[Buildroot] [PATCH 0 of 6 resend] Improve support for custom external toolchains (and related changes)

[Thomas De Schampheleire]

The main intention for this patch series is to allow downloading a custom
external toolchain. I had previously added this functionality to buildroot
(did not make it to mainstream, I should have followed it up better) and
have been using it for about a year now.
I have now lined it up with current buildroot, updated based on the
comments of ThomasP, and fixed some related problems I found along the
way.

Thomas De Schampheleire (6):
       pkg-download.mk: allow using localfiles outside of package infrastructure
       pkg-download.mk: use stripurischeme function in localfiles download method
       pkg-download.mk: support detection of URI schemes in DOWNLOAD
       toolchain-external/Config.in: fix indentation
       toolchain-external: allow downloading a custom toolchain
       toolchain-external: line up comments with reality

[Buildroot] [PATCH 1 of 6 resend] pkg-download.mk: allow using localfiles outside of package infrastructure

[Thomas De Schampheleire]

The localfiles download method uses $($(PKG)_SITE))) and
$($(PKG)_SOURCE) instead of $(1) and $(2). This means that it can only
be used for package downloads (through gentargets, autotargets, ...)
and not for other downloads like external toolchains.

This patch changes localfiles to allow this, just as the wget and scp
download methods already did.
For the version control download methods, nothing changes.

  Is there any reason not to do it for the VCS download methods?

  Shouldn't this be
		$(LOCALFILES) $(call qstrip,$(subst file://,,$(1))) $(DL_DIR)/$(2)

Thanks for your review and acks.

Just because I didn't really see how you'd use that. For non-package
downloads you'd be downloading a single file (typically a tarball). It
seems odd to me to take that from a version control system. I guess you'll
need to express the version you want in the URL, which may not be possible
for all the systems we support.
Thomas basically asked the same question. Do any of you do see a use case?

Well, the behavior is the same as before. But I guess you could safely add
the explicit destination. I can't test it as I'm on holiday, though.

Maybe you could submit that as a separate patch?

  It's just for symmetry as far as I'm concerned.  It's true that the VCS
methods require a revision as well, so they'll also require the $(PKG) to
be used.

  Taking a tarball from a VCS is not even possible with the current VCS
download methods: they would pack the tarball into another tarball...

[Buildroot] [PATCH 3 of 6 resend] pkg-download.mk: support detection of URI schemes in DOWNLOAD

[Thomas De Schampheleire]

When using one of the package infrastructures, the DOWNLOAD function
uses $(PKG)_SITE_METHOD to determine the appropriate download method,
which is autodetected based on the URI if none was explicitly set.

When the DOWNLOAD function is called directly, for example when
downloading a toolchain, or from a package that does not use one of
the package infrastructures, the SITE_METHOD is not autodetected,
and thus the download defaults to wget.

This patch adds URI scheme detection directly to the DOWNLOAD method,
in case no SITE_METHOD was detected yet.

  Maybe the default definition of PKG_SITE_METHOD can be removed then?

[Buildroot] [PATCH 5 of 6 resend] toolchain-external: allow downloading a custom toolchain

[Thomas De Schampheleire]

This patch adds the possibility to download a custom external
toolchain, in addition to the existing support of preinstalled custom
external toolchains.

With the modified configuration, the user is presented with the
following options:
- Toolchain type: Buildroot toolchain | External toolchain | Ct-ng toolchain

In case of External toolchain:
- Toolchain: the CodeSourcery toolchains | Custom toolchain
- Toolchain origin: Toolchain to be downloaded and installed | Pre-installed toolchain

In case of Toolchain to be downloaded, the user is presented with:
- Toolchain URL
In case of Pre-installed toolchain, the users sees:
- Toolchain Path

For CodeSourcery toolchains, the toolchain URL field is not used (the
URLs are directly coded in ext-tool.mk).

This feature was proposed previously [1] with some comments by Thomas
Petazzoni. At that time, the proposed split was to have 'custom pre-
installed toolchain' and 'custom downloadable toolchain' sit alongside
the CodeSourcery ones, as such providing a clear distinction between
pre-installed and downloaded custom toolchains. However, during
implementation I felt that this structure makes the code more complex
than it needs to be and so I choose for an alternative solution that
IMO still creates a clear distinction. Any comments are of course
welcome.
