annotate lib-src/make-dump-id.c @ 5853:1044acf60048
Revert part of Jerry's December 2014 that broke gnuclient on some OS X.
lib-src/ChangeLog addition:
2015-03-08 Aidan Kehoe <kehoea@parhasard.net>
* gnuserv.c (echo_request):
No longer close the file handle unconditionally, leave this to the
individual socket types.
* gnuserv.c (handle_internet_request):
Close the file handle here.
* gnuserv.c (handle_unix_request):
Don't close the file handle here, document why (it broke gnuclient
under OS X). It should actually be OK, but my suspicion is that
the issues is that the Unix (local) domain sockets are still
underdocumented compared to the internet sockets.
