Description

If Xapian is switched on AND if MoinMoin is running on an mod_wsgi enabled apache server than after every page save action I get one of these effects:

• either the message "You already saved the page!" or
• I only see a completely white page. If after that I remove the string "#preview" out of the browser's address line, I see the page with the changes in it I saved before.

Steps to reproduce

• Install MoinMoin 1.9.2 on a Windows XP machine

• switch xapian on
• build the index

• start MoinMoin through Mod_WSGI enabled apache webserver

• edit a page and save it

You (at least me) will see a message like this: "You already saved that page!" or you might only see a totally white page in your browser.

Switch Xapian

Example

Component selection

• editpage.py ???

Workaround

If I run MoinMoin in standalone mode, everything works as usual.

Discussion

Interesting: If I load the page with the internet explorer, I see edit conflicts after saving a page with changes. It seems as if Moin for some reason gets two post messages.

My apache logfile contains this after saving changes on a page in Internet Explorer:

xxxxxx - - [04/Mar/2010:16:35:28 +0100] "POST /xxxxxxxxx/%C3%9Cbersicht HTTP/1.1" 200 17538
xxxxxx  - - [04/Mar/2010:16:35:29 +0100] "GET /moin_static192/common/moinmoin.png HTTP/1.1" 403 1206
xxxxxx  - - [04/Mar/2010:16:35:30 +0100] "GET /xxxxxxxxx/%C3%9Cbersicht?action=edit&editor=gui HTTP/1.1" 200 32278
xxxxxx  - - [04/Mar/2010:16:35:41 +0100] "POST /xxxxxxxx/%C3%9Cbersicht HTTP/1.1" 200 35905
xxxxxx  - - [04/Mar/2010:16:35:44 +0100] "POST /xxxxxxxx/%C3%9Cbersicht HTTP/1.1" 200 17546
xxxxxx  - - [04/Mar/2010:16:35:45 +0100] "GET /moin_static192/common/moinmoin.png HTTP/1.1" 403 1206

But this doesn't happen always. Normally also with Internet Explorer (I normally use Firefox) I get the message "You already saved the page!".
