2007-11-29 * nix-env -e: support uninstalling by path, so that one can sayEelco Dolstra1-2/+1
$ nix-env -e $(which firefox) or $ nix-env -e /nix/store/nywzlygrkfcgz7dfmhm5xixlx1l0m60v-pan-0.132 * nix-env -i: if an argument contains a slash anywhere, treat it as a path and follow it through symlinks into the Nix store. This allows things like $ nix-build -A firefox $ nix-env -i ./result * nix-env -q/-i/-e: don't complain when the `*' selector doesn't match anything. In particular, `nix-env -q \*' doesn't fail anymore on an empty profile.
2007-10-27 * Delete the chroot directory automatically.Eelco Dolstra1-4/+4
* Removed some debug messages.
2007-10-27 * Support for doing builds in a chroot under Linux. The builder isEelco Dolstra1-9/+23
executed in a chroot that contains just the Nix store, the temporary build directory, and a configurable set of additional directories (/dev and /proc by default). This allows a bit more purity enforcement: hidden build-time dependencies on directories such as /usr or /nix/var/nix/profiles are no longer possible. As an added benefit, accidental network downloads (cf. NIXPKGS-52) are prevented as well (because files such as /etc/resolv.conf are not available in the chroot). However the usefulness of chroots is diminished by the fact that many builders depend on /bin/sh, so you need /bin in the list of additional directories. (And then on non-NixOS you need /lib as well...)
2007-09-17 * nix-env: allow ~/.nix-defexpr to be a directory. If it is, then theEelco Dolstra1-0/+1
Nix expressions in that directory are combined into an attribute set {file1 = import file1; file2 = import file2; ...}, i.e. each Nix expression is an attribute with the file name as the attribute name. Also recurses into directories. * nix-env: removed the "--import" (-I) option which set the ~/.nix-defexpr symlink. * nix-channel: don't use "nix-env --import", instead symlink ~/.nix-defexpr/channels. So finally nix-channel --update doesn't override any default Nix expressions but combines with them. This means that you can have (say) a local Nixpkgs SVN tree and use it as a default for nix-env: $ ln -s .../path-to-nixpkgs-tree ~/.nix-defexpr/nixpkgs_svn and be subscribed to channels (including Nixpkgs) at the same time. (If there is any ambiguity, the -A flag can be used to disambiguate, e.g. "nix-env -i -A nixpkgs_svn.pan".)
2007-08-12 * Get rid of the substitutes database table (NIX-47). Instead, if weEelco Dolstra1-2/+5
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 Dolstra1-3/+17
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.
2007-03-19 * Terminate build hooks and substitutes with a TERM signal, not a KILLEelco Dolstra1-4/+12
signal. This is necessary because those processes may have joined the BDB environment, so they have to be given a chance to clean up. (NIX-85)
2007-02-21 * `nix-store --import': import an archive created by `nix-storeEelco Dolstra1-5/+5
--export' into the Nix store, and optionally check the cryptographic signatures against /nix/etc/nix/signing-key.pub. (TODO: verify against a set of public keys.)
2007-02-21 * `nix-store --export --sign': sign the Nix archive using the RSA keyEelco Dolstra1-3/+12
in /nix/etc/nix/signing-key.sec
2006-12-07 * Move setuidCleanup() to libutil.Eelco Dolstra1-0/+16
2006-12-07 * Change the ownership of store paths to the Nix account beforeEelco Dolstra1-1/+1
deleting them using the setuid helper.
2006-12-07 * Move killUser() to libutil so that the setuid helper can use it.Eelco Dolstra1-0/+47
2006-12-05 * The determination of the root set should be made by the privilegedEelco Dolstra1-0/+1
process, so forward the operation. * Spam the user about GC misconfigurations (NIX-71). * findRoots: skip all roots that are unreadable - the warnings with which we spam the user should be enough.
2006-12-04 * Daemon mode (`nix-worker --daemon'). Clients connect to the serverEelco Dolstra1-14/+3
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.
2006-12-03 * Pid::kill() should be interruptable.Eelco Dolstra1-1/+3
2006-12-03 * Some hackery to propagate the worker's stderr and exceptions to theEelco Dolstra1-1/+10
client.
2006-12-02 * Move addTempRoot() to the store API, and add another functionEelco Dolstra1-2/+2
syncWithGC() to allow clients to register GC roots without needing write access to the global roots directory or the GC lock.
2006-12-02 * Remove most of the old setuid code.Eelco Dolstra1-130/+1
* Much simpler setuid code for the worker in slave mode.
2006-12-02 * Remove SwitchToOriginalUser, we're not going to need it anymore.Eelco Dolstra1-31/+0
2006-11-29 * Don't spam.Eelco Dolstra1-0/+2
2006-11-29 * Example script to set permissions for setuid operation.Roy van den Broek1-1/+1
2006-11-29 * Remove --enable-setuid, --with-nix-user and --with-nix-group.Eelco Dolstra1-26/+45
Rather, setuid support is now always compiled in (at least on platforms that have the setresuid system call, e.g., Linux and FreeBSD), but it must enabled by chowning/chmodding the Nix binaries.
2006-11-24 * Doh! Path sizes need to be computed recursively of course.Eelco Dolstra1-0/+23
(NIX-70)
2006-10-30 * readFile: don't overflow the stack on large files.Eelco Dolstra1-1/+15
2006-09-27 * Fix setuid builds.Eelco Dolstra1-5/+9
2006-09-04 * Move setuid stuff to libutil.Eelco Dolstra1-0/+136
* Install libexpr header files.
2006-09-04 * Use a proper namespace.Eelco Dolstra1-12/+14
* Optimise header file usage a bit. * Compile the parser as C++.
2006-08-29 * Fix the ~ operator.Eelco Dolstra1-0/+9
2006-08-26 * Refactoring.Eelco Dolstra1-4/+9
2006-08-04 * Weird issue on Cygwin with the include file order.Eelco Dolstra1-4/+4
2006-07-20 * Call find-runtime-roots.pl from the garbage collector to preventEelco Dolstra1-0/+84
running applications etc. from being garbage collected.
2006-07-06 * Allow the canonical system name to be specified at runtime in theEelco Dolstra1-3/+0
Nix config file.
2006-06-19 * Write messages to stderr in a slightly more atomic way. Useful whenEelco Dolstra1-1/+2
there are several parallel processes.
2006-06-14 * Fix for a problem with BSD's group ownership semantics when the user Eelco Dolstra1-1/+13
is not in the "wheel" group.
2006-05-11 * 64-bit compatibility fixes (for problems revealed by building on an AthlonEelco Dolstra1-2/+2
64 running 64-bit SUSE). A patched ATerm library is required to run Nix succesfully.
2006-03-08 * Some refactoring of the exception handling code so that we can catchEelco Dolstra1-0/+7
Nix expression assertion failures.
2006-01-09 * dirOf: return "/", not "", for paths in the root directory. Fixes NIX-26.Eelco Dolstra1-2/+2
2006-01-08 * Resolve all symlink components in the location of the temporaryEelco Dolstra1-2/+21
build directory (TMPDIR, i.e., /tmp). Fixes NIX-26.
2005-12-15 * `nix-store --gc' prints out the number of bytes freed on stdoutEelco Dolstra1-3/+13
(even when it is interrupted by a signal).
2005-09-22 * Parse multi-valued options.Eelco Dolstra1-0/+15
2005-05-04 * The eof() state isn't guaranteed to be set non-lazily. GCC 2.95Eelco Dolstra1-1/+1
compatibility fix.
2005-03-24 * Create missing log and temproots directories automatically (reportedEelco Dolstra1-0/+10
by Rob).
2005-02-09 * Automatically upgrade <= 0.7 Nix stores to the new schema (so thatEelco Dolstra1-0/+9
existing user environments continue to work). * `nix-store --verify': detect incomplete closures.
2005-02-01 * A GC setting `gc-keep-outputs' to specify whether output paths ofEelco Dolstra1-0/+21
derivations should be kept.
2005-02-01 * nix-build: use an indirection scheme to make it easier for users toEelco Dolstra1-0/+9
get rid of GC roots. Nix-build places a symlink `result' in the current directory. Previously, removing that symlink would not remove the store path being linked to as a GC root. Now, the GC root created by nix-build is actually a symlink in `/nix/var/nix/gcroots/auto' to `result'. So if that symlink is removed the GC root automatically becomes invalid (since it can no longer be resolved). The root itself is not automatically removed - the garbage collector should delete dangling roots.
2005-01-31 * Topologically sort paths under the references relation to ensureEelco Dolstra1-1/+0
that they are deleted in an order that maintains the closure invariant. * Presence of a path in a temporary roots file does not imply that all paths in its closure are also present, so add the closure.
2005-01-31 * Start of concurrent garbage collection. Processes write temporaryEelco Dolstra1-3/+10
roots to a per-process temporary file in /nix/var/nix/temproots while holding a write lock on that file. The garbage collector acquires read locks on all those files, thus blocking further progress in other Nix processes, and reads the sets of temporary roots.
2005-01-27 * Make lock removal safe by signalling to blocked processes that theEelco Dolstra1-0/+9
lock they are waiting on has become stale (we do this by writing a meaningless token to the unlinked file).
2005-01-20 * Another change to low-level derivations. The last one this year, IEelco Dolstra1-0/+2
promise :-) This allows derivations to specify on *what* output paths of input derivations they are dependent. This helps to prevent unnecessary downloads. For instance, a build might be dependent on the `devel' and `lib' outputs of some library component, but not the `docs' output.
2004-11-08 * Fix broken format string.Eelco Dolstra1-1/+1
