2017-09-08	Communicate the structured log FD to builders	Eelco Dolstra
	Since we may use a dedicated file descriptor in the future, this allows us to change it. So builders can do if [[ -n $NIX_LOG_FD ]]; then echo "@nix { message... }" >&$NIX_LOG_FD fi
2017-09-06	Fix abort when the GC thread gets an exception	Eelco Dolstra

2017-09-05	Add automatic garbage collection	Eelco Dolstra
	Nix can now automatically run the garbage collector during builds or while adding paths to the store. The option "min-free = <bytes>" specifies that Nix should run the garbage collector whenever free space in the Nix store drops below <bytes>. It will then delete garbage until "max-free" bytes are available. Garbage collection during builds is asynchronous; running builds are not paused and new builds are not blocked. However, there also is a synchronous GC run prior to the first build/substitution. Currently, no old GC roots are deleted (as in "nix-collect-garbage -d").
2017-09-05	GC: Don't delete own temproots file	Eelco Dolstra
	Since file locks are per-process rather than per-file-descriptor, the garbage collector would always acquire a lock on its own temproots file and conclude that it's stale.
2017-09-01	Abort curl downloads if there is no progress for 5 minutes	Eelco Dolstra
	Maybe this will fix the curl hangs on macOS. (We could also use CURLOPT_TIMEOUT but that seems more of a sledgehammer.)
2017-08-31	Call queryMissing() prior to building	Eelco Dolstra
	Without this, substitute info is fetched sequentially, which is superslow. In the old UI (e.g. nix-build), we call printMissing(), which calls queryMissing(), thereby preheating the binary cache cache. But the new UI doesn't do that.
2017-08-31	Add an activity for binary cache queries	Eelco Dolstra

2017-08-31	Rename a few configuration options	Eelco Dolstra
	In particular, drop the "build-" and "gc-" prefixes which are pointless. So now you can say nix build --no-sandbox instead of nix build --no-build-use-sandbox
2017-08-28	Give activities a verbosity level again	Eelco Dolstra
	And print them (separately from the progress bar) given sufficient -v flags.
2017-08-28	Don't send progress messages to older clients	Eelco Dolstra

2017-08-28	Tunnel progress messages from the daemon to the client	Eelco Dolstra
	This makes the progress bar work for non-root users.
2017-08-25	Simplify	Eelco Dolstra

2017-08-25	Allow derivations to update the build phase	Eelco Dolstra
	So the progress bar can show [1/0/1 built, 0.0 MiB DL] building hello-2.10 (configuring): checking whether pread is declared without a macro... yes
2017-08-25	Allow activities to be nested	Eelco Dolstra
	In particular, this allows more relevant activities ("substituting X") to supersede inferior ones ("downloading X").
2017-08-25	Restore activity metadata	Eelco Dolstra
	This allows the progress bar to display "building perl-5.22.3" instead of "building /nix/store/<hash>-perl-5.22.3.drv".
2017-08-21	Clean up JSON construction	Eelco Dolstra

2017-08-21	Allow builders to create activities	Eelco Dolstra
	Actually, currently they can only create download activities. Thus, downloads by builtins.fetchurl show up in the progress bar.
2017-08-16	nix optimise-store: Show how much space has been freed	Eelco Dolstra

2017-08-16	nix optimise-store: Add	Eelco Dolstra
	This replaces "nix-store --optimise". Main difference is that it has a progress indicator.
2017-08-16	Progress indicator: Cleanup	Eelco Dolstra

2017-08-16	Progress indicator: More improvements	Eelco Dolstra

2017-08-16	Progress indicator: Show number of active items	Eelco Dolstra

2017-08-16	Progress indicator: Unify "copying" and "substituting"	Eelco Dolstra
	They're the same thing after all. Example: $ nix build --store local?root=/tmp/nix nixpkgs.firefox-unwrapped [0/1 built, 49/98 copied, 16.3/92.8 MiB DL, 55.8/309.2 MiB copied] downloading 'https://cache.nixos.org/nar/0pl9li1jigcj2dany47hpmn0r3r48wc4nz48v5mqhh426lgz3bz6.nar.xz'
2017-08-16	Improve substitution progress indicator	Eelco Dolstra
	E.g. $ nix build --store local?root=/tmp/nix nixpkgs.firefox-unwrapped [0/1 built, 1/97/98 fetched, 65.8/92.8 MiB DL, 203.2/309.2 MiB copied] downloading 'https://cache.nixos.org/nar/1czm9fk0svacy4h6a3fzkpafi4f7a9gml36kk8cq1igaghbspg3k.nar.xz'
2017-08-16	nix copy: Improve progress indicator	Eelco Dolstra
	It now shows the amount of data copied: [8/1038 copied, 160.4/1590.9 MiB copied] copying path '...'
2017-08-16	nix copy: Revive progress bar	Eelco Dolstra

2017-08-16	Disallow SSH host names starting with a dash	Eelco Dolstra

2017-08-10	Style fix	Eelco Dolstra

2017-08-09	Use /proc/self/fd to efficiently close all FDs on Linux	Eelco Dolstra
	Issue #1506.
2017-07-31	Merge branch 'macOS' of https://github.com/davidak/nix	Eelco Dolstra

2017-07-30	Replace Unicode quotes in user-facing strings by ASCII	Jörg Thalheim
	Relevant RFC: NixOS/rfcs#4 $ ag -l \| xargs sed -i -e "/\"/s/’/'/g;/\"/s/‘/'/g"
2017-07-30	replace "OS X" with "macOS"	davidak

2017-07-20	FD_SETSIZE check: BuildError -> Error	Eelco Dolstra
	BuildError denotes a permanent build failure, which is not the case here.
2017-07-18	Do not try to fill fd_set with fd>=FD_SETSIZE	Dmitry Kalinkin
	This is UB and causes buffer overflow and crash on linux.
2017-07-17	Always use base-16 for hashed mirror lookups	Eelco Dolstra
	In particular, don't use base-64, which we don't support. (We do have base-32 redirects for hysterical reasons.) Also, add a test for the hashed mirror feature.
2017-07-17	Make the hashes mirrors used by builtins.fetchurl configurable	Eelco Dolstra
	In particular, this allows it to be disabled in our tests.
2017-07-17	Fix accidental printError	Eelco Dolstra

2017-07-14	nix path-info: Show download sizes for binary cache stores	Eelco Dolstra
	E.g. $ nix path-info --json --store https://cache.nixos.org nixpkgs.thunderbird -S ... "downloadHash": "sha256:1jlixpzi225wwa0f4xdrwrqgi47ip1qpj9p06fyxxg07sfmyi4q0", "downloadSize": 43047620, "closureDownloadSize": 84745960 } ]
2017-07-14	nix path-info: Don't barf on invalid paths	Eelco Dolstra
	Now you get [ { "path": "/nix/store/fzvliz4j5xzvnd0w5zgw2l0ksqh578yk-bla", "valid": false } ]
2017-07-11	fetchTarball: Prevent concurrent downloads of the same file	Eelco Dolstra
	Fixes #849.
2017-07-07	Merge pull request #1445 from matthewbauer/macos-skip-hardlink	Eelco Dolstra
	Don’t hardlink disallowed paths in OS X.
2017-07-06	Don’t hardlink disallowed paths in OS X.	Matthew Bauer
	Fixes #1443
2017-07-04	Add X32 to the seccomp filter	Eelco Dolstra
	Fixes #1432.
2017-07-04	Sort substituters by priority	Eelco Dolstra
	Fixes #1438.
2017-07-04	getDefaultSubstituters(): Simplify initialisation	Eelco Dolstra
	As shlevy pointed out, static variables in C++11 have thread-safe initialisation.
2017-07-04	Add allow-new-privileges option	Eelco Dolstra
	This allows builds to call setuid binaries. This was previously possible until we started using seccomp. Turns out that seccomp by default disallows processes from acquiring new privileges. Generally, any use of setuid binaries (except those created by the builder itself) is by definition impure, but some people were relying on this ability for certain tests. Example: $ nix build '(with import <nixpkgs> {}; runCommand "foo" {} "/run/wrappers/bin/ping -c 1 8.8.8.8; exit 1")' --no-allow-new-privileges builder for ‘/nix/store/j0nd8kv85hd6r4kxgnwzvr0k65ykf6fv-foo.drv’ failed with exit code 1; last 2 log lines: cannot raise the capability into the Ambient set : Operation not permitted $ nix build '(with import <nixpkgs> {}; runCommand "foo" {} "/run/wrappers/bin/ping -c 1 8.8.8.8; exit 1")' --allow-new-privileges builder for ‘/nix/store/j0nd8kv85hd6r4kxgnwzvr0k65ykf6fv-foo.drv’ failed with exit code 1; last 6 log lines: PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data. 64 bytes from 8.8.8.8: icmp_seq=1 ttl=46 time=15.2 ms Fixes #1429.
2017-07-04	Support base-64 hashes	Eelco Dolstra
	Also simplify the Hash API. Fixes #1437.
2017-07-03	Replace a few bool flags with enums	Eelco Dolstra
	Functions like copyClosure() had 3 bool arguments, which creates a severe risk of mixing up arguments. Also, implement copyClosure() using copyPaths().
2017-06-20	Call SetDllDirectory("") after sqlite3 init on cygwin	David McFarland
	Cygwin sqlite3 is patched to call SetDllDirectory("/usr/bin") on init, which affects the current process and is inherited by child processes. It causes DLLs to be loaded from /usr/bin/ before $PATH, which breaks all sorts of things. A typical failures would be header/lib version mismatches (e.g. openssl when running checkPhase on openssh). We'll just set it back to the default value. Note that this is a problem with the cygwin version of sqlite3 (currently 3.18.0). nixpkgs doesn't have the problematic patch.
2017-06-19	Disable use of virtual hosting in aws-sdk-cpp	Eelco Dolstra
	Recently aws-sdk-cpp quietly switched to using S3 virtual host URIs (https://github.com/aws/aws-sdk-cpp/commit/69d9c53882), i.e. it sends requests to http://<bucket>.<region>.s3.amazonaws.com rather than http://<region>.s3.amazonaws.com/<bucket>. However this interacts badly with curl connection reuse. For example, if we do the following: 1) Check whether a bucket exists using GetBucketLocation. 2) If it doesn't, create it using CreateBucket. 3) Do operations on the bucket. then 3) will fail for a minute or so with a NoSuchBucket exception, presumably because the server being hit is a fallback for cases when buckets don't exist. Disabling the use of virtual hosts ensures that 3) succeeds immediately. (I don't know what S3's consistency guarantees are for bucket creation, but in practice buckets appear to be available immediately.)
