Such are the risks of following the CVS very closely. ;) There is one thing cvs need BAD, a 'cvs unupdate' to revert a recently updated tree to it's previous state. I know this can be done on a file by file basis, but it would be nice to step a whole tree of code back one iteration. Any CVS Gods out there know the knack?

Threading deadlock in ZServer 1.1b1?
by Skip Montanaro 03 Jul '99

03 Jul '99

Has anyone encountered deadlocks in the threading code in ZServer 1.1b1? I do not use threads in my code and I can see no way to disable the thread code in ZServer. Attaching to the hung process produces the following nearly useless gdb traceback: #0 0x400a4bb4 in __syscall_sigsuspend () #1 0x400c675c in __DTOR_END__ () #2 0x40013ef3 in pthread_cond_wait () at condvar.c:148 #3 0x8061f82 in PyThread_acquire_lock () #4 0x80794fd in lock_PyThread_acquire_lock () #5 0x8053fad in call_builtin () #6 0x8053ec4 in PyEval_CallObjectWithKeywords () #7 0x8052f3d in eval_code2 () #8 0x8052dfd in eval_code2 () #9 0x80542d8 in call_function () #10 0x8053eba in PyEval_CallObjectWithKeywords () #11 0x8066f42 in PyInstance_New () #12 0x8053fc3 in call_builtin () #13 0x8053ec4 in PyEval_CallObjectWithKeywords () #14 0x807961a in t_bootstrap () #15 0x40014c56 in pthread_start_thread (arg=0xbf9ffd28) at manager.c:165 I tried using the trick Barry Warsaw posted recently about getting a Python traceback with the following gdb command: call PyRun_SimpleString("import sys, traceback; \ sys.stderr=open('/tmp/tb','w',0); traceback.print_stack()") but that invariably fails to produce anything. I will try building Python with -g so I can at least muck about in the C call stack, but I'm hoping someone has encountered this problem and has some suggestions. I saw nothing useful in the bugs reported for ZServer. (My wild-ass guess is that some client is behaving badly - perhaps the user pushes the stop button at the wrong time or the client crashes - which causes some infrequently executed exit path to be taken which doesn't release whatever lock has been acquired, but that's mere speculation at this point.) <stopped-in-scotia> Skip Montanaro | http://www.mojam.com/ skip(a)mojam.com | http://www.musi-cal.com/~skip/ 518-372-5583

For the ease of use during the creation of content using zope....I am looking into integrating a java based systax highlighting editor into the page editor of zope (ie...instead of...or as an option to...the text box used in a html form)..... The only version of zope that I have played with is the 1.XXXX series....I was wondering what has changed in 2.XXX (I will D/L a copy and have a look myself...just asking)........also...Does anyone here have any objections/suggestions for this project?

This could be fouling you. Well, I *think* I found the issue. I was adding this link to the bottom of a tree structure, and it appears it was taking it's ,,/ from the tree's base of PARENT[0]. So, just for grins, I changed the Tree's base to PARENTS[-1], and it seems to be working now. I will examine this further...

Upon trying to add a new folder in today's updated cvs, I get the following:  This happens regardless of options selected. Root folder obviously ;-) Just thought I would give a heads up in case someone has fixed it and I missed it somewhere. Bill

Folder Creation
by Jason Spisak 02 Jul '99

02 Jul '99

Just a heads up, As of 12:00 Pacfic Time Friday(Today) the CVS checkout won't allow the addition of folders. Traceback is: exceptions.TypeError Folder.py line 137 in manage_addFolder TypeError: too many arguments; expected 2, got 3. Also image display is broken. I try to view and image that uploads fine to Zope 1.10 and Zope 2.0.0a3 download inside the CVS version and I get a broken image. No traceback, just a broken image. Same is true for the image is uploaded in the ZClasses "Basic" Tab. Again, just a heads up. BTW it is good to be back working in Zope again. The Catalog is really changed since I last worked with it. Some great stuff going on! -- Jason Spisak webmaster(a)mtear.com

During the past 3 years, we have developed a killer web application in Python. So instead of keeping it closed source and having only a dozen customers, we give it away to get hundreds.

Yes. > Whats to stop a company such as mine to take Zope > and totally > bypass Digital Creations? Has such a thing happened before? Go ahead. You are welcome to use any part of Zope in your own product. In fact, we *want* you to do this. If you do, however, you must comply with the license: # 4. All advertising materials and documentation mentioning # features derived from or use of this software must display # the following acknowledgement: # # "This product includes software developed by Digital Creations # for use in the Z Object Publishing Environment # (http://www.zope.org/)" You could concievably use our software and not credit us and not tell us, but then you would have to deal with the snarling killer dogs that Hadar hires for his lawers. > > On a less related topic... is Frontier( or any of the > products listed > above) similar to Zope? > I've never used frontier, so I don't know. However, I do know that Frontier and Zope play well together because they speak a similar protocol, XML-RPC. Thus, Zope can work as a Frontier backend or vice versa. Feature cooperation of competing products is a far stronger model than feature competition. Even if Frontier competes with us, who cares? Our software is free, they are taking no money out of our pockets. And if their software is useful enough for people to pay for it, and it works very well with Zope, then the chances are higher that we will score another customer from that relationship. In fact, other than Frontier, this is a MAJOR flaw in the other products you listed. They don't work with anything but themselves, which is another way of saying they commoditize identical features between each other. They do the same thing, but in a completly incompatable way then their competetors in the interest of winning over customers and making money from the sale. This is a perfectly acceptable business model, but it's not ours; we feel ours (and in a similar way Frontier's) is stronger than that. -Michel > > -Joshua Zeidner > > > > > _______________________________________________________________ > Get Free Email and Do More On The Web.

Would you have said goodbye to Apache then? There are lots of new docs on the horizon. Amos and Pam are coordinating the new Zope Developers Guide, and soon there will be a *very* exciting announcment on Zope developer documentation that will be available in about six months. This has been a long standing problem, my first Zope app was when Zope was Principia and the source code was encrypted bytecode, the only way to figure out the API then was to bug Jim and use black-boxing techniques in a python interpreter (and yes, I had to walk uphill both ways to work every day too). Now that the source code is available and you get to know your way around, documentation is almost superfulous (that's what we tell ourselves at least, we realize that this is an unacceptable situation for most). There are two extrememly useful debugging tools, one is even documented. The Zope debugger and the medusa monitor client. The debugger lets you simulate a REQUEST to Zope and to enter the Python debugger at certain key breakpoints in the request path. cd to lib/python (make sure Zope is NOT running): [michel@aldous python]$ python1.5.2 Python 1.5.2 (#1, Apr 14 1999, 10:34:26) [GCC 2.7.2.3] on linux2 Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam >>> import Zope, ZPublisher >>> ZPublisher.Zope('') ... output from a request for '' which is the same as http://machine:port/ >>> ZPublisher.Zope('/manage', u='superuser:123', d=1) ... 'd=1' means enter the debugger immediatly, u='' is the userid and password to access the request (if it needs one). More information on the pyhton debugger can be found at http://www.python.org >>> ZPublisher.Zope('', t=1) ... runs the requst for '' 1000 times and prints the average time it takes to complete one request. Note that the above is for Zope 2.0 ONLY. If you are using Zope 1.10.2 it works ALMOST the same, except instead of saying 'Zope' everywhere, you say 'Main' like: >>> import Main, ZPublisher >>> ZPublisher.Main('') The medusa monitor client put you at a python prompt, RIGHT INSIDE ZOPE. This is so incredibly useful that sometimes I break into Tears Of Joy (tm) that Sam implimented this. Go to your top level directory and cd ZServer/medusa: [michel@aldous medusa]$ python1.5.2 monitor_client.py localhost 9999 Enter Password: XXXXX Python 1.5.2 (#1, Apr 14 1999, 10:34:26) [GCC 2.7.2.3] Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam Welcome to <secure_monitor_channel connected 127.0.0.1:2499 at 85f88c8> [Hint: try 'from __main__ import *'] >>> import Zope >>> x = Zope.app() >>> x <Application instance at 86dc130> >>> x.cat <ZCatalog instance at 86e90a0> >>> You are sitting right inside Zope. x=Zope.app() makes a connection to the database, at which point 'x' is the 'root folder' of your Zope install.
