...removes many asserts and quite a bit of unreachable code (eg. Python code for handling ArrayAndLen in normal methods that was never used). The output of the generator after this commit should be identical. It's possible to go a little further if we wanted: CBArrayAndLen is only ever used for ‘uint32_t’ arrays. CBMutable is only ever used for ‘int*’. We could make CB* types which only handle those cases. --- generator/generator | 428 +++++++++++++++++++------------------------- 1 file changed, 186 insertions(+), 242 deletions(-) diff --git a/generator/generator b/generator/generator index...

Hello everyone, I discovered a way to perform optimization on the following code (I gave an example that uses 32bit integer, but it works with any size.): const uint32 d,r;//d is an odd number //d is the divisor, r is the remainder bool check_remainder(uint32 x) { return x%d==r; } if we know d and r at compile time, and d is an odd integer, we can use modular multiplicative inverse to bypass the division operation. I wrote the following code to calculate the M.M...

These are some simplifications to the generator. They don't probably make much sense on their own, but they are preparatory to better handling of enums, and or'd lists of flags. Rich.

RFC because this is an API break, but we haven't declared stable API yet. If we like it, I'm working on using libnbd to implement the nbdkit-nbd plugin; knowing whether it is API version 0.1 or 0.2 will be useful. I also dabbled with allowing optional parameters in python, although my OCaml is weak enough that there may be cleaner ways to approach that. Eric Blake (4): api: Add flags

Commit 6725fa0e12 changed copy_uint32_array() to utilize a Go hack for accessing a C array as a Go slice in order to potentially benefit from any optimizations in Go's copy() for bulk transfer of memory over naive one-at-a-time iteration. But that commit also acknowledged that no benchmark timings were performed, which would have...
