2015-09-11dfilter: Add membership operatorJeffrey Smith1-0/+79
Added a new relational test: 'x in {a b c}'. The only LHS entity supported at this time is a field. The generated DFVM operations are equivalent to an OR'ed series of =='s, but with the redundant existence tests removed.

2003-12-06From Olivier BiotGilbert Ramirez1-1/+5
New "matches" operater in display filter language. Uses PCRE. If a "matches" operator is found in a dfilter while libpcre has not been used to build the binary, then an exception is thrown after using dfilter_fail() to set an apporporiate error message. svn path=/trunk/; revision=9182

filter, as in "ip.src == x.x.x.x || ip.src == y.y.y.y". My previous change to allow filtering on multiple fields of the same name moved some code into the wrong block within the function, causing the error. svn path=/trunk/; revision=6544
2002-10-16Make the dfilter code support multiple header_field_info's withGilbert Ramirez1-29/+47
the same name (abbreviation). Thus, if multiple protocols or fields are registered with the same name, you can still filter on the name and have the filtering work as expected. svn path=/trunk/; revision=6434

2002-03-02From Joerg Mayer: get rid of "-Wno-unused" flag in some configureGuy Harris1-2/+2
scripts, and check in changes to add _U_ to some unused arguments (some other should perhaps be used, so we leave the _U_ out so that the warnings serve as a reminder to check those). svn path=/trunk/; revision=4848
2002-01-21Include files from the "epan" directory and subdirectories thereof withGuy Harris1-4/+3
"epan/..." pathnames, so as to avoid collisions with header files in any of the directories in which we look (e.g., "proto.h", as some other package has its own "proto.h" file which it installs in the top-level include directory). Don't add "-I" flags to search "epan", as that's no longer necessary (and we want includes of "epan" headers to fail if the "epan/" is left out, so that we don't re-introduce includes lacking "epan/"). svn path=/trunk/; revision=4586
2001-12-18Provide for per-protocol-tree data in the proto_tree code.Gilbert Ramirez1-2/+48
Put a hash-table of "interesting" fields in the per-proto-tree data. The dfilter code records which fields/protocols are "interesting" (by which I mean, their value or existence is checked). Thus, the proto_tree routines can create special arrays of field_info*'s that are ready for the dfilter engine to use during a filter operation. Also store the "proto_tree_is_visible" boolean, renamed "visible", in the per-proto-tree data. Move epan_dissect_t to its own header file to make #include dependencies easier to handle. Provide epan_dissect_fill_in_columns(), which accepts just the epan_dissect_t* as an argument. epan_dissect_new() needs to be followed by epan_dissect_run() for the dissection to actually take place. Between those two calls, epan_dissect_prime_dfilter() can be run 0, 1, or multiple times in order to prime the empty proto_tree with the "intersesting" fields from the dfilter_t. svn path=/trunk/; revision=4422

svn path=/trunk/; revision=3013
2001-02-01Create a more modular type system for the FT_* types. Put themGilbert Ramirez1-0/+299
into epan/ftypes. Re-write display filter routines using Lemon parser instead of yacc. Besides using a different tool, the new grammar is much simpler, while the display filter engine itself is more powerful and more easily extended. Add dftest executable, to test display filter "bytecode" generation. Add option to "configure" to build dftest or randpkt, both of which are not built by default. Implement Ed Warnicke's ideas about dranges in the new display filter and ftype code. Remove type FT_TEXT_ONLY in favor of FT_NONE, and have protocols registered as FT_PROTOCOL. Thus, FT_NONE is used only for simple labels in the proto tree, while FT_PROTOCOL is used for protocols. This was necessary for being able to make byte slices (ranges) out of protocols, like "frame[0:3]" Win32 Makefile.nmake's will be added tonight. svn path=/trunk/; revision=2967
