| 2010-08-25 | * Made the build hook mechanism more efficient. Rather than starting | Eelco Dolstra | 1 | -203/+187 | |
| the hook every time we want to ask whether we can run a remote build (which can be very often), we now reuse a hook process for answering those queries until it accepts a build. So if there are N derivations to be built, at most N hooks will be started. | |||||
| 2010-08-24 | * Don't complain if the stored hash of a path is zero (unknown). | Eelco Dolstra | 1 | -2/+3 | |
| 2010-08-24 | * Handle the unlikely case where a derivation has no dependencies at | Eelco Dolstra | 1 | -1/+4 | |
| all. | |||||
| 2010-08-24 | * Sync with the trunk. | Eelco Dolstra | 3 | -1/+7 | |
| 2010-08-12 | * Make --cores work when building through the Nix daemon. | Eelco Dolstra | 3 | -1/+7 | |
| 2010-08-04 | * Sync with the trunk. | Eelco Dolstra | 12 | -21/+62 | |
| 2010-08-04 | * Use SQLite 3.7.0's write-ahead logging (WAL mode). This is a lot | Eelco Dolstra | 1 | -2/+12 | |
| faster than the old mode when fsyncs are enabled, because it only performs an fsync() when doing a checkpoint, rather than at every commit. Some timings for doing a "nix-instantiate /etc/nixos/nixos -A system" after modifying the stdenv setup script: 42.5s - SQLite 3.6.23 with truncate mode and fsync 3.4s - SQLite 3.6.23 with truncate mode and no fsync 32.1s - SQLite 3.7.0 with truncate mode and fsync 16.8s - SQLite 3.7.0 with WAL mode and fsync, auto-checkpoint every 1000 pages 8.3s - SQLite 3.7.0 with WAL mode and fsync, auto-checkpoint every 8192 pages 1.7s - SQLite 3.7.0 with WAL mode and no fsync The default is now to use WAL mode with fsyncs. Because WAL doesn't work on remote filesystems such as NFS (as it uses shared memory), truncate mode can be re-enabled by setting the "use-sqlite-wal" option to false. | |||||
| 2010-08-04 | * Remove "auto" and "guess" as synonyms for 0 in the handling of | Eelco Dolstra | 1 | -14/+3 | |
| build-cores and --cores. They're superfluous and just complicate the parsing. | |||||
| 2010-08-04 | * Allow derivations to hint that they should not be built remotely | Eelco Dolstra | 1 | -23/+39 | |
| using the build hook mechanism, by setting the derivation attribute "preferLocalBuild" to true. This has a few use cases: - The user environment builder. Since it just creates a bunch of symlinks without much computation, there is no reason to do it remotely. In fact, doing it remotely requires the entire closure of the user environment to be copied to the remote machine, which is extremely wasteful. - `fetchurl'. Performing the download on a remote machine and then copying it to the local machine involves twice as much network traffic as performing the download locally, and doesn't save any CPU cycles on the local machine. | |||||
| 2010-08-04 | * Set the default system filter to "*". This ensures that (for | Eelco Dolstra | 1 | -7/+13 | |
| instance) "nix-env -i wine" works on x86_64-linux, even though Wine is built on i686-linux. In the event that there are multiple matching derivations, prefer those built for the current system. | |||||
| 2010-08-02 | * Optimisation in the // operator: if one of the sets is empty, return | Eelco Dolstra | 1 | -6/+8 | |
| the other set. | |||||
| 2010-08-02 | * intersectAttrs: optimise for the case where the second set is larger | Eelco Dolstra | 1 | -7/+7 | |
| than the first set. (That's usually the case with callPackage.) | |||||
| 2010-07-15 | src/bsdiff-4.3/Makefile.am: include the 'compat-include' directory in ↵ | Peter Simons | 1 | -0/+2 | |
| distribution tarballs | |||||
| 2010-06-24 | Fix build of bsdiff-4.3 on machines that don't have <err.h>, such as Solaris. | Peter Simons | 2 | -1/+13 | |
| 2010-06-24 | src/libutil/util.cc: include <limit.h> to ensure that PATH_MAX is defined | Peter Simons | 1 | -0/+1 | |
| 2010-06-24 | Include <cstring> to ensure that strcpy(), strlen(), and memset() are declared. | Peter Simons | 3 | -0/+6 | |
| An "using namespace std" was added locally in those functions that refer to names from <cstring>. That is not pretty, but it's a very portable solution, because strcpy() and friends will be found in both the 'std' and in the global namespace. | |||||
| 2010-06-23 | Added support for passing an (impure) NIX_BUILD_CORES variable to build ↵ | Peter Simons | 4 | -0/+23 | |
| expressions. This patch adds the configuration file variable "build-cores" and the command line argument "--cores". These settings specify the number of CPU cores to utilize for parallel building within a job, i.e. by passing an appropriate "-j" flag to GNU Make. The default value is 1, which means that parallel building is *disabled*. If the number of build cores is specified as 0 (synonymously: "guess" or "auto"), then the actual value is supposed to be auto-detected by builders at run-time, i.e by calling the nproc(1) utility from coreutils. The environment variable $NIX_BUILD_CORES is available to builders, but the contents of that variable does *not* influence the hash that goes into the $out store path, i.e. the number of build cores to be utilized can be changed at will without requiring any re-builds. | |||||
| 2010-06-21 | * Okay, putting a lock on the temporary directory used by importPath() | Eelco Dolstra | 2 | -6/+20 | |
| doesn't work because the garbage collector doesn't actually look at locks. So r22253 was stupid. Use addTempRoot() instead. Also, locking the temporary directory in exportPath() was silly because it isn't even in the store. | |||||

| 2010-06-08 | * Replacing ValidPath rows doesn't work because it causes a constraint | Eelco Dolstra | 1 | -2/+5 | |
