Raimund Andree 2deec1761b fix(items): reject a -Filter of more than 32,767 characters An independent review found that a very long -Filter pattern (for example, a run of 120,000 question marks, or 45,000 asterisks) crashes the whole host process with an uncatchable StackOverflowException: the matcher recurses roughly once per character of the pattern, and a long enough pattern exhausts the stack. A pattern this long serves no purpose that a shorter one could not also serve, and the review confirmed that patterns of 32,767 characters or fewer, of any shape (literal, "?" repeated, "" repeated, "?" repeated, "*." repeated), do not come close to exhausting the stack. Added `[ValidateLength(0, 32767)]` next to the existing `[ValidateNotNull]` on -Filter, so that a pattern longer than 32,767 characters is rejected at parameter binding, before it ever reaches the matcher, with the same `ParameterArgumentValidationError` and `'Filter'` in the message as the existing null rejection; shorter values, including an empty one, are unaffected. Tests (Tests\ItemCmdlets.Tests.ps1, "Get-ChildItem2" > "Recursion, type filters, and depth"): a -Filter of 32,768 characters now gives ParameterArgumentValidationError, and one of exactly 32,767 characters ("?" repeated, in a folder with one file) returns the right result without crashing. The crash itself was confirmed in a disposable child process (not through the shared Pester harness, to avoid taking that process down too) with the reviewer's probe (C:\Temp\ntfs-rc9\review-probes-r3\p9-longpattern.ps1 -N 120000 -Kind qm): the process terminated with a StackOverflowException before this fix, and after it, the same probe at the exact boundaries (32,767 and 32,768 characters, every pattern kind the probe offers) neither crashes nor is accepted past the limit.
