[Zope] Removing Zope and Python version info from request header

Anyone have a quick pointer? ___ Zope maillist - Zope@zope.org https://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - https://mail.zope.org/mailman/listinfo/zope-announce https://mail.zope.org/mailman/listinfo/zope-dev )
[Zope] Session question
Zope 2.8.9.1 on Linux with ZEO
One admin client on box1
One search client on box1
Three public clients on box2
ZEO server and storage on box3
We have sessioning set up as own storage FS in ZEO.
Often, when referencing a session object, we get a key error that the
session object does not exist.
Most of the time, just a refresh or two will fix it but not the ideal case.
When I pack the session fs, even if I go to zero days, it only shrinks
down to about 220meg when it used to be about 32K (if I remember
correctly) after a zero days pack. Like a clean slate. The session.zec
file stays about 20meg.
Just curious how this all works and trying to pinpoint the problem. Have
tried deleting the zec files from all clients, packing the session.fs
file and flushing the cache and restarting all 5 clients only to have it
back to 220meg and the same 20meg zec file.
Not sure where to look next.
Thanks
-Allen

Re: [Zope] persistent sessions with ZEO not working
What we did was create a Session.fs and added to the zope and zeo conf files.

Any ideas? Verify that "session_folder" is a mount point and not a regular folder. This is not trivial as a mount point, once mounted, tries hard to become the mounted object (this happens in its "__of__" method). You must avoid acquisition to check that it is indeed a mount point. One way is to use "app._p_activate(); app.__dict__['session_folder']". This must return a mount point, not a folder. I verified using your process that it is indeed just a folder. So I deleted the session_folder in the root and then tried to add a ZODB mount point in the root and it showed the session_folder was ready to be created. I made sure that option was checked and clicked Ok. It reloaded the root folder and the new session_folder was there, but it still seems like it is just a regular folder and does not identify itself as a mount point. I also added the session_data object into that folder as a Transient Object Container as it was before. Does the session_data_manager that points to that session_data folder also have to be removed in this process?

The so called session_data_manager tells Zope where the
session_data is located.
Apparently, your session_data_manager does not look at
the place of your mount point or your mount point does not work/is not
active.
First verify the session_data_manager configuration (this easy -- look
in the ZMI).
If this is correct, verify the mount point.
That is not so easy. The best way is to start an interactive
Python interpreter (bin/zopectl debug on *nix).
Then use
folder = app.unrestrictedTraverse('path_to_folder_containing_the_mount')
folder._p_activate() # load the folder
folder.__dict__['Id_of_your_mount_point']
You should see an ZODBMountPoint (or something along this lines).
If you really see a mount point, verify its configuration
(that's easy again -- thus, you can do that before the more
difficult step): is the mount point really in the storage you want?
I completely missed this response.
Still having this issue so going back over this again.
Can you identify which things and where for the items above?
path_to_folder_containing_the_mount and ID_of_your_mount_point
This is in the zope.conf:
zodb_db session
mount-point /session_folder
zeoclient
server blahblah.com:
storage session
name session
client session
var $INSTANCE/var
/zeoclient
/zodb_db
This is in the zeo.conf:
filestorage session
path $INSTANCE/var/Session.fs
/filestorage
In the ZMI, there are:
/session_folder/ ( a regular folder )
session_data ( Transient Object Container )
/session_data_manager ( Session Data Manager )
All the parts seem right but its not workingsession writes wind up
as anonymous transactions in the main ZODB.

To be honest the 3.0 version of the ZMySQLDA isn't bad and some of the errors may be related to other things - I've recently had a project with key errors on cached ZSQL results which are independent of the DA.

Your ZODB contains an object referencing another object with object id
"0x18fb01" but this object is missing (not in the ZODB).
I.e., you have a dangling (persistent) reference.
You can use the "fsrefs" utility to check for such dangling references.
It will tell you about the referencing object and its broken references.
You can fetch the referencing object and try to fix it (there is a
HowTo somewhere how you can approach this).

[Zope] Question about Roles
Zope 2.8.9.1 I have a user in the root acl_users but no Roles set. Then I go into the folder I want the user to have access in and using Local Roles, I assign Manager. Then on the page I use: dtml-if 'Manager' in _.SecurityGetUser().getRoles() show the update and delete form buttons /dtml-if For me, with Manager assigned in the root, I can see the buttons. But for this user, the buttons are not there. When I dtml-var the above getRoles() she only shows as 'Authenticated' but not 'Manager' and I show both. Just wondering why??

That makes sense...but I think they are still related, sort of.

Re: [Zope] problem migrating ZClasses from Zope 2.6.1 to Zope 2.9.8
That sounds so easy. We have one ZClass but it is the basis of almost our entire newspaper website. The news ZClass was built in 2000 and put into production when we went live on Zope in Feb 2001 (just before the guys at Zope Corp said that ZClasss were bad). Over 7 full years of daily news as ZClass objects. We are in the same boat as we want to move from 2.7.5 to a later version. We could switch to SQL articles but then we would have to make sure all the old URLs still functioned as our content is all over the search engines...and convert everywhere there are tools to manage story creation, importing, editing, etc. Yuck. We could just make the cutover one day and just keep an instance running for the old stuff and all new stuff runs from SQL. Has anyone every built tools to inspect a ZClass and produce a python product on the other end? That would be slick...but probably not worth the effort if only a few still use them.

Re: [Zope] dtml Z SQL doubt
Just use REPLACE instead of INSERT. If REPLACE statement is able to determine a unique value for a row and sees that that unique value exists for a row, the valued will be updated. If it does not exist, a new row will be inserted. This is what I use with MySQL.

Say SQL (or whatever SQL like mysql has there) IIRC, mysql has some kind of UPSERT which should handle it. If not, stored procedure or trigger etc could do it.

Re: [Zope] pool_size
Used to use the debug a lot but then when we found DeadLockDebugger (DLD), I was hooked...mainly because there is no 'baggage' to loading the page. Debug actually uses one of the threads to show you that page. The content of the thread sorta looks like the whole REQUEST object, which is helpful sometimes too. DLD is fast (normally) and sometimes rather addictive to watch...to see what your servers are doing. We use ZEO and 2 public clients fronted by squid and a third we use as an internal admin client that is not served by squid. I just use a set of bookmarked tabs in FireFox and open a tab for each server. Then I just hit 'reload all' and see what they are all doing. Just my 2 cents.

Re: [Zope] Upgrading Zope
If you are using any zClass objects and have them cataloged, then you need to run a script against them to do the reindexing, as I found out that changed at 2.8. Also if you are using DTML and using any sorting within dtml-in segments, you will need to patch a file. Pages that use sorting on dtml-in throw a weird error. The patch works fine but since it sounds like no one who maintains core Zope uses DTML, that bug probably won't get really fixed. There is an outstanding ticket open on it. Those are the things I have found so far. We are on 2.7.5 and now that those issues are worked out we are working on our upgrade strategy.

I'd like to know if you think that such migration is feasible or if I'll encounter some problems. Do you think it is better to migrate to the latest version of the 2.x or 3.x branch?

Re: [Zope] Zeo Client hanging
I see references to asyncore.py near the end of the thread listing when
using DeadLockDebugger and seeing a stuck thread process. The tread
eventually clears out but sometimes an impatient user reloads, reloads,
reloads...and then all 4 threads are stuck on exact same thing. Then you
can see the same URL jump to the other Zope/ZEO client and same thing
happens there. Another few reloads and one user has effectively crashed
the siteuntil the threads clear themselves out. Usually is a catalog
search for a news article or something spanning our 6 years of online
news articles searching on the word 'bob' or something like that.
+1 for DeadlockDebugger... love it.

Install DeadlockDebugger and you'll be able to see what is
the state of your threads when Zope becomes unresponsive.
In the event log with tracing on we get
Trace zeo.zrpc.Connection(C) wait(16697) {server:8100} pending, async=0
There are hundreds to thousands of these until the server is restarted.
In the zeo log we get
Error caught in asyncore asyncore.py
error:(110,'Connection timed out')
I'm not sure what these errors are. Maybe firewall between zeo
server and zeo client closes the connections or something like that?
That was my guess too.

[Zope] dtml-in sorting bug (collector #1884)
r.__cmp__(x,y) requires y to be a 'r', not a 'ImplicitAcquirerWrapper' http://www.zope.org/Collectors/Zope/1884 I see this is a pending case but does anyone have any idea if it will be fixed in future releases? Finally got a 2.8.8 instance running with our Data (from 2.7.5) and was able to run the catalog index fixer with help from Chris Withers (THANKS!!) and all was looking good. The pages that looked up news stories from the catalog are looking good. Then I went to a page that displayed Houses (from ZSQL methods) and does a sort on the results as is the case in MANY pages we have. The top line is the result on the error page. Seems its a well know bug but does not look like its an issue to most but it is to us. Any ideas??

Re: [Zope] Parameter generating an exception? (also recataloging issue)
I will bounce this out since I tried this recently while testing an upgrade. We are on 2.7.5 and our 200K+ news articles are all ZClass objects and are cataloged. We setup a 2.8.6 instance and made sure all Products, Extension, etc. were the same. Copied our Data.fs and brought up the instance. I could browse around the site fine until I did anything that utilized the catalog to look up the news articles. Did not find anything. I could navigate directly to an article and it displayed fine. I then tried to clear the catalog and find objects of the zclass typeit found nothing. This has been a rather large stumbling block to us upgrading. Any ideas? No rush...no emergency ... but would like to upgrade sometime soon hopefully. thanks Allen Jonathan wrote: - Original Message - From: Tit-Liviu Leontin [EMAIL PROTECTED] To: zope@zope.org Sent: Wednesday, August 16, 2006 10:42 AM Subject: Re: [Zope] Parameter generating an exception?

Re: [Zope] Parameter generating an exception? (also recataloging issue)
Sorry. That is what I meant I did by trying to find the objects after clearing. The Find tab found none of those zclass objects. I am getting that test instance set back up again with our current Data.fs again and am going to try the manage_convertIndexes that Jonathan mentioned to see if that works. Thanks Allen Dieter Maurer wrote: Allen Schmidt Sr. wrote at 2006-8-16 11:07 -0400: ... I then tried to clear the catalog and find objects of the zclass typeit found nothing. When you clear the catalog, then it is cleared (i.e. empty). You won't find anything thereafter. You have to recatalog all objects that you want to be found by your catalog. I simple cases, you can do this via the catalog's Find tab. In more difficult cases, you need to write a script that uses catalog_object (maybe index_object) for/on the objects to be catalogued. ___ 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 )
