[PATCH 0/2] kbuild: Fix install errors when INSTALL_PATH does not exist

[PATCH 0/2] kbuild: Fix install errors when INSTALL_PATH does not exist

[Zhang Bingwu]

From: Zhang Bingwu <xtexchooser@duck.com>

When running 'make zinstall INSTALL_PATH=somepath'
 where 'somepath' does not exist, the install
 scripts (install.sh) print error messages
 but also return a success status code.
This will make 'make' regard 'install' (and 'zinstall', etc)
 succeeded.
When there are also other targets at the same time,
 for example, 'make zinstall dtbs_install modules_install',
 make will keep going on and other outputs will fill stdout,
 and make the error message hard to find.

dtbs_install and modules_install creates the target directory
 if it does not exist. install, zinstall and others should
 have the same behaviour.

If INSTALL_PATH is not a valid directory, we should create it.
If the installation process still fails with errors, for example,
 insufficient space on disk or permission denied, make should regard
 the install target failed, stop as soon as possible,
 and exit with error.

[PATCH 1/2] kbuild: Abort make on install failures

[Zhang Bingwu]

From: Zhang Bingwu <xtexchooser@duck.com>

Setting '-e' flag tells shells to exit with error exit code immediately
after any of commands fails, and causes make(1) to regard recipes as
failed.

Before this, make will still continue to succeed even after the
installation failed, for example, for insufficient permission or
directory does not exist.

What about #!/bin/sh -e on the first line, which is the more normal way
to do this for an entire script?

are you sure?  I can find many more occurrences of 'set -e' than the
shebang version in the Linux tree, especially in the kbuild scripts, thus
it's bike-shedding, isn't it?

When you put -e on the shebang line, like

    #!/bin/sh -e

the option -e is set when you do:

    $ arch/arm/boot/install.sh


But, -e is not set when you do:

    $ sh arch/arm/boot/install.sh



The reason is obvious because the latter case
does not use the shebang line.




In Kbuild, some places run the script directly like the former case,
and others use CONFIG_SHELL like

   $(CONFIG_SHELL) arch/arm/boot/install.sh


The inconsistency is not nice, but that is a different issue.


The separate 'set -e' statement works for both cases,
so I think this is safer, though it is kind of bike-shedding.

Thanks!
I also think it is safer to use 'set -e' in the case of 'sh install.sh',
 so I support not to use 'sh -e' in the shebang line. The planned V2 patch for 
this disappeared.
