Show what Dune watches via inotify
|
|
|
|
$ mkdir test
|
|
$ cd test
|
|
|
|
$ echo '(lang dune 3.0)' > dune-project
|
|
$ mkdir src
|
|
$ echo '(library (name foo))' > src/dune
|
|
$ touch src/a.ml
|
|
$ touch src/b.ml
|
|
|
|
$ strace -o ../log -e inotify_add_watch dune build --passive-watch-mode &
|
|
Success, waiting for filesystem changes...
|
|
|
|
$ dune rpc build --wait .
|
|
Success
|
|
$ dune shutdown
|
|
$ wait
|
|
|
|
The pattern below excludes absolute files as Dune currently watches
|
|
everything in the PATH, which is not very reproducible.
|
|
|
|
$ sed -nE 's/inotify_add_watch\([0-9]*, "([^/].*)", .*\) (=.*)/watch \1 \2/p' ../log | sort -u
|
|
watch . = 2
|
|
watch _build/.sync = 1
|
|
watch src = 3
|
|
|
|
Since the pattern above is not reproducible, uncomment the next lines
|
|
to see what it is really doing
|
|
# $ sed -nE 's/inotify_add_watch\([0-9]*, "(.*)", .*\) (=.*)/watch \1 \2/p' ../log | sort -u -k4n -k2 | sed "s,$OPAM_SWITCH_PREFIX,OPAM_SWITCH_PREFIX," | sed "s,$DUNE_SOURCEROOT,DUNE_SOURCEROOT,"
|
|
# watch _build/.sync = 1
|
|
# watch . = 2
|
|
# watch src = 3
|
|
# watch DUNE_SOURCEROOT/_build/default/test/blackbox-tests/test-cases/.bin = 4
|
|
# watch DUNE_SOURCEROOT/_build/install/default/bin = 5
|
|
# watch OPAM_SWITCH_PREFIX/bin = 6
|

# watch OPAM_SWITCH_PREFIX/lib/ocaml = 7
