When a new display filter is to be applied, don't set "cf.dfilter" or
"cf.dfcode" if the new filter doesn't compile, because the filter
currently in effect will be the one that was last applied - just free up
the text of the new filter, and whatever memory was allocated for the
new filter code.

This means we allocate a new dfilter when a new filter is to be applied,
rather than recycling stuff from the old filter, as we want the old
filter code to remain around if the new filter doesn't compile.

This means that "cf.dfilter" and "cf.dfcode" will be null if there's no
filter in effect.

Have "get_host_ipaddr()" return a Boolean indicating whether it
succeeded or failed, and, if it succeeded, have it fill in the IP
address if found through a pointer passed as the second argument.

Have it first try interpreting its first argument as a dotted-quad IP
address, with "inet_aton()", and, if that fails, have it try to
interpret it as a host name with "gethostbyname()"; don't bother with
"gethostbyaddr()", as we should be allowed to filter on IP addresses
even if there's no host name associated with them (there's no guarantee
that "gethostbyaddr()" will succeed if handed an IP address with no
corresponding name - and it looks as if FreeBSD 3.2, at least, may not
succeed in that case).

Add a "dfilter_fail()" routine that takes "printf()"-like arguments and
uses them to set an error message for the parse; doing so means that
even if the filter expression is syntactically valid, we treat it as
being invalid.  (Is there a better way to force a parse to fail from
arbitrary places in routines called by the parser?)

Use that routine in the lexical analyzer.

If that error message was set, use it as is as the failure message,
rather than adding "Unable to parse filter string XXX" to it.

Have the code to handle IP addresses and host names in display filters
check whether "get_host_ipaddr()" succeeded or failed and, if it failed,
arrange that the parse fail with an error message indicating the source
of the problem.

guy [Thu, 30 Sep 1999 06:50:01 +0000 (06:50 +0000)]
Add a new global flag "capture_child", which is TRUE if we're a child
process for a sync mode or fork mode capture.

Have that flag control whether we do things that *only* the parent or
*only* the child should do, rather than basing it solely on the setting
of "sync_mode" or "fork_mode" (or, in the case of stuff done in the
child process either in sync mode or fork mode, rather than basing it on
the setting of those flags at all).

Split "do_capture()" into a "run_capture()" routine that starts a
capture (possibly by forking off and execing a child process, if we're
supposed to do sync mode or fork mode captures), and that assumes the
file to which the capture is to write has already been opened and that
"cf.save_file_fd" is the file descriptor for that file, and a
"do_capture()" routine that creates a temporary file, getting an FD for
it, and calls "run_capture()".

Use "run_capture()", rather than "capture()", for "-k" captures, so that
it'll do the capture in a child process if "-S" or "-F" was specified
("do_capture()" won't do because "-k" captures should write to the file
specified by the "-w" flag, not some random temporary file).

For child process captures, however, just use "capture()" - the child
process shouldn't itself fork off a child if we're in sync or fork mode,
and should just write to the file whose file descriptor was specified by
the "-W" flag on the command line.

All this allows you to do "ethereal -S -w <file> -i <interface> -k" to
start a sync mode capture from the command line.

file.

This means we start the capture in "main()", rather than in the realize
callback for the main window, so get rid of that callback.

If we're a child process that's just capturing to a file for our parent
to read, however, we shouldn't pop up the top-level window, because
that's our parent's job; when running that child, set its "argv[0]" to a

2) we don't have to invent Yet Another Flag to say "you're the

(We may want to use the name to turn on *all* behaviors that the capture
child, and only the capture child, should exhibit.)
