Python script to export Zwiki pages to text output --Win Myint Aung, Thu, 01 Mar 2007 08:50:54 +0000 reply

I looking the python script that can export Zwiki contents in Zope to text output. please help me. news --Simon Michael, Wed, 07 Mar 2007 22:13:23 +0000 reply

An update on the* server for 2007/3/7:

Uptime troubles and investigations continue, and there have been significant outages as I haven't always been able to respond quickly. Thanks for your patience; we are making progress.

I have been watching the server processes and tuning various things. Sascha Welter implemented http conditional-get handling for zwiki, and also configured httpcaches for several of the (dynamic) front pages. We have reduced cpu load a lot, and made loading of previously-visited pages a lot more snappy!

(Note there is an open issue with conditional-get: Firefox and Mozilla users with default settings will often have to reload after an edit to see the changes. We have some ideas to prevent this, until then I might have to revert this feature.)

Edit operations, especially those touching many pages, can still be rather slow as we are still memory-constrained (~250M quota). The server is currently running two zope threads with cache-size 3000. When it exceeds quota (be it through normal growth or memory leak) it is restarted; this is still happening one or more times per day. Restarting and warming up the caches is quite slow (can be 5-10 minutes if I'm not mistaken).

I have gone from 7-day to 2-day nightly packs to keep zodb size around the 1G mark (and within the 8G disk quota).

Martijn Faassen is pursuing a possible new, beefier hosting situation.

Thanks also to Sascha Welter, Michael Haubenwallner, Christian Theune and anyone else I've forgotten, for dropping by #zwiki on and helping to troubleshoot and fix issues.

Cheers! - Simon

PS I seem to have too many places to post such news: - zope-web list/gmane.comp.web.zope.websites newsgroup - - - - I will probably pick just the first 2 or 3 henceforth.

They could work around the problem, by making their browser behave like all the others with a config change... it's what most web apps tell their users to do. We'll find out if we can give them a better service.

I'm thinking about hacking in a general tagging field -- something more flexible than subtopics or badges -- and am wondering if you have any general advice, especially re: hooking in to the catalog. Thanks.

adding tagging --betabug, Fri, 09 Mar 2007 09:17:12 +0000 reply

jmax, your description reads a bit vague to me, maybe you have to sketch out a little bit more what exactly you want to achieve. The term "tagging" is used for a number of related things. If your description gets longer - and if you want - make a new page, so discussion could get a bit more focussed there.

I'd LOVE that feature! See: ZWikiTaggingDiscussion

In the past I've been shot-down by badges and keyword searches seemingly meeting 80% of user needs, but tagsonomy sites seem to have flourished and not fizzled, so I think you're on to something. The folks who want to easily add a sortable field to ZwikiIssueTracker will also thank you.

adding tagging --betabug, Sat, 10 Mar 2007 08:27:11 +0000 reply

> I'd LOVE that feature

Uhmm, what feature? I have yet to see some kind of description of what exactly you want. I don't know about sm or anybody else hacking on Zwiki, but if I am trying to implement something, I want to have an idea what it's going to look like. So there is a field somewhere? Then what? Are the contents of the field simply searched with the search form? Are they used for anything else? I can't read anybody's mind, so people who want a feature will have to give details.

Based on detailed descriptions of a candidate feature programmers can decide on how hard it's gonna be to do it, if it's worth it, how to implement it, all that stuff. So far all I see is a war of the buzzwords.

adding tagging --jmax, Sat, 10 Mar 2007 15:34:19 +0000 reply

OK, here's how I see it, as the simplest possible implementation: On each page is a single input field called "tag this page", which can be used to add a tag phrase to a list of tags already added to that page (or empty, if none so far). That's basically it for the UI. The tags added to each page, though, need to go into the ZWiki catalog so that they can be searched. I think it would be an adequate first step to integrate this with the existing search, but there's an obvious use case for making it a separate search (i.e. with its own UI) from the existing one.

Here's the rationale: trying to do tagging by organizing existing pages (using the parent/subtopic hierarchy) means you have to actually HAVE an existing wiki page in order to use that as a categorizing element. A free-form tagging facility would allow people to put in arbitrary terms which may at some later date become wiki pages (or not). Using wiki badges is a little better in this regard, but it's a bit of a kludge and doesn't integrate nicely into the UI, unless you're prepared to turn the wiki inside out and make backlinks into a first class navigational element.

So, simplest possible thing: add one field, which goes to a list property on each page, and catalog them so they come up in the searches.

Not to be a damp squib, I'm not too enthusiastic about this, because

You could make the existing wiki-ish tagging more accessible through better UI, maybe ?

how to add network drive --birb, Fri, 16 Mar 2007 13:05:20 +0000 reply

Hi How can I add a link to a windows network drive (share)


how to add network drive --EmmaLaurijssens, Fri, 16 Mar 2007 16:08:02 +0000 reply

Client-side: use the 'file://servername/sharename/pathname' format, or 'file:///drive:/pathname'.

Server-side: you need an extra product to do that. If you have Plone, PloneLocalFolderNG? is the best choice, otherwise you could try to use something like LocalFS. I can't guarantee that they work with UNC paths.

Add zwiki page to the wrong location --EmmaLaurijssens, Fri, 16 Mar 2007 17:55:52 +0000 reply

Parenting has nothing to do with folders in Plone. All wiki pages reside in the same folders, zwiki keeps track of the page hierarchy internally. If you want to create subtopics, you need to use the controls below the comment area, like on the bottom of this page.

If you have put your wiki in a Plone folder, the 'create' button might be missing due to issue #1220. Make sure you have the 'ZWiki: Add pages' permission checked in the ZMI.

I can't seem to find the answer to this. I'm using Zwiki in a Plone site. I want a footnote to be created, so I use [1]?_ as described in the documentation. Where I want the footnote to appear, I use .. [1]?

This seems to work, in that the footnote marker will link to the actual footnote. However, zwiki puts a ? next to the footnote, as it thinks I'm specifying a Zwiki page. I'm using reSt. Any ideas on how to fix this?

birb, no need to convert anything if you don't want to. You can put your existing html and plaintext files directly into Zwiki, without changing them. The plaintext pages can also be put into RST type pages and can be enhanced with minimal work effort. You can then work on growing your wiki from the existing files.

MaildropHost? install --Simon Michael, Sat, 24 Mar 2007 05:59:02 +0000 reply

> any chance of a little writeup of your experience setting MaildropHost? up?

Summary: it wasn't easy; it seems to be working well now. I haven't reported bugs; here's a start at least.

I installed . I couldn't figure out the svn checkout command so downloaded the 1.19 tarball.

There is a helper daemon in MaildropHost?/maildrop; setting this up was a bear. I tried putting things in a number of different places. There are a number of pieces to configure and they handle paths inconsistently. I think I might have fixed/hard-coded a path or two, but since this isn't an svn checkout I've forgotten where.

The daemon died silently several times a day. I didn't get around to playing with the debug flag to find out why. When that happened the file remains and maildropctl start doesn't work, but I found that maildropctl restart does reliably work. So I run that hourly with cron and that takes care of keeping maildrop running. (I researched daemontools, supervisor2 etc. but haven't needed them). I still run a checkmaildrop script to alert me if it finds the process missing.

I haven't seen this yet, but in past experience many kinds of unexpected content in emails caused it to break, which led to undelivered mail backing up in the queue. The checkmaildropqueue script will alert me when/if that happens.

Here's the final setup that works for me. I installed:


I added (for an ubuntu server):

/etc/rc0.d/K21zopemaildropctl -> ../init.d/zopemaildropctl
/etc/rc1.d/K21zopemaildropctl -> ../init.d/zopemaildropctl
/etc/rc2.d/S21zopemaildropctl -> ../init.d/zopemaildropctl
/etc/rc3.d/S21zopemaildropctl -> ../init.d/zopemaildropctl
/etc/rc4.d/S21zopemaildropctl -> ../init.d/zopemaildropctl
/etc/rc5.d/S21zopemaildropctl -> ../init.d/zopemaildropctl
/etc/rc6.d/K21zopemaildropctl -> ../init.d/zopemaildropctl
/usr/local/bin/maildropctl -> /zopeproducts/MaildropHost/maildrop/bin/maildropctl

and these monitor scripts:

# /usr/local/bin/checkmaildrop - check that MaildropHost's is running
ps auxww |grep -v grep |grep -q || (
 echo WARNING! is not running, please investigate.)

# /usr/local/bin/checkmaildropqueue - check for stale messages in MaildropHosts/maildrop's outbox
# (usually a couple fail delivery due to bad addresses and can be deleted,
# XXX better if these could be converted to bounces)
find $QUEUE -mindepth 1 -maxdepth 1 -type f -cmin +160 |grep -q '' && (
 echo WARNING! mail in $QUEUE undelivered after two hours, please investigate.

and these rules in /etc/crontab:

# keep zope maildrop process up
0 *     * * *   root    maildropctl restart

# report a missing maildrop process (just for interest, the above will fix it)
55 *     * * *   root    checkmaildrop

# report stale undelivered maildrop messages
55 *     * * *   root    checkmaildropqueue

My proxy seems to be bugging me, POSTing? large text pages fails for some reason. I wanted to add this to the "upgrade" section of the ReleaseNotes, but I can't, though I think it's important:

  • The standard issuetracker and filterissues pages now support sorting on issue name and reverse sorting (#14). For this to work, the catalog needs to be extended. Be sure to visit somepage/!upgradeAll and somepage/!setupTracker, or both pages will break.
  • If you have customized IssueTracker and/or FilterIssues pages, you might want to replace them with the standard pages. To do this, carefully review the changes you made. Make backup copies if you wish. Then, delete both pages, and upgrade with somepage/!upgradeAll and somepage/!setupTracker?pages=1.
