Currently the autocompletion engine always suggests a protocol
field completion, even in places where it isn't syntactically
valid.
Fix that by compiling the preamble to the token under the cursor
and checking the returned error. If it is DF_ERROR_UNEXPECTED_END
that indicates a field or literal value was expected. Otherwise
a field replacement is not valid in this position.
Fixes#12811.
Return an struct containing error information. This simplifies
the interface to more easily provide richer diagnostics in the future.
Add an error code besides a human-readable error string to allow
checking programmatically for errors in a robust manner. Currently
there is only a generic error code, it is expected to increase
in the future.
Move error location information to the struct. Change callers and
implementation to use the new interface.

QCustomPlot's adaptive sampling decimates the data to be plotted based
on the screen resolution. Specifically, if many data points fit within
the same pixel on the X (key) axis, then QCustomPlot attempts to plot
only the min value, the max value, and a few values in-between to
maintain a good "density" on the Y (value) axis.
The density QCustomPlot wants is about one datapoint for every 4 pixels
covered by the value range of a single X (key) pixel. Unfortunately,
this calculation is flawed if all values also fit within a single pixel
on the Y (value) axis - so this change fixes that bug.

Starting with Qt 5.10 (our earliest supported version),
Qt has a qsizetype (alias of ssize_t) that functions
like size() and indexOf() return. On clang that does not
have the same size as an int, so cast it away in a number
of places.
Rename flex macros using parenthesis (mostly a style issue):
DIAG_OFF_FLEX -> DIAG_OFF_FLEX()
DIAG_ON_FLEX -> DIAG_ON_FLEX()
Use the same kind of construct with lemon generated code using
DIAG_OFF_LEMON() and DIAG_ON_LEMON(). Use %include and %code
directives to enforce the desired order with generated code
in the middle in between pragmas.
Fix a clang-specific pragma to use DIAG_OFF_CLANG().
DIAG_OFF(unreachable-code) -> DIAG_OFF_CLANG(unreachable-code).
Apparently GCC is ignoring the -Wunreachable flag, that's why
it did not trigger an unknown pragma warning. From [1}:
The -Wunreachable-code has been removed, because it was unstable: it
relied on the optimizer, and so different versions of gcc would warn
about different code. The compiler still accepts and ignores the
command line option so that existing Makefiles are not broken. In some
future release the option will be removed entirely. - Ian

On older Qt versions (5.12?) QVector needs to be included,
not just QObject. (It isn't needed on 5.15, possibly because
QVector is an alias for QList in newer Qt versions.)
When creating a ProtoNode, count the (non-hidden) children and put
them in a QVector. This saves time having to iterate through all
of a node's children (or the parent's children) each time the
model or view wants to get the row or index number. Create and
delete the needed ProtoNodes when the root node is changed, instead
of recreating them on demand from the proto_nodes (since they're no
longer a thin wrapper.)

Properly generate filter expressions for custom columns by
using proto_construct_match_selected_string on each value and
then joining them together later instead of trying to split
the column expression value.
This ensures that escaping is done properly for display filter
strings, that commas internal to field values are not confused
with commas between occurrences, that for multifield columns
we can distinguish which field each value matches, etc.
It's not entirely clear whether AND or OR logic is appropriate
for multiple occurrences; currently OR is used.
Bump glib requirement to 2.54 for g_ptr_array_find_with_equal_func
(this doesn't drop support for any major distribution that already
meets our other library requirements, like Qt.)
Fix#18001.
Gtk popped up a search box when typing in the tree view.
Most places in Qt, a Search: field was added to the dialog.
Looks possible to buffer keystrokes and do a string search in Qt.
Default value is 400ms (even on Windows). Average typing speed of
200 cpm = 300ms per character = too close to 400ms when searching
the protocol name in Preferences -> Protocols.
When the classic profile has been cloned, and it contains
coloring rules, that are no longer valid or their syntax is
wrong, the export of single profiles will fail.
The reason for that is still being investigated. It seems
there might be an issue with selecting the right coloringfilter
to be selected.
This change only fixes the coloringrules file and the
index is selected from the base model instead
Previously, Wireshark was sorting all packets in a capture,
regardless whether they were actually visible or not. If you
are working with large PCAPs & filters, this is a MASSIVE
performance drag. Therefore, this commit changes this
by only sorting the visible packets which boosts the
sorting performance in filtered views massively.
Generate filter expressions for columns with multiple occurrences
by using the membership operator (which is semantically OR).
It's not clear if this approach makes more sense than AND;
there's use cases for both.
Don't do this for multifield custom columns, since we don't know
which values were found by which field. That takes changing
the column logic in several places.
Ping #18001
When running the profiles dialog from the main status bar,
some objects appear to be not cleaned up properly with Qt 6.
This will circumvent this, by creating an object for the
dialog and cleaning it on closing.
Fixes#18525
The context menu falsely assigns the proxied index to the context menu
entries, therefore always selecting the wrong model index for the
resulting functions.

Qt5's QFont::fromString() isn't compatible with Qt6's QFont::toString().
If we were built with Qt5, don't try to process a font preference that
was created by Qt6.
