* 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
The use of --long alters the window size internally in the underlying
library (lib/compress/zstd_compress.c:ZSTD_getCParamsFromCCtxParams),
which changes the memory required for decompression. This means that the
reported requirement from the zstd binary when -vv is specified is
incorrect.
A full fix for this would be to add an API call to be able to retrieve
the required decompression memory from the library, but as a
lighterweight fix we can just take account of the fact we've enabled
long mode and update our verbose output appropriately.
Fixes#2968
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`.
* 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.
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.
With small enough input files, the inferred value of fileWindowLog could
be smaller than ZSTD_WINDOWLOG_MIN.
This can be reproduced like so:
$ echo abc > small
$ echo abcdef > small2
$ zstd --patch-from small small2 -o patch
previously, this would fail with the error "zstd: error 11 : Parameter is out of bound"
`open()`'s mode bits are only applied to files that are created by the call.
If the output file already exists, but is not readable, the `fopen()` would
fail, preventing us from removing it, which would mean that the file would
not end up with the correct permission bits.
It's not clear to me why the `fopen()` is there at all. `UTIL_isRegularFile()`
should be sufficient, AFAICT.
