   3 Changes between versions 0.4b11 and 0.4b12 (released ????????????????)
   4 ======================================================================
   5
   6 1.      Small fix in the dump man page. Thanks to Thorsten Kukuk
   7         <kukuk@suse.de> for submitting the patch.
   8
   9 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
  10 ======================================================================
  11
  12 1.      Added a '--enable-kerberos' to configure.
  13
  14 2.      Added a 'S' option to dump which determines the amount of space
  15         that is needed to perform the dump without actually doint it, similar
  16         to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
  17         <cermak@ahab.rutgers.edu>.
  18
  19 3.      Added a 'M' multi-volume option to dump and restore which enables
  20         dumping to multiple files (useful when dumping to an ext2
  21         partition to make several dump files in order to bypass the 2GB
  22         file size limitation). The 'f' argument is treated as a prefix and
  23         the output files will be named <prefix>001, <prefix>002 etc. With
  24         the 'M' flag, restore automatically selects the right file without
  25         asking to enter a new tape each time.
  26
  27 4.      Fixed a memory leak which was causing dump to grow very big
  28         (270MB when dumping a 10GB filesystem...). Thanks to Zaphod
  29         Beeblebrox <zaphod@netrider.org.au> for reporting the bug.
  30
  31 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
  32 ======================================================================
  33
  34 1.      Make configure test if the system glob routines support
  35         extended syntax (ALTDIRFUNC). If not, use the internal glob
  36         routines instead of system ones. Thanks to Bernhard Sadlowski
  37         <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
  38         and helping me resolve this and other minor libc5 compiling
  39         glitches.
  40
  41 2.      Fix a problem when dumping a ext2fs with the 'filetype'
  42         feature enabled. Thanks to Patrick J. LoPresti
  43         <patl@cag.lcs.mit.edu> for reporting the bug and to
  44         Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
  45
  46 3.      Made the nodump flag work on directories. A directory which
  47         has the nodump flag gets never dumped, regardless of its
  48         contents.
  49
  50 4.      Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
  51         which allows dump on an active ext3 filesystem. However, this
  52         is a "quick and dirty" patch which enables backup of an ext3
  53         filesystem through the ext2 compatibility (by ignoring the
  54         NEEDS_RECOVERY bit). The journal file is not recognized and
  55         it is dumped (it should not).
  56
  57 5.      Test the superblock compatibility flags when dumping, in order
  58         to be sure that we know how to deal with specific features.
  59
  60 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
  61 ====================================================================
  62
  63 1.      Use lchown instead of chown, fixing a possible security problem
  64         when restoring symlinks (a malicious user could use this
  65         to deliberately corrupt the ownership of important system files).
  66         Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
  67         this and providing the patch.
  68
  69 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
  70 ====================================================================
  71
  72 1.      Put dump sources under CVS, added Id tags in all files so
  73         one can use 'ident' on binary files.
  74
  75 2.      Added the dump/restore version in the usage text so one can
  76         easily verify the version he is using.
  77
  78 3.      Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
  79         a va_start/va_end problem on linux-ppc (always call va_start
  80         va_end in pairs each time we use a vararg function).
  81
  82 4.      Added again the DT_* constants because old libc does not
  83         contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
  84         for submitting the bug report.
  85
  86 5.      Use ext2fs_llseek instead of llseek. With recent e2fsprogs
  87         this should enable dumping big (huge) filesystems.
  88
  89 6.      Added the RSH environment variable in order to be able to
  90         use a rsh replacement like ssh when doing remote backups (and
  91         bypass the security limitations of rcmd). Now you can do remote
  92         backups without being root (or making dump setuid root).
  93
  94 7.      Modified again the way dumpdates works. For incremental dumps,
  95         we need to read dumpdates even if we are not using 'u' option.
  96         Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
  97         this should work.
  98
  99 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
 100 ===================================================================
 101
 102 1.      Removed the 'k' flag from the restore 'about' text if kerberos
 103         was not compiled in.
 104
 105 2.      Prototyped (f)setflags from e2fsprogs and corrected the calls
 106         to them (fsetflags takes a char*, setflags an open fd!).
 107
 108 3.      (f)setflags is called only if the flags aren't empty. If the
 109         file is a special file, a warning is printed, because changing
 110         flags implies opening the device. Normally, a special file
 111         should not have any flag... (Debian bug #29775, patch provided
 112         by Abhijit Dasgupta <abhijit@ans.net>).
 113
 114 4.      Made possible to dump a file system not mentioned in /etc/fstab.
 115         (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
 116
 117 5.      Changed the default behaviour to not create dumpdates
 118         unless 'u' option is specified. Removed the old "debian-patch"
 119         which provided the same thing. (Debian bug #38136, #33818).
 120
 121 6.      Removed all those dump*announce, since they were getting old...
 122
 123 7.      Added warning messages if dumpdates does not exist and
 124         when an inferior level dump does not exist (except for a level 0
 125         dump).
 126
 127 8.      Debugged the glob calls in interactive mode: restore used a
 128         dirent struct which was different from the /usr/include/dirent.h
 129         one (this used to work, is it a glibc2 change?), so none of the
 130         compat glob (which used /usr/include/dirent.h) or the system glob
 131         worked. Restore use now the system dirent (and the system
 132         DT_* constants), which are compatible with BSD ones.
 133
 134 9.      Added a configure flag (--with-dumpdatespath) to specify
 135         the location of dumpdates file. By default, it is
 136         /etc/dumpdates.
 137
 138 10.     Added the "AUTHOR" and "AVAILABILITY" sections and
 139         included the current date/version in man pages.
 140
 141 11.     Corrected the estimation of remaining time when
 142         the operator doesn't change the tapes quickly enough. This
 143         was an old bug, I thought I corrected it, and discovered
 144         that in fact it was corrected in two different places, so
 145         the results canceled each other...
 146
 147 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
 148 ===================================================================
 149
 150 1.      Integrated multiple patches from RedHat, Debian and SuSE:
 151
 152         - tweak dump/itime.c to not try to read dumpdates if the 'u' option
 153           isn't specified.
 154         - several fixes in the man pages.
 155         - update the default tape device to /dev/st0.
 156         - many updates for Linux Alpha (byte ordering, size_t etc).
 157         - buffer overruns.
 158         - use environment variable for TMPDIR (instead of /tmp).
 159         - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
 160         - workaround egcs bug (RedHat bugs #4281 and #2989).
 161         - wire $(OPT) throughout Makefile's.
 162
 163 2.      Upgrade the dump revision to 1, making possible to dump filesystems
 164         made with e2fsprogs-1.15 or newer. Nothing seems to break...
 165
 166 3.      Fix some compile warnings, prototype all functions.
 167
 168 4.      Use glibc err/glob instead of internal compatibility
 169         routines (only if available).
 170
 171 5.      Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
 172         by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
 173
 174 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
 175 ======================================================================
 176
 177 1.      Integrated the changes from FreeBSD-3.1-RELEASE
 178         (mostly bug fixes, buffer overruns, dump has now an "automatic
 179         tape length calculation" flag, dump/restore can use kerberos now
 180         (this is NOT tested), use environment variables for TAPE and
 181         RMT etc.).
 182
 183 2.      Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
 184
 185 3.      Corrected a bug in restore when using 'C' option with multi-volumes
 186         tapes (files splited accros two tapes give "size changed" errors
 187         when comparing).
 188
 189 4.      Corrected the long standing bug when dumping multiple tapes.
 190         This works for me, needs further testing.
 191
 192 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
 193 ====================================================================
 194
 195 1.      Dump now runs correctly on kernels 2.1.x
 196         Fix made by Gerald Peters <gapeters@worldnet.att.net>
 197
 198 Changes between versions 0.4b2 and 0.4b3
 199 ========================================
 200
 201 1.      Use realpath() if available
 202
 203 2.      Report statistics
 204
 205 Changes between versions 0.4b1 and 0.4b2
 206 ========================================
 207
 208 1.      Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
 209         the patch)
 210
 211 2.      Fixed restore to make it able to read FreeBSD 2.x dumps again
 212
 213 3.      Fixed configure.in to correctly handle --enable-rmt
 214
 215 Changes between versions 0.3 and 0.4b1
 216 ======================================
 217
 218 1.      Integrated the changes from 4.4BSD-Lite2
 219
 220 2.      Integrated the patches from Debian and Red Hat
 221
 222 3.      Portability changes: use the __u32, __u16, __s32, and __s16 types
 223
 224 4.      Changed dump to use the Ext2fs library to get block addresses.  This
 225         should solve the endianness problem on SparcLinux.
 226
 227 5.      Created a configure.in file (shamelessly stolen from the e2fsprogs
 228         distribution's one) to use autoconf
 229
 230 6.      Fixed a few minor bugs
 231
 232 Changes between versions 0.2e and 0.2f
 233 ======================================
 234
 235 1.      Added the creation of named pipes (fifos) in restore.
 236
 237 2.      Added the -N flag in the restore manual page.
 238
 239 3.      Added the file kernel.patch which contains the llseek() optimization
 240         patch for 1.2.x kernels.
 241
 242 4.      Fixed a bug in the restoration of symbolic links: owner and group were
 243         not restored.
 244
 245 5.      Integrated some changes from FreeBSD 2.2.
 246
 247 6.      Added a call to ftruncate() after restoring each file to restore
 248         correctly files ending by a hole.
 249
 250 Changes between versions 0.2d and 0.2e
 251 ======================================
 252
 253 1.      Fixed a bug in the "set owner/mode" process.  Every file was restored
 254         with owner = root (0) and group = root/wheel/whatever (0).
 255
 256 Changes between versions 0.2c and 0.2d
 257 ======================================
 258
 259 1.      Dump is now able to backup 2GB+ filesystems.
 260
 261 2.      Dump and restore can now be linked as static binaries.
 262
 263 Changes between versions 0.2b and 0.2c
 264 ======================================
 265
 266 1.      Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
 267
 268 Changes between versions 0.2a and 0.2b
 269 ======================================
 270
 271 1.      Really fixed the bug that I should have corrected in 0.2a.
 272
 273 2.      Enabled optimization again.
 274
 275 Changes between versions 0.2 and 0.2a
 276 =====================================
 277
 278 1.      Disabled the optimization during compilation.
 279
 280 Changes between versions 0.1 and 0.2
 281 ====================================
 282
 283 1.      Fixed a bug in fstab.c which caused a null pointer to be stored in
 284         the fs_type field (actually, I modified the file fstab.c to make it
 285         use the mntent functions).
 286
 287 2.      Dump and restore now use a 4.3 BSD compatible dump format.  Backups
 288         made by dump should be readable by the BSD restore and backups made
 289         by the BSD dump should be readable by restore.  Unfortunately, this
 290         means that the dump format has changed between version 0.1 and version
 291         0.2 :-(
 292
 293 3.      Dump is now able to backup a subtree, it is no longer limited to whole
 294         filesystems like the BSD version.
 295
 296 4.      Dump now uses ext2_llseek() so it is able to backup filesystems bigger
 297         than 2 GB.
 298
 299 Changes between versions 0.0 and 0.1
 300 ====================================
 301
 302 1.      Now create links rdump and rrestore during the `make install' step.
 303
 304 2.      Linux port specific bugs added to the manual pages
 305
 306 3.      Incorrect estimation of the number of tapes blocks fixed when doing
 307         incremental backups.
 308
 309 4.      Better ls-like format in restore in interactive mode.
