[Moin-user] Sourceforge, backup, "Page could not get locked. Missing 'current' file?"

[Favre-Nicolin Vincent]

	Hi all,

  I setup a moinmoin wiki on sourceforge (at 
http://objcryst.sf.net/cgi-bin/moin.cgi). As apparently many other, the data 
directories (world-writable) were deleted on 20050831.
  I used my rsync backup to bring back the wiki online, no problem. But when I 
tried modifying a page, I got the (infamous ?) error:
"Page could not get locked. Missing 'current' file ?"

  At first I thought it was the file permissions but evrything was 
world-writable, so that was not it. After some time I found the actual 
problem, which was coming from the MoinEditorBackup pages, which are stored 
whenever you edit a new page in the directory: 
data/pages/YourWikiUserName(2f)MoinEditorBackup 

   Somewhere in PageEditor._write_file moinmoin tries to change the 
permissions and got booted.

   Bottom line: when recovering a backup, do *not* copy the 
data/pages/YourWikiUserName(2f)MoinEditorBackup directories...

   Maybe this should be added to the "Page could not get locked" FAQ in 
http://moinmoin.wikiwikiweb.de/MoinMoinQuestions/Errors ?


  One note about sourceforge accounts. I am not sure it is really necessary to 
change the umask in config.py to 0777. Actually 0755 (0744 ?) should be 
sufficient. Thus files created by the web user are not writeable by you, but 
if you need to do that (removing all files), all you have to do is go in some 
moinmoin python code and temporarily add a line with "os.system("chmod -R 
0777 /tmp/persistent/MY_PROJECT/") ?
   This won't prevent a stupid web-activated script to erase all data 
belonging to nfsnobody, but at least it will not be world-writable anymore, 
so a script running on the shell servers will not be able to scrap the data 
anymore.

	Vincent
