asyncore+Zope: different behavior in Windows and Linux
by Dmitry Dembinsky 14 Aug '03

14 Aug '03

Hello Zopers, I currently develop a Zope product, part of which will handle incoming TCP connections. To avoid multithreading, I intended to use asyncore module. ZServer already runs asyncore.loop(), so the idea was to put a server socket to a global asyncore.socket_map to have it checked for network events in a main ZServer loop and trigger overriden handle_* methods. To prove the concept, I created a very small test product (see the code below). Outside of Zope the code works fine on both Linux and Windows When running as Zope product it still works on Windows, but on Linux causes Zope to crash with the following traceback: ------------------------------------------------------------- Traceback (most recent call last): File "/usr/local/zope/z2.py", line 910, in ? asyncore.loop() File "/usr/local/zope/lib/python/ThreadedAsync/LoopCallback.py", line 150, in loop poll_fun(timeout, map) File "/usr/local/zope/lib/python/ThreadedAsync/LoopCallback.py", line 102, in poll r, w, e = select.select(r, w, e, timeout) select.error: (9, 'Bad file descriptor') ------------------------------------------------------------- My guess is that somehow, closed socket descriptor is not removed from the socket_map causing select() function to fail. (In this case I assume that there's a problem with Zserver) I searched bug collector and mail archives but didn't find any relevant information. Any ideas, please? My working environment: ------------------- Windows: OS: Windows XP Profesional SP1 Zope Version: (Zope 2.6.1 (binary release, python 2.1, win32-x86), python 2.1.3, win32) Python Version: 2.1.3 (#35, Apr 8 2002, 17:47:50) [MSC 32 bit (Intel)] Linux: OS: RedHat 7.2, kernel 2.4.20-19.7 Zope Version: (Zope 2.6.1 (binary release, python 2.1, linux2-x86), python 2.1.3, linux2) Python Version: 2.1.3 (#1, Sep 19 2002, 13:15:46) [GCC egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)] Below is the code of the test product: File __init__.py: -------------------------------------------------------------- import socket import asyncore class AsyncTestDispatcher( asyncore.dispatcher ): def start ( self ): self.create_socket( socket.AF_INET, socket.SOCK_STREAM ) tAddr = ( '0.0.0.0', 1234 ) self.bind( tAddr ) self.listen( 1 ) print self.__class__.__name__, "listening on %s:%d" % tAddr def stop ( self ): self.close() print self.__class__.__name__, "stopped" _g_oDisp = None def start (): print 'AsyncTest: starting' global _g_oDisp _g_oDisp = AsyncTestDispatcher() _g_oDisp.start () def stop(): print 'AsyncTest: stopping' global _g_oDisp _g_oDisp.stop() _g_oDisp = None # Zope staff __roles__ = None __allow_access_to_unprotected_subobjects__ = 1 def initialize( context ): print 'AsyncTest initialized' -------------------------------------------------------------- I put AsyncTest in a Products directory within my Zope installation, started Zope and created 2 python scripts via ZMI: asyncstart: -------------------------------------------------------------- from Products.AsyncTest import start start () print "AsyncTest started" return printed -------------------------------------------------------------- asyncstop: -------------------------------------------------------------- from Products.AsyncTest import stop stop () print "AsyncTest stopped" return printed -------------------------------------------------------------- Then I run asyncstart and asyncstop number of times Usually the crash happened on the first or the second iteration, always in stop() function: start -> stop -> crash (during stop) start -> stop -> start -> stop -> crash (during stop) in a rare cases there were 3-4 times before the crash Thanks in advance, Dmitry

RE: [Zope] Need help with ImageMagick or PIL with CMFPhoto for ph oto resize
by Meilicke, Scott 14 Aug '03

14 Aug '03

Hmm, that I don't know. I am cc'ing the list - maybe someone else does. I have always used Photo 1.2.3, and CMFPhoto only just to 'have a look see'. When I uploaded a bmp, Photo 1.2.3 would not resize it, perhaps the same is true of CMFPhoto. Photo would resize a jpg. Seems like the thing to do is install jpg support for imagemagick. Perhaps bypass the Redhat version and install imagemagick from source? Scott -----Original Message----- From: Jim Barbara [mailto:jbarbara11@yahoo.com] Sent: Thursday, August 14, 2003 6:36 AM To: Meilicke, Scott Subject: RE: [Zope] Need help with ImageMagick or PIL with CMFPhoto for ph oto resize I found out that it's just the jpg support that is not installed....so, I am able to do the convert with a bmp file. Now then, my next question/issue that you might be able to help me is with Zope and Plone. Since I can use the command line "convert -resize" a bmp file, I would figure that I can go to my Plone site and add a bmp file as a Photo object and then view the different sizes. However, I can only see the Photo (or bmp) in its original size. This tells me that Plone/Zope/Python does not "know" to use ImageMagick as the engine to use for resizing. Is there another tweak I must do to get my site to use ImageMagick? --Jim --- "Meilicke, Scott" <scott.meilicke(a)intp.com> wrote: > sounds like imagemagick isn't installed correctly... > I can't help you > there, unfortunately. > > Scott > > -----Original Message----- > From: Jim Barbara [mailto:jbarbara11@yahoo.com] > Sent: Wednesday, August 13, 2003 11:16 AM > To: Meilicke, Scott > Subject: RE: [Zope] Need help with ImageMagick or > PIL with CMFPhoto for > ph oto resize > > > Yes, I did try the convert after copying a jpg to my > tmp folder and got the following results: > > [root@localhost tmp]# convert Snowmen_Rabbit.jpg > Snowmen_Rabbit.gif > convert: No decode delegate for this image format > (Snowmen_Rabbit.jpg). > > --Jim > --- "Meilicke, Scott" <scott.meilicke(a)intp.com> > wrote: > > Have you tried ImageMagick from the command line? > > Something like > > > > convert -g 500x500 originalimage.jpg > > > > This will resize originalimage.jpg to be 500 px > max > > high or wide.

I'm using this code to try and get a user's password. from AccessControl import getSecurityManager request = context.REQUEST user = getSecurityManager().getUser() curpas = user._getPassword() but this gives me an error because i can't run a method that has a '_' in it's name. How do i then get a user's password? It would be nice to be able to mail people's password if they forget it :)

I recently set up a widget to email files from a localFS directory and it was working well for a few weeks.. However, suddenly it stopped working. I had made some changes in permissions recently, but I undo-ed them and the problem still occurs.. Where before I would have a PDF attachment, now I simply get a file with a PDF extension with one line, the name of the file that was supposed to be sent.. I've been trying to figure this out for hours.. Here is the code which was working before.. _____cut here_______ <dtml-call "REQUEST.set('fileid',_['theuserid']+'.pdf')"> <dtml-sendmail mailhost=mailhost Mailfrom="pdfsender(a)msri.org" Subject=" PDF to Proof"> To: &dtml.missing-EMAIL; <dtml-mime type=text/plain encode=7bit> Attached is the document you requested for proofing. <dtml-boundary name=proof.pdf type=application/pdf disposition=attachment encode=base64><dtml-with mylocalfs><dtml-with pdffiles><dtml-with FinishedFolder><dtml-var expr="_['fileid']"></dtml-with></dtml-with></dtml-with></dtml-mime></dtml-sendmail> Please check your email for it in a few minutes. ______________________ Thank you for any suggestions... -Chris

Need help with ImageMagick or PIL with CMFPhoto for photo resize
by Jim Barbara 13 Aug '03

13 Aug '03

I am using: Zope 2.6.1 Plone 1.0.1 CMF 1.3 I can add a CMFPhotoAlbum as well as a CMFPhoto on my Plone site. I want to be able to view the photo sized differently than the Original Size. I tried to install ImageMagick using the rpm for Redhat 9 (i386). Since it asked for a lot of XFree86 modules, I used the -nodeps option and it seemed to install just fine. However, I still cannot resize the photos. I am a newbie but I am learning. Could you please help me? Thanks, Jim Barbara __________________________________ Do you Yahoo!? Yahoo!

RevisionManager
by Robert Jean 13 Aug '03

13 Aug '03

Hello: I have recently tested RevisionManager 1.3.2 on Windows. RevisionManager integrates Zope with the versioning system CVS. Apparently, the primary target of this product is UNIX, but the product author says that some people have reported using it successfully on Windows. I would be very interested to hear from these people, because my experience shows a different picture. Also, if some people have run into problems on UNIX as well, I would love to hear from them. On Windows, IMHO, RevisionManager qualifies for a �pre-beta� status, at least at the functional point of view. But there is substantial work behind it, and fixing it might not require too much effort. Therefore, I would be delighted if someone who is experienced (maybe Philipp, the product author) could direct the effort. I would be happy to contribute. Basically, I can sometimes import / check in / checkout to / from a remote CVS repository using pserver. But: 1) GIF and JPEG images will default to the "File" type. Regardless of changing the file type to "Image" or keeping it to "File", the image will be corrupted (the file always has 462 bytes). Importing images reports an error "Error Type: AttributeError, Error Value: content_type" error). But the file goes to the repository anyway and can be retrieved uncorrupted with the CVS command line tool. So, something must go wrong when the image file is imported into the ZODB. 2) Even more worrying, I often get KeyError and AttributeError errors when manipulating objects of any type (DTML methods, files, ...). After that, the object becomes unusable. I think that RevisionManager is the source of these problems because with the CVS command line, everything works smoothly. 3) I have a problem when importing ZSQL methods, but it might very well have nothing to do with the product. It is maybe due to the dependency of the method on another object such as a connection. Maybe the same type of problem we face when importing objects in zexp format. Also, I have observed is that the path to the CVS executable must not contain any space, and quotes will not help (e.g. "c:\program files\cvsnt\cvs.exe" will result in "c:\program not found"). There are probably still a lot of issues, but there are the ones I am facing now. Robert __________________________________ Do you Yahoo!? Yahoo!
