From 717a07e208ced8ab10c59e70eada67c1a2e8afa2 Mon Sep 17 00:00:00 2001 From: Sergey Poznyakoff Date: Wed, 22 Jan 2014 07:28:02 +0200 Subject: [PATCH] Improve checkpoint interface. * src/buffer.c (format_total_stats): The format arg is const All uses updated. (default_total_format): const * src/checkpoint.c (tty, tty_cleanup): New static. (format_checkpoint_string): New "canned" format %c (checkpoint_finish): New function. * src/common.h (checkpoint_finish): New proto. * src/tar.c (main): Call checkpoint_finish.` --- src/buffer.c | 4 +-- src/checkpoint.c | 76 ++++++++++++++++++++++++++++++++++++++---------- src/common.h | 3 +- src/tar.c | 2 ++ 4 files changed, 66 insertions(+), 19 deletions(-) diff --git a/src/buffer.c b/src/buffer.c index 0f5c76e..648b6ba 100644 --- a/src/buffer.c +++ b/src/buffer.c @@ -514,7 +514,7 @@ print_stats (FILE *fp, const char *text, tarlong numbytes) from the archive), EOL is a delimiter to add at the end of the output line. */ int -format_total_stats (FILE *fp, char **formats, int eor, int eol) +format_total_stats (FILE *fp, const char **formats, int eor, int eol) { int n; @@ -569,7 +569,7 @@ format_total_stats (FILE *fp, char **formats, int eor, int eol) return n; } -char *default_total_format[] = { +const char *default_total_format[] = { N_("Total bytes read"), /* Amanda 2.4.1p1 looks for "Total bytes written: [0-9][0-9]*". */ N_("Total bytes written"), diff --git a/src/checkpoint.c b/src/checkpoint.c index 7637452..3c3ca78 100644 --- a/src/checkpoint.c +++ b/src/checkpoint.c @@ -134,14 +134,14 @@ checkpoint_finish_compile (void) checkpoint_option = DEFAULT_CHECKPOINT; } -static char *checkpoint_total_format[] = { +static const char *checkpoint_total_format[] = { "R", "W", "D" }; static int -getwidth(FILE *fp) +getwidth (FILE *fp) { struct winsize ws; @@ -183,16 +183,19 @@ getarg (const char *input, const char ** endp, char **argbuf, size_t *arglen) return NULL; } +static int tty_cleanup; -static void -format_checkpoint_string (FILE *fp, const char *input, bool do_write, +static const char *def_format = "%s: %t: %T%*\r"; + +static int +format_checkpoint_string (FILE *fp, size_t len, + const char *input, bool do_write, unsigned cpn) { const char *opstr = do_write ?
