2012-10-03 When ‘--help’ is given, just run ‘man’ to show the manual pageEelco Dolstra25-329/+51
I.e. do what git does. I'm too lazy to keep the builtin help text up to date :-) Also add ‘--help’ to various commands that lacked it (e.g. nix-collect-garbage).
2012-10-03 Document ‘--repair’Eelco Dolstra3-6/+32
2012-10-03 nix-env: Support ‘--repair’ flagEelco Dolstra3-5/+9
2012-10-03 nix-build: Support ‘--repair’ flagEelco Dolstra1-1/+1
2012-10-03 Add a ‘--repair’ flag to nix-instantiateEelco Dolstra11-25/+36
This allows repairing corrupted derivations and other source files.
2012-10-03 Handle repairing paths that are in build-chroot-dirsEelco Dolstra1-0/+7
2012-10-03 When repairing a derivation, check and repair the entire output closureEelco Dolstra3-6/+91
If we find a corrupted path in the output closure, we rebuild the derivation that produced that particular path.
2012-10-02 Add a --repair flag to ‘nix-store -r’ to repair derivation outputsEelco Dolstra7-64/+116
With this flag, if any valid derivation output is missing or corrupt, it will be recreated by using a substitute if available, or by rebuilding the derivation. The latter may use hash rewriting if chroots are not available.
2012-10-02 nix-store -r: Get rid of an unnecessary call to buildPaths/ensurePathsEelco Dolstra1-4/+4
2012-10-02 nix-store --verify: Add an option ‘--repair’ to repair all ↵Eelco Dolstra4-11/+42
missing/corrupt paths Also, return a non-zero exit code if errors remain after verifying/repairing.
2012-10-02 Add operation ‘nix-store --repair-path’Eelco Dolstra8-36/+151
This operation allows fixing corrupted or accidentally deleted store paths by redownloading them using substituters, if available. Since the corrupted path cannot be replaced atomically, there is a very small time window (one system call) during which neither the old (corrupted) nor the new (repaired) contents are available. So repairing should be used with some care on critical packages like Glibc.
2012-09-28 Handle octal escapes in /proc/self/mountinfoEelco Dolstra3-2/+24
2012-09-28 Print a more descriptive error message if setting up the build environment failsEelco Dolstra1-3/+14
2012-09-27 Allow dashes in identifiersEelco Dolstra4-4/+9
In Nixpkgs, the attribute in all-packages.nix corresponding to a package is usually equal to the package name. However, this doesn't work if the package contains a dash, which is fairly common. The convention is to replace the dash with an underscore (e.g. "dbus-lib" becomes "dbus_glib"), but that's annoying. So now dashes are valid in variable / attribute names, allowing you to write: dbus-glib = callPackage ../development/libraries/dbus-glib { }; and buildInputs = [ dbus-glib ]; Since we don't have a negation or subtraction operation in Nix, this is unambiguous.
2012-09-25 Add "on Linux" qualifierEelco Dolstra1-2/+2
2012-09-25 Make the store writable before creating /nix/store/.linksEelco Dolstra1-2/+1
2012-09-25 Document that Nix requires GNU MakeEelco Dolstra1-1/+4
Fixes #44.
2012-09-25 Update release notesEelco Dolstra1-0/+29
2012-09-25 Merge branch 'readonly-store'Eelco Dolstra14-135/+106
2012-09-25 Include <sys/types.h> for off_tEelco Dolstra1-0/+1
Reported by "gio" on IRC.
2012-09-21 Style fixEelco Dolstra2-6/+6
2012-09-19 Support xz compression in the download-using-manifests substituterEelco Dolstra3-8/+21
2012-09-19 Remove setting of the immutable bitEelco Dolstra5-96/+35
Using the immutable bit is problematic, especially in conjunction with store optimisation. For instance, if the garbage collector deletes a file, it has to clear its immutable bit, but if the file has additional hard links, we can't set the bit afterwards because we don't know the remaining paths. So now that we support having the entire Nix store as a read-only mount, we may as well drop the immutable bit. Unfortunately, we have to keep the code to clear the immutable bit for backwards compatibility.
2012-09-19 Support having /nix/store as a read-only bind mountEelco Dolstra2-0/+41
It turns out that the immutable bit doesn't work all that well. A better way is to make the entire Nix store a read-only bind mount, i.e. by doing $ mount --bind /nix/store /nix/store $ mount -o remount,ro,bind /nix/store (This would typically done in an early boot script, before anything from /nix/store is used.) Since Nix needs to be able to write to the Nix store, it now detects if /nix/store is a read-only bind mount and then makes it writable in a private mount namespace.
2012-09-19 Templatise tokenizeString()Eelco Dolstra10-39/+30
2012-09-18 Keep build directory if not all expected outputs were producedEelco Dolstra1-3/+3
Fixes issue #123 in Nixpkgs.
2012-09-14 Test whether GNU tar understands --warning=no-timestampEelco Dolstra1-2/+2

2012-09-13 nix-collect-garbage: Support --dry-runEelco Dolstra2-3/+7
2012-09-13 nix-env --delete-generations: Support --dry-run flagEelco Dolstra2-6/+12
Fixes #43.
2012-09-13 Add a test for nix-profile.shEelco Dolstra3-1/+12
2012-09-13 nix-profile.sh: Revert to single-user versionEelco Dolstra1-44/+11
Commit 6a214f3e06fa1c5f0a4d40e555f14d87691af297 copied most of the Nix shell initialisation code from NixOS to nix-profile.sh; however, that code assumes a multi-user install and is Linux-specific (e.g. it calls the "stat" command). So go back to the simple single-user version. Fixes #49.
2012-09-13 Remove double Fedora release suffixEelco Dolstra1-1/+1
2012-09-13 Put a time-to-live on negative binary cache lookupsEelco Dolstra1-3/+30
Negative lookups are purged from the DB after a day, at most once per day. However, for non-"have" lookups (e.g. all except "nix-env -qas"), negative lookups are ignored after one hour. This is to ensure that you don't have to wait a day for an operation like "nix-env -i" to start using new binaries in the cache. Should probably make this configurable.
2012-09-13 DohEelco Dolstra1-2/+2
2012-09-13 RemoteStore::connectToDaemon(): Set close-on-exec flagEelco Dolstra1-0/+1
This ensures that "nix-build --run-env" doesn't keep a connection to the worker open, preventing it from exiting.
2012-09-13 Vacuum the SQLite DB after running the garbage collectorEelco Dolstra3-0/+12
2012-09-13 Delete paths in a component in topologically sorted orderEelco Dolstra1-1/+3
The outputs of a derivation can refer to each other (even though they cannot have cycles), so they have to be deleted in the right order. http://hydra.nixos.org/build/3026118
2012-09-13 Fix the store optimisation testEelco Dolstra1-2/+2

2012-09-13 nix-channel: Add option to force fetching of manifestsEelco Dolstra2-0/+19
2012-09-13 Delete manifests in "nix-channel --remove" or when a binary cache is availableEelco Dolstra4-35/+47
2012-09-13 Disable auto store optimisation for nowEelco Dolstra1-1/+1
I've seen operations like "nix-store --import" take much longer on one system. So default to off until I've investigated this a bit further.
2012-09-13 In startBuilder(), only print the new paths we're buildingEelco Dolstra1-2/+3
2012-09-12 Handle gc-keep-outputs and gc-keep-derivations both enabledEelco Dolstra2-95/+100
If the options gc-keep-outputs and gc-keep-derivations are both enabled, you can get a cycle in the liveness graph. There was a hack to handle this, but it didn't work with multiple-output derivations, causing the garbage collector to fail with errors like ‘error: cannot delete path `...' because it is in use by `...'’. The garbage collector now handles strongly connected components in the liveness graph as a unit and decides whether to delete all or none of the paths in an SCC.
2012-09-12 Build hook: Pass the timeout to the remote builderEelco Dolstra2-4/+5
Note that this will only work if the client has a very recent Nix version (post 15e1b2c223494ecb5efefc3ea0e3b926a6b1d7dc), otherwise the --option flag will just be ignored. Fixes #50.
2012-09-12 Fix test failure on DarwinEelco Dolstra2-1/+2
Apparently our DBD::SQLite links against /usr/lib/libsqlite3.dylib, which is an old version that doesn't respect foreign key constraints. So manifests/cache.sqlite doesn't get updated properly when a manifest disappears. We should fix our DBD::SQLite, but in the meantime this will fix the test. http://hydra.nixos.org/build/3017959
2012-09-12 Compatibility fix for WWW::Curl < 4.14Eelco Dolstra1-1/+2
Older versions of WWW::Curl don't support scalar references for CURLOPT_WRITEDATA directly. http://hydra.nixos.org/build/3017188
2012-09-11 Don't put results symlinks in the tests directoryEelco Dolstra12-24/+25
2012-09-11 Test hash rewritingEelco Dolstra1-4/+20
2012-09-11 Fix "non-zero padding" errorEelco Dolstra1-1/+2
Probably it's not a good idea to pass a temporary object to StringSource.
