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