If WebKit is built with code coverage instrumentation enabled, that pushes us over the troublesome threshold, and WebKit sometimes fails to launch its child processes. Provide a build-time option to add a retry loop for such launches, which enables us to run test suites even if coverage is enabled. Unless the make command line contains GCC_PREPROCESSOR_ADDITIONS=ENABLE_RETRY_LAUNCHES, or that option is specified in some other way, this code change has no effect. 2200174 1 adrian_taylor 2026-04-14 06:28:27 -0700 Pull request: https://github.com/WebKit/WebKit/pull/62729 2200526 2 ews-feeder 2026-04-14 23:37:54 -0700 Committed 311264@main (8c1776bc8803): <https://commits.webkit.org/311264@main> Reviewed commits have been landed.
