[Buildroot] [PATCH v4 0/7] PATH cleanup

[Buildroot] [PATCH v4 0/7] PATH cleanup

[Samuel Martin]

Hi all,

Another round for this series, with this time, as main change: the
renaming of BR2_PATH into BR_PATH, to follow what has been stated
during the last Buildroot developper metting.

Note that this series has been rebased on top of the next branch.

Yours,
Samuel

TARGET_MAKE_ENV already contains the PATH definition among other useful
variables.

[Buildroot] [PATCH v4 2/7] Makefile: introduce BR_PATH

[Samuel Martin]

Since the HOST_PATH and TARGET_PATH variables almost contain the same
things, let's factorize this in a single BR_PATH.

 This comment is redundant.

> +BR_PATH:="$(HOST_DIR)/bin:$(HOST_DIR)/usr/bin:$(HOST_DIR)/usr/sbin:$(PATH)"

 Use = instead of := and put spaces around it.

 Also, the quoting is really redundant. The original comment said "Quotes
are needed for spaces et al in path components", but since that was only
done for TARGET_PATH and not for HOST_PATH it didn't work in the first
place. In addition, we also don't add quotes around the other uses of
HOST_DIR etc., so it's just $(PATH) itself that we're protecting. If you
do keep the quotes, at least copy the comment.

 This comment is no longer in the right place.

[Buildroot] [PATCH v4 4/7] *.mk: replace (TARGET|HOST)_PATH by BR_PATH

[Samuel Martin]

Thanks to the 2 previous patches of the series, BR_PATH contains
all locations in which host-packages may install programs.

This patch replaces the occurrences TARGET_PATH and HOST_PATH with
BR_PATH, everywhere these variables are used in the *.mk files.

This can be useful for:
- package using custom build system that are not aware that the host
  tree is in $(O)/host/;
- post-{build,image} scripts, in case some host-tools were specifically
  built to be used by these scripts.

 This makes all the previous patches redundant, since the PATH=...
invocations should be removed instead of renamed.

 With this change, the := in BR_PATH becomes essential. There should be a
comment there to explain why. Also, the assignment to BR_PATH and to PATH
should be right next to each other (the export can stay here, though).

 And in fact, BR_PATH becomes completely redundant, it's sufficient to
have a single PATH := ....:$(PATH)

Agreed. Samuel, you should make a choice:

 * Either you use BR_PATH, and we continue to pass PATH=$(BR_PATH)
   whenever the PATH is needed.

 * Or you simply directly export PATH with the right value, and remove
   all occurrences where we manually pass PATH=<something>.

Thanks,

Thomas

Ok.
It was not clear whether the export would be accepted...
So I followed the secure way, thinking that the PATH usage could be
cleaned up later ;-)

Anyway, now it's my call. :)
Thanks for clarification.
