Eelco Dolstra 201b48de60 Add an HTTP binary cache store 
Allowing stuff like

  NIX_REMOTE=https://cache.nixos.org nix-store -qR /nix/store/x1p1gl3a4kkz5ci0nfbayjqlqmczp1kq-geeqie-1.1

or

  NIX_REMOTE=https://cache.nixos.org nix-store --export /nix/store/x1p1gl3a4kkz5ci0nfbayjqlqmczp1kq-geeqie-1.1 | nix-store --import

at runtime.

Eelco Dolstra 6055d84beb Fix reading symlinks 
The st_size field of a symlink doesn't have to be correct, e.g. for
/dev/fd symlinks.

Eelco Dolstra cca4a8dc1a 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.
 2016-03-02 15:46:07 +01:00
Eelco Dolstra 00b2c05749 nix: Add commands to query contents of NARs / binary caches 
For example,

  $ NIX_REMOTE=file:///my-cache nix ls-store -lR /nix/store/f4kbgl8shhyy76rkk3nbxr0lz8d2ip7q-binutils-2.23.1
  dr-xr-xr-x                    0 ./bin
  -r-xr-xr-x                30748 ./bin/addr2line
  -r-xr-xr-x                66973 ./bin/ar
  ...

Similarly, "nix ls-nar" lists the contents of a NAR file, "nix
cat-nar" extracts a file from a NAR file, and "nix cat-store" extract
a file from a Nix store.

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 28e7e29abd Eliminate reserveSpace flag 2016-02-24 17:44:55 +01:00
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 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.
 2016-02-24 11:39:56 +01:00
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.

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.
 2016-02-15 21:45:56 +01:00
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.
