Promote verbose-build and log-lines
|
|
This allows commands like
nix build --log-lines 30 nixpkgs.hello
in order to obtain more information in case of a failure.

In structured-attributes derivations, you can now specify per-output
checks such as:
outputChecks."out" = {
# The closure of 'out' must not be larger than 256 MiB.
maxClosureSize = 256 * 1024 * 1024;
# It must not refer to C compiler or to the 'dev' output.
disallowedRequisites = [ stdenv.cc "dev" ];
};
outputChecks."dev" = {
# The 'dev' output must not be larger than 128 KiB.
maxSize = 128 * 1024;
};
Also fixed a bug in allowedRequisites that caused it to ignore
self-references.

$ nix-store -qR /nix/store/fnord

Fixes #2075.
|

Since its superclass RemoteStore::Connection contains 'to' and 'from'
fields that refer to the file descriptor maintained in the subclass,
it was possible for the flush() call in Connection::~Connection() to
write to a closed file descriptor (or worse, a file descriptor now
referencing another file). So make sure that the file descriptor
survives 'to' and 'from'.
|
|
For example, this prevents a "kvm" build on machines that don't have
KVM.
Fixes #2012.
|
|
This is primarily because Derivation::{can,will}BuildLocally() depends
on attributes like preferLocalBuild and requiredSystemFeatures, but it
can't handle them properly because it doesn't have access to the
structured attributes.
|
|
|
|
E.g. __noChroot and allowedReferences now work correctly. We also now
check that the attribute type is correct. For instance, instead of
allowedReferences = "out";
you have to write
allowedReferences = [ "out" ];
Fixes #2453.

This meant that making a typo in an s3:// URI would cause a bucket to
be created. Also it didn't handle eventual consistency very well. Now
it's up to the user to create the bucket.

* Don't wait forever for the client to remove data from the
buffer. This does mean that the buffer can grow without bounds
(e.g. when downloading is faster than writing to disk), but meh.
* Don't hold the state lock while calling the sink. The sink could
take any amount of time to process the data (in particular when it's
actually a coroutine), so we don't want to block the download
thread.

Otherwise, we just keep asking the substituter for other .narinfo
files, which can take a very long time due to retries/timeouts.

This happens on CIFS and means the remote filesystem has no extended
attributes.

TransferManager allocates a lot of memory (50 MiB by default), and it
might leak but I'm not sure about that. In any case it was causing
OOMs in hydra-queue-runner. So allocate only one TransferManager per
S3BinaryCacheStore.
Hopefully fixes https://github.com/NixOS/hydra/issues/586.

This callback is executed on a different thread, so exceptions thrown
from the callback are not caught:
Aug 08 16:25:48 chef hydra-queue-runner[11967]: terminate called after throwing an instance of 'nix::Error'
Aug 08 16:25:48 chef hydra-queue-runner[11967]: what(): AWS error: failed to upload 's3://nix-cache/19dbddlfb0vp68g68y19p9fswrgl0bg7.ls'
Therefore, just check the transfer status after it completes. Also
include the S3 error message in the exception.

This didn't work anymore since decompression was only done in the
non-coroutine case.
Decompressors are now sinks, just like compressors.
Also fixed a bug in bzip2 API handling (we have to handle BZ_RUN_OK
rather than BZ_OK), which we didn't notice because there was a missing
'throw':
if (ret != BZ_OK)
CompressionError("error while compressing bzip2 file");

It adds a new operation, cmdAddToStoreNar, that does the same thing as
the corresponding nix-daemon operation, i.e. call addToStore(). This
replaces cmdImportPaths, which has the major issue that it sends the
NAR first and the store path second, thus requiring us to store the
incoming NAR either in memory or on disk until we decide what to do
with it.
For example, this reduces the memory usage of
$ nix copy --to 'ssh://localhost?remote-store=/tmp/nix' /nix/store/95cwv4q54dc6giaqv6q6p4r02ia2km35-blender-2.79
from 267 MiB to 12 MiB.
Probably fixes #1988.

This is primarily useful for testing since it removes the need to have
SSH working.

libstore/gc.cc: ignore ESRCH when reading symlinks in /proc
|
|
readlink is also affected by the problem fixed for regular files in
c567afe355df
|

I hate to make this such a large check but the lack of documentation means we really have no idea what's allowed. All of them reported so far have been within ".app/Contents" directories. That appears to be a safe starting point. However, I would not be surprised to also find more paths that are disallowed for instance in .framework or .bundle directories.
Fixes #2031

This makes 'nix copy --to /mnt /nix/store/bla.drv' work.
|
|
The former is removed in C++17.
|
|
|
|
If a process disappears between the time /proc/[pid]/maps is opened and
the time it is read, the read() syscall will return ESRCH. This should be ignored.

I'm not sure if curl ever asks for enough data at once
for truncation to occur but better safe than sorry.

Don't say "download" when we mean "upload".
