2010-03-23	(no commit message)	Eelco Dolstra	1	-1/+1

2010-02-24	* Don't use fdatasync since it doesn't work on Snow Leopard.	Eelco Dolstra	1	-6/+0
	* Don't refer to config.h in util.hh, because config.h is not installed (http://hydra.nixos.org/build/303053).
2010-02-02	* If fdatasync() isn't available, use fsync().	Eelco Dolstra	1	-0/+4

2010-01-29	* Added an option "fsync-metadata" to fsync() changes to	Eelco Dolstra	1	-5/+1
	/nix/var/nix/db. * Removed the function writeStringToFile since it does (almost) the same thing as writeFile.
2009-12-17	* Include config.h before the C library headers, because it defines	Eelco Dolstra	1	-0/+2
	_FILE_OFFSET_BITS=64. Without it, functions like stat() fail on large file sizes. This happened with a Nix store on squashfs: $ nix-store --dump /tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds > /dev/null error: getting attributes of path `/tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds': Value too large for defined data type $ stat /tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds File: `/tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds' Size: 0 Blocks: 36028797018963968 IO Block: 1024 regular empty file (This is a bug in squashfs or mksquashfs, but it shouldn't cause Nix to fail.)
2009-11-24	* Grrr.	Eelco Dolstra	1	-1/+1

2009-11-24	* GCC 4.4 is stricter about the EOF macro	Eelco Dolstra	1	-0/+2
	(http://hydra.nixos.org/build/156340).
2009-11-24	* Templatise getIntArg / string2Int.	Eelco Dolstra	1	-2/+7

2009-03-28	* Simplify communication with the hook a bit (don't use file	Eelco Dolstra	1	-0/+6
	descriptors 3/4, just use stdin/stderr).
2008-09-17	* Garbage collector: added an option `--use-atime' to delete paths in	Eelco Dolstra	1	-0/+23
	order of ascending last access time. This is useful in conjunction with --max-freed or --max-links to prefer deleting non-recently used garbage, which is good (especially in the build farm) since garbage may become live again. The code could easily be modified to accept other criteria for ordering garbage by changing the comparison operator used by the priority queue in collectGarbage().
2008-08-25	* Strip off the `.nix' suffix from the attribute name for files in	Eelco Dolstra	1	-0/+4
	~/.nix-defexpr, otherwise the attribute cannot be selected with the `-A' option. Useful if you want to stick a Nix expression directly in ~/.nix-defexpr.
2008-08-02	* Make nix-env --dry-run print the paths to be substituted correctly	Eelco Dolstra	1	-0/+4
	again. (After the previous substituter mechanism refactoring I didn't update the code that obtains the references of substitutable paths.) This required some refactoring: the substituter programs are now kept running and receive/respond to info requests via stdin/stdout.
2008-06-18	* --max-freed: support values >= 4 GB.	Eelco Dolstra	1	-0/+1

2008-06-18	* Some refactoring: put the GC options / results in separate structs.	Eelco Dolstra	1	-3/+5
	* The garbage collector now also prints the number of blocks freed.
2008-06-09	* Merged the no-bdb branch (-r10900:HEAD	Eelco Dolstra	1	-0/+4
	https://svn.nixos.org/repos/nix/nix/branches/no-bdb).
2008-03-27	* Use /tmp/nix-build-<drvpath>-<counter> instead of	Eelco Dolstra	1	-1/+2
	/tmp/nix-<pid>-<counter> for temporary build directories. This increases purity a bit: many packages store the temporary build path in their output, causing (generally unimportant) binary differences.
2007-10-27	* Delete the chroot directory automatically.	Eelco Dolstra	1	-1/+1
	* Removed some debug messages.
2007-10-27	* Support for doing builds in a chroot under Linux. The builder is	Eelco Dolstra	1	-3/+5
	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...)
2007-08-12	* Get rid of the substitutes database table (NIX-47). Instead, if we	Eelco Dolstra	1	-1/+1
	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 BDB	Eelco Dolstra	1	-0/+5
	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 KILL	Eelco Dolstra	1	-0/+2
	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-store	Eelco Dolstra	1	-1/+1
	--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 key	Eelco Dolstra	1	-1/+2
	in /nix/etc/nix/signing-key.sec
2006-12-12	* New primop builtins.filterSource, which can be used to filter files	Eelco Dolstra	1	-2/+2
	from a source directory. All files for which a predicate function returns true are copied to the store. Typical example is to leave out the .svn directory: stdenv.mkDerivation { ... src = builtins.filterSource (path: baseNameOf (toString path) != ".svn") ./source-dir; # as opposed to # src = ./source-dir; } This is important because the .svn directory influences the hash in a rather unpredictable and variable way.
2006-12-07	* Move setuidCleanup() to libutil.	Eelco Dolstra	1	-0/+4

2006-12-07	* Move killUser() to libutil so that the setuid helper can use it.	Eelco Dolstra	1	-0/+5

2006-12-04	* Daemon mode (`nix-worker --daemon'). Clients connect to the server	Eelco Dolstra	1	-0/+17
	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	* Some hackery to propagate the worker's stderr and exceptions to the	Eelco Dolstra	1	-0/+2
	client.
2006-12-02	* Remove most of the old setuid code.	Eelco Dolstra	1	-4/+0
	* Much simpler setuid code for the worker in slave mode.
2006-12-02	* Remove SwitchToOriginalUser, we're not going to need it anymore.	Eelco Dolstra	1	-6/+0

2006-11-24	* Doh! Path sizes need to be computed recursively of course.	Eelco Dolstra	1	-0/+3
	(NIX-70)
2006-09-04	* Move setuid stuff to libutil.	Eelco Dolstra	1	-3/+3
	* Install libexpr header files.
2006-09-04	* Use a proper namespace.	Eelco Dolstra	1	-54/+5
	* Optimise header file usage a bit. * Compile the parser as C++.
2006-08-29	* Fix the ~ operator.	Eelco Dolstra	1	-0/+2

2006-08-26	* Refactoring.	Eelco Dolstra	1	-0/+1

2006-07-20	* Call find-runtime-roots.pl from the garbage collector to prevent	Eelco Dolstra	1	-0/+14
	running applications etc. from being garbage collected.
2006-07-06	* Allow the canonical system name to be specified at runtime in the	Eelco Dolstra	1	-4/+0
	Nix config file.
2006-03-08	* Some refactoring of the exception handling code so that we can catch	Eelco Dolstra	1	-5/+9
	Nix expression assertion failures.
2006-01-08	* Resolve all symlink components in the location of the temporary	Eelco Dolstra	1	-2/+4
	build directory (TMPDIR, i.e., /tmp). Fixes NIX-26.
2005-12-15	* `nix-store --gc' prints out the number of bytes freed on stdout	Eelco Dolstra	1	-1/+4
	(even when it is interrupted by a signal).
2005-09-22	* Parse multi-valued options.	Eelco Dolstra	1	-0/+4

2005-03-24	* Create missing log and temproots directories automatically (reported	Eelco Dolstra	1	-0/+3
	by Rob).
2005-02-11	* Refactoring to support different installation sources in nix-env.	Eelco Dolstra	1	-0/+8
	* Set the references for the user environment manifest properly. * Don't copy the manifest (this was accidental). * Don't store derivation paths in the manifest (maybe this should be made optional). This cleans up the semantics of nix-env, which were weird. * Hash on the output paths of activated components, not on derivation paths. This is because we don't know the derivation path of already installed components anymore, and it allows the installation of components by store path (skipping Nix expressions entirely). * Query options `--out-path' and `--drv-path' to show the output and derivation paths of components, respectively (the latter replaces the `--expr' query).
2005-02-09	* Automatically upgrade <= 0.7 Nix stores to the new schema (so that	Eelco Dolstra	1	-0/+3
	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 of	Eelco Dolstra	1	-0/+4
	derivations should be kept.
2005-02-01	* nix-build: use an indirection scheme to make it easier for users to	Eelco Dolstra	1	-0/+2
	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	* Start of concurrent garbage collection. Processes write temporary	Eelco Dolstra	1	-1/+2
	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 the	Eelco Dolstra	1	-0/+1
	lock they are waiting on has become stale (we do this by writing a meaningless token to the unlinked file).
2004-09-10	* Operation `--delete-generations' to delete generations of a	Eelco Dolstra	1	-0/+4
	profile. Arguments are either generation number, or `old' to delete all non-current generations. Typical use: $ nix-env --delete-generations old $ nix-collect-garbage * istringstream -> string2Int.
2004-09-09	* A very dirty hack to make setuid installations a bit nicer to use.	Eelco Dolstra	1	-0/+10
	Previously there was the problem that all files read by nix-env etc. should be reachable and readable by the Nix user. So for instance building a Nix expression in your home directory meant that the home directory should have at least g+x or o+x permission so that the Nix user could reach the Nix expression. Now we just switch back to the original user just prior to reading sources and the like. The places where this happens are somewhat arbitrary, however. Any scope that has a live SwitchToOriginalUser object in it is executed as the original user. * Back out r1385. setreuid() sets the saved uid to the new real/effective uid, which prevents us from switching back to the original uid. setresuid() doesn't have this problem (although the manpage has a bug: specifying -1 for the saved uid doesn't leave it unchanged; an explicit value must be specified).
