gEDA-bug: [Bug 698565] Re: Save button doesn't respect permissions

[Eivind Kvedalen <698565@xxxxxxxxxxxxxxxxxx>]

I don't think there is, unless we replace the g_file_set_contents call
and write directly to the file, but I think that would introduce the
possibility of writing partial files instead (crash, out of disk space,
etc). So choosing between the two, the possible race condition is
probably the best? (I was aware of it btw, the security hole is
mentioned on the access(2) man page).

Title:
  Save button doesn't respect permissions

Status in GPL Electronic Design Automation tools:
  Triaged

Bug description:
  File->Save _sometimes_ fails to respect file-permissions.

  For example, when modifying a file with permissions:
  -r--r--r-- 1 pcjc2 pcjc2 510 2008-12-27 10:23 /home/pcjc2/geda/share/gEDA/sym/analog/resistor-2.sym

  The log window often gets the following text:
  o_save: Could not open [/home/pcjc2/geda/share/gEDA/sym/analog/resistor-2.sym]
  Could NOT save page [/home/pcjc2/geda/share/gEDA/sym/analog/resistor-2.sym]
  (Arguably we just need one descriptive message with a reason).

  However; on some occasions, the file gets overritten, creating a new file with permissions:
  -rw-r--r-- 1 pcjc2 pcjc2 490 2008-12-27 10:29 /home/pcjc2/geda/share/gEDA/sym/analog/resistor-2.sym

  Obviously this is not good!
