Add the ability to cancel sorting. Since we now parse user inputs
during the sort, test and set the capture file read lock. Try to
sort in PacketList::captureFileReadFinished, since now sorting during
thawing won't happen if it's in the middle of a rescan.
Fix#17640
In certain situations using __MINGW64__ is not correct.
We want to have the condition apply using MinGW-w64 but also
using MSYS2, which the __MINGW64__ condition alone does not
capture.
Add a HAVE_MSYSTEM C define and use it where appropriate.
Forcing the use of a dedicated header to replace pcap.h is
unnecessary code and mental overhead in this case. We can
use config.h instead for the same purpose of defining a
macro symbol before including pcap.h.
The packet loss column has been sorting on a private variable
that is never set(?!) and also is unsigned whereas the actual
lost number is signed. Get the calculated packet loss number
and sort by that. (Should this be sorting by the total number or
the percentage, since the column displays both? Total number is
first so let's use that.)
This should probably be some kind of Model/View instead.
Fix#16785.
The ShowAs enum should stay in the same order as the Items
are added to the ShowAs combobox, because setCurrentIndex()
is used with the enum values, e.g. when setting the value to
"Show As Image" when the bytes are an image.

It is fine to dissect and cache columns data during color dissection if
it won't evict already cached data. There is rather high probability of
using the column data because color information is dissected in order.
The personal extcap folder $XDG_CONFIG_DIR/wireshark on Linux is
inconsistent with the global extcap folder (lib/wireshark/extcap)
and personal plugins folder (.local/lib/wireshark/plugins) and also
the configuration folder should not contain architecture-specific files.
The extcap personal folder is changed from:
.config/wireshark/extcap
to:
.local/lib/wireshark/extcap
QItemSelectionModel tracks both the selected index and the
current index.
PacketList redraws when the *selected* index changes, not
the current index. Clearing the current index, and then marking
the same packet as selected and current fires currentChanged but
not selectionChanged. So drawCurrentPacket needs to call
clearSelection(), not clearCurrentIndex(), in order to trigger
a redissection of the currently selected packet and update
the packet details.
For example, if you mark or unmark the currently selected frame,
this causes the packet details to update. Cf 52955b9c43,
which fixed the same issue but for Find Packet.
Fix#14330.
Only TCP uses fragments, but we don't need to check FOLLOW_TCP
because the fragments pointers exist but are null if not being
used. See the similar code in epan/follow.c
Part of making it simpler for dissectors to register with Follow.
The websocket protocol masking feature makes follow TCP stream
on websocket traffic show masked payload. To easily view unmasked
and reassembled websocket payload add follow websocket stream
support.
Return the percentage in the UNFORMATTED_DISPLAYDATA converted
from our string so it it compares properly with an equality filter.
Use QVariant comparisons where appropriate so that Filter by
works as expected with types that are not integers, such as doubles
the City/Country strings from GeoIP, or when absolute start time
is used for conversation starts.
Fix#18738.
Obtain the capture file read lock when computing protocol hierarchy
stats to prevent segfaulting if the file is closed.
The protocol hierarchy stats are always computed on all the packets
of the current file that pass the current filter, so don't let it run
until a read or rescan is complete.
Since the protocol hierarchy stats use the common progress bar,
these two changes keep it from hijacking the progress bar when a
rescan is in progress, which led to anomolies with the stop button
behavior and clearing the progress bar when the stats were done
(but not the temporarily paused rescan.)
Make the stop button actually stop the protocol hierarchy stats.
In the future, the protocol hierarchy stats could perhaps use
process_specified_records from file.c
Fix#18787. Fix#18788.
ElidedLabel escapes HTML after !9261, so use its own methods to make text
small and italicized instead of passing in rich text.
IOGraphDialog used to make an error message, if it existed, bold.
Perhaps ElidedLabel should have a way to have prepended bold
text for such usage.
Autoset "Limit to display filter" if a display filter is
present when the dialog is open, but do not re-enable it each
time the widget is updated, if the user has unchecked it.

Fix#18461
QVariant canConvert<double>() does not test that a particular QVariant
value can be converted to a double, but only that at least some values
of that type can convert. (Just checking the type is much faster than
actually trying the conversion; this is why convert() has a boolean
output parameter as well.) It thus always returns TRUE for strings even
for strings that fail to convert, and is not by itself a useful test
when trying to sort unknown types.
Luckily, we don't need to test this anyway. Set the default data role used
for sorting to UNFORMATTED_DISPLAYDATA, so the parent QSortFilterProxyModel
will handle QVariants that are numbers appropriately. In particular,
this makes the GeoIP city and country column strings in the Endpoints
table sort correctly.
Fix#18749
When converting from our columns as displayed to the canonical
list of columns, add 1 for the missing conversation ID if it
is not present (as opposed to if it is present.) Also change the
test for the total packets to account for the new conversation ID
column.

We want to return with failure when the number of entries in
the row we're trying to append is greater than the number of
columns, not less than the number of rows in the table.
The IO Graph is the only place that uses appendEntry, and this
allows adding IO Graphs past the tenth graph.
Fix#18762
Make the "ninja install" target in the MINGW64 shell work and
allow Wireshark to run from the msys2 installation, besides
the build directory.
To clarify the names used here MSYSTEM is the distribution with a
Linux-like environment for Windows. MINGW is the toolchain.
It is possible to use MinGW without MSYS2 and we generally select
the CMake variables WIN32/MSVC/MINGW/USE_MSYSTEM taking that into
consideration but that WIN32+MINGW platform is not supported at the
moment and it's unlikely to be supported in the near future.
Instead of connecting ColoringRulesDialog's buttonBox accepted()
signal to two different slots (once in the .ui file, and one
automatically from a name), accept the dialog only after writing
the colors.
This prevents starting to recolor the PacketList before the new color
list has been been written.
Fix#12475. Fix#15471.
The filterPackets method calls file.c/cf_filter_packets,
which calls rescan_packets, which sends signals when done that
eventually calls the PacketList::captureFileReadFinished
PacketList::captureFileReadFinished invalidates all the column
strings after the rescan may have updated their information
(e.g., delta time to previous displayed packet), so it is not
necessary to reset the column strings a second time explicitly
in filterPackets.
Commit 38cde83a5c added the reset
to filterPackets, but commit bbe5fc1028
added the invalidateAllColumnStrings to captureFileReadFinished
that made the prior commit unnecessary.
Introduce a preference for the number of rows whose column text can
be cached, and allow sorting of the packet list only when the
number of displayed rows can fit in the cache. This preference only has
an effect for sorting based on columns that require dissection and
caching the column text. This reduces the number of dissections from
O(N log N) to N. Subsequent sorts are even faster.
Columns based on frame data are unaffected, as they sort much faster
as dissection is not required.
Set the size of the QCache introduced in 8c6854fb65 based
on this preference.
Send a temporary status message to the status bar if we try to sort
but there are too many rows, explaining why sorting did not happen and
that the layout preferences can be changed.
Ping #18741
When dissectors register for Follow Stream, have them register a
function for finding the next valid sub stream id for a given
stream and substream id pair. This function is NULL if the dissector
does not use sub stream IDs.
Use this function in follow_stream_dialog to update the sub stream
id widget (and use the absence of the function to disable and hide
the widget.) Use this function in the CLI tap-follow to determine
whether to parse a sub stream id from the command line options.
This removes the dependencies on epan/dissectors from the Qt
follow_stream_dialog, and gets us closer to having dissectors
being able to register for Follow Stream without having to update
anything in the common source code.
Remove MINIMIZE_STRING_COPYING define because the code does not even
compile anymore. Do not cache strings when ensuring rows are colorized
to avoid thrashing cache. Store column data only for last 500 accessed
records to ensure there is upper bound for the cache size.
Fixes#18741
Display it as a pathname in the native format (e.g., C:\this\is\wrong),
not as the path component of the URL supplied (e.g., /C/this/is/wrong).
Fixes some confusion that appeared in a comment in #15592 (but not the
underlying bug - fixing that bug should prevent that dialog from popping
up in the first place).
