Description

I tried running tests (OS X 10.11.3), but I get a lot of "LEAKED" errors:

Component: Other → Test Suite
Operating System: All → Mac OS X

There's more than just leak-related failures in there.

Do the tests pass without valgrind, e.g.: 

make check VALGRIND=

comment:2 by German M. Bravo, 9 years ago

Nope, that won't compile. it says: 

harness/backendmanager.cc:28:11: fatal error: 'valgrind/memcheck.h' file not found
# include <valgrind/memcheck.h>

comment:3 by Olly Betts, 9 years ago

Version: → git master

Kronuz said on IRC that "I did make clean and then that make check VALGRIND=". While I'm not entirely sure why that would cause a failure to find the valgrind header, what I hoping to try was just running make check VALGRIND= after make check had failed as above.

What I'm particularly wanting to see is if disabling use of valgrind when running the tests fixes the sortableserialise1 failure.

The symbols dyld is failing to find look suspiciously like the ones you changed in an ABI incompatible way in the patch for #711 - are you perhaps trying to run tests built against a stock libxapian but actually using your patched build at run-time?

I've verified this, tests are all working is OS X when I disable Valgrind.

comment:5 by Olly Betts, 9 years ago

Resolution: invalid
Status: closed → reopened
Summary: Tests in OS X fail → valgrind leak checking false positives on OS X

The most recent valgrind release seems to be 3.11.0:

​http://valgrind.org/docs/manual/dist.news.html

which apparently has preliminary support for OS X 10.11:

There is also preliminary support for X86/MacOSX 10.11, AMD64/MacOSX 10.11 and TILEGX/Linux.

So perhaps problems are to be expected.

My guess is that the suppressions file probably needs to be updated for each OS X release - this blog post talks about needing to create your own for 10.10:

​http://kalapun.com/posts/checking-c-code-with-valgrind-on-yosemite/

I think it's worth having an open ticket for the issue that valgrind leak checking can give false positives on recent OS X versions - it's something we should at least document, and ideally workaround - e.g. by providing a suppressions file (if there's one in valgrind's VCS we can probably just use that), or by disabling leak checking automatically.

Cc: James Aylett added
Summary: valgrind leak checking false positives on OS X → valgrind leak checking false positives on OS X 10.11

Looking through the currently open bugs blocking that valgrind bug, I no longer see any leak checking ones open.

Can someone with OS X 10.11 check if the testsuite now passes under valgrind? If it does, what valgrind version are you using?

comment:8 by James Aylett, 8 years ago

So valgrind hasn't released a new version…under 3.11.0 I'm seeing qp_range3 on remotetcp_chert fails (which it doesn't do normally), and sortableserialise1 fail still (same error). Plus some leaks. 

Running test: qp_range3... QueryParserError: Unknown range operation           
Query: -10..-10
Query: -10..-9.5
Query: -10..-9
Query: -10..-8.5

Running make check VALGRIND= passes everything.

comment:9 by Olly Betts, 8 years ago

Valgrind 3.12 is now out and has "preliminary support for X86/MacOSX 10.11/12, AMD64/MacOSX 10.11/12": ​http://valgrind.org/docs/manual/dist.news.html

But no useful action shows up on ​https://bugs.kde.org/show_bug.cgi?id=348909 and nothing in the changelog for 3.12 seems to match the issues we're seeing.

comment:10 by Olly Betts, 7 years ago

Valgrind 3.13 is now out and "Preliminary support for MacOS 10.12 (Sierra) has been added."

How does the testsuite now look with valgrind on 10.11 and/or 10.12?

comment:11 by Olly Betts, 6 years ago

Using travis-ci (by just adding valgrind to the list of homebrew packages to install) I tested on macOS 10.13.3 with valgrind 3.14.0 and there are multiple issues reported for the first testcase tried (which is not a complex testcase):

It seems that valgrind support for recent macOS is too poor to be automatically enabling, and this isn't some transient situation as it seems to have been problematic for close to 3 years, perhaps more.

I'm thinking we should just adjust configure.ac so that on macOS the default is to not use valgrind (and people can use ./configure VALGRIND=valgrind if the really want to enable it).

Perhaps we should change that default for all platforms - ubsan and asan cover much of what valgrind can do with significantly less overhead. It's annoying that memsan is hard to use for C++ code (you need to recompile the standard C library with memsan for it to work usefully). The main thing we get with valgrind alone is per test-case leak checking due to integration into our test harness. Most such leaks will be the same on macOS and Linux at least.

I got travis to try with valgrind on all the macOS versions they support.

Both 10.13.3 and 10.12.6 fail with valgrind errors. On 10.10 the build times out (but travis warns that's deprecated and will be removed in "January 2019" - it's now March!)

Given it doesn't seem to work on any macOS version and that nobody's argued against it, I'm going to look at disabling automatic use of VALGRIND on macOS as I proposed earlier.
