11eb67eec9 Some memory allocation improvements 
- All the memory-allocation macros now auto-check for failure and exit
   with a failure message that incudes the caller's file and lineno
   info.  This includes strdup().

 - Added the `--max-alloc=SIZE` option to be able to override the memory
   allocator's sanity-check limit.  It defaults to 1G (as before).
   Fixes bugzilla bug 12769.

888ce058d8 Two sparse fixes from Yuxuan Shui. 
- Make "len" parameter of do_punch_hole an OFF_T.
- Clear sparse_past_write in sparse_end(), otherwise when write_sparse()
  is called for the next file, do_punch_hole() will be called with a pos
  that's not actually the current position in file, causing it to fail.

f3873b3d88 Support --sparse combined with --preallocate or --inplace. 
The new code tries to punch holes in the destination file using newer
Linux fallocate features. It also supports a --whole-file + --sparse +
--inplace copy on any filesystem by truncating the destination file.

7d7538d43c Fix error in write_sparse() on incomplete write. 
Fix a problem where sparse_seek could get left non-zero when we
did not finish writing all the data that would take us to that
sparse gap.  Issue pointed out by David Taylor.

adc2476fa2 Output numbers in 3-digit groups by default (e.g. 1,234,567). 
Also improved the human-readable output functions, including
adding the ability to output negative numbers.

6aa27a7ce5 - Do less seeking when writing a sparse file. 
- Don't rewrite the last byte of a file in sparse mode when the
  file didn't end with a null char.

- Added some missing copyright lines.
- Some minor whitespace tweaks (in a few of the files).

1348267518 If we get less data than expected from a read() in map_ptr(), we

705de51a73 Improved do_lseek()'s failure message. 2005-02-27 21:12:13 +00:00
Wayne Davison
54281fe733 - Changed the map_size parameter to map_file() to be an int32 named 
"read_size".
- Changed some int vars in map_ptr() needed to be int32 vars.
- All callers expect map_ptr() to return back the full "len" bytes,
  so we never shorten this value, even near EOF--the read will
  just get zero-padded, as needed.
- Die with an error if someone calls map_ptr() with a len < 0, or
  if read_size is computed as a value < 0.

7aac6604c4 - Use an int32 for the each block-size variable. 
- Renamed the local block_size arg to blk_size (to avoid
  confusion with the global block_size variable).
 2005-01-01 21:08:07 +00:00
Wayne Davison
6e8a1782ab - Changed the calling syntax for map_file() so that it takes both 
a (possibly approximate) window size and an optional block size
  (which is used to round-up the window size if it is non-zero).
- Don't set window_start behind the supplied offset in map_ptr().
 2004-08-03 08:05:29 +00:00
Wayne Davison
7f290d5c82 - Added a new block_size arg to map_file(). Use it to set the 
new def_window_size member variable.
- Got rid of max_map_size global (we use def_window_size now).

9dd891bb28 Signedness security patch from Sebastian Krahmer <krahmer@suse.de> -- 
in some cases we were not sufficiently careful about reading integers
from the network.

Also, make sure log messages are always nul-terminated.

4440b8aa3f no longer use mmap() in rsync because of the risk of a SIGBUS when 
another program (such as a mailer) truncates a file.

To offset the speed loss I have rewritten the map_ptr() code to make
much better use of read().
