2009-03-23	* No longer block while waiting for a lock on a store path. Instead	Eelco Dolstra	5	-28/+85
	poll for it (i.e. if we can't acquire the lock, then let the main select() loop wait for at most a few seconds and then try again). This improves parallelism: if two nix-store processes are both trying to build a path at the same time, the second one shouldn't block; it should first see if it can build other goals. Also, it prevents the deadlocks that have been occuring in Hydra lately, where a process waits for a lock held by another process that's waiting for a lock held by the first. The downside is that polling isn't really elegant, but POSIX doesn't provide a way to wait for locks in a select() loop. The only solution would be to spawn a thread for each lock to do a blocking fcntl() and then signal the main thread, but that would require pthreads.
2009-03-22	* Refactoring.	Eelco Dolstra	1	-136/+85

2009-03-22	* Test case (currently fails): multiple Nix builds shouldn't block	Eelco Dolstra	1	-2/+34
	waiting on the same lock when there are other builds that can be done.
2009-03-22	* Better error message when nix-store --import is applied to garbage	Eelco Dolstra	1	-1/+1
	(previously it would likely say "implementation cannot deal with > 32-bit integers").
2009-03-22	* NAR archives: handle files larger than 2^32 bytes. Previously it	Eelco Dolstra	7	-17/+48
	would just silently store only (fileSize % 2^32) bytes. * Use posix_fallocate if available when unpacking archives. * Provide a better error message when trying to unpack something that isn't a NAR archive.
2009-03-19	* Future proofing: assume we can read manifests up to version 10	Eelco Dolstra	1	-1/+6
	(which should therefore be backwards compatible).
2009-03-19	* Disregard the Hash field in manifests.	Eelco Dolstra	1	-22/+5

2009-03-18	* Unify exportReferencesGraph and exportBuildReferencesGraph, and make	Eelco Dolstra	4	-67/+40
	sure that it works as expected when you pass it a derivation. That is, we have to make sure that all build-time dependencies are built, and that they are all in the input closure (otherwise remote builds might fail, for example). This is ensured at instantiation time by adding all derivations and their sources to inputDrvs and inputSrcs.
2009-03-18	* Improve the test.	Eelco Dolstra	1	-2/+6

2009-03-18	* Better cleanup after tests.	Eelco Dolstra	1	-5/+8

2009-03-18	* Missing file.	Eelco Dolstra	1	-0/+1

2009-03-18	* Acquire the locks on the output paths before trying to run the build	Eelco Dolstra	4	-150/+78
	hook. This fixes a problem with log files being partially or completely filled with 0's because another nix-store process truncates the log file. It should also be more efficient.
2009-03-18	* Clean up some tests (use nix-build where appropriate).	Eelco Dolstra	7	-34/+25

2009-03-17	* Regression test for exportBuildReferencesGraph. It currently fails.	Eelco Dolstra	3	-6/+34

2009-03-17	* Refactoring: renamed .nix.in to .nix.	Eelco Dolstra	22	-264/+209

2009-03-17	* Regression test for the `exportReferencesGraph'	Eelco Dolstra	8	-33/+69
	derivation attribute.
2009-03-17	* Cleanup.	Eelco Dolstra	1	-22/+9

2009-03-09	* Make the version available to release.nix.	Eelco Dolstra	3	-41/+15

2009-03-06	(no commit message)	Eelco Dolstra	1	-1/+1

2009-03-06	(no commit message)	Eelco Dolstra	1	-1/+1

2009-03-05	* Install some headers in the right location.	Eelco Dolstra	2	-2/+6

2009-03-03	* Allow the channel to declare a name for itself.	Eelco Dolstra	1	-0/+6

2009-02-27	* nix-install-package: don't pollute /nix/var/nix/manifests.	Eelco Dolstra	3	-11/+11

2009-02-27	* Use the regular progress bar; the hash bar isn't very useful when	Eelco Dolstra	1	-1/+1
	the size of the download isn't known in advance.
2009-02-27	* nix-build: support --option.	Eelco Dolstra	1	-0/+7

2009-02-27	* Allow options from the Nix config file to be overriden from the	Eelco Dolstra	3	-0/+21
	command line (e.g. "--option build-use-chroot true").
2009-02-27	* nix-channel: use nix-build.	Eelco Dolstra	1	-8/+6

2009-02-27	* Check the manifest version.	Eelco Dolstra	1	-3/+4

2009-02-26	* Handle base-16 hashes in manifests.	Eelco Dolstra	1	-1/+12

2009-02-19	* download-using-manifests: don't check the cryptographic hash of	Eelco Dolstra	1	-18/+30
	downloaded files; rather, check the hash of the unpacked store path. When the server produces bzipped NAR archives on demand (like Hydra does), the hash of the file is not known in advance; it's streamed from the server. Thus the manifest doesn't contain a hash for the bzipped NAR archive. However, the server does know the hash of the uncompressed NAR archive (the "NarHash" field), since it's stored in the Nix database (nix-store -q --hash /nix/store/bla). So we use that instead for checking the integrity of the download.
2009-02-19	Replace wrong (w.r.t. PATH) sed call with in-shell substitution	Michael Raskin	1	-1/+2

2009-02-16	* Release output locks as soon as possible, not when the destructor of	Eelco Dolstra	3	-0/+14
	the DerivationGoal runs. Otherwise, if a goal is a top-level goal, then the lock won't be released until nix-store finishes. With --keep-going and lots of top-level goals, it's possible to run out of file descriptors (this happened sometimes in the build farm for Nixpkgs). Also, for failed derivation, it won't be possible to build it again until the lock is released. * Idem for locks on build users: these weren't released in a timely manner for failed top-level derivation goals. So if there were more than (say) 10 such failed builds, you would get an error about having run out of build users.
2009-02-05	documentation for previous commit	Marc Weber	1	-0/+30

2009-02-05	added primop functions __isBool, __isString, __isInt	Marc Weber	1	-0/+25

2009-02-03	* Build hook: compress the transferred data.	Eelco Dolstra	1	-2/+2

2009-02-02	* Build hooks: use nix-store --import. This prevents a redundant	Eelco Dolstra	3	-22/+29
	scan for runtime dependencies (i.e. the local machine shouldn't do a scan that the remote machine has already done). Also pipe directly into `nix-store --import': don't use a temporary file.
2009-01-28	vim syntax: support for indented strings ('' .. '')	Marc Weber	1	-1/+3

2009-01-27	Add the "addErrorContext" builtin to add more information in the stack trace.	Nicolas Pierron	1	-0/+14

2009-01-27	* Make it compile on Debian 4.0 (which doesn't define PER_LINUX32_3GB	Eelco Dolstra	1	-1/+1
	in sys/personality.h).
2009-01-13	* When using a build hook, distinguish between transient failures	Eelco Dolstra	2	-6/+30
	(e.g. an SSH connection problem) and permanent failures (i.e. the builder failed). This matters to Hydra (it wants to know whether it makes sense to retry a build).
2009-01-13	(no commit message)	Eelco Dolstra	1	-1/+1

2009-01-12	* Support i686-linux builds directly on x86_64-linux Nix	Eelco Dolstra	2	-2/+24
	installations. This is implemented using the personality() syscall, which causes uname to return "i686" in child processes.
2009-01-12	* Make Nix build with Bison 2.4.	Eelco Dolstra	1	-0/+1

2009-01-05	* Removed reference to losser.st-lab.cs.uu.nl, which is RIP after 9	Eelco Dolstra	1	-1/+1
	years of loyal service :-)
2008-12-16	* nix-store --verify: repair bad hash fields in the metadata file.	Eelco Dolstra	2	-5/+16

2008-12-16	* Pass --use-atime / --max-atime to the daemon.	Eelco Dolstra	3	-1/+9

2008-12-15	* Delete the chroot if it already exists (e.g. left over from an	Eelco Dolstra	1	-0/+1
	interrupted build).
2008-12-12	* Put chroots in the Nix store. This ensures that we can create hard	Eelco Dolstra	2	-2/+14
	links to the inputs.
2008-12-12	* Simplify deleting .lock files in /nix/store: just don't delete them	Eelco Dolstra	4	-34/+38
	if they belong a path that's currently being built. This gets rid of some Cygwin-specific code.
2008-12-12	* Some hackery to make "make check" succeed on Cygwin.	Eelco Dolstra	2	-0/+15
