#
# This program is meant for authors or maintainers which want to import
# modules from gnulib into their packages.
# CODING STYLE for this file:
# * Indentation: Indent by 2 spaces. Indent case clauses by 2 spaces as well.
# * Shell variable references: Use double-quote around shell variable
# references always (except when word splitting is explicitly desired),
# even when you know the double-quote are not needed. This style tends to
# avoid undesired word splitting caused by omitted double-quotes (the
# number one mistake in shell scripts).
# When the referenced variable can only have a finite number of possible
# values and these values are all simple words (e.g. true and false), it's
# OK to omit the double-quotes.
# * Backquotes:
# - Use backquotes like in `command`, not $(command).
# - Don't use `command` inside double-quotes. Instead assign the result of
# `command` to a variable, and use the value of the variable afterwards.
# * Functions:
# - All functions that don't emulate a program or shell built-in have a name
# that starts with 'func_'.
# - Document the implicit and explicit arguments of all functions, as well
# as their output variables and side effects.
# * Use test condition instead of [ condition ].
# * Minimize the use of eval; when you need it, make sure the string to be
# evaluated has a very simple syntactic structure.

# Ensure an 'echo' command that
# 1. does not interpret backslashes and
# 2. does not print an error message "broken pipe" when writing into a pipe
# with no writers.
#
# Test cases for problem 1:
# echo '\n' | wc -l prints 1 when OK, 2 when KO
# echo '\t' | grep t > /dev/null has return code 0 when OK, 1 when KO
# Test cases for problem 2:
# echo hi | true frequently prints
# "bash: echo: write error: Broken pipe"
# to standard error in bash 3.2.
#
# Problem 1 is a weird heritage from SVR4. BSD got it right (except that
# BSD echo interprets '-n' as an option, which is also not desirable).
# Nowadays the problem occurs in 4 situations:
# - in bash, when the shell option xpg_echo is set (bash >= 2.04)
# or when it was built with --enable-usg-echo-default (bash >= 2.0)
# or when it was built with DEFAULT_ECHO_TO_USG (bash < 2.0),
# - in zsh, when sh-emulation is not set,
# - in ksh (e.g. AIX /bin/sh and Solaris /usr/xpg4/bin/sh are ksh instances,
# and HP-UX /bin/sh behaves similarly),
# - in Solaris /bin/sh.
# We try the following workarounds:
# - for all: respawn using $CONFIG_SHELL if that is set and works.
# - for bash >= 2.04: unset the shell option xpg_echo.
# - for bash >= 2.0: define echo to a function that uses the printf built-in.
# - for bash < 2.0: define echo to a function that uses cat of a here document.
# - for zsh: turn sh-emulation on.
# - for ksh: alias echo to 'print -r'.
# - for ksh: alias echo to a function that uses cat of a here document.
# - for Solaris /bin/sh: respawn using /bin/ksh and rely on the ksh workaround.
# - otherwise: respawn using /bin/sh and rely on the workarounds.
# When respawning, we pass --no-reexec as first argument, so as to avoid
# turning this script into a fork bomb in unlucky situations.
#
# Problem 2 is specific to bash 3.2 and affects the 'echo' built-in, but not
# the 'printf' built-in. See
# <https://lists.gnu.org/r/bug-bash/2008-12/msg00050.html>

# 1) Because parts of the Gnulib tests exercise corner cases (invalid
# arguments, endless recursions, etc.) that a compiler may warn about,
# even with just the normal '-Wall' option.
# 2) Because every package maintainer has their preferred set of warnings
# that they may want to enforce in the main source code of their package,
# and some of these warnings (such as '-Wswitch-enum') complain about code
# that is just perfect.
# But Gnulib tests are maintained in Gnulib and don't end up in binaries
# that that package installs; therefore it does not make sense for
# package maintainers to enforce the absence of warnings on these tests.
# Why before @CFLAGS@?
# - Because "the user is always right": If a user adds '-Werror' to their
# CFLAGS, they have asked for errors, they will get errors. But they have
# no right to complain about these errors, because Gnulib does not support
# '-Werror'.
