12 years agosubdirs: unify rules for "cleaning" and "normal" recursive targets
Stefano Lattarini [Sun, 10 Jun 2012 21:08:07 +0000 (23:08 +0200)]
subdirs: unify rules for "cleaning" and "normal" recursive targets

Before this change, the recursive invocation of cleaning targets in
the $(SUBDIRS) where done in inverse order, i.e., starting from the
last $(SUBDIRS) entry and proceeding towards the first.  According
to the code comments, this was done ...

    ... in an attempt to alleviate a problem that can happen when
    dependencies are enabled.  In this case, the .P file in one
    directory can depend on some automatically generated header
    in an earlier directory.  Since the dependencies are required
    before any target is examined, make bombs.

But this comment does not apply anymore to the current implementation
of automatic dependency tracking: the '.Po' and '.Plo' files does not
depend on any C header or source file, ever!

So it seems that the distinction between "normal" and "cleaning"
recursive targets is a stale leftover of an older implementation of
the automatic dependency tracking.  In fact, the Automake History
manual seems to confirm this suspect; the section "First Take on
Dependency Tracking" reads:

    Because each .P file was a dependency of Makefile, this meant
    that dependency tracking was done eagerly by make.  For instance,
    "make clean" would cause all the dependency files to be updated,
    and then immediately removed.  This eagerness also caused problems
    with some configurations; if a certain source file could not be
    compiled on a given architecture for some reason, dependency
    tracking would fail, aborting the entire build.

and the following section "Dependencies As Side Effects" reads:

    In this approach, the .P files were included using the -include
    command, which let us create these files lazily.  This avoided
    the "make clean" problem.

So the distinction between "normal" and "cleaning" recursive targets
has likely been obsolete since by then already.  We can thus remove
such distinction, thus reducing some complications and duplication in
our rules.  Doing so, the whole testsuite still passes (both with GCC
and Sun C 5.9), even the test 'c-demo.sh', which, among the other
things, exercise the setup described in the obsolete code comment
referenced above.

Finally, note that we still keep '$(RECURSIVE_CLEAN_TARGETS)' and
'$(RECURSIVE_TARGETS)' as two distinct variables, to ensure a better
backward-compatibility for any user-defined rules that happen to use
those variables.

* NEWS: Update.
* lib/am/subdirs.am ($(RECURSIVE_CLEAN_TARGETS), $(CLEAN_TARGETS)):

* t/subdir-distclean.sh: New test, check that "./configure && make

perf: beginning of a performance testsuite

Some tests in the Automake testsuite already aims only at verifying
the performance, rather than the correctness, of some operations.
Still, they are somewhat shoehorned and forced into the PASS/FAIL

(see automake bug#11512 for an example).

'AM_TESTSUITE_PERF' to "yes").  Ideally, we should provide those tests

ylwrap: preserve subdirectories in "#line" munging

If Automake is used in non-recursive mode and one of the inputs is a
yacc file, for example, "src/grammar.y", ylwrap will remove too many
directories from the output file when it adjusts the paths in it.
This results in #line directives referring to "grammar.y" instead of
"src/grammar.y".

This is a result of $input_rx simply taking all the directory
components of the absolute input path and removing them.

One solution is to store the path passed to ylwrap and replace
$input_rx with it.  This is what we do.

12 years agotests: use append mode to capture parallel make output
Stefano Lattarini [Sat, 5 May 2012 17:22:40 +0000 (19:22 +0200)]
tests: use append mode to capture parallel make output

This should fix the spurious failure reported in automake bug#11413.

This is due to the fact that the redirected output of parallel make
can racily loose lines.  For example, if GNU make (3.82) is run on
a Makefile like this:

  all = 0 1 2 3 4 5 6 7 8 9
  default: $(all)
  $(all):
        @sleep 0.$$(($RANDOM % 10)); echo $@

and has its standard output redirected in overwrite-mode to a regular
file, it looses a line of that output every 15 runs or so on a Fedora
17 system with 64 ppc64 cores and Linux 3.3.1.  Redirection in append
mode does not suffer of this problem.

See also similar commit 'Release-1-10-280-g6426999' of 2009-03-10,
"Use append mode to capture parallel test output", which tackled a
similar problem for 't/parallel-tests3.sh' and 't/lisp8.sh'.

* t/tap-more.sh: Use append mode for output from "make -j", to avoid
dropped lines.
* t/parallel-tests3.sh, t/lisp8.sh: Enhance comments.

12 years agocolor-tests: coloring can be forced on non-ANSI terminals as well
Stefano Lattarini [Mon, 30 Apr 2012 18:44:50 +0000 (20:44 +0200)]
color-tests: coloring can be forced on non-ANSI terminals as well

Before this change, colorization of testsuite output was suppressed
whenever the terminal was recognized to be a "dumb" one, incapable
of handling ANSI coloring (i.e., when the environment variable TERM
had a value of "dumb").  This happened even when the AM_COLOR_TESTS
variable was set to a value of "always".

Such a behaviour was suboptimal and slightly confusing; in fact, if
a user wants to force coloring of testsuite output that is being
redirected to a regular file, he should be able to do so even if his
terminal is not capable of handling ANSI colors -- in fact, such
terminal wouldn't be involved with the testsuite output in any way,
so why should it be allowed to influence it?

Thus, we now enable coloring of test output whenever AM_COLOR_TESTS
is set to "always", irrespective of the value of the TERM environment
variable.

* NEWS: Update.
* lib/am/check.am [%?COLOR%] (am__tty_colors): Activate colorization
of testsuite output whenever AM_COLOR_TESTS has the value of "always".
* t/ax/tap-summary-aux.sh: Export the TERM environment variable to
"dumb" when forcing colorization of the testsuite output; this should
*not* prevent such colorization from taking place, and we want to
check that this expectation really holds.
* t/ax/testsuite-summary-checks.sh: Likewise.
* t/color.sh: Likewise, and adjust some grepping checks.
* t/tap-color.sh: Likewise.  Also, remove redundant "make check"

* t/color2.sh: Likewise, and check that exporting TERM=dumb actually

this with our new optimization, and still have the test completed
in a reasonable time.
