   3 Changes between versions 0.4b7 and 0.4b8 (released ???????????????)
   4 ===================================================================
   5
   6 1.      Put dump sources under CVS, added Id tags in all files so
   7         one can use 'ident' on binary files.
   8
   9 2.      Added the dump/restore version in the usage text so one can
  10         easily verify the version he is using.
  11
  12 3.      Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
  13         a va_start/va_end problem on linux-ppc (always call va_start
  14         va_end in pairs each time we use a vararg function).
  15
  16 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
  17 ===================================================================
  18
  19 1.      Removed the 'k' flag from the restore 'about' text if kerberos
  20         was not compiled in.
  21
  22 2.      Prototyped (f)setflags from e2fsprogs and corrected the calls
  23         to them (fsetflags takes a char*, setflags an open fd!).
  24
  25 3.      (f)setflags is called only if the flags aren't empty. If the
  26         file is a special file, a warning is printed, because changing
  27         flags implies opening the device. Normally, a special file
  28         should not have any flag... (Debian bug #29775, patch provided
  29         by Abhijit Dasgupta <abhijit@ans.net>).
  30
  31 4.      Made possible to dump a file system not mentioned in /etc/fstab.
  32         (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
  33
  34 5.      Changed the default behaviour to not create dumpdates
  35         unless 'u' option is specified. Removed the old "debian-patch"
  36         which provided the same thing. (Debian bug #38136, #33818).
  37
  38 6.      Removed all those dump*announce, since they were getting old...
  39
  40 7.      Added warning messages if dumpdates does not exist and
  41         when an inferior level dump does not exist (except for a level 0
  42         dump).
  43
  44 8.      Debugged the glob calls in interactive mode: restore used a
  45         dirent struct which was different from the /usr/include/dirent.h
  46         one (this used to work, is it a glibc2 change?), so none of the
  47         compat glob (which used /usr/include/dirent.h) or the system glob
  48         worked. Restore use now the system dirent (and the system
  49         DT_* constants), which are compatible with BSD ones.
  50
  51 9.      Added a configure flag (--with-dumpdatespath) to specify
  52         the location of dumpdates file. By default, it is
  53         /etc/dumpdates.
  54
  55 10.     Added the "AUTHOR" and "AVAILABILITY" sections and
  56         included the current date/version in man pages.
  57
  58 11.     Corrected the estimation of remaining time when
  59         the operator doesn't change the tapes quickly enough. This
  60         was an old bug, I thought I corrected it, and discovered
  61         that in fact it was corrected in two different places, so
  62         the results canceled each other...
  63
  64 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
  65 ===================================================================
  66
  67 1.      Integrated multiple patches from RedHat, Debian and SuSE:
  68
  69         - tweak dump/itime.c to not try to read dumpdates if the 'u' option
  70           isn't specified.
  71         - several fixes in the man pages.
  72         - update the default tape device to /dev/st0.
  73         - many updates for Linux Alpha (byte ordering, size_t etc).
  74         - buffer overruns.
  75         - use environment variable for TMPDIR (instead of /tmp).
  76         - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
  77         - workaround egcs bug (RedHat bugs #4281 and #2989).
  78         - wire $(OPT) throughout Makefile's.
  79
  80 2.      Upgrade the dump revision to 1, making possible to dump filesystems
  81         made with e2fsprogs-1.15 or newer. Nothing seems to break...
  82
  83 3.      Fix some compile warnings, prototype all functions.
  84
  85 4.      Use glibc err/glob instead of internal compatibility
  86         routines (only if available).
  87
  88 5.      Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
  89         by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
  90
  91 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
  92 ======================================================================
  93
  94 1.      Integrated the changes from FreeBSD-3.1-RELEASE
  95         (mostly bug fixes, buffer overruns, dump has now an "automatic
  96         tape length calculation" flag, dump/restore can use kerberos now
  97         (this is NOT tested), use environment variables for TAPE and
  98         RMT etc.).
  99
 100 2.      Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
 101
 102 3.      Corrected a bug in restore when using 'C' option with multi-volumes
 103         tapes (files splited accros two tapes give "size changed" errors
 104         when comparing).
 105
 106 4.      Corrected the long standing bug when dumping multiple tapes.
 107         This works for me, needs further testing.
 108
 109 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
 110 ====================================================================
 111
 112 1.      Dump now runs correctly on kernels 2.1.x
 113         Fix made by Gerald Peters <gapeters@worldnet.att.net>
 114
 115 Changes between versions 0.4b2 and 0.4b3
 116 ========================================
 117
 118 1.      Use realpath() if available
 119
 120 2.      Report statistics
 121
 122 Changes between versions 0.4b1 and 0.4b2
 123 ========================================
 124
 125 1.      Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
 126         the patch)
 127
 128 2.      Fixed restore to make it able to read FreeBSD 2.x dumps again
 129
 130 3.      Fixed configure.in to correctly handle --enable-rmt
 131
 132 Changes between versions 0.3 and 0.4b1
 133 ======================================
 134
 135 1.      Integrated the changes from 4.4BSD-Lite2
 136
 137 2.      Integrated the patches from Debian and Red Hat
 138
 139 3.      Portability changes: use the __u32, __u16, __s32, and __s16 types
 140
 141 4.      Changed dump to use the Ext2fs library to get block addresses.  This
 142         should solve the endianness problem on SparcLinux.
 143
 144 5.      Created a configure.in file (shamelessly stolen from the e2fsprogs
 145         distribution's one) to use autoconf
 146
 147 6.      Fixed a few minor bugs
 148
 149 Changes between versions 0.2e and 0.2f
 150 ======================================
 151
 152 1.      Added the creation of named pipes (fifos) in restore.
 153
 154 2.      Added the -N flag in the restore manual page.
 155
 156 3.      Added the file kernel.patch which contains the llseek() optimization
 157         patch for 1.2.x kernels.
 158
 159 4.      Fixed a bug in the restoration of symbolic links: owner and group were
 160         not restored.
 161
 162 5.      Integrated some changes from FreeBSD 2.2.
 163
 164 6.      Added a call to ftruncate() after restoring each file to restore
 165         correctly files ending by a hole.
 166
 167 Changes between versions 0.2d and 0.2e
 168 ======================================
 169
 170 1.      Fixed a bug in the "set owner/mode" process.  Every file was restored
 171         with owner = root (0) and group = root/wheel/whatever (0).
 172
 173 Changes between versions 0.2c and 0.2d
 174 ======================================
 175
 176 1.      Dump is now able to backup 2GB+ filesystems.
 177
 178 2.      Dump and restore can now be linked as static binaries.
 179
 180 Changes between versions 0.2b and 0.2c
 181 ======================================
 182
 183 1.      Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
 184
 185 Changes between versions 0.2a and 0.2b
 186 ======================================
 187
 188 1.      Really fixed the bug that I should have corrected in 0.2a.
 189
 190 2.      Enabled optimization again.
 191
 192 Changes between versions 0.2 and 0.2a
 193 =====================================
 194
 195 1.      Disabled the optimization during compilation.
 196
 197 Changes between versions 0.1 and 0.2
 198 ====================================
 199
 200 1.      Fixed a bug in fstab.c which caused a null pointer to be stored in
 201         the fs_type field (actually, I modified the file fstab.c to make it
 202         use the mntent functions).
 203
 204 2.      Dump and restore now use a 4.3 BSD compatible dump format.  Backups
 205         made by dump should be readable by the BSD restore and backups made
 206         by the BSD dump should be readable by restore.  Unfortunately, this
 207         means that the dump format has changed between version 0.1 and version
 208         0.2 :-(
 209
 210 3.      Dump is now able to backup a subtree, it is no longer limited to whole
 211         filesystems like the BSD version.
 212
 213 4.      Dump now uses ext2_llseek() so it is able to backup filesystems bigger
 214         than 2 GB.
 215
 216 Changes between versions 0.0 and 0.1
 217 ====================================
 218
 219 1.      Now create links rdump and rrestore during the `make install' step.
 220
 221 2.      Linux port specific bugs added to the manual pages
 222
 223 3.      Incorrect estimation of the number of tapes blocks fixed when doing
 224         incremental backups.
 225
 226 4.      Better ls-like format in restore in interactive mode.
