Stefan Hengl scoring: use repo freshness as tiebreaker (#832) 2y ago

scoring: use repo freshness as tiebreaker (#832) We ignore priority and instead use the latest commit date as repo rank. This has a big impact for Sourcegraph because it means we switch from star count to repo freshness as tiebreaker. As a minor tweak, we also separate query based scores from tiebreakers. To achieve this we reserve the last 7 digits of a score for tiebreakers: - 5 digits (maxUint16) for repo rank - 2 digits ([0,10]) for file order (2 digits). Example: Before: score: 8775.35 <- atom(2):200, fragment:8550.00, repo-rank: 19, doc-order:6.35 After: score: 8750_00019_06.35 <- atom(2):200, fragment:8550.00, repo-rank: 19, doc-order:6.35

Report GCP profiles from zoekt-git-index (#816) This PR initializes the GCP profiler in the `zoekt-git-index` process so we can examine CPU and memory usage for the indexing process itself.

all: use a faster vendored regexp/syntax/Regexp.String (#753) We replace all calls to Regexp.String with a vendored version which is faster. go1.22 introduced a commit which "minimizes" the string returned by Regexp.String(). Part of what it does is run enumerate through literals runes in your string to see calculate flags related to unicode and case sensitivity. This can be quite slow, but is made worse by the fact we call it per shard per regexp in your query.Q to construct the matchtree. Currently Regexp.String() represents 40% of CPU time on sourcegraph.com. Before go1.22 it was ~0%. Note: This is a temporary change to resolve the issue. I have a deeper change to make this less clumsy. Note: In one place we remove the use of string by relying on Regexp.Equal instead. Test Plan: go test
