This patch introduces keyboard-focus events to the 'Input::Event' class
and changes the name 'Input::Event::keycode' to 'code'. The 'code'
represents the key code for PRESS/RELEASE events, and the focus state
for FOCUS events (0 - unfocused, 1 - focused).
Furthermore, nitpicker has been adapted to deliver FOCUS events to its
clients.
Fixes#609
This patch extends the file-system interface with the ability to monitor
changes of files or directories. The new 'File_system::sigh' function
can be used to install a signal handler for an open node.
The 'ram_fs' server has been enhanced to support the new interface. So
any file or directory changes can now be observed by 'ram_fs' clients.
Fixes#607
Several users of the signal API used custom convenience classes to
invoke signal-handling functions on the reception of incoming signals.
The 'Signal_dispatcher' pattern turned out to be particularly useful. To
avoid the duplication of this code across the code base, this patch
adds the interface to 'base/signal.h'.
Furthermore, the patch changes the 'Signal::num()' return type from int
to unsigned because negative numbers are meaningless here.
Fixes#511
This patch reflects eventual allocation errors in a more specific way to
the caller of 'alloc_aligned', in particular out-of-metadata and
out-of-memory are considered as different conditions.
Related to issue #526.
The eglgears application depends on 'sqrt'. With the old tool chain,
this symbol was resolved through the dependencies of the 'gallium'
library. This does not work anymore for the new tool chain.
A similar issue arised for avplay, where we need to explicitly
state the av components in the LIBS declaration of the target.
GCC warns about uninitialized local variables in cases where no
initialization is needed, in particular in the overloads of the
'Capability::call()' function. Prior this patch, we dealt with those
warnings by using an (unreliable) GCC pragma or by disabling the
particular warning altogether (which is a bad idea). This patch removes
the superfluous warnings by telling the compiler that the variable in
question is volatile.
Make sure unlock is called when 'global_mutex' reaches zero count. Add verbose
variable in order to disable some output. Disable irritating 'Overflow' messages
in 'sys_mbox_post' and 'sys_mbox_try_post' per default. This may happen and is
not an error, since the ring buffer is full and will be emptied eventually.
Remove priority from genode_org run script.
Should fix#347
Use slab allocators for small object sizes, do it the usual way otherwise.
This patch is related to #363. Using this optimization may be a viable
alternative to switching to the FreeBSD's malloc implementation.
Use 'Nic::Packet_allocator', wait for acknowledgements if packet allocation
fails. Updated 'lwip.run' and 'genode_org.run' to support OMAP4 correctly. Use
memcpy to copy PBUFs
May resolve issue #347
The recently added 'Genode::Path' class makes it easy to create absolute
paths. With this patch the 'ffat_fs' server uses the 'Genode::Path' class
where possible instead of working with 'f_chdir()' and relative paths.
This also solves the problem reported in issue #355, which was caused by
storing a relative file name in the 'File' node.
Fixes#355.
With this patch, when a 'Packet_alloc_failed' exception occurs in the
'write()' function, the function waits for a packet acknowledgement and
the release of the packet and then tries the packet allocation again.
Fixes#348.
This patch adds libstdc++ to libports. With the previous version of the
stdcxx library, the build system used the C++ standard library that
comes with the compiler. This mechanism was prone to inconsistencies of
types defined in the header files used at compile time of the tool chain
and the types provided by our libc. By building the C++ standard library
as part of the Genode build process, such inconsistencies cannot happen
anymore.
Note that the patch changes the meaning of the 'stdcxx' library for
users that happened to rely on 'stdcxx' for hybrid Linux/Genode
applications. For such uses, the original mechanism is still available,
in the renamed form of 'toolchain_stdcxx'.
The old values were much too small and the current ones are probably to
large but the TCP send throuhgput has increased noticeable (a few MiB/s
on the Pandaboard).
Fixes#343.
The 'fd_set' size calculation in the current version of the 'poll()'
function results in an amount which is smaller than the size of the
'fd_set' data type. With this patch the file descriptor sets get
allocated as plain stack variables.
Fixes#335.
This patch implements a service which provides the contents of a tar
archive via the 'File_system::Session' interface.
Configuration:
<config>
<archive name="tar_archive.tar" />
<policy label="label_of_client" root="/rootdir/for/client" />
</config>
Fixes#333.
Removes getpwent.c from build because the passwd facilities provided by
the FreeBSD libc will not be used anyway and add stub functions instead.
Now services which need these functions have to implement their own
(e.g. libc_noux).
Apparently, GNU make 3.81 picks the generic '%.h' rule instead of the
more specific 'rpc/%.h' rule during the preparation of the libc.
Changing the order of the rules solves the problem.
libc_resolv is a {free,get}addrinfo() plugin, mainly for use with NOUX.
We prefix the original libc functions to with 'libc_' so there is no
symbol conflict with file_operations.cc.
