446 | # @FUNCTION: epatch_user |
|
|
447 | # @USAGE: |
|
|
448 | # @DESCRIPTION: |
|
|
449 | # Applies user-provided patches to the source tree. The patches are |
|
|
450 | # taken from /etc/portage/patches/<CATEGORY>/<PF|P|PN>/, where the first |
|
|
451 | # of these three directories to exist will be the one to use, ignoring |
|
|
452 | # any more general directories which might exist as well. |
|
|
453 | # |
|
|
454 | # User patches are intended for quick testing of patches without ebuild |
|
|
455 | # modifications, as well as for permanent customizations a user might |
|
|
456 | # desire. Obviously, there can be no official support for arbitrarily |
|
|
457 | # patched ebuilds. So whenever a build log in a bug report mentions that |
|
|
458 | # user patches were applied, the user should be asked to reproduce the |
|
|
459 | # problem without these. |
|
|
460 | # |
|
|
461 | # Not all ebuilds do call this function, so placing patches in the |
|
|
462 | # stated directory might or might not work, depending on the package and |
|
|
463 | # the eclasses it inherits and uses. It is safe to call the function |
|
|
464 | # repeatedly, so it is always possible to add a call at the ebuild |
|
|
465 | # level. The first call is the time when the patches will be |
|
|
466 | # applied. |
|
|
467 | # |
|
|
468 | # Ideally, this function should be called after gentoo-specific patches |
|
|
469 | # have been applied, so that their code can be modified as well, but |
|
|
470 | # before calls to e.g. eautoreconf, as the user patches might affect |
