2014-03-22Add way for Lua file reader to save state per file read/write opsHadriel Kaplan3-261/+528
Lua can create a file reader/writer, to open new capture file formats or write to new ones. To save local state, it can save things in Lua itself; but since there can be multiple open files at the same time (for example during a reload), the Lua script won't know for which file and state its read/write functions are being invoked for. To remedy this, and also provide a convenient way to store such state, this commit adds the ability for a Lua script to store a Lua table in the wtap/wtap_dumper's priv data member, just like C-code-based reader/writers do.

2014-03-19Fix lua file testsuite not working and weak heuristic readers not being ↵Hadriel Kaplan4-11/+31
registered The testsuite for Lua file reader/writer uses the acme_file.lua script to generate a pcapng file from an Acme sipmsg.log file. It then compares the tshark verbose output of this new pcapng file to a sip.pcapng file in the test/captures directory that was previously made. Unfortunately, the acme_file.lua script generates a timestamp based on local system timezone, rather than UTC, so the testsuite fails if not run in the EST timezone where the sip.pcapng file was originally made. This has now been fixed. Also, trying to register new weak heuristic readers fails because the GArray is terminated with a NULL-based row without Glib knowing about that. So this commit changes it to let Glib handle the NULL-terminated row, so that appending takes it into account automatically.

This adds the ability for Lua scripts to register heuristic dissectors for any protocol that has registered a heuristic dissector list, such as UDP, TCP, and ~50 others. The Lua function can also establish a conversation tied to its Proto dissector, to avoid having to check the heuristics for the same flow. The example dissector in the testsuite has also been enhanced to include a heuristic dissector, to verify the functionality and provide an example implementation.

That's because I had set the class' metatable __index metamethod to point to the class table, which of course has the metatable with the __index metamethod, causing a lookup loop. Blech.

2014-03-10Add GLib's regex library into LuaHadriel Kaplan8-2/+1465
While Lua's built-in pattern support is ok for simple things, many people end up wanting a real regex engine. Since Wireshark already includes the GLib Regex library (a wrapper for PCRE), it makes sense to expose that library to Lua scripts. This has been done using Lrexlib, one of the most popular regex bindings for Lua. Lrexlib didn't support binding GLib's Regex in particular - it does for PCRE but GLib is a different API - so I've done that. A fairly thorough testsuite came along with that, which has been incorporated into the wireshark wslua testuites as well in this commit.

2014-02-25Fix bug 6357: Lua all_field_infos() broken within tap/listenerHadriel Kaplan1-3/+70
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().

2014-02-21Fix bug 9790: Lua: wslua allows duplicate field registrationHadriel Kaplan2-0/+594
As discussed in bug 3513 and 9709, one can register more than one new ProtoFields for the same field name. Of course C-code can do that too, and does a LOT apparently, but if they're not similar ftypes then things can get scrweed up in display filters. So this change prevents duplicate field registration of dissimilar ftypes. The similarity is based on the discussion on the mailing list, and the listing in README.developer has been updated to refelect that as well. Also, this change adds a testscript for Proto/ProtoFields.

OK, in all fairness this does a bit more than just fix that bug. It also adds a 'Int64()' and 'UInt64()' __call metamethods. I generally dislike using __call metamethods, because they're often unintuitive (for example the wireshark Field and FielInfo use this in a bizarre fashion). But this happens to be a perfect use for it, and very natural, imho. Another change is to make the metatables of classes visible to scripts. There was never really a good reason not to make them visible, and they have to be visible to do things like use __call on a plain table... not to mention I need them to be visible to run test scripts verifying evrything is kosher. I also updated the test suite to test for the div/mod by zero.

This change adds a host of functions and operators to the existing Int64 (gint64) and UInt64 (guint64) classes, to enable true 64-bit integer support on par with native Lua numbers. A test script is also provided, which tests the functions/operators.
