Profile files which is only used in Qt is not automatically registered
during startup and must be explicit registered.
Add profile_register_persconffile() to handle this registration.
Besides the obvious limitation of being unavailable on Windows,
the standard is vague about getopt() and getopt_long() has many
non-portable pitfalls and buggy implementations, that increase
the maintainance cost a lot. Also the GNU libc code currently
in the tree is not suited for embedding and is unmaintainable.
Own maintainership for getopt_long() and use the musl implementation
everywhere. This way we don't need to worry if optreset is available,
or if the $OPERATING_SYSTEM version behaves in subtly different ways.
The API is under the Wireshark namespace to avoid conflicts with
system headers.
Side-note, the Mingw-w64 9.0 getopt_long() implementation is buggy
with opterr and known to crash. In my experience it's a headache to
use the embedded getopt implementation if the system provides one.
Save a list of all user options that were specified on the Wireshark
command line using the `-o` option. Reapply those preferences after
reloading Lua plugins. Fixes the behaviour given in #12331 wherein such
prefs were reset to the defaults, not the command-line values, when
reloading Lua plugins.
When the user changes a preference in the Wireshark UI, remove that
preference from the stored command line options, so it doesn't get reset
when Lua plugins are reloaded again.
Set PacketDiagram as parent of QGraphicsScene so the scene is destroyed
together with PacketDiagram.
Dynamically allocate WiresharkApplication and explicitly call its
destructor when no longer needed. This results in deletion of
FunnelAction objects created in register_menu_cb() and QAction objects
created in TapParameterDialog::registerDialog(). For some reason, when
breakpoint was set inside WiresharkApplication destructor it would not
get triggered on exit, and so the child objects would get reported as
memory leaks.
Delete main window and application only after epan_cleanup(). This makes
lua plugins actually call ops during cleanup (e.g. destroy_text_window)
and makes it possible to free the memory allocated in FunnelStatistics
constructor.
Don't store the comments in a capture_options structure, because that's
available only if we're being built with capture support, and
--capture-comment can be used in TShark when reading a capture file and
writing another capture file, with no live capture taking place.
This means we don't handle that option in capture_opts_add_opt(); handle
it in the programs that support it.
Support writing multiple comments in dumpcap when capturing.
These changes also fix builds without pcap, and makes --capture-comment
work in Wireshark when a capture is started from the command line with
-k.
Update the help messages to indicate that --capture-comment adds a
capture comment, it doesn't change any comment (much less "the" comment,
as there isn't necessarily a single comment).
Update the man pages:
- not to presume that only pcapng files support file comments (even if
that's true now, it might not be true in the future);
- to note that multiple instances of --capture-comment are supported,
and that multiple comments will be written, whether capturing or reading
one file and writing another;
- clarify that Wireshark doesn't *discard* SHB comments other than the
first one, even though it only displays the first one;
Version info is an aspect of UI implementation so move it to
a more appropriate place, such as ui/. This also helps declutter
the top-level.
A static library is appropriate to encapsulate the dependencies
as private and it is better supported by CMake than object libraries.
Also version_info.h should not be installed as a public header.
Instead of receiving the program name from GLib, pass it explicitly
to ws_log_init() instead and use that to initialize the GLib program
name.
ws_log_parse_args() will now exit the program when it encounters an
argument error if exit_failure >= 0.
A domain filter can be given in the environment variable
'WS_LOG_DOMAINS' or in a command-line options "--log-domains".
The filter is specified as a comma separated case insensitive list,
for example:
./tshark --log-domains=main,capture
Domain data type switches from an enum to a string. There is no
constaint on adding new domains, neither in code or at runtime.
The string format is arbitrary, only positive matches will produce
output.
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.
Initialize the exit status before the loop, and just break out of the
loop if something fails, so that the code following the loop can destroy
the console in Wireshark on Windows and then go to the clean exit code.
On Windows, rather than creating and destroying the console twice for
each interface, just create it when we start printing and destroy it
when we finish printing.
In dumpcap, if we're being run by TShark or Wireshark, if there are no
link-layer types, just provide an empty list to our caller; let them
construct an empty list of link-layer types when they read our output.
In the code that reads that list, don't report an error if the list is
empty, rely on the caller to do so.
Have capture_opts_print_if_capabilities() do more work, moving some
functions from its callers to it.
Replace the Wireshark code for that with code that matches what TShark
does.
Update a comment in TShark while we're at it.
Fixes#14215.
(Still leaves it popping up the full window, but that's a bigger
change.)
"Commonly-used" meaning "used by more than one source file".
Clean up the exit codes, combining some duplicates with different names,
and using some instead of raw numbers in some places.
The distinction between the different kinds of capture utility
may not warrant a special subfolfer for each, and sometimes the
distinction is not be clear or some functions could stradle
multiple "categories" (like capture_ifinfo.[ch]).
Simplify by having only a generic 'capture' subfolder. The
separate CMake libraries are kept as a way to reuse object code
efficiently.
Give details on what happens when running Wireshark from a GUI on
UN*Xes, or, at least, on {macOS,Ubuntu+GNOME,Ubuntu+KDE}, although
it's probably similar on other UN*Xes and on other desktop environments.
Have routines to report capture-file errors, using libwireshark error
codes and strings, that call through a pointer, so they can pop up
dialogs in GUI apps, print a message to the standard error on
command-line apps, and possibly do something different on server
programs.
Have init_report_message() take a pointer to structure containing those
function pointers, rather than the function pointers themselves, as
arguments.
Make other API changes to make that work.
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.
Have dumpcap in child mode return an error message with a primary and
secondary string, instead of using stderr. When writing to the console
log we ignore the second message to prevent flooding the log with
tutorial-like info on permissions.
Eliminate WTAP_FILE_TYPE_SUBTYPE_ERF and
WTAP_FILE_TYPE_SUBTYPE_SYSTEMD_JOURNAL - instead, fetch the values by
name, using wtap_name_to_file_type_subtype().
This requires that wtap_init() be called before epan_init(); that's
currently the case, but put in comments to indicate why it must continue
to be the case.
Increase the minimum required version of Qt from 5.3 to 5.6. The various
Linux distribution versions that shipped with earlier Qt versions (RHEL
6, Fedora 23, openSUSE 13.2, Debian jessie, Ubuntu 16.04) have either
reached end of support or will do so soon.
The official Qt 5.6 releases for macOS require 10.8, so make that the
minimum macOS version.
Remove a bunch of no-longer-needed version checks.
Pull the code to register plugin taps, and the loop to register built-in
taps, into a single register_all_tap_listeners() routine.
This leaves it up to libwireshark, not to the programs using it, to know
how to register them.
We can't determine the version number, as there's nothing in the header
to indicate the version with which we were compiled, nor is there an API
to determine the version with which we're running.
Make sure NSView.wantsLayer is true by setting QT_MAC_WANTS_LAYER=1 at
startup if we're running on Big Sur and we were built with a version of
Qt susceptible to QTBUG-87014. Fixes#17075?
Start the limit at 2^32-1, as we use a guint32 to store the frame
number.
With Qt prior to Qt 6, lower the limit to 53 million packets; this
should fix issue #16908.
This reverts commit 5df2925434.
The problem only showed up in tfshark.c, and was caused by tfshark.c
using stuff from ui/urls.h but not *including* ui/urls.h.
If you use it, GCC 9.3.0 seems to think there's a missing parenthesis
somewhere, just as the version of clang++ in my version of Xcode does,
even though other versions of GCC don't. I'm clearly missing something
obscure about C here; I give up.
Add ui/urls.h to define some URLs on various of our websites. Use the
GitLab URL for the wiki. Add a macro to generate wiki URLs.
Update wiki URLs in comments etc.
Use the #defined URL for the docs page in
WelcomePage::on_helpLabel_clicked; that removes the last user of
topic_online_url(), so get rid of it and swallow it up into
topic_action_url().
Remove the --check-addtext and --build flags. They were used for
checkAddTextCalls, which was removed in e2735ecfdd.
Add the sources in ui/qt except for qcustomplot.{cpp,h}. Fix issues in
main.cpp, rtp_audio_stream.cpp, and wireshark_zip_helper.cpp.
Rename "index"es in packet-usb-hid.c.
We aren't using them now; stick to libpcap APIs (including Windows-only
libpcap APIs).

In each of our executables we were calling "setlocale(LC_ALL, "")" at
startup. This told Windows that output was encoded using the current
system code page. Unless the code page was 65001 (UTF-8), this was a lie.
We write UTF-8 to stdout and stderr, so call "setlocale(LC_ALL, ".UTF-8)"
at startup on Windows. This lets the CRT translate our output correctly
in more cases.
Clarify and expand the OUTPUT section in the tshark man page.

We handle Qt and GLib logging in the same handler, which means that if
we map qDebug messages to G_LOG_LEVEL_DEBUG they won't be printed by
default. This can make debugging the UI more confusing, since sprinkling
in qDebug()s is a common Qt debugging method. If you're focused on
fixing a bug it's easy to forget that you need to use qWarning() or
change the logging level preference instead.
Set the log level for qDebug messages to G_LOG_LEVEL_WARNING so that
they show up.
