* It couldn't detect that the `fastCoverParams` can't be non-null, since it was just an assertion.
* It thought we were accesing `wksp->dtable` beyond the bounds because we were using it to set the `workSpace` value. Instead, compute the workspace size used in a different way.
The option `--auto-threads` should still be accepted and parsed, even if
`ZSTD_MULTITHREAD` is not defined. It doesn't mean anything, but we
should still accept the option. Since we want scripts to be able to work
generically.
This bug was caught by tests I added to the new testing framework.
Passing 0 inputs to `DiB_shuffle()` caused an assertion failure where
it should just return.
A test is added in a later commit, with the initial introduction of the
new testing framework.
Fixes#3007.
Knowing the version of zlib/lz4/lzma we're linking against is very
useful for debugging issues with those libraries, so print it out in the
verbosity 4 version output.
Also print this information at the top of `playTests.sh`.
-r on empty directory resulted in zstd waiting input from stdin. now zstd exits without error and prints a warning message explaining why no processing happened (no files or directories to process).
* Refactored fileio.c:
- Extracted asyncio code to fileio_asyncio.c/.h
- Moved type definitions to fileio_types.h
- Moved common macro definitions needed by both fileio.c and fileio_asyncio.c to fileio_common.h
* Bugfix - rename fileio_asycio to fileio_asyncio
* Added copyrights & license to new files
* CR fixes
* Async IO decompression:
- Added --[no-]asyncio flag for CLI decompression.
- Replaced dstBuffer in decompression with a pool of write jobs.
- Added an ability to execute write jobs in a separate thread.
- Added an ability to wait (join) on all jobs in a thread pool (queued and running).
When decompressing with `-q` and an output file, the progress bar was mistakenly printed. This is a minimal fix, with a larger refactor to be stacked on top of it.
Fixes#2967.
xxHash symbols are present in `libzstd.so`, but they are local and therefore
unavailable outside the lib. There are two possible solutions to the problem.
We could make those symbols global, or we could remove the dependency.
This commit chooses the latter approach. I suppose this comes at the cost of
code size / build time. I'm open to comments on whether this is a good thing
to do, especially since this will apply even when we are statically linking
everything.
I hadn't seen #2890, so I wrote my own version. I like this approach a little
better, since it does an explicit check for a regular file, rather than
passing a magic value.
Addresses #2874.
