   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 5.      Use ext2fs_llseek instead of llseek. With recent e2fsprogs
  21         this should enable dumping big (huge) filesystems.
  22
  23 6.      Added the RSH environment variable in order to be able to
  24         use a rsh replacement like ssh when doing remote backups (and
  25         bypass the security limitations of rcmd). Now you can do remote
  26         backups without being root (or making dump setuid root).
  27
  28 7.      Modified again the way dumpdates works. For incremental dumps,
  29         we need to read dumpdates even if we are not using 'u' option.
  30         Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
  31         this should work.
  32
  33 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
  34 ===================================================================
  35
  36 1.      Removed the 'k' flag from the restore 'about' text if kerberos
  37         was not compiled in.
  38
  39 2.      Prototyped (f)setflags from e2fsprogs and corrected the calls
  40         to them (fsetflags takes a char*, setflags an open fd!).
  41
  42 3.      (f)setflags is called only if the flags aren't empty. If the
  43         file is a special file, a warning is printed, because changing
  44         flags implies opening the device. Normally, a special file
  45         should not have any flag... (Debian bug #29775, patch provided
  46         by Abhijit Dasgupta <abhijit@ans.net>).
  47
  48 4.      Made possible to dump a file system not mentioned in /etc/fstab.
  49         (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
  50
  51 5.      Changed the default behaviour to not create dumpdates
  52         unless 'u' option is specified. Removed the old "debian-patch"
  53         which provided the same thing. (Debian bug #38136, #33818).
  54
  55 6.      Removed all those dump*announce, since they were getting old...
  56
  57 7.      Added warning messages if dumpdates does not exist and
  58         when an inferior level dump does not exist (except for a level 0
  59         dump).
  60
  61 8.      Debugged the glob calls in interactive mode: restore used a
  62         dirent struct which was different from the /usr/include/dirent.h
  63         one (this used to work, is it a glibc2 change?), so none of the
  64         compat glob (which used /usr/include/dirent.h) or the system glob
  65         worked. Restore use now the system dirent (and the system
  66         DT_* constants), which are compatible with BSD ones.
  67
  68 9.      Added a configure flag (--with-dumpdatespath) to specify
  69         the location of dumpdates file. By default, it is
  70         /etc/dumpdates.
  71
  72 10.     Added the "AUTHOR" and "AVAILABILITY" sections and
  73         included the current date/version in man pages.
  74
  75 11.     Corrected the estimation of remaining time when
  76         the operator doesn't change the tapes quickly enough. This
  77         was an old bug, I thought I corrected it, and discovered
  78         that in fact it was corrected in two different places, so
  79         the results canceled each other...
  80
  81 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
  82 ===================================================================
  83
  84 1.      Integrated multiple patches from RedHat, Debian and SuSE:
  85
  86         - tweak dump/itime.c to not try to read dumpdates if the 'u' option
  87           isn't specified.
  88         - several fixes in the man pages.
  89         - update the default tape device to /dev/st0.
  90         - many updates for Linux Alpha (byte ordering, size_t etc).
  91         - buffer overruns.
  92         - use environment variable for TMPDIR (instead of /tmp).
  93         - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
  94         - workaround egcs bug (RedHat bugs #4281 and #2989).
  95         - wire $(OPT) throughout Makefile's.
  96
  97 2.      Upgrade the dump revision to 1, making possible to dump filesystems
  98         made with e2fsprogs-1.15 or newer. Nothing seems to break...
  99
 100 3.      Fix some compile warnings, prototype all functions.
 101
 102 4.      Use glibc err/glob instead of internal compatibility
 103         routines (only if available).
 104
 105 5.      Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
 106         by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
 107
 108 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
 109 ======================================================================
 110
 111 1.      Integrated the changes from FreeBSD-3.1-RELEASE
 112         (mostly bug fixes, buffer overruns, dump has now an "automatic
 113         tape length calculation" flag, dump/restore can use kerberos now
 114         (this is NOT tested), use environment variables for TAPE and
 115         RMT etc.).
 116
 117 2.      Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
 118
 119 3.      Corrected a bug in restore when using 'C' option with multi-volumes
 120         tapes (files splited accros two tapes give "size changed" errors
 121         when comparing).
 122
 123 4.      Corrected the long standing bug when dumping multiple tapes.
 124         This works for me, needs further testing.
 125
 126 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
 127 ====================================================================
 128
 129 1.      Dump now runs correctly on kernels 2.1.x
 130         Fix made by Gerald Peters <gapeters@worldnet.att.net>
 131
 132 Changes between versions 0.4b2 and 0.4b3
 133 ========================================
 134
 135 1.      Use realpath() if available
 136
 137 2.      Report statistics
 138
 139 Changes between versions 0.4b1 and 0.4b2
 140 ========================================
 141
 142 1.      Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
 143         the patch)
 144
 145 2.      Fixed restore to make it able to read FreeBSD 2.x dumps again
 146
 147 3.      Fixed configure.in to correctly handle --enable-rmt
 148
 149 Changes between versions 0.3 and 0.4b1
 150 ======================================
 151
 152 1.      Integrated the changes from 4.4BSD-Lite2
 153
 154 2.      Integrated the patches from Debian and Red Hat
 155
 156 3.      Portability changes: use the __u32, __u16, __s32, and __s16 types
 157
 158 4.      Changed dump to use the Ext2fs library to get block addresses.  This
 159         should solve the endianness problem on SparcLinux.
 160
 161 5.      Created a configure.in file (shamelessly stolen from the e2fsprogs
 162         distribution's one) to use autoconf
 163
 164 6.      Fixed a few minor bugs
 165
 166 Changes between versions 0.2e and 0.2f
 167 ======================================
 168
 169 1.      Added the creation of named pipes (fifos) in restore.
 170
 171 2.      Added the -N flag in the restore manual page.
 172
 173 3.      Added the file kernel.patch which contains the llseek() optimization
 174         patch for 1.2.x kernels.
 175
 176 4.      Fixed a bug in the restoration of symbolic links: owner and group were
 177         not restored.
 178
 179 5.      Integrated some changes from FreeBSD 2.2.
 180
 181 6.      Added a call to ftruncate() after restoring each file to restore
 182         correctly files ending by a hole.
 183
 184 Changes between versions 0.2d and 0.2e
 185 ======================================
 186
 187 1.      Fixed a bug in the "set owner/mode" process.  Every file was restored
 188         with owner = root (0) and group = root/wheel/whatever (0).
 189
 190 Changes between versions 0.2c and 0.2d
 191 ======================================
 192
 193 1.      Dump is now able to backup 2GB+ filesystems.
 194
 195 2.      Dump and restore can now be linked as static binaries.
 196
 197 Changes between versions 0.2b and 0.2c
 198 ======================================
 199
 200 1.      Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
 201
 202 Changes between versions 0.2a and 0.2b
 203 ======================================
 204
 205 1.      Really fixed the bug that I should have corrected in 0.2a.
 206
 207 2.      Enabled optimization again.
 208
 209 Changes between versions 0.2 and 0.2a
 210 =====================================
 211
 212 1.      Disabled the optimization during compilation.
 213
 214 Changes between versions 0.1 and 0.2
 215 ====================================
 216
 217 1.      Fixed a bug in fstab.c which caused a null pointer to be stored in
 218         the fs_type field (actually, I modified the file fstab.c to make it
 219         use the mntent functions).
 220
 221 2.      Dump and restore now use a 4.3 BSD compatible dump format.  Backups
 222         made by dump should be readable by the BSD restore and backups made
 223         by the BSD dump should be readable by restore.  Unfortunately, this
 224         means that the dump format has changed between version 0.1 and version
 225         0.2 :-(
 226
 227 3.      Dump is now able to backup a subtree, it is no longer limited to whole
 228         filesystems like the BSD version.
 229
 230 4.      Dump now uses ext2_llseek() so it is able to backup filesystems bigger
 231         than 2 GB.
 232
 233 Changes between versions 0.0 and 0.1
 234 ====================================
 235
 236 1.      Now create links rdump and rrestore during the `make install' step.
 237
 238 2.      Linux port specific bugs added to the manual pages
 239
 240 3.      Incorrect estimation of the number of tapes blocks fixed when doing
 241         incremental backups.
 242
 243 4.      Better ls-like format in restore in interactive mode.
