The documentation file (which PulkoMandy only merged today) was created
over a year ago from a short conversation I had with him, and by now
a lot of its information is already outdated or has been merged into
comments in the driver already (specifically, the notes at the end about
error messages no longer apply as there are different ones, and the
bugs causing those errors have since been fixed.)
A few of the statements in it were not noted in the driver, though,
so I have added those as comments.
This is the partitioning system used on sparc machines.
Confirmed working with a Solaris install iso image.
Added to the haiku package for sparc and to haiku_extras for other
architectures.

After this patch, "UnitTester BSymLink" passes.
BSymLink::ReadLink() in BeOS would always return the length of the
link unless an error occurred. Before this patch, Haiku instead seemed
to emulate posix readlink() behavior, returning the number of bytes
copied into the output buffer.
BeOS also did not guarantee that the string written into the output
buffer is NULL terminated if the output buffer cannot contain the
entire link contents, but the Haiku implementation does since it is is
a basic safety issue.
This patch fixes this and updates the Haiku API docs to describe the
behavior explicitly.
Fixing this required changing behavior in bfs_read_link, which
required changes in many more places.
docs/user/storage/SymLink.dox:
src/kits/storage/SymLink.cpp:
* Don't return B_BUFFER_OVERFLOW if the provided buffer is not large
enough to hold the link contents.
* Update documentation to clearly describe behavior.
src/add-ons/kernel/file_systems/bfs/kernel_interface.cpp:
* Change bfs_read_link() to always return the link length. This is
called by common_read_link in the VFS, which is called by
_kern_read_link().
src/add-ons/kernel/file_systems/btrfs/kernel_interface.cpp:
src/add-ons/kernel/file_systems/exfat/kernel_interface.cpp:

src/add-ons/kernel/file_systems/reiserfs/Volume.cpp:
src/add-ons/kernel/file_systems/reiserfs/Volume.h:
* Update the implementation of read_link for these filesystems. Some
of them were incorrect, and some had just copied the posix behavior of
bfs from before this patch.
* Use user_memcpy in ext2_read_link()
* Use user_memcpy in nfs fs_read_link()
* Use user_memcpy in reiserfs StreamReader::_ReadIndirectItem and
StreamReader::_ReadDirectItem
* Remove unused method Volume::ReadObject in reiserfs.
src/add-ons/kernel/file_systems/packagefs/nodes/UnpackingLeafNode.cpp:
src/add-ons/kernel/file_systems/packagefs/package_links/PackageLinkSymlink.cpp:
* Update UnpackingLeafNode::ReadSymlink and
PackageSymLink::ReadSymLink() to set the bufferSize out parameter to
the symlink length. Both of these are called by
packagefs_read_symlink.
* Use user_memcpy
src/add-ons/kernel/file_systems/netfs/client/netfs.cpp:
* netfs seems mostly unimplemented. Added a FIXME note for future
implementers so that they know to implement the correct behavior.
src/system/libroot/posix/unistd/link.c:
* readlinkat() was just wrapping _kern_read_link() because before this
patch it had expected posix behavior. But now it does not, so we
need to return the number of bytes written to the output
buffer.
src/build/libroot/fs.cpp:
* Update _kern_read_link() in the compatibility code to emulate the
Haiku behavior on the host system. This is done by using an
intermediate buffer that is guaranteed to fit the link contents and
returning its length. The intermediate buffer is copied into the
output buffer until there is no more room.
src/tests/kits/storage/SymLinkTest.cpp:
* This patch also resolves some test failures similar to those
resolved in ee8cf35f0 which fixed tests for BNode. The tests were
failing because Haiku's error checking is just better.
BeOS allowed constructing a BSymLink with BSymLink(BDirectory*,
const char*) with the entry name of "". The same is true of the
equivilant SetTo() method. The BSymLink object will appear valid
until you attempt to use it by, for example, calling the ReadLink
method, which will return B_BAD_VALUE.
Haiku does a more appropriate thing and returns B_ENTRY_NOT_FOUND,
for this constructor and the equivilant SetTo(BDirectory*, const
char*) method. This patch fixes these test assertions to match Haiku
behavior.
docs/develop/file_systems/overview.txt:
* Add notes for future filesystem driver implementers to call this
mistake when implementing fs_vnode_ops::read_symlink.
docs/user/drivers/fs_interface.dox:
* Fix documentation for fs_vnode_ops::read_symlink

Get enough of the mmu working to be able to allocate memory.
Unlike on PowerPC, we get both address and size as 64bit values. So
adjust of_region to allow this.
Also unlike the PPC port, we do not drive the hardware directly, instead we
rely on the openboot primitives to manage the translation table. This
allows staying independant of the hardware, which is a good idea at
least for the bootloader (we can do actual hardware things in the
kernel)

We have quite a few GSoC projects around this, it would make sense to
have some documentation for people attempting them.
Add some generic overview of filesystems and how to test them.
I didn't do anything with sparc for a few weeks (you don't want this
machine running when temperatures already are over 30°...), and I wastd
some time finding back some of the useful information, such as commands
to boot and debug, load and execution address of the bootloader program,
etc. So let's keep these in the documentation directory.

* kernel/ports is now kernel/arch, like it is in src/system.
SPARC documentation is now in there, too.
* VM files (these are rather outdated) are now in kernel/vm.
* SCSI ASC info removed, this is easily available online and

- Add 128 bit long double support from current glibc and a few headers
they need
- Move the existing 80 bit float support in a sub directory of generic,
it is not universal to all archs (see file added in docs/develop/arch).
Also include some new .h files for x86 that are needed after these
changes (from newer versions of the glibc).
- Adjust Jamfiles for m68k, x86 and x86_64 to use the 80bit format
- Do not adjust arm jamfiles, it was wrongly using 80bit long double and
should be fixed to use 64bit instead (which means the double functions
can be used with aliases)
- Do not adjust powerpc jamfiles, because it uses yet another format and
we build it without long double support anyways.
Note that I moved only the files that were creating compile errors,
quite likely more of the s_* and e_* files need to be moved to the
specific directories, see glibc list here:

This change is a reshuffle of the backend processing involved in the
aquisition of data from servers including the pull-down and load of
HPKR data as well as the pull-down and load of data from the
HaikuDepotServer (HDS) system. The driver for this change is to
implement an initial implementation of a progress bar for the
loading of data as the application starts.
The following are notable changes;
* Removed some previously attempted 'functional style' logic in the
model which didn't fit well with C++
* Use of the base-url in the logical mapping from HDS and HD data is no
longer required and has been removed
* Some logging has been improved making it clearer which part of HD
is producing the logging which in turn helps with debugging issues
* List class has been modified to more cleanly support sorted lists
and binary searches; tests have also be updated accordingly
* Reorganise and tidy-up of the data-loading processes' structures
* The local repository update (HPKR) and data-load occur in background
processes now in the same system as the HDS data-load - this has been
crudely shifted from the MainWindow to new Processes and incorporated
into the background processing system
* The 'state-machine' background process runner is now replaced with a
'coordinator' style approach that can more easily handle the new
processes related to HPKR loading.
* Progress for loading processes is shown in the main window in the
WorkStatusView - this is flickering a bit, but basically works
* Added some documentation regarding how Processes work in the system
* The "Refresh Repositories" menu item now also updates data from HDS
* The "Refresh Repositories" menu item is disabled when the background
processes are running that update the repository data
Some further refinement would be good, but this change is large enough
for one round of improvements. There is an issue that the status bar
is used for screenshot display as well as this data-loading, but that
was the case before so it is something that can be dealt with later if
it is a problem.

John's revert of my removal commit dragged back a bunch of cygwin/sunos
cruft, as well as re-adding RegExp.cpp to the host libshared, that we don't
need.
Instead, remove this and add libgnuregex_build to just the tools/keymap
link alongside the FreeBSD gnuregex case.
Now vaguely follows the tree structure of "src", with the exception of
directories that described subsystems spanning more than one "kit" or
"server" (e.g. "media", "midi", "bluetooth") -- these have been left as their
own top-level directory within docs/develop.
It was needed on macOS for a time when BUrl used regexes for parsing.
Now it does not, and so we can remove libshared's RegExp from build
libshared, and thus also libgnuregex.
The Interface Kit is long since "99% functional", so lists of modules
with what's-implemented-what's-not are not really helpful anymore.
The one (rather lengthy) file describing the unit testing system
set up by the IKTeam is indeed useful, so keep that.
The only thing of any real use in this directory was the Be Newsletter
article, and the objdump from BeOS R5 (at least I guess that's what it is...)
so I kept those.
We bundle bitstream charter as a default font to use when nothing else
