changelog

rsync的核心代码库。主要作用是比较二进制文件

2001-03-18 22:01  mbp

	* mksum.c: Do stats on signatures.

	  Add rs_trace_enabled() so that we can avoid spending too much
	  time generating trace output if it's not going to be used.

2001-03-18 21:59  mbp

	* mdfour.c: Make MD4 40% faster! :-)

	  Eliminate redundant copying of information.  If we're on a
	  little-endian machine, do the calculations directly, and don't do
	  byte swapping.  Use an exact uint32 type.  Don't copy into the
	  tail of the MD4 accumulator unless there's already something
	  there.

2001-03-18 21:58  mbp

	* job.h: Do rolling checksums in deltas.

	  Do stats on signatures.

2001-03-18 21:57  mbp

	* driver.sh: Fix output format for countdown()

2001-03-18 21:56  mbp

	* checksum.c, checksum.h, delta.c: Use rolling checksums when
	  generating deltas.  (This seems to work, but in very rare cases
	  --paranoid finds a mismatch -- I'll check.)

	  Fix float output formats.

2001-03-18 21:55  mbp

	* NEWS: Doc.

2001-03-18 21:54  mbp

	* mutate.pl: Bias changes towards smaller sizes -- this is more
	  realistic.

	  Add a little user-friendliness.

2001-03-18 21:53  mbp

	* rdiff.c: Add --paranoid option to double-check rolling sums.

	  Explain that --gzip and --bzip2 don't work yet.

	  Do stats on signature and loadsig operations.

2001-03-18 21:52  mbp

	* readsums.c, patch.c, netint.c: Fix float output formats.

	  Add rs_trace_enabled() so that we can avoid spending too much
	  time generating trace output if it's not going to be used.

2001-03-18 21:51  mbp

2001-03-18 21:50  mbp

	* trace.c, trace.h: Check that %ld in trace statements is going to
	  work.

	  Add rs_trace_enabled() so that we can avoid spending too much
	  time generating trace output if it's not going to be used.

2001-03-18 21:49  mbp

	* rollsum.c, rollsum.h, sumset.h: rollsum_t is no longer used.

2001-03-18 21:48  mbp

	* whole.c, rsync.h: Do signatures on signature and loadsig
	  operations.

2001-03-18 21:48  mbp

	* types.h: Make sure we find a real uint32 type, so that MD4 code
	  can assume it's correct and be faster.

2001-03-18 21:47  mbp

	* configure.in: Drop explicit off64_t stuff from Samba, and instead
	  use the AC_SYS_LARGEFILE macro.

	  Check more integer sizes.

2001-03-18 21:47  mbp

	* acinclude.m4: Drop explicit off64_t stuff from Samba, and instead

	* job.c, whole.c, buf.c, buf.h: Add rs_job_drive, a generic
	  mechanism for turning the library into blocking mode.

	  it.

2001-03-18 12:59  mbp

	* rdiff.c: Accept gzip and bzip2 options.  Doesn't actually do

2001-03-18 12:41  mbp

	* NEWS: Suggestions to build on Solaris 2.6 from Alberto Accomazzi
	  <[e-mail]>

	  Add rs_job_drive, a generic mechanism for turning the library

	* sources.test: Also compare source to itself as the null case.

2001-03-13 00:15  mbp

	* driver.sh: Driver now takes a -s option to make it show
	  statistics.

2001-03-13 00:13  mbp

	* delta.c: Update the delta_scan routine to be able to do short end
	  blocks.

2001-03-13 00:02  mbp

2001-03-12 18:29  mbp

	* stats.c: Fix printf format.

2001-03-12 18:27  mbp

	* scoop.c, tube.c: Better trace.

	  cmdbytes.

2001-03-12 18:22  mbp

	* rsync.h: Fix rs_file_copy_cb, which needs to know the position at
	  which to copy.  Show fd# if copy fails.

	  Doc.

2001-03-12 18:21  mbp

	* buf.c: Fix rs_file_copy_cb, which needs to know the position at
	  which to copy.  Show fd# if copy fails.

2001-03-12 14:41  mbp

	* patch.c: Add code to parse COPY commands.  Doesn't execute them
	  yet.

	  Automatically stick immediate operands into job->param1.

2001-03-12 14:32  mbp

	* delta.c: W00h00!  Search for matching blocks and emit COPY

	* scoop.c: Doc.

2001-03-12 14:28  mbp

	* emit.c, emit.h: Add rs_emit_copy_cmd, with hardcoded cmdbyte.

2001-03-12 13:31  mbp

	* delta.c: Calculate checksums of full-size blocks in preparation
	  for searching.  Still just emit literals.

	  Sanity-check signature settings at job creation.

	  If there's not enough input data to search for a block, then put
	  what we have into the scoop so that we can keep it for later.

2001-03-12 13:28  mbp

	* scoop.c, stream.h: Expose rs_scoop_input.

2001-03-12 13:23  mbp

	* util.h: Drop unused macros.

2001-03-12 13:16  mbp

	* job.c: More verbose internal error message.

2001-03-12 12:57  mbp

	* rsync.h: Fix Doxygen references.

2001-03-12 12:43  mbp

	* delta.c: When generating a delta, get as much readahead as
	  possible so that we can generate the best deltas.  Move code to
	  actually scan out into a separate function.  Still just always
	  emitting deltas.

2001-03-12 12:42  mbp

	* job.h, mksum.c, netint.c, patch.c, stream.c, stream.h, tube.c:
	  Rename rs_blow_* to rs_tube_*.

	  Rename rs_blow_literal to rs_tube_write, because it otherwise
	  tends to get confused with LITERAL commands.

2001-03-12 12:30  mbp

	* main.dox: More documentation of buffers structure.

2001-03-12 12:09  mbp

	  said it did, so as to better detect internal errors.

2001-03-12 12:08  mbp

	* emit.c: Include statistics about space used by command headers,
	  and the total bytes read and written.

2001-03-12 12:02  mbp

	* rsync.h, stats.c: Include statistics about space used by command
	  headers, and the total bytes read and written.

2001-03-12 11:33  mbp

	* tube.c: Factor out code to copy from scoop.

2001-03-12 11:04  mbp

	* tube.c: Better trace.

	  Doc.

	  When copying data through to the tube, make sure we use up data
	  in the scoop first!

2001-03-12 11:04  mbp

	* trace.c, trace.h: Fix oops about RS_LOG_NONAME.

2001-03-12 11:03  mbp

	* stream.c, stream.h: Get ready for readahead searching for
	  matching blocks.

	  Don't both copying if there are zero bytes left.

2001-03-12 11:01  mbp

	* scoop.c: Get ready for readahead searching for matching blocks.

2001-03-12 11:01  mbp

	* rdiff.c: Get ready for built-in gzip/bzip2 support.

	  Make sure we suggest --help when somebody makes a command-line
	  mistake.

2001-03-12 11:00  mbp

	* msg.c: Improved error messages.

2001-03-12 10:59  mbp

	* delta.c, job.h: When generating a delta, if there is a signature
	  loaded then use a different statefn that tries to get enough
	  readahead to look for a match.  At the moment it just outputs
	  LITERALs, but it's closer.

	  Copy signature parameters into the job, so block_len is available
	  for deltas.

2001-03-12 10:57  mbp

	* configure.in: Look for libz and libbz2 so that we can later try
	  using them in rdiff.

2001-03-12 01:41  mbp

	* includes.h: no longer required

2001-03-12 01:41  mbp

	* stats.c, trace.c, trace.h: Optionally hide function name in trace
	  output.  Do this when displaying statistics.

2001-03-12 01:41  mbp

	* sumset.h: Doc.

2001-03-12 01:18  mbp

	* configure.in: Call this 0.9.2pre.

2001-03-12 01:17  mbp

	* Makefile.am, autogen.sh: Cater to people who prefer the name
	  'make test'.

2001-03-12 01:16  mbp

	* buf.c: Doc.

2001-03-12 01:16  mbp

	* librsync.3: Fix man page markup.

2001-03-12 01:14  mbp

	* Makefile.am: Make manpages look better.

2001-03-12 01:03  mbp

	* Makefile.am: Build man pages and converted forms.  Upload
	  converted man pages to websites.

2001-03-12 00:52  mbp

	* trace.c, rdiff.c: Doc.
