From: Marcus Brinkmann Date: Wed, 8 May 2002 04:04:12 +0000 (+0000) Subject: 2002-05-08 Marcus Brinkmann X-Git-Tag: gpgme-0-3-7~29 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=51e6cf89edbcdb4dd39e83f467da695ebdecb228;p=gpgme.git 2002-05-08 Marcus Brinkmann * debug.h: New file. * Makefile.am (libgpgme_la_SOURCES): Add debug.h. * util.h: Removed all prototypes and declarations related to debugging. Include "debug.h". * debug.c (debug_level): Comment variable and remove superfluous zero initializer. (errfp): Likewise. (_gpgme_debug_enabled): Function removed. (struct debug_control_s): Definition removed. (_gpgme_debug_level): Function removed. (_gpgme_debug_begin): Rewritten to use vasprintf. Accept a pritnf-style format specification and a variable number of arguments. (_gpgme_debug_add): Rewritten using vasprintf. Expect that format starts out with "%s" for simplicity. (_gpgme_debug_end): Rewritten using vasprintf. Do not accept a TEXT argument anymore. * posix-io.c (_gpgme_io_select): Use new level argument for DEBUG_BEGIN instead explicit if construct. * debug.c (debug_init): Remove superfluous zero initializer, remove volatile flag of INITIALIZED. Do not use the double-checked locking algorithm, it is fundamentally flawed and will empty your fridge (on a more serious note, despite the volatile flag it doesn't give you the guarantee you would expect, for example on a DEC Alpha or an SMP machine. The volatile only serializes accesses to the volatile variable, but not to the other variables). --- diff --git a/gpgme/debug.h b/gpgme/debug.h new file mode 100644 index 0000000..bdeaebc --- /dev/null +++ b/gpgme/debug.h @@ -0,0 +1,110 @@ +/* debug.h - interface to debugging functions + * Copyright (C) 2002 g10 Code GmbH + * + * This file is part of GPGME. + * + * GPGME is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * GPGME is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
