Getting the latest version: bzip2 1.0.2


1.0.2
~~~~~
A bug fix release, addressing various minor issues which have appeared
in the 18 or so months since 1.0.1 was released.  Most of the fixes
are to do with file-handling or documentation bugs.  To the best of my
knowledge, there have been no data-loss-causing bugs reported in the
compression/decompression engine of 1. or 1.0.1.

Note that this release does not improve the rather crude build system
for Unix platforms.  The general plan here is to autoconfiscate/
libtoolise 1.0.2 soon after release, and release the result as 1.1.0
or perhaps 1.2.0.  That, however, is still just a plan at this point.

Here are the changes in 1.0.2.  Bug-reporters and/or patch-senders in
parentheses.

* Fix an infinite segfault loop in 1.0.1 when a directory is
  encountered in -f (force) mode.
     (Trond Eivind Glomsrod, Nicholas Nethercote, Volker Schmidt)

* Avoid double fclose() of output file on certain I/O error paths.
     (Solar Designer)

* Don't fail with internal error 1007 when fed a long stream (> 48MB)
  of byte 251.  Also print useful message suggesting that 1007s may be
  caused by bad memory.
     (noticed by Juan Pedro Vallejo, fixed by me)

* Fix uninitialised variable silly bug in demo prog dlltest.c.
     (Jorj Bauer)

* Remove 512-MB limitation on recovered file size for bzip2recover
  on selected platforms which support 64-bit ints.  At the moment
  all GCC supported platforms, and Win32.
     (me, Alson van der Meulen)

* Hard-code header byte values, to give correct operation on platforms
  using EBCDIC as their native character set (IBM's OS/390).
     (Leland Lucius)

* Copy file access times correctly.
     (Marty Leisner)

* Add distclean and check targets to Makefile.
     (Michael Carmack)

* Parameterise use of ar and ranlib in Makefile.  Also add $(LDFLAGS).
     (Rich Ireland, Bo Thorsen)

* Pass -p (create parent dirs as needed) to mkdir during make install.
     (Jeremy Fusco)

* Dereference symlinks when copying file permissions in -f mode.
     (Volker Schmidt)

* Majorly simplify implementation of uInt64_qrm10.
     (Bo Lindbergh)

* Check the input file still exists before deleting the output one,
  when aborting in cleanUpAndFail().
     (Joerg Prante, Robert Linden, Matthias Krings)

Also a bunch of patches courtesy of Philippe Troin, the Debian maintainer
of bzip2:

* Wrapper scripts (with manpages): bzdiff, bzgrep, bzmore.

* Spelling changes and minor enhancements in bzip2.1.

* Avoid race condition between creating the output file and setting its
  interim permissions safely, by using fopen_output_safely().
  No changes to bzip2recover since there is no issue with file
  permissions there.

* do not print senseless report with -v when compressing an empty
  file.

* bzcat -f works on non-bzip2 files.

* do not try to escape shell meta-characters on unix (the shell takes
  care of these).

* added --fast and --best aliases for -1 -9 for gzip compatibility.
