TestFoundation test suite failing while building Swift Toolchain
(Adrian Prantl) #2

From the looks of it, the python bindings are either incomplete or you have some search path problem. As a starting point, I'd try importing the lldb module from within a python interpreter, and debug why that doesn't work.


#3

Hi,

I have installed all the development dependencies as mentioned in https://github.com/apple/swift:-

sudo apt-get install git cmake ninja-build clang python uuid-dev libicu-dev icu-devtools libbsd-dev libedit-dev libxml2-dev libsqlite3-dev swig libpython-dev libncurses5-dev pkg-config libblocksruntime-dev libcurl4-openssl-dev systemtap-sdt-dev tzdata rsync

I also tried setting the PYTHONPATH as mentioned in:-

The problem still persists and affects around 865 tests due to this reason.

Let me know if I am missing anything else.


(Davide C. C. Italiano) #4

Just set PYTHON_PATH to what lldb -P evaluates to.

e.g.

$ lldb -P
/Applications/Xcode3.app/Contents/SharedFrameworks/LLDB.framework/Resources/Python
$ export PYTHONPATH="/Applications/Xcode3.app/Contents/SharedFrameworks/LLDB.framework/Resources/Python"

Then open python and type
import lldb

Does that work? If not, you have an include problem. If that does, try to run some basic lldb python commands and see what happens (you can probably copy test cases bodies).


#5

Hi @dcci ,

Thanks for the above suggestion, it worked!

Set the python path environment variable PYTHONPATH to what lldb -P evaluated to:-

root@877e1c79bb05:~# /root/swift-source/build/buildbot_linux/lldb-linux-powerpc64le/bin/lldb -P
/root/swift-source/build/buildbot_linux/lldb-linux-powerpc64le/lib/python2.7/site-packages

root@877e1c79bb05:~# export PYTHONPATH="/root/swift-source/build/buildbot_linux/lldb-linux-powerpc64le/lib/python2.7/site-packages"

With this 865/883 failing test cases passed which previously failed with common errors as mentioned in previous comments above.

Current status of lldb test suite is as below:-
Expected Passes : 1402
Unsupported Tests : 49
Unexpected Failures: 127

Investigating on the failure test cases further.

Around 51 test cases fail due to the following errors:-

FAIL: test_dwarf (lldbsuite.test.lldbtest.TestArrayEnum)

Let me know if anything looks familiar to you. Thanks! :slight_smile:


(Davide C. C. Italiano) #6

Looks like the inline category of tests is broken. I haven't seen this one earlier, but I do recommend to start debugging the python code responsible for this.
(Random guess, given some breakpoints are not hit, could be that the sources aren't built with -g).


#7

Checked, sources are built with -g.


#8

Current status of lldb test suite is as below:-
Expected Passes : 1402
Unsupported Tests : 49
Unexpected Failures: 127

Many of the remaining test cases throw up errors like below:-
Error Type 1(Approx 49 occurences):-

error: Couldn't lookup symbols:
swift_beginAccess
swift_endAccess
error: Couldn't lookup symbols:
swift_allocError
swift_getWitnessTable

[...Many More...]

Error Type 2(Approx 51 occurences):-

AssertionError: False is not True : inline test did not hit a single breakpoint

Error Type 3(Approx 13 occurences):-

AssertionError: False is not True : Expected 1 thread to stop at breakpoint, 0 did.

Investigating on the failure test cases further.

Tried setting the appropriate environment variables like LD_LIBRARY_PATH, LIBRARY_PATH, PATH, etc, however they don't help much.


(Davide C. C. Italiano) #9

In my experience this happens because the REPL doesn't know how to locate libswiftCore.so/dylib.

Can you make sure the RPATH of the repl_swift binary is set up correctly?
(points to something that contains libSwiftcore ?)

To test my theory you can run lldb --repl and type print() and see if you see the errors.


#10

Hi @dcci ,

I looked around the internet and tried exporting the following environment variables with the paths containing 'libswiftCore.so' library:
LD_LIBRARY_PATH, LIBRARY_PATH, RPATH, RUNPATH, SWIFTPM_EMBED_RPATH, REPL_SWIFT_RPATH, DT_RUNPATH, DT_RPATH, DYLD_LIBRARY_PATH.

However even after setting the environment variables, I am still facing the error - "error: Couldn't lookup symbols:"

root@d75bebab716c:~# /root/swift-source/build/buildbot_linux/lldb-linux-powerpc64le/bin/lldb --repl

Am I missing anything?


(Davide C. C. Italiano) #11

Assuming you're building with Cmake, you can go in:
lldb/tools/repl/swift
and see in the CMakeList.txt file:

# Set the correct rpath to locate libswiftCore.
if (LLDB_BUILD_FRAMEWORK)
  set(CMAKE_EXE_LINKER_FLAGS "-Wl,-rpath \
      -Wl,${CMAKE_BINARY_DIR}/${LLDB_FRAMEWORK_INSTALL_DIR}/${LLDB_FRAMEWORK_RESOURCE_DIR}/Swift/macosx")
elseif( CMAKE_SYSTEM_NAME MATCHES "Linux" )
  # Set the correct rpath to locate libswiftCore
  set(CMAKE_EXE_LINKER_FLAGS "-Wl,-rpath,${CMAKE_BINARY_DIR}/../swift-linux-x86_64/lib${LLVM_LIBDIR_SUFFIX}/swift/linux -Wl,-ldl")
  set(CMAKE_INSTALL_RPATH "$ORIGIN/../lib/swift/linux:${CMAKE_INSTALL_RPATH}")
endif()

My wild guess here is that the -Wl,-rpath passed here is wrong. I would say the guess isn't that wild either, because, as you can see, the cmake bits hardcode the architecture, which doesn't match the one you're running on.

To see which RPATH is embedded in the binary generated, repl_swift, I do recommend to use readelf or objdump. BTW, if this is the issue, it would be great if we can get that fixed.


#12

Hi @dcci ,

Thanks for the inputs, I made the below changes in the CMakeList.txt:-

if (CMAKE_HOST_SYSTEM_PROCESSOR MATCHES "ppc64le")
set(CMAKE_EXE_LINKER_FLAGS "-Wl,-rpath,{CMAKE_BINARY_DIR}/../swift-linux-powerpc64le/lib{LLVM_LIBDIR_SUFFIX}/swift/linux/powerpc64le -Wl,-ldl")
else()
set(CMAKE_EXE_LINKER_FLAGS "-Wl,-rpath,{CMAKE_BINARY_DIR}/../swift-linux-x86_64/lib{LLVM_LIBDIR_SUFFIX}/swift/linux -Wl,-ldl")

With this the "error: Couldn't lookup symbols:" are no longer encountered, and the lldb test failure count has come down to 117 from earlier 127 failures.
However for tests I am still seeing errors like below:-

1.) AssertionError: False is not True : inline test did not hit a single breakpoint(51 Occurences)
2.) AssertionError: False is not True : Expected 1 thread to stop at breakpoint, 0 did.(13 Occurences)
3.) AssertionError: False is not True(39 Occurences)
4.) AssertionError: False is not True : Command 'bt
Error output:
error: invalid thread
' returns successfully
(1 Occurence)
5.) AssertionError: False is not True : Command 'frame variable -d run -- o
Error output:
error: invalid thread
' returns successfully
(1 Occurence)

Does anything look familiar or I am still missing something? :|


(Davide C. C. Italiano) #13

I see the failures went down, can you submit a patch?

For the other failures, I'm afraid I can't be of much help.
From what I see you're debugging ppcle which is a very different architecture than the one most people run on. You might consider start debugging the failures, and ask here if you get stuck.

(Simon Evans) #15

It looks like there is no libicu library, did you pass the --libicu argument to build-script to get it to build?


#16

I am using the build-toolchain script to build as below:-
./swift/utils/build-toolchain srtbundle --test

This was working fine as recently as yesterday, only failing during testing step at the lldb-suite related test suite.


(Simon Evans) #17

Maybe try deleting the build/buildbot_linux/libicu-linux-powerpc64le directory (or whatever the arch specific directory is called) and try building again, it looks to be using the buildbox_linux preset so should be included there.


#18

Thanks @spevans, I did a clean build on another system and it proceeded smoothly.


#19

Hi @dcci ,

Out of the 109 remaining lldb related test failures I am seeing the following kind of errors for 107 tests. On careful observation I found that the --arch parameter passed to the dotest.py is empty. i.e. "Command invoked: /root/swift-source/lldb/test/dotest.py -q --arch= -s /root/swift-source/build/buildbot_linux/lldb-linux-powerpc64le/lldb-test-traces".
Is this expected or this could be causing issues?

Detailed error is as below(seen for 107/109 failures):-

@spevans do you find anything familiar in the above error related to --arch parameter passed to the dotest.py being empty?
