FreeBSD 12's net80211 layer contains only 2 small KPI breaks from FreeBSD 11,
so we can upgrade it, apply those 2 changes to the drivers which are affected
(as the changes are in some lesser-used functions), and then upgrade all drivers
one at a time.
FreeBSD 12 has no major changes to the ifnet KPIs that constitute a
source compatibility break, save a single one related to locking
which doesn't really apply to us, and so we don't need to create
a "freebsd12_network" directory to work through the upgrades.
A few weeks back, I spotted in the Musl FAQ that they apparently ship
empty libm.a and libpthread.a files (https://www.musl-libc.org/faq.html),
which they said was for POSIX compatibility. A bit of digging got me to
http://pubs.opengroup.org/onlinepubs/9699919799/utilities/c99.html which
says:
> It is unspecified whether the libraries libc.a, libl.a, libm.a, libpthread.a,
> librt.a, [OB] [Option Start] libtrace.a, [Option End] libxnet.a, or liby.a
> exist as regular files. The implementation may accept as -l option-arguments
> names of objects that do not exist as regular files.
So to follow the letter of the law, we only need to have the "c99" command
accept these; however, it appears all Linux and BSD cstdlibs accept them
no matter what compliance mode is in effect.
Discussed with PulkoMandy. This will make HaikuPorts' job a lot easier...
- As suggested by Ingo, add libshared.a to the architecture name map.
This allows it to be linked by its short name like other frequently
used libraries.
- Adjust all Jamfiles referencing the lib accordingly.
The individual debug heap implementations are now exposed via a
structure of function pointers and a common frontend dispatches the
malloc and malloc_debug APIs through them.
The MALLOC_DEBUG environment variable can be used to select the guarded
heap by adding 'g', otherwise the debug heap is used as the default.
Consequently the separate libroot_guarded is not needed anymore and has
been removed.
To allow the use of environment variables this early, init_env_post_heap
has been added and the heap dependent atfork() moved there. This allowed
to fold the code of init_heap_post_env into init_heap so the former has
been removed.
The script runs the guarded heap allocation output through c++filt to
demangle stack trace symbols and filters out a list of known globals
that are never freed. It also allows to exclude further patterns
provided on the command line.
This adds libroot_guarded.so to the HaikuDevel package. It is the same
as libroot_debug with the debug heap swapped out for the guarded heap.
The guarded heap has some useful features that make it desirable to use
while having the disadvantage of a large memory and address space
overhead which make it unusable in some situations. Therefore the
guarded heap cannot simply replace the debug heap but should still be
made available. As the heap init needs to happen even before having
environment variables, the heap to use can not be chosen dynamically.
Exposing them through their own libraries is the next best thing.
* This is a very useful control, and 3rd-party apps should be able to
use it.
* But, there are planned improvements (making a better model/view
interface) which prevents making it part of the stable API yet.
* We install the headers for many things that are currently in libshared
(BColumnListView, BCalendarView, etc). So it makes sense to also provide
the lib in an "use at your own risk" way. Only the static library is
included, so apps linking against it should continue running on newer
Haiku versions even if the content of the lib changes.
* 3rd party application developers can now make use of those
experimental features without having to copypaste and fork the sources.
* Instead of separate variables, HAIKU_BUILD_TYPE is set to one of
'bootstrap', 'minimum' or 'regular'.
* Adjust uses of HAIKU_BOOTSTRAP_BUILD accordingly.
* All packaging architecture dependent variables do now have a
respective suffix and are set up for each configured packaging
architecture, save for the kernel and boot loader variables, which
are still only set up for the primary architecture.
For convenience TARGET_PACKAGING_ARCH, TARGET_ARCH, TARGET_LIBSUPC++,
and TARGET_LIBSTDC++ are set to the respective values for the primary
packaging architecture by default.
* Introduce a set of MultiArch* rules to help with building targets for
multiple packaging architectures. Generally the respective targets are
(additionally) gristed with the packaging architecture. For libraries
the additional grist is usually omitted for the primary architecture
(e.g. libroot.so and <x86>libroot.so for x86_gcc2/x86 hybrid), so that
Jamfiles for targets built only for the primary architecture don't
need to be changed.
* Add multi-arch build support for all targets needed for the stage 1
cross devel package as well as for libbe (untested).
* Deskbar now uses ~/config/settings/deskbar/menu_entries for its menu,
falling back to /system/data/deskbar/menu_entries, when the former
doesn't exist. The latter always exists and is a virtual directory
merging the deskbar/menu subdirectories of ~/config/settings/ and
<any installation location>/data/. So, if a package provides a
deskbar menu symlink, it is added automatically when the package is
activated. The user can add own menu items by putting stuff into
~/config/settings/deskbar/menu/, only use their own organization by
symlinking it to menu_entries, or do fun stuff by making menu_entries
a customized virtual directory.
* HaikuImage: No longer create any deskbar menu symlinks in the user's
settings directory. Instead add them to the Haiku package.
* OptionalPackages: At least for the optional packages that do have
hpkgs, no longer create deskbar menu symlinks in the user's settings
directory.
* Move all Deskbar settings files to ~/config/settings/deskbar/ and
drop the "Deskbar_" prefix.
* Also make use of new build feature rules.
* Since the hacky long_jump_buffer field has been removed from the
jpeg_error_mgr struct in the new package, the structure is now
wrapped in the JPEGTranslator code to achieve the same behavior.
We have to use actual targets that cause the respective download and
extract the packages. Otherwise the build fails when the packages
haven't been extracted yet.
* Add optional packages Zlib and Zlib-devel.
* Simplify the build feature section for zlib and also extract the
source package.
* Replace all remaining references to the zlib instance in the tree and
remove it.
