2013-11-25 Add a Makefile for the Perl stuffEelco Dolstra1-1/+1
2013-10-24 Fix segfault on DarwinEelco Dolstra1-0/+1
Ever since SQLite in Nixpkgs was updated to 3.8.0.2, Nix has randomly segfaulted on Darwin: http://hydra.nixos.org/build/6175515 http://hydra.nixos.org/build/6611038 It turns out that this is because the binary cache substituter somehow ends up loading two versions of SQLite: the one in Nixpkgs and the other from /usr/lib/libsqlite3.dylib. It's not exactly clear why the latter is loaded, but it appears to be because WWW::Curl indirectly loads /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation, which in turn seems to load /usr/lib/libsqlite3.dylib. This leads to a segfault when Perl exits: #0 0x00000001010375f4 in sqlite3_finalize () #1 0x000000010125806e in sqlite_st_destroy () #2 0x000000010124bc30 in XS_DBD__SQLite__st_DESTROY () #3 0x00000001001c8155 in XS_DBI_dispatch () ... #14 0x0000000100023224 in perl_destruct () #15 0x0000000100000d6a in main () ... The workaround is to explicitly load DBD::SQLite before WWW::Curl.
2013-09-06 Don't apply the CPU affinity hack to nix-shell (and other Perl programs)Eelco Dolstra1-0/+1
As discovered by Todd Veldhuizen, the shell started by nix-shell has its affinity set to a single CPU. This is because nix-shell connects to the Nix daemon, which causes the affinity hack to be applied. So we turn this off for Perl programs.
2013-06-20 Don't keep "disabled" substituters runningEelco Dolstra1-1/+4
For instance, it's pointless to keep copy-from-other-stores running if there are no other stores, or download-using-manifests if there are no manifests. This also speeds things up because we don't send queries to those substituters.
2013-05-10 build-remote.pl: Properly close the SSH connection between attemptsEelco Dolstra1-0/+1
2013-05-03 Fixing the pv position regarding compressionLluís Batlle i Rossell1-1/+1
Problem noticed by niksnut.
2013-05-03 Adding ETA support to the --show-progress in nix-copy-closureLluís Batlle i Rossell1-4/+8
Based on https://github.com/NixOS/nix/pull/6 from shlevy
2013-03-08 Revert "Prevent config.h from being clobbered"Eelco Dolstra1-9/+12
This reverts commit 28bba8c44f484eae38e8a15dcec73cfa999156f6.
2013-03-08 Fix annoying Perl 5.16 warningsEelco Dolstra1-17/+17
I.e. Subroutine Nix::Store::isValidPath redefined at /nix/store/clfzsf6gi7qh5i9c0vks1ifjam47rijn-perl-5.16.2/lib/perl5/5.16.2/XSLoader.pm line 92. and so on.

2012-12-20 Give a better error message if writeFile fails due to permission issuesEelco Dolstra1-2/+2
2012-11-23 nix-copy-closure: Add flag ‘--use-substitutes’Eelco Dolstra1-1/+8
2012-10-17 nix-push: Only generate and copy a NAR if it doesn't already existEelco Dolstra2-1/+58
This prevents unnecessary and slow rebuilds of NARs that already exist in the binary cache.
2012-09-19 Support xz compression in the download-using-manifests substituterEelco Dolstra1-6/+12
2012-09-13 Delete manifests in "nix-channel --remove" or when a binary cache is availableEelco Dolstra1-21/+39

2012-08-27 Add missing fileEelco Dolstra1-0/+8
2012-07-30 Refactor settings processingEelco Dolstra1-1/+1
Put all Nix configuration flags in a Settings object.
2012-07-30 Pass configuration settings to the substitutersEelco Dolstra1-1/+9
Previously substituters could read nix.conf themselves, but this didn't take --option flags into account.
2012-07-18 Merge branch 'master' into no-manifestsEelco Dolstra2-0/+12
2012-07-17 Add function queryPathFromHashPart()Eelco Dolstra2-0/+12
To implement binary caches efficiently, Hydra needs to be able to map the hash part of a store path (e.g. "gbg...zr7") to the full store path (e.g. "/nix/store/gbg...kzr7-subversion-1.7.5"). (The binary cache mechanism uses hash parts as a key for looking up store paths to ensure privacy.) However, doing a search in the Nix store for /nix/store/<hash>* is expensive since it requires reading the entire directory. queryPathFromHashPart() prevents this by doing a cheap database lookup.
2012-07-17 queryPathInfo(): return hash in base-32 if desiredEelco Dolstra1-2/+2
Cherry-picked from the no-manifests branch.
2012-07-11 Set the User-Agent header to "Nix/<version>"Eelco Dolstra1-0/+2
2012-07-09 download-from-binary-cache: add nix.conf optionsEelco Dolstra1-3/+3
2012-07-02 nix-push: Always generate base-32 hashesEelco Dolstra1-2/+2
2012-06-29 First attempt at the manifest-less substituterEelco Dolstra1-0/+1
2012-06-29 Use XZ compression in binary cachesEelco Dolstra1-1/+2
XZ compresses significantly better than bzip2. Here are the compression ratios and execution times (using 4 cores in parallel) on my /var/run/current-system (3.1 GiB): bzip2: total compressed size 849.56 MiB, 30.8% [2m08] xz -6: total compressed size 641.84 MiB, 23.4% [6m53] xz -7: total compressed size 621.82 MiB, 22.6% [7m19] xz -8: total compressed size 599.33 MiB, 21.8% [7m18] xz -9: total compressed size 588.18 MiB, 21.4% [7m40] Note that compression takes much longer. More importantly, however, decompression is much faster: bzip2: 1m47.274s xz -6: 0m55.446s xz -7: 0m54.119s xz -8: 0m52.388s xz -9: 0m51.842s The only downside to using -9 is that decompression takes a fair amount (~65 MB) of memory.
2012-05-10 Support building with the Perl XS bindings disabledEelco Dolstra2-2/+67
Since the Perl bindings require shared libraries, this is required on platforms such as Cygwin where we do a static build.
2012-04-13 nix-copy-closure: Move the progressViewer directly adjacent to the ssh call ↵Shea Levy1-1/+1
so that network progress is what's measured
2012-04-13 Add the '--show-progress' flag to nix-copy-closureShea Levy1-3/+4
2012-04-10 Unconfuse RobEelco Dolstra1-2/+2
2012-03-19 Add a command "nix-build --run-env" to reproduce the environment of a derivationEelco Dolstra2-0/+43
This command builds or fetches all dependencies of the given derivation, then starts a shell with the environment variables from the derivation. This shell also sources $stdenv/setup to initialise the environment further. The current directory is not changed. Thus this is a convenient way to reproduce a build environment in an existing working tree. Existing environment variables are left untouched (unless the derivation overrides them). As a special hack, the original value of $PATH is appended to the $PATH produced by $stdenv/setup. Example session: $ nix-build --run-env '<nixpkgs>' -A xterm (the dependencies of xterm are built/fetched...) $ tar xf $src $ ./configure $ make $ emacs (... hack source ...) $ make $ ./xterm
2012-03-05 nix-copy-closure: don't print copied path on stdoutEelco Dolstra1-1/+1
We're already printing progress on stderr, so printing them on stdout afterwards is kind of useless.
2012-03-05 Restore progress indication during nix-copy-closureEelco Dolstra1-1/+0
2012-01-03 * Sync with the trunk.Eelco Dolstra1-0/+1
2012-01-03 * Ignore missing manifest symlinks.Eelco Dolstra1-0/+1
2012-01-03 * Add a test for nix-channel.Eelco Dolstra1-0/+1
* Refactor the nix-channel unpacker a bit.
2011-12-02 * Add some more functions to the Perl bindings.Eelco Dolstra2-1/+48
2011-11-29 * Don't require a specific Perl version.Eelco Dolstra1-1/+0
2011-11-29 * download-using-manifests: use the Perl bindings.Eelco Dolstra2-1/+16
2011-11-29 * For consistency with "nix-store -q --hash", produce hashes inEelco Dolstra1-1/+1
base-32. (This affects Hydra manifests.)
2011-11-23 * Add an API function exportPaths() that provides the functionality ofEelco Dolstra3-1/+60
‘nix-store --export’. * Add a Perl module that provides the functionality of ‘nix-copy-closure --to’. This is used by build-remote.pl so it no longer needs to start a separate nix-copy-closure process. Also, it uses the Perl API to do the export, so it doesn't need to start a separate nix-store process either. As a result, nix-copy-closure and build-remote.pl should no longer fail on very large closures due to an "Argument list too long" error. (Note that having very many dependencies in a single derivation can still fail because the environment can become too large. Can't be helped though.)
2011-11-23 * build-remote.pl: drop a hard-coded reference to /nix/etc/nix.Eelco Dolstra1-0/+1
2011-11-22 * Move initialisation of variables like nixConfDir from libmain toEelco Dolstra1-3/+1
libstore so that the Perl bindings can use it as well. It's vital that the Perl bindings use the configuration file, because otherwise nix-copy-closure will fail with a ‘database locked’ message if the value of ‘use-sqlite-wal’ is changed from the default.
2011-11-16 * nix-pull: update the Nix manifest cache if necessary. Also, don'tEelco Dolstra1-4/+4
read the manifest just to check the version and print the number of paths. This makes nix-pull very fast for the cached cache (speeding up nixos-rebuild without the ‘--no-pull’ or ‘--fast’ options).
2011-11-16 * Don't decompress the manifests in /nix/var/nix/manifest. This savesEelco Dolstra1-2/+8
disk space, and, since they're typically only decompressed once (to fill the manifest cache), doesn't make things slower.
2011-11-16 * Remove obsolete line.Eelco Dolstra1-1/+0
2011-11-16 * Re-use prepared statements across insertions into the manifest cacheEelco Dolstra1-8/+12
DB. This speeds up creating the cache from 16.1s to 7.9s on my system.
