2012-02-15	Don't use deletePath() to delete a single file	Eelco Dolstra	1	-1/+1

2012-02-09	Use data() instead of c_str() where appropriate	Eelco Dolstra	4	-9/+9

2011-12-30	* Oops.	Eelco Dolstra	1	-1/+1

2011-12-30	* Move topoSortPaths() out of gc.cc.	Eelco Dolstra	2	-36/+36

2011-12-30	* Reject a build if there is a cycle among the outputs. This is	Eelco Dolstra	4	-9/+24
	necessary because existing code assumes that the references graph is acyclic.
2011-12-30	* Sync with the trunk.	Eelco Dolstra	3	-20/+44

2011-12-25	* Make sure that lock files are cleaned up properly when building	Eelco Dolstra	1	-7/+7
	through the build hook.
2011-12-22	* Oops.	Eelco Dolstra	1	-1/+1

2011-12-22	* In the garbage collector, delete invalid paths before deleting	Eelco Dolstra	1	-11/+35
	unreachable paths. This matters when using --max-freed etc.: unreachable paths could become reachable again, so it's nicer to keep them if there is "real" garbage to be deleted. Also, don't use readDirectory() but read the Nix store and delete invalid paths in parallel. This reduces GC latency on very large Nix stores.
2011-12-22	* Drop unnecessary call to canonPath() (nixStore is already canonical).	Eelco Dolstra	1	-1/+1

2011-12-21	* Another case of lock file permissions being too liberal.	Eelco Dolstra	1	-1/+1

2011-12-21	Revert previous commit	Shea Levy	1	-9/+0
	It doesn't detect indirect references
2011-12-21	Detect and reject mutually-referential outputs	Shea Levy	1	-0/+9
	There is probably a more efficient way to do this.
2011-12-20	* Fix the build.	Eelco Dolstra	1	-1/+1

2011-12-16	* Sync with the trunk.	Eelco Dolstra	12	-74/+157

2011-12-16	* importPath() -> importPaths(). Because of buffering of the input	Eelco Dolstra	6	-29/+45
	stream it's now necessary for the daemon to process the entire sequence of exported paths, rather than letting the client do it.
2011-12-16	* Make the import operation through the daemon much more efficient	Eelco Dolstra	3	-7/+8
	(way fewer roundtrips) by allowing the client to send data in bigger chunks. * Some refactoring.
2011-12-15	* Refactoring: move sink/source buffering into separate classes.	Eelco Dolstra	3	-9/+6
	* Buffer the HashSink. This speeds up hashing a bit because it prevents lots of calls to the hash update functions (e.g. nix-hash went from 9.3s to 8.7s of user time on the closure of my /var/run/current-system).
2011-12-14	* Buffer writes in FdSink. This significantly reduces the number of	Eelco Dolstra	1	-0/+4
	system calls / context switches when dumping a NAR and in the worker protocol.
2011-12-05	* Remove unnecessary quotes. showPaths() already adds quotes.	Eelco Dolstra	1	-1/+1

2011-12-02	* In ‘nix-store --verify --check-contents’, repair missing hashes	Eelco Dolstra	1	-4/+20
	rather than complain about them.
2011-12-01	* When doing "nix-store --add-fixed" without "--recursive" via the Nix	Eelco Dolstra	2	-4/+2
	daemon (which is an error), print a nicer error message than "Connection reset by peer" or "broken pipe". * In the daemon, log errors that occur during request parameter processing.
2011-11-29	* Get rid of some superfluous error messages if a substituter fails.	Eelco Dolstra	1	-15/+6
	* Say "fetch" instead of "substitute".
2011-11-23	* Add an API function exportPaths() that provides the functionality of	Eelco Dolstra	3	-1/+18
	‘nix-store --export’. * Add a Perl module that provides the functionality of ‘nix-copy-closure --to’. This is used by build-remote.pl so it no longer needs to start a separate nix-copy-closure process. Also, it uses the Perl API to do the export, so it doesn't need to start a separate nix-store process either. As a result, nix-copy-closure and build-remote.pl should no longer fail on very large closures due to an "Argument list too long" error. (Note that having very many dependencies in a single derivation can still fail because the environment can become too large. Can't be helped though.)
2011-11-22	* Move initialisation of variables like nixConfDir from libmain to	Eelco Dolstra	3	-2/+43
	libstore so that the Perl bindings can use it as well. It's vital that the Perl bindings use the configuration file, because otherwise nix-copy-closure will fail with a ‘database locked’ message if the value of ‘use-sqlite-wal’ is changed from the default.
2011-11-21	nix: add /etc/hosts with localhost entry to chroot builds.	Rob Vermaas	1	-0/+3

2011-11-07	* Boldly make SQLite WAL mode the default again. Hopefully the	Eelco Dolstra	1	-4/+3
	intermittent problems are gone by now. WAL mode is preferrable because it does way fewer fsyncs.
2011-11-06	Include all outputs of derivations in the closure of explicitly-passed ↵	Shea Levy	6	-0/+40
	derivation paths This required adding a queryOutputDerivationNames function in the store API
2011-09-12	* Ouch. A store upgrade could cause a substituter to be triggered,	Eelco Dolstra	3	-5/+6
	causing a deadlock.
2011-08-31	* Eliminate all uses of the global variable ‘store’ from libstore.	Eelco Dolstra	8	-61/+66
	This should also fix: nix-instantiate: ./../boost/shared_ptr.hpp:254: T* boost::shared_ptr<T>::operator->() const [with T = nix::StoreAPI]: Assertion `px != 0' failed. which was caused by hashDerivationModulo() calling the ‘store’ object (during store upgrades) before openStore() assigned it.
2011-07-20	* Fix a huuuuge security hole in the Nix daemon. It didn't check that	Eelco Dolstra	7	-16/+177
	derivations added to the store by clients have "correct" output paths (meaning that the output paths are computed by hashing the derivation according to a certain algorithm). This means that a malicious user could craft a special .drv file to build any desired path in the store with any desired contents (so long as the path doesn't already exist). Then the attacker just needs to wait for a victim to come along and install the compromised path. For instance, if Alice (the attacker) knows that the latest Firefox derivation in Nixpkgs produces the path /nix/store/1a5nyfd4ajxbyy97r1fslhgrv70gj8a7-firefox-5.0.1 then (provided this path doesn't already exist) she can craft a .drv file that creates that path (i.e., has it as one of its outputs), add it to the store using "nix-store --add", and build it with "nix-store -r". So the fake .drv could write a Trojan to the Firefox path. Then, if user Bob (the victim) comes along and does $ nix-env -i firefox $ firefox he executes the Trojan injected by Alice. The fix is to have the Nix daemon verify that derivation outputs are correct (in addValidPath()). This required some refactoring to move the hash computation code to libstore.
2011-06-30	Add support for the `build-timeout' and `--timeout' options.	Ludovic Courtès	3	-4/+35

2011-04-19	* Handle error messages from the Nix worker containing the `%'	Eelco Dolstra	1	-1/+1
	character. (Nix/216)
2010-12-17	* Do a short sleep after SQLITE_BUSY.	Eelco Dolstra	1	-0/+11

2010-12-17	* Propagate the "100" exit status for failed builds through the Nix	Eelco Dolstra	2	-3/+6
	daemon.
2010-12-14	* I forgot to catch SQLiteBusy in registerValidPaths(). So	Eelco Dolstra	1	-38/+31
	registerValidPaths() now handles busy errors and registerValidPath() is simply a wrapper around it.
2010-12-13	* nix-instantiate: return exit status 100 to denote a permanent build	Eelco Dolstra	1	-3/+16
	failure. The build hook can use this to distinguish between transient and permanent failures on the remote side.
2010-12-13	* Create /nix/var/nix/db if it's missing.	Eelco Dolstra	1	-0/+1

2010-12-13	* Update some comments.	Eelco Dolstra	1	-1/+1

2010-12-08	* Ignore the result of sqlite3_reset().	Eelco Dolstra	1	-3/+4

2010-12-06	* `nix-store --verify --check-contents': don't hold the global GC lock	Eelco Dolstra	2	-11/+49
	while checking the contents, since this operation can take a very long time to finish. Also, fill in missing narSize fields in the DB while doing this.
2010-12-05	* Retry a transaction if SQLite returns SQLITE_BUSY. This can happen	Eelco Dolstra	1	-61/+83
	even with a very long busy timeout, because SQLITE_BUSY is also returned to resolve deadlocks. This should get rid of random "database is locked" errors. This is kind of hard to test though. * Fix a horrible bug in deleteFromStore(): deletePathWrapped() should be called after committing the transaction, not before, because the commit might not succeed.
2010-11-17	* Before a build, show the disk space that the downloaded store paths	Eelco Dolstra	6	-6/+9
	will approximately require.
2010-11-17	* Add an operation `nix-store -q --size'.	Eelco Dolstra	2	-2/+13

2010-11-17	* Implement RemoteStore::queryPathInfo().	Eelco Dolstra	2	-1/+14

2010-11-16	* Store the size of a store path in the database (to be precise, the	Eelco Dolstra	11	-78/+124
	size of the NAR serialisation of the path, i.e., `nix-store --dump PATH'). This is useful for Hydra.
2010-11-16	* Sync with the trunk.	Eelco Dolstra	1	-3/+3

2010-10-14	* Wrap deleteFromStore() in a transaction. Otherwise there might be a	Eelco Dolstra	2	-8/+13
	race with other processes that add new referrers to a path, resulting in the garbage collector crashing with "foreign key constraint failed". (Nix/4) * Make --gc --print-dead etc. interruptible.
2010-10-04	* Make sure that config.h is included before the system headers,	Eelco Dolstra	1	-3/+3
	because it defines _FILE_OFFSET_BITS. Without this, on OpenSolaris the system headers define it to be 32, and then the 32-bit stat() ends up being called with a 64-bit "struct stat", or vice versa. This also ensures that we get 64-bit file sizes everywhere. * Remove the redundant call to stat() in parseExprFromFile(). The file cannot be a symlink because that's the exit condition of the loop before.
2010-09-01	* Only do "pragma journal_mode = ..." if the current journal mode	Eelco Dolstra	1	-1/+10
	differs from the desired mode. There is an open SQLite ticket `Executing "PRAGMA journal_mode" may delete journal file while it is in use.'
