The deadlock reported in #3236 could be reproduced via the wm.run script
and the modification of test/nitpicker in commit "nitpicker: fix destroy
with invalid handle" by clicking on the testnit entry of the launchpad.
This patch fixes the deadlock by releasing the locked pointer early in
the destruction path, which is legitimate as the wm is single-threaded.
Fixes#3236
This patch adds the missing invalidation of the _hovered pointer to
User_state::forget, which is required to cover the situation where the
owner of the hovered view vanishes.
Fixes#4011
Improve consistency with the other base repositories, in particular
- Indentation of class initializers
- Vertical whitespace around control-flow statements
- Preferably place control-flow statements (return, break, continue) at
beginning of a line
- Placing the opening brace of a namespace at the end of line
- Placing the opening brace of a class at a new line
- Removing superfluous braces around single statements
- Two empty lines between methods/functions in implementation files
This patch simplifies the use of ccache with the build system. Up until
now, each developer had to set up the ccache hooks manually, adjust the
PATH variable, and customize the etc/tools.conf in each build directory.
With the patch, ccache can be enabled by un-commenting a single line in
the etc/build.conf file.
Fixes#4004
The Usb session allows for submitting packets even when the interface
in question is not yet enabled. Enabling an interface will configure
the udev members properly and is normally done implicitly during
processing of an 'ALT_SETTING' packet.
In case the interface was not enabled this leads to a page-fault in
the USB host-controller driver as 'ep' is NULL.
Fixes#3999.
This patch moves the bootstrap-link-address information from the
tool/run/boot_dir/hw file to board-specific property files that can be
accessed by using the board as key. This eliminates the need to
customize boot_dir/hw when hosting board-support in an external
repository.
Fixes#3998
The Vmm::Gic::Gicd_banked::Redistributor is used with Constructible, but
does not have a virtual destructor even though it has virtual methods.
This prompts clang to issue the following warning:
reconstructible.h:122:4: warning: destructor called on non-final
'Vmm::Gic::Gicd_banked::Redistributor' that has virtual functions
but non-virtual destructor [-Wdelete-non-abstract-non-virtual-dtor]
Fix this by inheriting Genode::Interface.
Issue #3984
Even though the binary patching of ldso must be performed only once,
this postprocessing step was executed on each run because the
postprocess.tag rule is phony (the tag file is never created).
This patch removes this phony behavior by creating the tag file.
Issue #3974
The _crt0_start_stack label points to a memory location containing the
size of the bootstrap stack. On AArch64 this should be an 8 byte value,
but the code only only defines half of those using asm .long statement.
The other half is expected to be 0, which is true when using GNU as.
This is not the case when using clang's integrated as however. Since
_crt0_stack_size is defined inside .text section clang uses 0xd503201f
value (aarch64 nop instruction) to fill the extra 4 bytes.
Fix this minor incompatibility by explicitly defining both halfs of
this 8 byte quantity.
Fixes#3987
The _dispatch_pending_io_signals and _original_suspended_callback member
variables are not used anywhere in the code. This prompts clang to produce
a warning message about it. Remove both variables to fix it.
Issue #3985
The "unsigned Nitpicker::Gui_session::layer()" function returns
~0UL. This prompts clang to produce a warning about implicit unsigned
long to unsigned int conversion. Fix it by returning ~0U instead of
~0UL.
Issue #3985
GCC doesn't care, but clang complains if [[fallthrough]] is not followed
by a semicolon. Existing Genode code is also not consitent in this regard.
This patch adds the extra semicolons since it works in both GCC and
clang.
Issue #3985
No code in this class uses this private member variable. This prompts
clang to produce a warning message about it. Fix it by dropping the
variable.
Issue #3985
The class has final destructor, but is not itself final. This prompts
clang to produce the following warning message:
class with destructor marked 'final' cannot be inherited from [-Wfinal-dtor-non-final-class]
~Vfs_plugin() final { }
^
vfs_plugin.h:39:13: note: mark 'Libc::Vfs_plugin' as 'final' to silence this warning
Issue #3985
This static inline function is not used anywhere. GCC does not care,
but clang warns about this. Remove the function to allow the code to
compile cleanly with both clang and GCC.
Issue #3985
