This way, we will avoid in the future any discrepancies between
languages set in the Windows installer and available translations (po
files in po-windows-installer/) because `make check`/`ninja test` will
fail.
We were loading 16-bit per sample SGI images as 8-bit
integer images even though we have had support for
16-bit integer for a long time now.
Changed to use 16-bit integer encoding now. Saw
this request a while ago on the gimp user mailing list.
Instead of only checking for the layer resources Lr16 and Lr32 make it
a loop and use the generic get_layer_resource_header to read all
resources.
We still need to figure out at a later time how to best handle these
resources.
For PSB images certain resources have 64-bit lengths.
Let's handle this transparently by adding a psd_version
parameter and depending on that and the type of
resource we decide if the length to read is 32 or 64-bit.
We also return the total header size. This way the
calling function can use that to determine the
remaining length.
Because we needed to check the signature when
loading the header we remove that check from
the load_layer_resource function since that
would be redundant.
Apparently layer height or width can be negative for certain
PSD layers that have the irrelevant flag set.
We move those checks down until after we have read that
flag and only validate if the irrelevant flag is not set.
Since the 1-bit conversion debug statements causes a huge amount
of info which can cause slowdowns when loading do it only when
explicitly setting it to IFDBG(4).
In certain places in a PSB file we need to read 64-bit
lengths where in a PSD we read a 32-bit length.
To make handling this easier we add a function that
determines if we need to read 4 or 8 bytes and
also handles converting the value from big endian.
Even though the current specs say max is 56 there
are sample files with more channels. Since there is
no reason why we can't handle more let's increase
the maximum to 99 for now.
I left the version I was using while testing, but this is obviously
wrong as we would always forget to update it (actually even now it was
wrong as it was producing an installer versionned 2.99.6 whereas it
should have been 2.99.7!). Instead let's grep the major/minor/micro from
the build system.
The goal is to make it easier to understand which pipeline is run when,
for future maintenance, and also to make it easy to trigger a specific
pipeline through Gitlab pipeline interface.
- Adding a patch sent to me by Sylvie Alexandre meant to help aalib
build on MSYS2 for Windows 32 and 64-bit.
- Additionally, add an additional patch from myself because it was still
not building properly.
- Also update the config.guess|sub files because the original ones (from
2001!) were just too old and not properly recognizing the host mingw
system (especially the 64-bit one apparently) in the MSYS2 CI jobs of
GIMP.
- Finally regenerate the whole aclocal/libtoolize/autoconf/automake
build system because these old files just don't play nice with recent
autotools though the source files still regenerate fine (despite with
some warnings, but nothing blocking).
- Add crt-git dependency because libws2_32 is in there.
- Use aalib-config (available at least in the last releases of libaa,
1.4rc5 from 20 years ago!). Especially important as the basic
AC_CHECK_LIB() test does not work in my tests on Windows builds
because some more libs are needed.
- Make sure file-aa is also built if AA_LIBS environment variable is
explicitly set. Prevous code was not working in such case (file-aa was
not built even with AA_LIBS set).
We had an autotools build stopping at `make check` and a separate one
for `make distcheck`. This just seems very redundant hence a waste of
resources.
So let's drop the job gimp-autotools-debian then add a `make check` step
to gimp-distcheck-debian.
Also as a side change, I move the cppcheck to being a scheduled job.
It's not such resource intensive job, nor did it take much time, yet
it's not like we use this information constantly. Moreover it never
fails anyway (so it's not like it gives much information on a per-commit
basis, unless we explicitly look into the resulting files) and with the
ability to run custom jobs whenever we want, this is far enough if
sometimes we need to generate the cppcheck analysis more frequently.
The rest of the time, having 2 jobs of this a week (our current
schedule) is far enough.
Run InnoSetup in the Windows CI to build the installer from both the 32
and 64-bit builds.
Current limitations:
- No installer signature yet.
- Dependencies will have to be checked more thoroughly.
- Apart from babl and GEGL, we may want to make custom builds of any
package which has a patch in build/windows/patches/ (Windows-specific
patches) and build/patches/ (all platform patches).
- Plug-in interpreters (Python, Lua…) don't work. This will need to be
looked at in detail.
Globally this first automated installer build works fine though, as I
could install it in a Windows 10 VM and GIMP ran fine! So it's a first
step towards fully automated releases for Windows.
With compression level "ultra64" for LZMA, default value is 65536, which
is far enough (the installer file was only 100kib bigger, it doesn't
make that big of a difference in the end).
With the original value, the CI build would fail with "Out of memory"
error.

Do not try to follow up on the installed ghostscript (otherwise we'll
always have to fix as MSYS2 packages get updated). Instead, just install
whatever is in the /share/ghostscript/ path (assuming there is data for
a single version, which should be the case, especially on a resetted CI
build) and excluding the /doc/ folder.
These files I'm adding are currently being requested by the installer
script, even though I'm not sure at all how much needed they are,
especially for some of them (because I could successfully create an
installer by just commenting these out in the installer script).
Having them at each commit is counter-productive, first because these
builds take so long and second because there seems to be quite few
Windows runners. So we end up constantly waiting for CI jobs from
previous commits (so we are just constantly waiting).
This is resource over-usage. So instead, I'll just set this in scheduled
jobs. For release preparation though, we'll have to set up a workflow
later to trigger these jobs off-schedule/on-demand (I can see there is a
Gitlab interface to do this), but this can wait for when the installer
is fully generated by the CI anyway.
Not taking a non zero length into consideration caused us to read from the
wrong location in certain cases and then fail loading.
Always use the specified length to go to the correct location. This is not
a guarantee that we will be able to correctly load the image but at least
we won't read wrong data from the wrong location.
Commit aba721ae68 fixed its intended bug but brought a new: each time
the preview was updated, a new display was created. This fixes this new
bug. Hopefully it's good now!
I'm still very unclear why exactly but it would seem that just queuing
the redraw with an idle function is not enough. At least on Windows,
Jacob was having cases where opening an image would get stuck unless the
mouse was moved (causing draw events most likely).
So let's use a timeout function instead. Probably no need to queue the
idle followed by the timeout function as we had before commit
4fee04b839. Instead just directly queue a draw if relevant, then run the
timeout at regular interval (marching ants speed).
