1) A session request gets denied if there is no matching session policy.
(The <defaul-policy/> tag can be used for the former default behavior)
2) A session request gets denied if the MAC address is given through the
matching policy but this address cannot be allocated.
3) A session request gets denied if the MAC address is not given through the
matching policy and it is also not possible to allocate one.
Issue #3040
This patch adjusts the implementation of the base library and core such
that the code no longer relies on deprecated APIs except for very few
cases, mainly to keep those deprecated APIs in tact for now.
The most prominent changes are:
- Removing the use of base/printf.h
- Removing of the log backend for printf. The 'Console' with the
format-string parser is still there along with 'snprintf.h' because
the latter is still used at a few places, most prominently the
'Connection' classes.
- Removing the notion of a RAM session, which does not exist in
Genode anymore. Still the types were preserved (by typedefs to
PD session) to keep up compatibility. But this transition should
come to an end now.
- Slight rennovation of core's tracing service, e.g., the use of an
Attached_dataspace as the Argument_buffer.
- Reducing the reliance on global accessors like deprecated_env() or
core_env(). Still there is a longish way to go to eliminate all such
calls. A useful pattern (or at least a stop-gap solution) is to
pass the 'Env' to the individual compilation units via init functions.
- Avoiding the use of the old 'Child_policy::resolve_session_request'
interface that returned a 'Service' instead of a 'Route'.
Issue #1987
The minimal-footprint Ada runtime for implementing library-like
functionality in SPARK is now called "spark" runtime.
The full Ada runtime for entire components written in Ada and using the
libc as glue to the underlying system will move to the world repository
as "ada" runtime.
Issue #3144
Also added a report_rom for USB devices and let the driver report like
in a real scenario. Can also be used for debugging by setting
verbose="yes" in report_rom.
The former 'Genode::Timed_semaphore' mechanism is moved to the private
part of the two remaining users, namely dde_rump and the libc. Note
there are now two private copies of 'timed_semaphore.h'. This should be
regarded as an interim step until the use of this mechanism is removed
from both users.
This patch also cleans up the mechanism from legacy Genode API calls and
global side effects (alarm-thread singleton). The test/timed_semaphore
is now located at the libports repository as it now tests a mechanism of
the libc. The former timed_semaphore library is no more.
Fixes#3121
Store all files generated by moc and rcc in the application's build
directory to prevent the use of unfinished generated files for other
applications built at the same time.
Issue #3115
Since the timer and timeout handling is part of the base library (the
dynamic linker), it belongs to the base repository.
Besides moving the timer and its related infrastructure (alarm, timeout
libs, tests) to the base repository, this patch also moves the timer
from the 'drivers' subdirectory directly to 'src' and disamibuates the
timer's build locations for the various kernels. Otherwise the different
timer implementations could interfere with each other when using one
build directory with multiple kernels.
Note that this patch changes the include paths for the former os/timer,
os/alarm.h, os/duration.h, and os/timed_semaphore.h to base/.
Issue #3101
Our overall nightly test time greatly decreases when the timeouts for
the single tests are not that over-pessimistic. Using the slowest
platforms as reference, this commit reduces the test timeouts.
Ref #3027
Call 'tcp_output' if application data has been successfully queued. This
sends data immediately that may otherwise remain queued until the next
periodic TCP timer event.
This reverts a change made in 3e31e2ba53.
Fix#3067
FreeBSD implements 'clock' with an accuracy of 128 ticks-per-second for
compatibility reasons, Linux uses 1000000 per-second. Remove 'clock' and
print an error because it is unlikely that this is the resolution
expected by the application.
Fix#3057
Return a value in the same width as provided by the caller of sysctl for
PHYSMEM and USERMEM. This is to ensure that if a caller provides a
64-bit integer, a 64-bit value will be returned for 32-bit machines.
issue #3060
This enables Qt5 applications to set a Genode label via 'setWindowTitle'
from within Qt5 applications, and thus, making them identifiable to
other Genode components, like a layout manager.
fixes#3046
Move the libc-i386, libc-amd64, and libc-arm include directories into
the standard "include/spec" directory. This allows the platform specific
headers in the libc API package to be detected in a generic manner.
Ref #3051
The pthread API is considered a standard feature of libc so better to
simply merge it with the libc. Pthreads are in fact already a part of
the libc in the form of weak symbols. This merger is also a prerequisite
for better integrating pthreads with the libc I/O task.
Fix#3054
The PDF viewer can crash under a number of conditions due to changes to
the internal framebuffer model that were made to support mouse wheel
panning. These changes are reverted until the model can be reimplemented
to explicitly support page panning.
Fix#3021
This commit replaces the former floating_window_layouter with a new
window_layouter component that supports the subdivision of screen space
into columns and rows, the concept of layers, and the principle ability
to store window layout information across reboots. The latter is
accomplished by reflecting the component's internal state as a 'rules'
report to the outside.
Fixes#3031
For being able to build the tests via source archives, the 'base'
library must be denoted as dependency explicitely in their 'target.mk' file.
This is because when building archives, the API dependencies of used APIs are
not taken into account.
Use the Timer session duration for CLOCK_MONOTONIC and CLOCK_UPTIME.
Use the Genode::Duration object for passing internal time, it supports
sub-millisecond time and helps disambiguate units of time.
Fix#3018
Block and loop until application writes are sent or buffered in their
entirety. Do not call "tcp_output" directly, LwIP calls this procedure
internally and calling it again appears to disrupt the LwIP TCP state
machine.
Fix#3017
