When using the depot/build tool with the 'REBUILD=' argument as done by
the run tool's --depot-auto-update feature, the depot/build tool now
checks that an existing bin archive was indeed created via the src and
api archives present in the depot for the given version. This addresses
consistency issues when switching between different git branches that
refer to the same depot versions but with different content.
Fixes#5379
The depot tool 'build_bin_archive' used to ask only whether CCACHE is empty or
not and, if it wasn't empty, the tool added 'CCACHE := yes' to the build.conf
of the temporary build dir. This caused the sub-build processes to use ccache
even when the top-level CCACHE variable was set to a bogus value.
Also adds documentation of the CCACHE variable to the help message of the
'build' and 'build_bin_archive' tool.
Ref #4212
This commit complements issue #4004 with support for the depot/create
tool. If CCACHE=1 is specified at the command line, the build directory
for building a binary archive is configured with 'CCACHE := yes'.
This patch changes the depot layout such that each archive is
represented as a directory that contains the versions of the archive as
subdirectories.
Issue #2610
The depot tool did not consistently distinct libraries from regular
targets when handling binary archives. The binary archive of a regular
target is located at <user>/<bin>/<arch>/<name> whereas a library is
located at <user>/<bin>/<arch>/<api>/<name>.
Fixes#2438
