Aleksandr, Aleksandr Vityazev 写道: > * gnu/packages/boost (boost-signals2): [source]: Update hash. Thanks! Hash changes happen… ‘but they shouldn't’. Commit messages should not imply that they're routine. The diff is quite significant: $ git diff 10b030be782b979509cee15e0f0afde59d2f9581..\ 4a51d6e47230123d413cbecb19eb94f195301b8e | wc -l 1829 We should record the two commits in the change log. 10b030b is from October 2019. Boost 1.77.0 wasn't released until August 2021[0]. The boost-1.77.0 tag hasn't been moved from 4a51d6e since June 2021. It seems likely that upstream creates boost-X.Y.Z tags targetting unreleased future Boost versions, moves them freely, but stops once that Boost version is released. That's something we could document in a comment, at least. I'll ask for confirmation on their bug tracker. Only two formatting nitpicks: > gnu: boost-signals2: Update hash Missing ‘.’. > * gnu/packages/boost (boost-signals2): [source]: Update hash. Drop the first ‘: ’. Pushed as 04b6e1ed265e64a004c7ea93018179785b979f31 with those changes. Kind regards, T G-R [0]: https://lists.boost.org/boost-announce/2021/08/0593.php
