John Thacker 1b82eda9eb epan: Register dynamic column fields and make them filterable ... Make the text of each registered column a FT_STRING field that can be filtered, prefixed with _ws.col - these work in display filters, filters in taps, coloring rules, Wireshark read filters, and in the -Y, -R, -e, and -j options to tshark. Use them as the default "Apply as Filter" value for the columns that aren't handled by anything else currently. Because only the columns formats that actually correspond to columns get filled in (invisible columns work), register and deregister the fields when the columns change. Use the lower case version of the rest of the COL_* define for each column as the field name. This adds a number of conditions to "when are the columns needed", including when the main display filter or any filter on a tap is using one of these fields. Custom columns are currently not implemented. For custom columns, the tree then has to be further primed with any fields used by the custom columns as well. (Perhaps that should happen in epan_dissect_run() - are there any cases where we construct the columns and don't want to prime with any field that custom columns contains? Possibly in taps that we know only use build in columns.) Thus, for performance reasons, you're better off matching an ordinary field if possible; it takes extra time to generate the columns and many of them are numeric types. (Note that you can always convert a non-string field to a string field if you want regex matching, consult the *wireshark-filter(4)* man page.) It does save a bit on typing (especially for a multifield custom column) and remembering the column title might be easier in some cases. The columns are set before the color filters, which means that you can have a color filter that depends on a built-in column like Info or Protocol. Remove the special handling for the -e option to tshark. Note that the behavior is a little different now, because fixed field names are used instead of the titles (using the titles allowed illegal filter names, because it wasn't going through the filter engine.) For default names, this means that they're no longer capitalized, so "_ws.col.info" instead of "_ws.col.Info" - hopefully a small price in exchange for the filters working everywhere. The output format for -T fields remains the same; all that special handling is removed (except for remembering if someone asked for a column field to know that columns should be constructed.) They're also set before the postdissectors, so postdissectors can have access. Anything that depends on whether a packet and previous packets are displayed (COL_DELTA_TIME_DIS or COL_CUMULATIVE_BYTES) doesn't work the way most people expect, so don't register fields for those. (The same is already true of color filters that use those, along with color filters that use the color filter fields.) Fix #16576. Fix #17971. Fix #4684. Fix #13491. Fix #13941.		2023-07-25 00:49:52 +00:00
