The default constructor didn't initialize all members, some of them holding
pointers. In the de-constructor the _name pointer was tried to free up, even
when it was not initialized.
Avoid any hassle for uninitialized members and just initialize it. Fixes
sporadic page fault on x86_64 base-nova.
Issue #155
With this patch, the 'Signal_receiver::dissolve()' function does not return
as long as the signal context to be dissolved is still referenced by one
or more 'Signal' objects. This is supposed to delay the destruction of the
signal context while it is still in use.
Fixes#594.
With this change, init becomes able to respond to config changes by
restarting the scenario with the new config. To make this feature useful
in practice, init must not fail under any circumstances. Even on
conditions that were considered as fatal previously and led to the abort
of init (such as ambiguous names of the children or misconfiguration in
general), init must stay alive and responsive to config changes.
This patch improves the config handling by falling back to a static
string (empty "<config />") if no valid config ROM module could be
found. This can happen initially, but also at runtime when the ROM
module dissapears, e.g., a ROM module accessed via fs_rom where the
corresponding file gets unlinked.
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
When matching the 'label' session argument using '<if-args>' in a
routing table, we can omit the child name prefix because it is always
the same for all sessions originating from the child anyway. Therefore,
this patch adds a special case for matching session labels. It makes the
expression of label-specific routing more intuitive.
Add functionality to lookup an object and lock it. Additional the case is
handled that a object may be already in-destruction and the lookup will deny
returning the object.
The object_pool generalize the lookup and lock functionality of the rpc_server
and serve as base for following up patches to fix dangling pointer issues.
With this patch, the loader installs an optional client-provided fault
handler as default CPU exception handler and RM fault handler for all
CPU and RM sessions of the loaded subsystem. This way, loader clients
become able to respond to failures occuring within the subsystem.
The new feature is provided via the added 'Loader::fault_handler' RPC
function.
The 'run/failsafe' test covers two cases related to the loader, which
are faults produced by the immediate child of the loader and faults
produced by indirect children.
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 block count in DMA requests is limited to 8 bit. Therefore,
if a client requests more than 255 blocks in a single packet request,
split the request in a loop.
