This patch refines the hover handling such that a float widget never
responds to hovering unless a child is hovered. This way, it becomes
possible to stack multiple float widgets within one frame and still
reach all child widgets.

Similarly to the way of how a <cursor> can be defined for a <label>
widget, a selection can be expressed as follows:
<label ...>
<selection at="2" length="12"/>
</label>

When setting the <dialog> attribute 'hover_details' to "yes", the hover
report features the character position of a hovered label.

This patch equips the label widget with the ability to display a text
cursor, as illustrated by the following example:
<label text="...">
<cursor at="10"/>
</label>

The value range supported by the 'Animated_rect' utility is constrained
to 2^11 by the used 32-bit integer type. The interpolation is performed
on fixpoint numbers with a fractional precision of 10 bits. The
non-linear interpolation as performed by the 'Lazy_value' utility
involves squaring the values. Hence, the interpolated integral values
must not exceed 2^11 (2*11 bits for the square plus 10 bit for the
fractional part require 32 bits). This range is too small for
high-resolution displays. Hence this patch replaces the 32-bit integer
type by a 64-bit integer type.
Fixes#3627
The wm used to remember the last pointer position when observing a leave
event. With such a stale pointer position, the wm would eventually
wrongly create an artifical motion event when a supposedly hovered
window changes its position (during an animated move). This can lead to
the propagation of the stale pointer position to the wm client, which,
in turn, may interpret the outdated position (e.g., the menu view would
report a wrong hover state).
This patch removes the stale state by resetting the '_pointer_pos' when
observing a leave event.
Fixes#3632
When specifying "/" or "" as rel_path to the 'Directory' constructor,
the constructed directory should refer to the same directory. The
implementation of the join utility did not consider this corner case. It
occurred during the attempt to use fs_query with "/" given as path.
This patch also adds a Directory::Entry::dir accessor that returns true
if the entry is a directory.
Fixes#3630
By writing out all dangling characters at destruction time, the
'Buffered_output' utility can be used as a local variable rather
than a long-living object.
Besides updating to a newer version the update adds the AC97 ICH driver
and addresses shortcomings with the OpenBSD emulation environment:
* Fix 'delay(9)' implementation - it now properly uses 'us' as unit,
which results on faster initialization of the drivers.
* Fix LOG output that got lost during commit f23579532 and bring over
the printf implementation from dde_linux for more structured
printing.
* As said the driver now recognizes the AUICH devices. So far it was
only tested with the device model in VirtualBox where it produces
stuttering audio, investigating the cause is still ongoing.
Fixes#3641.
- Remove dated 'Block::Driver' front end and implement
'Block::Request_stream' front end
- Remove all dynamic memory allocations but DMA memory allocations
- Remove 'Platform_hba' and implement platform specific functions in
'spec/<platform>/*'
- Ata and Atapi don't inherit from 'Port' any more, but are a member of
'Port' as a protocol implementation
- Use platform driver for MMIO mappings (x86)
- Exchange stateful initialization of Ata/Atapi with a sequential
initialization using 'wait_for_any' and 'retry' patterns
- Fix Atapi initialization by setting the byte count limit
- Set FIS receive base only when Cmd::FRE is disabled and Cmd::FR is 0
- Put everything in namespaces ('Ahci', 'Ata', or 'Atapi')
- Ata decides during read/write operations to use native-command queuing
or normal DMA requests
- Remove port claiming logic (is now done via 'Constructibles')
fixes#3636
The libc monitor facility enables the execution of monitor jobs by the
main thread when the monitor pool was charged. In comparison to the
current suspend/resume_all mechanism the main thread iterates over all
job functions in contrast to waking up all threads to check their
conditions by themselves. Threads are only woken up if the completion
condition was met.
This commit is the result of a collaboration with Christian Prochaska.
Many thanks for your support, Christian.
Fixes#3550
sleep(), usleep(), and nanosleep() now return immediately on
zero-timeout. Also, non-zero timeouts sleep at least 1 ms (the current
minimal timeout in libc), which compensates rounding errors.
Issue #3550
The ARP destination MAC was set to the Ethernet source MAC which is not
necessarily the MAC of the other ARP peer. Instead use the ARP source MAC of
the ARP request.
Instead of listening for new TCP/IP connections only,
the TCP terminal connects to a server when an IP address is
configured in the policy for a terminal client.
Fix#3619
If the suspend method for the main thread detects that the suspend
condition is false it must return the passed timeout value (not always
0). Otherwise, the caller may incorrectly assume the timeout expired.
Especially the initial reset ended up with an unusable keyboard in rare
cases before. This commit disables keyboard and mouse handling of i8042
during command sequences according to a note from
