New transfer modification features for sync and direct I/O, a minor display formatting fix, extensions to the test framework, and the first round of cleanups.
- feature: new "
--sync" option to flush cache to disk after every write (related to GH#6, to improve accuracy when writing to slow disks) - feature: new "
--direct-io" option to bypass cache - implements GH#29 "Option to enable O_DIRECT" - requested by Romain Kang, Jacek Wielemborek - fix: correct byte prefix size to 2 spaces in rate display, so progress display size remains constant at low transfer rates
- cleanup: rewrote
configure.inas per suggestions in newer "autoconf" manuals - cleanup: replaced
header.inwith one generated by "autoheader", moving custom logic to a separate header file "config-aux.h" - cleanup: added copyright notice to all source files as per GNU standards
- cleanup: changed "
--version" output to conform to GNU standards - cleanup: replaced backticks with
$()in all shell scripts that did not come from elsewhere, as backticks are deprecated and harder to read - cleanup: improved the output formatting of "
make test" - cleanup: extended the "
make test" mechanism to allow certain tests to be skipped on platforms that cannot support them - cleanup: skip the "pipe" test (for SIGPIPE) if GNU "
head" is not available, so that "make test" on stock OpenBSD 7.3 works - cleanup: added a lot more tests to "
make test" - cleanup: replace all calls to
sprintf()andsnprintf()with a new wrapper functionpv_snprintf()to improve security and compatibility - cleanup: replace all calls to
strcat()with a wrapperpv_strlcat()to improve security and compatibility - cleanup: replace all
write()calls to the terminal with a wrapperpv_write_retry()for consistency - cleanup: tidy up and fix compilation warning in "
--watchfd" code - cleanup: rewrote all local shell scripts to pass analysis by ShellCheck
