# Maintenance Schedule
`ubuntu-16.04` environment will be removed at September, 2021.
--------------------------------------------------------------
It also will remove test for the following compilers:
- gcc: 4.4, 4.6, 4.7
- clang: 3.5, 3.6, 3.7, 3.8
See also GitHub official announcement :
["Ubuntu 16.04 LTS will be removed on September 20, 2021"](https://github.blog/changelog/2021-04-29-github-actions-ubuntu-16-04-lts-virtual-environment-will-be-removed-on-september-20-2021/).
# Difference with `.travis.yml`
The following tests are not included yet.
- name: Compile OSS-Fuzz targets
- name: tag build
- name: aarch64 real-hw tests
- name: PPC64LE real-hw tests
- name: IBM s390x real-hw tests
# Known issues
## USAN, ASAN (`lz4-ubsan-x64`, `lz4-ubsan-x86`, `lz4-asan-x64`)
For now, `lz4-ubsan-*` ignores the exit code of `make usan` and `make usan32`.
Because there're several issues which may take relatively long time to resolve.
We'll fully enable it when we ensure `make usan` is ready for all commits and PRs.
See https://github.com/lz4/lz4/pull/983 for details.
## C Compilers (`lz4-c-compilers`)
- Our test doesn't use `gcc-4.5` due to installation issue of its package. (`apt-get install gcc-4.5` fails on GH-Actions VM)
- Currently, the following 32bit executable tests fail with all versions of `clang`.
- `CC=clang-X CFLAGS='-O3' make V=1 -C tests clean test-lz4c32`
- `CC=clang-X CFLAGS='-O3 -mx32' make V=1 -C tests clean test-lz4c32`
- See [#991](https://github.com/lz4/lz4/issues/991) for details.
- Currently, the following 32bit executable tests fail with `gcc-11`
- `CC=clang-X CFLAGS='-O3' make V=1 -C tests clean test-lz4c32`
- `CC=clang-X CFLAGS='-O3 -mx32' make V=1 -C tests clean test-lz4c32`
## cppcheck.yml
This test script ignores the exit code of `make cppcheck`.
Because this project doesn't 100% follow their recommendation.
Also sometimes it reports false positives.
