God, it took me a whole month (more?) to read and this is only my third book of the year :( I need some more novellas to read, but the other books I have from the library currently are also thick.

ert Xu dash -c 'echo ${}' should print "Bad subtitution" but instead fails with "Syntax error: Missing '}'". This is caused by us reading an extra character beyond the right brace. This patch fixes it so that this construct only fails during expansion rather than during parsing. Fixes: 3df3edd13389 ("[PARSER] Report substition errors at...")

What happens is that quote removal only applies to the original token as seen by the shell. It is never applied to the result of parameter expansion. Now you may ask why on earth does the second line say "/dev/null" instead of "/dev/\null". Well that's because it is not the quote removal step that removed the backslash, but the pathname expansion. The fact that the /de\v does not become /dev even though it exists is just the result of the optimisation to avoid unnecessarily calling stat(2). I have checked POSIX and I don't see anything that forbids this behaviour. So going back to dash yes I think we should adopt the bash behaviour for pathname expansion and keep the existing case semantics. This patch does exactly that. Note that this patch does not work unless you have already applied https://patchwork.kernel.org/patch/10306507/ because otherwise the optimisation mentioned above does not get detected correctly and we will end up doing quote removal twice. This patch also updates expmeta to handle naked backslashes at the end of the pattern which is now possible. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> 2018-04-19shell: Add subdir-objects to AM_INIT_AUTOMAKEJason Bowen I've attached a patch which adds the subdir-objects option to AM_INIT_AUTOMAKE. For a while now when I've compiled dash I received a warning from automake that there are source files in a subdirectory but that the subdir-objects automake option was not supplied. I've just been adding it myself, but I finally got around to submitting a patch. The code still compiles for now (i'm using automake 1.15.1), but warning text is rarely nice to see and, if the warning text is to be believed, then the warning will eventually become an error.

This means that if you construct a loop consisting of solely built-in commands and functions, then zombies can hang around indefinitely. This patch fixes this by reaping when necessary after each built-in command and function.

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.
