* yuck, glibc uses yet another version of mbstate_t (__c_mbstate_t),
adjusting this to match the other glibc-internal version (__mbstate_t)
fixes another crash triggered by fwide_test.
* instead of unification, we now keep both our and glibc's fields
separate in order to allow for both our code and glibc's to use
such a struct at the same time (independently)
* _IO_USER_BUF was being used to indicate a user-owned buffer without
taking into account that there are two of those: one for the normal
and another one for the wide version of a stream. Backport
_IO_FLAGS2_USER_WBUF from current glibc version to fix that.
* add Wcscoll() and Wcsxfrm() ICU locale backend
* provide implementations of wcscoll() and wcsxfrm() that are using
the respective methods of the locale backend
Mostly done because olta want less dependency on glibc.
It should also make porting a tiny bit simpler.
Testresults, mean values on Haiku from libMicro:
* with glibc: strlen_10: 0.03859S, strlen_1k: 1.67075S.
* with strlen.cpp: strlen_10: 0.03854S, strlen_1k: 1.66938S.
So at least on my machine it's possible to beat glibc ;)
* Use TimeZone::SHORT specifier instead of SHORT_COMMONLY_USED, since
the former yields more appropriate (textual) values. Strangely enough,
it used to be the other way around, which is why we didn't used SHORT
in the past.
* Glibc declares and uses its own version of mbstate_t, which is
incompatibly with our own. Mix our own fields into glibc's
mbstate_t, such that the two structs are compatible.
* make room in mbstate_t for containing an ICU-converter's state
(well, in fact the whole converter object)
* adjust libroot's locale add-on to clone converters into a given
mbstate_t directly
* adjust ICUThreadLocalStorageValue to contain the converter pointer
instead of a converter-ID (if the converter is related to an
mbstate_t, it points into the mbstate_t).
* adjust users of converters to directly use converter pointers
instead of ICUConverterRef
* drop now unused ICUConverterManager and ICUConverterRef
* update gcc4 optional package
This brings our multibyte implementation into a fully working state,
both non-ascii and non-8-bit characters can now be handled normally
in the Terminal, i.e. this finally fixes#6276.
N.B.: Since the size of mbstate_t has changed, everything (including
the compiler!) needs to be rebuilt.
* the reference to MB_CUR_MAX requires stdlib.h
* if an conversion error occurs, the returned src pointer must point to
the character that triggered the error
* src was sometimes accessed incorrectly (needs double dereference)
* the source pointers may only be adjusted in case there is the
destination pointer is not NULL
* add MultibyteStringToWchar() to ICU locale backend
* implement mbsrtowcs() and mbsnrtowcs() on top of
MultibyteStringToWchar()
* drop respective glibc files
* Not including malloc.h caused the memalign() signature to not be a C
signature, therefore leading to linking errors. Fix the missing
include and explicitly add extern "C" as well.
* Some remaining asterisk style cleanup.
The guarded heap uses mprotect() to protect freed/unallocated pages so
that any access to such a page results in a segfault. It also installs
a segfault handler that in such an event prints some info about the
accessed page and then calls the debugger with a meaningful message.
It implements the same interface as the debug heap so it can simply be
swapped out by changing the Jamfile. As it doesn't support most of the
extra debug features (wall checking is obviously superfluous, but it
also doesn't help in leak checking) and as it is hugely space
inefficient I left it disabled for now.
Bring the changes that aren't package management related and the ones
that are but don't take effect as long as they are ignored by the build
system into the master.
Summary of changes:
* Introduce private header <directories.h> with constants for a good
deal of paths that should usually be retrieved via find_directory().
* Replace hard-coded paths by using find_directory() or the
<directories.h> constants (e.g. in drivers and the kernel).
* Add find_directory() constants needed for package management.
* Add __HAIKU_ABI_NAME and B_HAIKU_ABI_NAME macros.
* src/apps/deskbar: BeMenu.* -> DeskbarMenu.*,
DeskBarUtils.* -> DeskbarUtils.*
* Change deskbar menu settings directory from ~/config/be to
~/config/settings/deskbar.
* Other smaller cleanups, changes, and fixes.
* this avoids spurious errno changes leaking into application code,
which could become confused - i.e. 'rm' on a gcc4 build would always
prompt for confirmation
I spend a couple of hours hunting down the behavioural difference
between gcc2- and gcc4-builds and it turns out that the reason for that
is that gcc4's libstdc++-code initializes its own locale data via the
POSIX calls, which trigger (correct) errno value changes, which were the
ones leaking into application code.
* add errno_private.h, which defines the __set_errno() macro with
and without tracing
* instead of setting errno manually, all libroot's code now invokes
__set_errno(), which makes it much easier to trace changes to errno
* redirect glibc's use of __set_errno() to our own version
* update copyrights of locale backend files
Multibyte-support has been rewritten to use ICU as backend.
While this does not necessarily work properly in every aspect
(e.g. the shell still has [different] problems with multibyte-
characters now), it does fix#6263 and #7700.
