This behavior has been preserved for compatibility with existing ecosystem.
But it's problematic, as some environment start `lz4` without identifying stdout as console by default,
leading to a change of behavior for a same line of script.
A more sensible policy would be to default to stdout only when input is stdin.
Soft change for the time being : keep the behavior, just print a warning message.
User should prefer `-c` to explicitly select `stdout`.
Also : updated tests in Makefile to explicitly select `stdout` with `-c`.
This is the reverse of `-BD`, and the current default.
This command can be useful to reverse a previous `-BD` command.
It may in the future be more important
if `lz4` switches to generating dependent blocks by default.
make a round trip test with arbitrary input file,
generate an `abort()` on error,
to work in tandem with `afl`.
note : currently locked on level 9, to investigate #560.
* Uninstall didn't remove the pkg-config correctly.
* Fix `mandir`
* Allow overriding either upper- or lower-case location variables, but
always use the lower case variables.
* Add test case that ensures overriding both upper- and lower-case
variables is the same, and that the directory is empty after uninstall.
When run with `-jN`, the `rm tmp*` can run in the middle of the `test-lz4-dict`
job, which will then fail, finding its files to have been axed. This adds a
dependency between the two.
according to GNU Makefile conventions,
the Makefile should feature a make check target
to self-test the generated program:
https://www.gnu.org/prep/standards/html_node/Standard-Targets.html .
this is much less thorough and less taxing than `make test`,
and can be run on any target in a reasonable timeframe (several seconds).
object files created from /tests are compiled with specific flags (`-g -DLZ4_DEBUG=1`)
which are not welcomed in release binary.
`lib/*.o` files created from /tests are now stored in /tests, to avoid unintentional mix.
When no output filename is specified and stdout is not a terminal,
lz4 doesn't attempt to guess an output filename and uses stdout for
output.
This change fixes test-lz4-basic when run without a terminal
by specifying output filenames.
