From 6e5abd65ae1e883e278d29249784d3bb225c6912 Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Wed, 19 Nov 2008 14:45:09 +0000 Subject: [PATCH] * remote.c (escape_buffer): New. (putpkt_binary, read_frame, getpkt_or_notif_sane_1): Use it. Make sure debug output printing a packet buffer goes through a single fprintf_unfiltered call. * utils.c (vfprintf_unfiltered): If outputting timestamps, end output with a newline if it wasn't going to already. --- gdb/ChangeLog | 9 +++++++ gdb/remote.c | 81 ++++++++++++++++++++++++++++++++++++++++++++++------------- gdb/utils.c | 13 ++++++++-- 3 files changed, 84 insertions(+), 19 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 90599b6..4b2f540 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,12 @@ +2008-11-19 Pedro Alves + + * remote.c (escape_buffer): New. + (putpkt_binary, read_frame, getpkt_or_notif_sane_1): Use it.
