Réorganiser la liste des extensions PHP


Il m’est arrivé que php segfault (plante) sans raison apparente et sans logger aucune information, le script ci-dessous réorganise l’ordre dans lequel les modules sont chargé.


# =============================================================
# Fix php/extensions.ini order
# Script based on the idea and information(s) of
# - http://www.pingle.org/2007/09/22/php-crashes-extensions-workaround
# - http://nerdstock.org/php_extensions
# Please copy your original php/extensions.ini to a save place before
# running this script!
# There is no guaranty the script is working for you or don't damage
# your system. Use at own Risk!

if [ ! -e ${INI} ] ; then
    echo "cannot find ${INI}"
    exit 1

# cleanup previous run
[ -e ${INI}.new ] && rm -f ${INI}.new
cp -f ${INI} ${INI}.work

for e in ${EXT}; do
    if egrep -q "^extension=${e}" ${INI}.work ; then
        echo extension=${e} >> ${INI}.new
        sed -i '' -e "/${e}/d" ${INI}.work

if [ -s ${INI}.work ]; then
    echo "; additional extension(s) not known by $(basename $0)" >> ${INI}.new
    # sybase_ct needs to be loaded last.
    grep ^extension ${INI}.work | grep -v sybase_ct.so >> ${INI}.new
    grep ^extension=sybase_ct.so ${INI}.work >> ${INI}.new
[ -e ${INI}.work ] && rm -f ${INI}.work
if cmp -s ${INI} ${INI}.new ; then
    echo "No changes found, remove ${INI}.new"
    rm -f ${INI}.new

if [ ${AE} -ne 0 ]; then
cat << _EOF
New INI is saved as ${INI}.new

Additional extension(s) not known by $(basename $0)
are added to the end of new INI file.

Please review the new INI, and replace it on your own!
    Do some Basic tests:
    php -V
    php -m
    php -i
    apachectl graceful


cat << _EOF
If the segfault issue is not gone, or you cannot find the issue
    - ask on the [email protected] mailing list
    - open a PR:
    Synopsys: lang/php5 Segmentation fault.
    Additional try debugging with command:
    gdb php ./php.core
