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