ash: move parse-time quote flag detection to run-time

2015-05-18T07:57:51+00:00

Because the parser does not recursively parse parameter expansion with respect to quotes, we can't accurately determine quote status at parse time. This patch works around this by moving the quote detection to run-time where we do interpret it recursively. Test case: foo=\\ echo "<${foo#[\\]}>" Old result: <\> New result: <> Do not quote back slashes in parameter expansions outside quotes. Test case: a=/b/c/* b=\\ echo ${a%$b*} Old result: /b/c/* New result: /b/c/ Based on commits 880d952, 7cfd8be, 0d7d660 and a7c21a6 from git://git.kernel.org/pub/scm/utils/dash/dash.git by Herbert Xu function old new delta argstr 1164 1193 +29 memtodest 147 174 +27 subevalvar 1153 1177 +24 redirect 1279 1282 +3 dolatstr 5 7 +2 static.spclchars 10 9 -1 expandarg 962 960 -2 evalcase 273 271 -2 evalcommand 1204 1197 -7 rmescapes 236 227 -9 preglob 27 8 -19 evalvar 604 582 -22 cmdputs 389 334 -55 readtoken1 3163 3061 -102 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 5/9 up/down: 85/-219) Total: -134 bytes Signed-off-by: Ron Yorston Signed-off-by: Denys Vlasenko

ash: remove arithmetic expansion collapsing at parse time

2015-05-18T07:56:16+00:00

Collapsing arithmetic expansion is incorrect when the inner arithmetic expansion is a part of a parameter expansion. Test case: unset a echo $((3 + ${a:=$((4 + 5))})) echo $a Old result: 12 (4 + 5) New result: 12 9 Based on commit bb777a6 from git://git.kernel.org/pub/scm/utils/dash/dash.git by Herbert Xu function old new delta readtoken1 3180 3163 -17 Signed-off-by: Ron Yorston Signed-off-by: Denys Vlasenko
