Changed the -B option of dump to limit the size of _compressed_ output per volume if compression is on. Patch contributed by Helmut Jarausch - . + . Note however that, since + it is impossible to predict the size of the compressed + data before doing the compression, the -B limit is a bit + conservative. 7. Fixed a bug in reading the operator typed file/tape path for the next volume in restore. diff --git a/dump/dump.h b/dump/dump.h index 1f4ab9e..dacfee1 100644 --- a/dump/dump.h +++ b/dump/dump.h @@ -5,7 +5,7 @@ * Stelian Pop , 1999-2000 * Stelian Pop - Alcôve , 2000 * - * $Id: dump.h,v 1.28 2001/07/19 09:49:35 stelian Exp $ + * $Id: dump.h,v 1.29 2001/07/20 11:02:45 stelian Exp $ */ /*- @@ -86,7 +86,6 @@ int density; /* density in 0.1" units */ long tapesize; /* estimated tape size, blocks */ long tsize; /* tape size in 0.1" units */ long asize; /* number of 0.1" units written on current tape */ -unsigned long csize; /* number of compressed bytes written on current tape */ int etapes; /* estimated number of tapes */ int nonodump; /* if set, do not honor UF_NODUMP user flags */ int unlimited; /* if set, write to end of medium */ diff --git a/dump/tape.c b/dump/tape.c index f048a78..5e79fd2 100644 --- a/dump/tape.c +++ b/dump/tape.c @@ -41,7 +41,7 @@ #ifndef lint static const char rcsid[] = - "$Id: tape.c,v 1.52 2001/07/20 09:01:46 stelian Exp $"; + "$Id: tape.c,v 1.53 2001/07/20 11:02:45 stelian Exp $"; #endif /* not lint */ #include @@ -443,12 +443,11 @@ flushtape(void) nextblock = slp->tblock; trecno = 0; asize += tenths + returned.clen / density; - csize += returned.clen; blockswritten += ntrec; blocksthisvol += ntrec; if (!pipeout && !unlimited) { if (blocksperfile) { - if ( compressed ? csize + writesize >= blocksperfile * 1024 + if ( compressed ?
