Catch out of RAM and capability exceptions and return error values.
Abort opening a composite directory at Dir_file_system where an
opendir call on any child file-system returns an OUT_OF_RAM or
OUT_OF_CAPS error.
Ref #2642
The timestamp-based rules of make do not work well for the publish tool
because depot archives are often re-created with the same content but a
different modification time, in particular when creating archives via
'FORCE'. This way, those archives are re-published every time, which
becomes a time-consuming operation since all archives must be signed.
This patch filters the targets based on the content that is already
present in the public/ location. All existing archives are skipped.
This change enables the use of negative values for the 'initial_width'
and 'initial_height' attributes to specify values that are relative to
the screen size. This is consistent with the meaning of the 'width' and
'height' attributes.
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.
