Hello, especially those who add some kind of tweaks to poudriere :)
In my case, I try to make it a hook script first, so it is not affected by errexit of shell.
However, when modifying poudriere to incorporate the codes, some tmpfs are not mounted depending on USE_TMPFS value, so poudriere exits with an error when trying to handle them.
So I will post a revised version of the hook script that includes ideas to counteract that, including this one.
The file should be placed in a location that will be erased by poudriere-logclean. That would require another step to collect the results...
I don't know if multiple concurrent executions of it will occur, but even if it does, it has been changed to work exclusively.
And I am trying to use jq to get and add numbers.
If you see a point that you think is an interesting idea, cut it out and use it :)
Regards.
Below is the script.
#!/bin/sh
case "${0##*/}" in
pkgbuild.sh)
case "${1}" in # (
success|failed)
if ! [ ${LOCKF_HOOK_TMPFS:+1} ] ; then
shopt="${-}"
LOCKF_HOOK_TMPFS=1 lockf -k "${LOG}/.tmpfs.log" /bin/sh ${shopt:+"-${-}"} "${0}" ${1+"${@}"}
elif [ ${MY_JOBID:+1} ] ; then
# jq was installed by package textproc/jq
if JQ=$(which jq 2>&${OUTPUT_REDIRECTED_STDERR:-2}) ; then
realpath=$(realpath "${MASTERMNT}/../${MY_JOBID}/")
pour_xo_sauce_on_df=$(
mount -t tmpfs -p |
cut -f 2 -w |
grep -e "^${realpath}" |
xargs df -b --libxo json |
${JQ} -c -r '[.["storage-system-information"].filesystem[].["used-blocks"]]|add//-0'
)
tmpfs_at_end=$(
echo "${pour_xo_sauce_on_df}" |
awk '{ x += $0; } END { printf "%s %.2f %s", "TMPFS:", x*512/(1024**3), "GiB" }'
)
