Hi all, a bugfix release of Webware for Python 1.2.1 is available for download. Note that Webware 1.2.x supports Python 2.6 and 2.7 only. For older Python versions, use Webware 1.1.3. Documentation and download links can be found on the new homepage: https://cito.github.io/w4py/ New Features: You can now specify attributes to be set on the root HTML element of the Page servlet.

I'm still experimenting in the background with a more modern release of Webware for Python based on WSGI. A prototype already runs quite fast and can make full use of all the available kernels/cpus, which is not possible with the existing threaded application server that is restricted by the GIL. I have some other plans for the new release as well, particularly support for Python 3. -- Christoph -- ___ Webware-discuss mailing list Webware-discuss@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/webware-discuss

In 0.9 and 1.0 the session sweeper loops run over the keys list, not over the dictionaries, simply because older Python versions did not support that. So the problem with duplicate session sweepers might well have existed, you just didn't notice it. Could it be the scheduler instances sharing some global task lists? I thought about that too, because it would be an explanation, but no, they don't. One explanation for the duplicate session sweeping could be that your tasks inherit from WebKit.Tasks.SessionTask instead of TaskKit.Task. Or that you inherit from Application and run __init__ twice. To debug the problem, you can put some print statement in the __init__() and run() methods of SessionTask and see when it is instantiated (should be instantiated once at the start) and how often it is run (should run once every 10 minutes, depending on your SessionTimeout). -- Christoph -- LogMeIn Rescue: Anywhere, Anytime Remote support for IT.

Am 07.12.2012 12:16, schrieb Sophana K: Yes, I'm creating a Scheduler instance. I didn't know I was supposed to use the one from the application. It's ok to create your own instance. But then the two schedulers will run as two parallel threads which needs more ressources and you can get these race conditions if both schedulers have tasks which access the session store. It's also convenient to use the application.taskManager() because it's started and stopped automatically together with the application. Is it normal that a scheduler instance automatically does session sweeping? Shouldn't the application create the task explicitely? But that's excactly how it works. The application creates its own scheduler, and then adds just one task, the one which is used for session sweeping. You can replace that task with your own or add more tasks if you like. I have now fixed my code to use the existing scheduler. Shouldn't you remove the previous fixes then? The fixes are still helpful in case anybody changes the session store for whatever maybe valid reasons. It's still unclear to me what caused your problems: Do your own tasks modify the session store? Then that's the explanation, because you ran them in a parallel scheduler. If your own tasks don't change the session, then you must continue searching for the error cause. It looks like the session sweeper thread somehow was duplicated, but how this happens is unclear to me without seeing your code. If you just create your own Scheduler instance, this should not happen. -- Christoph -- LogMeIn Rescue: Anywhere, Anytime Remote support for IT.

It's actually a race condition, and in fact most of the time it works on my test machine, but sometimes not. And it's not really a freeze, the server works properly, just doesn't respond to Ctrl-C any more, right? I also agree that a better fix would be to use a condition or event instead of the global flag. I'll work on that and plan to have a bugfix release this month. A couple of issues have already been fixed after 1.1, and I have one or two other open issues that I want to address.

It works great for me and if there are any real issues, please report and I'll be glad to fix them. I'm currently trying to debug a freeze problem that occur every 1 to 3 weeks.The python appServer process is completely frozen, and must be killed with -9.It doesn't respond to any signal, so I can't dump its stack, and really don't know the cause strace shows that python is waiting on a futex. Again, I don't think this is a problem with Webware itself. I have my Webware 1.1 apps running on many servers for months without restart. I still have some actions to do in my investigations like: - separating the custom radius server I made which is launched in the same process in several new threads. (I didn't know about the GIL at that time...) This could really be the problem. You should run it in a separate process. - reverting to webware 0.9 Don't do that. There have been many bugfixes and improvements in 1.x. I've seen that there is a WSGI adapter that connects to the appServer. Is it possible to wrap a webware application in a real WSGI handler? This would allow to use webware applications under modern servers like gevent (gunicorn) and why not google app engine. The threaded app server is no more adapted to modern web techniques. A gevent based appServer would be so great! libraries like gevent-zeromq and gevent-socketio would be so nice to have. Yes, the adapter needs a running appserver. This has also advantages, because it decouples your WSGI server from the application. But you're right, it would be nice to have an option to run Webware applications without the AppServer, directly wrapped as WSGI, so we could make use of existing non-threaded WSGI servers. Actually, I discussed these ideas already years ago on this mailing list. However, there was not so much feedback and I had not enough time to realize it, so these ideas were not realized so far. So my question to this mailing list would be: How many people are still interested in having a modernized Webware version? How backward compatible must it be? Would it be ok to change package and method names to make them comply with PEP8 or to change getter functions to properties or should it be as compatible as possible?

Re: [Webware-discuss] Automatic Session Save in Transaction.py
Hi Steve, thanks for the detailed write-up; I see the problem. The current session handling is really not ideal when you're using AJAX (which is no wonder since Webware has been designed before anybody even thought about that). IMHO the most simple solution would be to keep a dirty flag (set whenever __setitem__ or __delitem__ is called for the session) and then save the session only when the dirty flag has been set. This will also be good for performance. We could also add an AppConfig setting for manual saving (False by default to maintain backward compatibility). In this case, the dirty flag would not be set automatically, but by calling a save() method on the session. But I'm already seeing a problem with that approach: Since the lastAccessTime is stored along with the session, it will not get updated if the session is not saved, so the session will expire too early if the user does not do anything that alters the session. We could also keep a dirty set instead of a dirty flag. This set would contain all keys of the session for which the value has been changed or deleted. When the session store saves the session, it would then merge the current session values with the dirty set. This would require an additional session read operation, though. And it would be a pretty substantial change to the current session store(s). I'd rather avoid such drastic changes at least for the upcoming 1.1 version. -- Christoph -- Free Software Download: Index, Search Analyze Logs and other IT data in Real-Time with Splunk.

The session objects are not shared between threads in this case. So the simplest solution would be to keep a dirty flag and store the session only if that flag changed or when a save() method is called. I guess save() could actually be added as a synonym for storeSession() and in this method, the dirty flag should be reset of course. Not sure if we should make it the standard mode for the FileStore and the MemcacheStore, because it's not 100% backward compatible, particularly because the lastAccessTime will not be updated. Of course we could always update the lastAccessTime in case the session is not dirty, but this would require an additional read operation and decrease performance. -- Christoph -- What You Don't Know About Data Connectivity CAN Hurt You This paper provides an overview of data connectivity, details its effect on application quality, and explores various alternative solutions. http://p.sf.net/sfu/progress-d2d ___ Webware-discuss mailing list Webware-discuss@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/webware-discuss

When I start the appserver, it shows the thread handling the ThreadControl servlet, and 9 idle threads, as expected. Then after a while, the idle threads go down to 4, also as expected. Webware also also comes with a script stress.py in WebKit/Test/stress. After I tried a stress.py 500 30 30, I saw 19 idle threads, slowly phasing down to 4 again, again just as expected.

Instead of copying it manually, you can also use make install to install it into the Apache modules directory and activate the module in the Apache config. I tried ModPython which worked great with one app, but becomes schizophrenic if you have two applications including serving up the opposite app for a given URL or reporting a 404 if the other app doesn't have that path.

for Paste WebKit (http://pythonpaste.org/webkit/).
As you noticed it uses htmlform which is deprecated; you must use
htmlfill directly. You must also add a name=color attribute to the
checkboxes to make these work.
It seems your problem is that the formencode errors are now unicode, so
you must encode these. Here is how I got it working with the current
Webware (I simplified it a bit by not using Webware actions):
class form(Page):
schema = FormSchema()
def awake(self, trans):
Page.awake(self, trans)
try:
fields = self.request().fields()
if 'name' in fields:
fields = self.schema.to_python(fields, self)
else:
fields = self.getDefaults()
except formencode.Invalid, e:
errors = dict((k, v.encode('utf-8'))
for k, v in e.unpack_errors().iteritems())
else:
errors = None
self.rendered_form = formencode.htmlfill.render(form_template,
defaults=fields, errors=errors)
def writeContent(self):
self.write(page_style % self.rendered_form)
def getDefaults(self):
return dict(age='enter your age', color=['blue'])
Let me know how it works for you.
Btw, instead of using a schema, you could also embed the validation info
in the form template and use the SchemaBuilder to parse these.

I am very pleased to announce a beta release of Webware for Python 1.1, available for download from SourceForge (at http://downloads.sourceforge.net/webware/Webware-1.1b1.tar.gz).

It happens if you are using more than one Webware app server connecting to the same memcache, right? In that case we need to fetch the counter every time from memcache (which is currently not done) because the other appservers could have updated it, and that would be indeed a lot of overhead.

Can I use Webware for Python to create a Python web application in the Model-View-Controller design? (I already answered personally, but just for the record.) Webware provides an ORM-like plug-in called MiddleKit that supports MySQL, SQL Server and PostgreSQL, but not Oracle. But you can use SQL directly via the cxOracle module and the DBUtils plugin which provides a robust database connection pooling for Webware. You can also use Webware with other ORMs such as SQLAlchemy which support Oracle, but there is no special support for these in Webware. The core Webware component (WebKit) has View and Controller somewhat mixed, so it does not really enforce MVC architecture, but it's quite possible to write applications based on these patterns, see e.g. http://wiki.w4py.org/modelviewcontroller.html Using templating engines like Cheetah or the PSP or KidKit Webware plug-ins, you can separate the view even more from the controller. -- Christoph - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Webware-discuss mailing list Webware-discuss@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/webware-discuss

I had another look at the MiddleKit tests and found that the problems are all caused by the fact that newer MySQLdb versions have autocommit disabled by default. MiddleKit however (at least the whole test suite) assumes autocommit is switched on. I have now patched MySQLObjectStore so that autocommit is explicitly activated for all MySQLDB connections, including those coming from a connection pool. I have also added an autocommit flag to the storeArgs, so you can also still disable the autocommit if you like.

If a client loses its network connection (network cable unplugged, out of range of the wireless network, etc.), and then re-establishes the connection, all Oracle connections and cursors that were open become invalid. Trying to execute a statement with one of those cursors returns an ORA-03114 NOT CONNECTED TO ORACLE error, which causes cx_Oracle to raise an exception of class DatabaseError. However, SteadyDB only tries to recover from OperationlError and InternalError exceptions(SteadyDB.py, lines 238 and 338). Any chance that SteadyDB could be changed in future versions to also recover from DatabaseErrors? Or perhaps there could be a mechanism for advanced users to set what exception types SteadyDB tries to recover from? Should I submit this as a bug? DatabaseError is very unspecific: I think cx_Oracle should really raise an OperationalError instead. I have noted this problem and will try myself next time I come across Oracle again. Can you also double check if it's really a DatabaseError and maybe ask the cx_Oracle folks whether this is intended? I currently only see they raise InterfaceErrors which would also be a problem: http://cx-oracle.svn.sourceforge.net/viewvc/cx-oracle/trunk/Connection.c?view=markup Making the error classes configurable is also a good idea, but we need to find a good default set and and I'd also like to see cx_Oracle fixed since I think OperationlError is the only correct exception for connection loss (the InternalError was already a concession). -- Christoph - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.

So Webware invented a lot of the stuff itself we now take for granted, e.g. its own plugin-system. You're right, this is now an anachronism. I'm planning to make Webware more standard which involves some drastic changes. I wanted to start a discussion about this after Webware 1.0 is out. This must happen in a new version branch. The same for webware applications, the application context is not packageable, as it has direct pathnames to the webware installation. What about compatibility between applications and webware versions... Since version 0.9 or so, there are no absolute pathnames in Webware working dirs any more, except one single pointer to the Webware installation itself, so you can freely move an copy them. Concerning compatibility, the 1.0 branch will be stable and maintained with bugfixes for a very long time. -- Christoph - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Webware-discuss] First beta release of Webware for Python 1.0
The long-awaited final Webware 1.0 version will be released soon. Please take this as an opportunity to test Webware 1.0 beta 1 and let me know how the beta works for you and whether there are any problems, so that these can be fixed in the final release. If no problems are reported, there will be no beta or rc version before the final release any more.

Christoph Zwerschke schrieb: Ben Parker wrote: Calls to forward() will invoke the complete awake/respond/sleep cycle within the outer awake/respond/sleep cycle of the parent transaction. This means that if a servlet forwards a request to another servlet, then the session will be awakened twice and put to sleep twice (or more depending on the number of forward calls). This was causing some issues in our application because we use database sessions, but it would apply to anyone using the SessionFileStore as well. the transaction actually awake()s the session only if it does not exist, so it should not happen twice. Can you check that again? But I think you're right about sleep(). Transaction.awake() should really increase a counter if it does not awake the session because it already exists, and Transaction.sleep() should decrease the counter and send the session to sleep if it reaches zero. Would this solve your problem? I wrote nonsense in my first sentence. Of course the session is only awakened if it *exists*, i.e. when it was set with setSession() or implicitly created with session(). So you're right, in a nested transaction it will be awakened twice. I have now solved this in with a counter as you suggested: http://svn.w4py.org/Webware/trunk/WebKit/Transaction.py Let me know if this solves your problem. It will then go into Ww 1.0. -- Chris - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Webware-discuss] Fun with forms
Mark Phillips wrote: I am, at long last, playing around with using Webware for html pages that are information submission forms. I would like to create a dozen or so information request forms that are validated before being accepted. I can see that KidKit is loaded but I don't see how to invoke its examples. I tried adding line in Application.config... Contexts['KidKit'] = WebwarePath + '/KidKit' Don't do that. The KidKit plugin is loaded automatically if you have Kid installed, and you should see the KidKit example pages along with the other example pages e.g. for PSP. But KidKit is not the right thing for form validation anyway. Along the same lines, I was playing with Ian Bicking's FunFormKit. I read through the pages about FunFormKit and didn't find a comment as to where to place the files, so I placed the FunFormKit directory in a working directory using MakeAppWorkDir.py. It is at the same level as Main.py. I added this line to Application.config: Contexts['FunFormKit'] = 'FunFormKit/Examples' I think you are confusing Plug-Ins and Contexts. KidKit and FunFormKit are both examples of Webware Plug-Ins. They are usually installed directly in the Webware directory, at the same level as the WebKit directory (you can control which Plug-Ins are loaded from where with two AppServer.config settings). The Contexts usually only contain your actual Webware servlets. Concerning form creation and validation, you can try out FormKit, FunFormKit und FormEncode. A while ago I was planning to integrate FormKit back into Webware, or create a better replacement, but never found the time. -- Chris - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Webware-discuss] Session Issue
I will revert to the previous server, then try to reproduce the problem. I hope the session incompatibility will not show up again... Yes, you should check the new version on the old server and the old version on the new server to see whether it is an issue of the server or or Webware. I have 0.9.4 in production running on two servers for some time now, and haven't met any problems. Concerning the sessions, this may have to do with the more secure default cookie path for Webware. It will be probably using '/wk' now, while you had been using '/'. If you still experience problems with the cookies, you can set a fixed cookie path in 0.9.4, setting 'SessionCookiePath'. But the default setting should work fine normally. If your servers have different Python versions, check that the server has write access to create new .pyc files or recompile these. Please note that I will be offline for 3 weeks and cannot help with Webware during that time... -- Chris - This SF.net email is sponsored by: Splunk Inc.
