Yann Collet 8168a451e5 minor optimization, mostly for clarity 2024-02-03 17:26:47 -08:00
Yann Collet d31018e223 finally, a version that generalizes well 
While it's not always strictly a win,
it's a win for files that see a noticeably compression ratio increase,
while it's a very small noise for other files.

Downside is, this patch is less efficient for 32-bit arrays of integer
than the previous patch which was introducing losses for other files,
but it's still a net improvement on this scenario.

Yann Collet 0166b2ba80 modification: differentiate literal update at pos+1 
helps when litlen==1 is cheaper than litlen==0

works great on pathological arr[u32] examples
but doesn't generalize well on other files.

silesia/x-ray is amoung the most negatively affected ones.

Yann Collet de10f56be2 improve high compression ratio for file like #3793 
this works great for 32-bit arrays,
notably the synthetic ones, with extreme regularity,
unfortunately, it's not universal,
and in some cases, it's a loss.
Crucially, on average, it's a loss on silesia.
The most negatively impacted file is x-ray.
It deserves an investigation before suggesting it as an evolution.

Yann Collet 3ce4c6e046 fix Visual Studio solutions 
note: we probably don't want to maintain VS2008 solution anymore.
Its successor VS2010 is > 10 years old,
which is more or less the limit after which we can stop supporting old compilers.

Yann Collet d0b7da30e2 add a lorem ipsum generator 
this generator replaces the statistical generator
for the general case when no statistic is requested.

Generated data features a compression level speed / ratio curve
which is more in line with expectation.

Yann ColletandGitHub 1a860c8737 Merge pull request #3877 from facebook/oldgrep 
minor: playTests.sh more compatible with older versions of grep
 2024-01-21 11:31:58 -08:00
Yann Collet 81f444f4f9 made playTests.sh more compatible with older versions of grep 
replaced `\+` by `*`.
`\+` means `[1-N]`,
while `*` means `[0-N]`,
so it's not strictly equivalent
but `\+` happens to be badly supported on some flavors of grep,
and for the purpose of these tests, `*` is good enough.

Yann Collet e6f4b46493 playTests.sh does no longer needs grep -E 
it makes the test script more portable across posix systems
because `grep -E` is not guaranteed
while `grep` is fairly common.

Eli Schwartz 923cf3dc92 CI: meson: use builtin handling for MSVC 
This avoids downloading -- and periodically bumping the checksum for --
a third-party action that isn't strictly required, and thus helps keep
down dependencies and reduce update churn.
