ZServerSSL deadlocking
by Dave Cinege 31 Jan '05

31 Jan '05

I'm seeing an issue, that (I'm pretty sure) is limited to ZServerSSL for m2c 0.13. I'm using Zope 2.7.4, Python 2.3.4, Linux 2.4.28 and Debian sid. My application is an appliance that I use Zope to mainly handle authentication, and the content is generated by my external methods, which deal with a mysql DB. Clients are directly connected to the LAN, and the amount of requests doesn't really exceed 1 per 3 seconds. All requests (are to) go through https. I consider this a fairly light load. It seems that after a few hours or days of uptime Zope will just cease to serve content. It's sporadic. Today it happened on a unit at a customers location. I was able to ssh in and see it first hand. If I restarted Zope, it MIGHT come back to life. But would only serve a few pages and then dead lock again. I narrowed it down to SSL as I would restart restart zope, and telnet-ssl 127.0.0.1 80 HEAD / HTTP/1.0 And it would return fine. But the first attempt to the same on port 443 would deadlock, and no requests would come back on 80. (I can reconnect to 80, but it never replies) What is REALLY strange is I know if I had rebooted the unit it would have went back to normal. But in what ever state things were in, by COMPLETELY killing the zope application and restarting it would deadlock very quickly upon SSL connect. After I saw this, I removed the HTTPS section from the zope.conf and allowed clients to connect with http. So far, it's seems ZServerSSL is the cause of this issue. Now to make matters worse: I see nothing in the logs before the deadlock. No dmesg output. No syslog output. Free output looks fine. PS output looks fine I see no active memory leaks The the very strange thing is if I reboot the unit, it would work fine again, for an indeterminable amount of time. One thought that has come to mind is it's running the random pool dry and waiting...but m2crypto draws from /dev/urandom, right? So that shouldn't be an issue. Any ideas?

I have tried simply adding the code to my httpd.conf file but unfortunatly it hasn't worked. I have included my httpd.conf file below. I am sure mod_proxy is installed and working fine.

Acquisition - I don't get it
by Jan Bruvoll 31 Jan '05

31 Jan '05

Hi there, I've been struggling with something that must be very basic, but I just don't get it. Hopefully, there's somebody out there who could enlighten me a little... I have this site hierarchy, something like this: /top /top/section1/ /top/section1/chapter1 /top/section1/chapter1/paragraph1 /top/section1/chapter1/paragraph2 /top/section1/chapter2 /top/section1/chapter2/paragraph1 /top/section2/ /top/section2/chapter1 /top/section2/chapter1/paragraph1 etc. These are all folders with an index_html inside them. The template will have, among other things, a site title image, a section title image, and a page title image for each page. The idea here is to be able to create a folder img/ at appropriate levels of this hierarchy and use images section_title.gif, chapter_title.gif, page_title.gif, etc. This might be where I've misunderstood everything, but I was hoping to do something like this: <img src="dummy.gif" class="title-img" tal:define="image here/img/section_title.gif" tal:attributes="src image/absolute_url" /> If for instance looking at one of the paragraph pages, the template would then, in my perfect world, start looking for an "img/" folder at the current level, and within it a file named "section_title.gif", and if it does not find it, it will try again one level up in the hierarchy, until it then finds the section_title.gif in the folder /top/section1/img/section_title.gif. Same goes for the other images, but they would "hit" further down in the hierarchy so that I could effectively let a "closer" image override one with the same name, but further up. Have I got it completely wrong? Is my thinking right, but my syntax wrong? Haven't been able to get anywhere on this - all documentation I can find gives hints and pointers, but I'm still stuck... Any help & comments highly appreciated! Best regards Jan

Hi, I've installed the webmail product v4.3.1 on zope 2.7 but I can't see all the options as described in the readme, I can't see any icons also. when I call the webmail page at the top of the page I see this: "Il n y a pas de carnet d adresse,cliquez sur l icone -Contact- pour en creer un" but I don't know what it is. I'm quite new to zope, i find it fantastic. I'm traing to unterstand how can I automatically add the webmail to every new registered user, is this possible? How can I set automatically the username and the password which the user has choosed by registering in the property of the webmail modul I'm looking for a good zope programmer for the costruction of a webmail portal. Interested people can contact me at javier(a)callwayonline.de. Regards. Xaver

[Fwd: TALs Expressions]
by Brian Brinegar 31 Jan '05

31 Jan '05

Please explain, I've got this page template, with an empty title. <h2 tal:condition="template/title">Has a Title</h2> <h2 tal:condition="template/id">Has an Id</h2> <h2 tal:condition="template/title | template/id">Has a Title or Id</h2> The rendered out put is: <h2>Has an Id</h2> So... <h2 tal:condition="template/title">Has a Title</h2> The tag is omitted because there is no title, which is what I would expect (empty string evaluates to false). <h2 tal:condition="template/id">Has an Id</h2> The tag is included because there is an Id, again what I would expect. <h2 tal:condition="template/title | template/id">Has a Title or Id</h2> The tag is omitted (what???) but there is an id, I would expect this to evaluate to true (false | true == true). (In fact.. anything to the right of the pipe is not even accessed/called) Is there something wrong in my thinking? -Brian

Well, it looks like you are trying to import an object but Zope can not find the file in it's "Import" directory. (by default, objects get exported to the "var" directory, so you then have to move them to the "Import" directory to import them back) Pascal -----Message d'origine----- De : zope-bounces(a)zope.org [mailto:zope-bounces@zope.org]De la part de Lopez Melvin Envoyé : lundi 31 janvier 2005 01:09 À : zope(a)zope.org Objet : [Zope] Module ZPublisher.Publish Please help me with this issue.

DateTime.strftime problem
by Ron Bickers 31 Jan '05

31 Jan '05

I'm running Zope 2.7.4 and I'm trying to format the current time in the format "yyyymmddhhmmssZ" (that is with a timezone of UTC), but I can't do it. The DateTime API says that "A DateTime object's methods return values based on the timezone context." This appares to be the case for all except strftime(). For example (my local timezone is US/Eastern): now = DateTime('US/Pacific') now.pCommonZ() Jan. 30, 2005 12:35 am US/Pacific now.rfc822() Sun, 30 Jan 2005 00:35:58 -0800 now.strftime('%Y/%m/%d %H:%M:%S %Z') 2005/01/30 03:35:58 EST It looks like Collector Bug 1127 (http://zope.org/Collectors/Zope/1127/) changed strftime() to always work in the local timezone, instead of always working in GMT as it did before. But shouldn't it respect the timezone of the DateTime object as do the other methods? Is this a bug? -- Ron

Migration of Zope 2.2.3 Installation
by Segedunum 31 Jan '05

31 Jan '05

Hi All, I've got a server that is running Zope 2.2.3 (currently using Python 1.5) that I need to migrate, and I'd appreciate some advice. Given some cyclic dependencies on this system we can't upgrade Zope straight away, but we need to upgrade the rest of the system which indirectly entails updating to Python 2.4 which is unavoidable. Does Zope 2.2.3 depend tightly on Python 1.5, or could it run under 2.4? If not I'll have to think about some kind of slotted install and move over. Just wondering if there any issues people have encountered in upgrading pretty old Zope servers that may be helpful, such as migrating the Data.fs (this is pretty large). Thanks, David

Hi, I have a problem where the zope instance I have been running has suddenly gone down. I seems that zope processes are alive, but is just not responding to http requests.
