From ec6a34e2a781fcfc6fe1d30e7cd358fb779157cf Mon Sep 17 00:00:00 2001 From: Jonas Devlieghere Date: Fri, 17 Nov 2023 08:00:07 -0800 Subject: [PATCH] [lldb] Pass important options to dsymForUUID (#72669) On macOS, we usually use the DebugSymbols framework to find dSYMs, but we have a few places (including crashlog.py) that calls out directly to dsymForUUID. Currently, this invocation is missing two important options: * `--ignoreNegativeCache`: Poor network connectivity or lack of VPN can lead to a negative cache hit. Avoiding those issues is worth the penalty of skipping these caches. * `--copyExecutable`: Ensure we copy the executable as it might not be available at its original location. rdar://118480731 --- lldb/examples/python/crashlog.py | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/lldb/examples/python/crashlog.py b/lldb/examples/python/crashlog.py index cb8008419404..9e4f94264037 100755 --- a/lldb/examples/python/crashlog.py +++ b/lldb/examples/python/crashlog.py @@ -356,7 +356,11 @@ class CrashLog(symbolication.Symbolicator): # Keep track of unresolved source paths. unavailable_source_paths = set() if os.path.exists(self.dsymForUUIDBinary): - dsym_for_uuid_command = "%s %s" % (self.dsymForUUIDBinary, uuid_str) + dsym_for_uuid_command = ( + "{} --copyExecutable --ignoreNegativeCache {}".format( + self.dsymForUUIDBinary, uuid_str + ) + ) s = subprocess.check_output(dsym_for_uuid_command, shell=True) if s: try:
