Mostly functioning proof of concept for #14329. This work is intended to
allow Wireshark to support multiple packet comments per packet.
Uses and expands upon the `wtap_block` API in `wiretap/wtap_opttypes.h`.
It attaches a `wtap_block` structure to `wtap_rec` in place of its
current `opt_comment` and `packet_verdict` members to hold OPT_COMMENT
and OPT_PKT_VERDICT option values.
This functionality has been added in d2a660d8, where its limitations
are described.
Improvements:
* the Substream index menu now properly filters for available stream numbers;
* Follow Stream selects the first stream in the current packet
Known issue (which is still there): if a packet contains multiple QUIC
streams, then we will show data also from streams other than the selected
one (see #16093)
Note that there is no way to follow a QUIC connection.

Clang gives a fatal warning about "explicitly assigning value of
variable of type 'int' to itself". The statement (and the `if` around
it) are redundant, so this removes both.
It is the intention to enable more precise filtering for json. 6 changes were
made for this:
- 'json.member' becomes filterable as a string field with the key of the
member. Before the key was only appended as text but was not filterable.
- Every item gets a field 'path' which allows to filter for elments
which are at a specific position within the json. To make anonymous arrays
visible (no member key) they appear as '[]' in the path. (For example arrays
in arrays)
- Every string, number, true, false, true or null item gets a field
'path_with_value' which combines the path of this element with its value. This
allows a filtering for values of elements at a specific position within the
json.
- Every string, number, true, false, true or null item gets a field
'member_with_value' which combines the key of this element with its value. This
allows a filtering for specific key-values-pairs independently of the position
within the json.
-It is possible to hide 'path', 'path_with_value', 'member_with_value' by
a preference called 'Hide extended path based filtering'.
- If the provided buffer does not start with the json object but has some
leading bytes which does not belong to the json object there is a new option to
ignore these bytes. This behaviour can be enabled by the newly introduced
preference 'Ignore leading non JSON bytes'.
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.
Dependending on version_info is unnecessary and forces an epan
rebuild every time the git commit id changes, which can be slow,
especially with LTO enabled, and again is unnecessary.
Printing the VCS version to the TLS debug log is a minor convenience
that doesn't justify the cost to relink epan with every commit.
We always build the .c files in ui/win32 with Visual C++, so rename
them to .cpp and update CMakeLists.txt to match. Leave the C code mostly
intact for now, but this lets us take advantage of C++ features in the
future if desired.
It is a common use case to look at the signal raw values in hex.
This patch adds this for uint based values. Since the length of
the signal is not necessary 8, 16, 32, or 64 bit, this is done via
append_text.
The Octet string is an outlier amongst DNP3 objects as the variation
doesn't define a specific type of string but the length.
Presiously the length was not displayed in the packet details,
this change adds the length to the object header.
A sub-tlv has a 2-bytes type and a 2-bytes length, that includes
the stlv header. For this reason the full length of a stlv must be
over 4. This must be checked before converting the payload to a
string by subtracting 4 to the length.
Fix: #17459.
It has been added since its length is signed, while the underlying
bytes_to_str uses a size_t, causing an unwanted cast. Basically
passing a len < 0 is pointless.
