| 2012-03-01 | Remove dependency on sqlite3_table_column_metadata | Eelco Dolstra | 1 | -7/+0 | |
| Not all SQLite builds have the function sqlite3_table_column_metadata. We were only using it in a schema upgrade check for compatibility with databases that were probably never seen in the wild. So remove it. | |||||
| 2012-03-01 | Fix an uninitialised variable | Eelco Dolstra | 1 | -0/+1 | |
| The variable ‘useChroot’ was not initialised properly. This caused random failures if using the build hook. Seen on Mac OS X 10.7 with Clang. Thanks to KolibriFX for finding this :-) | |||||
| 2012-02-18 | Fix chroots builds | Eelco Dolstra | 1 | -0/+16 | |
| Chroots are initialised by hard-linking inputs from the Nix store to the chroot. This doesn't work if the input has its immutable bit set, because it's forbidden to create hard links to immutable files. So temporarily clear the immutable bit when creating and destroying the chroot. Note that making regular files in the Nix store immutable isn't very reliable, since the bit can easily become cleared: for instance, if we run the garbage collector after running ‘nix-store --optimise’. So maybe we should only make directories immutable. | |||||
| 2012-02-15 | On Linux, make the Nix store really read-only by using the immutable bit | Eelco Dolstra | 6 | -4/+122 | |
| I was bitten one time too many by Python modifying the Nix store by creating *.pyc files when run as root. On Linux, we can prevent this by setting the immutable bit on files and directories (as in ‘chattr +i’). This isn't supported by all filesystems, so it's not an error if setting the bit fails. The immutable bit is cleared by the garbage collector before deleting a path. The only tricky aspect is in optimiseStore(), since it's forbidden to create hard links to an immutable file. Thus optimiseStore() temporarily clears the immutable bit before creating the link. | |||||
| 2012-02-15 | Fix a broken guard around utime() | Eelco Dolstra | 1 | -2/+5 | |
| Because of an outdated check for a timestamp of 0, we were calling utime() even when it wasn't necessary. | |||||
| 2012-02-15 | Don't use deletePath() to delete a single file | Eelco Dolstra | 1 | -1/+1 | |
| 2012-02-09 | Fix error message | Eelco Dolstra | 1 | -3/+4 | |
| This fixes the error message error: file `' was not found in the Nix search path (add it using $NIX_PATH or -I) | |||||
| 2012-02-09 | Use data() instead of c_str() where appropriate | Eelco Dolstra | 9 | -18/+18 | |
| 2012-02-04 | * Inline some functions and get rid of the indirection through | Eelco Dolstra | 7 | -116/+94 | |
| EvalState::eval(). This gives a 12% speedup on ‘nix-instantiate /etc/nixos/nixos/ -A system --readonly-mode’ (from 1.01s to 0.89s). | |||||
| 2012-02-04 | * Print elapsed evaluation time. | Eelco Dolstra | 1 | -1/+9 | |
| 2012-01-26 | * Fix importing a derivation. This gave a segfault. | Eelco Dolstra | 1 | -8/+23 | |
| 2012-01-19 | * Allow comparisons between derivations by comparing the outPath | Eelco Dolstra | 1 | -2/+14 | |
| attributes. | |||||
| 2012-01-19 | * Add some debug output to print the derivation name once it's known. | Eelco Dolstra | 1 | -1/+4 | |
| This makes it easier to pinpoint the source of a crash. | |||||
| 2012-01-17 | * Added a command ‘nix-store --print-env $drvpath’ that prints out the | Eelco Dolstra | 1 | -0/+35 | |
| environment of the given derivation in a format that can be sourced by the shell, e.g. $ eval "$(nix-store --print-env $(nix-instantiate /etc/nixos/nixpkgs -A pkg))" $ NIX_BUILD_TOP=/tmp $ source $stdenv/setup This is especially useful to reproduce the environment used to build a package outside of its builder for development purposes. TODO: add a nix-build option to do the above and fetch the dependencies of the derivation as well. | |||||
| 2012-01-07 | * Don't create thunks for simple constants (integers, strings, paths) | Eelco Dolstra | 5 | -133/+193 | |
| and allocate them only once. * Move Value and related functions into value.hh. | |||||
| 2012-01-04 | * Remove dead code. | Eelco Dolstra | 2 | -4/+0 | |
| 2012-01-04 | * Don't use dynamic_cast, it's very slow. "nix-instantiate | Eelco Dolstra | 3 | -24/+23 | |
| /etc/nixos/nixos -A system" spent about 10% of its time in dynamic_cast. | |||||
| 2012-01-03 | * Drop the inefficient "Path" suffix in output attribute names. | Eelco Dolstra | 1 | -3/+1 | |
| 2012-01-03 | * Move the implementation of the ‘derivation’ primop into a separate | Eelco Dolstra | 2 | -25/+3 | |
| file. | |||||
| 2012-01-03 | * Sync with the trunk. | Eelco Dolstra | 1 | -1/+1 | |
| 2012-01-03 | * Refactoring: Get rid of a few subdirectories in corepkgs/, and some | Eelco Dolstra | 1 | -1/+1 | |
| other simplifications. * Use <nix/...> to locate the corepkgs. This allows them to be overriden through $NIX_PATH. * Use bash's pipefail option in the NAR builder so that we don't need to create a temporary file. | |||||
| 2011-12-30 | * Support multiple outputs in nix-store (specifically the ‘--query’ | Eelco Dolstra | 1 | -43/+63 | |
| and ‘--realise’ actions). | |||||
| 2011-12-30 | * Oops. | Eelco Dolstra | 1 | -1/+1 | |
| 2011-12-30 | * Move topoSortPaths() out of gc.cc. | Eelco Dolstra | 2 | -36/+36 | |
| 2011-12-30 | * Reject a build if there is a cycle among the outputs. This is | Eelco Dolstra | 4 | -9/+24 | |
| necessary because existing code assumes that the references graph is acyclic. | |||||
| 2011-12-30 | * Sync with the trunk. | Eelco Dolstra | 5 | -21/+54 | |
| 2011-12-25 | * Make sure that lock files are cleaned up properly when building | Eelco Dolstra | 1 | -7/+7 | |
| through the build hook. | |||||
| 2011-12-22 | * Oops. | Eelco Dolstra | 1 | -1/+1 | |
| 2011-12-22 | * In the garbage collector, delete invalid paths before deleting | Eelco Dolstra | 3 | -12/+45 | |
| unreachable paths. This matters when using --max-freed etc.: unreachable paths could become reachable again, so it's nicer to keep them if there is "real" garbage to be deleted. Also, don't use readDirectory() but read the Nix store and delete invalid paths in parallel. This reduces GC latency on very large Nix stores. | |||||
| 2011-12-22 | * Drop unnecessary call to canonPath() (nixStore is already canonical). | Eelco Dolstra | 1 | -1/+1 | |
| 2011-12-21 | * Another case of lock file permissions being too liberal. | Eelco Dolstra | 1 | -1/+1 | |
| 2011-12-21 | * The ‘foo.drvPath’ feature was already broken in read-only mode. | Eelco Dolstra | 1 | -1/+2 | |
| Since it's rarely used and fixing it is too much work right now, just document it. | |||||
| 2011-12-21 | Revert previous commit | Shea Levy | 1 | -9/+0 | |

| 2011-12-21 | Detect and reject mutually-referential outputs | Shea Levy | 1 | -0/+9 | |
| There is probably a more efficient way to do this. | |||||
| 2011-12-21 | * Simplify the context handling logic. | Eelco Dolstra | 1 | -24/+13 | |
| 2011-12-20 | * Fix the build. | Eelco Dolstra | 2 | -2/+2 | |
| 2011-12-16 | * Sync with the trunk. | Eelco Dolstra | 26 | -275/+461 | |
| 2011-12-16 | * importPath() -> importPaths(). Because of buffering of the input | Eelco Dolstra | 10 | -57/+75 | |
| stream it's now necessary for the daemon to process the entire sequence of exported paths, rather than letting the client do it. | |||||
| 2011-12-16 | * Avoid expensive conversions from char arrays to STL strings. | Eelco Dolstra | 3 | -13/+25 | |
| 2011-12-16 | * Make the import operation through the daemon much more efficient | Eelco Dolstra | 6 | -44/+68 | |
| (way fewer roundtrips) by allowing the client to send data in bigger chunks. * Some refactoring. | |||||
| 2011-12-16 | * Clean up exception handling. | Eelco Dolstra | 2 | -3/+10 | |
| 2011-12-15 | * Refactoring: move sink/source buffering into separate classes. | Eelco Dolstra | 8 | -90/+125 | |
| * Buffer the HashSink. This speeds up hashing a bit because it prevents lots of calls to the hash update functions (e.g. nix-hash went from 9.3s to 8.7s of user time on the closure of my /var/run/current-system). | |||||
| 2011-12-15 | * Buffer reads in FdSource. Together with write buffering, this | Eelco Dolstra | 2 | -10/+32 | |
| significantly cuts down the number of syscalls (e.g., for "nix-store -qR /var/run/current-system" via the daemon, it reduced the number of syscalls in the client from 29134 to 4766 and in the daemon from 44266 to 20666). | |||||
| 2011-12-14 | * Buffer writes in FdSink. This significantly reduces the number of | Eelco Dolstra | 4 | -14/+50 | |
| system calls / context switches when dumping a NAR and in the worker protocol. | |||||
| 2011-12-14 | * Remove the terminate handler, which was only really needed because | Eelco Dolstra | 1 | -23/+0 | |
| of Berkeley DB (see r8632). | |||||
| 2011-12-05 | * Remove unnecessary quotes. showPaths() already adds quotes. | Eelco Dolstra | 1 | -1/+1 | |
