2008-11-12 * Some somewhat ad hoc mechanism to allow the build farm to monitorEelco Dolstra1-0/+2
build progress.
2008-10-29 * Put the chroots under /nix/var/nix/chroots to reduce the risk ofEelco Dolstra1-0/+1
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.
2008-08-04 * `nix-store --realise': print what paths will be built/downloaded,Eelco Dolstra2-0/+31
just like nix-env. * `nix-store --realise': --dry-run option.
2008-08-04 * querySubstitutablePathInfo: work properly when run via the daemon.Eelco Dolstra1-1/+1
* --dry-run: print the paths that we don't know how to build/substitute.
2008-07-18 * Use the copy-from-other-stores substituter by default. Of course,Eelco Dolstra1-3/+4
it only does something if $NIX_OTHER_STORES (not really a good name...) is set. * Do globbing on the elements of $NIX_OTHER_STORES. E.g. you could set it to /mnts/*/nix or something. * Install substituters in libexec/nix/substituters.
2008-06-18 * --max-freed: support values >= 4 GB.Eelco Dolstra2-3/+3
2008-06-18 * Garbage collector: option `--max-freed' to stop after at least NEelco Dolstra2-1/+4
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).
2008-06-14 * nix-worker: clean up the temporary root for the worker processes Eelco Dolstra2-9/+11
in /nix/var/nix/temproots.
2007-11-16 * Flag `--no-build-hook' to disable distributed builds.Eelco Dolstra1-0/+2
* queryDeriver in daemon mode: don't barf if the other side returns an empty string (which means there is no deriver).
2007-08-12 * Get rid of the substitutes database table (NIX-47). Instead, if weEelco Dolstra1-1/+7
need any info on substitutable paths, we just call the substituters (such as download-using-manifests.pl) directly. This means that it's no longer necessary for nix-pull to register substitutes or for nix-channel to clear them, which makes those operations much faster (NIX-95). Also, we don't have to worry about keeping nix-pull manifests (in /nix/var/nix/manifests) and the database in sync with each other. The downside is that there is some overhead in calling an external program to get the substitutes info. For instance, "nix-env -qas" takes a bit longer. Abolishing the substitutes table also makes the logic in local-store.cc simpler, as we don't need to store info for invalid paths. On the downside, you cannot do things like "nix-store -qR" on a substitutable but invalid path (but nobody did that anyway). * Never catch interrupts (the Interrupted exception).
2007-05-01 * Set a terminate() handler to ensure that we leave the BDBEelco Dolstra1-0/+24
environment cleanly even when an exception is thrown from a destructor. We still crash, but we don't take all other Nix processes with us.
2007-03-30 * Work around a bug in Apple's GCC preprocessor.Eelco Dolstra1-2/+2
2007-01-14 * Option --argstr for passing string arguments easily. (NIX-75)Eelco Dolstra1-1/+1
2007-01-13 * Removed chroot support.Eelco Dolstra1-6/+0
2006-12-08 * Kill a build if it has gone for more than a certain number ofEelco Dolstra1-14/+18
seconds without producing output on stdout or stderr (NIX-65). This timeout can be specified using the `--max-silent-time' option or the `build-max-silent-time' configuration setting. The default is infinity (0). * Fix a tricky race condition: if we kill the build user before the child has done its setuid() to the build user uid, then it won't be killed, and we'll potentially lock up in pid.wait(). So also send a conventional kill to the child.
2006-12-07 * Move setuidCleanup() to libutil.Eelco Dolstra2-25/+0
2006-12-06 * nix-setuid-helper: allow running programs under a different uid.Eelco Dolstra2-11/+24
2006-12-05 * Allow unprivileged users to run the garbage collector and to doEelco Dolstra1-1/+0
`nix-store --delete'. But unprivileged users are not allowed to ignore liveness. * `nix-store --delete --ignore-liveness': ignore the runtime roots as well.
2006-12-05 * In addPermRoot, check that the root that we just registered can beEelco Dolstra1-1/+1
found by the garbage collector. This addresses NIX-71 and is a particular concern in multi-user stores.
2006-12-04 * Daemon mode (`nix-worker --daemon'). Clients connect to the serverEelco Dolstra1-0/+6
via the Unix domain socket in /nix/var/nix/daemon.socket. The server forks a worker process per connection. * readString(): use the heap, not the stack. * Some protocol fixes.
2006-12-04 * Install the worker in bindir, not libexecdir.Eelco Dolstra2-0/+2
* Allow the worker path to be overriden through the NIX_WORKER environment variable.
2006-12-03 * Doh.Eelco Dolstra2-1/+4
2006-12-03 * Don't run setuid root when build-users is empty.Eelco Dolstra1-1/+1
* Send startup errors to the client.
2006-12-03 * Removed `build-allow-root'.Eelco Dolstra2-0/+5
* Added `build-users-group', the group under which builds are to be performed. * Check that /nix/store has 1775 permission and is owner by the build-users-group.
2006-12-03 * Use setreuid if setresuid is not available.Eelco Dolstra1-6/+12
2006-12-02 * Remove most of the old setuid code.Eelco Dolstra1-4/+56
* Much simpler setuid code for the worker in slave mode.
2006-11-30 * Refactoring. There is now an abstract interface class StoreAPIEelco Dolstra1-2/+3
containing functions that operate on the Nix store. One implementation is LocalStore, which operates on the Nix store directly. The next step, to enable secure multi-user Nix, is to create a different implementation RemoteStore that talks to a privileged daemon process that uses LocalStore to perform the actual operations.
2006-11-18 * Turn off synchronisation between C and C++ I/O functions. ThisEelco Dolstra1-0/+2
gives a huge speedup in operations that read or write from standard input/output. (So libstdc++'s I/O isn't that bad, you just have to call std::ios::sync_with_stdio(false).) For instance, `nix-store --register-substitutes' went from 1.4 seconds to 0.1 seconds on a certain input. Another victory for Valgrind.
2006-09-27 * Fix setuid builds.Eelco Dolstra1-4/+0
2006-09-04 * Move setuid stuff to libutil.Eelco Dolstra1-133/+0
* Install libexpr header files.
2006-09-04 * Don't need extern "C".Eelco Dolstra1-2/+0
2006-09-04 * Use a proper namespace.Eelco Dolstra2-14/+27
* Optimise header file usage a bit. * Compile the parser as C++.
2006-09-04 * Store the Nix libraries in ${libdir}/nix instead of ${libdir}.Eelco Dolstra1-1/+1
2006-08-29 * Support singleton values and nested lists again in `args', but printEelco Dolstra1-7/+4
a warning.
2006-08-10 * New configuration setting `build-max-jobs' which sets the defaultEelco Dolstra1-0/+7
for the `-j' flag (i.e., the maximum number of jobs to execute in parallel). Useful on multi-processor machines.
2006-07-20 * Use $(libexecdir) to find find-runtime-roots.pl.Eelco Dolstra2-0/+2
2006-07-06 * Allow the canonical system name to be specified at runtime in theEelco Dolstra1-0/+2
Nix config file.
2006-05-12 * Support for srcdir != builddir (NIX-41).Eelco Dolstra1-1/+2
2006-03-10 * Allow `make check' to work in directories that have symlinkEelco Dolstra1-23/+2
components.
2006-03-01 * Close the database before the destructor runs.Eelco Dolstra1-0/+3
2006-01-09 * dirOf: return "/", not "", for paths in the root directory. Fixes NIX-26.Eelco Dolstra1-1/+1
2005-11-04 * Install signal handlers for SIGTERM and SIGHUP. This ensures thatEelco Dolstra1-0/+4
Nix is properly shut down when it receives those signals. In particular this ensures that killing the garbage collector doesn't cause a subsequent database recovery.
2005-10-17 * Beginning of secure multi-user Nix stores. If Nix is started asEelco Dolstra1-0/+5
root (or setuid root), then builds will be performed under one of the users listed in the `build-users' configuration variables. This is to make it impossible to influence build results externally, allowing locally built derivations to be shared safely between users (see ASE-2005 paper). To do: only one builder should be active per build user.
2005-07-22 * Build dynamic libraries.Eelco Dolstra1-2/+2
2005-02-01 * A GC setting `gc-keep-outputs' to specify whether output paths ofEelco Dolstra2-0/+2
derivations should be kept.
2005-02-01 * nix-store, nix-instantiate: added an option `--add-root' toEelco Dolstra2-1/+27
immediately add the result as a permanent GC root. This is the only way to prevent a race with the garbage collector. For instance, the old style ln -s $(nix-store -r $(nix-instantiate foo.nix)) \ /nix/var/nix/gcroots/result has two time windows in which the garbage collector can interfere (by GC'ing the derivation and the output, respectively). On the other hand, nix-store --add-root /nix/var/nix/gcroots/result -r \ $(nix-instantiate --add-root /nix/var/nix/gcroots/drv \ foo.nix) is safe. * nix-build: use `--add-root' to prevent GC races.
2005-01-31 * Automatically remove temporary root files.Eelco Dolstra1-0/+14
2005-01-28 * Use NIX_STORE environment variable to locate the store (in additionEelco Dolstra1-1/+1
to NIX_STORE_DIR) so that Nix invocations in builders in `make check' work correctly if the store doesn't exist.
2005-01-19 * Renamed `normalise.cc' -> `build.cc', `storeexprs.cc' ->Eelco Dolstra1-2/+2
`derivations.cc', etc. * Store the SHA-256 content hash of store paths in the database after they have been built/added. This is so that we can check whether the store has been messed with (a la `rpm --verify'). * When registering path validity, verify that the closure property holds.
2005-01-14 * Start move towards SHA-256 hashes instead of MD5.Eelco Dolstra1-4/+4
* Start cleaning up unique store path generation (they weren't always unique; in particular the suffix ("-aterm-2.2", "-builder.sh") was not part of the hash, therefore changes to the suffix would cause multiple store objects with the same hash).
