Rather than introducing a local copy of the

Bryce Harrington 03793e3998 Revert "config-parser: Catch negative numbers assigned to unsigned config values"
The reduction in range limits does have an effect for color values,
which are expressed as hexadecimal values from 0x00000000 to
0xFFFFFFFF.  By limiting the range to INT_MAX, color values of
0x80000000 and up are in fact lost.

This reverts commit 6351fb08c2.

Bryce Harrington 375759e636 Require base-10 for strtol() calls
The third arg to strtol() specifies the base to assume for the number.
When 0 is passed, as is currently done in option-parser.c, hexadecimal
and octal numbers are permitted and automatically detected and
converted.

This change is an expansion of f6051cbab8
to cover the remaining strtol() calls in Weston, where the routine is
being used to read fds and pids - which are always expressed in base-10.
It also changes the calls in config-parser, used by
weston_config_section_get_int(), which in turn is being used to read
scales, sizes, times, rates, and delays; these are all expressed in
base-10 numbers only.

The benefit of limiting this to base-10 is to eliminate surprises when
parsing numbers from the command line.  Also, by making the code
consistent with other usages of strtol, it may make it possible to
factor out the common code in the future.

Bryce Harrington 6351fb08c2 config-parser: Catch negative numbers assigned to unsigned config values
strtoul() has a side effect that when given a string representing a
negative number, it returns a negated version as the value, and does not
flag an error.  IOW, strtoul("-42", &val) sets val to 42.  This could
potentially result in unintended surprise behaviors, such as if one were
to inadvertantly set a config param to -1 expecting that to disable it,
but with the result of setting the param to 1 instead.

Catch this by using strtol() and then manually check for the negative
value.  This logic is modelled after Wayland's strtouint().

Note that this change unfortunately reduces the range of parseable
numbers from [0,UINT_MAX] to [0,INT_MAX].  The current users of
weston_config_section_get_uint() are anticipating numbers far smaller
than either of these limits, so the change is believed to have no impact
in practice.

Also add a test case for negative numbers that catches this error
condition.

Bryce Harrington f6051cbab8 option-parser: Require integer option string values to be base-10
The third arg to strtol() specifies the base to assume for the number.
When 0 is passed, as is currently done in option-parser.c, hexadecimal
and octal numbers are permitted and automatically detected and
converted.

In weston and the weston clients and tests using option-parser.c, the
options are all things that can be expected to be specified in base 10:
widths, heights, counts, scales, font sizes, ports, ttys, connectors,
etc.  The subsurfaces client uses two modes, limited to values 0 and 1
only.  The zuc testsuite has a --random parameter for specifying a seed,
which is the only option where using hexadecimal or octal numbers might
conceivably happen.

The benefit of limiting this to base-10 is to eliminate surprises when
parsing numbers from the command line.  Also, by making the code
consistent with other usages of strtol/strtoul, it may make it possible
to factor out the common code in the future.

Bryce Harrington cbc053781e config-parser: Improve error checks for strtol/strtoul calls
Check errno, which is set of over/underflow, out of range, etc.  Also
check for empty strings (the usages covered in this patch already also
cover the case where there are non-digits present).  Set errno to 0
before making the strto*l call in case of pre-existing errors
(i.e. ENOTTY when running under the testsuite).

This follows the error checking style used in Wayland
(c.f. wayland-client.c and scanner.c).

In tests, also check errno, and add testcases for parsing '0'.

Pekka Paalanen 289fdeb019 tests: convert reference image loader to pixman
This rewrites load_surface_from_png() to load_image_from_png(), to
return a pixman_image_t instead of a struct surface.

A loaded image has no need for wl_buffer or wl_surface or any of the
associated attributes. This is part of unifying to make everything use
pixman_image_t.

cairo_surface_flush() is added, because Cairo documentation for
cairo_image_surface_get_data() says you have to flush after drawing,
before using the data. It is unclear if loading a PNG counts as drawing,
so stay on the safe side.

load_image_from_png() now pays attention to the pixel format returned by
Cairo, which seems to come out as CAIRO_FORMAT_RGB24 in
internal-screenshot-test, not as CAIRO_FORMAT_ARGB32 as expected. I do
not know if Cairo actually guarantees the x8/a8 channel to be 0xff for
RGB24, but better to not trust it. Therefore the image is explicitly
converted to a8r8g8b8 as needed. This also adds support for loading A8
and RGB16_565 images, provided that Cairo delivers them.

The cairo surface is now wrapped directly into a pixman_image_t. If the
pixel format conversion is not needed, this eliminates a copy of the
image data. The Cairo surface will get automatically destroyed with the
Pixman image.

Pekka Paalanen 47d68dae59 tests: rewrite check_surfaces_*() API
check_surfaces_geometry() is removed as it was not used by anything, and
unlikely would be.

check_surfaces_equal() is merged into check_surfaces_match_in_clip(),
passing a NULL clip means to compare whole images.

check_surfaces_match_in_clip() is converted to work on pixman_image_t
instead of struct surface. The function is only concerned about
comparing images in memory, and does not care about a wl_buffer or a
wl_surface.

The verbosity of image comparisons is greatly reduced. An image mismatch
no longer prints a flood of raw pixel values. This will be replaced
later with a function writing out an error image instead.

Degenerate comparisons are no longer accepted, be that clip outside
images or zero area. Those are an indication of a programmer error.

The pixel format assumptions are made more visible in the code.

A new internal helper image_check_get_roi() computes and verifies the
area to be compared. Image iterator helper makes it simpler to write
manual pixel-poking loops.

Pekka Paalanen 924cd948ee tests: introduce struct buffer for client-helper
We are growing more tests that need to handle buffers, both just images
and wl_buffers. Particularly the screenshooting facility needs these.
Currently everything is in struct surface, which contains more than we
need. It is a bit messy.

Create a new struct buffer to encapsulate the image representation, the
wl_buffer, and enough information to tear it all down (munmap) so we
don't have to leak everything. Some tests might start doing things in
loops, and leaking would accumulate.

Instead of inventing our own image representation, use pixman_image_t.
It is a well-tested library worth using, and we already rely on it in
other places.

This makes the tests depend on Pixman, which requires the fix for
building buffer-count, which would otherwise not find pixman.h.

The new create_shm_buffer_a8r8g8b8() creates an image with an explicit
format, and pixman_image_t keeps track of it. And stride and size and
data. This implementation is still a little hacky due to calling
create_shm_buffer().

A very new thing is buffer_destroy(). Previously we didn't really free
any buffers. It is not a problem when the process will exit soon anyway,
but it may become a problem if tests start iterating things.

Manual memset() on a image is converted to a pixman action, just to show
how to do it properly with pixman.

Stride and pixel format assumptions still linger all around, but those
are for another patch.

Ucan, Emre (ADITG/SW1) 37d25bb1e0 ivi-shell: implement surface_on_many_layer test
A surface can be added to many layers.
This test is implemented to test this use-case
and the correct behaviour of get_layers_under_surface
API.

Ucan, Emre (ADITG/SW1) 5e8d55da69 ivi-shell: introduce ivi_layout_view
This patch introduces ivi_layout_view data struct,
which is a wrapper of weston_view.

There is always only one ivi_layout_view for an
ivi_layout_surface and ivi_layout_layer pair.
A surface could have many views with different
geometry and transformations, so that a surface
can be shown on:
	1. On many screens
	2. On the same screen with different positions

The geometry of a view is modified, when properties of
its layer are changed through ivi_layout_interface.
Users of ivi_layout_interface does not have direct access
to ivi_layout_view structure.

v2 changes:
	1. Use ivi_view_is_rendered function instead of
	   active member
	2. Add descriptions to introduced members of
	   structs

Ucan, Emre (ADITG/SW1) d97f10081e ivi-shell: add surface_created listener after launchers
Add surface_created listener after the initialization of launchers.
Otherwise, surfaces of the launchers will be added to the application
layer too.

This does create a race where we might miss some surfaces that get
created before the UI client signals ready, but it was agreed the race
is not significant. You cannot use the launchers before the UI is ready,
and someone using systemd integration to launch clients in parallel to
Weston with ivi-shell and hmi-controller is unlikely. After all,
hmi-controller is just a demo.
