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....)
QFontMetrics::leading() was zero for Consolas on Windows in Qt5, but is
nonzero in Qt6. This revealed that we were inconsistently using height()
and leading() to calculate our line height. Just use lineSpacing()
instead.
Fixes#18438.
This change adds computed values for reports, sequence analysis between
segments, conversation and endpoint taps, and a new statistics menu
and dialog.
MS-DOS Date and MS-DOS Time are packed 16-bit values
(https://learn.microsoft.com/en-us/windows/win32/sysinfo/ms-dos-date-and-time)
and when combined they make a 32-bit value.
In the original minizip that comes with zlib, the combined dosDate
parameter is a uLong, which is 64 bits on LP64 platforms. In minizip-ng,
it is a uint32_t.
At one point, minizip-ng renamed the dosDate struct member of
zip_fileinfo to dos_date, but more recent versions changed it back
to dosDate for compatibility, except the size remains different,
so our compatibility check can't distinguish the size.
clang (and possibly other compilers) complain about shortening a 64 bit
unsigned long to a uint32_t so make the return value from our
qDateToDosDate a uint32_t as it should be to avoid warnings on
distributions with minizip-ng
Also the maximum year value that can be stored in the format is
127, since it occupies bits 9-15 of the MS-DOS Date. (There was
probably some confusion since the maximum year is 2107, but its
offset from 1980, not 1900.)
As the Qt6 QString::QString(const QByteArray &ba) documenation says:
"Note: any null ('\0') bytes in the byte array will be included in this
string, converted to Unicode null characters (U+0000). This behavior is
different from Qt 5.x."
Make sure FieldInformation::toString() truncates its display label byte
array before converting it to a QString.
Fixes#18428
This removes the last dependency of the logging subsystem on the
preferences module. The latter is started much later than the former
and this is an issue.
The Windows-only preference "gui.console_open" is stored in the
registry as HKEY_LOCAL_USER\Software\Wireshark\ConsoleOpen. The semantics
are exactly the same. The preference is read by the logging subsystem
for initialization and then again by the preferences (read/write) so
the user can configure it as before.
The code to store the preference also in the preferences file was
kept, for backward compatibility and because it is not incompatible
with using the Registry concurrently.
The elimination of the prefs dependency also allows moving the Windows
console logic to wsutil and add the functionality to wslog directly,
thereby eliminating the superfluous Wireshark/Logray custom log handler.
To be able to read the ws_log_console_open global variable from
libwireshark it becomes necessary to add a new export macro
symbol called WSUTIL_EXPORT.
This adds a new attribute that allows declaring Wireshark
functions as deprecated.
Also disabe -Werror with deprecated declarations Deprecated
declarations can be introduced suddenly with a new version
of an external dependency or a new internal deprecation and
that has its own timeline to fix. We should still be able to
build with -Werror in that case.
There are many screens with a display filter edit box but they should
not wallop the status line on the main window. Display syntax errors
on the local window in "hints" area.
Only update Status Line message when editing a display filter in the
Filter toolbar or Find Packet toolbar.
All source files should have COMPILE_FLAGS applied, not just
ui/qt/*.cpp.
This fixes setting -Werror on the Qt build, since that is
the only custom C++ compilation flag we are using at the moment.
Use size() instead, which is exactly the same as count(), and
is not deprecated. Seems to exist in all out supported Qt
versions, as far as I can tell.

Calls to setData are wrapped with beginResetModel/endResetModel
so don't call emit dataChanged() (per Qt suggestion)
Fixes "As the loop is worked, the size of the parents shrinks
with each item processed."
Set a minimum width for the stream and substream number spinboxes in the
"Follow" and "TCP Stream Graphs" dialogs. This provides a larger click
target and should make editing easier.
Fixes#18265.
Change anything that matches
grep -Eir '(signal|slot) *\( *on_action' ui
to new-style connections so that we can catch any future direct
connection conversion issues at compile time.
Change a connection from on_actionCaptureOptions_triggered to
showCaptureOptionsDialog and make showCaptureOptionsDialog public. Fixes
an issue introduced in fcdb77dc.
Some older dissectors that predate Unicode and parse text protocols
are prone to generate invalid UTF-8 strings. This is a bug and can have
safety implications.
For example passing invalid UTF-8 to proto_tree_add_string() is a
common bug. There are safeguards in format_text() but this should
not be relied on as a general solution to the problem.
For one, as the name implies, it is only used with representation of a
field value, which is not the same as the value itself of an FT_STRING field.
Issue #18317 shows another reason why.
For now this compile flag only enables extra checks for string ftypes,
which covers a subset of proto.h APIs including
proto_tree_append_string(). Later is should be extended to other
interfaces.
This is also not expected to be disabled for release builds because
there are still many dissectors that do not correctly handle strings.
More work is needed to 1) identify them and 2) fix them.
