This is similar to what was previously done for 'su': commit e5244175b (su: use correct option when cmd.exe is used as shell). Adds 48-64 bytes. (GitHub issue #438) 2024-08-05T10:08:10+00:00 Ron Yorston rmy@pobox.com 2024-08-05T10:08:10+00:00 urn:sha1:2a09008c8eab35b5cc0422fab333ca657877256c Add the '-s' option to allow an alternative shell to be given. No PATH search is performed for the shell, so an absolute or relative path to a suitable executable must be provided. Adds 80-96 bytes. (GitHub issue #438) 2023-09-14T07:09:14+00:00 Ron Yorston rmy@pobox.com 2023-09-14T07:09:14+00:00 urn:sha1:0475b7a649209487269e35cbe49662a33524e6ae Add two utility functions to convert Windows process exit codes. - exit_code_to_wait_status() converts to a POSIX wait status. This is used in ash and the implementations of system(3) and mingw_wait3(). - exit_code_to_posix() converts to a POSIX exit code. (Not that POSIX has much to say about them.) As a result it's possible for more applets to report when child processes are killed as if by a signal. 'time', 'drop' and 'su -W', for example. Adds 64-80 bytes. 2023-06-05T10:30:39+00:00 Ron Yorston rmy@pobox.com 2023-06-05T10:30:39+00:00 urn:sha1:6fcf8ade94f6cb05a57562abb6a5491a39146682 Commit 255ebaf535 (drop: adjust environment on privilege change) added USERNAME to the variables subject to special treatment when the shell starts or privilege is dropped. It's been pointed out this may not be appropriate for a variable that's Windows-specific. Remove the special treatment of USERNAME. Saves 40-48 bytes. (GitHub issue #300) 2023-05-23T09:57:56+00:00 Ron Yorston rmy@pobox.com 2023-05-23T09:57:56+00:00 urn:sha1:c2eb45989fcd59617884dc853743b5cc94b15935 Use the new kill_child_ctrl_handler() function: - Ctrl-C can be used to terminate non-console applications. - Ctrl-C in an interactive cmd.exe or PowerShell session won't cause drop to terminate. Also: - Use getopt32() to process options. - Update usage messages. Adds 96-160 bytes. 2023-04-23T08:04:01+00:00 Ron Yorston rmy@pobox.com 2023-04-23T08:00:04+00:00 urn:sha1:0575aaaa0779812752427badbc0f80a09aac02a4 Export the function xappendword() from make. Use it in drop and watch. Saves 8-80 bytes, an unusually large disparity. 2023-03-27T07:57:40+00:00 Ron Yorston rmy@pobox.com 2023-03-27T07:57:40+00:00 urn:sha1:255ebaf535c9f6d8a88e23d55d8be04b0ea73343 Some environment variables are subject to special treatment: USER, LOGNAME, HOME and SHELL are initialised when the shell starts if they don't already have a value. Some adjustments are necessary when changing privilege level: - USERNAME is added to the set of variables subject to special treatment. Unlike the others this is normally set on Windows. - The special variables are now also updated on shell start up if the current process is running with elevated privileges. This is necessary so USER, USERNAME and LOGNAME have the correct value. - USER, USERNAME and LOGNAME are set to the name of the unprivileged user when elevated privileges are dropped, though not if they've been changed from the expected value of "root". Costs 160-208 bytes. (GitHub issue #300) 2023-03-23T11:29:34+00:00 Ron Yorston rmy@pobox.com 2023-03-23T11:29:34+00:00 urn:sha1:f491e57d1ce04ec8124b9605268e5ecd3b1fb489 The cdrop and pdrop variants don't require the binary to include a shell. Removing this dependency makes it possible to build cdrop/pdrop as a much smaller standalone binaries. Update the default configuration to build a standalone make binary to exclude drop/cdrop/pdrop. 2023-03-23T08:00:36+00:00 Ron Yorston rmy@pobox.com 2023-03-23T08:00:36+00:00 urn:sha1:138e956a2e34d1b708366b6286687766a7176341 Rather than hardcode the paths of cmd.exe and PowerShell find them by searching PATH. Saves 104-128 bytes. (GitHub issue #240) 2023-03-19T10:26:24+00:00 Ron Yorston rmy@pobox.com 2023-03-19T10:26:24+00:00 urn:sha1:d9e8bb61cf380264511a4524281af2ca57498bce Add cdrop and pdrop applets as aliases for drop. If a command isn't specified these use cmd.exe and PowerShell instead of the BusyBox shell. This makes it possible to choose the default shell used for SSH connections even in older versions of OpenSSH that don't support the DefaultShellArguments registry key. Note that to get cmd.exe to run a command rather than an interactive shell it's necessary to set the DefaultShellCommandOption registry key to '/c'. Costs 248-272 bytes.
