Some context: I'm trying to build Go 1.10 under slapos and get failures like: ok os 0.782s PASS testing: can't write /tmp/go-build511454695/b682/testlog.txt: write /tmp/go-build511454695/b682/testlog.txt: broken pipe FAIL os/exec 0.947s ... ok cmd/vet/internal/cfg 0.002s 2018/04/03 18:13:29 Failed: exit status 1 golang1.10: Command failed with exit code 1: cd src && ls -l /proc/self/fd && ./all.bash && cp -alf .. /srv/slapgrid/slappart5/srv/runner/software/099a7368550e95d120639cb03b6d47c8/parts/golang1.10 golang1.10: Compilation error. The package is left as is at /srv/slapgrid/slappart5/srv/runner/software/099a7368550e95d120639cb03b6d47c8/parts/golang1.10__compile__/go where you can inspect what went wrong While: Installing golang1.10. Error: System error This was traced to https://github.com/golang/go/issues/24285, which in turn was traced by me to the fact that golang os/exec tests close all file descriptors > 4 assuming that only stdin, stdout, stderr, epoll and testlog file descriptors are there: https://github.com/golang/go/blob/26e0e8a840/src/os/exec/exec_test.go#L402 https://github.com/golang/go/blob/26e0e8a840/src/os/exec/exec_test.go#L415 However when go build is run under slapos it starts with the following descriptors inherited in the environment: lr-x------ 1 slapuser5 slapuser5 64 Apr 3 17:57 0 -> pipe:[2969903608] l-wx------ 1 slapuser5 slapuser5 64 Apr 3 17:57 1 -> pipe:[2969903609] l-wx------ 1 slapuser5 slapuser5 64 Apr 3 17:57 2 -> pipe:[2969903609] l-wx------ 1 slapuser5 slapuser5 64 Apr 3 17:57 3 -> /srv/slapgrid/slappart5/srv/runner/software.log i.e. the file descriptor for software.log (under `slapos node software`) is passed opened to spawned buildout commands -> and oops - go build failure. I'm not saying go behaviour is correct. However for slapos it is also not good to leak e.g. log file descriptors to spawned processes (e.g. what if spawned child writes there by mistake?). Since fixing on Go side is not very easy, because it will probably require non-small testing infrastructure refactoring, I decided to fix on SlapOS side, because it is a) easier, and b) correct & good to do in any way. ---- To fix we just pass close_fds=True to subprocess.Popen run from under SlapPopen, which means that popen will close all file descriptors besides stdin, stdout & stderr for child. close_fds default is already True for python3 https://www.python.org/dev/peps/pep-0433/#subprocess-close for the reason that it is frequent mistake for programmers to not leak file descriptors to spawned processes. However on python2, which we are still using, close_fds default is False. So let's fix the default on our side. /reviewed-by @jerome, @rafael /reviewed-on nexedi/slapos.core!42

Hiding such environment variable prevent easy access to the user owning the software or the user owning the instance. Some instances needs to have the actual username of the instance in their config files and some softwares needs access to the username of user building the software. This is - in theory - easy to do in zc.buildout thanks to https://collective.github.io/collective.recipe.grp/ , but the way slapos run buildout with some environment variables hidden made it not possible. Fixes [#20180402-716ACB](https://nexedi.erp5.net/bug_module/20180402-716ACB/) /reviewed-on !41

python promises can define sense, test and anomaly method. test method will be called by slapgrid or when no bang is needed for the promise anomaly method is called when a promise failure required to bang the master, anomaly method can be optional but it's not the case for test method. Slapgrid always run promises and save the result in .slapgrid/promise/result in a JSON format. The result will be used later by monitor When a partition is correctly deployed, slapgrid will only run promise anomaly and will bang if there is an error and if the failed promise can bang check promise anomaly when partition is upto date
