From: Laurent Papier Date: Wed, 18 May 2011 21:25:30 +0000 (+0200) Subject: Add LZO compression support in bacula-fd. X-Git-Tag: Release-7.0.0~889 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=bcfc3499e3ed90d43bef43e4a60edabecb4b236f;p=bacula%2Fbacula Add LZO compression support in bacula-fd. Add new generic compressed streams This should make easier to add additional compression scheme Rename a few define, add an element containing compression algorithm in some data structures. --- diff --git a/bacula/autoconf/acconfig.h b/bacula/autoconf/acconfig.h index de62f6c49e..d655307d64 100644 --- a/bacula/autoconf/acconfig.h +++ b/bacula/autoconf/acconfig.h @@ -114,6 +114,9 @@ /* Define if you have zlib */ #undef HAVE_LIBZ +/* Define if you have lzo lib */ +#undef HAVE_LZO + /* Define if you have libacl */ #undef HAVE_ACL diff --git a/bacula/autoconf/configure.in b/bacula/autoconf/configure.in index f7387bbd91..525a0e2a55 100644 --- a/bacula/autoconf/configure.in +++ b/bacula/autoconf/configure.in @@ -2495,6 +2495,19 @@ if test x$ZLIBS = x-lz; then fi AC_SUBST(ZLIBS) +dnl +dnl Check for lzo +dnl +AC_CHECK_HEADERS(lzo/lzoconf.h) +AC_CHECK_HEADERS(lzo/lzo1x.h) +AC_CHECK_LIB(lzo2, lzo1x_1_compress, [LZOLIBS="-llzo2"]) +have_lzo=no +if test x$LZOLIBS = x-llzo2; then + AC_DEFINE(HAVE_LZO) + have_lzo=yes +fi +AC_SUBST(LZOLIBS) + dnl dnl Check for ACL support and libraries dnl @@ -3468,6 +3481,7 @@ Configuration on `date`: TLS support: ${support_tls} Encryption support: ${support_crypto} ZLIB support: ${have_zlib} + LZO support: ${have_lzo} enable-smartalloc: ${support_smartalloc} enable-lockmgr: ${support_lockmgr} bat support: ${support_bat} diff --git a/bacula/src/ch.h b/bacula/src/ch.h new file mode 100644 index 0000000000..168cfd0be0 --- /dev/null +++ b/bacula/src/ch.h @@ -0,0 +1,58 @@ +/* + Bacula® - The Network Backup Solution + + Copyright (C) 2000-2008 Free Software Foundation Europe e.V. + + The main author of Bacula is Kern Sibbald, with contributions from + many others, a complete list can be found in the file AUTHORS. + This program is Free Software; you can redistribute it and/or + modify it under the terms of version three of the GNU Affero General Public + License as published by the Free Software Foundation and included + in the file LICENSE. + + This program 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.
