Thank your for the feedback. It also seems to me that even with the zip upload
case supported, allowing to upload a zip file with the same name as an existing
module is going to be confusing.. whichever precedence we choose may not be the
one the user expects (e.g importing by mistake a zip with the same name as an
existing module)

Thanks, that's very much appreciated!

Excellent, thanks for merging my changes in your branch!
I have a few remaining things to check and then we can do the final merge of
your work: there are a few pathological cases during module installation where
we explicitly call tools.file_open on an ambiguous path, still causing a great
number of useless zip-related i/o syscalls before eventually finding the
regular file somewhere else.

Title:
  file_open is not safe and performs too many useless syscalls

Status in OpenERP Server:
  In Progress

Bug description:
  It happens with 5.0 and certainly with 6.1 too.

  When you update the list of modules, the application calls:
    tools.file_open(terp_file)

  And file_open will browse all the parents of the "addons_path" for a zip file ... 
  I've added a statement to trace the call to "open()" :

  open('/home/florent/erpdemo/parts/openerp-server/bin/addons/account.zip', 'rb')
  open('/home/florent/erpdemo/parts/openerp-server/bin/addons.zip', 'rb')
  open('/home/florent/erpdemo/parts/openerp-server/bin.zip', 'rb')
  open('/home/florent/erpdemo/parts/openerp-server.zip', 'rb')
  open('/home/florent/erpdemo/parts.zip', 'rb')
  open('/home/florent/erpdemo.zip', 'rb')
  open('/home/florent.zip', 'rb')
  open('/home.zip', 'rb')
  open('/.zip', 'rb')

  This behaviour is seen on module installation or upgrade too.
  It is probably a security issue which impacts performance as well.
