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