From 2f3a76c569e5efad54520613315c0d29512ce69c Mon Sep 17 00:00:00 2001 From: Carl Worth Date: Wed, 11 May 2011 12:34:13 -0700 Subject: [PATCH] Remove some variables which were set but not used. gcc (at least as of version 4.6.0) is kind enough to point these out to us, (when given -Wunused-but-set-variable explicitly or implicitly via -Wunused or -Wall). One of these cases was a legitimately unused variable. Two were simply variables (named ignored) we were assigning only to squelch a warning about unused function return values. I don't seem to be getting those warnings even without setting the ignored variable. And the gcc docs. say that the correct way to squelch that warning is with a cast to (void) anyway. --- lib/message.cc | 2 -- notmuch-new.c | 3 +-- notmuch-tag.c | 4 +--- 3 files changed, 2 insertions(+), 7 deletions(-) diff --git a/lib/message.cc b/lib/message.cc index ecda75af..a5a65e21 100644 --- a/lib/message.cc +++ b/lib/message.cc @@ -213,7 +213,6 @@ _notmuch_message_create_for_message_id (notmuch_database_t *notmuch, { notmuch_message_t *message; Xapian::Document doc; - Xapian::WritableDatabase *db; unsigned int doc_id; char *term; @@ -233,7 +232,6 @@ _notmuch_message_create_for_message_id (notmuch_database_t *notmuch, if (notmuch->mode == NOTMUCH_DATABASE_MODE_READ_ONLY) INTERNAL_ERROR ("Failure to ensure database is writable."); - db = static_cast (notmuch->xapian_db); try { doc.add_term (term, 0); talloc_free (term); diff --git a/notmuch-new.c b/notmuch-new.c index 4874a1c1..744f4ca3 100644 --- a/notmuch-new.c +++ b/notmuch-new.c @@ -64,10 +64,9 @@ static volatile sig_atomic_t interrupted; static void handle_sigint (unused (int sig)) { - ssize_t ignored; static char msg[] = "Stopping... \n"; - ignored = write(2, msg, sizeof(msg)-1); + write(2, msg, sizeof(msg)-1); interrupted = 1; } diff --git a/notmuch-tag.c b/notmuch-tag.c index 60e21e0d..6204ae3c 100644 --- a/notmuch-tag.c +++ b/notmuch-tag.c @@ -25,10 +25,8 @@ static volatile sig_atomic_t interrupted; static void handle_sigint (unused (int sig)) { - ssize_t ignored; - static char msg[] = "Stopping... \n"; - ignored = write(2, msg, sizeof(msg)-1); + write(2, msg, sizeof(msg)-1); interrupted = 1; }
