2 23:30:44 +0800'>2018-04-02builtin: Move echo space/nl handling into print_escape_strHerbert Xu Currently echocmd uses print_escape_str to do everything apart from printing the spaces/newlines separating its arguments. This patch moves the actual printing into print_escape_str as well using the format parameter. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> 2018-04-02builtin: Fix echo performance regressionHerbert Xu The commit d6c0e1e2ffbf7913ab69d51cc794d48d41c8fcb1 ("[BUILTIN] Handle embedded NULs correctly in printf") caused a performance regression in the echo built-in because every echo call now goes through the printf %b slow path where the string is always printed twice to ensure the space padding is correct in the presence of NUL characters. In fact this regression applies to printf %b as well. This is easily fixed by making printf %b take the fast path when no precision/field width modifiers are present. This patch also changes the second strchurnul call to strspn which generates slightly better code.

You're right. The proper fix to this is to ensure that nulonly is not set in varvalue for $*. It should only be set for $@ when it's inside double quotes. In fact there is another bug while we're playing with $@/$*. When IFS is set to a non-whitespace character such as :, $* outside quotes won't remove empty fields as it should. This patch fixes both problems.

First of all our tracking of quotemark is wrong so anything after "$@" becomes quoted. Once we fix that then the problem is that the first space character after "$@" is not recognised as an IFS. This patch fixes both.
