Merge lp:~dandrader/geis/lp984069 into lp:geis

[Daniel d'Andrada]

GeisTouches from direct devices should be in window coordinates. Have this also documented in geis.h

The fix for bug #978378 in Unity depends on it.

This should be tested by someone with a touchscreen device along with the fix for bug #978378 (lp:~dandrader/unity/direct_device) to verify that those modifications indeed get bug #978378 fixed.

[Stephen M. Webb (bregma)]

The code change looks OK. I built and tested with a touchscreen, and nothing appears to be broken, but I don't think that's really a valid test of this change. Is there a better interactive test?

[Chase Douglas (chasedouglas)]

I tested the branch and everything seems to work appropriately. In the unity branch, the unity bug #978378 seems to be fixed.

We just need tests in geis now.

[Daniel d'Andrada (dandrader)]

I would make it use Google Test istead of Check Framework but in utouch-geis GTest is quite entangled with xorg-gtest and integration tests (ENABLE_INTEGRATION_TESTS).

[Chase Douglas (chasedouglas)]

As far as I understand, the gtest issue is merely that we need to make the autotools stuff know about gtest for unit testing. I would prefer to fix that issue now and continue to use gtest.

Otherwise, I'm ok with this for now. I think we may want to split the mock out into a separate project in the future, maybe using a mock framework like google-mock to make things easier.

Took libgtest.a out of libgtest_geis.a and made the regression test of this bug GTest based instead of Check based.

Ready for a new review.

[Chase Douglas (chasedouglas)]

* xorg-gtest.m4 shouldn't be modified. It comes from upstream xorg-gtest and may be replaced by a newer version from an updated xorg-gtest automatically by aclocal --install. IIRC, I think it may also be always replaced by our packaging since it uses aclocal --install --force.

Since _CHECK_GTEST is meant to be an internal implementation detail of xorg-gtest.m4, I suggest copying it to a new file m4/gtest.m4 and removing the leading underscore.

* libgtest_geis_a_CPPFLAGS still needs $(GTEST_CPPFLAGS). If the gtest headers are installed somewhere other than a standard location, GTEST_CPPFLAGS will have the -I<header path> option. This will be needed for building xorg-gtest too. Likewise for gtest_geis2_grail_backend_CPPFLAGS.

* libgtest_geis_a_LIBADD should add the libgtest.a file instead of an intermediate object file. I don't know if that will work, but the .o file is sort of an autotools implementation detail. This may also remove the need for libgtest_geis_a_DEPENDENCIES.

* libgtest doesn't need to be built with --std=c++0x. xorg-gtest doesn't need to built with it either. I also don't know why TEST_ROOT_DIR is defined for both gtest libs. I think it was a copy/paste error.

* PRINT_FAILURE_AND_RETURN isn't necessary. All you need is ADD_FAILURE() << [message]; The file and line will be printed automatically, and the function return automatically.

* I like the idea of MOCK_PRINT. I think it duplicates the geis logging, though. Why not use geis_debug()? I know this means you can't enable mock printouts without geis debug printouts, but I think that's ok. If you're debugging at this level you might be setting GEIS_DEBUG=3 anyway. If you have a standard format where something like "XMOCK: " is prepended to the message, it will be easy to grep or grep -v on it.

[Stephen M. Webb (bregma)]

(1) m4/xorg-gtest.m4 is actually a convenience copy of a source file belonging to another package and will likely be overwritten at build time. I would suggest the CHECK_GTEST macro be hoisted into its own .m4 file so it doesn't get trampled: it's already renamed so there shouldn't be a conflict.

(2) Not sure why you did all the fancy wrangling in testsuite/gtest/Makefile.am to provide multiple libraries instead of just including the xorg-gtest sources conditionally on ENABLE_INTEGRATION_TESTS. Could you make your reasoning explicit?

(3) Why reorganize testsuite/geis2/Makefile.am? Traditionally all the build targets go at the top (eg. *_PROGRAMS) and the detailed rules for building them come later, rather than the other way around. Granted, that tradition started because automake required it, but following convention makes it easier from someone who sees a lot of Makefile.ams to follow unfamiliar code. Could you make your reasoning for this explicit?

(4) If you're changing testsuite libraries around anyway, would it be possible to consolidate all support libraries used in the testsuite (gtest, mocks) into a single subdirectory? It would simplify the Makefile.ams used in the various test suites. Feel free to argue this.

geis_debug() is not a public symbol exported from libutouch-geis.so. It is not available for any part of the testsuite except the libutouch tests (which are internal unit tests).

Ok. What about printing if an env var is set, like MOCK_DEBUG? I'm not a
big fan of preprocessor macros enabling optional functionality. It's not
easy to figure out whether something has been compiled with the
functionality or not.

Me neither, but that was the easiest way and I didn't think it was worth to invest time into making a fully fledged solution.

I like when all code regarding a library/program is together in a single block instead of intertwined with code for other libraries/programs. I find that arrangement easier to read and maintain. But as with coding style, it's mostly a matter of personal taste.

That's another way of doing it. But I prefer the separation method since "That way we can have tests that depend on gtest but not on xorg-gtest" and therefore tests can link against only what they are going to use. Tests that use xmock will use gtest but never xorg-gtest, evemu or the fixtures included in libgtest_geis.

I personally find it a bit messy to have the sources of several separate, independent, binaries (programs of libraries) living together in the same directory. It can easily result in a cluttered directory listing and Makefile.am.

But you know that for the last 40 years or so linkers only pull objects out of archives if they're used, so the only
difference between using a single library and using multiple libraries is one of increased maintenance cost and
confusion about which library to use?

GeisTouches from direct devices should be in window coordinates

GeisTouches provided by gesture events (GEIS_EVENT_GESTURE_BEGIN,
GEIS_EVENT_GESTURE_UPDATE and GEIS_EVENT_GESTURE_END) should be in window
coordinates if they come from a direct device (e.g. touchscreens) and in
input device coordinates when from indirect devices (e.g. touchpads/trackpads).

Have this also documented in geis.h

They were coming always in device coordinates.

ADD_FAILURE() does print the file name and line number but it does *not* return. Therefore a wrapping macro is still needed. So I removed the printf() command and renamed the macro.

Ahh, I remembered wrong. You want FAIL() << [message]; It's just like
ADD_FAILURE() except that it causes the function to return. It's
analogous to ASSERT_*() vs EXPECT_*().

gtest_geis2_grail_backend_CPPFLAGS still has --std=c++0x.

FAIL(), like ASSERT_*(), can only be used from within functions that return void. That's why I have to stick with ADD_FAILURE().

I needs --std=c++0x because it uses c++0x stuff (like nullptr and range-based for loops)

Ahh, yes, that would be an issue.

This is a bit bike-shedding, but I would prefer to unroll the macro
since it's two simple lines. I think it would make the code easier to
read. However, I'm ok with it as is.
