Windows implements so called CRT handlers, which will catch any
assertions happening inside so called crt routines and either
displays a debug dialog (Cancel, Retry, Ignore) or outright crashes
the application.
See
https://docs.microsoft.com/en-us/cpp/c-runtime-library/parameter-validation?view=msvc-170
for an explanation of the behaviour.
Now, in the current situation here, close will detect (correctly)
that the pipe it is supposed to be closing is already closed. This
happens (again correctly) because it had been closed by the extcap
application.
The change added, checks for a closed pipe first, and if so just
returns -1 (as it should) silently without calling the CRT routine,
therefore not crashing
Move WiresharkApplication.{cpp,h} to MainApplication.{cpp,h}. Add back
WiresharkApplication as a thin superclass of MainApplication, similar to
LogsharkApplication. Change all of our wsApp references to mainApp. We

Pass the funnel operations ID to new_text_window and new_dialog so that

Ping #17590.
Experience has shown that:
1. The current logging methods are not very reliable or practical.
A logging bitmask makes little sense as the user-facing interface (who
would want debug but not crtical messages for example?); it's
computer-friendly and user-unfriendly. More importantly the console
log level preference is initialized too late in the startup process
to be used for the logging subsystem and that fact raises a number
of annoying and hard-to-fix usability issues.
2. Coding around G_MESSAGES_DEBUG to comply with our log level mask
and not clobber the user's settings or not create unexpected log misses
is unworkable and generally follows the principle of most surprise.
The fact that G_MESSAGES_DEBUG="all" can leak to other programs using
GLib is also annoying.
3. The non-structured GLib logging API is very opinionated and lacks
configurability beyond replacing the log handler.
4. Windows GUI has some special code to attach to a console,
but it would be nice to abstract away the rest under a single
interface.
5. Using this logger seems to be noticeably faster.
Deprecate the console log level preference and extend our API to
implement a log handler in wsutil/wslog.h to provide easy-to-use,
flexible and dependable logging during all execution phases.
Log levels have a hierarchy, from most verbose to least verbose
(debug to error). When a given level is set everything above that
is also enabled.
The log level can be set with an environment variable or a command
line option (parsed as soon as possible but still later than the
environment). The default log level is "message".
Dissector logging is not included because it is not clear what log
domain they should use. An explosion to thousands of domains is
not desirable and putting everything in a single domain is probably
too coarse and noisy. For now I think it makes sense to let them do
their own thing using g_log_default_handler() and continue using the
G_MESSAGES_DEBUG mechanism with specific domains for each individual
dissector.
In the future a mechanism may be added to selectively enable these
domains at runtime while trying to avoid the problems introduced
by G_MESSAGES_DEBUG.
Remove the editor modeline blocks from most of the source files in ui/qt
by running
perl -i -p0e 's{ \n+ /[ *\n]+ editor \s+ modelines .* shiftwidth= .* \*/ \s+ } {\n}gsix' $( ag -g '\.(cpp|h)' )
then cleaning up the remaining files by hand.
This *shouldn't* affect anyone since
- All of the source files in ui/qt use 4 space indentation, which
matches the default in our top-level .editorconfig
- The one notable editor that's likely to be used on these files and
*doesn't* support EditorConfig (Qt Creator) defaults to 4 space
indentation.
Use pushStatus() in C++ code, improve translation support and end
each message with a dot.

The _open_osfhandle() does take ownership of the handle and thus the
underlying handle gets closed at the same time as the file-descriptor.
As we want to preserve the underlying pipe handle, create a duplicate
handle and use the duplicate handle with _open_osfhandle().

When extcap fails before connecting to pipes, ws_write() in
InterfaceToolbar::controlSend() fails and error message is displayed to
the user.
Before this change, the message box would block until the user closes
the message. As the controlSend() was called inside "capture prepared"
context the remaining capture preparation code would wait for the user
action. However, the pipeTimeout() would get called before user confirms
the message as Qt would be processing all events in the main event
queue. This led to "capture failed" executing before "capture prepared"
finished. Such interruption caused multiple issues including freeing
buffer that was not yet allocated.
