* There is a little code duplication. This will be moved to BFormat once
the time and datetime formatting is also moved out of BLocale
* The way to create a BDateFormat from a BLocale is still open for
discussion. I'm undecided between making BDateFormat a member of
BLocale, or adding a BDateFormat(const BLocale&) constructor.
* Adjust all users of the API.
A BGeolocation object can query an online service to get geolocation
and geotagging data:
* LocateSelf() tries to locate the machine it is running on, by using an
online database of wifi access points
* Locate() (not yet implemented) searches a BString and converts it to
lat/lon coordinates (reverse geotagging)
* Name() (not yet implemented) finds a suitable name for the given
coordinates (address, building name, or anything fitting).
The default service used is openbmap.org, which is freely available but
not very accurate. A request has been sent to Mozilla to use MLS
(Mozilla Location Services), which is a bit more accurate but needs an
API key. MLS is used for geolocation on FirefoxOS, for mobile phones
which don't have a GPS, and the data can be contributed by Firefox for
Android or the dedicated MozStumbler app.
Alternatively, Google Maps also provide the service, but wants
people to pay for it. Google Maps data is more accurate as all Android
devices contribute data to it.
All 3 services use the same JSON-based API: we send a list of reachable
Wifi APs (mac address and signal strength), and we get lattitude and
longitude information, and possibly extra data which will currently be
unused.
This can be used to implement HTML5 geolocation with reasonably accurate
results, but it can also be used in other places. For example
FirstBootPrompt could try to guess a list of most likely languages and
keyboard layouts from it (if wifi is working at install time, that is).
* Move default context management to BUrlRequest since some code
(including the testsuite) bypass the BUrlProtocolRoster.
* Introduce proxy host and port in BUrlContext
* Have BHttpRequest use the proxy when making requests
Comments to #9672 agree that there's really no need to
expose the dev_t handle, thus simplifying the API.
The dev_t handle, if required, can be retrieved via
BPartition::GetVolume() instead.
This patch adds user_access() which can be used to gracefully handle
page faults that may happen when accessing user memory. It is used
by arch_cpu_user{memcpy, memset, strlcpy}() to allow using optimized
functions from the standard library.
Currently only x64 uses this, but nothing really is arch specific here.

The kernel is allowed to use fpu anywhere so we must make sure that
user state is not clobbered by saving fpu state at interrupt entry.
There is no need to do that in case of system calls since all fpu
data registers are caller saved.
We do not need, though, to save the whole fpu state at task swich
(again, thanks to calling convention). Only status and control
registers are preserved. This patch actually adds xmm0-15 register
to clobber list of task swich code, but the only reason of that is
to make sure that nothing bad happens inside the function that
executes that task swich. Inspection of the generated code shows
that no xmm registers are actually saved.

Enable SSE as a part of the "preparation of the environment to run any
C or C++ code" in the entry points of stage2 bootloader.
SSE2 is going to be used by memset() and memcpy().

There is absolutely no reason for these functions to be in commpage,
they don't do anything that involves the kernel in any way.
Additionaly, this patch rewrites memset and memcpy to C++, current
implementation is quite simple (though it may perform surprisingly
well when dealing with large buffers on cpus with ermsb). Better
versions are coming soon.

The possibility to specify custom memcpy and memset implementations
in cpu modules is currently unused and there is generally no point
in such feature.
There are only 2 x86 vendors that really matter and there isn't
very big difference in performance of the generic optmized versions
of these funcions across different models. Even if we wanted different
versions of memset and memcpy depending on the processor model or
features much better solution would be to use STT_GNU_IFUNC and save
one indirect call.
Long story short, we don't really benefit in any way from
get_optimized_functions and the feature it implements and it only adds
unnecessary complexity to the code.

* Removes default mapping of a portion of the RAM (will be done
as needed)
* Passes on the page directory area to kernel, so on early vm init
the kernel can use the area for pagetable allocation.
* Leaves it to the platform to pass in physical memory range(s). This
will ultimately come from FDT.
* Fix long standing issue with allocation of the heap, potentially
causing other part of the bootloader to overwrite the heap.
* Implements pagetable allocator in kernel for early vm mapping.
This fixes the first PANIC seen, we now just get the same one later
on when the VM is up... more to come...
This reverts commit 3fbb24680c.
As I mentioned in #11131, this fix is not correct, and works around
the problem. The real reason was that arch_debug_call_with_fault_handler
was not working properly, so the fault handler went crazy.
With commit eb92810 that is fixed so this can be reverted.
This reverts commit 34dbbb65fd.
Instead, we can remove thos from HaikuBuildCompatibility and things will work fine, unless one try t build Haiku on BeOS (this isn't
supported anymore) or a very old Haiku which esdon't have those.
Pawel changed the implementation but I see no reason to make those available only from C++, so it must be an oversight.
Fixes building Haiku on Haiku which otherwise hits a mismatch in build compatibility headers.
If GCC knows what these functions are actually doing the resulting
code can be optimized better what is especially noticeable in case of
invocations of atomic_{or,and}() that ignore the result. Obviously,
everything is inlined what also improves performance.

Based on an earlier piece of source code of mine that parsed JSON into
QObjects, this JSON parser creates a BMessage tree.
Will be used by Stephan in HaikuDepot for communication with the web app.
* From now on, the gcc-specific system libraries (libgcc, libsupc++ and
libstdc++) are provided by separate packages built along with gcc:
- gcc_syslibs contains the shared libraries (libgcc_s.so, libsupc++.so and
libstdc++.so)
- gcc_syslibs_devel contains the static libraries and both c++ and gcc
headers
The shared libraries now make proper use of symbol versioning and there
are version-specific symlinks
* The buildsystem has been adjusted to no longer use the libraries and
headers from the cross-compiler, but use the ones provided by the
above-mentioned packages. The only exception is that the 32-bit libraries
required for the bootloader of the x86_64 architecture are still taken
from the cross-compiler.
* The new libstdc++.so contains program headers of type PT_RELRO (for
making segments read-only after relocation). While the actual feature
has not been implemented, the runtime_loader should now silently
accept (and ignore) those program headers.

- This allows a BMediaDecoder (e.g. FFMPEG Plugin) to communicate back format
changes to its clients.

- Backwards compatibility is taken into account and preserved by reducing the
relevant _reserved[] fields.
- Code changes that will actually make use of these extensions are due for the
following commits. As these structure extensions affect several Haiku
components (e.g. media_server, MediaPlayer, etc.) and third party apps (e.g.
StampTV, etc.) I refrain from committing them in one batch with this commit.
This should make it easier to track down bugs originating in this code
change.
(cherry picked from commit 806b6888d2dcf84b4934f8f137a48d3381864d1c)
* This is a header used by several parts of the code which should not
need to know about ELF symbol overriding and the fact that it is
optional.
* When the define is set, the methods will not be defined, but they
shouldn't be called, either
* This makes sure the memory layout of the class stays the same with the
define set or unset, and users can rely on it.
Fixes UnitTester on gcc2.
* Remove unneeded field fOutputHeaders and convert it to a local for the
only method that uses it,
* Don't return EOVERFLOW when flushing data from ZLib (the ZLib
decompressor returns this, but zlib docs states that this is NOT an
error condition).
* Replace unneeded temporary BNetBuffer of fixed size with BStackOrHeapArray.
Double checked BeOS R5 & Haiku R1/A4 and BTextView should be 356
bytes, somewhere since then we've added 4 bytes. So, this commit
reduces the class size from 360 back to 356 by removing 1 reserved
int32 (instead of 2).
I believe the class size changed in hrev46798 as a result of adding
2 bools (1 byte each padded out to 4 bytes).
Sorry for the noise.
In hrev46796 I added two new private methods: _PreviousLineStart(),
and _NextLineEnd() which increased the size of the class breaking
binary compatability because I forgot to decrement the reserved array.
This commit decrements the reserved array restoring the class size
to the original size fixing the binary compat issue.
Thanks Axel for noticing.
The order is updated so the virtual methods appear in the same order
that they did in BeOS R5 with methods new to Haiku added to the bottom.
Perform() moves up, all other methods move below GetDragParameters(),
the last virtual method in BeOS R5's TextView.h.
* receiveEnd is set in a different place in case of chunked transfers,
which would cause the decompressor to never be flushed.
* In the case of chunked transfers, we call Flush() without any input
data (to flush only whatever is remaining in the decompression buffer).
This causes ZLib to return Z_BUF_ERROR which is translated to
B_BUFFER_OVERFLOW. This is a non-fatal error and is expected behavior in
that case. Don't handle this as an error, and do use the extracted data.
Fixes various cases of missing the last chunk of a page (pastie.org,
Google search results, and more).
Accidentally renamed these in the header, rename them back to
match the cpp file. These param names might not be very good but
they match the struct variable names. They are private methods
anyway. No functional change intended in either commit.
Besides that this is a nicer interface, it allows us to get a the HPKG
header as a side effect of initializing the reader, thus preventing
seeking backward in the file. This makes "package recompress - <file>"
work.
* Prefix lock functions with __ to mark them as private. Add
forwarding macros to keep existing code working.
* Avoids symbol name clashes with kernel lock APIs, occuring when
using kernellandemu-lib in userlandfs. Thanks to Ingo for the
suggestion.
Until now we always declared in the HPKG header that the package file is
zlib compressed. For uncompressed files we would just store all
individual chunks uncompressed. Now we handle completely uncompressed
files slightly differently: We don't write the redundant chunk size
table anymore. The size savings are minor, but it makes the uncompressed
format read-streamable which may be handy.
* PackageFileHeap{Reader,Writer} as well as Package{Reader,Writer} and
their implementation and super classes do now internally use a
BPositionIO instead of a FD to access the package file. This provides
more flexibility needed for features to come.
* BPackageReader has already grown a new Init() version with a
BPositionIO* parameter.
Simple BPositionIO implementation using the POSIX API on a FD. In effect
similar to BFile, but more easily ported to kernel and boot loader (and
the FD is reusable).
* Add support for hubs in AllocateDevice().
* Prevent page fault in FinishTransfers().
* Set fCapabilityLength
* Correct in BIOS ownership code
* Fix context errors in _InsertEndpointForPipe().
* Update constants according to latest Specification (v1.1)
* Fix SMI code (reference

of xhci before ehci, to switch USB 2.0 ports before the ehci module
discovers them.

* Ingo copied the methods into a shared location, and then obviously
"forgot" to let BFS use them. As a side note for Ingo: the complete
error GCC reported was "std::fssh_size_t" not defined with the macro
wrapper as code location. The actual problem was a "using std::size_t"
in some C++ header that accidentally got included after the wrapper.
* The shared Query code is not yet used. That'll be done another time.
* Renamed BFS_SHELL define to FS_SHELL, such that QueryParserUtils can be
used in any file system shell, not just the bfs_shell.
* BCompressionAlgorithm is a base class for classes that provide
compression/decompression functionality. There are methods for
compressing/decompressing a single buffer and factory methods for
a compressing/decompressing input/output BDataIO.
* BZlibCompressionAlgorithm is a BCompressionAlgorithm implementation
using zlib.
The only purpose of this was to use the installed version of Errors.h,
which isn't strictly needed and create some annoyance when new error
codes are added.
Keep the brief description as a regular comment above each public method.
Leave the docs of private methods.
Some variable renaming mostly because of abbreviations.
Add documentation for all the public methods and app_info members and defines
that didn't have docs in the cpp file.
This allows adding new error codes to the libbe_build without breaking
the build on older Haiku versions.
Fixes the build for the newly introduced B_PARTIAL_READ and
B_PARTIAL_WRITE.
* FDDataWriter and ZlibDataWriter weren't used anymore.
* AbstractDataWriter was implemented only by PackageFileHeapWriter,
which was only used by WriterImplBase.
* Add a PackageFileHeapWriter::AddDataThrows() which has semantics
equivalent to the previously inherited WriteDataThrows().
