* Was leaking fQueuedJobs on destruction.
* fHaveRunnableJobSem implementation was not completed; it was never
released.
* Added Pop() variant that is a bit more flexible, and allows for a
timeout as well as waiting even when the queue is empty, and can
return a status code.
* Fixes sharing semantics, so non-shared semaphores in non-shared
memory do not become shared after a fork.
* Adds two new system calls: _user_mutex_sem_acquire/release(),
which reuse the user_mutex address-hashed wait mechanism.
* Named semaphores continue to use traditional sem_id semaphores.
* Put it in the BSupportKit namespace, following the style introduced
with the package kit for now.
* The BSupportKit::BJob class no longer knows about the package kit's
Context class. However, the BPackageKit::BJob class does.
* Due to the namespace juggling, a lot of files had to be touched.
* The JobQueue class remains private.
* Due to the way Haiku is built on itself, you cannot build this change
under Haiku with an older release.
* When you receive a message from a KMessage, and reply to it,
it will automatically reply as KMessage, too.
* This allows to communicate with BLoopers from within the kernel
or libroot.so.
"Renaming" means the icu namespace is suffixed with the version number,
atm icu_55. Using "renaming" allows to use two different versions of ICU,
thus easing upgrades. For instance haikuwebkit uses a current version of ICU,
while the system uses a newer one after an upgrade.
* Replace all uses of the icu namespace in our public headers, with a macro
defaulting to icu. As the namespace is only used for private fields pointers,
there should be no impact.
* Locale kit *.cpp have to import the macro from <unicode/uversion.h> *before*
including any locale headers. Ditto for a Time preferences cpp file. This way,
the correct current icu namespace is referenced.
* Fixes bug #12057.
Those return uintNN_t types instead of our own types,
but uint32 for example is long while uint32_t isn't,
giving some trouble with the PRI* macros for example on PPC.
It seems like glibc also has paths.h and m4 fails to bootstrap
without _PATH_BSHELL.
This file really needs some cleanup btw, since most is actually
irrelevant or incorrect for Haiku.
The AddOnManager was in the global namespace, clashing with application
classes with the same name.
The input_server has an AddOnManager of its own. When the
shortcut_catcher filter was loaded by said AddOnManager, it in turn
loaded libgame.so, which in turn loaded libmedia.so, where an
AddOnManager was created for the global AddOnManager instance in
libmedia.so. Unfortunately the wrong AddOnManager, the one from the
input_server, was created. This lead to two AddOnManagers being active
in the input_server which very well could be responsible for #11049
and #11280.
This was a regression since the move of the AddOnManager from the
media_server to libmedia.so in hrev47086. This also fits with the two
tickets.
I actually noticed the problem when debugging the shutdown process of
the input_server, where the destruction of the wrong AddOnManager
caused a deadlock with itself.
* Do not define the symbols by default, as they are not in the default
libraries.
* Adjust jamfiles of all code using BSD extensions to define
_BSD_SOURCE.
* This makes Haiku slightly more compliant to standard C/POSIX.
It works analoguous to BView::RemoveSelf(), i.e. it removes itself from
the parent (layout in this case) and returns whether or not it had and
was successfully removed from said parent.
The BNetworkRoute class manages a route_entry and the sockaddr's
associated with it. It replaces the direct use of route_entry in the
BNetworkInterface API.
Using route_entry is fragile and inconvenient as it only holds pointers
to the sockaddr's. When getting a list of routes from the kernel, each
route_entry is set up so that its pointers point into the single flat
buffer that is passed around. Creating a copy of the route_entry and
then deleting the flat buffer makes the pointers in the copy stale.
Returning these route entries therefore always lead to a use-after-free
when they were eventually used.
BNetworkRoute also takes over the code and functionallity of getting
routes from RouteSupport. The corresponding method in BNetworkRoster is
replaced by a static method in BNetworkRoute.
Also distinguish between the default route and gateway of an interface.
GetDefaultRoute() now gets the default BNetworkRoute for the interface
while GetDefaultGateway() gets the associated gateway address within
that default route. Adjust network preferences panel to this change.
Note that we currently only seem to have per interface default routes
and not an actual global default route. This was already the case before
these changes and I did not further investigate what this means.
It can be used to get a stack trace of the current thread. Note that
this works by walking frame pointers and will not produce anything
useful if an application is compiled with the frame pointers omitted.
The stack base and end addresses have to be provided as arguments and
are used to check that the frame pointers fall within that range. These
values are thread specific and can be retrieved with get_thread_info().
No other sanity checks (like checking for loops in the linked list) are
done.
This is a simplified rewrite of the stack trace code from the kernel
debugger.
As this code is common to x86 and x86_64 but is not generic across
architectures I introduced x86_common as a directory to put such
sources.
Extend the get_nearest_symbol_at_address() private runtime_loader
export to include imageName and exactMatch arguments.
The imageName holds the SONAME of the image, if available, so cannot
neccessarily be extracted from the image path.
Whether or not there was an exact match, i.e. the symbol with its size
contains the address, is now returned in exactMatch.
When enabled (using heap_debug_dump_allocations_on_exit(true) or
MALLOC_DEBUG=e) this causes a dump of all remaining allocations when
libroot_debug is unloaded. It uses terminate_after to be called as
late as possible.
When combined with alloc stack traces this makes for a nice if a bit
crude leak checker. Note that a lot of allocations usually remain
even at that stage due to statically, lazyly and globally allocated
stuff from the various system libraries where it isn't necessarily
worth the overhead to free them when the program terminates anyway.
When configured to do so (using heap_debug_set_stack_trace_depth(depth)
or MALLOC_DEBUG=s<depth>) the guarded heap now captures stack traces on
alloc and free.
A crash due to hitting a guard page or an already freed page now dumps
these stack traces. In the case of use-after-free one can therefore see
both where the allocation was done and where it was freed.
Note that there is a hardcoded maximum stack trace depth of 50 and that
the alloc stack trace takes away space from the free stack trace which
uses up the rest of that maximum.
The get_stack_trace syscall generates a stack trace using the kernel
debugging facilities and copies the resulting return address array to
the preallocated buffer from userland. It is only possible to get a
stack trace of the current thread.
The lookup_symbol syscall can be used to look up the symbol and image
name corresponding to an address. It can be used to resolve symbols
from a stack trace generated by the get_stack_trace syscall. Only
symbols of the current team can be looked up. Note that this uses
the symbol lookup of the kernel debugger which does not support lookup
of all symbols (static functions are missing for example).
This is meant to be used in situations where more elaborate stack trace
generation, like done in the userland debugging helpers, is not possible
due to constraints.
* Add a BRow default constructor that use font size to compute height.
* Min height size for Title and Row are decoupled.
* The font ratio for Title and Row are decoupled.
* For small font use min height (set to usual 16.0).
* Better baseline formula.
* Fixes#11944.
This allows for something similar as was implemented in 217f090 but
makes it optional and configurable.
The MALLOC_DEBUG environment variable now can take "a<size>" to set
the default alignment to the specified size. Note that not all
alignments may be supported depending on the heap implementation.
* So that you know how much already was, and still has to be downloaded.
* Automatic whitespace cleanup.
* The link in FetchFileJob.h did not fetch the correct header under
Haiku anymore (since the addition of the private headers to the
image).
* drop my fdt tests
* we have to call fdt parsing code *after* cpu_init (why?)
* pass fdt pointer to all FDT support calls to avoid confusion
once we get into the kernel land
* look for PL011 compatible uart and use it
* Add some saftey checks to serial putc code to avoid null*
* fdt_node_check_compatible returns 0 on success not 1
* fdt_get_device_reg needs to add the SOC base to the result
* fdt_get_device_reg might need to add the second range cell
instead of reg?
* And call it from the DNS client -- this is the only add-on that does
not trigger a configuration or settings update, so we have to notify
the changes manually.
* Get{Interface|Network|Service}() methods are now const.
* Added variants of Interface(), and Service() that are const.
* Added new BNetworkServiceSettings::IsRunning() convenience method that
reflects the status quo rather than the settings.
