2019-01-01Add a "failed" return for tap packet routines.Guy Harris1-1/+10
This allows taps that can fail to report an error and fail; a failed tap's packet routine won't be called again, so they don't have to keep track of whether they've failed themselves. We make the return value from the packet routine an enum. Don't have a separate type for the per-packet routine for "follow" taps; they're expected to act like tap packet routines, so just use the type for tap packet routines. One tap packet routine returned -1; that's not a valid return value, and wasn't one before this change (the return value was a boolean), so presume the intent was "don't redraw". Another tap routine's early return, without doing any work, returned TRUE; this is presumably an error (no work done, no need to redraw), so presumably it should be "don't redraw". Clean up some white space while we're at it. Change-Id: Ia7d2b717b2cace4b13c2b886e699aa4d79cc82c8 Reviewed-on: https://code.wireshark.org/review/31283 Reviewed-by: Guy Harris <guy@alum.mit.edu>

2017-12-14Refactor plugin registration and loadingJoão Valverde1-4/+10
Put different types of plugins (libwiretap, libwireshark) in different subdirectories, give libwiretap and libwireshark init routines that load the plugins, and have them scan the appropriate subdirectories so that we don't even *try* to, for example, load libwireshark plugins in programs that only use libwiretap. Compiled plugins are stored in subfolders of the plugin folders, with the subfolder name being the Wireshark minor version number (X.Y). There is another hierarchical level for each Wireshark library (libwireshark, libwscodecs and libwiretap). The folder names are respectively plugins/X.Y/{epan,codecs,wiretap}. Currently we only distribute "epan" (libwireshark) plugins.

When fields have changed the compiled display filter may be invalid or need a recompile to be valid. Filters which are not valid after a recompile is set to a filter matching no packets (frame.number == 0) to indicate that this does no longer match anything. We should probably have a better filter matching no packet for this purpose.
