[Zope] Zope 2.8.4 - ZEO ClientStorage cache problem
Hi!
I have a problem with my instances of Zope 2.8.4: recently they started
to run slowly. Restarting doesn't help much.
After observing Zope threads with DeadlockDebugger we found that very
often threads are stuck while trying to access to ZEO cache file.
We have ZEO server and 2 ZEO clients. Each client has 10 threads.
Example output from DeadlockDebugger (attached at the end of this
message) shows that a lot of threads is executing self._lock.release()
in loadEx function. Attached dump is from ZEO Client instance.
I wonder how it is possible that so much threads in this dump are
releasing lock in the same time? Shouldn't they stay on acquire?
We did more dumps from DeadlockDebugger. Almost every time dump shows
that there are some threads that are doing something in loadEx, like:
(...)
File "/opt/Zope/2.8.4/lib/python/ZEO/ClientStorage.py", line 755, in loadEx
self._lock.release()
File "/opt/Zope/2.8.4/lib/python/ZEO/cache.py", line 194, in load
return o.data, tid, o.version
File "/opt/Zope/2.8.4/lib/python/ZEO/cache.py", line 1010, in access
return Object.fromFile(self.f, key)
Seems to me that access to ZEO cache is a deadlock there, but I don't
know why. Why it is so often and so slow(?) that I can see it in
DeadlockDebugger almost every time? I don't remember seeing loadEx on
output from DeadlockDebugger before.
I've checked disk I/O and it is ok. Event log shows:
2010-04-07T13:48:03 WARNING ZODB.DB DB.open() has 13 open connections
with a pool_size of 7
which is our bad, as we have 10 threads and too small pool_size=7, but
I'm not sure if this matters. I wonder that maybe, under heavy load,
when sometimes all 10 threads are used, Zope has to continuosly create
and destroy Connection objects and this causes "filling/flushing" their
caches - I have no idea if this works that way?
Any ideas what might be wrong, or what can I check?

Zope database is object database, what means it stores objects, not files, so you shouldn't expect files to be there. These are all objects. Even 'File' is instance of class 'File'. Some of these objects have methods that allow them to 'answer' to FTP requests, and you can see them in your FTP client. If some objects are not 'FTP enabled' you will not be able to use them via FTP. Take a look at group archives.

This is legacy code from zope 2.8.4 that I have to
deal with during migration. All new code is supposed to use
u'' strings.
In fact, above is only an example but in real case we
have properties set for folders, eg. 'title' that
contains national characters.
You can easily check it yourself if you want.
Just create a Folder and set it's 'title' property
to one that contains some unicode characters.
You'll not be even able to add ZPT object into
that folder I think (at last it is not possible for me).

What do you mean by internal ZPT encoding? Docs says:
"Starting Zope 2.10.2 the ZPT implementation uses unicode as internal
representation"
so there should be no encoding at this level, I think.

I already realized same thing and used sitecustomize.py
with sys.setdefaultencoding('utf-8') as a quick fix. This works
but is not nice solution. I rather expected Zope 2.10 resolver to
deal with this.

[Zope] UnicodeDecodeError in Zope 2.10.4 (upgrade from 2.8.4)
I've upgraded my installation from Zope2.8.4 to Zope 2.10.4
(by copying data.fs, Products/ etc.). I have publisher encoding
and management_page_charset set to utf-8. Also system
default encoding is utf-8.
Zope 2.10 is said to have better Unicode support with
UnicodeEncodeConflictResolver. It is but unfortunatelly in
some cases this is not enough. Seems that
code that is 'protected' by Resolver is not the only code
that may be affected by non unicode strings.
Simple example is with 'structure' keyword.
eg:
This works (resolver resolves conflict):
template id.
This doesn't work:
template id.
Also if you have Folder instance and set it's Title
to the string that contains some i18n characters
you're not able to even add page template
inside it.
Error traceback in both cases is same:
Error Type: UnicodeDecodeError
Error Value: 'ascii' codec can't decode byte 0xc5 in position 200:
ordinal not in range(128)
Traceback (innermost last):

problem is with:
text = unicode(structure)
at
Module zope.tal.talinterpreter, line 754, in do_insertStructure_tal
sitecustomize.py with setdefaultencoding('utf-8') solves this
but it is not nice solution. I wonder whether this should be
submitted as a bug, or maybe there is different solution that
I've missed?
For the record: one more thing that was wrong
for me during migration was 'expand' attribute of ZPT
that in case of few ZPT objects was set to true in
2.10.4 while oryginally in 2.8.4 it was false.
This caused that tales expressions disappeared
from ZPTs under 2.10.4. I've written a script that
explicitly set expand=0 to all ZPT instances in
Zope 2.8.4 and then, after migration, everything is OK.

Then you should set View permission for authenticated users only (or something like that). This is typical Zope security machinery. Then you add PAS object into secured folder - this will create new 'acl_users' object. In 'acl_users' you need to add two plugins from the list: 1. Cookie (don't remember the name) 2. ZODB UserFolder Then you have to Activate added plugins (you'll find activation at properties or at 'plugins' object). Thats all. Now, at ZODB UserFolder object you may add users just like with default acl_users.

There were some benchmarks (or sth like that) showing that bigger number of threads doesn't help too much to performance, and it may be even worse. In your setup, if you have 25 threads you should have pool size bigger than 25 - every thread will possibly use ZODB so it should have connection to use. In fact connection is created as needed, even if pool_size is too small. That is why number of connections in your logs is bigger than pool_size. -- Maciej Wisniowski ___ 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 )

If you've opened pop up window "with php" then in fact it had to be
JavaScript. Possibly you're looking form something like:
if (confirm("Do you really want to remove this picture"))
return true
return false
which may be used with onsubmit event of form object. Of course
this is javascript code not python.

Possibly your Zope doesn't start because of some errors. Take a look at log/event.log to see if there are any errors at the end of this file.

Why don't you just export object path along
with it's data? use |getPhysicalPath() for example.
Take a look at http://plope.com/Books/2_7Edition/AppendixB.stx#2-396 for
description.
Also consider use of restrictedTraverse to get access to object that you
will
add newly created objects to (during import).
Sth like:
container = self.|restrictedTraverse('/SITES/plone_mySite/repertory1/")
container.invokeFactory
Or something like that.
> My subject is reindexObject because I think it's this function that

AFAIK reindexObject is used to reindex object in Catalog.
invokeFactory puts new object of the specific type to ZMI.

I don't understand what you mean. Field objects already are persistent. EM gives you no security restrictions in comparision to Script Python.

With ExternalMethod you only have to hit save button again to refresh it. Simple external method code that you may use to traverse through ZODB: def checkFolder(self, fld): for obj_name, obj in fld.objectItems( 'FormulatorForm' ): # get form fields here etc for fld_name,fld_obj in fld.objectItems( 'Folder' ): checkFolder( fld_obj ) for fld_name,fld_obj in fld.objectItems( 'Folder (Ordered)' ): checkFolder( fld_obj ) I'm not sure about 'FormulatorForm', this may be 'Formulator Form' or something like that. -- Maciej Wisniowski ___ 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 )

This seems to be hardcore ;) I mean that it should not
be necessary to do such rewrite of all keys and values
for dictionaries or lists taken from session.
I never had to do something like that...
Isn't it working without these assignments? Just:
order=req.SESSION.get('order', []) # if there is no 'order' in session
# you'll simply get empty list here
new_order = {}
for val in req.form.keys():
new_order[val]=req.form[val]
order.append(new_order)
req.SESSION['order'] = order
BTW. req.SESSION.set(..., ...) method is also persistence aware
(according to zope book)

Maybe it is because of req.form assignment. Try to create copy of
its values and append this to 'order' list like:
session = context.REQUEST.SESSION
order = session.get('order', [])
order.append({'foo':req.form['foo'],
'bar':req.form['bar']})
session.set('order',order)
and see what happens now.

Which bug reports? Stored procedures implementation in DCOracle2 (original implementation) under some conditins may cause that behaviour (no rollback). I've written about this on Zope-db (http://permalink.gmane.org/gmane.comp.web.zope.general/56435). But this is very specific thing possibly connected with a bit strange (at last for me) Stored procedures implementation in DCOracle2 (they're resource managers itself) and AFAIR they're using other resource managers. I've solved this by changing ZOracleDA Stored Procedures to behave similarly to ZSQLMethods. Another thing is that Zope database adapters usually use volatile attributes and as Dieter Maurer told me (on zope-db) under some (very specific) conditions (AFAIR subtransaction commit or something like that) this may cause connection object stored in volatile attribute to disappear during request. -- Maciej Wisniowski ___ 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] database connection in script
> how to create a database connection in a script python
This is your third (or more) thread about this during few hours!
Ask a specific questions and be patient please.
In general seems that you have no idea how it all works.
So my advice is:
1. Read abour basics of relational database connectivity in zope
2. Go to your portal folder via ZMI and create database
connection to your RDBMS
3. Still in ZMI create ZSQLMethods you need
4. In your product just call these ZSQLMethods via their id's like
result = self.mymethod1()
If this works then you may:
1. Change addform of your product to be able
to select specific database connection from the list
of available connections. Your product won't have
hardcoded connection id.
2. Create ZSQLMethods in your product as typical objects.
Instead of using ZSQLMethods you may use:
context.db_conn_id.db.query('YOUR QUERY HERE')
as Robert Rottermann suggested.

Please stay on zope list too! I've never used tramline, but after reading short description on their page seems that you'll have simpler configuration: - server A with Apache(and tramline) and a rewrite rule to Zope(8080) - server C with MS SQL Server - *without any webserver* - connected with ZODBC - firewall that send any incoming connection for www.mydomain.it to server A when protocol is http or https In general seems that instead of real, large files, app server receives only small files that contain only unique identifiers of these real ones. Real files are handled by tramline and stored in specific filesystem folders. When someone requests a file for download, application server sets special header that contains unique file identifier and this causes that tramline will return real, big file to the browser. Upload similarly uses headers to allow or disallow uploading. -- Maciej Wisniowski ___ 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 )

AFAIK it uses tempfile for serving such files. This allows Zope resources to be not blocked while returning big amounts of data. Although creation of tempfile or something like that (I'm not sure how this works in details) may still be slow. In general serving static files is best done by servers like Apache and I think this shouldn't be done by application server like Zope (possibly until it has blobs support). I don't understand why you can't use tramline. It may be connected with zope easily. It gives you very fast filesystem storage. Even more, seems for me that it is designed to do exacly what you're asking for. You say that tramline may help you after resolving zope issues, but I don't get it...

Yes, right. I tried to write this with 'always': "not served (always) directly by Zope/Plone instance" :) > Caching will not > make any difference to memory behavior I'd say. I'm not expert here, so I might be wrong but AFAIK Zope instance loads 'touched' objects from ZODB into cache. Each ZODB connection has its own cache, so having object touched more than once may cause it is loaded to more than one cache. The same will possibly be with multiple ZEO clients. External cache will save them from being touched (sometimes even once). ZODB connections cache is cleaned sometimes, so it should flush objects that are old and possibly save some memory then. I don't know whether amount of memory used because of above is huge enough to cause described problem. It's just a though.

Standard CookieAuthHelper and ZODBUserManager plugins are not enough for your use case? Seems that your problem (that you start like a Member but after clicking somewhere else you're unauthenticated) is because of code in extract credentials. What happens there? Credentials are extracted from request. So, if you have __ac_name and __ac_password in the request you're authentictated. When you're visiting another url, there is no __ac_name and __ac_password in request anymore, so you become unauthenticated. Right? So you have to store somewhere information about sucessful login. Solution might be the code I've sent you in previous mail. After authentication with __ac_name and __ac_password from the request it stores data in session. Then, on another pages session is checked for credentials and... you should be still authenticated. Another solution is to just use CookieAuthHelper which stores data in cookies. This is first part. You have credentials. Second thing is to compare them with users stored in ZODB (that what ZODBUserManager is doing...) -- Maciej Wisniowski ___ 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] session
> i did it, but it don´t work,
Because this code has no sense this way.
You're just storing and retrieving data from session.
What do you suppose this will do...
Try something like:
def extractCredentials(self, request):
creds = {}
session = self.REQUEST.SESSION
creds = session.get('_key', None)
if creds:
return creds
login = request.get('__ac_name', '')
if login:
# Look in the request for the names coming from the login form
login = request.get('__ac_name', '')
password = request.get('__ac_password', '')
if login:
creds['login'] = login
creds['password'] = password
if creds:
creds['remote_host'] = request.get('REMOTE_HOST', '')
try:
creds['remote_address'] = request.getClientAddr()
except AttributeError:
creds['remote_address'] = request.get('REMOTE_ADDR', '')
session.set('_key', creds)
return creds
return None
You should use protected class (like in CAS4PAS) to store credentials
in session. Also you should think how it is supposed to work and what
should be done in extractCredentials and what in authenticateCredentials
functions, etc.
So far this code checks if there is object in session and if so then it
extracts
credentials from this object, if no, then it tries to extract credentials
from request.
You should now validate these credentials with something (eg. RDBMS),
possibly in authenticateCredentials function.

Please stay on list.
Something like:
session = self.REQUEST.SESSION
session.set('_key', credentials)
to retrieve data:
creds = session.get('_key', None)
So after proper authentication you may store object with
user name etc. in session and later just check if it is there.
If so, then user is authenticated...
In general this is how CAS4PAS plugin works.

I meant that I don't believe that it is typical to distribute new version of application between Zope instances by copying data.fs. Is this misbelief? In general OP asked about securing Zope sites. One way is to create proper environment with few Zope instances e.g. developement, test, production and more if someone needs (for example I have internal and external test instances).

For me there should of course be another developement Zope instance (and test instance and more), but application should be moved between instances by 'copying' changed Products or exporting changed files/folders from ZODB (.zexp files), or something like that.

I don't understand what you're doing.
Can describe your use case, please?
So far I know that you want to 'validate if user exists',
but where are your users defined? RDBMS? ZODB?
You should have plugin that implements:
IUserAdderPlugin interface. What plugin is this
in your environment?
Take a look at plugins/ZODBUserManager.
This plugin has three attributes:
self._user_passwords = OOBTree()
self._login_to_userid = OOBTree()
self._userid_to_login = OOBTree()
and it stores user data there.
Then it's authenticateCredentials is able to
check if user with specific login and password
exists there.
