Attached is a patch that makes window strides constant when files are walked with a constant block size. In these cases, it completely avoids all memmoves. In my simple local test of rsyncing 57MB of 10 local files, memmoved bytes went from 18MB to zero. I haven't tested this for a big variety of file cases. I think that this will always reduce the memmoves involved with walking a large

...c from the latest zlib distribution so we can call gzwrite() etc. What remains to be done / problems: - Needs more testing, especially with remote clients / servers. - Batch files are not compressed. - Reading compressed files should be implemented in a more generic fashion, perhaps in map_file() and its cousins. I started working on this but saw that changing map_file() et al. could have far reaching consequences, so I took the easy way out: I just changed the one routine I cared about for now. - Add documentation of new options to manpages etc. - Find a way to write down...

...am thinking of is in an if(!read_batch) block and the CRC/deltas are under if(read_batch). Is read_batch always true when using --whole-files? Seems to be. Second concern: where is the reading and transmission of th file happening? If the do_open is in line 183, where's the read/transmit, map_file() line 202 puts the data uin buf, and then, what? You see, write_int doesn't use buf. And where is the handle closed? Thanks for any tips here... Ahhh, life. martin http://nzl.com.ar/

The main changes are to fileio.c in the map_file() function, which I've restructured a little to allow for retrying errors, delaying before retrying errors, and filling the read buffer with an arbitrary byte to make the identification of unrecovered data easier. The three options are: --retry-errors=NUM, which retries the residue of a fail...
