--- Begin Message ---Package: debhelper Version: 12.2.3 Severity: normal -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi, After setting "debhelper-compat (= 12)" on golang-golang-x-tools, I encountered the following error which aborted the package build: dwz: Too few files for multifile optimization objcopy: 'debian/golang-golang-x-tools/usr/lib/debug/.dwz/x86_64-linux-gnu/golang-golang-x-tools.debug': No such file dh_dwz: objcopy --compress-debug-sections debian/golang-golang-x-tools/usr/lib/debug/.dwz/x86_64-linux-gnu/golang-golang-x-tools.debug returned exit code 1 Perplexed by this error, I removed the '-q' option from the dwz in my local /usr/bin/dh_dwz, and saw warning messages like this: dwz: debian/golang-golang-x-tools/usr/bin/authtest: .debug_info section not present dwz: debian/golang-golang-x-tools/usr/bin/benchcmp: .debug_info section not present dwz: debian/golang-golang-x-tools/usr/bin/callgraph: .debug_info section not present ... dwz: debian/golang-golang-x-tools/usr/bin/vet: .debug_info section not present It turns out that these Go compiled ELF executables have .zdebug_info rather than .debug_info section, i.e., "DWARF sections are now compressed by default" as stated in the Go 1.11 Release Notes at https://golang.org/doc/go1.11#debugging . And then, since dwz (0.12.20190711-1), "If .debug_info section not present, exit with 0. See also #931792 https://bugs.debian.org/931792, https://sourceware.org/bugzilla/show_bug.cgi?id=24766 and https://sourceware.org/git/?p=dwz.git;a=commit;h=51a7fba9895c0256888fe8996f37c598ca56749a So, I recommend that dh_dwz should have a check added to ensure the multifile actually exists before running objcopy, and if not, dh_dwz probably should print some warnings, then exit gracefully with 0. Anyhow, for golang-golang-x-tools, initially not wanting to disable dh_dwz altogether, I tried the following workaround: override_dh_dwz: dh_dwz || : But then I encountered a second problem: An empty golang-golang-x-tools-dbgsym package containing only /usr/lib/debug/.dwz/x86_64-linux-gnu/ got generated. I realized this was previously fixed in debhelper (11.4.1): * dh_strip: Remove empty /usr/lib/debug directories left over by dh_dwz. Thanks to Ferenc Wágner for reporting the issue. (Closes: #909303) But perhaps these warning messages give a clue: dh_strip: Could not find the BuildID in debian/golang-golang-x-tools/usr/bin/findcall dh_strip: Could not find the BuildID in debian/golang-golang-x-tools/usr/bin/vet ... Looking at https://salsa.debian.org/debian/debhelper/commit/423cfce04719f41d7224d75155c4e7f9a97a10e9, it appears to me that the fix for #909303: doit('rmdir', '-p', '--ignore-fail-on-non-empty', "$tmp/usr/lib/debug"); currently gets to run only if BuildID was found. Sorry, I probably should have filed a second bug report for dh_strip, but these two issues seem related, and I am lazy. :-) Many thanks!

[ Translations ] * Update Portuguese translation (Américo Monteiro) (Closes: #927394) . [ Niels Thykier ] * dh_installsystemduser: Fix bug that would neuter sorting of unit files and make the resulting maintscripts unreproducible. Thanks to Daniel Kahn Gillmor for reporting the bug. (Closes: #932646) * dh_dwz: Remove the -q flag when calling dwz(1). It is sufficiently silently with -q and aids with debugging for others. (Closes: #933561, #931792) * dh_dwz: Gracefully handle when dwz fails to create a multifile but succeeds anyway by default. The previous behaviour of insisting on a multifile can be obtained by explicitly passing --dwz-multifile. (Closes: #933541) * dh_dwz: Skip multifile generation for udeb packages. (Closes: #933212) * dh_makeshlibs: Attempt to automatically detect udeb packages for a given (non-udeb) library package. In simple cases, it can replace the need for an explicit --add-udeb parameter. However, there are many cases where the auto-detection falls short and --add-udeb is still needed (see dh_makeshlibs(1) for details). Packagers are advised to verify the resulting shlibs file before removing --add-udeb in an upload.
