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

parser: Fix backquote support in here-document EOF mark

2018-04-01T14:38:32+00:00

Upstream commit: Author: Herbert Xu Date: Thu Mar 15 18:27:30 2018 +0800 parser: Fix backquote support in here-document EOF mark Currently using backquotes in a here-document EOF mark is broken because dash tries to do command substitution on it. This patch fixes it by checking whether we're looking for an EOF mark during tokenisation. Reported-by: Harald van Dijk Signed-off-by: Herbert Xu With added fix for quoted-ness of the EOF mark.

ash: use pgetc_eatbnl() in more places

2018-03-31T17:40:56+00:00

Part of upstream commit: Date: Thu Mar 8 08:37:11 2018 +0100 Author: Harald van Dijk parser: use pgetc_eatbnl() in more places dash has a pgetc_eatbnl function in parser.c which skips any backslash-newline combinations. It's not used everywhere it could be. There is also some duplicated backslash-newline handling elsewhere in parser.c. Replace most of the calls to pgetc() with calls to pgetc_eatbnl() and remove the duplicated backslash-newline handling. Signed-off-by: Herbert Xu Not adding "readtoken1(pgetc_eatbnl(), DQSYNTAX..." changes, since readtoken1() handles the "starts with backslash + newline" case itself. Signed-off-by: Denys Vlasenko
