Fix RemoteStore::addToStore() latency
2020-07-29 10:04:26 +02:00
Matthew Bauer fa8515d7ec Set regex_constants::match_continuous for quicker search
match_continuous limits the search to the current start position,
instead of searching the entire file.

On libc++, this improves performance dramatically:

Eelco Dolstra 4c0077a07d Fix RemoteStore::addToStore() latency
Since 6185d25e52, this was very
latency-bound since it required a round-trip for every 32 KiB. So for
example copying a 514 MiB closure over a virtual ethernet device with
a articial delay of just 1 ms took 343s. Now it takes 2.7s.

Fixes #3372.

Restore backwards-compat for current builtins.fetchGit
If a repo is dirty, it used to return a `rev` object with an "empty"
sha1 (0000000000000000000000000000000000000000). Please note that this
only applies for `builtins.fetchGit` and *not* for `builtins.fetchTree{
type = "git"; }`.

istream->tellg() returns -1 so we can't get the number of bytes

Merge legacy fetchGit-builtin with the generic fetchTree-function
The original idea was to implement a git-fetcher in Nix's core that
supports content hashes[1]. In #3549[2] it has been suggested to
actually use `fetchTree` for this since it's a fairly generic wrapper
over the new fetcher-API[3] and already supports content-hashes.

This patch implements a new git-fetcher based on `fetchTree` by
incorporating the following changes:

* Removed the original `fetchGit`-implementation and replaced it with an
  alias on the `fetchTree` implementation.

* Ensured that the `git`-fetcher from `libfetchers` always computes a
  content-hash and returns an "empty" revision on dirty trees (the
  latter one is needed to retain backwards-compatibility).

* The hash-mismatch error in the fetcher-API exits with code 102 as it
  usually happens whenever a hash-mismatch is detected by Nix.

* Removed the `flakes`-feature-flag: I didn't see a reason why this API
  is so tightly coupled to the flakes-API and at least `fetchGit` should
  remain usable without any feature-flags.

* It's only possible to specify a `narHash` for a `git`-tree if either a
  `ref` or a `rev` is given[4].

* It's now possible to specify an URL without a protocol. If it's missing,
  `file://` is automatically added as it was the case in the original
  `fetchGit`-implementation.

Matthew Bauer 72f8771094 Allow PRECOMPILE_HEADERS in cross-compilation
In cross, CXX will look like aarch64-unknown-linux-gnu-g++. We could
run some command to check what kind of compiler it is, but for now we
can just check if g++ is anywhere in the string. I couldn’t find any
"ends with" for makefile, so it can be anywhere in CXX.

John Ericson 2274f63453 Get rid of basicDerivation::findOutput
It's a tiny function which is:

 - hardly worth abstrating over, and also only used once.

 - doesn't work once we get CA drvs

I rewrote the one callsite to be forwards compatable with CA
derivations, and also potentially more performant: instead of reading in
the derivation it can ust consult the SQLite DB in the common case.
