Yann Collet 9ae3bf5ee2 update compression results 
good news: there are only improvements
 2024-02-03 17:52:50 -08:00
Yann Collet e5af24c5fa fixed wrong assert 2024-02-03 17:48:29 -08:00
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.

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.

It cannot be an alias, because it would lock the package to use either static or shared libraries at its build time. We want to decide this at the time `find_package` is called.
