[Buildroot] [PATCH 0/4] rt-tests: patches rename & versoin bump & support of non-NPTL tools

[Alexey Brodkin]

This series introduces significant changes to "rt-tests" package.

 1. Now patches are named in accordance to new naming scheme (without leading
    package name)

 2. Origin of sources is switched to Debian snapshots FTP to real origin in
    kernel's git repo. So no need to track Debian folders etc, just bump version
    number when required.

 3. As mentioned above version with a simple move version is bumped to the most
    recent one.

 4. Probably the most interesting feature - now even if there's no NTPL-enabled
    toolchain for a given platform user still may build some nice and helpful
    tests. For example "hackbench" etc.

Alexey Brodkin (4):
  rt-tests: rename patch to the new convention
  rt-tests: switch site from Debian snapshot to Linux's git
  rt-tests: bump version to 0.89
  rt-tests: allow building subset of tests with non-NPTL toolchains

[Buildroot] [PATCH 1/4] rt-tests: rename patch to the new convention

[Alexey Brodkin]

As a preparation to the introduction of an additional patch to rt-tests,
let's rename the existing patch to the new naming convention.

[Buildroot] [PATCH 2/4] rt-tests: switch site from Debian snapshot to Linux's git

[Alexey Brodkin]

Origin of "rt-tests" is:
git://git.kernel.org/pub/scm/linux/kernel/git/clrkwllms/rt-tests.git

Switching to this new "origin" simplifies version bumping because there's
no need in updating Debian snapshot folder as it was done already here:

[Buildroot] [PATCH 3/4] rt-tests: bump version to 0.89

[Alexey Brodkin]

With this change we're moving to the latest version of rt-tests.

Existing patches were updated so they apply on sources without errors and
warnings.

In "01-fix-build-system.patch" CFLAGS substitution was removed because
now external CFLAGS are accepted:

[Buildroot] [PATCH 4/4] rt-tests: allow building subset of tests with non-NPTL toolchains

[Alexey Brodkin]

Some architectures are still stuck with non-NPTL toolchains.
These are for example ARC, Blackfin, Xtensa etc.

Still rt-tests are very good benchmarks and it would be good to enable use of
at least selected (those that will be built) tests on those architectures.

This change makes it possible to only build subset of tests that don't require
NPTL calls.

Following tests will be built with non-NPTL toolchain:
 * signaltest
 * ptsematest
 * sigwaittest
 * svsematest
 * sendme
 * hackbench

03-fix-non-nptl-buil.patch was submitted upstream:
https://www.mail-archive.com/linux-kernel at vger.kernel.org/msg762958.html
so as soon as it is accepted with the next version bump this patch should be
removed.

+Some architectures are still stuck with non-NPTL toolchains.

+
+By default behavior is not modified - all tests are built, but if one wants

+or modify "HAVE_NPTL" variable right in Makefile and execute "make".

Indeed, threads are required.
So I should have put dependency on BR2_TOOLCHAIN_HAS_THREADS.

Thanks for pointing to this mistake.

If other patches for rt-tests are OK then I'll re-submit only the last
one.

Applied patches 1 to 3. Patch 4 not applied as a new version was sent.
However, I wanted to mention two things:

 * You should never resend a new version of just one patch. Always send
   the complete series again, even if only one patch has changed. I was
   mistaken when looking at patchwork, and originally only applied the
   patch removing the NPTL dependency, because it was available
   standalone, outside of any series.

 * You should use 'git format-patch -M' to enable rename detection. It
   would have made patch 1 a lot smaller, and easier to review.

Thanks a lot!

Indeed my bad, I was not sure if I may re-send only 1 patch so I asked
if that's ok but never got an answer here
http://permalink.gmane.org/gmane.comp.lib.uclibc.buildroot/99171

Nevertheless I understand that that's my fault and I'll try to not do
such silly things in the future, so thanks for this comment.

Hm, I didn't know about this actually.
I did "git mv" and believed that there's nothing else I may do to
simplify rename changes. Will do it this way next time.

No problem! Everybody learns progressively how to do things :)

I must confess that I don't actually don't know precisely how git
encodes renames. But basically, my understanding is that even if you do
"git mv", "git format-patch" will encode a rename as a complete removal
+ a complete addition, because that's the only way, in the traditional
patch format, to express a rename. However, by passing -M to git
format-patch, you tell git that it can generate a git patch, making the
assumption that it's git that will be used to apply the patch, and not
just the basic "patch" tool. In this case, it can encode the rename in
a smarter way.

Best regards,

Thomas

Easy, it doesn't. It just stores blobs and the old and new files will
share the same blob as they are identical. The rename detection is only
for how you want the commit to PRESENTED.

Indeed. You can enable it by default with something like:

git config --global diff.renames copy

Ah, yes, that's what I have in my ~/.gitconfig, which explains why I
never use "git format-patch -M" and still have proper rename detection
enabled for all the patches I send. Something I must have enabled years
ago, and I forgot about it.

Thanks for the clarification anyway,
