From 9a5fa17fd3c4885262e31bf14cf495d02e5f6b27 Mon Sep 17 00:00:00 2001 From: Davi Arnaut Date: Tue, 20 Jul 2010 15:07:36 -0300 Subject: Bug#45288: pb2 returns a lot of compilation warnings on linux Fix warnings flagged by the new warning option -Wunused-but-set-variable that was added to GCC 4.6 and that is enabled by -Wunused and -Wall. The option causes a warning whenever a local variable is assigned to but is later unused. It also warns about meaningless pointer dereferences. client/mysql.cc: Meaningless pointer dereferences. client/mysql_upgrade.c: Check whether reading from the file succeeded. extra/comp_err.c: Unused. extra/yassl/src/yassl_imp.cpp: Skip instead of reading data that is discarded. include/my_pthread.h: Variable is only used in debug builds. include/mysys_err.h: Add new error messages. mysys/errors.c: Add new error message for permission related functions. mysys/mf_iocache.c: Variable is only checked under THREAD. mysys/my_copy.c: Raise a error if chmod or chown fails. mysys/my_redel.c: Raise a error if chmod or chown fails. regex/engine.c: Use a equivalent variable for the assert. server-tools/instance-manager/instance_options.cc: Unused. sql/field.cc: Unused. sql/item.cc: Unused. sql/log.cc: Do not ignore the return value of freopen: only set buffer if reopening succeeds. Adjust doxygen comment to the right function. Pass message lenght to log function. sql/mysqld.cc: Do not ignore the return value of freopen: only set buffer if reopening succeeds. sql/partition_info.cc: Unused. sql/slave.cc: No need to set pointer to the address of '\0'. sql/spatial.cc: Unused. Left for historical purposes. sql/sql_acl.cc: Unused. sql/sql_base.cc: Pointers are always set to the same variables. sql/sql_parse.cc: End statement if reading fails. Store the buffer after it has actually been updated. sql/sql_repl.cc: No need to set pointer to the address of '\0'. sql/sql_show.cc: Put variable under the same ifdef block. sql/udf_example.c: Set null pointer flag appropriately. storage/csv/ha_tina.cc: Meaningless dereferences. storage/example/ha_example.cc: Return the error since it's available. storage/myisam/mi_locking.c: Remove unused and dead code. --- include/mysys_err.h | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'include/mysys_err.h') diff --git a/include/mysys_err.h b/include/mysys_err.h index 09e77248c17..6294b37f773 100644 --- a/include/mysys_err.h +++ b/include/mysys_err.h @@ -62,7 +62,9 @@ extern const char * NEAR globerrs[]; /* my_error_messages is here */ #define EE_UNKNOWN_COLLATION 28 #define EE_FILENOTFOUND 29 #define EE_FILE_NOT_CLOSED 30 -#define EE_ERROR_LAST 30 /* Copy last error nr */ +#define EE_CHANGE_OWNERSHIP 31 +#define EE_CHANGE_PERMISSIONS 32 +#define EE_ERROR_LAST 32 /* Copy last error nr */ /* Add error numbers before EE_ERROR_LAST and change it accordingly. */ /* exit codes for all MySQL programs */ -- cgit v1.2.1
