Sorry for the radio silence. Is there a reason you need us to build these binaries? Ultimately, what we would build would just be the result of `git clone https://github.com/facebook/zstd...

In the absence of a reply, I'm going to close the issue. If you want to discuss further, please feel free to re-open.

Based on [Section 5](https://datatracker.ietf.org/doc/html/draft-ietf-httpbis-digest-headers#name-hash-algorithm-consideratio)'s description of the registration criteria, we could register xxHash even though it is not cryptographically secure or standardized in an RFC. @vanmierlo, do you have a...

The alternative floated where `zstd-d`'s window size is derived from the size of the dictionary is much more attractive to me. (That is, cap the window size log at `ceil(log_2(clamp(8...

@pmeenan, yeah, that would be pretty straightforward. Happy to add that.

> [...] won't the 1/8th power of 2 granularity apply even for cases where the resource is the same size (or sometimes smaller) than the dictionary? Yes. (Keeping in mind...

Can you be more specific? Zstd does have negative compression levels. They are available both in the command-line tool (via `--fast=N`) and in the library methods (by passing a negative...

@pizzard, if the `zstd` CLI supported this splitting of frames, how would you find the frame boundaries when doing your binary search? Would you want each frame to be a...

Oh I see. You're running this test as `root`. This test attempts to create an unwritable directory ([here](https://github.com/facebook/zstd/blob/v1.5.5/tests/cli-tests/file-stat/compress-file-to-dir-without-write-perm.sh#L6-L7)). But root can write to it even with `000` permissions. I'm not...

To answer your immediate question: this functionality does not exist. Here's why: in order to decompress an object compressed with a dictionary, you need to present exactly the same dictionary...
