From: Adam Dickmeiss Date: Fri, 16 Apr 2010 13:04:18 +0000 (+0200) Subject: yaz_log: Log level tid logs thread ID X-Git-Tag: v4.0.4~20 X-Git-Url: http://git.indexdata.com/?p=yaz-moved-to-github.git;a=commitdiff_plain;h=6f2f82e34ee173a0626432b57ebcbb8375e83a68 yaz_log: Log level tid logs thread ID Add new utility yaz_thread_id_cstr to return human-readable ID of current thread. At this stage pthread_self is used. This can be misleading because pthread_t (pointers presumably) are reused between thread creations. --- diff --git a/include/yaz/Makefile.am b/include/yaz/Makefile.am index c2ec308..843dd22 100644 --- a/include/yaz/Makefile.am +++ b/include/yaz/Makefile.am @@ -20,7 +20,7 @@ pkginclude_HEADERS= backend.h ccl.h ccl_xml.h cql.h rpn2cql.h comstack.h \ z-univ.h z-oclcui.h zes-expi.h zes-exps.h zes-order.h zes-pquery.h \ zes-psched.h zes-admin.h zes-pset.h zes-update.h zes-update0.h \ zoom.h z-charneg.h charneg.h soap.h srw.h zgdu.h matchstr.h json.h \ - file_glob.h dirent.h + file_glob.h dirent.h thread_id.h EXTRA_DIST = yaz-version.h.in diff --git a/include/yaz/log.h b/include/yaz/log.h index b7cfad6..ddcbb85 100644 --- a/include/yaz/log.h +++ b/include/yaz/log.h @@ -48,6 +48,8 @@ YAZ_BEGIN_CDECL #define YLOG_LOG 0x00000008 /** \brief log level: append system error message */ #define YLOG_ERRNO 0x00000010 +/** \brief log level: append thread Id */ +#define YLOG_TID 0x00000020 /** \brief log level: application */ #define YLOG_APP 0x00000040 /** \brief log level: malloc debug */ diff --git a/include/yaz/thread_id.h b/include/yaz/thread_id.h new file mode 100644 index 0000000..608ed14 --- /dev/null +++ b/include/yaz/thread_id.h @@ -0,0 +1,59 @@ +/* This file is part of the YAZ toolkit. + * Copyright (C) 1995-2010 Index Data. + * All rights reserved. + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions are met: + * + * * Redistributions of source code must retain the above copyright + * notice, this list of conditions and the following disclaimer. + * * Redistributions in binary form must reproduce the above copyright + * notice, this list of conditions and the following disclaimer in the + * documentation and/or other materials provided with the distribution. + * * Neither the name of Index Data nor the names of its contributors + * may be used to endorse or promote products derived from this + * software without specific prior written permission. + * + * THIS SOFTWARE IS PROVIDED BY THE REGENTS AND CONTRIBUTORS ``AS IS'' AND ANY + * EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED + * WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE + * DISCLAIMED.
