Optimizations

#​1909 waits to find newlines until a match. This ends up saving a boat load of time since before we were finding newlines for every fragment regardless if a rule matched or not.
#​1908 promoted @​rgmz excellent stopword optimization

Composite Rules (Multi-part or required Rules) #​1905

In v8.28.0 Gitleaks introduced composite rules, which are made up of a single "primary" rule and one or more auxiliary or required rules. To create a composite rule, add a [[rules.required]] table to the primary rule specifying an id and optionally withinLines and/or withinColumns proximity constraints. A fragment is a chunk of content that Gitleaks processes at once (typically a file, part of a file, or git diff), and proximity matching instructs the primary rule to only report a finding if the auxiliary required rules also find matches within the specified area of the fragment.

Proximity matching: Using the withinLines and withinColumns fields instructs the primary rule to only report a finding if the auxiliary required rules also find matches within the specified proximity. You can set:

• withinLines: N - required findings must be within N lines (vertically)
• withinColumns: N - required findings must be within N characters (horizontally)
• Both - creates a rectangular search area (both constraints must be satisfied)
• Neither - fragment-level matching (required findings can be anywhere in the same fragment)

Here are diagrams illustrating each proximity behavior:

p = primary captured secret
a = auxiliary (required) captured secret
fragment = section of data gitleaks is looking at
