Shutting down ZServer
by Andrew M. Kuchling 08 Dec '99

08 Dec '99

We're experimenting with Zope 2.1 and FastCGI; this marks the first time I've seriously used ZServer, and I have a possibly silly question. An odd behaviour I've noticed is that 'Shutdown' on the Control Panel isn't shutting down Zope; while the usual SystemExit traceback is printed, the Zope process hangs around, preventing FastCGI from starting a new Zope server on the next request. Before I spend some time tracking this down, I want to be sure that this isn't expected behaviour; should ZServer be shut down differently, by some means other than the control panel? -- A.M.

Zope gets stuck
by Itamar Shtull-Trauring 08 Dec '99

08 Dec '99

stuck means infinite loop - won't respond to HTTP requests, although the monitor still works. I'm running http_load, with attempted 50 requests a second for 10 seconds on a computing intensive method (convert long article from structured text, do replace, split, replace, put back together - DTML and pythonmethods.) With 10 requests a second Zope does fine. 50 requests a sec against a simple method also works fine. While running http_load Zope does: 1999-12-08T12:29:45 ERROR(200) ZServer uncaptured python exception, closing channel <zhttp_channel connected 192.168.1.2:4243 at 85c6e58 channel#: 468 requests:1> (socket.error:(32, 'Broken pipe') [/home/zope/ZServer/medusa/asynchat.py|handle_read|80] [/home/zope/ZServer/medusa/http_server.py|recv|406] [/home/zope/ZServer/medusa/asyncore.py|recv|256]) ------ 1999-12-08T12:30:07 PROBLEM(100) ZServer Server accept() threw an exception ------ 1999-12-08T12:30:07 PROBLEM(100) ZServer Server accept() threw an exception . . etc. . ------ 1999-12-08T12:30:10 PROBLEM(100) ZServer Server accept() threw an exception ------ 1999-12-08T12:30:11 ERROR(200) ZServer uncaptured python exception, closing channel <zhttp_channel connected 192.168.1.2:4487 at 85c7038 channel#: 711 requests:1> (socket.error:(32, 'Broken pipe') [/home/zope/ZServer/medusa/asynchat.py|handle_read|80] [/home/zope/ZServer/medusa/http_server.py|recv|406] [/home/zope/ZServer/medusa/asyncore.py|recv|256]) I hit Ctrl-C, and get: Traceback (innermost last): File "/home/zope/z2.py", line 583, in ? asyncore.loop() File "/home/zope/ZServer/medusa/asyncore.py", line 107, in loop poll_fun (timeout) File "/home/zope/ZServer/medusa/asyncore.py", line 55, in poll (r,w,e) = select.select (r,w,e, timeout) KeyboardInterrupt Traceback (innermost last): File "/home/zope/z2.py", line 433, in ? zdaemon.run(sys.argv, os.path.join(INSTANCE_HOME, Zpid)) File "/home/zope/lib/python/zdaemon.py", line 208, in run p,s = os.waitpid(pid, 0) KeyboardInterrupt -- Itamar S.T. itamars(a)ibm.net

Re: [Zope] How to upgrade from 2.0 to 2.1 Zope

)This sounds like it is more suited for Zope-Dev at this point, thus the change) Stuart 'Zen' Bishop wrote: ... > IMHO there should definitly be a seperation of the Zope distribution > and site specific stuff (including /var).

These are just the ones I know of... Hmmm .. what if: One could have a central code repository, with the above directories being configurable. That is to say, what if the start script/Xope.cgi, could get the location of these directories at runtime, like an environment variable? This would allow (AFAIK) the central source, and individual (ie, per server) products. Certainly cuts down on disk usage :-) Comments? -- In flying I have learned that carelessness and overconfidence are usually far more dangerous than deliberately accepted risks. -- Wilbur Wright in a letter to his father, September 1900

RE: [Zope-dev] HTML rendering

Arrange for the module below to be imported, and you have an extra tag that does what you want. It removes spaces very agressively, possibly in some places that it shouldnt. Use it in dtml as: <dtml-unitws>Kill these spaces</dtml-unitws> from string import split, strip, join import DocumentTemplate.DT_Util from DocumentTemplate.DT_String import String class UnitWhitespaceTag: """ Removes redundant whitespace (not very conservatively) """ name='unitws' blockContinuations=() def __init__(self, blocks): tname, args, section = blocks[0] args = DocumentTemplate.DT_Util.parse_params(args) self.blocks = section.blocks def render(self,md): a = [] for line in split(DocumentTemplate.DT_Util.render_blocks(self.blocks, md),'\n'): line = strip(line) if line: b = [] for word in split(line,' '): b.append(strip(word)) a.append(join(b,' ')) return join(a,'\n') __call__=render String.commands['unitws']=UnitWhitespaceTag

In some time we will have a pluggable multi-format interface which lets you define your own behaviors for parsing and rendering of textual content. -Michel

Re: Eliminating forced HEAD/TITLE/BASE HREF - followup
by Tom Neff 07 Dec '99

I didn't see Jim Fulton's response until after posting my own workaround to the previous Digest. I am using Zope 2.1.0 beta 2 on FreeBSD 3.0, and it works great. Jim wrote: > If I create a page (in 2.1) I don't get them. When I read this I went back and tried to find out when it does and doesn't happen. If I create a new DTML Method called 'junk', the entire source of which is Hello world! i.e., no DTML tags or HTML tags or anything, just that string... then the HTTP output from ZServer (after the headers) is exactly as Jim describes: my source string sent back to me, with no embellishments. telnet my.machine 8080 GET /junk HTTP/1.0 HTTP/1.0 200 OK Server: Zope/Zope 2.1.0b2 (source release, python 1.5.2, linux2) ZServer/1.1b1 Date: Tue, 07 Dec 1999 17:00:19 GMT Connection: close Content-Type: text/plain Content-Length: 12 Hello world!Connection closed by foreign host. However, if I go back and change the source for 'junk' to read <B>Hello world!</B> then lo and behold, look what ZServer sends me: [earlier headers the same] Content-Length: 39 <html><head></head> <B>Hello world!</B>Connection closed by foreign host. In other words, if there is any apparent HTML in there, someone is deciding it needs some decent tags so the kids at school don't laugh. :) I think the <base href> tag is added if, in addition, your method is "index_html." I do not have the time today to research this very exhaustively.

Hi, We at ZDP thought other people also want to know how ZDP is doing... so here is the latest News... Weekly News of 1999/12/03 Not much activity at the moment on ZDP, but still some great news * Rik Hoekstra already wrote his 3rd part of changing contexts in Zope. He really needs feedback on these drafts... please give him a hand. * We received positive replies on our letter to the publishers, soon we'll put this information on the ZDP list * We've a new member, who's already writing late at night and who now wants to join ZDP, surely we don't have any problem to let him/her join the club... I don't tell you who he/she is, that's up to him/her :-) * Oh yes, I've put my old-website around Zope again on the web, you now can find it at : http://gallery.uunet.be/tom.deprez/Master See you all next week (I hope) Regards, Tom.
