filter to search forward or backward in the list of displayed frames for
a matching frame.
When filtering the display, readjust the display to show the "current"
frame if it passed the display filter. When a file is read in, the
first frame becomes the "current" frame; when a frame is selected, it
becomes the "current" frame, and remains so *even if you unselect it*,
until another frame is selected.
Select the first frame when a file is read in.
Disable most of the "Display" and "Tools" menu items if there's no
current capture file, and enable the relevant ones if there is.

than a command name of "ethereal-dump-fields", to decide whether to run
as normal Ethereal or to just dump out the list of fields that can be
used in a display filter.
This allows us to continue to make that check without doing the regular
command line flag parsing (which we don't want to do, as we don't want
to call "gtk_init()" before making that check, as "gtk_init()" tries to
open an X display, and some people want not to have to have X running in
order to build Ethereal, or want not to have Ethereal try to open an X
connection over a slow line if it's just going to print field names to
the standard output), without having to make a link to "../ethereal"
from the "doc" directory (said link couldn't be a hard link, as ATK
apparently disallows hard links between directories, and I have the
vague impression that a symbolic link might cause other problems).

the base for numbers to be displayed in, bitmasks for bitfields, and blurbs
(which are one or two sentences describing the field).
proto_tree_add*() routines now automatically handle bitfields. You tell
it which header field you are adding, and just pass it the value of the
entire field, and the proto_tree routines will do the masking and shifting
for you.
This means that bitfields are more naturally filtered via dfilter now.
Added Phil Techau's support for signed integers in dfilters/proto_tree.
Added the beginning of the SNA dissector. It's not complete, but I'm
committing it now because it has example after example of how to use
bitfields with the new header_field_info struct and proto_tree routines.
It was the impetus to change how header_field_info works.

is true. The test for truth now becomes a test for existence. The dfilter
grammar no longer recognizes 'true' and 'false', since you can now check
a boolean field via:
tr.sr
or by its negation:

filtered state. The display filter text entry widget is left in its
original state, so an ENTER can reset the packet list. The manpage has
been changed to mention this.

the "Open File" dialog box (the "Open File" dialog box equivalent of the
"-R" flag). Have "load_cap_file()" take the filter expression as an
argument, and make the global "rfilter" into a member of a
"capture_file" structure.
When reading a temporary capture file after a live capture, don't apply
any filter.
Move the code that pops up error boxes on file opens when reading a
capture file back to "load_cap_file()"; it also pops up error boxes if
the filter expression can't be parsed.
Don't enable "File/Save" or "File/Save As..." if an attempt to read a
capture file fails - if there was already an open capture file, it was
closed by "load_cap_file()", so we no longer have an open file to save.

glossary of display filter symbols, just as it does with "-G", except
that, as it can discover that it was so invoked before even looking at
the command-line arguments, it needn't even bother calling "gtk_init()"
to process those command-line arguments GTK+ cares about, and thus
needn't do any X stuff at all when so invoked.
That allows Ethereal to be built in an environment where you don't have
an X server, and, if your connection to your X server is slow, allows
you to built it faster.
Get rid of the "-G" flag, as it had only a somewhat specialized use.

as it standed depends on your lex being flex, but that only matters if you're
a developer. The distribution will include the dfilter-scanner.c file, so
that if the user doesn't modify dfilter-scanner.l, he won't need flex to
re-create the *.c file.
The new lex scanner gives me better syntax checking for ether addresses. I
thought I could get by using GScanner, but it simply wasn't powerful enough.
All operands have English-like abbreviations and C-like syntax:
and, && ; or, || ; eq, == ; ne, != ; , etc.
I removed the ETHER_VENDOR type in favor of letting the user use the [x:y]
notation: ether.src[0:3] == 0:6:29 instead of ether.srcvendor == 00:06:29
I implemented the IPXNET field type; it had been there before, but was
not implemented. I chose to make it use integer values rather than byte
ranges, since an IPX Network is 4 bytes. So a display filter looks like this:
ipx.srcnet == 0xc0a82c00
rather than this:
ipx.srcnet == c0:a8:2c:00
I can supposrt the byte-range type IPXNET in the future, very trivially.
I still have more work to do on the parser though. It needs to check ranges
when extracting byte ranges ([x:y]) from packets. And I need to get rid
of those reduce/reduce errors from yacc!

capture to a file or printer. This should eventually get the ability to
print either all the packets or only the packets selected by the display
filter, and possibly also the ability to print only packets M through N.
Get rid of "cur" member of "capture_file" structure; nobody used it.
There's no need to pass a pointer to a "dialog_button" variable to
"simple_dialog()" for the error boxes displayed if a file copy or move
fails; that dialog box is just a message box and has only an "OK"
button.

Make the descriptions of all options full sentences (if an option sets
XXX, describe it as "Sets XXX" rather than just "XXX"); some were, some
weren't.
Note that "-f" sets the *capture* filter expression.
Don't say that Ethereal can read only "libpcap"-format files; it can
read other formats (using "wiretap" to read capture files is no longer
an option, it's what Ethereal always uses).

suggestion, this new method using a static array should use less memory
and be faster. It also has a nice side-effect of making the source-code
more readble, IMHO.
Changed the print routines to look for protocol proto_data instead of
looking at the text label as they did before, hoping that the data hex
dump field item starts with "Data (".
Added the -G keyword to ethereal to make it dump a glossary of display
filter keywords to stdout and exit. This data is then formatted with
the doc/dfilter2pod perl program to pod format, which is combined
with doc/ethereal.pod.template to create doc/ethereal.pod, from which
the ethereal manpage is created. This way we can keep the manpage up-to-date
with a list of fields that can be filtered on.
