When creating a new `Makefile` target to build,
it's also necessary to update the `clean` target,
which purpose is to remove built targets when they are present.
This process is simple, but it's also easy to forget :
since there is a large distance between the position in the `Makefile` where the new built target is added,
and the place where the list of files to `clean` is defined.
Moreover, the list of files becomes pretty long over time,
hence it's difficult to visually ensure that all built targets are present there,
or that no old target (no longer produced) is no longer in the list
This PR tries to improve this process by adding a CLEAN variable.
Now, when a new built target is added to the `Makefile`,
it should preceded by :
```
CLEAN += newTarget
newTarget:
<TAB> ...recipe...
```
This new requirement is somewhat similar to `.PHONY: newTarget` for non-built targets.
This new method offers the advantage of locality :
there is no separate place in the file to maintain a list of files to clean.
This makes maintenance of `make clean` easier.
Adds documentation to help and man pages for legacy pass-through behavior
when force is set and destination is stdout. Documents --pass-through in
man pages
Fixes#3211.
Adds the `--[no-]pass-through` flag which enables/disables pass-through mode.
* `zstdcat`, `zcat`, and `gzcat` default to `--pass-through`.
Pass-through mode can be disabled by passing `--no-pass-through`.
* All other binaries default to not setting pass-through mode.
However, we preserve the legacy behavior of enabling pass-through
mode when writing to stdout with `-f` set, unless pass-through
mode is explicitly disabled with `--no-pass-through`.
Adds a new test for this behavior that should codify the behavior we want.
Fixes#3212.
Long literal and match lengths had an off-by-one error in ZSTD_getSequenceLength.
Fix the off-by-one error, and add a golden compression test that catches the bug.
Also run all the golden tests in the cli-tests framework.
When user pass in argument for both decompression and multi-thread, print a warning message
to indicate that multi-threaded decompression is not supported.
* Add warning when multi-thread decompression is requested
* add test case for multi-threaded decoding warning
Expectation is for -d -T0 we will not throw any warning,
and see warning for any other -d -T(>1) inputs
* Fixing compiler warnings
* Replace the old -s flag with the -Wl,-s flag
* Fixing compiler warnings
* Fixing the linker strip flag and tests/code not working as expected on AIX
* Intial commit to address 3090. Added support to decompress empty block
* Update zstd_decompress_block.c
Addressed review comments for the case of 'set_basic'

Streaming decompression used to wait for a minimum of 5 bytes before attempting decoding.
This meant that, in the case that only a few bytes (<5) were provided,
and assuming these bytes are incorrect,
there would be no error reported.
The streaming API would simply request more data, waiting for at least 5 bytes.
This PR makes it possible to detect incorrect Frame IDs as soon as the first byte is provided.
Fix#3169
Adopt the more standard Usage: formatting style
List short and long options alongside where available
Print lists as a table
Use command style description
Newer less versions appear to have changed how stderr
and stdout are showing error messages. hardcode the
expected behavior to make the tests pass with any less version.
Also set locale to C so that the strings are matching.
Set removeSrcFile back to false when -c or --stdout is used to improve
compatibility with gzip(1) behavior.
gzip(1) is removing the original file on compression unless --stdout or
/-c is used. zstd is defaulting to keep the file unless --rm is used or
when it is called via a gzip symlink, in which it is removing by
default. Specifying -c/--stdout turns this behavior off.
* fix the assertion in readLinesFromFile
When the file is not terminated by endline, readLineFromFile will append
a '\0' for the last line. In this case pos + lineLength == dstCapacity.
* test: don't print very long text garbage
The zstd symlinks, notably `zstdcat`, weren't working as expected
because only the `tests/cli-tests/bin/zstd` wrapper was symlinked. We
still invoked `zstd` with the name `zstd`. The fix is to create a
directory of zstd symlinks in `tests/cli-tests/bin/symlinks` for each
name that zstd recognizes. And when `tets/cli-tests/bin/zstd` is
invoked, it selects the correct symlink to call.
See the test `zstd-cli/zstdcat.sh` for an example of how it would work.
* playtests.sh: fix for a bug in macos' /bin/sh that persists temporary env vars when introduced before function calls
* cli-tests/run.py: Do not use existing ZSTD* envvars
