   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 4.      Added again the DT_* constants because old libc does not
  17         contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
  18         for submitting the bug report.
  19
  20 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
  21 ===================================================================
  22
  23 1.      Removed the 'k' flag from the restore 'about' text if kerberos
  24         was not compiled in.
  25
  26 2.      Prototyped (f)setflags from e2fsprogs and corrected the calls
  27         to them (fsetflags takes a char*, setflags an open fd!).
  28
  29 3.      (f)setflags is called only if the flags aren't empty. If the
  30         file is a special file, a warning is printed, because changing
  31         flags implies opening the device. Normally, a special file
  32         should not have any flag... (Debian bug #29775, patch provided
  33         by Abhijit Dasgupta <abhijit@ans.net>).
  34
  35 4.      Made possible to dump a file system not mentioned in /etc/fstab.
  36         (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
  37
  38 5.      Changed the default behaviour to not create dumpdates
  39         unless 'u' option is specified. Removed the old "debian-patch"
  40         which provided the same thing. (Debian bug #38136, #33818).
  41
  42 6.      Removed all those dump*announce, since they were getting old...
  43
  44 7.      Added warning messages if dumpdates does not exist and
  45         when an inferior level dump does not exist (except for a level 0
  46         dump).
  47
  48 8.      Debugged the glob calls in interactive mode: restore used a
  49         dirent struct which was different from the /usr/include/dirent.h
  50         one (this used to work, is it a glibc2 change?), so none of the
  51         compat glob (which used /usr/include/dirent.h) or the system glob
  52         worked. Restore use now the system dirent (and the system
  53         DT_* constants), which are compatible with BSD ones.
  54
  55 9.      Added a configure flag (--with-dumpdatespath) to specify
  56         the location of dumpdates file. By default, it is
  57         /etc/dumpdates.
  58
  59 10.     Added the "AUTHOR" and "AVAILABILITY" sections and
  60         included the current date/version in man pages.
  61
  62 11.     Corrected the estimation of remaining time when
  63         the operator doesn't change the tapes quickly enough. This
  64         was an old bug, I thought I corrected it, and discovered
  65         that in fact it was corrected in two different places, so
  66         the results canceled each other...
  67
  68 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
  69 ===================================================================
  70
  71 1.      Integrated multiple patches from RedHat, Debian and SuSE:
  72
  73         - tweak dump/itime.c to not try to read dumpdates if the 'u' option
  74           isn't specified.
  75         - several fixes in the man pages.
  76         - update the default tape device to /dev/st0.
  77         - many updates for Linux Alpha (byte ordering, size_t etc).
  78         - buffer overruns.
  79         - use environment variable for TMPDIR (instead of /tmp).
  80         - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
  81         - workaround egcs bug (RedHat bugs #4281 and #2989).
  82         - wire $(OPT) throughout Makefile's.
  83
  84 2.      Upgrade the dump revision to 1, making possible to dump filesystems
  85         made with e2fsprogs-1.15 or newer. Nothing seems to break...
  86
  87 3.      Fix some compile warnings, prototype all functions.
  88
  89 4.      Use glibc err/glob instead of internal compatibility
  90         routines (only if available).
  91
  92 5.      Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
  93         by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
  94
  95 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
  96 ======================================================================
  97
  98 1.      Integrated the changes from FreeBSD-3.1-RELEASE
  99         (mostly bug fixes, buffer overruns, dump has now an "automatic
 100         tape length calculation" flag, dump/restore can use kerberos now
 101         (this is NOT tested), use environment variables for TAPE and
 102         RMT etc.).
 103
 104 2.      Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
 105
 106 3.      Corrected a bug in restore when using 'C' option with multi-volumes
 107         tapes (files splited accros two tapes give "size changed" errors
 108         when comparing).
 109
 110 4.      Corrected the long standing bug when dumping multiple tapes.
 111         This works for me, needs further testing.
 112
 113 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
 114 ====================================================================
 115
 116 1.      Dump now runs correctly on kernels 2.1.x
 117         Fix made by Gerald Peters <gapeters@worldnet.att.net>
 118
 119 Changes between versions 0.4b2 and 0.4b3
 120 ========================================
 121
 122 1.      Use realpath() if available
 123
 124 2.      Report statistics
 125
 126 Changes between versions 0.4b1 and 0.4b2
 127 ========================================
 128
 129 1.      Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
 130         the patch)
 131
 132 2.      Fixed restore to make it able to read FreeBSD 2.x dumps again
 133
 134 3.      Fixed configure.in to correctly handle --enable-rmt
 135
 136 Changes between versions 0.3 and 0.4b1
 137 ======================================
 138
 139 1.      Integrated the changes from 4.4BSD-Lite2
 140
 141 2.      Integrated the patches from Debian and Red Hat
 142
 143 3.      Portability changes: use the __u32, __u16, __s32, and __s16 types
 144
 145 4.      Changed dump to use the Ext2fs library to get block addresses.  This
 146         should solve the endianness problem on SparcLinux.
 147
 148 5.      Created a configure.in file (shamelessly stolen from the e2fsprogs
 149         distribution's one) to use autoconf
 150
 151 6.      Fixed a few minor bugs
 152
 153 Changes between versions 0.2e and 0.2f
 154 ======================================
 155
 156 1.      Added the creation of named pipes (fifos) in restore.
 157
 158 2.      Added the -N flag in the restore manual page.
 159
 160 3.      Added the file kernel.patch which contains the llseek() optimization
 161         patch for 1.2.x kernels.
 162
 163 4.      Fixed a bug in the restoration of symbolic links: owner and group were
 164         not restored.
 165
 166 5.      Integrated some changes from FreeBSD 2.2.
 167
 168 6.      Added a call to ftruncate() after restoring each file to restore
 169         correctly files ending by a hole.
 170
 171 Changes between versions 0.2d and 0.2e
 172 ======================================
 173
 174 1.      Fixed a bug in the "set owner/mode" process.  Every file was restored
 175         with owner = root (0) and group = root/wheel/whatever (0).
 176
 177 Changes between versions 0.2c and 0.2d
 178 ======================================
 179
 180 1.      Dump is now able to backup 2GB+ filesystems.
 181
 182 2.      Dump and restore can now be linked as static binaries.
 183
 184 Changes between versions 0.2b and 0.2c
 185 ======================================
 186
 187 1.      Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
 188
 189 Changes between versions 0.2a and 0.2b
 190 ======================================
 191
 192 1.      Really fixed the bug that I should have corrected in 0.2a.
 193
 194 2.      Enabled optimization again.
 195
 196 Changes between versions 0.2 and 0.2a
 197 =====================================
 198
 199 1.      Disabled the optimization during compilation.
 200
 201 Changes between versions 0.1 and 0.2
 202 ====================================
 203
 204 1.      Fixed a bug in fstab.c which caused a null pointer to be stored in
 205         the fs_type field (actually, I modified the file fstab.c to make it
 206         use the mntent functions).
 207
 208 2.      Dump and restore now use a 4.3 BSD compatible dump format.  Backups
 209         made by dump should be readable by the BSD restore and backups made
 210         by the BSD dump should be readable by restore.  Unfortunately, this
 211         means that the dump format has changed between version 0.1 and version
 212         0.2 :-(
 213
 214 3.      Dump is now able to backup a subtree, it is no longer limited to whole
 215         filesystems like the BSD version.
 216
 217 4.      Dump now uses ext2_llseek() so it is able to backup filesystems bigger
 218         than 2 GB.
 219
 220 Changes between versions 0.0 and 0.1
 221 ====================================
 222
 223 1.      Now create links rdump and rrestore during the `make install' step.
 224
 225 2.      Linux port specific bugs added to the manual pages
 226
 227 3.      Incorrect estimation of the number of tapes blocks fixed when doing
 228         incremental backups.
 229
 230 4.      Better ls-like format in restore in interactive mode.
