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