Remove uses of .str(), .c_str() and some other methods of SGPath.
Pass SGPath directly where possible, or explicitly convert to the
appropriate 8-bit encoding.
This adds two wrappers to the generic protocol to help interfacing
small microcontrollers (arduino et. al.)
When receiving binary data over a sequential link, it's hard to tell where a packet
starts and where it ends. Two existing solutions gets implemented with this patch:
KISS (http://www.ka9q.net/papers/kiss.html) originally developed for ham radio
packet radio devices and STX/ETX byte stuffing.
This adds only the OUT direction, IN will be implemented over the next weeks.
For implementation details on the client (microcontroller's) side, check out
http://gitorious.org/flightgear-pmpt/cmpt/
This implementation is used in the c172fg project to be presented at FSweekend 2013.
Simgear contains a new helper to validate format
strings for potentially dangerous replacements, use
it to fix the issues raised by Debian bug trackers.
ASCII protocols consisting of a single chunk only (one variable per line)
would not work when no "separator" was defined.
Also add error message for protocols with more than one var per line which
are missing a separator...
Replace SG_GENERAL by more specific log classes in many places.
Allow "," to separate logging classes (using "|" is odd on the
command-line).
Also add new option to make logging more useful for developers.
You can use:
--log-level=debug --log-class=environment
to only get environment debug messages, or
--log-level=debug --log-class=sound,ai
to only get debug messages related to the sound or AI subsystem.
gcc -Wall -Werror turned up some problems with the type-punning of pointers
used to write the message buffer; it turns out that truncated ints were being
written to the message buffer when values needed to be swapped to network byte
order.
- support optional <preamble> and <postamble> which are written right
after opening and before closing respectively. This can be used for a header
line or an XML header.
- unescape <preamble>, <postamble>, <format>, <line_separator>, <var_separator>
so that \t, \n, \r, \f, \v, \xnn, \nnn can be used directly (\a and \b are
ignored; use \\ for the backslash) The long names ("carriagereturn") are still
supported for <var_separator>, but one can just use \r, or \r\n too.
- don't abort when a chunk doesn't have a <node>. This is useful for adding
constant chunks which consist only of a <format>, such as XML tags.
