[Phpwiki-talk] Bug? Pages unexpectedly deleated...

[Jeb B. <je...@oc...>]

Hi, I'm running phpwiki 1.2.0 at http://buyorganic.org/live
Overall, it's really cool.  However, I have seen some unexpected
behavior with pages being accidentially deleated when trying to edit.
I was watching the Apache log while it happened once, so will show the 
relevant log entries below, as I explain the process...

207.135.238.21 - - [09/Mar/2001:10:08:53 -0800] "GET
/live?MountainPeoplesOrder HTTP/1.0" 200 5937
207.135.238.21 - - [09/Mar/2001:10:09:05 -0800] "GET
/live?edit=MountainPeoplesOrder HTTP/1.0" 200 5168

[Originally GET and edit of page.]

63.237.193.173 - - [09/Mar/2001:10:09:30 -0800] "GET
/wiki/admin.php?MountainPeoplesOrder HTTP/1.1" 200 6093

[I check that it's still there at this point.]

207.135.238.21 - - [09/Mar/2001:10:13:43 -0800] "POST /live HTTP/1.0"
200 5614 "http://buyorganic.org/live?edit=MountainPeoplesOrder"
63.237.193.173 - - [09/Mar/2001:10:14:03 -0800] "GET
/wiki/admin.php?MountainPeoplesOrder HTTP/1.1" 200 2320

User posts edit, and gets 5614 bytes response showing success...
I reload, and the page ss gone! (2320 bytes is new page template)

63.237.193.173 - - [09/Mar/2001:10:19:49 -0800] "GET
/wiki/admin.php?diff=MountainPeoplesOrder HTTP/1.1" 200 838

I check diff, which shows nothing in the database.  (I think it should
diff an empty pages against the archived copy.  Similarly, I think 
editing a deleated page with a copy in the archive should present the 
option to edit the archive copy...)

207.135.238.21 - - [09/Mar/2001:10:20:03 -0800] "POST /live HTTP/1.0"
200 5724 "http://buyorganic.org/live?edit=MountainPeoplesOrder"
63.237.193.173 - - [09/Mar/2001:10:20:57 -0800] "GET
/wiki/admin.php?MountainPeoplesOrder HTTP/1.1" 200 5655

I walked her through going Back, copying the text (sent to me as email)
and Saving again.  This time it worked(!!!) even though I expected
it to warn her that she was editing a previous copy, as I've seen when
going back before without reloading.

So, the page was unexpectedly lost.  Then, it was recovered by 
effectively posting a first edit to an empty page (which happened to 
luckily be in the browser cache).

The following is a possible clue, which I'm also confused about...
I did a 'dump serialized pages' to backup, and here is partial output:

SandBox ... 304 bytes written
MountainPeoplesOrderr ... 5 bytes written
MountainPeoplesOrderr ... 5 bytes written
MountainPeoplesOrderr ... 5 bytes written
MountainPeoplesOrder ... 3785 bytes written
HowToUseWiki ... 2403 bytes written

What are those three 5 byte pages with an extra 'r'??  They are not 
pages in the site database.  In fact, the first time I did the dump,
there was only one of these bogus entries in the output.  Since then, 
the page has been  accidentially deleated twice more.  So, I'm thinking 
these  records might be added each time the version is set back to 1 
(after a  page is deleated).

Of course, I plan to study the code to figure out exactly why this is
happening, but if anyone has ideas, I'd appreciate any clues.

Thanks!
