Sqinn-Go VS hyperscan

Note that Squinn is not "native go" or "go only", but the owner insists on misleading people:

If you want to avoid cgo, consider sqinn as well: benchmarks.

Of course, it may seem... odd to add a remote interface to an embedded database, but I think that it fits some niches well, especially when decoupling persistence and logic is needed, without renouncing to the expressivity of SQL. It was inspired by PostgREST, but it’s much more “low level” – and it should be even simpler to adapt to some cases. Also, it serves the same purpose of sqinn but with a more general interface.

Why don't you try a pure-Go implementation? Should have enough features implemented for basic use

Maybe some other PCRE-compatible implementation offers streaming. For instance, https://www.intel.com/content/www/us/en/developer/articles/t... says it has this feature, but of course given who it's from it may be tied to a single brand of CPU.

I think of WAFs as an extra safety net. Defense in depth.

The author complained about the performance cost of WAFs in general, but not all WAFs have be structured like ModSecurity. They could for example be based on something like https://github.com/intel/hyperscan and perf is at a very different level.

Another example of old timey Unix code just breaking things in minor point releases. See https://abi-laboratory.pro/index.php?view=changelog&l=glibc&... and https://github.com/intel/hyperscan/issues/359.

It’s a bespoke scanning setup designed to deal with GitHub’s scale. Under the hood it’s using Intel’s hyperscan as the regex engine.

Hyperscan is an Intel regular expression library.

We are using hyperscan [3] instead of grepping byte sequences with Python, which is orders of magnitudes faster. It can also handle 4Gb+ files because of this which binwalk cannot.

It's used for a year now in production and it's way more precise and faster than binwalk. We are getting less false-positives too, and even if unblob fails to extract everything, we still get meaningful information out of firmwares, where binwalk just failed with no output previously.
