ash: Expand here-documents in the current shell environment

2020-02-22T19:29:36+00:00

Upstream commit: Date: Sun, 11 Nov 2007 15:27:00 +0800 Expand here-documents in the current shell environment Previously we always expanded here-documents in a subshell. This is contrary to the POSIX specification and how other shells behave. What's more this slows down many expansions due to the extra fork (however, it must be said that it is possible for it speed up certain expansions by running it simultaneously with the command on two CPUs). This patch move the expansion into the current shell environment. Test case: unset a cat <<- EOF > /dev/null ${a=NOT} EOF echo ${a}BAD Old result: BAD New result: NOTBAD Signed-off-by: Denys Vlasenko

hush: fix nested redirects colliding with script fds

2018-07-24T14:54:41+00:00

This necessitates switch from libc FILE api to a simple homegrown replacement. The change which fixes the bug here is the deleting of restore_redirected_FILEs(); line. It was prematurely moving (restoring) script fd#3. The fix is: we don't even _want_ to restore scrit fds, we are perfectly fine with them being moved. The only reason we tried to restore them is that FILE api did not allow moving of FILE->fd. function old new delta refill_HFILE_and_getc - 93 +93 hfopen - 90 +90 hfclose - 66 +66 pseudo_exec_argv 591 597 +6 hush_main 1089 1095 +6 builtin_source 209 214 +5 save_fd_on_redirect 197 200 +3 setup_redirects 320 321 +1 fgetc_interactive 235 236 +1 i_peek_and_eat_bkslash_nl 99 97 -2 expand_vars_to_list 1103 1100 -3 restore_redirects 99 52 -47 fclose_and_forget 57 - -57 remember_FILE 63 - -63 ------------------------------------------------------------------------------ (add/remove: 3/2 grow/shrink: 6/3 up/down: 271/-172) Total: 99 bytes Signed-off-by: Denys Vlasenko
