RE: [Zope] EXT2 has nothing to do with it

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? Supposing I can get my Python compiled with large file support... hmm. food for thought - or a chance to break something... either way...

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 )

guarded_getattr attribute error with complex Python structures
by Pierre-Julien Grizel 03 Aug '01

03 Aug '01

Hi, I've got a complex Zope problem... I have a resonably deep imbrication of Python scripts & DTML Methods. It happends that I finally do something like this : MyScript: return MyMethod(LIST, RECORD_SET) MyMethod: <dtml-in LIST> xxx </dtml-in> As you can guess, LIST is a... list (actually a list of tuples built from another Py script). When I try the URL, I eventually got the following traceback : Traceback (most recent call last): File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_Try.py", line 221, in render_try_except result = render_blocks(self.section, md) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_Util.py", line 230, in eval return eval(code, d) File "", line 2, in f File "/isp/zope/smartway/lib/python/AccessControl/DTML.py", line 104, in guarded_getitem return guarded_getitem(ob, index) File "/isp/zope/smartway/lib/python/AccessControl/ZopeGuards.py", line 151, in guarded_getitem v = object[index] File "/isp/zope/smartway/lib/python/OFS/DTMLMethod.py", line 187, in __call__ r=apply(HTML.__call__, (self, client, REQUEST), kw) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_String.py", line 544, in __call__ try: result = render_blocks(self._v_blocks, md) File "/isp/zope/smartway/lib/python/OFS/DTMLMethod.py", line 187, in __call__ r=apply(HTML.__call__, (self, client, REQUEST), kw) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_String.py", line 544, in __call__ try: result = render_blocks(self._v_blocks, md) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_With.py", line 148, in render try: return render_blocks(self.section, md) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_Return.py", line 104, in render val = md[name] File "/isp/zope/smartway/lib/python/OFS/DTMLMethod.py", line 187, in __call__ r=apply(HTML.__call__, (self, client, REQUEST), kw) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_String.py", line 544, in __call__ try: result = render_blocks(self._v_blocks, md) File "/isp/zope/smartway/lib/python/OFS/DTMLMethod.py", line 187, in __call__ r=apply(HTML.__call__, (self, client, REQUEST), kw) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_String.py", line 544, in __call__ try: result = render_blocks(self._v_blocks, md) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_With.py", line 148, in render try: return render_blocks(self.section, md) File "/isp/zope/smartway/lib/python/OFS/DTMLMethod.py", line 187, in __call__ r=apply(HTML.__call__, (self, client, REQUEST), kw) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_String.py", line 544, in __call__ try: result = render_blocks(self._v_blocks, md) File "/isp/zope/smartway/lib/python/OFS/DTMLMethod.py", line 187, in __call__ r=apply(HTML.__call__, (self, client, REQUEST), kw) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_String.py", line 544, in __call__ try: result = render_blocks(self._v_blocks, md) File "/isp/zope/smartway/lib/python/OFS/DTMLMethod.py", line 187, in __call__ r=apply(HTML.__call__, (self, client, REQUEST), kw) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_String.py", line 544, in __call__ try: result = render_blocks(self._v_blocks, md) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_In.py", line 770, in renderwob try: append(render(section, md)) File "/isp/zope/smartway/lib/python/OFS/DTMLDocument.py", line 192, in __call__ r=apply(HTML.__call__, (self, bself, REQUEST), kw) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_String.py", line 544, in __call__ try: result = render_blocks(self._v_blocks, md) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_Let.py", line 148, in render return render_blocks(self.section, md) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_Util.py", line 230, in eval return eval(code, d) File "", line 2, in f File "/isp/zope/smartway/lib/python/Shared/DC/Scripts/Bindings.py", line 324, in __call__ return self._bindAndExec(args, kw, None) File "/isp/zope/smartway/lib/python/Shared/DC/Scripts/Bindings.py", line 354, in _bindAndExec return self._exec(bound_data, args, kw) File "/isp/zope/smartway/lib/python/Products/PythonScripts/PythonScript.py", line 363, in _exec result = apply(f, args, kw) File "Script (Python)", line 1, in html_results_list File "/isp/zope/smartway/lib/python/OFS/DTMLMethod.py", line 187, in __call__ r=apply(HTML.__call__, (self, client, REQUEST), kw) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_String.py", line 544, in __call__ try: result = render_blocks(self._v_blocks, md) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_In.py", line 768, in renderwob push(InstanceDict(client, md)) AttributeError: guarded_getattr This happens in fact quite every time I'm handling complex Python data structures and passing them through scripts and/or methods...

Hi, I'm creating a few DTML Documents from a python script. For example: id='something' title='something' context.manage_addDTMLDocument(id,title) doc = getattr(context,id) I have a Ram Cache Manager in the root that I'd like to associate this new document with. How do I do that from python? thanks much -Kevin __________________________________________________ Do You Yahoo!? Make international calls for as low as $.04/minute with Yahoo!

Internationalization

Hi people! Does anybody know a decent way to render non-english-characters (i.e. ¿,¡,á,Á,é,É,í,Í,ó,Ó,ú,Ú,ñ,Ñ, etc.) using html entities format (á Á é and so on)?. This is what I'm trying to do: accented_value(:text)= "Hél o' wórld. ¿bláh?, ¡bláh!." <dtml-var "REQUEST[accented_value]" html_quote_it_please> html_quote does not perform tyhis job.

Getting counts from a ZCatalog - it must be easier than my feeble attempt!
by S.Wilson 03 Aug '01

03 Aug '01

Hi all, I need to find out how many results would be returned from a search, without necessarily getting the results set itself. Currently the only way I can do this is to iterate through a zcatalog using <dtml-in> and add up the number of items. <dtml-var> does not support functions such as len(), but I'm convinced I'm missing something, and there is a considerably more elegant solution to this one... Here's my code: 1: Subjects 2: <dtml-in expr="('SubjectContext'),('AudienceContext')"> 3: <dtml-let sIndex=sequence-key> 4: <dtml-in expr="articleIndex.uniqueValuesFor(sIndex)" > 5: <dtml-call "REQUEST.set('nItemCount',0)"> 6: <dtml-in expr="articleIndex({sIndex:_.getitem('sequence-item')})"> 7: <dtml-call "REQUEST.set('nItemCount',nItemCount+1)"> 8: </dtml-in> 9: <a href="/index_html?<dtml-var sIndex>=<dtml-var sequence-item>"> 10: <dtml-var sequence-item capitalize> 11: </a> 12: (<dtml-var nItemCount>) 13: </dtml-in> 14: </dtml-let> 15: </dtml-in> 16: which outputs a side menu bar looking something along these lines: Subjects: Assessment (2) Content (3) Metadata (5) For Developers (5) For Educators (3) For Members (2) What I'm looking for is something like: <dtml-var expr="len(articleIndex({'SubjectContext':_.getitem('sequence-item')})[0])"> to replace lines 5,6,7. Unfortunately this gives me an error. Any ideas? Thanks, Scott Zope Newbie

Trivial DTML question
by Dan Jacobs 03 Aug '01

03 Aug '01

In a folder, I have a set of DTML Methods and an ordered "lines" property that contains the names of the Methods I want to call. So in my DTML Document I have: <dtml-in items_order> <dtml-var expr="_.getitem('sequence-item')"> </dtml-in> This produces the names of the Methods. But I want the outputs of the Methods. If I try <dtml-var expr="_getitem(_.getitem('sequence-item'))"> then that gives me the HTML-quoted bodies of the Methods rather than their HTML output. How do I call the Methods instead of merely reading them? -- Yoz, on Dan's computer

ZCatalog Search Interface Broken (help?)
by Gary Perez 03 Aug '01

03 Aug '01

Hi, all. First, the versions: Linux, Zope 2.3.0, python 1.5.2 A while back, I set up a couple of Catalog-aware ZClasses that auto-update to a Catalog in Zope's root folder. In that same folder, I added the standard "Z Search Interface". Somemtime within the last couple of months, the search interface stopped working; searching on any of the indexed properties of either ZClass returns no results whatsoever. Here are the things I checked in various combinations, multiple times: - Create new ZClass(es): they still auto-update in the Catalog, search fails - Update the Catalog: looks good, search fails - Verify the Indexes of the Catalog, redo "Find Objects": works fine, search fails - Trash original "Search_Form" and "Search_Report" DTML Methods, add new from management interface: use Zope defaults, search fails During the last month or so, I removed one property from one of the ZClasses, and added a different one... neither of which were ever (nor will ever be) indexed by the Catalog or searched for via the interface. Has anyone run into a similar problem (and, hopefully found a solution)? Thanks in advance for your zen & guidance. -Gary

Temperamental Zope+Windows
by Tim Fouracre 03 Aug '01

03 Aug '01

Whenever I am using Zope (Version 2.3.3) and Windows 98 crashes/locks up (so quite freqently) and I hit ctrl-alt-del, I always have to run scandisc when the computer restarts. If i don't, Zope will not work. Normally I would just cancel the laborious scandisc process, and everything would be fine. But Zope is always adversely affected by the crash/lock up and needs sectors that contain some of its files to be repaired. I was just wondering why? as this doesn't happen with any other programs I use.
