But this magic number had been duplicated. Urgh! The result is that adhoc-revtuple-generator might generate a weirdly truncated output which causes cs-bisection-stop to fail with messages like this: *** not RelvUp at 3d40147282670d597b336be5599b5cc4c2ff7ddd at ./cs-bisec= tion-step line 554. *** not RelvDown at 2fa3479cfadb0bb3fe694dbfd29f2350eb2570df at ./cs-bis= ection-step line 554. *** not RelvUp at 2fa3479cfadb0bb3fe694dbfd29f2350eb2570df at ./cs-bisec= tion-step line 554. ... Use of uninitialized value in concatenation (.) or string at ./cs-bisecti= on-step line 747. Should test . BROKEN see earlier errors. at ./cs-bisection-step line 1454, line = 10089. Fix this by (i) plumbing the magic value we already edited properly back to the (command-line controlled) global variable (ii) changing the global variable from 1000 to 5000. git-grep '\b1000\b' still produces a fair amount of output but most of it is timeouts, which is fair enough. There is also a flight count limit in sg-report-flight, which limits how far back it is willing to look. We don't want to change that here. With this change, cs-bisection-step on the currently-failing freebsd build job does this: Searching for interesting versions Result found: flight 141420 (pass), for basis pass Result found: flight 143397 (fail), for basis failure Need to reproduce basis pass (pass); had 1 already. Should test 2fa3479cfadb0bb3fe694dbfd29f2350eb2570df. This looks plausible: it is picking up where it left off before the basis pass fell over its horizon.
