-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi,
On behalf of the Lisp project (which includes the Emacs subproject) I'd like to propose that preservation of mtimes be included as a requirement of EAPI3. An EAPI bump may not be really necessary for this - after all we're just specifying previously unspecified behavior - but it will help Paludis. Portage already supports this, and according to my information pkgcore too, but unfortunately not paludis. More details on the bug mentioned below. Background: Dynamic languages such as Common Lisp and Elisp, but also python (and ruby?) compile source files to some form which loads and executes faster; in Lisp-speak these are called fasl's (for FASt Load), for python these are the pyc files. Need for recompilation is determined by comparing the mtimes of the original source and the fasl. Both source and fasl are usually installed. If the mtimes are modified such that the fasl is not newer than the original source anymore then implementations will attempt to recompile these sources and will try to write the output alongside the sources. This will cause a sandbox violation if it happens in an ebuild or fail due to permissions when done as a user. See also: https://bugs.gentoo.org/264130 "PMS should require that file mtimes are preserved on merge"; Gentoo Hosted Projects, PMS/EAPI; NEW; u...@g.o:pms-b...@g.o Marijn - -- Gods do not want you to think, lest they lose existence. Religions do not want you to think, lest they lose power.
