TreeTag Troubles
by love＠formylove.org 03 Aug '01

03 Aug '01

Greetings, I am working with the dtml-tree tag to display a list of folders with in a large directory. In the dtml method that the tree is displayed I display the documents and downloadable files below the tree for the selected folder. I need to be able to keep the full folder tree as it is on the base url on the subsequent child folder views for example the tree that is displayed on http://www.mysite.com/userdir/contents_listing_html needs to be the same on: http://www.mysite.com/userdir/Zope/contents_listing_html just with the current node expanded and maybe current folder name in bold print. The problem is I only want to display documents that are within the selected folder in a list below the tree, like Folders: <dtml-tree> Tree code for folders </dtml-tree> Documents: <UL> Code to get documents </UL> Does anyone know how to do this? I have already spent alot of time messing with it with alot of errors, so any help is appreciated.

RE: Use Homesite (was RE: [Zope] Great html-applet ( commercial ) ...)

HomeSite 4.5.2 == ColdFusion Studio 4.5.2 They are the same product but the Studio has all the Tags built-in for CFML. I installed the Studio once and then wondered why as the two looked exactly the same. How did you get the DTML tag completion? Have not tried that yet but would be nice. Maybe we could trade custom toolbars?

DTML meth makes Zope 2.4.0 core dump...
by Pierre-Julien Grizel 03 Aug '01

03 Aug '01

(BTW I forget in my previous post to precise I use 2.4.0 on FreeBSD). Here is a DTML Method : <dtml-in RESULTS> <dtml-let RESULT=sequence-item> <tr><dtml-var "CONVERTER('','')"> <dtml-in FIELDS> <td><dtml-var "CONVERTER('', '')"></td> </dtml-in> </tr> </dtml-let> </dtml-in> This method is called from a Python Script, and CONVERTER is a reference to another Python Script. The first <dtml-var "CONVERTER('','')"> works perfectly (the script is called and returns correctly), but the SECOND ONE makes Zope core dump. Urglhh... Can someone explain me this more than strange (and more than annoying) behaviour ? Thanks, Regards, P.-J. -- If the only tool you have is a hammer, you tend to see every problem as a nail.

Thanks, I'll take a look... I could always just give it a try and write some python code to dump garbage to a BIG file, and write some code using file seeks to move to large byte offsets... I'd definitely try it before I tried using it in Zope/ZEO...

Folder Navigation Not Working
by Rob Williams 03 Aug '01

03 Aug '01

I tried to follow the navigation example from the Zope Book that's online. I made a tree that looks like the following: root projects jobengine requirements specifications outbound When I'm in the projects folder, I see the folder below it (and the links work). When I go up to one of those folders, though, I don't see any of the subfolders at that level. Here is what I have in the footer (taken from the example verbatim): Projects:&nbsp <dtml-in expr="objectValues('Folder')"> *<a href="&dtml-absolute_url;"><dtml-var title_or_id></a> </dtml-in> At the second level I don't even get the asterisks so it's not finding anything. Each of the folders at the next level (requirments, specifications...) has an index_html DTML method in it. I thought it might be something with access control but there are no user folders in any of the sub sub folders. I'm discouraged that something taken right from the book doesn't work! Thanks, Rob Williams

I sort of worry on USparc because the user-space is 32 bit, but kernel space is 64, which makes me worry that files too big would break fsck or something... Would python be able to support LFS in this sort of arrangement...

There is a section in the python docs (last I tried python.org was still down) regarding compiling python with LFS on 32bit platforms. You may want to check it out when compiling python. :) Bill _______________________________________________ Zope maillist - Zope(a)zope.org 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 )

Does this mean that my ZEO storage server, which runs on Debian 2.2 / Linux 2.4.5 on a Sun E450 would have LFS in the VFS layer on my plain-old ext2 partitions?

What I am trying to tell you, is that on RH 7.1, there is no additonal step needed. None, zip zilch nada, to support large files. install normally. This is true of ANY distribution that uses a kernel version 2.4.0 or higher. Period. The VFS is in the _kernel_ not the filesystem. If you install aplain-jain RedHat 7.1, you already have support for large files, period. There is no Filesystem option for it because there cannot be. The filesystem is _irrelevant_. whetehr python itself has issues, is an entirely separate matter. yes, there are patches ot the Installer for other filesystems, but, again, this has nothing to do with large files support (LFS). SuSE is certianly not the only distro 'supporting' large files, as any distribution that uses the Linux Kernel v2.4 or above has it. period. In fact, last I recal, ReiserFS on kernel version below 2.4 have the limit, simply because the limit was NOT an ext filesystem limit, rather a Linux KERNEL issue. Of course, this problem was limited to intel machines, on, say, a DEC(COMPAQ) Alpha machine, ext has been handling large files just fine for quite some time. it was never an issue there. There are reasons to prefer other filesystems, such as ext3, or XFS, but the 2Gb problem, on kernel 2.4+, is not one of them. So, in order to get LFS in the most simple manner: Install any distribution of linux that uses the 2.4 series of kernels (ie. Redhat 7.1, I believe mandrake 8, though I do not recommend that for a server, and I am sure the latest version of SuSE and Debian). Do a *normal* install, no further effort needed. Period. > > For many of us, installing linux is by far the hardest part :) Then you've got it made :) Bill _______________________________________________ Zope maillist - Zope(a)zope.org 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 )
