/**
|
|
* Matches block comment delimiters
|
|
*
|
|
* While most of this pattern is straightforward the attribute parsing
|
|
* incorporates a tricks to make sure we don't choke on specific input
|
|
*
|
|
* - since JavaScript has no possessive quantifier or atomic grouping
|
|
* we are emulating it with a trick
|
|
*
|
|
* we want a possessive quantifier or atomic group to prevent backtracking
|
|
* on the `}`s should we fail to match the remainder of the pattern
|
|
*
|
|
* we can emulate this with a positive lookahead and back reference
|
|
* (a++)*c === ((?=(a+))\1)*c
|
|
*
|
|
* let's examine an example:
|
|
* - /(a+)*c/.test('aaaaaaaaaaaaad') fails after over 49,000 steps
|
|
* - /(a++)*c/.test('aaaaaaaaaaaaad') fails after 85 steps
|
|
* - /(?>a+)*c/.test('aaaaaaaaaaaaad') fails after 126 steps
|
|
*
|
|
* this is because the possessive `++` and the atomic group `(?>)`
|
|
* tell the engine that all those `a`s belong together as a single group
|
|
* and so it won't split it up when stepping backwards to try and match
|
|
*
|
|
* if we use /((?=(a+))\1)*c/ then we get the same behavior as the atomic group
|
|
* or possessive and prevent the backtracking because the `a+` is matched but
|
|
* not captured. thus, we find the long string of `a`s and remember it, then
|
|
* reference it as a whole unit inside our pattern
|
|
*
|
|
* @see http://instanceof.me/post/52245507631/regex-emulate-atomic-grouping-with-lookahead
|
|
* @see http://blog.stevenlevithan.com/archives/mimic-atomic-groups
|
|
* @see https://javascript.info/regexp-infinite-backtracking-problem
|
|
*
|
|
* once browsers reliably support atomic grouping or possessive
|
|
* quantifiers natively we should remove this trick and simplify
|
|
*
|
|
* @type {RegExp}
|
|
*
|
|
* @since 3.8.0
|
|
* @since 4.6.1 added optimization to prevent backtracking on attribute parsing
