2008-12-12 * Put chroots in the Nix store. This ensures that we can create hardEelco Dolstra2-2/+14
links to the inputs.
2008-12-12 * Simplify deleting .lock files in /nix/store: just don't delete themEelco Dolstra1-30/+18
if they belong a path that's currently being built. This gets rid of some Cygwin-specific code.
2008-12-12 * Detect whether unshare() is available.Eelco Dolstra1-4/+1
2008-12-12 * Use a PathSet for the chroot directories so that we don'tEelco Dolstra1-6/+7
accidentally bind-mount a directory twice.
2008-12-12 * Define _GNU_SOURCE. Hopefully this fixes the build on Debian 4.0Eelco Dolstra1-0/+3
(http://hydra.nixos.org/nixlog/384/1).
2008-12-11 * Don't provide the whole Nix store in the chroot, but only theEelco Dolstra1-10/+44
closure of the inputs. This really enforces that there can't be any undeclared dependencies on paths in the store. This is done by creating a fake Nix store and creating bind-mounts or hard-links in the fake store for all paths in the closure. After the build, the build output is moved from the fake store to the real store. TODO: the chroot has to be on the same filesystem as the Nix store for this to work, but this isn't enforced yet. (I.e. it only works currently if /tmp is on the same FS as /nix/store.)
2008-12-11 * Revert r13150: now that we use private namespaces for the chroot, weEelco Dolstra3-8/+1
don't have to put the chroot in /nix/var/nix/chroots anymore. They're back in /tmp now.
2008-12-11 * Provide a minimal /etc/passwd in the chroot to keep some buildersEelco Dolstra1-1/+12
happy.
2008-12-11 * Do chroot builds in a private namespace. This means that all theEelco Dolstra1-134/+45
bind-mounts we do are only visible to the builder process and its children. So accidentally doing "rm -rf" on the chroot directory won't wipe out /nix/store and other bind-mounted directories anymore. Also, the bind-mounts in the private namespace disappear automatically when the builder exits.
2008-12-11 * Open the connection to the daemon lazily (on demand) so thatEelco Dolstra2-4/+36
read-only operations (like nix-env -qa) work properly when the daemon isn't running.
2008-12-04 * Build on Debian 4.0 (GCC 4.1.1).Eelco Dolstra1-1/+1
2008-12-04 * Propagate --max-silent-time to remote machines.Eelco Dolstra1-0/+1
2008-12-04 * When using build hooks, for any nix-store -r build operation, it isEelco Dolstra1-1/+12
necessary that at least one build hook doesn't return "postpone", otherwise nix-store will barf ("waiting for a build slot, yet there are no running children"). So inform the build hook when this is the case, so that it can start a build even when that would exceed the maximum load on a machine.
2008-12-03 * addToStore() in nix-worker: don't write the NAR dump received fromEelco Dolstra2-19/+33
the client to a temporary directory, as that is highly inefficient.
2008-12-03 * Pass HashType values instead of strings.Eelco Dolstra6-16/+17
2008-12-03 * Made addToStore() a lot more efficient: it no longer reads the pathEelco Dolstra1-32/+28
being copied 3 times in the worst case. It doesn't run in constant space, but it didn't do that anyway.
2008-12-03 * Unify the treatment of sources copied to the store, and recursiveEelco Dolstra6-47/+108
SHA-256 outputs of fixed-output derivations. I.e. they now produce the same store path: $ nix-store --add x /nix/store/j2fq9qxvvxgqymvpszhs773ncci45xsj-x $ nix-store --add-fixed --recursive sha256 x /nix/store/j2fq9qxvvxgqymvpszhs773ncci45xsj-x the latter being the same as the path that a derivation derivation { name = "x"; outputHashAlgo = "sha256"; outputHashMode = "recursive"; outputHash = "..."; ... }; produces. This does change the output path for such fixed-output derivations. Fortunately they are quite rare. The most common use is fetchsvn calls with SHA-256 hashes. (There are a handful of those is Nixpkgs, mostly unstable development packages.) * Documented the computation of store paths (in store-api.cc).
2008-11-20 * Nix daemon: reload the configuration file after forking (NIX-100).Eelco Dolstra2-0/+9
2008-11-19 * Files in the info directory starting with "." are temporary filesEelco Dolstra1-2/+5
and don't indicate path validity.
2008-11-14 * Restore SIGPIPE to SIG_DFL when running the builder. This preventsEelco Dolstra1-0/+13
subtle and often hard-to-reproduce bugs where programs in pipes either barf with a "Broken pipe" message or not, depending on the exact timing conditions. This particularly happened in GNU M4 (and Bison, which uses M4).
2008-11-12 * Some somewhat ad hoc mechanism to allow the build farm to monitorEelco Dolstra4-6/+65
build progress.
2008-11-11 * Pass the --no-build-output flag to the daemon.Eelco Dolstra2-1/+3
2008-11-11 * Add /dev/pts to the default nix.conf.Eelco Dolstra1-5/+4
2008-10-29 * Put the chroots under /nix/var/nix/chroots to reduce the risk ofEelco Dolstra3-10/+14
disasters involving `rm -rf' on bind mounts. Will try the definitive fix (per-process mounts, apparently possible via the CLONE_NEWNS flag in clone()) some other time.
2008-10-16 libstore: Always mount `/dev/pts' individually.Ludovic Courtès1-0/+5
This fixes problems such as Tcl's PTY handling: ERROR: The system has no more ptys. Ask your system administrator to create more.
2008-10-16 * Bug fix for building on some old installations (contributed by Pjotr).Eelco Dolstra1-0/+6
2008-09-17 * GC option `--max-atime' that specifies an upper limit to the lastEelco Dolstra3-6/+17
accessed time of paths that may be deleted. Anything more recently used won't be deleted. The time is specified in time_t, e.g. seconds since 1970-01-01 00:00:00 UTC; use `date +%s' to convert to time_t from the command line. Example: to delete everything that hasn't been used in the last two months: $ nix-store --gc -v --max-atime $(date +%s -d "2 months ago")
2008-09-17 * Typo.Eelco Dolstra1-1/+1
2008-09-17 * Some refactoring. Better output with `-v' for --use-atime.Eelco Dolstra2-35/+40
2008-09-17 * Garbage collector: added an option `--use-atime' to delete paths inEelco Dolstra4-39/+189
order of ascending last access time. This is useful in conjunction with --max-freed or --max-links to prefer deleting non-recently used garbage, which is good (especially in the build farm) since garbage may become live again. The code could easily be modified to accept other criteria for ordering garbage by changing the comparison operator used by the priority queue in collectGarbage().
2008-08-27 * Explicitly set PWD to prevent problems with chroot builds. InEelco Dolstra1-0/+6
particular, dietlibc cannot figure out the cwd because the inode of the current directory doesn't appear in .. (because getdents returns the inode of the mount point).
2008-08-27 * Create a /tmp with 1777 permission in the chroot. Some buildersEelco Dolstra1-12/+32
need a writable /tmp (they don't respect $TMPDIR).
2008-08-25 * Disable chroot builds for fixed-output derivations so that we don'tEelco Dolstra1-1/+8
need /etc in the chroot (in particular, /etc/resolv.conf for fetchurl). Not having /etc/resolv.conf in the chroot is a good thing, since we don't want normal derivations to download files.
2008-08-25 * Strip off the `.nix' suffix from the attribute name for files inEelco Dolstra1-3/+2
~/.nix-defexpr, otherwise the attribute cannot be selected with the `-A' option. Useful if you want to stick a Nix expression directly in ~/.nix-defexpr.
2008-08-14 * Backward compatibility check to prevent nixos-rebuild from barfingEelco Dolstra2-1/+2
when upgrading Nix.
2008-08-14 * Increase the sleep periods a bit to make the test less likely toEelco Dolstra1-4/+0
fail on slow machines. Of course it would be better if this test wasn't timing dependent...
2008-08-05 * Better error checking of the data from the substituters.Eelco Dolstra1-21/+16
2008-08-04 * build.cc: only use a substituter if it returns info for a path.Eelco Dolstra3-51/+57
2008-08-04 * nix-env --dry-run: show the total size of the substituterEelco Dolstra3-3/+11
downloads.
2008-08-04 * querySubstitutablePathInfo: work properly when run via the daemon.Eelco Dolstra4-8/+20
* --dry-run: print the paths that we don't know how to build/substitute.
2008-08-02 * Make nix-env --dry-run print the paths to be substituted correctlyEelco Dolstra8-178/+187
again. (After the previous substituter mechanism refactoring I didn't update the code that obtains the references of substitutable paths.) This required some refactoring: the substituter programs are now kept running and receive/respond to info requests via stdin/stdout.
2008-07-18 * Allow read-only access to the store (e.g., non-root users on NixOSEelco Dolstra1-5/+9
can do operations like "nix-store -qR <path>" even without the Nix daemon).
2008-06-18 (no commit message)Eelco Dolstra1-1/+1
2008-06-18 * Garbage collector: option `--max-freed' to stop after at least NEelco Dolstra3-10/+36
bytes have been freed, `--max-links' to stop when the Nix store directory has fewer than N hard links (the latter being important for very large Nix stores on filesystems with a 32000 subdirectories limit).
2008-06-18 * `nix-store --optimise': handle files with >= 32000 hard links.Eelco Dolstra1-6/+31
(There can easily be more than 32000 occurrences of the empty file.)
2008-06-18 * Some refactoring: put the GC options / results in separate structs.Eelco Dolstra9-111/+149
* The garbage collector now also prints the number of blocks freed.
2008-06-14 * Note.Eelco Dolstra1-1/+5
2008-06-13 * Garbage collector: don't do a complete topological sort of the NixEelco Dolstra2-74/+87
store under the reference relation, since that means that the garbage collector will need a long time to start deleting paths. Instead just delete the referrers of a path first.
2008-06-13 * Print some progress info during the early GC stages.Eelco Dolstra2-1/+9
2008-06-09 * Merged the no-bdb branch (-r10900:HEADEelco Dolstra11-674/+766
https://svn.nixos.org/repos/nix/nix/branches/no-bdb).
