Currently the build errors out with:
```
ERROR: This script does not work on Python 3.6 The minimum supported Python version is 3.7. Please use https://bootstrap.pypa.io/pip/3.6/get-pip.py instead.
```
While in theory this advice could be followed to get a better pip on
xenial, Meson has now deprecated python 3.6 support too, and the next
(unreleased) version requires python 3.7
There are a couple solutions to this:
- hold the version of pip, allow pip to only install 3.6-compatible
versions of meson (effectively freezing meson going forward)
- install python 3.7 on xenial
- update to a 2-year-old image instead of a 4-year-old one
Option 3 is the simplest.
This was ~30mn, by far the longest run on travisCI.
That's because it re-analyzes multiple times the same files (library files notably).
It also performs actions that make no sense for the static analyzer purpose,
such as building the single-file library.
Reduced time spent in this test by reducing its scope :
just build the CLI, and obviously the library along it.
These are the only ones that really deserve to be analyzed.
Unfortunately, it still results in a number of false positives when using newer versions of scanbuild
(each version of scanbuild generates a different list of false positives).
These will have to be fixed before transfering to Github Actions.
fix#2045
When compiling `libzstd` in multithreading mode,
the `libzstd-mt` recipe would not include `-pthread`,
resulting in an underlinked dynamic library.
Added a test on Travis to check that the library is fully linked.
This makes it possible, in some future release,
to build a multi-threaded `libzstd` dynamic library by default
as it would no longer impact the build script of user programs.
* Removing symbols that are not being tested
* Removing symbols used in zstdcli, fileio, dibio and benchzstd
* Removing symbols used in zbuff and add test-zbuff to travis
* Removing remaining symbols and adding unit tests instead
* Removing symbols test entirely
* Initial revised automated benchmarking script
* Updating nb_iterations and making loop infinite
* Allowing benchmarking params to be changed from cli
* Renaming old speed test
* Removing numpy dependency for cli
* Change filename and benchmakr on pr level
* Moving build outside loop and adding iterations param
* Moving benchmarking to seperate travis ci test
* Fixing typo and using unused variable
* Added mode labels and updated README accordingly
* Adding new mode 'current' that compraes facebook:dev against current hash
* Typo
* Reverting previous accidental diff
* Typo
* Adding frequency config variable to prevent github from blacklisting
* Added new argument for frequency of fetching new prs
* Updating documentation
- only compiles zstd CLI
- enforces zero warning tolerance policy
note : mingw compilation of the library complains (warning) about -fPIC flag.
It mostly ignores it, so it's not a big issue.
Still, it would need to be fixed if library cross-compilation becomes part of CI.
At this stage, it's unclear if this is a scenario.
/dev/null permissions were modified when using sudo rights.
This fixes this bug during decompression.
More importantly, this patch adds a test, triggered in TravisCI,
ensuring unaltered /dev/null permissions.
