   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 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
  26 ===================================================================
  27
  28 1.      Removed the 'k' flag from the restore 'about' text if kerberos
  29         was not compiled in.
  30
  31 2.      Prototyped (f)setflags from e2fsprogs and corrected the calls
  32         to them (fsetflags takes a char*, setflags an open fd!).
  33
  34 3.      (f)setflags is called only if the flags aren't empty. If the
  35         file is a special file, a warning is printed, because changing
  36         flags implies opening the device. Normally, a special file
  37         should not have any flag... (Debian bug #29775, patch provided
  38         by Abhijit Dasgupta <abhijit@ans.net>).
  39
  40 4.      Made possible to dump a file system not mentioned in /etc/fstab.
  41         (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
  42
  43 5.      Changed the default behaviour to not create dumpdates
  44         unless 'u' option is specified. Removed the old "debian-patch"
  45         which provided the same thing. (Debian bug #38136, #33818).
  46
  47 6.      Removed all those dump*announce, since they were getting old...
  48
  49 7.      Added warning messages if dumpdates does not exist and
  50         when an inferior level dump does not exist (except for a level 0
  51         dump).
  52
  53 8.      Debugged the glob calls in interactive mode: restore used a
  54         dirent struct which was different from the /usr/include/dirent.h
  55         one (this used to work, is it a glibc2 change?), so none of the
  56         compat glob (which used /usr/include/dirent.h) or the system glob
  57         worked. Restore use now the system dirent (and the system
  58         DT_* constants), which are compatible with BSD ones.
  59
  60 9.      Added a configure flag (--with-dumpdatespath) to specify
  61         the location of dumpdates file. By default, it is
  62         /etc/dumpdates.
  63
  64 10.     Added the "AUTHOR" and "AVAILABILITY" sections and
  65         included the current date/version in man pages.
  66
  67 11.     Corrected the estimation of remaining time when
  68         the operator doesn't change the tapes quickly enough. This
  69         was an old bug, I thought I corrected it, and discovered
  70         that in fact it was corrected in two different places, so
  71         the results canceled each other...
  72
  73 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
  74 ===================================================================
  75
  76 1.      Integrated multiple patches from RedHat, Debian and SuSE:
  77
  78         - tweak dump/itime.c to not try to read dumpdates if the 'u' option
  79           isn't specified.
  80         - several fixes in the man pages.
  81         - update the default tape device to /dev/st0.
  82         - many updates for Linux Alpha (byte ordering, size_t etc).
  83         - buffer overruns.
  84         - use environment variable for TMPDIR (instead of /tmp).
  85         - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
  86         - workaround egcs bug (RedHat bugs #4281 and #2989).
  87         - wire $(OPT) throughout Makefile's.
  88
  89 2.      Upgrade the dump revision to 1, making possible to dump filesystems
  90         made with e2fsprogs-1.15 or newer. Nothing seems to break...
  91
  92 3.      Fix some compile warnings, prototype all functions.
  93
  94 4.      Use glibc err/glob instead of internal compatibility
  95         routines (only if available).
  96
  97 5.      Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
  98         by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
  99
 100 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
 101 ======================================================================
 102
 103 1.      Integrated the changes from FreeBSD-3.1-RELEASE
 104         (mostly bug fixes, buffer overruns, dump has now an "automatic
 105         tape length calculation" flag, dump/restore can use kerberos now
 106         (this is NOT tested), use environment variables for TAPE and
 107         RMT etc.).
 108
 109 2.      Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
 110
 111 3.      Corrected a bug in restore when using 'C' option with multi-volumes
 112         tapes (files splited accros two tapes give "size changed" errors
 113         when comparing).
 114
 115 4.      Corrected the long standing bug when dumping multiple tapes.
 116         This works for me, needs further testing.
 117
 118 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
 119 ====================================================================
 120
 121 1.      Dump now runs correctly on kernels 2.1.x
 122         Fix made by Gerald Peters <gapeters@worldnet.att.net>
 123
 124 Changes between versions 0.4b2 and 0.4b3
 125 ========================================
 126
 127 1.      Use realpath() if available
 128
 129 2.      Report statistics
 130
 131 Changes between versions 0.4b1 and 0.4b2
 132 ========================================
 133
 134 1.      Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
 135         the patch)
 136
 137 2.      Fixed restore to make it able to read FreeBSD 2.x dumps again
 138
 139 3.      Fixed configure.in to correctly handle --enable-rmt
 140
 141 Changes between versions 0.3 and 0.4b1
 142 ======================================
 143
 144 1.      Integrated the changes from 4.4BSD-Lite2
 145
 146 2.      Integrated the patches from Debian and Red Hat
 147
 148 3.      Portability changes: use the __u32, __u16, __s32, and __s16 types
 149
 150 4.      Changed dump to use the Ext2fs library to get block addresses.  This
 151         should solve the endianness problem on SparcLinux.
 152
 153 5.      Created a configure.in file (shamelessly stolen from the e2fsprogs
 154         distribution's one) to use autoconf
 155
 156 6.      Fixed a few minor bugs
 157
 158 Changes between versions 0.2e and 0.2f
 159 ======================================
 160
 161 1.      Added the creation of named pipes (fifos) in restore.
 162
 163 2.      Added the -N flag in the restore manual page.
 164
 165 3.      Added the file kernel.patch which contains the llseek() optimization
 166         patch for 1.2.x kernels.
 167
 168 4.      Fixed a bug in the restoration of symbolic links: owner and group were
 169         not restored.
 170
 171 5.      Integrated some changes from FreeBSD 2.2.
 172
 173 6.      Added a call to ftruncate() after restoring each file to restore
 174         correctly files ending by a hole.
 175
 176 Changes between versions 0.2d and 0.2e
 177 ======================================
 178
 179 1.      Fixed a bug in the "set owner/mode" process.  Every file was restored
 180         with owner = root (0) and group = root/wheel/whatever (0).
 181
 182 Changes between versions 0.2c and 0.2d
 183 ======================================
 184
 185 1.      Dump is now able to backup 2GB+ filesystems.
 186
 187 2.      Dump and restore can now be linked as static binaries.
 188
 189 Changes between versions 0.2b and 0.2c
 190 ======================================
 191
 192 1.      Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
 193
 194 Changes between versions 0.2a and 0.2b
 195 ======================================
 196
 197 1.      Really fixed the bug that I should have corrected in 0.2a.
 198
 199 2.      Enabled optimization again.
 200
 201 Changes between versions 0.2 and 0.2a
 202 =====================================
 203
 204 1.      Disabled the optimization during compilation.
 205
 206 Changes between versions 0.1 and 0.2
 207 ====================================
 208
 209 1.      Fixed a bug in fstab.c which caused a null pointer to be stored in
 210         the fs_type field (actually, I modified the file fstab.c to make it
 211         use the mntent functions).
 212
 213 2.      Dump and restore now use a 4.3 BSD compatible dump format.  Backups
 214         made by dump should be readable by the BSD restore and backups made
 215         by the BSD dump should be readable by restore.  Unfortunately, this
 216         means that the dump format has changed between version 0.1 and version
 217         0.2 :-(
 218
 219 3.      Dump is now able to backup a subtree, it is no longer limited to whole
 220         filesystems like the BSD version.
 221
 222 4.      Dump now uses ext2_llseek() so it is able to backup filesystems bigger
 223         than 2 GB.
 224
 225 Changes between versions 0.0 and 0.1
 226 ====================================
 227
 228 1.      Now create links rdump and rrestore during the `make install' step.
 229
 230 2.      Linux port specific bugs added to the manual pages
 231
 232 3.      Incorrect estimation of the number of tapes blocks fixed when doing
 233         incremental backups.
 234
 235 4.      Better ls-like format in restore in interactive mode.
