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
* Account all RAM/CAP quota of a session except quota for metadata used in
core. The latter is considered when asking if a session can afford to make
an operation but it does not get accounted to always be able to pay back all
quota when a session closes. The general accounting mechanism is moved from
atop of the allocators down to the level of RAM/RM session operations.
* report statistics about session objects and quota if <report stats="yes"
quota="yes"/> is configured. (default is yes if <report> is present)
Issue #2953
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.
Fix#2919
GNU tar interprets the passed time value in local time by default, which
lead to unstable hashes again. So, now provide a complete date/time
value incl. time zone.
Related to #2842
There is a bug in the LwIP VFS plugin, the chained buffers used by Lwip
use sizes expressed in sixteen bits, and under conditions such as a read
of 1<<16 the higher bits are lost and the plugin performs a zero length
read, and the application interprets this as a closed connection.
