Package P bypasses applying user patches (by not calling
default_src_prepare). I have patches I need to apply to P, and in this
case I really don't want to fork the ebuild. So, I'm hell bent on
doing it the hacky way with /etc/portage/bashrc (which, IIRC, I have
been told on this list not to do, but now I don't have much choice).
To make it work I need to know how the bashrc file is spliced into the
ebuild. For a given ebuild phase PH, does the bashrc code come before
the rest of PH, after PH, or does it replace PH? wiki and even the dev
guide are silent about this.

The usual example overrides "pre_src_prepare", which naturally is
executed before "src_prepare",
https://wiki.gentoo.org/wiki//etc/portage/patches#Enabling_.2Fetc.2Fportage.2Fpatches_for_all_ebuilds
With an extra line or two you can modify that code to check ${PN} to
avoid affecting other packages.

You do have a choice, use /etc/portage/env. here's one I have to patch a
specific version of a package
% cat env/app-cdr/cdrdao-1.2.3
post_src_unpack() {
cd "${S}"
epatch_user
}
You could also use post_src_prepare to apply the patch after any the
ebuild effects.

Again IIRC, when I tried using env for a similar purpose, it didn't work
at all, it seemed the only things valid in those files were variable
assignments. If possible, I would of course much prefer this way, as is
avoids an ugly switch on the package name.
Do you know what I could've been doing wrong? I think I brought it up
on the list, I'll try to dig up the thread.

Sounds about right... from `man portage`...
package.env
Per-package environment variable settings.
(moreover, we're using a custom parser IIRC and not all bash syntax will
work)

Are you mixing portage/env up with portage/package.env? The latter loads
conf files from env that contain variable assignments.

I don't think I'm mixing them up: one of them is a directory, so hardly
can contain any code at all ;-)
(Well, the other _can_ also be a directory, but YSWIM).

Both are directories here, so it would be easy to confuse them.

I've just had to use this again, for the vcdimager ebuild to apply the
patch https://bugs.gentoo.org/638646 - the ebuild doesn't apply patches
in /etc/portage/patches but it did when I created this file
% cat /etc/portage/env/media-video/vcdimager-0.7.24
post_src_unpack() {
cd "${S}"
epatch_user
}

That came up in the OP, but the question was about doing it for selected
ebuilds, which is exactly what this must shorter option does.

Ah, now I see why I was so confused. the /etc/portage/env/ directory
serves two purposes, only distantly related:
- houses the environment files, referenced from /etc/portage/package.env
These can apparantly contain only variable settings.
- houses the package specific bashrc files, as $CATEGORY/$PN and so on.
These can contain hook definitions and perhaps even more general shell
code.
Both man portage(5) and the wiki treat the two cases separately, so the
fact that the ultimate data files are in the same directory is lost on
the careless reader (such as me). Michael or Neil, if you do edit the
docs please improve this aspect.
