Package: dpkg-dev
Followup-For: Bug #872381
Hello.
Please consider this new patch queue instead of the old or untested
ones. With this one applied on 279c6ccb, the package builds and
passes all tests.
* scripts/mk: only use ASCII characters
Cosmetic independent suggestion.
* scripts/mk: protect files against double inclusion
The variables are renamed as you have recommended.
The test is fixed (ifdef fails on a defined but empty variable).
* scripts/mk: stop hard-coding dpkg_datadir
Already discussed.
* scripts/mk/buildopts.mk: search once for parallel= in DEB_BUILD_OPTIONS
> > [...DEB_BUILD_OPTION_PARALLEL empty instead of undefined
> > when parallel= is missing...]
> [kind of an API change].
I have changed my patch and updated the comment.
However..
The policy only describes 'parallel=N' when N is a positive integer.
I think we should assume that the option is either missing or valid.
For me, 'parallel=' is as incorrect as 'parallel=foo'.
> I think it might perhaps make more sense to fallback to setting it
> to 1 if it's missing, but I need to ponder about possible
> consequences/fallout, etc.
I doubt any sensible default exist.
* 1 is safe/produces readable logs and $max_available_processors is fast.
* the policy/debhelper/... have found no one-size-fits-all solution.
* scripts/buildflags.mk: add missing GCJFLAGS
Fixes a bug.
* scripts/buildflags.mk: generate the _FOR_BUILD variant of each variable
* scripts/buildflags.mk: sort the flag list
These changes hopefully prevent new missing flags in the future (the
output of dpkg-buildflags is sorted).
* scripts/*.mk: reduce the number of subprocesses
* scripts/t: use loops instead of repetitions, check exports and overrides
* all four combinations of existing/new scripts/mk/*.mk pass the
existing/new tests in scripts/t/mk/*.mk.
* comparing the time taken by tests gives a rough idea of the speed
gain
architecture.mk 30 times faster (probably no gain under dpkg-buildpackage)
buildflags.mk 20 times faster
pkg-info.mk 4 times faster
buildtools.mk 20% faster

In which context do you expect GNU Make but a non recent sed?
Should I rewrite the regular expressions without -r/-E?

A generic format would be more maintainable in the long term.
Something like that would be convenient for the makefiles.
dpkg-architecture --print-format='${Dollar}(eval export ${key} ?= ${value})'
dpkg-buildflags --print-format='${Dollar}(eval ${key}:=${value})'
dpkg-parsechangelog --print-format='${Dollar}(eval DEB_SOURCE:=${Source})
${Dollar}(eval export SOURCE_DATE_EPOCH?=${Timestamp}) ..'
dpkg-vendor --print-format'${Dollar}(eval DEB_VENDOR:=${Vendor}) ${Dollar}(eval
DEB_PARENT_VENDOR:=${Parent})'
* scripts/buildtools.mk: style suggestions
This arguably improves the readability, and fixes a minor issue
($(findstring nostrip,...) unwantedly matches arduinostrip).
* scripts/t/mk/buildflags.mk: fix test of _MAINT_APPEND when TEST_ is empty
This fixes a minor issue. During a test with
DEB_BUILD_OPTIONS=noopt, TEST_CXXFLAGS was empty and caused the test
of DEB_CXXFLAGS_MAINT_APPEND to fail because the correct result is
not a concatenation, Make strips a space. This issue can also be
seen with 1.22.5.

Subject: [PATCH 01/11] scripts/mk: only use ASCII characters
The policy recommends english, so french parenthesis must be replaced.
More generally, prudence recommends ASCII in Make scripts.

Subject: [PATCH 08/11] scripts/*.mk: reduce the number of subprocesses
In architecture.mk, each unset variable was spawning a shell.
In buildapi.mk, each expansion was spawning a shell.
Default.mk and vendor.mk both expand DPKG_BUILD_API.
In buildflags.mk, each first expansion of an unset variable was
spawning a shell.
DPKG_EXPORT_BUILDFLAGS expands all variables.
In pkg-info.mk, each variable was spawning its own shell.
Vendors.mk was correct but use the same mechanism for consistency.

Subject: [PATCH 09/11] scripts/t: use loops instead of repetitions, check
exports and overrides
Replace copied lines with Make loops.
Add tests:
architecture variable override,
buildflags set and export,
GCJFLAGS,
buildtool override and export.

Subject: [PATCH 10/11] scripts/buildtools.mk: style suggestions
* $(filter nostrip,$(DEB_BUILD_OPTIONS)) is slightly better than
$(findstring) because the latter matches 'arduinostrip'.
* An explicit test of $(origin) instead of ?= makes the intent of each
stanza more readable (first ensure that TOOL is set, then
TOOL_FOR_BUILT).
* Special case nostrip outside generic dpkg_buildtool_setvar
procedure.
