Since we don't use suffix rules nor implicit rules in gdb, we can
disable them. The advantage is a slightly faster make [1].
Here are some numbers about the speedup. I ran this on my trusty old
Intel Q6600, so the time numbers are probably higher than what you'd get
on any recent hardware. I ran "make" in the gdb/ directory of an
already built repository (configured with --enable-targets=all). I
recorded the time of execution (average of 5). I then ran "make -d" and
recorded the number of printed lines, which gives a rough idea of the
number of operations done.
I compared the following configurations, to see the impact of both the
empty .SUFFIXES target and the empty pattern rules, as well as running
"make -r", which can be considered the "ideal" case.
A - baseline
B - baseline + .SUFFIXES
C - baseline + pattern rules
D - baseline + .SUFFIXES + pattern rules
E - baseline + make -r
config | time (s) | "make -d"
-----------------------------
A | 5.74 | 2396643
B | 1.19 | 298469
C | 2.81 | 1266573
D | 1.13 | 245489
E | 1.01 | 163914
We can see that the empty .SUFFIXES target has a bigger impact than the
empty pattern rules, but still it doesn't hurt to disable the implicit
pattern rules as well.
There are still some mentions of implicit rules I can't get rid of in
the "make -d" output. For example, it's trying to build .c files from
.w files:
Looking for an implicit rule for '/home/simark/src/binutils-gdb/gdb/infrun.c'.
Trying pattern rule with stem 'infrun'.
Trying implicit prerequisite '/home/simark/src/binutils-gdb/gdb/infrun.w'.
and trying to build Makefile.in from a bunch of extensions:
Looking for an implicit rule for 'Makefile.in'.
Trying pattern rule with stem 'Makefile.in'.
Trying implicit prerequisite 'Makefile.in.o'.
Trying pattern rule with stem 'Makefile.in'.
Trying implicit prerequisite 'Makefile.in.c'.
Trying pattern rule with stem 'Makefile.in'.
Trying implicit prerequisite 'Makefile.in.cc'.
... many more ...
If somebody knows how to disable them, we can do it, but at this point
the returns are minimal, so it is not that important.
I verified that both in-tree and out-of-tree builds work.
[1] Switching from explicit rules to pattern rules for files in
subdirectories actually made it slower, so this is kind of a way to
redeem myself. But it the end it's faster than it was previously,
so it was all worth it. :)

Since GNU make is now required to build GDB, we can remove everything
that checks whether the current make implemention is the GNU one or
not. I simply removed the @GMAKE_TRUE@ prefixes and removed the whole
lines that were prefixed with @GMAKE_FALSE@.
I removed the code in the configure scripts that set those variables.
I also removed the following bits from the configure scripts:
AC_CHECK_PROGS(MAKE, make): GNU make already defines a MAKE variable
internally to be used when invoking Makefiles recursively. I don't see
this variable being used anywhere else (in scripts for example), so I
think it's safe for removal.
AC_PROG_MAKE_SET: This macro defines a SET_MAKE output variable, which
is meant to be used in Makefiles to define the MAKE variable when
using an implementation of make that doesn't already define it.
Since we are now requiring GNU make, we don't need it anymore.
Plus, I don't see SET_MAKE being used anywhere, so I don't think it
was actually doing anything...

This is an initial attempt to introduce some mechanisms to identify
racy testcases present in our testsuite. As can be seen in previous
discussions, racy tests are really bothersome and cause our BuildBot
to pollute the gdb-testers mailing list with hundreds of
false-positives messages every month. Hopefully, identifying these
racy tests in advance (and automatically) will contribute to the
reduction of noise traffic to gdb-testers, maybe to the point where we
will be able to send the failure messages directly to the authors of
the commits.
I spent some time trying to decide the best way to tackle this
problem, and decided that there is no silver bullet. Racy tests are
tricky and it is difficult to catch them, so the best solution I could
find (for now?) is to run our testsuite a number of times in a row,
and then compare the results (i.e., the gdb.sum files generated during
each run). The more times you run the tests, the more racy tests you
are likely to detect (at the expense of waiting longer and longer).
You can also run the tests in parallel, which makes things faster (and
contribute to catching more racy tests, because your machine will have
less resources for each test and some of them are likely to fail when
this happens). I did some tests in my machine (8-core i7, 16GB RAM),
and running the whole GDB testsuite 5 times using -j6 took 23 minutes.
Not bad.
In order to run the racy test machinery, you need to specify the
RACY_ITER environment variable. You will assign a number to this
variable, which represents the number of times you want to run the
tests. So, for example, if you want to run the whole testsuite 3
times in parallel (using 2 cores), you will do:
make check RACY_ITER=3 -j2
It is also possible to use the TESTS variable and specify which tests
you want to run:
make check TEST='gdb.base/default.exp' RACY_ITER=3 -j2
And so on. The output files will be put at the directory
gdb/testsuite/racy_outputs/.
After make invokes the necessary rules to run the tests, it finally
runs a Python script that will analyze the resulting gdb.sum files.
This Python script will read each file, and construct a series of sets
based on the results of the tests (one set for FAIL's, one for
PASS'es, one for KFAIL's, etc.). It will then do some set operations
and come up with a list of unique, sorted testcases that are racy.
The algorithm behind this is:
for state in PASS, FAIL, XFAIL, XPASS...; do
if a test's state in every sumfile is $state; then
it is not racy
else
it is racy
(The algorithm is actually a bit more complex than that, because it
takes into account other things in order to decide whether the test
should be ignored or not).
IOW, a test must have the same state in every sumfile.
After processing everything, the script prints the racy tests it could
identify on stdout. I am redirecting this to a file named racy.sum.
Something else that I wasn't sure how to deal with was non-unique
messages in our testsuite. I decided to do the same thing I do in our
BuildBot: include a unique identifier in the end of message, like:
gdb.base/xyz.exp: non-unique message
gdb.base/xyz.exp: non-unique message <<2>>
This means that you will have to be careful about them when you use
the racy.sum file.
I ran the script several times here, and it did a good job catching
some well-known racy tests. Overall, I am satisfied with this
approach and I think it will be helpful to have it upstream'ed. I
also intend to extend our BuildBot and create new, specialized
builders that will be responsible for detecting the racy tests every X
number of days.

When running tests in parallel, each test puts its generated files in a
different directory, under "outputs". I think it would be nice if it
was always the case, as it would isolate the test cases a bit more. An
artifact created by a test wouldn't get overwritten by another test.
Also, it makes it easier to clean up. A lot of executables are left all
over the place because their names do not appear in gdb.*/Makefile. If
everything is in "outputs", then we just have to delete that directory
(which we already do).
At the same time it makes the gdb.foo directories and their Makefiles
useless in the build directory, since they are pretty much only used for
cleaning.
What do you think?

While testing the following patch,
[PATCH] Always organize test artifacts in a directory hierarchy
https://sourceware.org/ml/gdb-patches/2016-01/msg00133.html
I noticed that it broke Ada testing. This lead me to think that
parallel testing when building in-tree didn't work previously in Ada.
It is confirmed by this test:
$ make check TESTS="gdb.ada/fun_addr.exp" -j 2
...
Running ./gdb.ada/fun_addr.exp ...
FAIL: gdb.ada/fun_addr.exp: compilation foo.adb
...
This patch fixes in-tree parallel testing for Ada, and consequently
serial and parallel testing when the aforementioned patch is applied.
The problem originates from the fact that Ada support code cd's to the
builddir before compiling. In itself it's not a problem, it allows to
place intermediate auto-generated files in that directory. The Ada
compilation refers to the source file, which is in another directory,
only by its base name (e.g. foo.adb). In serial mode, that worked
because builddir was the same as the source directory (e.g.
gdb.ada/fun_addr/). In an out-of-tree build, it works because the
source directory is added as an include directory (note: this is not the
same $srcdir as autoconf's):
set srcdir [file dirname $source]
additional_flags=-I$srcdir
which becomes:
additional_flags=-I/home/emaisin/build/binutils-gdb/gdb/testsuite/gdb.ada/fun_addr
However, when building in-tree, srcdir is relative: ./gdb.ada/fun_addr.
When using parallel or always-in-outputs-directory mode, we are cd'ed in
the outputs directory. So -I$srcdir is relative to the current
directory, which is wrong.
To fix it, I made the TCL variable srcdir (set in site.exp, from which
everything else is derived) always absolute. It is done by assigning
autoconf's abs_srcdir instead of autoconf's srcdir. This way -I$srcdir
will always be good, regardless of where we cd'ed to. A small apparent
change is that when running tests, DejaGnu will say:
Running /tmp/binutils-gdb/gdb/testsuite/gdb.ada/fun_addr.exp ...
instead of
Running ./gdb.ada/fun_addr.exp ...
I hope it's not too much of an annoyance. I think that it should make
the testsuite a tiny bit more robust against other bugs of the same
class.
Regtested in & out of tree, only with native target.
gdb/testsuite/ChangeLog:
* Makefile.in (abs_srcdir): Assign @abs_srcdir@.
(site.exp): Assign abs_srcdir to tcl's srcdir.
|
|
gdb/testsuite/ChangeLog:
* Makefile.in (DO_RUNTEST): Add --status and update usages.
|
|
By default, if a test driver (a test .exp) ends with an uncaught
error/exception, the runtest command will still have a return code of 0
(success). However, if a test (or the environment) is broken and does
not work properly, it should be considered as failed so that we can
notice it and fix it.
Passing the --status flag to runtest will make it return an error if one
of the test it runs ends up with an uncaught error.
gdb/testsuite/ChangeLog:
* Makefile.in (check-single): Pass --status to runtest.
(check/%.exp): Likewise.
|

When using the check-parallel target, the return code of make is always 0,
regardless of test results. This patch makes it return the same code as
the "make do-check-parallel" sub-command. So if there is a FAIL somewhere,
non-zero will be returned by make.
For the sake of example, I introduced a failure in gdb.base/break.exp.
$ make check-single TESTS="gdb.base/break.exp gdb.python/py-value.exp" && echo 'Success :D' || echo 'Fail :('
...
FAIL: gdb.base/break.exp: allo
...
Fail :(
I think the parallel run should do the same. Currently:
$ make check-parallel TESTS="gdb.base/break.exp gdb.python/py-value.exp" && echo 'Success :D' || echo 'Fail :('
...
FAIL: gdb.base/break.exp: allo
...
Success :D
And with the patch (no big surprises there):
$ make check-parallel TESTS="gdb.base/break.exp gdb.python/py-value.exp" && echo 'Success :D' || echo 'Fail :('
...
FAIL: gdb.base/break.exp: allo
...
Fail :(

A sanity-check in my release scripts caught something: After having
created the tarballs, I verify that no checked-in file disappeared
in the process, and lo and behod, it found that the following file
got wiped:
- gdb/testsuite/dg-extract-results.py:
And it's not part of the tarball either.
I don't understand while we delete all *.py files in gdb/testsuite,
since I don't see a rule that expected to create one. A run of the
testsuite also doesn't seem to be creating .py files there.
I traced this to the following commit, which unfortunately provided
no explanation. Perhaps we used to run some tests in the gdb/testsuite
directory and caused files to be left behind there. Perhaps we still
do today?
In the meantime, Executive Decision: In order to allow me to create
tarballs without losing files, I removed it. It's easy to put something
back if we find out why it might still be needed.

We add a new dir gdb.perf in testsuite for all performance tests.
However, current 'make check' logic will either run dejagnu in
directory testsuite or iterate all gdb.* directories which has *.exp
files. Both of them will run tests in gdb.perf. We want to achieve:
1) typical 'make check' should not run performance tests. In each perf
test case, GDB_PERFTEST_MODE is checked. If it doesn't exist, return.
2) run perf tests easily. We add a new makefile target 'check-perf'.

This switches "make check" to fully parallel mode.
One primary issue facing full parallelization is the overhead of
"runtest". On my machine, if I "touch gdb.base/empty.exp", making a
new file, and then "time runtest.exp", it takes 0.08 seconds.
Multiply this by the 1008 (in my configuration) tests and you get ~80
seconds. This is the overhead that would theoretically be present if
all tests were run in parallel.
However, the problem isn't nearly as bad as this, for two reasons.
First, you must divide by the number of jobs, assuming perfect
parallelization -- reasonably true for small -j numbers, based on the
results I see.
Second, the current test suite parallelization approach bundles the
tests, largely by directory, but also splitting up gdb.base into two
halves.
I was curious to see how the current bundling played out in practice,
so I ran "make -j1 check RUNTEST='/bin/time runtest'". This invokes
the parallel mode (thus the bundling) and then shows the time taken by
each invocation of runtest.
Then, I ran "/bin/time make -j3 check". (See below about -j2.)
The time for the entire -j3 test run was the same as the time for
"gdb.base1". What this means is that gdb.base1 is currently the
time-limiting run, preventing further parallelization gains.
So, I reason, whatever overhead we see from full parallelization will
only be seen by "-j1" and "-j2".
I then tried a -j2 test run. This does take longer than a -j3 build,
meaning that the gdb.base1 job finishes and then proceeds to other
runtest invocations.
Finally I tried a -j2 test run with the appended patch.
This was 9% slower than the -j2 run without the patch.
I think that is a reasonable slowdown for what is probably a rare
case. I believe this patch will yield faster test results for all -j
values greater than 2. For -j3 on my machine, the test suite is a few
seconds faster; I didn't try any larger -j values.
For -j1, I went ahead and changed the Makefile so that, if no -j
option is given, then the "check-single" mode is used. You can still
use "make -j1 check" to get single-job parallel-mode, though of course
there's no good reason to do so.
This change is likely to speed up the plain "make check" scenario a
little as we will now bypass dg-extract-results.sh.
One drawback of this change is that "make -jN check" is now much more
verbose. I generally only look at the .sum and .log files, but
perhaps this will bother some.
Another interesting question is scalability of the result. The
slowest test, which limits the scalability, took 80.78 seconds. The
mean of the remaining tests is 1.08 seconds. (Note that this is just
a rough estimate, since there are still outliers.)
This means we can run 80.78 / 1.08 =~ 74 tests in the time available.
And, in this data set (slightly older than the above, but materially
the same) there were 948 tests. So, I think the current test suite
should scale ok up to about -j12.
We could improve this number if need be by breaking up the biggest
tests.
