--------------------------------------
Summary: [Python][Packaging] Manylinux1/2010 complience issue with
libz
Key: ARROW-5886
URL: https://issues.apache.org/jira/browse/ARROW-5886
Project: Apache Arrow
Issue Type: Bug
Components: Packaging, Python
Affects Versions: 0.14.0
Reporter: Krisztian Szucs
So we statically link liblz4 in the manylinux1 wheels
{code}
# ldd pyarrow-manylinux1/libarrow.so.14 | grep z
libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007fc28cef4000)
{code}
but dynamically in the manylinux2010 wheels
{code}
# ldd pyarrow-manylinux2010/libarrow.so.14 | grep z
liblz4.so.1 => not found (already deleted to reproduce the issue)
libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007f56f7440000)
{code}
this what this PR resolves.
What I'm finding strange, that auditwheel seems to bundle libz for manylinux1:
{code}
# ls -lah pyarrow-manylinux1/*z*so.*
-rwxr-xr-x 1 root root 115K Jun 29 00:14
pyarrow-manylinux1/libz-7f57503f.so.1.2.11
{code}
while ldd still uses the system libz:
{code}
# ldd pyarrow-manylinux1/libarrow.so.14 | grep z
libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007f91fcf3f000)
{code}
For manylinux2010 we also have liblz4:
{code}
# ls -lah pyarrow-manylinux2010/*z*so.*
-rwxr-xr-x 1 root root 191K Jun 28 23:38
pyarrow-manylinux2010/liblz4-8cb8bdde.so.1.8.3
-rwxr-xr-x 1 root root 115K Jun 28 23:38
pyarrow-manylinux2010/libz-c69b9943.so.1.2.11
{code}
and ldd similarly tries to load the system libs:
{code}
# ldd pyarrow-manylinux2010/libarrow.so.14 | grep z
liblz4.so.1 => not found
libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007fd72764e000)
{code}
Inspecting manylinux1 with `LD_DEBUG=files,libs ldd libarrow.so.14` it seems
like to search the right path, but cannot find the hashed version of libz
`libz-7f57503f.so.1.2.11`
{code}
463: file=libz.so.1 [0]; needed by ./libarrow.so.14 [0]
463: find library=libz.so.1 [0]; searching
463: search path=/tmp/pyarrow-manylinux1/. (RPATH from
file ./libarrow.so.14)
463: trying file=/tmp/pyarrow-manylinux1/./libz.so.1
463: search cache=/etc/ld.so.cache
463: trying file=/lib/x86_64-linux-gnu/libz.so.1
{code}
There is no `libz.so.1` just `libz-7f57503f.so.1.2.11`.
Similarly for manylinux2010 and libz:
{code}
470: file=libz.so.1 [0]; needed by ./libarrow.so.14 [0]
470: find library=libz.so.1 [0]; searching
470: search path=/tmp/pyarrow-manylinux2010/. (RPATH
from file ./libarrow.so.14)
470: trying file=/tmp/pyarrow-manylinux2010/./libz.so.1
470: search cache=/etc/ld.so.cache
470: trying file=/lib/x86_64-linux-gnu/libz.so.1
{code}
for liblz4 (again, I've deleted the system one):
{code}
470: file=liblz4.so.1 [0]; needed by ./libarrow.so.14 [0]
470: find library=liblz4.so.1 [0]; searching
470: search path=/tmp/pyarrow-manylinux2010/. (RPATH
from file ./libarrow.so.14)
470: trying file=/tmp/pyarrow-manylinux2010/./liblz4.so.1
470: search cache=/etc/ld.so.cache
470: search
path=/lib/x86_64-linux-gnu/tls/x86_64:/lib/x86_64-linux-gnu/tls:/lib/x86_64-linux-gnu/x86_64:/lib/x86_64-linux-gnu:/usr/lib/x86_64-linux-gnu/tls/x86_64:/usr/lib/x86_64-linux-gnu/tls:/usr/lib/x86_64-linux-gnu/x86_6$

(system search path)
{code}
There are no `libz.so.1` nor `liblz4.so.1`, just `libz-c69b9943.so.1.2.11` and
`liblz4-8cb8bdde.so.1.8.3`
According to https://www.python.org/dev/peps/pep-0571/ `liblz4` nor `libz` are
part of the whitelist, and while these are bundled with the wheel, seemingly
cannot be found - perhaps because of the hash in the library name?
I've tried to inspect the wheels with `auditwheel show` with version `2` and
`1.10`, both says the following:
{code}
# auditwheel show pyarrow-0.14.0-cp37-cp37m-manylinux2010_x86_64.whl
pyarrow-0.14.0-cp37-cp37m-manylinux2010_x86_64.whl is consistent with
the following platform tag: "linux_x86_64".
The wheel references external versioned symbols in these system-
provided shared libraries: libgcc_s.so.1 with versions {'GCC_3.3',
'GCC_3.4', 'GCC_3.0'}, libpthread.so.0 with versions {'GLIBC_2.3.3',
'GLIBC_2.12', 'GLIBC_2.2.5', 'GLIBC_2.3.2'}, libc.so.6 with versions
{'GLIBC_2.4', 'GLIBC_2.6', 'GLIBC_2.2.5', 'GLIBC_2.7', 'GLIBC_2.3.4',
'GLIBC_2.3.2', 'GLIBC_2.3'}, libstdc++.so.6 with versions
{'CXXABI_1.3', 'GLIBCXX_3.4.10', 'GLIBCXX_3.4.9', 'GLIBCXX_3.4.11',
'GLIBCXX_3.4.5', 'GLIBCXX_3.4', 'CXXABI_1.3.2', 'CXXABI_1.3.3'},
librt.so.1 with versions {'GLIBC_2.2.5'}, libm.so.6 with versions
{'GLIBC_2.2.5'}, libdl.so.2 with versions {'GLIBC_2.2.5'}, libz.so.1
with versions {'ZLIB_1.2.0'}
This constrains the platform tag to "manylinux2010_x86_64". In order
to achieve a more compatible tag, you would need to recompile a new
wheel from source on a system with earlier versions of these
libraries, such as a recent manylinux image.
{code}
{code}
# auditwheel show pyarrow-0.14.0-cp37-cp37m-manylinux1_x86_64.whl
pyarrow-0.14.0-cp37-cp37m-manylinux1_x86_64.whl is consistent with the
following platform tag: "linux_x86_64".
The wheel references external versioned symbols in these system-
provided shared libraries: libgcc_s.so.1 with versions {'GCC_3.4',
'GCC_3.0', 'GCC_3.3'}, libc.so.6 with versions {'GLIBC_2.3',
'GLIBC_2.2.5', 'GLIBC_2.3.4', 'GLIBC_2.4', 'GLIBC_2.3.2'},
libstdc++.so.6 with versions {'CXXABI_1.3', 'GLIBCXX_3.4.5',
'GLIBCXX_3.4'}, librt.so.1 with versions {'GLIBC_2.2.5'}, libm.so.6
with versions {'GLIBC_2.2.5'}, libpthread.so.0 with versions
{'GLIBC_2.3.3', 'GLIBC_2.3.2', 'GLIBC_2.2.5'}, libdl.so.2 with
versions {'GLIBC_2.2.5'}, libz.so.1 with versions {'ZLIB_1.2.0'}
The following external shared libraries are required by the wheel:
{
"libc.so.6": "/lib/x86_64-linux-gnu/libc-2.24.so",
"libcrypt.so.1": "/lib/x86_64-linux-gnu/libcrypt-2.24.so",
"libdl.so.2": "/lib/x86_64-linux-gnu/libdl-2.24.so",
"libgcc_s.so.1": "/lib/x86_64-linux-gnu/libgcc_s.so.1",
"libm.so.6": "/lib/x86_64-linux-gnu/libm-2.24.so",
"libnsl.so.1": "/lib/x86_64-linux-gnu/libnsl-2.24.so",
"libpthread.so.0": "/lib/x86_64-linux-gnu/libpthread-2.24.so",
"librt.so.1": "/lib/x86_64-linux-gnu/librt-2.24.so",
"libstdc++.so.6": "/usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.22",
"libutil.so.1": "/lib/x86_64-linux-gnu/libutil-2.24.so",
"libz.so.1": "/lib/x86_64-linux-gnu/libz.so.1.2.8"
}
In order to achieve the tag platform tag "manylinux2010_x86_64" the
following shared library dependencies will need to be eliminated:
libz.so.1
In order to achieve the tag platform tag "manylinux1_x86_64" the
following shared library dependencies will need to be eliminated:
libz.so.1
{code}
I think there are more todo left with the wheels. IMO the manylinux1 wheels are
not compliant because of `libz` and the manylinux2010 wheels are not compliant
because of both `libz` and `liblz4` (but incorrectly reported by auditwheel?).
We also need to ensure to run {{auditwheel show}} on the produced wheels in the
manylinux-test script
