The C language does not guarantee that "char" is signed or unsigned; it
just states that it's "implementation-dependent".
At least some C compilers for some architectures make it unsigned, so
you need "signed char" to get a signed value. In particular, it's
unsigned for most ARM compilers (compilers for Darwin-based OSes such as
macOS make it signed on all platforms, including ARM), which causes a
warning about "ba[i] < '\0'" always being false.
The purpose of that test is to check for octets that correspond neither
to ASCII printable characters nor ASCII control characters; just test
with !g_ascii_isprint(ba[i]) && !g_ascii_iscntrl(ba[i]). (Those are
macros, so it's not as if that adds any subroutine call overhead.)
Add some comments to explain what's being done in
ShowPacketBytesDialog::symbolizeBuffer() while we're at it. (Not one of
the better uses of C++ polymorphism, giving "replace the octet at this
location with this sequence of octets" and "replace all octets equal to
this value with this sequence of octets" the same name, even though what
they do differs significantly. I would have called one replace_at and
the other replace_all or something such as that, but the Qt developers
didn't ask me....)
Add Percent-encoding to the list of encoding types that Show
Packet Bytes can handle.
There's a function added to glib 2.66 to handle this for arbitrary
bytes that might have internal nulls (and which allows the result
to be non UTF-8), but we don't require that version yet, so extend
the existing function.
Related to #1084
There is no need for nesting event loops when showing menus. Show menus
asynchronously to limit possibilities of hard to debug problems related
to re-entering event loop.
The Qt implicit casts from QByteArray to QString all use
size = -1, meaning to the end of the string.
This causes gcc 12.1 with -O2 to produce a very dubious stringop-overread
warning, by computing both sides of a branch even when it shouldn't:
/usr/include/qt5/QtCore/qstring.h:706:69: error: ‘size_t strlen(const char*)’ reading 1 or more bytes from a region of size 0 [-Werror=stringop-overread]
706 | return fromUtf8_helper(str, (str && size == -1) ? int(strlen(str)) : size);
| ~~~~~~^~~~~
There's also a similar error with QByteArray.constData(), even though
isEmpty() should return True when the QByteArray is NULL.
(Adding isNull() prevents the warning but is redundant.)
Use DIAG_OFF and DIAG_ON to ignore the warning on GCC 12.1 and higher.
Fix#18090.
Increase the minimum required version of Qt from 5.6 to the next
LTS version, 5.9. The various Linux distributions that have not
released an update to 5.9 or later (SLES 12, Debian stretch) are
nearing end of support, and can be supported by the Wireshark 3.6 LTS
release.
Qt 5.9 requires macOS 10.0, so make that the minimum macOS version
as well.
Remove unneeded version checks (except from QCustomPlot).
Rename the main_window class and UIC files to wireshark_main_window and
the MainWindow class to WiresharkMainWindow. Copy wireshark_main_window
/ WiresharkMainWindow to logwolf_main_window / LogwolfMainWindow.
Remove the Wireless menu from Logwolf.
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
will likely have to change many or most of them back, but that's a
commit for another time.
Qt 5.10 added qsizetype, aka an ssize_t and Qt 6 makes extensive use of
it. Add a compatibility typedef and use it where we can. Cast it away
where we can't.
Qt5 recommended to use QRegularExpression instead of QRegExp.
Qt6 deprecated QRegExp and provides it in Qt5 compatibility module.
QRegularExpression is generally faster and safer to use as the results
are returned in separate QRegularExpressionMatch instead of modifying
interal QRegExp object state.
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.
The patch reintroduces WiresharkDialog::captureFileClosed() method and
calls captureFileClosing() and captureFileClosed() in right order.
Both methods call updateWidgets() at its end.
All dialogs were reviewed and captureFileClosing/Closed methods updated
when appropriate.
captureEvent() method in multiple dialogs changed to captureFileClosing/Closed
as it does same actions - looks like old style of detecting of capture
file closing.
Run
$ gsed -i -e 's/\(tr *(.*".*\)" *UTF8_HORIZONTAL_ELLIPSIS/\1…"/' $( ag -l 'tr *\(.*" *UTF8_HORIZONTAL_ELLIPSIS' )
$ gsed -i -e 's/\(tr *( *\)UTF8_HORIZONTAL_ELLIPSIS *"/\1"…/' $( ag -l 'tr *\( *UTF8_HORIZONTAL_ELLIPSIS *"' )
in ui/qt. As discussed in #16812, the UTF8_ macros were required at one
time because we only allowed ASCII in our source code. However, that
requirement has since been relaxed and Qt's translation framework
doesn't handle concatenating strings and macros very well.
Use UTF8 middle dot for non-printable characters in ShowPacketBytes to
clearly show the difference between a non-printable character and '.',
and to align with the PacketBytes view.
Introduced QT 5.7 calls in my recent change (also C+11, which is

Use the QT text codec support to add charset conversions for all character
encodings supported by QT to Show Packet Bytes and Follow Stream (Save As
will convert to UTF-8.) Note that this is dynamic and the exact list will
depend on the version of QT and if libicu support is enabled. This does
make the list of codecs pretty long, so hopefully it shows up well on all
the different QT styles.
This does not yet support when multibyte characters span more than one packet
in Follow Stream, though the current code doesn't do that for UTF-8 or UTF-16
already. This is probably most useful for HTTP captures.
