or at least, its what I'll call a nasty problem - because if you don't know about it, it could really bite you in the butt. Basically, if a user with manager privileges to a folder changes their password to be empty, then anyone (from permitted domains) can access the management screen for that folder Without Logging On... Zope assumes that you are the user without the password and treats you as if you have those rights. I found this problem when one day the welcome Zope page (default from install) didn't prompt me for a password when I clicked to enter the management screen. I did not realize what had happened until I went under the 'undo' tab and saw that all of my actions while I was snooping around for the problem were being listed as being done by one of the other developers... I went into the acl_users and fixed their password and everything is back to normal. I've tested this by setting my own password to an empty string, and it lets me log in... From a security standpoint, It should probably prompt for a user name and password, and simply accept a empty field for the password As the password for that user... Anyway, my point is to either inform the community of the bug, if it isn't known, or to find out if it is known and has been fixed in the newest release... If it has not been fixed in the newest release, I will be glad to create and provide a patch... 2) As an experienced web developer, I'm very keen on new technologies that can be reused and make my life easier - thus Zope is a godsend. However, my management is hesitant to start using Zope on a regular basis for our projects - they feel it is unproven and possibly unstable: Now, I realize, and have informed them of the facts, that Digital Creations makes their living off of Zope, and that new businesses are springing up almost everyday that are Zope-centric, and that many contracting/development firms are embracing it whole heartedly... But, my management is still kind of hesitant. Is there anyone among you in the community who would be willing to write about your experience with Zope in the professional development arena, to address their concerns? Even better, Would anyone be willing to participate in a conference call q A session on Zope's suitability for use in professional web development? I cannot offer money for these, but I can promise my undying gratitude, and, I can promise that any and all add-ons and patches we create for Zope would be released back to the community at large... As a large website app dev firm, our contributions could be significant... Please email me privately if you wish to possibly participate in the phone conference. Thank you for your time and attention! * I have already made two modifications to the Zope source, one dealing with making 'border' a built in property (and used during tag output) of the image object. and another, simple hack to the basic dtml parsing routines that makes your dtml development a little faster by requiring less typing. Both of these will be available under my member area on Zope.org. Hopefully these will be the first of many patches and add-ons I get to contribute. ___ 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 )
