* Make dynamic link of libiconv from ports work again.Hajimu UMEMOTO2016-02-021-3/+3
| | | | | | | | | | | | | | The symbols of libiconv from ports were changed to have prefixed. Since we have iconv in our libc these days, we don't need it on 10.X and later. However, 9.X still need this. Spotted by: Yoshihiko Sarumaru MFC after: 1 days Notes: svn path=/head/; revision=295147
* sh: Don't allocate a redirtab if there are no redirections.Jilles Tjoelker2016-01-301-7/+22
| | | | | | | | | | | | | | | | | | | | Builtins (including variable assignments without command word), function calls and redirected compound commands need to restore file descriptors to their original state after execution. This is handled by allocating a redirtab structure. These mallocs and frees show up heavily in pmcstat. Only allocate a redirtab if there are actually redirections and maintain a count of how many levels of REDIR_PUSH there are without redirtabs. A simple loop without external programs like sh -c 'i=0; w=$(printf %0100d 7); while [ "$i" -lt 1000000 ]; do i=$((i+1)); done' is over 25% faster on an amd64 bhyve VM. Notes: svn path=/head/; revision=295085
* sh(1): Document 'cd -'.Jilles Tjoelker2016-01-301-6/+19
| | | | | | | | This reflects the changes in r294649 and can therefore not be MFCed by itself. Notes: svn path=/head/; revision=295083
* test: Optimize operator lookup.Jilles Tjoelker2016-01-301-67/+97
| | | | | | | | | | | | | | | | | The linear search using strcmp() shows up in pmcstat for several percent. Split the operators into lengths and whether they start with '-' and compare bytes using == instead of strcmp(). A simple test sh -c 'i=0; w=$(printf %0100d 7); while [ "$i" -lt 1000000 ]; do v=$(printf %sx%s "$w" "$w"); i=$((i+1)); done' is over 4% faster on an amd64 bhyve VM.

* sh: Constify internal representation in expand.c.Jilles Tjoelker2016-01-241-22/+28
| | | | | | | | | | Forbid (temporary or permanent) modifications of the strings in NARG nodes during expansion. Tilde expansion now needs to copy the username for the terminating '\0'. Notes: svn path=/head/; revision=294692

* sh: Use OLDPWD shell variable for 'cd -'.Jilles Tjoelker2016-01-231-10/+9
| | | | | | | | | | | Per POSIX, 'cd -' should use the OLDPWD shell variable, not internal state. This variable is normally exported. Also, if OLDPWD is not set, fail 'cd -' instead of changing to the current directory. Notes: svn path=/head/; revision=294649

* sh: Clean a readonly local, even if the variable does not exist outside.Jilles Tjoelker2016-01-223-0/+12
| | | | | | | | If a local variable has been made read-only, this should not prevent its removal when the function returns. Notes: svn path=/head/; revision=294593

* sh: Update associated state when restoring locals while leaving a function.Jilles Tjoelker2016-01-104-2/+29
| | | | | | | | | | | Some variables like PATH call a function when modified. Make sure to call this also when leaving a function where such a variable was made local. Make sure to restore local variables before shellparam, so getopts state is not clobbered. Notes: svn path=/head/; revision=293635
* sh: Reduce size of options table.Jilles Tjoelker2016-01-074-71/+71
| | | | Notes: svn path=/head/; revision=293392
* sh: Add a test for 'cd -'.Jilles Tjoelker2016-01-073-0/+11
| | | | | | | | | Redirect 'cd -' output to /dev/null since POSIX requires it to write the new directory name even if not interactive, but we currently only write it if interactive. Notes: svn path=/head/; revision=293371
* sh: Ensure OPTIND=1 in subshell without forking does not affect outer env.Jilles Tjoelker2016-01-073-0/+19
| | | | | | | | | | | | | | | Command substitutions containing a single simple command and here-document expansion are performed in a subshell environment, but may not fork. Any modified state of the shell environment should be restored afterward. The state that OPTIND=1 had been done was not saved and restored here. Note that the other parts of shellparam need not be saved and restored, since they are not modified in these situations (a fork is done before such modifications).

* sh: Remove redundant CTLQUOTEMARK checks.Jilles Tjoelker2015-12-311-18/+2
| | | | | | | | | | | With the new expand.c code, the intermediate representation passed to the pathname generation code only contains CTLESC, not CTLQUOTEMARK. CTLQUOTEMARK now only occurs in the text of NARG nodes (output of the parser). Notes: svn path=/head/; revision=293002

* sh: Perform pathname generation during the first expansion phases.Jilles Tjoelker2015-12-312-52/+57
| | | | | | | | | | | This avoids the need to add and remove CTLESC bytes if pathname generation will not be performed (set -f). Side effect: the order of operations is slightly different: pathname generation in ${$+* $(CMD)} will not see filesystem changes from CMD. Notes: svn path=/head/; revision=292994
* sh: Perform IFS splitting during the first expansion phases.Jilles Tjoelker2015-12-311-362/+253
| | | | | | | | | | | | This simplifies the code and should be faster in some cases. Side effect: the order of operations is different so that the value of IFS used when IFS is modified during expansion (${IFS:=...}, ${IFS=...} or $((...IFS=...))) may be different. Note that this order is highly unportable between shells. Notes: svn path=/head/; revision=292991

| | | | | | | | | | | Unfortunately filemon/meta mode tracks all indirect dependencies here since ld(1) is reading libelf when linking in libkvm.
