unable to copy small files with nautilus on cifs mount

[Alain DELANGE]

I have this bug on two different computers with ubuntu 18.04
I never encounter this this 16.04 and any previous releases

I am working on a web site with many (twenty) small php files (less than 100bytes)

When I copy paste the full www folder nautilus hangs on a certain file, a small one...
When I copy paste one small file from a subfolder of www to an other sufolder it hangs

I got the message :
Copie de index.php vers pictures
0 octet / 65 octets - environ 596 523 heures restantes

Sometimes I got a 0 byte in my folder which is hard to remove even on terminal

But If I do a paste again, just after the stall, I got from nautilus the message the file exists and if I "replace" it works.

Copying/pasting a file in the same folder don't work at all :
Duplication de index.php
0 octet / 65 octets - environ 596 523 heures restantes

*************
context :
I am working with different computers physicals and virtualbox on these files with absolutely no problems
The configuration is always the same:
My cifs mount are mounted with autofs on /home/ad/auto
I have something like that in autofd configuration files:

moi -fstype=cifs,credentials=/home/ad/.credentials/ad-credentials,iocharset=utf8 ://192.168.1.20/ad_moi

I have the problem when I am on the same computer, the one with samba server, in this case I have
127.0.0.1 instead of 192.168.1.20in config files.

The problem is not with autofs. I can get it without it...

I can reproduce it on an other computer with ubuntu 19.10
the copy/paste of www hangs on the first file : a 388 bytes png file

copying with terminal with cp works fine

Thank you for your bug report, it could be useful to report to the software writters directly on https://gitlab.gnome.org/GNOME/nautilus/issues/
(note that it could be a gvfs/glib(gio) issue, do you get the same problem with gio copy?)

After further test
the files, the samba server is ubuntu 18.04 lts

apt-cache policy samba
samba:
  Installé : 2:4.7.6+dfsg~ubuntu-0ubuntu2.9
  Candidat : 2:4.7.6+dfsg~ubuntu-0ubuntu2.9

I start a virtual box with ubuntu 16.04lts, access to my files through autofs and do a copy paste on my www folder : OK

apt-cache policy nautilus
nautilus:
  Installé : 1:3.18.4.is.3.14.3-0ubuntu6

I start an other virtualbox machine with ubuntu 18.10 an do the same copy paste of my folder :
duplication de 1/160 fichiers and hangs !
nautilus:
  Installé : 1:3.26.4-0~ubuntu18.04.2

gio copy hangs after the firt file

gio copy -p auto/moi/PHP/Newsletter/mob/* auto/moi/PHP/Newsletter/mob5/
684 octets sur 684 octets transférés (684 octets/s)

[Alain DELANGE (alain-delange)]

so you think we have to search the problem with gvfs ?

[Sebastien Bacher (seb128)]

IF the gio copy command has the same issue then yes it's probably gvfs rather than nautilus to blame, you should report your finding on https://gitlab.gnome.org/GNOME/gvfs since that's the right place for upstream code issues (the Ubuntu team does integration and contribute in those projects but on launchpad you then only hit a subset of the people who can help getting it resolved)

ok thanks
