SR-12932 Custom toolchain picks up wrong target based on iOS deployment target

Issue Description:

Setting a breakpoint in an empty iOS app's view controller's viewDidLoad method logs the following to the console:

note: This error message is displayed only once. If the error displayed above is due to conflicting search paths to Clang modules in different images of the debugged executable, this can slow down debugging of Swift code significantly, since a fresh Swift context has to be created every time a conflict is encountered.

jingham@apple.com (JIRA User), @dcci, are we getting the wrong target somehow?

swift-ci · 2019-05-15T19:20:19Z

Comment by Jim Ingham (JIRA)

It does look like we think this is a macOS not an iOSSimulator binary. @adrian-prantl might have better guesses how that might happen...

adrian-prantl · 2019-05-17T00:17:24Z

What's the output of

`(lldb) image list -t -f`

?

Also, can you capture a types log by putting

`lldb log enable types -f /tmp/types.log`

into ~/.lldbinit-Xcode and restarting Xcode and reproducing the issue?

jpsim · 2019-05-17T16:53:13Z

I've attached the output of running image list -t -f both with and without the logging line to capture the types log you asked me to add to ~/.lldbinit-Xcode.

No file at /tmp/types.log was created either during the Xcode session or after. I'm not sure if that's what you expected.

Were you not able to reproduce this issue @adrian-prantl? It may be more practical to get you to reproduce the problem so you can debug in depth, otherwise we might be playing a very inefficient game of debug telephone back and forth.

I've attached a basic iOS app Xcode project that reproduces the problems for me with a breakpoint set on the super.viewDidLoad() line.

LLDBNoContextRepro.tar.gz

adrian-prantl · 2019-05-17T16:55:54Z

> [ 0] x86_64--

Interesting: your application doesn't have a definitive operating system (in the sense of: LLDB doesn't properly detect it).

> Were you not able to reproduce this issue

Unfortunately, no, but I tried to reproduce it with my latest local build, not with a dowloaded toolchain. I will try that next. Thanks a lot for the project!

adrian-prantl · 2019-05-17T16:56:40Z

@swift-ci create

adrian-prantl · 2019-05-17T16:57:24Z

Could you please also attach the /tmp/types.log file you created?

jpsim · 2019-05-17T17:00:33Z

No file at /tmp/types.log was created either during the Xcode session or after. I'm not sure if that's what you expected.

adrian-prantl · 2019-05-17T17:02:45Z

Sorry

`lldb log enable types -f /tmp/types.log`

should have been

`log enable lldb types -f /tmp/types.log`

jpsim · 2019-05-17T17:07:46Z

Thanks that worked. Attached the log.

I tried now with 10E1001 + swift-5.1-DEVELOPMENT-SNAPSHOT-2019-05-09-a-osx.pkg and I still can't reproduce this...

Would you be able to do another run, this time with

settings set target.process.extra-startup-command QSetLogging:bitmask=LOG_RNB_REMOTE;
log enable gdb-remote all -f /tmp/packets.log

in your .lldbinit-Xcode ?

jpsim · 2019-05-22T04:31:05Z

Done, I've uploaded packets.log.tgz

Thank you. debugserver does report the platform correctly as ios-12.2:

<171430> read packet: ${"images":[{"load_address":4309229568,"mod_date":0,"pathname":"/Users/jsimard/Library/Developer/CoreSimulator/Devices/8FAE9403-9A71-45BE-9EDB-75838D23D3DD/data/Containers/Bundle/Application/5F2FF041-8231-4594-9DFD-238CF3EE4B7C/LLDBNoContextRepro.app/LLDBNoContextRepro","uuid":"AAAE4344-3865-3E8E-969E-D68067F4B686","min_version_os_name":"ios","min_version_os_sdk":"12.2","mach_header":{"magic":4277009103,"cputype":16777223,"cpusubtype":3,"filetype":2,"flags":2097285}],"segments":[{"name":"_PAGEZERO","vmaddr":0,"vmsize":4294967296,"fileoff":0,"filesize":0,"maxprot":0}],{"name":"_TEXT","vmaddr":4294967296,"vmsize":20480,"fileoff":0,"filesize":20480,"maxprot":7}],

So without having a way to reproduce this, I'll see if I can read the source code to figure out why this:

SwiftASTContext("LLDBNoContextRepro")::SetTriple("x86_64-apple-ios12.2-simulator") setting to "x86_64-apple-ios12.2-simulator"

isn't getting picked up here:

SwiftASTContext("LLDBNoContextRepro")::LogConfiguration(SwiftASTContext*)0x7fa811d0a7e0:
Architecture : x86_64--macosx

This should be addressed by the simulator triple fixes in SR-12932. If it still doesn't work, please let me know!
