* The log history of a test is stored as a whole for the lifetime of the test.
* Matching of the log history against log patterns is done correctly now
(previously, a pattern like "AAB" on an input like "AAAB" wouldn't have
triggered).
* Use memcmp, memcpy, memmove instead of the former character-wise operations.
* Sanitizing of log input and log patterns now works more generic through the
new Filter class for all replacements/removals.
* Sanitizing is done as soon as a string is available and remains for the
lifetime of the test.
* Sanitizing doesn't interfer with the matching algorithm.
* Decomposing into small clearly named functions.

Make sure timers run at the same priority as component threads, otherwise
no timer progress can be made. See 'rtTimeNanoTSInternalRef' (timesupref.h)
and 'rtTimerLRThread' (timerlr-generic.cpp).
This is a follow-up patch for "noux: don't update mtimes for read-only
files". It eliminates warning messages during Sculpt's prepare step when
'cp' tries to update the mtimes of the source files.
When copying config/managed/deploy to config/deploy, the latter may
temporarily result in an empty configuration. Such an intermediate
state should be ignored to keep the currently running scenario in tact
instead of restarting it.
This patch addresses a corner case where the nitpicker focus is not
solely defined by mouse clicks or (exclusively) by a window manager, but
by a policy component that takes mouse clicks and other policy (e.g.,
a lock screen) into account. It ensures that each click that follows a
focus change (however initiated) results in a new "clicked" report even
when the report looks the same. To allow the policy component to
uniquely distiguish subsequent reports, the report features a new
'version' attribute.
Fixes#3493
This is a follow-up patch for issue #1784 that solves two
inconsistencies.
- The Vfs::Timestamp::INVALID matches File_system::Timestamp::INVALID
- The Noux libc plugin tests for Timestamp::INVALID instead of a
positive value.
The patch fixes the mtime info as shown in directory listings in
Sculpt's inspect window.
This patch let the VFS server reflect the session policy via the
writeable bit in directory entries instead of merely forwarding the bit
from the respective VFS plugin. This way, all files originating from a
read-only file-system session automatically appear in directory listings
as read-only files.

'dlopen' causes the ldso to open ROM connections, right now we only
support single file names for these ROM not paths. Therefore, we extract
the file name from path within libc's 'dlopen'
fixes#3551
This is an intermediate fix to handle sends to sockets shut down by the
peer already. A final fix in the libc would add support for the
MSG_NOSIGNAL send flag, generate SIGPIPE, and return the expected EINTR.
Then this patch is no longer required.
This commit also drops the obsolete patch for missing
sysconf(_SC_NPROCESSORS_ONLN), which is now part of libc.
The VFS server as reworked in issue #3547 responds to such an attempt
with a failure as acknowledgement, triggering the client-side error
"Error: packet operation=2 failed" at noux.
This patch prevents the driver from translating Insufficient_ram_quota
and Insufficient_cap_quota exceptions to Service_denied exceptions at
session-creation time. This enables the client to respond to such a
condition by retrying the session creation with increased session quota.
Add a new plugin for creating pipes between pairs of VFS handles. It is
intended to replace the libc_pipe plugin, one of the last remaining libc
plugins.
In contrast to the libc_pipe plugin, this plugin defers cross-handle
notification until I/O signal handling rather than block and unblock
readers using a semaphore. This is a performance regression in the case
of multiple threads blocking on a pipe, but shall be an intermediate
mechanism pending renovations within the libc VFS and threading layers.
As a side effect, threads blocked on a pipe might not be resumed until
the main thread suspends and dispatches I/O signals.
The "test-libc_pipe" test has been adjusted to use the VFS pipe plugin
and tests both local pipes and pipes hosted remotely in the VFS server.

Fix#2303
This patch reworks the VFS server to become easier to understand.
- The packet-stream handling is hidden from the node types.
- Introduced the notion of a "job" as an abstraction from the raw packet
stream.
- The processing of requests is split into three phases:
(1) accepting new jobs,
(2) the execution of jobs, and
(3) the delivery of acknowledgements.
- There is no longer a global fifo of pending nodes. Instead, each
session has a fifo of "active" nodes, which are nodes that wait
for the completion of jobs.
- The Io_node type no longer uses virtual functions as hooks for
the derrived classes. Instead, it provides a number of utility
functions.
- The control flow of the 'Io_progress_handler' is now the same as
for the session-local packet-stream handler.
- Removed dependency from 'file_system/node.h', which is a relic
from the ram_fs.
While reworking the code, the following semantic changes were made
additionally.
- The handling of SEEK_TAIL no longer overwrites the file content at the
end of the file.
- Removed diagnostic message at session-creation time.
- Write loop for continuous files
Issue #3547
Issue #2303
This patch reduces the debug noise for the prominent case of executing
bash with coreutils. Without it, the forked process will always ask for
more RAM immediately when starting up.
This change allows for the conversion of directory entries in place
(i.e., in the VFS server) and anticipates the potential future merge of
both types into one.
Issue #3547
This patch improves the libc's write operation to iterate on partial
writes to continuous files until the original write count is reached.
The split of large write operations into small partial writes as
dictated by the VFS infrastructure (e.g., constained by I/O buffer
sizes) becomes invisible to the libc-using application.

Make sure that at least entry is present in the .dynamic section, so the
PT_DYNAMIC segment points to something valid in case there are no
dynamic symbols.
issue #3537
This patch adds the ability to call 'kill' with the own PID to trigger
the execution of the handler of the specified POSIX signal. This is used
by 'bash', e.g., when cancelling the input of a command via control-c.
Related to issue #3546
This patch equips the VFS terminal file system with the ability to
detect user interrupts in the incoming data stream, and propagate this
information via the new pseudo file '.terminal/interrupts'. Each time,
the user presses control-c in the terminal, the value stored in this
pseudo file is increased. Thereby, a VFS client can watch this file to
get notified about the occurrences of user interrupts.
Fixes#3546
The scratch buffer is now allocated from the heap and is shared
between the test as they are executed in a serial fashion. This
change saves memory as the test are constructed at start-up.
Fixes#3539.
This patch adds support for watch notifications for the
'Readonly_value_file_system', which is often used by VFS plugins to
implement pseudo files. It thereby enables VFS clients to respond to
VFS-plugin events (think of terminal resize) dynamically.
