Taeer Bar-Yam bd8571a5c3 add explanation and test 2022-11-23 12:06:47 -05:00
Taeer Bar-Yam b13fd4c58e Fix why-depends for CA derivations 
why-depends assumed that we knew the output path of the second argument.
For CA derivations, we might not know until it's built. One way to solve
this would be to build the second installable to get the output path.

In this case we don't need to, though. If the first installable (A)
depends on the second (B), then getting the store path of A will
necessitate having the store path B. The contrapositive is, if the store
path of B is not known (i.e. it's a CA derivation which hasn't been
built), then A does not depend on B.

Eelco Dolstra 3d23b9d032 SimpleUserLock::getSupplementaryGIDs(): Filter out main gid 
This avoids having the user's gid in the supplementary group list as
well.

Eelco Dolstra b37c2d84b6 Always call setgroups() 
We shouldn't skip this if the supplementary group list is empty,
because then the sandbox won't drop the supplementary groups of the
parent (like "root").

Eelco Dolstra 128910ba23 Separate cgroup support from auto-uid-allocation 
The new experimental feature 'cgroups' enables the use of cgroups for

resource limits and getting some build stats.

Robert Hensing 7e162c69fe derivation-goal: Fix requires non-existing output error 
It occurred when a output of the dependency was already available,
so it didn't need rebuilding and didn't get added to the
inputDrvOutputs.
This process-related info wasn't suitable for the purpose of finding
the actual input paths for the builder. It is better to do this in
absolute terms by querying the store.

libstore: link to aws-crt-cpp 
This change is needed to support aws-sdk-cpp 1.10 and newer.

I opted not to make this dependent on the sdk version because
the crt dependency has been in the interface of the older
sdk as well, and it was only coincidence that libstore didn't
make use of any privately defined symbols directly.

Restrict readFile context to references that appear in the string 
When calling `builtins.readFile` on a store path, the references of that
path are currently added to the resulting string's context.

This change makes those references the *possible* context of the string,
but filters them to keep only the references whose hash actually appears
in the string, similarly to what is done for determining the runtime
references of a path.
