Bug#627063: python-debian: GpgInfo.from_sequence has an arbitrary check on keyrings

[Julien Cristau]

Package: python-debian
Version: 0.1.18
Severity: normal

debian.deb822.GpgInfo.from_sequence takes a list of keyrings, and then
checks if the given files exist.  However gpg and gpgv's --keyring
argument can take a filename relative to the GnuPG home directory, i.e.
gpgv --keyring pubring.gpg < file
works and looks at ~/.gnupg/pubring.gpg whatever the current directory.

It would be nice if you could change this:

--- a/lib/debian/deb822.py
+++ b/lib/debian/deb822.py
@@ -663,7 +663,7 @@ class GpgInfo(dict):
         #args.extend(["--status-fd", "1", "--no-default-keyring"])
         args.extend(["--status-fd", "1"])
         import os
-        [args.extend(["--keyring", k]) for k in keyrings if os.path.isfile(k) and os.access(k, os.R_OK)]
+        [args.extend(["--keyring", k]) for k in keyrings]
         
         if "--keyring" not in args:
             raise IOError, "cannot access any of the given keyrings"

and that way rely on gnupg itself to find the keyring files.

Cheers,
Julien
