   3 Changes between versions 0.4b10 and 0.4b11 (released ????????????????)
   4 ======================================================================
   5
   6 1.      Added a '--enable-kerberos' to configure.
   7
   8 2.      Added a 'S' option to dump which determines the amount of space
   9         that is needed to perform the dump without actually doint it, similar
  10         to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
  11         <cermak@ahab.rutgers.edu>.
  12
  13 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
  14 ======================================================================
  15
  16 1.      Make configure test if the system glob routines support
  17         extended syntax (ALTDIRFUNC). If not, use the internal glob
  18         routines instead of system ones. Thanks to Bernhard Sadlowski
  19         <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
  20         and helping me resolve this and other minor libc5 compiling
  21         glitches.
  22
  23 2.      Fix a problem when dumping a ext2fs with the 'filetype'
  24         feature enabled. Thanks to Patrick J. LoPresti
  25         <patl@cag.lcs.mit.edu> for reporting the bug and to
  26         Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
  27
  28 3.      Made the nodump flag work on directories. A directory which
  29         has the nodump flag gets never dumped, regardless of its
  30         contents.
  31
  32 4.      Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
  33         which allows dump on an active ext3 filesystem. However, this
  34         is a "quick and dirty" patch which enables backup of an ext3
  35         filesystem through the ext2 compatibility (by ignoring the
  36         NEEDS_RECOVERY bit). The journal file is not recognized and
  37         it is dumped (it should not).
  38
  39 5.      Test the superblock compatibility flags when dumping, in order
  40         to be sure that we know how to deal with specific features.
  41
  42 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
  43 ====================================================================
  44
  45 1.      Use lchown instead of chown, fixing a possible security problem
  46         when restoring symlinks (a malicious user could use this
  47         to deliberately corrupt the ownership of important system files).
  48         Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
  49         this and providing the patch.
  50
  51 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
  52 ====================================================================
  53
  54 1.      Put dump sources under CVS, added Id tags in all files so
  55         one can use 'ident' on binary files.
  56
  57 2.      Added the dump/restore version in the usage text so one can
  58         easily verify the version he is using.
  59
  60 3.      Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
  61         a va_start/va_end problem on linux-ppc (always call va_start
  62         va_end in pairs each time we use a vararg function).
  63
  64 4.      Added again the DT_* constants because old libc does not
  65         contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
  66         for submitting the bug report.
  67
  68 5.      Use ext2fs_llseek instead of llseek. With recent e2fsprogs
  69         this should enable dumping big (huge) filesystems.
  70
  71 6.      Added the RSH environment variable in order to be able to
  72         use a rsh replacement like ssh when doing remote backups (and
  73         bypass the security limitations of rcmd). Now you can do remote
  74         backups without being root (or making dump setuid root).
  75
  76 7.      Modified again the way dumpdates works. For incremental dumps,
  77         we need to read dumpdates even if we are not using 'u' option.
  78         Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
  79         this should work.
  80
  81 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
  82 ===================================================================
  83
  84 1.      Removed the 'k' flag from the restore 'about' text if kerberos
  85         was not compiled in.
  86
  87 2.      Prototyped (f)setflags from e2fsprogs and corrected the calls
  88         to them (fsetflags takes a char*, setflags an open fd!).
  89
  90 3.      (f)setflags is called only if the flags aren't empty. If the
  91         file is a special file, a warning is printed, because changing
  92         flags implies opening the device. Normally, a special file
  93         should not have any flag... (Debian bug #29775, patch provided
  94         by Abhijit Dasgupta <abhijit@ans.net>).
  95
  96 4.      Made possible to dump a file system not mentioned in /etc/fstab.
  97         (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
  98
  99 5.      Changed the default behaviour to not create dumpdates
 100         unless 'u' option is specified. Removed the old "debian-patch"
 101         which provided the same thing. (Debian bug #38136, #33818).
 102
 103 6.      Removed all those dump*announce, since they were getting old...
 104
 105 7.      Added warning messages if dumpdates does not exist and
 106         when an inferior level dump does not exist (except for a level 0
 107         dump).
 108
 109 8.      Debugged the glob calls in interactive mode: restore used a
 110         dirent struct which was different from the /usr/include/dirent.h
 111         one (this used to work, is it a glibc2 change?), so none of the
 112         compat glob (which used /usr/include/dirent.h) or the system glob
 113         worked. Restore use now the system dirent (and the system
 114         DT_* constants), which are compatible with BSD ones.
 115
 116 9.      Added a configure flag (--with-dumpdatespath) to specify
 117         the location of dumpdates file. By default, it is
 118         /etc/dumpdates.
 119
 120 10.     Added the "AUTHOR" and "AVAILABILITY" sections and
 121         included the current date/version in man pages.
 122
 123 11.     Corrected the estimation of remaining time when
 124         the operator doesn't change the tapes quickly enough. This
 125         was an old bug, I thought I corrected it, and discovered
 126         that in fact it was corrected in two different places, so
 127         the results canceled each other...
 128
 129 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
 130 ===================================================================
 131
 132 1.      Integrated multiple patches from RedHat, Debian and SuSE:
 133
 134         - tweak dump/itime.c to not try to read dumpdates if the 'u' option
 135           isn't specified.
 136         - several fixes in the man pages.
 137         - update the default tape device to /dev/st0.
 138         - many updates for Linux Alpha (byte ordering, size_t etc).
 139         - buffer overruns.
 140         - use environment variable for TMPDIR (instead of /tmp).
 141         - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
 142         - workaround egcs bug (RedHat bugs #4281 and #2989).
 143         - wire $(OPT) throughout Makefile's.
 144
 145 2.      Upgrade the dump revision to 1, making possible to dump filesystems
 146         made with e2fsprogs-1.15 or newer. Nothing seems to break...
 147
 148 3.      Fix some compile warnings, prototype all functions.
 149
 150 4.      Use glibc err/glob instead of internal compatibility
 151         routines (only if available).
 152
 153 5.      Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
 154         by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
 155
 156 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
 157 ======================================================================
 158
 159 1.      Integrated the changes from FreeBSD-3.1-RELEASE
 160         (mostly bug fixes, buffer overruns, dump has now an "automatic
 161         tape length calculation" flag, dump/restore can use kerberos now
 162         (this is NOT tested), use environment variables for TAPE and
 163         RMT etc.).
 164
 165 2.      Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
 166
 167 3.      Corrected a bug in restore when using 'C' option with multi-volumes
 168         tapes (files splited accros two tapes give "size changed" errors
 169         when comparing).
 170
 171 4.      Corrected the long standing bug when dumping multiple tapes.
 172         This works for me, needs further testing.
 173
 174 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
 175 ====================================================================
 176
 177 1.      Dump now runs correctly on kernels 2.1.x
 178         Fix made by Gerald Peters <gapeters@worldnet.att.net>
 179
 180 Changes between versions 0.4b2 and 0.4b3
 181 ========================================
 182
 183 1.      Use realpath() if available
 184
 185 2.      Report statistics
 186
 187 Changes between versions 0.4b1 and 0.4b2
 188 ========================================
 189
 190 1.      Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
 191         the patch)
 192
 193 2.      Fixed restore to make it able to read FreeBSD 2.x dumps again
 194
 195 3.      Fixed configure.in to correctly handle --enable-rmt
 196
 197 Changes between versions 0.3 and 0.4b1
 198 ======================================
 199
 200 1.      Integrated the changes from 4.4BSD-Lite2
 201
 202 2.      Integrated the patches from Debian and Red Hat
 203
 204 3.      Portability changes: use the __u32, __u16, __s32, and __s16 types
 205
 206 4.      Changed dump to use the Ext2fs library to get block addresses.  This
 207         should solve the endianness problem on SparcLinux.
 208
 209 5.      Created a configure.in file (shamelessly stolen from the e2fsprogs
 210         distribution's one) to use autoconf
 211
 212 6.      Fixed a few minor bugs
 213
 214 Changes between versions 0.2e and 0.2f
 215 ======================================
 216
 217 1.      Added the creation of named pipes (fifos) in restore.
 218
 219 2.      Added the -N flag in the restore manual page.
 220
 221 3.      Added the file kernel.patch which contains the llseek() optimization
 222         patch for 1.2.x kernels.
 223
 224 4.      Fixed a bug in the restoration of symbolic links: owner and group were
 225         not restored.
 226
 227 5.      Integrated some changes from FreeBSD 2.2.
 228
 229 6.      Added a call to ftruncate() after restoring each file to restore
 230         correctly files ending by a hole.
 231
 232 Changes between versions 0.2d and 0.2e
 233 ======================================
 234
 235 1.      Fixed a bug in the "set owner/mode" process.  Every file was restored
 236         with owner = root (0) and group = root/wheel/whatever (0).
 237
 238 Changes between versions 0.2c and 0.2d
 239 ======================================
 240
 241 1.      Dump is now able to backup 2GB+ filesystems.
 242
 243 2.      Dump and restore can now be linked as static binaries.
 244
 245 Changes between versions 0.2b and 0.2c
 246 ======================================
 247
 248 1.      Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
 249
 250 Changes between versions 0.2a and 0.2b
 251 ======================================
 252
 253 1.      Really fixed the bug that I should have corrected in 0.2a.
 254
 255 2.      Enabled optimization again.
 256
 257 Changes between versions 0.2 and 0.2a
 258 =====================================
 259
 260 1.      Disabled the optimization during compilation.
 261
 262 Changes between versions 0.1 and 0.2
 263 ====================================
 264
 265 1.      Fixed a bug in fstab.c which caused a null pointer to be stored in
 266         the fs_type field (actually, I modified the file fstab.c to make it
 267         use the mntent functions).
 268
 269 2.      Dump and restore now use a 4.3 BSD compatible dump format.  Backups
 270         made by dump should be readable by the BSD restore and backups made
 271         by the BSD dump should be readable by restore.  Unfortunately, this
 272         means that the dump format has changed between version 0.1 and version
 273         0.2 :-(
 274
 275 3.      Dump is now able to backup a subtree, it is no longer limited to whole
 276         filesystems like the BSD version.
 277
 278 4.      Dump now uses ext2_llseek() so it is able to backup filesystems bigger
 279         than 2 GB.
 280
 281 Changes between versions 0.0 and 0.1
 282 ====================================
 283
 284 1.      Now create links rdump and rrestore during the `make install' step.
 285
 286 2.      Linux port specific bugs added to the manual pages
 287
 288 3.      Incorrect estimation of the number of tapes blocks fixed when doing
 289         incremental backups.
 290
 291 4.      Better ls-like format in restore in interactive mode.
