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