| 2004-06-28 | * Added a switch `--fallback'. From the manual: | Eelco Dolstra | 17 | -58/+185 | |
| Whenever Nix attempts to realise a derivation for which a closure is already known, but this closure cannot be realised, fall back on normalising the derivation. The most common scenario in which this is useful is when we have registered substitutes in order to perform binary distribution from, say, a network repository. If the repository is down, the realisation of the derivation will fail. When this option is specified, Nix will build the derivation instead. Thus, binary installation falls back on a source installation. This option is not the default since it is generally not desirable for a transient failure in obtaining the substitutes to lead to a full build from source (with the related consumption of resources). | |||||
| 2004-06-25 | * A flag `--keep-going / -k' to keep building goals if one fails, as | Eelco Dolstra | 10 | -144/+209 | |
| much as possible. (This is similar to GNU Make's `-k' flag.) * Refactoring to implement this: previously we just bombed out when a build failed, but now we have to clean up. In particular this means that goals must be freed quickly --- they shouldn't hang around until the worker exits. So the worker now maintains weak pointers in order not to prevent garbage collection. * Documented the `-k' and `-j' flags. | |||||
| 2004-06-25 | * Don't throw an exception when a build fails. Just terminate the | Eelco Dolstra | 1 | -58/+214 | |
| goal and allow the problem to be handled elsewhere (e.g., at top-level). | |||||
| 2004-06-24 | * Obsolete. | Eelco Dolstra | 1 | -162/+0 | |
| 2004-06-24 | * Add a test to check that when we cannot realise a closure | Eelco Dolstra | 3 | -3/+26 | |
| expression, we should invalidate it and go back to the derivation for which it is a successor. | |||||
| 2004-06-24 | * Multiple and/or failing substitutes now work. | Eelco Dolstra | 4 | -19/+54 | |
| 2004-06-24 | * A test for multiple and/or failing substitutes. | Eelco Dolstra | 5 | -5/+80 | |
| 2004-06-22 | * Arghhhhhh | Eelco Dolstra | 1 | -1/+1 | |
| 2004-06-22 | * Some more diagnostics changes. | Eelco Dolstra | 2 | -25/+41 | |
| 2004-06-22 | * Nix-instantiate can return multiple store expressions. | Eelco Dolstra | 1 | -1/+3 | |
| 2004-06-22 | * A utility script `nix-build' that builds Nix expressions and prints | Eelco Dolstra | 2 | -6/+30 | |
| their output paths (and only that) on standard output. | |||||
| 2004-06-22 | * We don't really need this here. | Eelco Dolstra | 3 | -165/+0 | |
| 2004-06-22 | * Well, it's better than printf. | Eelco Dolstra | 1 | -1/+1 | |
| 2004-06-22 | * Started making Nix's diagnostic messages a bit more useful. | Eelco Dolstra | 1 | -10/+26 | |
| 2004-06-22 | * Put WEXITSTATUS stuff somewhere else. | Eelco Dolstra | 4 | -3/+11 | |
| 2004-06-22 | * Reduce gratuitous cut & pasting. | Eelco Dolstra | 1 | -68/+55 | |
| 2004-06-22 | * Wrapper class around pids. | Eelco Dolstra | 4 | -87/+162 | |
| 2004-06-22 | * Substitutes should occupy a build slot. | Eelco Dolstra | 1 | -1/+15 | |
| 2004-06-22 | * Refactoring. | Eelco Dolstra | 4 | -20/+25 | |
| 2004-06-21 | * Missing files added to `make dist'. | Eelco Dolstra | 1 | -1/+2 | |
| 2004-06-21 | * Remove debug output. | Eelco Dolstra | 1 | -1/+0 | |
| 2004-06-21 | * Adapted nix-pull to use the new substitute mechanism. | Eelco Dolstra | 8 | -58/+99 | |
| 2004-06-21 | * Acquire a lock on the output path when running a substitute. Also | Eelco Dolstra | 1 | -0/+22 | |
| delete obstructing invalid paths. | |||||
| 2004-06-21 | * Ugh, nasty Heisenbug due to an uninitialiased variable. The bug | Eelco Dolstra | 1 | -0/+1 | |
| only caused a crash if the program was *not* invoked with a high verbosity level. | |||||
| 2004-06-21 | * Remove obstructing invalid store paths add[Text]ToStore(). | Eelco Dolstra | 1 | -0/+6 | |
| 2004-06-21 | * Wrap calls to registerSubstitute() in a single transaction to | Eelco Dolstra | 3 | -11/+13 | |
| improve throughput. * Don't build the `substitute-rev' table for now, since it caused Theta(N^2) time and log file consumption when adding N substitutes. Maybe we can do without it. | |||||
| 2004-06-21 | * Disable calls to fsync() since Berkeley DB's DB_TXN_WRITE_NOSYNC | Eelco Dolstra | 1 | -0/+8 | |
| flag doesn't seem to work as advertised. | |||||
| 2004-06-20 | * Re-enable support for substitutes in the normaliser. | Eelco Dolstra | 10 | -108/+444 | |
| * A better substitute mechanism. Instead of generating a store expression for each store path for which we have a substitute, we can have a single store expression that builds a generic program that is invoked to build the desired store path, which is passed as an argument. This means that operations like `nix-pull' only produce O(1) files instead of O(N) files in the store when registering N substitutes. (It consumes O(N) database storage, of course, but that's not a performance problem). * Added a test for the substitute mechanism. * `nix-store --substitute' reads the substitutes from standard input, instead of from the command line. This prevents us from running into the kernel's limit on command line length. | |||||
| 2004-06-20 | * README for the Emacs mode (written a while ago, but forgot to commit). | Eelco Dolstra | 1 | -0/+10 | |
| 2004-06-20 | * Refactoring. | Eelco Dolstra | 3 | -41/+52 | |
| 2004-06-19 | * Re-enable build hooks. | Eelco Dolstra | 2 | -75/+327 | |
| 2004-06-18 | * Big refactoring. Move to a much more explicitly state machine based | Eelco Dolstra | 5 | -766/+874 | |
| approach. This makes it much easier to add extra complexity in the normaliser / realiser (e.g., build hooks, substitutes). | |||||
| 2004-06-18 | * This is also useful. | Eelco Dolstra | 3 | -1/+263 | |
| 2004-06-18 | * Shared (garbage collecting) pointers. Copied from Boost. | Eelco Dolstra | 12 | -17/+1268 | |
| 2004-06-15 | * Refactoring. | Eelco Dolstra | 3 | -83/+57 | |
| 2004-06-08 | * Cleanup. | Eelco Dolstra | 1 | -10/+17 | |
| 2004-06-04 | * A Nix mode for Emacs. | Eelco Dolstra | 6 | -2/+118 | |
| 2004-05-18 | * Drain the output of the build hook to show error messages. Ugly | Eelco Dolstra | 1 | -4/+26 | |
| hack. | |||||
| 2004-05-18 | * Don't set the rpath here --- it's not portable. | Eelco Dolstra | 1 | -2/+2 | |
| 2004-05-18 | * Go back to the old way of generating the system name, and allow it | Eelco Dolstra | 1 | -3/+6 | |
| to be specified in configure (using `--with-system=SYSTEM'). | |||||
| 2004-05-18 | * setpgrp() is not POSIX (and on Mac OS X it's different than on | Eelco Dolstra | 1 | -1/+1 | |
| Linux), so use setpgid(). | |||||
| 2004-05-14 | * execl() requires a terminating 0. | Eelco Dolstra | 1 | -10/+21 | |
| * When a fast build wakes up a goal, try to start that goal in the same iteration of the startBuild() loop of run(). Otherwise no job might be started until the next job terminates. | |||||
| 2004-05-13 | * Distributed builds and load balancing now seem to work pretty well. | Eelco Dolstra | 2 | -39/+101 | |
| (Though the `build-remote.pl' script has a gigantic race condition). | |||||
| 2004-05-13 | * Set the executable bit. | Eelco Dolstra | 1 | -0/+0 | |
| 2004-05-13 | * Load balancing. `build-remote.pl' will only execute up to a | Eelco Dolstra | 4 | -11/+34 | |
| per-machine maximum number of parallel jobs on a remote machine. | |||||
| 2004-05-13 | * Perform all tests. | Eelco Dolstra | 1 | -4/+2 | |
| 2004-05-13 | * The build hooks used to implement distributed builds can now be run | Eelco Dolstra | 9 | -144/+498 | |
| in parallel. Hooks are more efficient: locks on output paths are only acquired when the hook says that it is willing to accept a build job. Hooks now work in two phases. First, they should first tell Nix whether they are willing to accept a job. Nix guarantuees that no two hooks will ever be in the first phase at the same time (this simplifies the implementation of hooks, since they don't have to perform locking (?)). Second, if they accept a job, they are then responsible for building it (on the remote system), and copying the result back. These can be run in parallel with other hooks and locally executed jobs. The implementation is a bit messy right now, though. * The directory `distributed' shows a (hacky) example of a hook that distributes build jobs over a set of machines listed in a configuration file. | |||||
| 2004-05-12 | * Use `-j0'. | Eelco Dolstra | 1 | -8/+1 | |
| 2004-05-12 | * A switch `-j NUMBER' to set the maximum number of parallel jobs (0 = | Eelco Dolstra | 5 | -9/+30 | |
| no limit). * Add missing file to distribution. | |||||
| 2004-05-12 | * Broken test. | Eelco Dolstra | 1 | -3/+3 | |
