New features with AN-2016-04-28: This is the first localization step for the schily source consolidation. Many programs now (hopefully) call gettext() for all strings that need localization. - The next step will include dgettext() calls for the libraries and the missing programs - The following step will include the extracted strings - The last step will include German translations and install support for the resulting binary message object files. ----------> Please test and report compilation problems! <--------- ***** NOTE: As mentioned since 2004, frontends to the tools should ***** ***** call all programs in the "C" locale ***** ***** by e.g. calling: LC_ALL=C cdrecord .... ***** ***** unless these frontends support localized strings ***** ***** used by the cdrtools with NLS support. ***** *** WARNING *** *** Need new smake *** *** Due to the fact that schily-tools 2014-04-03 introduced to use new macro *** expansions and a related bug fix in smake, you need a new smake *** to compile this source. To ensure this, call: cd ./psmake ./MAKE-all cd .. psmake/smake psmake/smake install WARNING: the new version of the isoinfo program makes use of the *at() series of functions that have been introduced by Sun in August 2001 and added to POSIX.1-2008. For older platforms, libschily now includes emulations for these functions but these emulations have not yet been tested thoroughly. Please report problems! The new smake version mentioned above is smake-1.2.4 - Libgetopt: Some Cstyle changes and a better comment. - Libgetopt: man page getopt.3c added. Note, that it is not installed automatically as it may be in conflict with the systems getopt() man page. - Bourne Shell: Does no longer write warnings "cannot export functions" as we permit functions and variables with the same name. Even when a name currently refers to a function, it may now later become a variable too. Thanks to Robert Elz for reporting. - Bourne Shell: A 32 bit Bourne Shell no longer gets an integer overflow while computing the CPU time percentage. This happened e.g. while compiling OpenSolaris-ON that takes more than 2 hours on a 2-CPU intel machine from today and reported 27% CPU usage while it should have reported aprox. 180% CPU usage. - Bourne Shell: I/O redirect errors (e.g. from non existing input files or when set -C prevents to clobber files) do no longer cause a shell script to exit or an interactive shell to longjmp before the next prompt when this happens with a builtin command or function. This is required for POSIX. Thanks to Robert Elz for reporting. - Bourne Shell: String manipulation: ${parameter%word} ${parameter%%word} ${parameter#word} ${parameter##word} now works correctly even when the above conversions appear in double quotes. Thanks to Robert Elz for reporting. - Bourne Shell: added 12 new tests in the "parameter" section of the conformance tests to check whether the above bug reported by Robert Elz has been fixed. - Bourne Shell: set -e again makes sure that the shell exits even with those errors that have recently been made non-fatal by calling: command - Bourne Shell: New test for the testsuite now checks whether sh -ce 'cmd' is handled correctly for complex commands. This is the test that is used to detect a failure with bash-3.x in our autoconf. - Bourne Shell Missing features for POSIX compliance: - Arithmetic Substitution with $((expression)) - Do not list functions when calling "set" with no arguments. Note that this POSIX requirement is seen as a POSIX bug as there is no POSIX command to list function definitions. NOTE that this will not be implemented before POSIX bug http://austingroupbugs.net/view.php?id=1025 was fixed. - A POSIX whitepaper at: http://www.unix.org/whitepapers/shdiffs.html claims that: IFS=o; violet should not execute "vi". The normative text in the POSIX standard describes the historic Bourne Shell behavior, but the rationale describes the deviating behavior from "ksh". - Support for $'...' quoting (this is not needed for the current version of POSIX but for the next POSIX version that will be SUSv8) We are getting very close to full POSIX support. - Bourne Shell further TODO list: - Try to make lastline= while read line do lastline=$line done < /etc/passwd echo "lastline=$lastline" print the last line of /etc/passwd without the exec "trick" that is documented in the man page. - Finish loadable builtin support. - POSIX does not allow us to implement ". -h", so we will add a "source" builtin to be able to implement "source -h" - The following builtins (that are available in bsh) are still missing in the Bourne Shell: err echo with output going to stderr glob echo with '\0' instead of ' ' between args env a builtin version of /usr/bin/env The following bsh intrinsics are still missing in the Bourne Shell: - the restricted bsh has restriction features that are missing in the Bourne shell. - source -h read file into history but do not excute and probably more features not yet identified to be bsh unique.
