Package: libusb
Version: 0.1.12
Severity: minor
User: [email protected]
Usertags: environment
Dear Maintainer,
While working on the “reproducible builds” effort [1], we have noticed
that libusb could not be built reproducibly; the diff between two builds
is:
# https://tests.reproducible-builds.org/rb-pkg/unstable/amd64/libusb.html
├── ./usr/lib/x86_64-linux-gnu/libusb.so
│ @@ -1,3 +1 @@
│ -/* GNU ld script. */
│ -GROUP ( /lib/x86_64-linux-gnu/libusb-0.1.so.4.4.4 )
│ -
│ +/* GNU ld script. */\nGROUP ( /lib/x86_64-linux-gnu/libusb-0.1.so.4.4.4
)\n
This difference is down to debian/rules calling echo(1) with an argument
that contains a literal backslash. The behaviour of echo(1) in that
case is (according to POSIX) implementation-defined. Since debian/rules
uses echo(1) from the building user's shell, the build output differs
when the building user uses SHELL=bash v. SHELL=dash:
% LC_ALL=C dash -c 'echo "foo\nbar"'
foo
bar
% LC_ALL=C bash -c 'echo "foo\nbar"'
foo\nbar
%
The following patch removes the use of implementation-defined behaviour:

]]]
This patch should also make the build reproducible, but I didn't test that.
Note that when built under bash, the .so file contains a literal «\n»
sequence (two bytes). I'm assuming that might have user-visible
consequences but I don't know what exactly they would be.
Cheers,
Daniel
