Bug#868064: dh-strip-nondeterminism: Emits noisy warning when tmpdir() is not created

[Niels Thykier]

Package: dh-strip-nondeterminism
Version: 0.035-2
Severity: minor
Tags: patch upstream

Hi,

When dh_strip_nondeterminism is called, it will emit a noisy warning
about the tmpdir not existing when this is the case while still
exiting with 0 after said warning.  Example:

"""
$ dh_strip_nondeterminism
Can't stat debian/goodbye-dh: No such file or directory
 at /usr/bin/dh_strip_nondeterminism line 71.
$ echo $?
0
"""

Attached patch avoids said warning.  This may become more relevant due
to the following debhelper compat 11 change:

"""

  * dh_auto_install will now only create the destination directory it
    needs. Previously, it would create the package build directory for
    all packages.  This will not affect packages that only build with
    debhelper commands, but it may expose bugs in commands not
    included in debhelper.
"""

Thanks,
~Niels
