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