* heifsave: make it possible to use a specific encoder
* argument label: switch to leading capital letter
Co-authored-by: Kleis Auke Wolthuizen <github@kleisauke.nl>
* add VipsForeignHeifEncoder enum
* correct type
* implement reviewer feedback

* nsgifload: avoid minimise after mapping
Not reliable on Windows.
* nsgifload: prefer use of `VIPS_FREEF` macro
* Improve `test_descriptors.c`
* Only build `test_descriptors` when targeting Linux
* compiles
* note changelog
and switch to FATSTRIP (much quicker)
* don't duplicate header fields in fitssave
be careful not to set records twice in save
see https://github.com/libvips/libvips/issues/3113
* tiny polish
* libnsgif: update script: Fix to handle dir with no patches
* libnsgif: Update to latest upstream
Fixes loading of broken gifs with truncated final frame.
* nsgifload: Call nsgif_data_complete after data scan
This allows libnsgif to distinguish between awaiting more
data, and a broken truncated GIF. In the latter case we
can display what we have.
* reimplement threadpool
just a set of threads that get recycled
"ninja test" passes and dzsave seems to work, though pytest fails for
some reason
* clean up threading code a bit
move base stuff into thread.c, so we have a simple
thread -> threadset -> threadpool
layering
* start trying to revert g_threadpool
based on the original commit
* working!
nice low systime again
still need to repply cnages to threadpool.c since 80e0cc3d1
* reapply fixes from master
so threadpool.c is now up to date
* rename VipsThread as VipsWorker
a bit less confusing
* use a semaphore to count workers in a pool
* tidy up
* formatting
* dynamic threadpool sizing
based on counting the number of blocked threads in each pool
it works, but the improvement is not great :(
* add "concurrency" metadata item
so operators can hint threadpool size (dzsave especially)
* don't use thinstrip for small images
* add RGB mode to openslide
since flatten was taking 20% of CPU time for dzsave
* fix up rgb mode
now actually works
* make the tile buffer per thread
in the new openslideload rgb mode
* fix dynamic pool downsize
* mild refactoring
* fix the buffer system
oops, turned it off by mistake
* all done!
* revise changelog
* Update libvips/iofuncs/threadset.c

* LSan: add libMagickCore to suppression file
* Revert "Remove mutex lock for VipsThreadStartFn"
This reverts commit 41440491.
* add VIPS_MAX_THREADS
to set a hard limit on the threadset size
* Revert "Revert "Remove mutex lock for VipsThreadStartFn""
This reverts commit 77e8520966ba79194fff3b4e648bbd295cd5c260.
* remove sslock from sink.c
* move fixed threadpool build to init
not first use
* add some doc comments
* revert test suite threshold change
* add a test for MAX_THREADS
and move the test tmp/ area into the builddir
* limit VIPS_MAX_THREADS to sane values
* use tabs rather than spaces

* spngsave: ensure quantisation occurs last
i.e. after setting the metadata and phyiscal pixel dimensions,
since quantisation will overwrite the image.
* spngsave: avoid over-allocation of temporary buffer
For low-bitdepth write and palette-based output.
* Inverted order of TIFF tag writing when saving multi-page subifd pyramids to ensure that subifd pyramid layers are correctly tagged as reduced-image subfile type and not as pages
* Use if-else clause to avoid tag overwriting
We added a check that loader ->header() and ->load() methods set the
same dhint. This commit removes that check -- it's not possible to make
header and load match in all cases since images can take so many routes,
and can change between the two events.
If we see performance issues around inappropriate cache sizing again,
try to fix just those cases.
