2016-12-08 S3BinaryCacheStore: Ensure it only builds on LinuxEelco Dolstra1-0/+2
2016-12-08 Fix S3BinaryCacheStoreEelco Dolstra4-53/+11
It failed with AWS error uploading ‘6gaxphsyhg66mz0a00qghf9nqf7majs2.ls.xz’: Unable to parse ExceptionName: MissingContentLength Message: You must provide the Content-Length HTTP header. possibly because the istringstream_nocopy introduced in 0d2ebb4373e509521f27a6e8f16bfd39d05b2188 doesn't supply the seek method that the AWS library expects. So bring back the old version, but only for S3BinaryCacheStore.

2016-12-07 Add a hook to run diffoscope when non-determinism is detectedEelco Dolstra2-7/+33

2016-12-07 Add an option to make non-determinism non-fatalEelco Dolstra2-11/+24
That is, when build-repeat > 0, and the output of two rounds differ, then print a warning rather than fail the build. This is primarily to let Hydra check reproducibility of all packages.

This reverts commit f78126bfd6b6c8477fcdbc09b2f98772dbe9a1e7. There really is no need for such a massive change...

2016-11-16 seccomp: Forge return values for *chown32aszlig1-0/+4
These syscalls are only available in 32bit architectures, but libseccomp should handle them correctly even if we're on native architectures that do not have these syscalls. Signed-off-by: aszlig <aszlig@redmoonstudios.org>
2016-11-16 seccomp: Forge return codes for POSIX ACL syscallsaszlig2-1/+6
Commands such as "cp -p" also use fsetxattr() in addition to fchown(), so we need to make sure these syscalls always return successful as well in order to avoid nasty "Invalid value" errors. Signed-off-by: aszlig <aszlig@redmoonstudios.org>
2016-11-16 release.nix: Add a test for sandboxingaszlig2-0/+57
Right now it only tests whether seccomp correctly forges the return value of chown, but the long-term goal is to test the full sandboxing functionality at some point in the future. Signed-off-by: aszlig <aszlig@redmoonstudios.org>
2016-11-16 libstore/build: Forge chown() to return successaszlig1-0/+41
What we basically want is a seccomp mode 2 BPF program like this but for every architecture: BPF_STMT(BPF_LD+BPF_W+BPF_ABS, offsetof(struct seccomp_data, nr)), BPF_JUMP(BPF_JMP+BPF_JEQ+BPF_K, __NR_chown, 4, 0), BPF_JUMP(BPF_JMP+BPF_JEQ+BPF_K, __NR_fchown, 3, 0), BPF_JUMP(BPF_JMP+BPF_JEQ+BPF_K, __NR_fchownat, 2, 0), BPF_JUMP(BPF_JMP+BPF_JEQ+BPF_K, __NR_lchown, 1, 0), BPF_STMT(BPF_RET+BPF_K, SECCOMP_RET_ALLOW), BPF_STMT(BPF_RET+BPF_K, SECCOMP_RET_ERRNO) However, on 32 bit architectures we do have chown32, lchown32 and fchown32, so we'd need to add all the architecture blurb which libseccomp handles for us. So we only need to make sure that we add the 32bit seccomp arch while we're on x86_64 and otherwise we just stay at the native architecture which was set during seccomp_init(), which more or less replicates setting 32bit personality during runChild(). The FORCE_SUCCESS() macro here could be a bit less ugly but I think repeating the seccomp_rule_add() all over the place is way uglier. Another way would have been to create a vector of syscalls to iterate over, but that would make error messages uglier because we can either only print the (libseccomp-internal) syscall number or use seccomp_syscall_resolve_num_arch() to get the name or even make the vector a pair number/name, essentially duplicating everything again. Signed-off-by: aszlig <aszlig@redmoonstudios.org>
2016-11-16 Add build dependency for libseccompaszlig4-1/+16
We're going to use libseccomp instead of creating the raw BPF program, because we have different syscall numbers on different architectures. Although our initial seccomp rules will be quite small it really doesn't make sense to generate the raw BPF program because we need to duplicate it and/or make branches on every single architecture we want to suuport. Signed-off-by: aszlig <aszlig@redmoonstudios.org>
2016-11-16 Run builds as root in user namespace againaszlig1-29/+16
This reverts commit ff0c0b645cc1448959126185bb2fafe41cf0bddf. We're going to use seccomp to allow "cp -p" and force chown-related syscalls to always return 0. Signed-off-by: aszlig <aszlig@redmoonstudios.org>
2016-11-16 S3BinaryCacheStore:: Eliminate a string copy while uploadingEelco Dolstra4-3/+17
This cuts hydra-queue-runner's peak memory usage by about a third.
2016-11-14 buildPaths(): Handle ecIncompleteClosureEelco Dolstra1-1/+1
buildPaths() on a non-derivation would incorrectly not throw an error if the path didn't have a substitute.
2016-11-14 Don't rely on %mEelco Dolstra1-1/+2
2016-11-14 daemon: Do not error out when deduplication fails due to ENOSPC.Ludovic Courtès1-5/+19
This solves a problem whereby if /gnu/store/.links had enough entries, ext4's directory index would be full, leading to link(2) returning ENOSPC. * nix/libstore/optimise-store.cc (LocalStore::optimisePath_): Upon ENOSPC from link(2), print a message and return instead of throwing a 'SysError'.

Fix comments parsing
2016-11-13 Fix comments parsingGuillaume Maudoux3-1/+61
Fixed the parsing of multiline strings ending with an even number of stars, like /** this **/. Added test cases for comments.
2016-11-10 Store::computeFSClosure(): Support a set of pathsEelco Dolstra5-16/+25
This way, callers can exploits the parallelism of computeFSClosure() when they have multiple paths that they need the (combined) closure of.

Needed by Hydra.

2016-11-09 Implement backwards-compatible RemoteStore::addToStore()Eelco Dolstra3-3/+25
The SSHStore PR adds this functionality to the daemon, but we have to handle the case where the Nix daemon is 1.11. Also, don't require signatures for trusted users. This restores 1.11 behaviour. Fixes https://github.com/NixOS/hydra/issues/398.

2016-11-03 installation: allow profile modification to be skipped (#1072)Manav Rathi2-13/+25
The current behaviour modifies the first writeable file from amongst .bash_profile, .bash_login and .profile. So .bash_profile (if it is writable) would be modified even if a user has already sourced nix.sh in, say, .profile. This commit introduces a new environment variable, NIX_INSTALLER_NO_MODIFY_PROFILE. If this is set during installation, then the modifications are unconditionally skipped. This is useful for users who have a manually curated set of dotfiles that they are porting to a new machine. In such scenarios, nix.sh is already sourced at a place where the user prefers. Without this change, the nix installer would insist on modifying .bash_profile if it exists. This commit also add documentations for both the current behaviour and the new override.
2016-10-31 Support optional sandbox pathsEelco Dolstra2-10/+32
For example, you can now set build-sandbox-paths = /dev/nvidiactl? to specify that /dev/nvidiactl should only be mounted in the sandbox if it exists in the host filesystem. This is useful e.g. for EC2 images that should support both CUDA and non-CUDA instances.
