Cast away some implicit 64-bit-to-32-bit conversion errors due to use of
sizeof.
Cast away some implicit 64-bit-to-32-bit conversion errors due to use of
strtol() and strtoul().
Change some data types to avoid those implicit conversion warnings.
When assigning a constant to a float, make sure the constant isn't a
double, by appending "f" to the constant.
Constify a bunch of variables, parameters, and return values to
eliminate warnings due to strings being given const qualifiers. Cast
away those warnings in some cases where an API we don't control forces
us to do so.
Enable a bunch of additional warnings by default. Note why at least
some of the other warnings aren't enabled.
randpkt.c and text2pcap.c are used to build programs, so they don't need
to be in EXTRA_DIST.
If the user specifies --enable-warnings-as-errors, add -Werror *even if
the user specified --enable-extra-gcc-flags; assume they know what
they're doing and are willing to have the compile fail due to the extra
GCC warnings being treated as errors.

Move the packet_char_enc enum from packet.h to frame_data.h. Make the
encoding flag a packet_char_enc and make it one bit.
Get rid of the "cfile" global in a few places. C++-ize some of the font
code. Clean up some variable names.

This commit reduces size (from 144B to 128B on AMD64) of frame_data structure.
Part of bug 5821: Reduce per-packet memory requirements.
svn path=/trunk/; revision=45071
make Save-As/Displayed/All-Packets save not only the displayed packets but
also any other packets needed (e.g., for reassembly) to fully dissect the
displayed packets.
This works only for the "All packets" case; choosing only the Selected packet,
the Marked packets, or a range of packets would require actually storing which
packets depend on which (too much memory) or going through the packet list many
times (too slow). Also, this behavior is always the case: you can't save the
displayed packets without their dependencies (I don't see why this would be
desirable).
So far this is done for SCTP and things using the reassembly routines (TCP has
been tested).
The Win32 dialog was modified but hasn't been tested yet.
One confusing aspect of the UI is that the Displayed count in the Save-As
dialog does not match the number of displayed packets. (I tried renaming the
button "Displayed + Dependencies" but it looked too big.) The tooltip tries
to explain this and the fact that this works only in the All-Packets case;
suggestions for improvement are welcome.
Implementation details:
Dissectors (or the reassembly code) can list frames which were needed to
build the current frame's tree. If the current frame passes the display
filter then each listed frame is marked as "depended upon" (this takes up the
last free frame_data flag).
When performing a Save-As/Displayed/All-Packets then choose packets which
passed the dfilter _or_ are depended upon.

by Wiretap, to indicate whether certain fields in that structure
actually have data in them.
Use the "time stamp present" flag to omit showing time stamp information
for packets (and "packets") that don't have time stamps; don't bother
working very hard to "fake" a time stamp for data files.
Use the "interface ID present" flag to omit the interface ID for packets
that don't have an interface ID.
We don't use the "captured length, separate from packet length, present"
flag to omit the captured length; that flag might be present but equal
to the packet length, and if you want to know if a packet was cut short
by a snapshot length, comparing the values would be the way to do that.
More work is needed to have wiretap/pcapng.c properly report the flags,
e.g. reporting no time stamp being present for a Simple Packet Block.

This is POC we may want to have more efficient use of the frame data
structure etc. But this allows for work to be done on the GUI to actually add comments.
svn path=/trunk/; revision=40969
This lets us get rid of the per-frame_data-structure prev and next
pointers, saving memory (at least according to Activity Monitor's report
of the virtual address space size on my Snow Leopard machine, it's a
noticeable saving), and lets us look up frame_data structures by frame
number in O(log2(number of frames)) time rather than O(number of frames)
time. It seems to take more CPU time when reading in the file, but
seems to go from "finished reading in all the packets" to "displaying
the packets" faster and seems to free up the frame_data structures
faster when closing the file.
It *is* doing more copying, currently, as we now don't allocate the
frame_data structure until after the packet has passed the read filter,
so that might account for the additional CPU time.
(Oh, and, for what it's worth, on an LP64 platform, a frame_data
structure is exactly 128 bytes long. However, there's more stuff to
remove, so the power-of-2 size is not guaranteed to remain, and it's not
a power-of-2 size on an ILP32 platform.)
It also means we don't need GLib 2.10 or later for the two-pass mode in
TShark.
It also means some code in the TCP dissector that was checking
pinfo->fd->next to see if it's NULL, in order to see if this is the last
packet in the file, no longer works, but that wasn't guaranteed to work
anyway:
we might be doing a one-pass read through the capture in TShark;
we might be dissecting the frame while we're reading in the
packets for the first time in Wireshark;
we might be doing a live capture in Wireshark;
in which case packets might be prematurely considered "the last packet".
#if 0 the no-longer-working tests, pending figuring out a better way of
doing it.

encapsulation/data-link type to 16 bits, and shuffle some fields to
eliminate some unnecessary padding - the net result should be no change
in the structure size for 32 bits and a few bytes removed for 64 bits.
This allows more encapsulation types - we've just about run out of the
ones that fit in a signed 8-bit integer - and thus should fix bug 5025.

This patch optimizes the data source name processing in add_new_data_source()
by delaying it. We now simply store the constant string and lazily compute the
name when needed. This gives a performance boost because we only need the name
if we have multiple data sources.

- Change apply / prepare / ... as filter to use the field's value, which
is now stored in fdata as well as cinfo. Now we don't have to reprocess
the entire packet list when using these features. This also prevents
the use of these features from overwriting custom column information.
(custom columns can now be used in apply / prepare ... as filter)
- Break col_expr and col_expr_val out into a struct that is included not only
in cinfo, but now also fdata.
- Have col_custom_set_fstr() quote FT_STRING & FT_STRINGZ when storing the
col_expr_val value (for filter creation).

Fix for bug #491: Unexpected frame.time_delta behavior
This patch ... fixes bug 491. It does this by changing the
behaviour of the frame.time_delta field so it reflects the delta
time between captured packets (tshark already did this). To keep
the delta time between displayed packets, the field
frame.time_delta_displayed is created.

"unknown" for frame numbers. Note that in epan/frame_data.h, and make
the frame number in experts unsigned, and use 0 for "unknown", and
display it as an unsigned number - and, if it's 0, don't display it at
all.
Fix the signature of "expert_dlg_draw()" to match what a tap's draw
routine's signature is expected to be.

I've done more than a day to change the timestamp resolution from microseconds to nanoseconds. As I really don't want to loose those changes, I'm going to check in the changes I've done so far. Hopefully someone else will give me a helping hand with the things left ...
What's done: I've changed the timestamp resolution from usec to nsec in almost any place in the sources. I've changed parts of the implementation in nstime.s/.h and a lot of places elsewhere.
As I don't understand the editcap source (well, I'm maybe just too tired right now), hopefully someone else might be able to fix this soon.
Doing all those changes, we get native nanosecond timestamp resolution in Ethereal. After fixing all the remaining issues, I'll take a look how to display this in a convenient way...
As I've also changed the wiretap timestamp resolution from usec to nsec we might want to change the wiretap version number...

they have LF at the end of the line on UN*X and CR/LF on Windows;
hopefully this means that if a CR/LF version is checked in on Windows,
the CRs will be stripped so that they show up only when checked out on
Windows, not on UN*X.

filter's colors" bug, by storing the pointer to the matching color_filter_t
structure in the frame_data structure.
Replace "frame" and "frames" by "packet" and "packets" in many places.
svn path=/trunk/; revision=9607
One can now select a packet and mark it as a TimeReference packet using the menu.
A TimeReference packet will be indicated by having all timestamp related column entries replaced by the string *REF*
A TimeReference packet will always be displayed in the packet pane, and overrides any display filters.
When a frame is a TimeReference frame, all later frames will calculate the TimeRelativeToFirstPacket relative to the timestamp of the TimeReference frame instead of the first frame of the capture.
You can have any number of TimeReference frames you like.

Ethereal presents a column to display culmulative bytes into the capture.
A new column type is added : Culmulative Bytes.
While PacketLength column type specifies the number of bytes in the current packet,
Culmulative Bytes specifies the culmulative number of bytes from the start of the capture.
