* [BUILD] Fixed build on NetBSDAleksey Cheusov2009-01-13
| | | | | | | | | | Hi, I propose to apply the following patch for dash. The problem is alloca.h is absent on many platforms including NetBSD I'm running. Also, NetBSD's version of mktemp doesn't work without temporary filename pattern. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [MAN] Removed obsolete for loop syntaxHerbert Xu2008-10-17
| | | | | | | | Sven Mascheck reported that we no longer accept the non-standard for {} syntax but the manual page still refers to it. This patch removes that reference. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* [MAN] Added missing right parenthesisGerrit Pape2008-07-13
| | | | | | | | | | | | | | In section Redirection the following text misses a left brace: where redir-op is one of the redirection operators mentioned previously. Following is a list of the possible redirections. The [n] is an optional number, as in \u20183\u2019 (not \u2018[3]\u2019, that refers to a file descriptor.

* [BUILTIN] Made t_lex reentrantHerbert Xu2008-07-13
| | | | | | | The previous two changes were broken because t_lex uses global state. This patch removes that by making t_wp local to t_lex. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [BUILTIN] Made aexpr/oexpr non-recursiveHerbert Xu2008-07-13

* [EXPAND] Fixed non-leading slash treatment in expmetaHerbert Xu2008-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | Back in January an attempt was made to fix the interpretation of quoted slashes in expmeta. However, this only fixed those cases where the quoted slash is at the front of the word. The case of non-leading slashes caused the previous directory part to gain a back slash suffix which causes subsequent pattern matches to fail. This patch fixes this by removing the back slash in that case. Thanks to Romain Tartière fox reporting this bug. Test case: echo /*"/null" Old result: /*/null New result: /dev/null Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* [SHELL] Use uninitialized_var to silence bogus warningsHerbert Xu2008-05-03
| | | | | | | | gcc generates bogus warnings about uninitialised variables in parser.c. This patch borrows the uninitialized_var macro from Linux to silence them. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [SHELL] Fixed klibc/klcc build problemsDan McGee2008-05-03
| | | | | | | | | | | | klibc does not have mempcpy, so system.h must be included where this is used to provide the replacement. glob.h doesn't exist, so we need to guard this include with the HAVE_GLOB definition. Finally, klcc didn't like the syntax of the main definition in mksignames, and the resulting program segfaulted when trying to dereference any part of the argv array. Updating the main function definition solved the problem. Signed-off-by: Dan McGee <dpmcgee@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* [JOBS] Fix cmdtxt crash on if statementsLarry Doolittle2008-05-02
| | | | | | | | | | | | | | | | (Herbert: for context, see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=467065 ) This is a real bug in upstream dash, which has existed since at least dash-0.5.1 (July 2004). It is a latent bug in cmdtxt() (which I think applies only to pipes) as it handles "if" commands. The attached patch fixes it for me. It's possible this patch will fix one or more of #462414, #462977, and #463649. I'll send messages there to see if the submitters can test. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [EXPAND] Fix slash treatment in expmetaHerbert Xu2008-05-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The change [EXPAND] Do not quote back slashes in parameter expansions outside quotes triggered a latent bug in expmeta where the forward slashes when preceded by a blackslash weren't recognised as directory separators. This was hidden because a work-around was put in place for glob(3) which meant that we never had any backslashes immediately before forward slashes. This patch fixes the metaflag loop to recognise forward slashes even when they follow a backslash. Thanks to Daniel Hahler for reporting this problem.

* [PARSER] Do not show prompts in expandstrHerbert Xu2007-12-27
| | | | | | | | | | Once I fixed the previous problem it became apparent that we never dealt with prompts with new-lines in them correctly. The problem is that we showed a secondary prompt for each of them. This patch disables prompt generation in expandstr. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [PARSER] Add FAKEEOFMARK for expandstrHerbert Xu2007-12-27
| | | | | | | | | | | | | | | | Previously expandstr used the string "" to indicate that it needs to be treated just like a here-doc except that there is no terminator. However, the string "" is in fact a valid here-doc terminator so now that we deal with it correctly expandstr no longer works in the presence of new-lines in the prompt. This patch introduces the FAKEEOFMARK macro which does not equal any real EOF marker but is distinct from the NULL pointer which is used to indicate non-here-doc contexts. Thanks to Markus Triska for reporting this regression. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* [BUILTIN] Add set +o supportRichard M Kreuter2007-12-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dash(1) in Debian stable does not support "set +o" in the manner specified by SUSv3: |+o | Write the current option settings to standard output in a format | that is suitable for reinput to the shell as commands that | achieve the same options settings. (citation from http://www.opengroup.org/onlinepubs/009695399/utilities/set.html) Instead, dash's "set +o" prints the shell's options in a human-readable format. Here is a simple test program that exercises this feature; it works as I believe is required under bash, but not under dash. # Save the shell's options set +o > /tmp/settings-commands set -o | sort > /tmp/settings-before # Change some options. set -v set -f set -x set +o emacs set -o vi # Try to restore our options. . /tmp/settings-commands set -o | sort > /tmp/settings-after # Compare. diff /tmp/settings-before /tmp/settings-after I believe the following small patch adds this feature to dash, and documents it in the manual page: Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* [EXPAND] Expand here-documents in the current shell environmentHerbert Xu2007-11-11
| | | | | | | | | | | | | | | | | | | | | | | | | | Previously we always expanded here-documents in a subshell. This is contrary to the POSIX specification and how other shells behave. What's more this slows down many expansions due to the extra fork (however, it must be said that it is possible for it speed up certain expansions by running it simultaneously with the command on two CPUs). This patch move the expansion into the current shell environment. Test case: unset a cat <<- EOF > /dev/null ${a=NOT} EOF echo ${a}BAD Old result: BAD New result: NOTBAD
* [EXPAND] Removed herefd hackHerbert Xu2007-11-11
| | | | | | | | | | | The herefd hack goes back more than a decade. it limits the amount of memory we have to allocate when expanding here-documents by writing the result out from time to time. However, it's no longer safe because the stack is used to place intermediate results too and there we certainly don't want to write them out should we be short on memory. In any case, with today's computers we can afford to keep the entire result in memory and write them out at the end.

* [EXPAND] Added configure --enable-glob and --enable-fnmatch optionsHerbert Xu2007-10-20
| | | | | | | | Debian's libc6 as of 2.6.1-6 has working glob(3)/fnmatch(3) support. This patch adds the options --enable-glob and --enable-fnmatch to the configure script. By default glob(3) and fnmatch(3) are still unused. However, on distros where the glibc is known to work you may enable these options.
* [SHELL] Replace shared illnum message by badnum function.Herbert Xu2007-10-17
| | | | | | This patch adds the badnum function and uses it to mostly replace the use of illnum except in miscbltin where the current code turns out to be smaller because of the twin sh_error calls.

* [BUILTIN] Treat OPTIND=0 in the same way as OPTIND=1Herbert Xu2007-10-06
| | | | | | | | Previously setting OPTIND to 0 would cause subsequent getopts calls to fail. This patch makes dash reset the getopts parameters the same way as OPTIND=1. Both behaviours are allowed by POSIX but other common shells do tolerate this case.
* [MEMALLOC] Add pushstackmarkHerbert Xu2007-10-06
| | | | | | | | This patch gets rid of the stack mark tracking hack by allocating a little bit of stack memory if we're at risk of planting a stack mark which may be grown later. To do this a new function pushstackmark is added which lets the user pick a bigger amount to allocate since some users do that anyway after setting a stack mark.

| | | | | | | | | | | | | | | | | | | | | | | | Previously dash required a <newline> character to be present in order for a here-document delimiter to be detected. Allowing EOF in the absence of a <newline> to play the same purpose allows some intuitive scripts to succeed. POSIX seems to be silence on this so this should be OK. Test case: eval 'cat <<- NOT test NOT' echo OK Old result: test NOTOK New result: test OK
