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