short-tests-0 were silently failing. I think because of the && make clean construction. Switch to ; instead.
Also fix all the test failures that were exposed.
`make all` is failing on CircleCI because it is missing Docker. Move that test
to GitHub actions, and switch the pedantic CircleCI test to `make allmost`.
51 MB seems excessive for CI storate and considering the nature of the test.
(note : maybe we should consider using `/tmp` for files generated during tests,
as tmpfs is typically using RAM, thus preserving storage.)
Tests that libzstd.so doesn't have the exec-stack bit set using
readelf. If the stack is marked executable systemd will refuse
to link against zstd. We now test that it isn't set on every PR.
Adds a test for PR #2857
Fixes Issue #2865
Allow the `dictContentSize` to be any size. The finalized dictionary
content size must be at least as large as the maximum repcode (8). So we
add zero bytes to the dictionary to ensure that we meet that
requirement.
I've removed this restriction because its been causing us headaches when
people complain that dictionary training failed. It fails because there
isn't enough useful content to put in the dictionary. Either because
every sample is exactly the same and less than ZDICT_CONTENTSIZE_MIN bytes,
or there isn't enough content. Instead, we should succeed in creating
the dictionary, and it is up to the user to decide if it is worthwhile.
It is possible that the tables alone provide enough value.
NOTE: This allows us to produce dictionaries with finalized
`dictContentSize < ZDICT_CONTENTSIZE_MIN`. But, they are still valid
zstd dictionaries. We could remove the `ZDICT_CONTENTSIZE_MIN` macro,
but I've decided to leave that for now, so we don't break users.
Fix underflow of `nbCompares` by switching to an `int` and comparing
`nbCompares > 0`. This is a minimal fix, because I don't want to change
the logic. These loops seem to be doing `nbCompares + 1` comparisons.
The bug was reported by Dan Carpenter and found by Smatch static
checker.

* Extract out common portion of `lib/Makefile` into `lib/libzstd.mk`.
Most relevantly, the way we find library files.
* Use `lib/libzstd.mk` in the other Makefiles instead of repeating the
same code.
* Add a test `tests/test-variants.sh` that checks that the builds of
`make -C programs allVariants` are correct, and run it in Actions.
* Adds support for ASM files in the CMake build.
The Meson build is not updated because it lists every file in zstd,
and supports ASM off the bat, so the Huffman ASM commit will just add
the ASM file to the list.
The Visual Studios build is not updated because I'm not adding ASM
support to Visual Studios yet.
better for large files, and sources with relatively "stable" entropy,
like silesia.tar.
slightly worse for files with rapidly changing entropy,
like Calgary.tar/.
Updated small files tests in fuzzer
As a library, the default shouldn't be to write anything on console.
`cover` and `fastcover` have a `g_displayLevel` variable to control this behavior.
It's now set to 0 (no display) by default.
Setting notification to a higher level should be an explicit operation by a console application.
It's a bit strange, because this is hitting the dictionary special case where
the dictionary is contiguous with the input and still runs in the single-
segment path.
We should probably change that to hit the `extDict` path instead?
