This patch changes the 'depot_deploy' tool to spawn any number of
runtimes. In contrast to the original version, which merely consumed a
blueprint generated by a pre-configured 'depot_query' instance, the new
version actively generates queries as needed. So there is a feedback
loop between 'depot_deploy' and 'depot_query'. The instantiation of
subsystems is controlled by the '<start>' nodes of the 'depot_deploy'
configuration. For each start node, the tool tries to determine the
ingredients (provided by the depot) by asking the 'depot_query' tool.
Once the information is complete, a corresponding start node of the
dynamic init instance is generated.
This patch introduces the subnodes <provides>, <requires>, and
<content> to the <runtime> node. All <rom> sessions that are
expected from the depot appear within the <content> node, which
sets them nicely apart from <rom> sessions that may be required
as runtime arguments.
Note that the <requires> and <provides> nodes do not appear in the
patch because the existing depot_deploy tool does not interpret this
information (the pkg/test-fs_report runtime does not provide any
service, and the timer session is provided as a common route).
This patch adds the config attribute 'query'. If set to the value "rom",
the query information is obtained from a ROM session labeled "query".
Otherwise, the query information is expected to be part of the config.
This enables us to use the component in two different scenarios. In
one scenario, 'depot_query' is embedded in a managed dynamic init.
Here, taking the query from the config is easy. In the other scenario,
'depot_query' is running as a daemon with a once-configured VFS but
varying queries. The queries originate from a component that does not
control the 'depot_query' config.
The new 'Terminal_session::size_changed_sigh' RPC function registers a
signal handler that is triggered each time when the terminal size
changes. It enables the client to adjust itself to the new size by
subsequently calling the 'size' RPC function. Of all terminal servers,
only the graphical terminal triggers this signal.
- handle line wraps in 'ech()'
- take (1,1) origin into account in 'hpa()' and 'vpa()'
- unify handling of SGR escape sequences of different lengths
- accept the '[?2004h' and '[?2004l' escape sequences (used by midnight commander)
Fixes#2671
The 'Expanding_reporter' wrapper for the 'Reporter' eliminates
the burden of handling 'Xml_generator::Buffer_exceeded' exceptions
from components that generate reports.
Fixes#2655
Instead of having a lot of platform specific quirks in the run test,
and to also test it on platforms currently missing a NIC driver,
this commit removes hardware drivers from the nic_router and
nic_bridge run scripts, and uses the nic_loopback server instead.
AVL trees can't be copied with the default copy constructor as the
parent pointer of the first item of both of the resulting trees would
point to the original tree. Copying an AVL node, however, generally
violates the integrity of the corresponding tree. The copy constructor
of Avl_tree is used in some places but in those places it can be
replaced easily. So, this commit deletes the copy constructor of
Avl_node_base which makes Avl_node and Avl_tree non-copyable.
Issue #2654
On platforms without nic or audio driver support, the corresponding
functions to return the correct names should return a meaningful
name instead of an empty list. Otherwise, in an erroneous run-script
that calls those functions to append names to the boot modules
the whole 'bin' directory is appended instead, which leads to big
image files or errors when linking the boot modules to core.
This patch adds hooks for customizing the location of the configure
script within the package, the build target, as well as the install
step. This is useful for packages like tcl that deviate from the
usual layout of source packages.
Issue #2648
The 'trace_logger' component can be used to easily gather, process and export
different types of tracing data. Which subjects to select is configurable via
session label policies and thread names. Which data to collect from the
selected subjects can be configured for each subject individually, for groups
of subjects, or for all subjects. The gathered data can be exported as log
output.
This is an example configuration of the 'trace_logger' component which shows
the default value for each attribute except the policy.thread and
policy.label:
! <config verbose="no"
! session_ram="10M"
! session_arg_buffer="4K"
! session_parent_levels="0"
! period_sec="5"
! activity="no"
! affinity="no"
! default_policy="null"
! default_buffer="4K">
!
! <policy label="init -> timer" />
! <policy label_suffix=" -> ram_fs" />
! <policy label_prefix="init -> encryption -> "
! thread="worker"
! buffer="4K"
! policy="null" />
! </config>

Building this policy was disabled by a REQUIRES = riscv_toolchain_bugfix
to prevent compiler crashes on nightly test builds. Since the latest
RISCV toolchain update, test builds for RISCV crash at much more places
which makes this single work-around senseless.
Issue #2654
Previously, base/trace/buffer.h included base/thread.h which includes
base/trace/logger.h which includes base/trace/buffer.h.
Removed the base/thread.h include in base/trace/buffer.h as it is not
needed.
Issue #2654
The 'Buffered_xml' utility is used by three components and a fourth is
on the way. To avoid another duplication of the code, this patch makes
it publicly available at 'os/buffered_xml.h'.
This patch replaces the 'Heap' by a 'Sliced_heap' to avoid the
allocation of a 16 KiB memory block when 'dummy' acts as a server. On
seL4, such an allocation would exceed the 1M quota as assigned by the
init.run script.
The 'initial_width' and 'initial_height' attributes were added to
accomodate the use-case to set the initial dimensions whenever 'nit_fb'
is used in a dynamic fashion, e.g, in combination with a window manager.
These attributes may not be mixed with the 'width' and 'height'
attributes, which are mostly used when a static size configuration is
desired.
When a NIC session is destructed at the router, we have to remove all ARP
cache entries that match the MAC address of that session. Otherwise the
outdated entries might be re-applied later, leading to wrong destination
MAC addresses in routed packets.
Fixes#2637
