b0b3&follow=1'>redir: Fix typo in noclobber codeHerbert Xu The noclobber code has a typo in it that causes it to fail. This patch fixes it. Reported-by: Denys Vlasenko <vda.linux@googlemail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> 2018-04-19expand: Fix glibc glob(3) supportHerbert Xu It's been a while since we disabled glob(3) support by default. It appears to be working now, however, we have to change our code to detect the no-match case correctly. In particular, we need to test for GLOB_NOMAGIC | GLOB_NOCHECK instead of GLOB_MAGCHAR. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> 2018-04-02expand: Fix buffer overflow in expandmetaHerbert Xu The native version of expandmeta allocates a buffer that may be overrun for two reasons. First of all the size is 1 byte too small but this is normally hidden because the minimum size is rounded up to 2048 bytes. Secondly, if the directory level is deep enough, any buffer can be overrun. This patch fixes both problems by calling realloc when necessary. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> 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.
