awk: speed improvements

2020-08-01T10:31:22+00:00

Improve performance in certain cases at the cost of an additional 144 bytes in the binary. - Reinstate (and fix) the original code to speed up assignment of a temporary string to a variable. - Replace use of xasprintf() for string concatentation with explicit string manipulation. This could be faster still if Windows had an optimised stpcpy(). The enhancement is not enabled by default. This test case: BEGIN{while(++i<30000) s=s i} is 18 times faster. The less extreme: BEGIN{while(++i<1000000) s="abc " i} is 30% faster. See GitHub issue #193.

win32: code shrink kill(2)

2020-07-25T11:48:13+00:00

- Drop exit_code argument from kill_SIGTERM_by_handle() - Pass signal number rather than exit code to other functions - Merge kill_SIGKILL() and kill_SIGTEST() Saves 112 bytes.

ts: correct output in 64-bit build

2020-07-19T09:39:43+00:00

ts failed to output the correct time when built for 64-bit Windows. In 64-bit builds time_t is a 64-bit quantity whereas the tv_sec member of struct timeval is 32-bit. https://sourceforge.net/p/mingw-w64/bugs/783/ Use a temporary time_t value in 64-bit builds.

win32: alter build flags

2020-07-09T15:03:57+00:00

Add -fno-builtin-strndup to the build flags, otherwise builds with link-time optimisation can't find strndup.

chattr, lsattr: enable in the default configuration

2020-07-09T08:07:55+00:00

The chattr and lsattr utilities allow file attributes to be changed and displayed. Modify them to support Windows file attributes using the same names as Cygwin. Only allow a limited subset of attributes to be changed: just most of those supported by SetFileAttributes(). Since it isn't possible to set all attributes the '=' operator isn't allowed.

ls: treat hidden files as if their names begin with a dot

2020-07-09T07:52:24+00:00

On Unix 'ls' treats filenames starting with a dot as hidden and only displays them if the '-a' or '-A' option is given. Extend similar treatment to files with the Windows hidden flag.
