2006-03-15diffcore-delta: 64-byte-or-EOL ultrafast replacement (hash fix).Linus Torvalds
The rotating 64-bit number was not really rotating, and worse yet ulong was longer than 64-bit on 64-bit architectures X-<. Signed-off-by: Junio C Hamano <>

2006-03-13diffcore-delta: tweak hashbase value.Junio C Hamano
This tweaks the maximum hashvalue we use to hash the string into without making the maximum size of the hashtable can grow from the current limit. With this, the renames detected becomes a bit more precise without incurring additional paging cost. Signed-off-by: Junio C Hamano <>
2006-03-13diffcore-delta: make the hash a bit denser.Junio C Hamano
To reduce wasted memory, wait until the hash fills up more densely before we rehash. This reduces the working set size a bit further. Signed-off-by: Junio C Hamano <>
2006-03-12diffcore-rename: somewhat optimized.Junio C Hamano
This changes diffcore-rename to reuse statistics information gathered during similarity estimation, and updates the hashtable implementation used to keep track of the statistics to be denser. This seems to give better performance. Signed-off-by: Junio C Hamano <>
2006-03-04diffcore-delta: make change counter to byte oriented again.Junio C Hamano
The textual line oriented change counter was fun but was not very effective. It tended to overcount the changes. This one changes it to a simple N-letter substring based implementation. Signed-off-by: Junio C Hamano <>
2006-03-01diffcore-rename: split out the delta counting code.Junio C Hamano
This is to rework diffcore break/rename/copy detection code so that it does not affected when deltifier code gets improved. Signed-off-by: Junio C Hamano <>
