Reproduction case for a bug we discovered in the past; Dune was
|
||
|
|
storing the wrong stats for generated files in the digest cache and as
|
||
|
|
a result was always re-hashing all files in the build directory on the
|
||
|
|
second run.
|
||
|
|
|
||
|
|
More precisely, we were using the stats of the file before making it
|
||
|
|
read-only.
|
||
|
|
|
||
|
|
|
||
|
|
$ echo '(lang dune 3.0)' > dune-project
|
||
|
|
$ touch x y z
|
||
|
|
$ dune build x y z --wait-for-filesystem-clock
|
||
|
|
|
||
|
|
Check that the next build rehashes nothing:
|
||
|
|
|
||
|
|
$ dune build x y z --wait-for-filesystem-clock --debug-digests 2>&1 | sed 's/stats = { .*\( perm = [0-9]*\).*}/stats = {\1; ... }/'
