XML 1.0 allows valid UTF-8 characters, except for the ASCII control
characters other than tab, carriage return, and line feed.
(It does not allow form feed and vertical tab, so the allowed group is
not the same as the standard ctype.h isspace category. It also
allows but discourages DEL (\x7F).)
The characters cannot be included as character references of the
form &#xx; either; there is technically no way to include them.
Escape them as done prior to 89e96c1e77
but continue to leave bytes with the high bit set alone so that
UTF-8 printable characters are not escaped.
Fix#10445
Add a function to get the column text of the nth column, taking
into account whether the column is resolved or unresolved. Use
this function in the GUI, as well as in tshark, when writing
PSML, exporting dissection to PSML, etc., instead of accessing
col_data directly.
This removes the direct accesses of col_data from outside
column.c and column-utils.c
Fix#18168.
Replace:
g_snprintf() -> snprintf()
g_vsnprintf() -> vsnprintf()
g_strdup_printf() -> ws_strdup_printf()
g_strdup_vprintf() -> ws_strdup_vprintf()
This is more portable, user-friendly and faster on platforms
where GLib does not like the native I/O.
Adjust the format string to use macros from intypes.h.
The header ftypes-int.h should not be used outside of epan/ftypes
because it is a private header.
The functions fvalue_free() and fvalue_cleanup() need not and should
not be macros either.
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.
Note that it was impossible to actually overflow
the buffer, and there is a check to flush and restart
if it gets to within a few bytes of the end, but static
analyzers (CID: 1477927) are unlikely to be able to work
this out.
Most of the time, the return value tells us nothing useful, as we've
already decided that we're perfectly willing to live with string
truncation. Hopefully this keeps Coverity from whining that those
routines could return an error code (NARRATOR: They don't) and thus that
we're ignoring the possibility of failure (as indicated, we've already
decided that we can live with string truncation, so truncation is *NOT*
a failure).
It has the "feature" that, if handed a negative value, it might just
exit. gmtime() doesn't have that "feature", and is sufficiently
thread-safe for our purposes; use it instead, and check to make sure it
doesn't return a null pointer.
The previous fix for #17179 still used gmtime_s(); this doesn't, so it's
a better fix for #17179.
Speed functions to print hex bytes, escape XML strings and
print out indents by avoiding specifier calls, and building
larger strings before calling fputs().
Someone mentioned this in the sharkfest chat yesterday.
Also, Ostinato relies upon this when importing from pcap.
An example capture I have has gone from 18 to 11 seconds.
The check in the caller suggests this function can fail. The
assert should not be necessary, then.

The outputs of -T ek and -G elastic-mapping don't match. To be effective
the fields in the mapping report and the fields in the traffic output must
be the same.
2 issues have been fixed. The elastic-mapping requires the parent protocol
to be prepended to the field to match the traffic output. The field "dns.a"
has been changed to "dns_dns_a".
The traffic output prints some fields with a leading "text_". This happens
for some fields that have been created under a text only field. One example
is "dns.a", that was printed as "text_dns_a". This has been fixed by accessing
the parent hfinfo resulting in "dns_dns_a" as other fields for the dns
protocol.

Make the time stamp precision a 4-bit bitfield, so, when combined with
the other bitfields, we have 32 bits. That means we put the flags at
the same structure level as the time stamp precision, so they can be
combined; that gets rid of an extra "flags." for references to the flags.
Put the two pointers next to each other, and after a multiple of 8 bytes
worth of other fields, so that there's no padding before or between them.
It's still not down to 64 bytes, which is the next lower power of 2, so
there's more work to do.

For each occurrence, if there was already an occurrence in the array, we
were just removing it. not freeing what it pointed to.
While we're at it, expand comments. and always check the array size with
"!= 0", not "> 0" - the value is unsigned, so they're equivalent, but
this makes the code more self-consistent.
