Denys Vlasenko 41ef41b3e0 hush: fix nested redirects colliding with script fds ... 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 <vda.linux@googlemail.com>		2018-07-24 16:54:41 +02:00
