Eelco Dolstra 581e1bc5b4 FdSource: track number of bytes read 2016-02-26 16:16:08 +01:00
Eelco Dolstra bcc9943cee importPaths(): Optionally add NARs to binary cache accessor
This enables an optimisation in hydra-queue-runner, preventing a
download of a NAR it just uploaded to the cache when reading files
like hydra-build-products.
2016-02-26 15:20:10 +01:00
Eelco Dolstra 1042c10fd0 Add NAR / Store accessor abstraction
This is primary to allow hydra-queue-runner to extract files like
"nix-support/hydra-build-products" from NARs in binary caches.

Eelco Dolstra 152b1d6bf9 deletePath(): Succeed if path doesn't exist
Also makes it robust against concurrent deletions.

Eelco Dolstra 5a64e66268 LocalStore::addTextToStore(): Don't read the path we just wrote
This eliminates some unnecessary (presumably cached) I/O.

Eelco Dolstra 9ccbd55c5b BinaryCacheStore: Implement addToStore()
So now you can do

  $ NIX_REMOTE=file:///tmp/binary-cache nix-instantiate '<nixpkgs>' -A hello

and lots of other operations.

Eelco Dolstra 263187a2ec Move BinaryCacheStore / LocalBinaryCacheStore from Hydra
So you can now do:

  $ NIX_REMOTE=file:///tmp/binary-cache nix-store -qR /nix/store/...

Eelco Dolstra 5f862658c3 Remove bad daemon connections from the pool
This is necessary for long-running processes like hydra-queue-runner:
if a nix-daemon worker is killed, we need to stop reusing that
connection.

Scott Olson 6498adb002 Throw a specific error for incomplete parse errors.
`nix-repl` will use this for deciding whether to keep waiting for input or
error out right away.

Eelco Dolstra e292144d46 RemoteStore: Make thread-safe
This allows a RemoteStore object to be used safely from multiple
threads concurrently. It will make multiple daemon connections if
necessary.

Note: pool.hh and sync.hh have been copied from the Hydra source tree.

OpenSSL can randomly segfault unless we register a callback function
to do locking.

Eelco Dolstra d361901bfe curl: Set CURLOPT_NOSIGNAL
Otherwise using curl is not safe in multi-threaded applications
because it installs a SIGALRM handler.

Eelco Dolstra c4d22997f3 Add C++ functions for .narinfo processing / signing
This is currently only used by the Hydra queue runner rework, but like
eff5021eaa it presumably will be useful
for the C++ rewrite of nix-push and
download-from-binary-cache. (@shlevy)

Eelco Dolstra eff5021eaa Add xz compression function
This is used by the Hydra queue runner, but since it may also be
useful for the C++ rewrite of nix-push, I'm putting it here.

Eelco Dolstra bfdacb712c decompressXZ: Ensure that lzma_end() is called
Otherwise we might leak memory.

Eelco Dolstra e03d6e0998 Fix broken number parsing in fromJSON
The call to tmp_number.append had its arguments mixed up. Also, JSON
does not allow a trailing "," after array/object members.

Eelco Dolstra fa7cd5369b StoreAPI -> Store
Calling a class an API is a bit redundant...
2016-02-04 14:48:42 +01:00
Eelco Dolstra c10c61449f Eliminate the "store" global variable
Also, move a few free-standing functions into StoreAPI and Derivation.

Also, introduce a non-nullable smart pointer, ref<T>, which is just a
wrapper around std::shared_ptr ensuring that the pointer is never
null. (For reference-counted values, this is better than passing a
"T&", because the latter doesn't maintain the refcount. Usually, the
caller will have a shared_ptr keeping the value alive, but that's not
always the case, e.g., when passing a reference to a std::thread via
std::bind.)

Eelco Dolstra d367b8e787 Add build mode to compute fixed-output derivation hashes
For example,

  $ nix-build --hash -A nix-repl.src

will build the fixed-output derivation nix-repl.src (a fetchFromGitHub
call), but instead of *verifying* the hash given in the Nix
expression, it prints out the resulting hash, and then moves the
result to its content-addressed location in the Nix store. E.g

  build produced path ‘/nix/store/504a4k6zi69dq0yjc0bm12pa65bccxam-nix-repl-8a2f5f0607540ffe56b56d52db544373e1efb980-src’ with sha256 hash ‘0cjablz01i0g9smnavhf86imwx1f9mnh5flax75i615ml71gsr88’

The goal of this is to make all nix-prefetch-* scripts unnecessary: we
can just let Nix run the real thing (i.e., the corresponding fetch*
derivation).

Another example:

  $ nix-build --hash -E 'with import <nixpkgs> {}; fetchgit { url = "https://github.com/NixOS/nix.git"; sha256 = "ffffffffffffffffffffffffffffffffffffffffffffffffffff"; }'
  ...
  git revision is 9e7c1a4bbd
  ...
  build produced path ‘/nix/store/gmsnh9i7x4mb7pyd2ns7n3c9l90jfsi1-nix’ with sha256 hash ‘1188xb621diw89n25rifqg9lxnzpz7nj5bfh4i1y3dnis0dmc0zp’

(Having to specify a fake sha256 hash is a bit annoying...)
