Bug#1082719: debhelper: dh-sequence-single-binary not working with compat 14

Package: debhelper
Version: 13.20
Severity: normal

Hi! I've just tried out compat 14 to start preparing one of my packages to it, but noticed that the dh-sequence-single-binary dependency doesn't work as expected. According to the manpage, if that addon is used, dh_auto_build should install files to debian/singlepackage/, not debian/tmp/, but this is not what I'm observing. Here's a reproducer:


   $ cat Makefile
   .POSIX:

# Paths

   PREFIX = /usr/local
   BINDIR = bin

# Utilities

   INSTALL = install
   MKDIR = mkdir -p
   RM = rm -f

all: main main: main.o main.o: main.c install: main

        $(MKDIR) $(DESTDIR)$(PREFIX)/$(BINDIR)
        $(INSTALL) main $(DESTDIR)$(PREFIX)/$(BINDIR)

uninstall:

        $(RM) $(DESTDIR)$(PREFIX)/$(BINDIR)/main

clean:

        $(RM) main main.o

.PHONY: all clean install uninstall $ cat main.c

   #include <stdio.h>

int main(void) {

        puts("Hello, world!");
        return 0;
   }

$ cat debian/changelog

If I build the package as-is, the build fails as follows:

   dh_auto_install -- PREFIX=/usr
        make -j12 install DESTDIR=/tmp/tmp.hKSeWe1Ril/compat-14-test/debian/tmp

   install --strip-program=true main

   dh_missing: warning: usr/bin/main exists in debian/tmp but is not installed 
to anywhere
        The following debhelper tools have reported what they installed (with 
files per package)
        * dh_installdocs: compat-14-test (0)
        If the missing files are installed by another tool, please file a bug 
against it.
        When filing the report, if the tool is not part of debhelper itself, 
please reference the
        "Logging helpers and dh_missing" section from the "PROGRAMMING" guide 
for debhelper (10.6.3+).
         (in the debhelper package: /usr/share/doc/debhelper/PROGRAMMING.md.gz)
        Be sure to test with dpkg-buildpackage -A/-B as the results may vary 
when only a subset is built
        If the omission is intentional or no other helper can take care of this 
consider adding the
        paths to debian/not-installed.
   dh_missing: error: missing files, aborting
   make: *** [debian/rules:4: binary] Error 255

As you can see, the files get installed in debian/tmp even if the addon is present, which then leads to a failure. The same exact package, under compat 13, builds fine.

Am I misunderstanding what dh-sequence-single-binary should do? If I add a bare debian/install file then the build completes successfully under compat 14, but fails in compat 13.


Bye!
