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
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 3e31e2ba53ee25dcd8f9781e7b9f0a2c7c7be371.
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
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
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
The VFS LwIP plugin is page-faulting on connect error because the LwIP
library frees a failed TCP protocol control block before calling the
error callback, and then the VFS plugin dereferences the PCB to free it
a second time. This problem was caused by a failure to follow
documentation during a transition from a C callback to a C++ method.
Fix#2972
When 'notify_read_ready()' is called during 'select()' and fails,
suspending can cause a deadlock when the libc IO response handler becomes
active and calls 'select_notify()', which tries to acquire the
'select callback list lock', which is already acquired by the suspended
'select()' call.
It seems possible to ignore a failed 'notify_read_ready()' call instead of
suspending. When the VFS plugin calls the IO handler later when the
notification request can be processed, the 'select_notify()' call of the
libc IO response handler will eventually call 'notify_read_ready()' again.
Fixes#2970
Implement the passwd database subroutines with single-user database.
This database is populated with a <passwd/> sub-node of the libc
configuration node. All fields of the "passwd" struct may be specified
with reasonable defaults provided for a "root" user. This allows a
libc-based component to spoof user information for the sake of porting
existing Unix software.
A test is provided at run/libc_getpwent.
