[Zope] Getting records X to X+20 of catalog search
Dear All, How do we get records X to X+20 of a catalog search ? We're aware of the limit parameter of the search () function, but this only gives us the top Z rows. If I want to show records 90 to 100, I'm trying to avoid having to fetch records 1 to 89.

RE: [Zope] Making Zope stop storing old object versions
Thanks Jonathan. But I thought you were referring to a way to make Catalog writes transparently write to MySQL. The article you're pointing to teaches how to use use ZSQLMethods, which we're already doing. But the product we're using to do workflows (OpenFlow) uses the Zcatalog. So we either rewrite it to use MySQL, or we find a way to make Catalogs write to MySQL.

What it does not is removing the old version - this is done during packing. When you have many Catalog writes or other parts of your object tree experiences many writes, try to mount an extra ZODB (and storage) there. You can also try some of the other storages like relstorage (where it depends on the RDBMS how it handles writes) Alternatively, you could just replace your Catalog with an external db such as MySQL (using zmysql database connections).

[Zope] Turning back system clock
Dear All, The system clock of our Zope 2.7 machine accidentally got set to 2009. We noticed this mistake 6 hours later and we decided to set back the clock to 2008. How does this affect the integrity of Data.fs ? From our observation : 1. Session write errors suddenly began to appear 2. Data.fs.index won't grow anymore and its timestamp remained at the time we set back the clock 3. Packing the database (which was 8 GB at the time) took too long without any signs of any Data.fs.pack file in the var folder. We decided to restart Zope after a few minutes. 4. There seem to be some catalog indexing problems as our catalog searches on a certain field doesn't work as reliably as it did before. We tried reindexing the field and even the catalog, but it timed out on us (lots of objects in the database). Has anyone here had any similar experiences ? How do I go about fixing this ? Using repozo.py last night, I made a full backup of Data.fs, copied it to a new instance, was able to create a new Data.fs.index, and eventually succeeded in packing the 8 GB database to just 2.4 GB. But it took quite a while - like 10 or 15 minutes before any Data.fs.pack appeared. I haven't checked yet if the catalog indexing problem has gone away.

[Zope] RE: Zope hangs when database takes too long to respond
It is a known limitation of Zope, which has a set number of worker threads available to service user requests. If a worker thread blocks (e.g., waiting for MySQL), it is not able to do any work for other pending requests. You can tweak the number of threads in your zope.conf file, via the 'zserver-threads' directive (the default value is 4). If you do increase this value, you also need to increase the number of database connections avialble (via 'pool-size') which will increase the RAM required by your appserver. Thanks Tres. I found 'zserver-threads' in zope.conf, but couldn't find 'pool-size'. Am using Zope 2.7.6. Is this something available on higher versions of Zope ?

RE: [Zope] Zope hangs when database takes too long to respond
Seems that all your Zope threads are busy (they're waiting for database response). There is no more threads to serve next requests so they're waiting (you may say that zope hangs in this situation, but in fact all it's threads are waiting for DB).

RE: [Zope] The id s5/begin contains characters illegal in URLs
Huh? Usually you have no chance to create a Zope object with such an
id.
So there is no need to rename something that can't exist be definition
:-)
Exactly.
The said object, s5/Begin, is the Begin activity of the s5 process
found in the GeneralWorkflow workflow - which is an OpenFlow (
www.openflow.it ) object.
I was able to rename my processes (S5, S100, S200) to their lowercase
counterparts since all I had to do was do :
///
wf = container.GeneralWorkflow
catalog = wf.Catalog
processes = catalog.ZopeFind(wf, obj_metatypes=['Process'],
search_sub=1)
for p in processes:
wf.manage_renameObject(p[0], p[0].lower())
///
When I try to rename the activities found in those processes, I try to
do likewise, but the ZopeFind results come out like this :
('S100/Begin', activity at /dev/danny/wms/GeneralWorkflow/S100/Begin)
('S100/RECEIPT_OF_SOURCE_DOCUMENTS', activity at
/dev/danny/wms/GeneralWorkflow/S100/RECEIPT_OF_SOURCE_DOCUMENTS)
('S100/CHECK_MS_BATCHING', activity at
/dev/danny/wms/GeneralWorkflow/S100/CHECK_MS_BATCHING)
To call manage_renameObject (), I have to supply it with the object
name.
If I use result[0], I get the illegal characters in URL error.
And if I use result[1].id, I get :
Error Type: AttributeError
Error Value: Begin
This is probably because there is no Begin object under the wf
container from which I'm calling manage_renameObject().
So my question is, how do I refer to the Begin object found in the
S100 workflow ?
Regards,
Danny

[Zope] Zope performance experiences
Dear All, Can anyone share their experiences on Zope's performance, what your hardware / Zope configs are, and how you plan to scale ? Regards, Danny ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
RE: [Zope] Searching for and displaying properties
manage_addProperty does not trigger recataloguing of the object even
if its a subclass of CatalogAwareness. You should ? either call
obj.reindex_object() or at least obj.index_object(), if your class has
the CatalogAwareness-Mixin or you use the catalog API:
yourcatalog.catalog_object(obj,obj.absolute_url_path())
After that, your metadata should show up nicely w/o indexing the whole
object tree.
Thanks Tino.
I'd like to try your suggestion, but I don't know how to refer to the
object that needs recataloguing. Can you help ? Again, here's my code
that calls manage_addProperty.
code
wf = context.GeneralWorkflow
instance_id = wf.addInstance( process_id=process, customer=jobname,
comments=comment, title=subject, activation=1)
wf.getInstance(instance_id).manage_addProperty('jobname', 'ABC12345',
'string')
/code

RE: [Zope] Searching for and displaying properties
'jobname' is added as *metadata* to your catalog?
Not sure if using manage_addProperty () to add jobname is equivalent to
adding it as *metadata* .
code
manage_addProperty('jobname', 'ABC12345', 'string')
/code

RE: [Zope] Searching for and displaying properties
This add a property to an object but it has nothing to do with adding *metadata* to a ZCatalog instance. Please read the ZCatalog chapter of the Zope Book 2.7 edition. It carefully explains what *metadata* in the ZCatalog context means. The short version: a Zcatalog search returns *proxy* objects and the attrs of the proxy object contain only the values of the original object where you have configured a metadata in the Zcatalog. Having read the Zope 2.7 ZCatalog chapter, I think I can say there's always been a metadata column called jobname. So going back to my original question, is there a way for me not to have to mass-refresh my entire catalog just to be able to display my properties ?

RE: [Zope] Searching for and displaying properties
Click on update catalog in the Advanced tab or use the refreshCatalog() method of the ZCatalog (described in its interfaces.py file). refreshCatalog() is exactly what I was forced to use in the first place. I was wondering if there exists an alternative function / method that won't require refreshing / reindexing the entire Catalog.

RE: [Zope] Searching for and displaying properties
That's the official ZCatalog API. Otherwise find your objects through
a catalog search and reindex them individually.
I already did the reindexing just before the search and it didn't work.
In any case, I may have found a workaround by using getObject().
According to
http://www.plope.com/Books/2_7Edition/SearchingZCatalog.stx#2-10 :
getObject() Returns the actual zope object from the result object. This
is useful if you want to examine or show an attribute or method of the
object that isn't in the metadata--once we have the actual object, we
can get any normal attribute or method of it. However, be careful not to
use this instead of defining metadata. Metadata, being stored in the
catalog, is pre-calculated and quickly accessed; getting the same type
of information by using getObject().attribute_name requires actually
pulling your real object from the ZODB and may be a good deal slower. On
the other hand, stuffing everything you might ever need into metadata
will slow down all querying of your catalog, so you'll want to strike a
balance. A good idea is to list in metadata those things that would
normally appear on a tabular search results form; other things that
might be needed less commonly (and for fewer result objects at a time)
can be retried with getObject.
I tried it and it works. My code now looks like this :
code
wf = context.GeneralWorkflow
cat = wf.Catalog
jobs = cat.searchResults({'jobname':'ABC12345'})
for j in jobs:
print j.getObject().jobname
return printed
/code
My only question now is ... How much slower is this solution than using
the jobname metadata (assuming it worked).

[Zope] Streaming files
Dear List, Am a newbie so please bear with me. I need Zope to stream files to my users when they click on a link. Exactly how is this done ? Is it by the use of the Request.Write () method ? If so, canyou give me sample code and some reference links ? Thanks.
