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