A recent commit made it possible to execute such binaries reliably, but that does require them to be installed. As an alternative solution: if a binary with a standard Unix path prefix can't be found but is available as a built-in applet, run the applet. Add the function unix_path() to detect paths starting with /bin, /usr/bin, /sbin or /usr/sbin. Use this function in: - the 'which' applet - shellexec(), describe_command() and find_command() in ash - mingw_spawn_1() See GitHub issue #195. 2020-08-13T13:58:01+00:00 Ron Yorston rmy@pobox.com 2020-08-13T12:56:17+00:00 urn:sha1:6059723900f2af1fbd394c457d1feae342e344f6 As noted in commit 548ec7045 (win32: interpret absolute paths as relative to %SYSTEMDRIVE%) a path starting with a '/' in the Unix world is treated as relative to the current drive by Windows. To avoid ambiguity that commit considered certain such paths to be relative to %SYSTEMDRIVE%. Extend this to paths representing executables. Add the functions need_system_drive() and auto_add_system_drive() to detect the need for a system drive prefix and to add it if necessary. Use these functions in: - the 'which' applet - the find_executable() function - tab-completion code - PATH look-up, shellexec(), describe_command() and find_command() in ash - parse_interpreter() and mingw_spawn_1() With these changes executable paths starting with a slash are handled consistently, whatever the current drive. 2020-08-13T13:58:01+00:00 Ron Yorston rmy@pobox.com 2020-08-13T10:43:26+00:00 urn:sha1:7d639339e0c46311f8873d560e6f168e71473cd9 Allocate static storage for the system drive string instead of making a new allocation on every call. This is easier to manage. Adds 16 bytes. 2020-08-13T13:58:01+00:00 Ron Yorston rmy@pobox.com 2020-08-13T10:36:29+00:00 urn:sha1:258ad6a1d52f1811f9de1d6b976f3797f5b31a2b Add a new function, has_path(), to detect that an executable name doesn't require a path look-up. Also, since is_absolute_path() is now only used in shell/ash.c move its definition there from include/mingw.h. Saves 128 bytes. 2020-08-05T14:33:12+00:00 Ron Yorston rmy@pobox.com 2020-08-05T14:33:12+00:00 urn:sha1:4319228f3dcf3a5f941140482c30cca227c6ed0b Use a new common function, mingw_fork_compressor(), to implement fork_transformer() in open_transformer.c and vfork_compressor() in tar.c. Saves 160 bytes. 2020-08-03T15:09:38+00:00 Ron Yorston rmy@pobox.com 2020-08-03T15:09:38+00:00 urn:sha1:597dc43c9c8dad0daf9d4d0648e3e83c352b4ffd Update to latest code from gnulib. This adds a '%q' (quarter) field descriptor. Remove the 'neg' variable from the code to handle the '%z' (timezone) field descriptor. Since our struct tm lacks a tm_gmtoff member '%z' is only supported "for reasons of symmetry". Since the computed value is never used there's no need to negate it. 2020-07-25T11:48:13+00:00 Ron Yorston rmy@pobox.com 2020-07-25T11:48:13+00:00 urn:sha1:cfa888eb571d92d4de02b406f0dad15e4fa26d19 - 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. 2020-07-21T07:15:51+00:00 Ron Yorston rmy@pobox.com 2020-07-21T07:15:51+00:00 urn:sha1:2974f8f44cdb029f040cc2a975592daf965817af 2020-07-09T13:01:01+00:00 Ron Yorston rmy@pobox.com 2020-07-09T13:01:01+00:00 urn:sha1:251c93fdeca77a7bed0075bcd74d55ad741f7bbb 2020-07-09T07:48:52+00:00 Ron Yorston rmy@pobox.com 2020-07-09T07:48:52+00:00 urn:sha1:ea3041f90d719e1f14c6149759a56af78dbae101 Until now the emulated stat(2) system calls have only returned a synthesised Unix-style mode value. Also return the raw Windows file attributes.
