Added --output-dir-flat=
 2019-10-22 15:19:04 -07:00
Nick Terrell
b1ec94e63c Fix ZSTD_f_zstd1_magicless for small data 
* Fix `ZSTD_FRAMEHEADERSIZE_PREFIX` and `ZSTD_FRAMEHEADERSIZE_MIN` to
  take a `format` parameter, so it is impossible to get the wrong size.
* Fix the places that called `ZSTD_FRAMEHEADERSIZE_PREFIX` without
  taking the format into account, which is now impossible by design.
* Call `ZSTD_frameHeaderSize_internal()` with `dctx->format`.
* The added tests catch both bugs in `ZSTD_decompressFrame()`.

Fixes #1813.

0ee360982d improved test mode -t 
The test mode do no longer open a file `/dev/null` nor write anything to output.

This is supposed to be more efficient than writing to `/dev/null`,
and more universal too : the previous method was failing on Windows.

This resolves a race condition where zstd or unzstd may expose read
permissions beyond the original file allowed.  Mode 600 is used
temporarily during the compression and decompression write stage
and the new file inherits the original file’s mode at the end.

1e01560b83 fixed timespec_get() initialization bug on some targets 
not sure why, but msan fires an "unitialized variable" error
when time gets properly initialized by timespec_get().
Maybe in some cases, not all bytes of the structure are initialized ?
Or maybe msan fails to detect the initialization ?

Anyway, pre-initializing the variable before passing it to timespec_get() works.

885476fb5b FreeBSD_11 specific fix 
C11 mandates the definition of timespec_get() and TIME_UTC.
However, FreeBSD11 announce C11 compliance, but does not provifr timespec_get(),
breaking link stage for benchfn.
Since it does not provide TIME_UTC either, which is also required by C11,
test this macro: this will automatically rule out FreeBSD 11 for this code path
(it will use the backup C90 path instead, based on clock_t).

The issue seeems fixed in FreeBSD 12.

59a7116cc2 benchfn dependencies reduced to only timefn 
benchfn used to rely on mem.h, and util,
which in turn relied on platform.h.
Using benchfn outside of zstd required to bring all these dependencies.

Now, dependency is reduced to timefn only.
This required to create a separate timefn from util,
and rewrite benchfn and timefn to no longer need mem.h.

Separating timefn from util has a wide effect accross the code base,
as usage of time functions is widespread.
A lot of build scripts had to be updated to also include timefn.

In #1520 it is described that FreeBSD doesn't detect symbolic links. The
same is true for OpenBSD. This diff fixes this issue for OpenBSD. I'm
guessing that something similar works for FreeBSD as well. However, I'm
unable to test this.

LZ4 tests are part of the "Extended" tests on Travis CI,

Since latest cron job did not failed,
especially this one : https://travis-ci.org/facebook/zstd/jobs/484365040

4fa585aee3 fix --list on truncated files 
fseek() doesn't indicate when it moves past the end of a file.
Consequently, if a file is truncated within its last block, the error would't be detected.

This PR adds a test scenario that induces this situation using a small compressed file of only one block in size.
This test is added to tests/playTests.sh

Check is implemented by ensuring that the filehandle position is equal to the filesize upon exit.

fe82637069 Fix #1425 - Use physical core count API on FreeBSD 
Similar to Apple, use the native physical core count sysctl, when available.

This is a little repetitive (it's basically the __APPLE__ method plus the
otherBSD method concatenated together) but seemed clearer than any way that
would totally eliminate repetition.

The __FreeBSD_version check only tests the version of the FreeBSD kernel
that zstd is compiled on; importantly, it may be run on a different version.
So the compile-time check is a little naive and needs to be able to fallback
to work on older versions of FreeBSD.  For a similar reason, it may make
sense to simply eliminate the __FreeBSD_version check entirely.  The
tradeoff is that a spurious sysctlbyname would be issued when -T0 is used on
older kernels.

ae1d6bd48e fixed playTests.sh for minGW 
On Windows, the equivalent of `/dev/null` is `NUL`.
When tests are run under msys2/minGW,
the environment identifies itself as Windows,
hence the script uses `NUL` instead of `/dev/null`
but the environment will consider `NUL` to be a regular file name.
Consequently, `NUL` will be overwritten during tests,
triggering an error.

This patch uses flag `-f` to force such overwrite
passing the test.

ededcfca57 fix confusion between unsigned <-> U32 
as suggested in #1441.

generally U32 and unsigned are the same thing,
except when they are not ...

case : 32-bit compilation for MIPS (uint32_t == unsigned long)

A vast majority of transformation consists in transforming U32 into unsigned.
In rare cases, it's the other way around (typically for internal code, such as seeds).

Among a few issues this patches solves :
- some parameters were declared with type `unsigned` in *.h,
  but with type `U32` in their implementation *.c .
- some parameters have type unsigned*,
  but the caller user a pointer to U32 instead.

These fixes are useful.

However, the bulk of changes is about %u formating,
which requires unsigned type,
but generally receives U32 values instead,
often just for brevity (U32 is shorter than unsigned).
These changes are generally minor, or even annoying.

As a consequence, the amount of code changed is larger than I would expect for such a patch.

Testing is also a pain :
it requires manually modifying `mem.h`,
in order to lie about `U32`
and force it to be an `unsigned long` typically.
On a 64-bit system, this will break the equivalence unsigned == U32.
Unfortunately, it will also break a few static_assert(), controlling structure sizes.
So it also requires modifying `debug.h` to make `static_assert()` a noop.
And then reverting these changes.

So it's inconvenient, and as a consequence,
this property is currently not checked during CI tests.
Therefore, these problems can emerge again in the future.

I wonder if it is worth ensuring proper distinction of U32 != unsigned in CI tests.
It's another restriction for coding, adding more frustration during merge tests,
since most platforms don't need this distinction (hence contributor will not see it),
and while this can matter in theory, the number of platforms impacted seems minimal.

Thoughts ?
