* Started implementing the new evaluation model. * Lots of refactorings. * Unit tests. 2003-06-16 15:33:38 +02:00			`#include "globals.hh"`

* Realisation of File(...) expressions. 2003-06-27 15:55:12 +02:00			`string nixStore = "/UNINIT";`
* Get `nix-push' working again. It now uses Nix/Fix to create Nix archives (using the package in corepkgs/nar). * queryPathByHash -> expandHash, and it takes an argument specifying the target path (which may be empty). * Install the core Fix packages in $prefix/share/fix. TODO: bootstrap Nix and install Nix as a Fix package. 2003-07-10 15:41:28 +02:00			`string nixDataDir = "/UNINIT";`
* Started implementing the new evaluation model. * Lots of refactorings. * Unit tests. 2003-06-16 15:33:38 +02:00			`string nixLogDir = "/UNINIT";`
* nix-env: a tool to manage user environments. * Replace all directory reading code by a generic readDirectory() function. 2003-11-19 18:27:16 +01:00			`string nixStateDir = "/UNINIT";`
* Started using Berkeley DB environments. This is necessary for transaction support (but we don't actually use transactions yet). 2003-07-31 15:47:13 +02:00			`string nixDBPath = "/UNINIT";`

* Delete the temporary directories of failed builds by default, and an option `--keep-failed' to override this behaviour. 2003-08-19 11:04:47 +02:00			`bool keepFailed = false;`
* Option `-B' to always show the output of builders, regardless of verbosity level. 2004-01-13 17:35:43 +01:00
* A flag `--keep-going / -k' to keep building goals if one fails, as 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 17:36:09 +02:00			`bool keepGoing = false;`

* Added a switch `--fallback'. From the manual: 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). 2004-06-28 12:42:57 +02:00			`bool tryFallback = false;`

* The default verbosity level of all Nix commands is now lvlInfo. * Builder output is written to standard error by default. * The option `-B' is gone. * The option `-Q' suppresses builder output. The result of this is that most Nix invocations shouldn't need any flags w.r.t. logging. 2004-08-18 14:19:06 +02:00			`Verbosity buildVerbosity = lvlInfo;`
* A switch `-j NUMBER' to set the maximum number of parallel jobs (0 = no limit). * Add missing file to distribution. 2004-05-12 16:20:32 +02:00
			`unsigned int maxBuildJobs = 1;`
* Allow certain operations to succeed even if we don't have write permission to the Nix store or database. E.g., `nix-env -qa' will work, but `nix-env -qas' won't (the latter needs DB access). The option `--readonly-mode' forces this mode; otherwise, it's only activated when the database cannot be opened. 2004-10-25 16:38:23 +02:00
