[runtime] Initialize the output directory for crash reports before loading CoreCLR. Fixes #25820 by rolfbjarne · Pull Request #25823 · dotnet/macios

rolfbjarne · 2026-06-25T16:43:47Z

CoreCLR can write crash reports to a configurable directory via the DOTNET_CrashReportRootPath environment variable. This PR sets that variable before coreclr_initialize is called, pointing it at <NSCachesDirectory> -- a writable location that is not backed up by iCloud.

A new xamarin_is_sandboxed() helper detects whether the current process is sandboxed by querying the com.apple.security.app-sandbox entitlement via SecTaskCopyValueForEntitlement. On iOS/tvOS it returns true unconditionally. For non-sandboxed desktop apps (macOS, Mac Catalyst), the bundle identifier is appended to the caches path so each app gets its own directory.

Fixes #25820

…ading CoreCLR. Set DOTNET_CrashReportRootPath to <NSCachesDirectory> before calling coreclr_initialize, so that CoreCLR knows where to write crash reports. A new xamarin_is_sandboxed() function detects whether the app is sandboxed: - On iOS/tvOS it returns true unconditionally (always sandboxed). - On macOS/Mac Catalyst it queries the com.apple.security.app-sandbox entitlement using SecTaskCopyValueForEntitlement. For non-sandboxed apps, the bundle identifier is appended to the caches path to keep the directory app-specific (sandboxed apps already get an app-specific caches directory from the OS). The environment variable is not overwritten if already set. Fixes #25820 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
