What is the text of the formula that gives "#NOM ?", i.e. click on it and copy and paste the text that appears in the formula editor e.g. is it something like ='file:///home/caolan/Documents/test.ods'#$Sheet1.A9 or something like ='smb:///home/caolan/Documents/test.ods'#$Sheet1.A9 Here is the text : ='file:///mnt/serveur/aaa/essai2.ods'#feuille1.b5 I will also attach my 2 files essai1 & essai2 Created attachment 130451 [details]
essai1 file
Created attachment 130452 [details]
essai2 file
I have done other tests and it might be linked to capital letters. My folder "/mnt/serveur/aaa" is in fact "/mnt/serveur/AAA" and it might be the reason why he cannot create the link. If i save a new set of essai1 & 2 files into a new folder called "/mnt/serveur/bbb" (no capital letter) the problem disappear. This issue is very annoying. Can I do anything to help you to solve it ? I wasn't able to reproduce this, but what are the details of the samba server, is it windows or samba itself. and when you type "mount" on the client, what is the line for /mnt/serveur, perhaps some casemapping option is being used, or not being used. The samba server works on a FC5 server. His config file is : ************* /etc/smb.conf # Samba config file created using SWAT [global] workgroup = MYGROUP netbios name = SAMBA server string = Samba Server log file = /var/log/samba/%m.log max log size = 1000 ldap ssl = no hosts allow = 127.0.0.1, 192.168.0. hosts deny = all [homes] comment = Home Directories read only = No **************** On the laptop (running also FC5) I mount the server thru /etc/fstab with the following line : //192.168.0.4/bg /mnt/serveur cifs rw,uid=bgirin,username=xx,password=xx 0 0 where 192.168.0.4 is the ip address of the server. I can reproduce now, will get onto it Great ! Please try this for me... as root edit the script /usr/lib/openoffice.org2.0/program/soffice and change # file locking now enabled by default SAL_ENABLE_FILE_LOCKING=1 export SAL_ENABLE_FILE_LOCKING to be instead # file locking now enabled by default #SAL_ENABLE_FILE_LOCKING=1 #export SAL_ENABLE_FILE_LOCKING i.e. comment those two lines out and tell me if that "fixes" it Created attachment 132003 [details]
simple lock test
e.g.
./a.out /mnt/serveur/AAA/essai1.ods lock
./a.out /mnt/serveur/AAA/essai1.ods unlock
The "case mapping" led me astray, calc makes the text of a failed operation into lowercase, the problem is simply that once the document has been opened with a read-write lock over cifs, then it cannot be opened simultaneously and read from. e.g. > oocalc /mnt/serveur/AAA/essai1.ods & ... > cp /mnt/serveur/AAA/essai1.ods /tmp Permission denied Once the cock-up has occured, OOo lowercases the failed text so that's what's there on save. Presumably if you then close the referred doc, and move it to a location which is equal to the new wrong string it'll find it again, but that's neither here nor there. caolanm->fenlason: Is this strict locking a feature or bug ? Coalan, I have followed your instruction i.e. commenting the 2 lines in /usr/lib/openoffice.org2.0/program/soffice and that has fixed the bug for me. I have tried several tests, with different files and all are working now. Thank you very much for solving this issue ! This is working as expected, if OpenOffice.org fails to deal properly with locking I'd say it is an OpenOffice.org bug. Please Reopen if you have more info that lead to think it is a samba bug instead. |
