2017-03-03 Improve SSH handlingEelco Dolstra7-113/+185
* Unify SSH code in SSHStore and LegacySSHStore. * Fix a race starting the SSH master. We now wait synchronously for the SSH master to finish starting. This prevents the SSH clients from starting their own connections. * Don't use a master if max-connections == 1. * Add a "max-connections" store parameter. * Add a "compress" store parameter.

2017-03-01 TeeSink: Pre-reserve string spaceEelco Dolstra3-10/+21
When receiving a very large file, this can prevent the string from having tobe copied, which temporarily doubles memory consumption.
2017-03-01 RemoteStore::addToStore(): Send NAR rather than string containing NAREelco Dolstra5-37/+21
This allows the NAR to be streamed in the future (though we're not doing that yet).
2017-03-01 readString(): Read directly into std::stringEelco Dolstra1-3/+3
When reading a huge string, this halves memory consumption. (Strictly speaking, this appears only valid in C++17, but who cares...)
2017-03-01 Tweak messageEelco Dolstra1-1/+1
2017-03-01 nix-store --import: Fix importing unsigned pathsEelco Dolstra1-1/+1
2017-03-01 Fix assertion failure in nix-store --exportEelco Dolstra1-0/+3
Fixes #1173.
2017-03-01 Handle importing NARs containing files greater than 4 GiBEelco Dolstra7-81/+84
Also templatize readInt() to work for various integer types.
2017-02-28 Fix building against older curl versionsEelco Dolstra1-1/+4

2017-02-28 Improve SQLite busy handlingEelco Dolstra2-30/+42
2017-02-28 NarInfoDiskCache: Handle SQLite busy errorsEelco Dolstra1-104/+115
2017-02-28 In SQLite errors, include the database pathEelco Dolstra1-4/+8
This is necessary because we have multiple SQLite databases (e.g. the binary cache cache).
2017-02-28 Support auto-configuration of build-max-jobsEelco Dolstra2-2/+12
"build-max-jobs" and the "-j" option can now be set to "auto" to use the number of CPUs in the system. (Unlike build-cores, it doesn't use 0 to imply auto-configuration, because a) magic values are a bad idea in general; b) 0 is a legitimate value used to disable local building.) Fixes #1198.
2017-02-27 _SC_NPROCESSORS_ONLN -> std::thread::hardware_concurrency()Eelco Dolstra1-7/+3
2017-02-27 Retry downloads on HTTP/2 stream errorsEelco Dolstra1-1/+3
Issue #1254.
2017-02-24 nix-shell: Better error message when the shell can't be startedEelco Dolstra1-2/+4

2017-02-24 nix-shell: Overwrite environment variablesEelco Dolstra1-1/+1
Need to remember that std::map::insert() and emplace() don't overwrite existing entries... This fixes a regression relative to 1.11 that in particular triggers in nested nix-shells. Before: $ nativeBuildInputs=/foo nix-shell -p hello --run 'hello' build input /foo does not exist After: $ nativeBuildInputs=/foo nix-shell -p hello --run 'hello' Hello, world!
2017-02-22 RemoteStore::addToStore(): Pass content-addressability assertionEelco Dolstra6-3/+16
... and use this in Downloader::downloadCached(). This fixes $ nix-build https://nixos.org/channels/nixos-16.09-small/nixexprs.tar.xz -A hello error: cannot import path ‘/nix/store/csfbp1s60dkgmk9f8g0zk0mwb7hzgabd-nixexprs.tar.xz’ because it lacks a valid signature
2017-02-21 Handle CURLE_RECV_ERROR as a transient errorEelco Dolstra1-1/+1
This fixes unable to download ‘https://cache.nixos.org/nar/077h8ji74y9b0qx7rjk71xd80vjqp6q5gy137r553jlvdlxdcdlk.nar.xz’: HTTP error 200 (curl error: Failure when receiving data from the peer)
2017-02-21 Fix building without S3 supportEelco Dolstra2-2/+2
http://hydra.nixos.org/build/49031196/nixlog/2/raw
2017-02-21 Log AWS retriesEelco Dolstra1-0/+14
2017-02-16 Support netrc in <nix/fetchurl.nix>Eelco Dolstra5-7/+25
This allows <nix/fetchurl.nix> to fetch private Git/Mercurial repositories, e.g. import <nix/fetchurl.nix> { url = https://edolstra@bitbucket.org/edolstra/my-private-repo/get/80a14018daed.tar.bz2; sha256 = "1mgqzn7biqkq3hf2697b0jc4wabkqhmzq2srdymjfa6sb9zb6qs7"; } where /etc/nix/netrc contains: machine bitbucket.org login edolstra password blabla... This works even when sandboxing is enabled. To do: add unpacking support (i.e. fetchzip functionality).
2017-02-16 Move netrcFile to SettingsEelco Dolstra4-27/+23
Also get rid of Settings::processEnvironment(), it appears to be useless.
2017-02-16 Include "curl" in the User-Agent headerEelco Dolstra1-1/+1
Some sites (e.g. BitBucket) give a helpful 401 error when trying to download a private archive if the User-Agent contains "curl", but give a redirect to a login page otherwise (so for instance "nix-prefetch-url" will succeed but produce useless output).
2017-02-16 Merge pull request #1215 from k0001/netrc-1Eelco Dolstra1-0/+8
Add netrc-file support
2017-02-14 Add support for s3:// URIsEelco Dolstra5-63/+142
This adds support for s3:// URIs in all places where Nix allows URIs, e.g. in builtins.fetchurl, builtins.fetchTarball, <nix/fetchurl.nix> and NIX_PATH. It allows fetching resources from private S3 buckets, using credentials obtained from the standard places (i.e. AWS_* environment variables, ~/.aws/credentials and the EC2 metadata server). This may not be super-useful in general, but since we already depend on aws-sdk-cpp, it's a cheap feature to add.
2017-02-13 Merge pull request #1224 from dezgeg/confighEelco Dolstra14-24/+0
Unbreak 32-bit builds by always implicitly including config.h
2017-02-13 nix-daemon: Don't splice with len=SIZE_MAXTuomas Tynkkynen1-2/+3
Currently, 'nix-daemon --stdio' is always failing for me, due to the splice call always failing with (on a 32-bit host): splice(0, NULL, 3, NULL, 4294967295, SPLICE_F_MOVE) = -1 EINVAL (Invalid argument) With a bit of ftracing (and luck) the problem seems to be that splice() always fails with EINVAL if the len cast as ssize_t is negative: http://lxr.free-electrons.com/source/fs/read_write.c?v=4.4#L384 So use SSIZE_MAX instead of SIZE_MAX.

2017-02-08 Include config.h implicitly with '-include config.h' in CFLAGSTuomas Tynkkynen14-24/+0
Because config.h can #define things like _FILE_OFFSET_BITS=64 and not every compilation unit includes config.h, we currently compile half of Nix with _FILE_OFFSET_BITS=64 and other half with _FILE_OFFSET_BITS unset. This causes major havoc with the Settings class on e.g. 32-bit ARM, where different compilation units disagree with the struct layout.

2017-02-07 nix-copy-closure: Use computeFSClosure() and LegacySSHStoreEelco Dolstra1-12/+11
2017-02-07 Merge branch 'nix-copy-closure-c++' of https://github.com/shlevy/nixEelco Dolstra7-5/+94
2017-02-07 Add a LegacySSHStore that uses nix-store --serveEelco Dolstra2-0/+248
This is useful for nix-copy-closure.
2017-02-07 copyStorePath(): Don't require signatures for "trusted" storesEelco Dolstra2-0/+13
For example, SSH stores could be trusted.

2017-02-02 exportReferencesGraph: Only export in JSON format when in structured modeEelco Dolstra1-10/+16
This prevents breaking compatibility with builders that read "closure.*", since they would accidentally pick up the new JSON files.
2017-02-01 Restore default signal handling in child processesEelco Dolstra7-35/+33
In particular, this fixes Ctrl-C in nix-shell sessions.
