rewrite the tshark capture code almost completely, to use dumpcap instead of it's own pcap functionality.
This works on Win32 and should work on unix/linux (but I'm not sure here). Some stuff needs to be cleaned up, some more may need to be rewritten to specifically work with unix/win32. Futher work needs to be done at:
1. read filters (simply document current behaviour?)
2. event loop polling
3. privileges
4. code cleanup (e.g. in capture_loop.c)
Be prepared that tshark might not work as before / expected at least in the next days!

of the last pcap_open_live() call in the GUI code. Update
README.packaging.

that "-D" and "-L" should produce machine-readable output. Use this to
move an indirect get_pcap_linktype() call from the GUI to dumpcap.

anywhere else). Instead of using getaddrinfo() and getnameinfo(),
promote inet_pton.c and inet_ntop.c to the top level and use those
routines instead.
(It's 2007, for crying out loud. Why is this even an issue?)
svn path=/trunk/; revision=22075
Add a capture_interface_list(), which works similar to
get_interface_list() except that it forks dumpcap instead of calling
the pcap routines directly. Use it in the GUI.
Add a "-I" flag to dumpcap, which prints out verbose interface
information.
Tested under Windows and Linux.

I've also changed the way the secondary error message is transported from former "header message 0 secondary 0" to "header header message 0 header secondary 0" as that might be a bit more clearer, and I'll need it for further development anyway.
I was using this while debugging and not recognizing the real problem - for about four hours :-(. I'll need this feature when doing the interface (and link layer type) browsing later (transferring this data from dumpcap to Ethereal) to get a full blown privilege seperation.

primary and secondary error messages and let the parent worry about how
to display them. This means dumpcap doesn't need stub routines for
generating the formatting tags for the primary and secondary messages.
Have a separate message for capture filter errors, so that the parent
can check whether the capture filter looks like a display filter and
report the appropriate message. This means that dumpcap doesn't need a
stub routine for compiling display filters (a stub routine also means
that Ethereal won't do the check for capture filters that look like
display filters!).

In "capture_input_new_file()", don't call the callbacks unless we
succeed in opening the new file. Have "capture_info_new_file()" return
a success/failure indication.
Improve the message logged when we fail to open the new file if we're
only opening it for the quick packet counts. We really should put up an
alert box and give up on the capture at that point.
svn path=/trunk/; revision=17437
this way, the capture prefix will "logically" group the files together and file browsers will also group them
we may want to move the files into a subdir capture later
svn path=/trunk/; revision=16691
This way, the capture child don't need to now any of the packet_counter things (no epan/packet.h and all alike).
Currently the capture_info code will always open another wiretap file instance to build it's own counter values. This isn't optimized for now (next step: use data from cf_continue_tail() somehow).

Win32 only: wireless: "try switch off promicuous mode"
This way we might get less user questions on the users-mailing list ...
Especially the second one hopefully could save us from a lot of support mails :-)
svn path=/trunk/; revision=16591
to do this, I've added file_util.h to wiretap (would file_compat.h be a better name?), and provide compat_macros like eth_open() instead of open(). While at it, move other file related things there, like #include <io.h>, definition of O_BINARY and alike, so it's all in one place.
deleted related things from config.h.win32
As of these massive changes, I'm almost certain that this will break the Unix build. I'll keep an eye on the buildbot so hopefully everything is working again soon.

cf_cb_file_closing (called before closing a capture file) cf_cb_file_closed will be called afterwards, but both only if a file is really closed as cf_close is called more often ...
If we are closing large capture files (~20MB), the screen looks ugly while the file is closed. Change this so the screen will immediately go back to initial state and a dialog (without buttons) is shown that the file is currently closed. As the operation which takes most of the time to close the file is a single eth_clist_clear call, we can't use a progress bar here.
cf_cb_live_capture_stopping: called when the user wants to stop the capture (toolbar or menu clicked). At least on Win32, the time between this and the actual stop completed can be noticeable (1-2 seconds), so the user doesn't know if the button press did anything at all. Do something similar as above, show a dialog box without buttons to inform that the close is in progress.

use the console_log_handler in main.c for win32 AND unix now
Currently use the log for the capturing engine (only), as I desperately needed a log output for debugging.

various code cleanup and minor bugfixes
Win32: use millisecond resolution in capture_loop, to smooth screen update a bit (500ms instead of 1000ms)
svn path=/trunk/; revision=14059
If this is used together with an option where input files changes too fast (e.g. new file every second), capturing will be (hopefully) stopped.
I've replaced the former capture pipe message format into a somewhat more general format to remove a lot of confusion.

display filename in statusbar while capturing
print_usage banner fixed
cf_cb_live_capture_prepare no longer needed

fix cleanup of old file in capture_input_new_file
fix a tempfile detection bug (named file showed up as tempfile after capture)

most notably:
- moved opening of safe_file to the capture child (capture_loop.c)
- removed save_file_fd from capture_opts (no longer need to have it global)

This is currently still disabled, as we cannot pass all required capture flags to the child process (lack of command line parameters).

object code for libethereal.dll isn't generated by the
makefile in /trunk.
Having no code in /trunk linked into libethereal.dll
anymore, the definition of the macro _NEED_VAR_IMPORT_
can be moved from various source files in /trunk to /trunk/Makefile.nmake .
So do that, too.

instead of already invoking cf_cb_live_capture_started in capture.c, I've introduced the new event cf_cb_live_capture_prepare which only has to set the main windows title and nothing more.

to the "start live capture" callback, and call that from "do_capture()".
When opening a capture file, don't pop up the "What do you want to do?"
pane when closing any existing file you have open, as we're just going
to put the regular view up right after that.

move another two capture related fields (iface and cfilter) from cfile to capture_opts
also move the handling of capture related command line options from main.c to capture.c, that way a future privilege seperated capture program can use the same code to parse it's command line than Ethereal.
It might be even possible to share this parser code even with Tethereal, didn't took a closer look at this.

split drag and drop support out of main.c into new file drag_and_drop.c, to reduce the size of main.c a bit.
Hopefully this won't break unix builds because of missing #include's, I will keep an eye on the buildbot

This includes: all functions in file.h now have a cf_ prefix, will have doxygen tags, will have the capture_file *cf as the first parameter and I tried to generalize the return values for non trivial functions.
Hopefully, I didn't introduced any new bugs, as I had to change a lot of files...

Hopefully the unspecified forward declaration of capture_options_t in main.h is portable, but buildbot will tell me. This way I need the internals of that struct only at the places I really use it.

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.

This matters for "update of list in real time" (sync_mode) only,
as in normal mode you wouldn't otherwise have the possibility
to stop the capture.

add a config.nmake option to control whether to build
libethereal.dll or not;
remove "./wiretap" from PATH to prevent problems due to
wrongly-loaded files;
build dissector.lib with MSVC;
move "print.c" and "ps.c" to the dissector helpers, as "print.c"
imports variables from packet-frame.c and packet-data.c, which
are in libethereal;
move "g711.c" out of the dissector helpers, as they're used only
by Ethereal in a tap, not in Tethereal or in any dissector;
add a .def file for libethereal;
arrange to declare global variables exported from libethereal
with "__declspec(dllimport)" when building programs that import
those variables;
update the NSIS installer.
Make the "configure" script define ETH_VAR_IMPORT as "extern".
