2014-10-07No need for WTAP_ERR_CANT_READ.Guy Harris1-6/+3
Unlike the standard I/O routines, the code we introduced that supports fast random seeking on gzipped files will always supply some specific error code for read errors, so we don't need WTAP_ERR_CANT_READ. Add WTAP_ERR_CANT_WRITE for writing, as we're still using the standard I/O routines for that. Set errno to WTAP_ERR_CANT_WRITE before calling fwrite() in wtap_dump_file_write(), so that it's used if fwrite() fails without setting errno.

Pcap-ng files don't have a per-file time stamp resolution, they have a per-interface time stamp resolution. Add new time stamp resolution types of "unknown" and "per-packet", add the time stamp resolution to struct wtap_pkthdr, have the libwiretap core initialize it to the per-file time stamp resolution, and have pcap-ng do the same thing with the resolution that it does with the packet encapsulation. Get rid of the TS_PREC_AUTO_XXX values; just have TS_PREC_AUTO, which means "use the packet's resolution to determine how many significant digits to display". Rename all the WTAP_FILE_TSPREC_XXX values to WTAP_TSPREC_XXX, as they're also used for per-packet values.

2014-03-28Allow chained calls with Lua TreeItem functions, and fix a couple of minor ↵Hadriel Kaplan5-23/+121
errors. A common Lua idiom is to use chained calls, i.e. tree:foo():bar():choo(). This actually works for tree:add() because it returns the new child tree item which is then the one being applied to the next chained call. But it doesn't work beyond that for things like set_generated() and so on. So this commit fixes that. This also fixes the Lua tree:add() function for the FT_BOOL type to let it be a Lua boolean value. And it reverts a previous change to Struct.tohex() to allow coercion of the argument.

This adds the global and personal plugins directories to the package.path setting in Lua, so doing 'require' will work properly.

2014-03-26Add various functions for Lua directory handling and path infoHadriel Kaplan10-197/+465
This adds new functions to get plugins path info, find out if a directory exists, make a new one, remove one, etc. It also creates a file environment for user-supplied Lua scripts, to prevent global variable contamination as well as supply the script-specific file name. Some other minor cleanup was done as I found them. A new testsuite was added to test the existing and new directory functions.
