Joel Brobecker ecd75fc8ee Update Copyright year range in all files maintained by GDB. 2014-01-01 07:54:24 +04:00
Pedro Alves 533b06003e [gdbserver] Split a new hostio.h file out of server.h.
gdb/gdbserver/
2013-09-05  Pedro Alves  <palves@redhat.com>

	* server.h (handle_vFile, hostio_last_error_from_errno): Move
	to ...
	* hostio.h: ... this new file.
	* hostio.c, server.c, linux-low.c, nto-low.c, spu-low,
	win32-low.c: Include hostio.h.

Pedro Alves d5749ee715 [GDBserver] hostio.c: Fallback to packet buffer size if PATH_MAX is not available.
PATH_MAX is not defined on systems which have no limit on filename
length, such as GNU/Hurd.  As designed, the hostio RSP packets carry
the paths as parameters in the request/reply packets, which themselves
have an upper size limit, so lifting the filename limit completely
would require a redesign with new hostio packets.  While that doesn't
happen, we can at least support filename lengths as long as the packet
buffer can fit.

2013-07-01  Pedro Alves  <palves@redhat.com>

	* hostio.c (HOSTIO_PATH_MAX): Define.
	(require_filename, handle_open, handle_unlink, handle_readlink):
	Use it.

Joel Brobecker 28e7fd6234 Update years in copyright notice for the GDB files.
Two modifications:
  1. The addition of 2013 to the copyright year range for every file;
  2. The use of a single year range, instead of potentially multiple
     year ranges, as approved by the FSF.
