2014-02-25Fix bug 6357: Lua all_field_infos() broken within tap/listenerHadriel Kaplan1-0/+12
The current API for Lua provides a global function "all_field_infos()" which returns all the populated field_info nodes in the current proto_tree. By default all_field_infos() "works", in the literal sense: it returns exactly the fields the previous dissectors of the packet have populated at that instant of time. But of course dissectors don't populate all the applicable fields most of the time, because of the TRY_TO_FAKE_THIS_ITEM optimization where they don't fill in things that aren't needed at the time by a display, color, or tap's dfilter. So this commit offers a way to force the dissectors to populate all the applicable field_infos in the tree, by setting the proto_tree to be visible. Obviously that is going to impact performance, since it basically bypasses the TRY_TO_FAKE_THIS_ITEM optimization; so the patch only does this if the Lua script author told it to explicitly, by adding an argument to Listener.new() and register_postdissector().

2014-01-08TFShark (Terminal Fileshark) v.001. Bug 9607 ↵Michael Mann1-0/+11
(https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=9607) This is a VERY PRELIMINARY version of tfshark. It's an attempt to jumpstart FileShark and its architecture. Right now it's mostly just a very stripped down version of tshark with all of the necessary build modifications (including now building filetap library since tfshark depends on it) This code has helped me identify what I believe to be all of the necessary layers for a complete fileshark architecture. And those layers will slowly be added in time (patches always welcome!). svn path=/trunk/; revision=54646
2013-12-22Avoid including definition of column_info structure in dissectors.Jakub Zawadzki1-3/+3

2013-12-05Initialize the error-reporting routines before scanning for plugins, asGuy Harris1-6/+1
the code to scan for them uses those routines. This means epan_init() no longer takes those routines as arguments - which is just as well, given that the mechanism in question is no longer part of libwireshark, but is part of libwsutil. This should fix bug 9508. svn path=/trunk/; revision=53796

Have it use the report_err.c routines, so it works in console-mode programs. Clean up some comments while we're at it. svn path=/trunk/; revision=27456

The splash screen shows a progress bar and a percentage complete - like the progress dialog. As dissectors are initialised and handed off the name is shown. However, the names of plugin dissectors are not shown. The update to the make-dissector-reg shell script has been tested, though I think generally the python version is used. svn path=/trunk/; revision=21716
2007-01-02Add a WIRESHARK_RUN_FROM_BUILD_DIRECTORY environment variable on UN*X;Guy Harris1-1/+1
if set, and if the program isn't running with additional privileges, it'll treat the directory in which the program is found as the data directory. If, on Windows, the version-number subdirectory of {data directory}\plugins doesn't exist (which is assumed to mean that the program is being run from the build directory), or if, on UN*X, WIRESHARK_RUN_FROM_BUILD_DIRECTORY is set, the plugin directory is the "plugins" subdirectory of the data directory, and all subdirectories of that directory are scanned for plugins, as the "plugins" subdirectory of the build directory contains subdirectories for the plugins; this means that if we're running from the build directory, we'll find the plugins we built in the build tree. When generating the wireshark-filter man page, run tshark with WIRESHARK_RUN_FROM_BUILD_DIRECTORY set, so it uses the plugins from the build to generate the list of filters. svn path=/trunk/; revision=20261
