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