2017-11-06build: delay check for empty git submodule listDaniel P. Berrange1-7/+12
We short circuit the git submodule update when passed an empty module list. This accidentally causes the 'status' command to write to the status file. The test needs to be delayed into the individual commands to avoid this premature writing of the status file.

2017-11-06build: don't fail if given a git submodule which does not existDaniel P. Berrange1-2/+14
If going back in time in git history, across a commit that introduces a new submodule, the 'git-submodule.sh' script will fail, causing rebuild to fail. This is because config-host.mak contains a GIT_SUBMODULES variable that lists a submodule that only exists in the later commit. config-host.mak won't get repopulated until config.status is invoked, but make won't get this far due to the submodule error. This change makes 'git-submodule.sh' check whether each module is known to git and drops any which are not present. A warning message will be printed when any submodule is dropped in this manner.

2017-11-06build: allow automatic git submodule updates to be disabledDaniel P. Berrange1-0/+9
Some people building QEMU use VPATH builds where the source directory is on a read-only volume. In such a case 'scripts/git-submodules.sh update' will always fail and users are required to run it manually themselves on their original writable source directory. While this is already supported, it is nice to give users a command line flag to configure to permanently disable automatic submodule updates, as it means they won't get hard to diagnose failures from git-submodules.sh at an arbitrary later date. This patch thus introduces a flag '--disable-git-update' which will prevent 'make' from ever running 'scripts/git-submodules.sh update'. It will still run the 'status' command to determine if a submodule update is needed, but when it does this it'll simply stop and print a message instructing the developer what todo. eg $ ./configure --target-list=x86_64-softmmu --disable-git-update ...snip... $ make GEN config-host.h GEN trace/generated-tcg-tracers.h GEN trace/generated-helpers-wrappers.h GEN trace/generated-helpers.h GEN trace/generated-helpers.c GEN module_block.h GIT submodule checkout is out of date.

2017-11-06build: don't create temporary files in source dirDaniel P. Berrange1-4/+3
There are cases where users do VPATH builds with the source directory being on a read-only volume. In such a case they have to manually run the command 'git-submodule.sh ...modules...' ahead of time. When checking for status we should not then write into the source dir. Tested-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P.

2017-11-06build: allow setting a custom GIT binary for transparent proxyingDaniel P. Berrange1-5/+24
Some users can't run a bare 'git' command, due to need for a transparent proxying solution such as 'tsocks'. This adds an argument to configure to let users specify such a thing: ./configure --with-git="tsocks git" The submodule script is also updated to give the user a hint about using this flag, if we fail to checkout modules.

2017-10-16build: automatically handle GIT submodule checkout for dtcDaniel P. Berrange1-0/+38
Currently if DTC is required by configure and not available in the host OS install, we exit with an error message telling the user to checkout a git submodule or install the library. This introduces automatic handling of the git submodule checkout process and enables it for dtc. This only runs if building from GIT, so users of release tarballs still need the system library install. The current state of the git checkout is stashed in .git-submodule-status, and a helper program is used to determine if this state matches the desired submodule state. A dependency against 'Makefile' ensures that the submodule state is refreshed at the start of the build process Signed-off-by: Daniel P.
