2e16ff22ac * Fix man page. Eelco Dolstra 2003-08-14 11:27:02 +0000
5cde23f869 * Function() takes a list of formals. Eelco Dolstra 2003-08-14 09:49:31 +0000
0a2de7f543 * Lam -> Function. Doh! Eelco Dolstra 2003-08-14 09:29:07 +0000
95b49f8044 * Manual updates. Eelco Dolstra 2003-08-13 15:17:57 +0000
68022552d2 * Put the pre-built manual and man pages in the tar distribution. Eelco Dolstra 2003-08-13 15:17:36 +0000
c34a153ae5 * Documented the `--query' operation. Eelco Dolstra 2003-08-13 10:45:01 +0000
b4f88d0ec3 * Split the book.xml into several xml files. Eelco Dolstra 2003-08-13 09:13:52 +0000
469f1eba56 * Documented some Nix operations. Eelco Dolstra 2003-08-12 15:06:49 +0000
e405ca506e * Generate man pages from the manual. Eelco Dolstra 2003-08-12 13:54:42 +0000
c602930e08 * deletePath(): some operating systems (e.g., Mac OS X) don't like it when we delete entries from a directory while we are reading it. So read the directory into memory, then delete its contents. Eelco Dolstra 2003-08-08 14:55:56 +0000
4b7b0bd12c * Started on the introduction. Eelco Dolstra 2003-08-07 15:27:14 +0000
74867e72f2 * Start of manual; installation instructions. Eelco Dolstra 2003-08-07 14:17:18 +0000
f8035d06f2 * Allow a name to be given to a system configuration through --name NAME'. E.g., on the losser Subversion server, I do nix-switch --name svn $(fix ...)' to atomically upgrade the server (the SVN server uses the Apache and Subversion installations in /nix/var/nix/links/svn). Eelco Dolstra 2003-08-06 14:48:29 +0000
9ad39df282 * `==' is not a valid operator. Eelco Dolstra 2003-08-06 10:00:30 +0000
d551062ec4 * Scan for wget and use the full path in fetchurl.sh. * Use nix-hash (not md5sum) in fetchurl.sh. Eelco Dolstra 2003-08-06 09:35:05 +0000
236eb59293 * Allow locks on paths to be acquired recursively (that is, if the process is already holding a lock on a path, it may acquire the lock again without blocking or failing). (This might be dangerous, not sure). Necessary for fast builds to work. Eelco Dolstra 2003-08-06 09:34:04 +0000
720f06e3b0 * A flag --flat' to just compute the MD5 checksum of the contents of a regular file. I.e., nix-hash --flat' is equivalent to the coreutils `md5sum' command (which doesn't exist on all systems). Eelco Dolstra 2003-08-06 09:06:32 +0000
37483672d4 * App -> Call. * Allow booleans in package environment bindings (True maps to "1", False maps to ""). Eelco Dolstra 2003-08-06 09:05:04 +0000
d34b4d4f28 * Conditionals. Eelco Dolstra 2003-08-05 13:05:30 +0000
b9c9b461ea * Made nix-push much faster. Eelco Dolstra 2003-08-05 12:30:06 +0000
4ce652640b * Cache result of fstatePaths(). TODO: do this in fstore.cc. Eelco Dolstra 2003-08-05 12:29:47 +0000
fd30f52cfc * Made nix-pull much faster by performing all Fix instantiations at the same time. Eelco Dolstra 2003-08-05 11:14:24 +0000
17f05dba77 * Allow the top-level expression to be a list of expressions that normalise to Nix expression. Eelco Dolstra 2003-08-05 11:13:38 +0000
d6b6b2d3a8 * Delete obstructed paths prior to building. Eelco Dolstra 2003-08-05 09:47:20 +0000
d2e963f7a3 * Path locking in addToStore() and expandPath(). Eelco Dolstra 2003-08-04 07:09:36 +0000
c95b4ad290 * In normaliseFState(), wrap registration of the output paths and the normal form in a single transaction to ensure that if we crash, either everything is registered or nothing is. This is for recoverability: unregistered paths in the store can be deleted arbitrarily, while registered paths can only be deleted by running the garbage collector. Eelco Dolstra 2003-08-01 15:41:47 +0000
d99d04e644 * Defensive programming against POSIX locking idiocy. * Simplified realiseSlice(). Eelco Dolstra 2003-08-01 15:06:23 +0000
545145cd58 * normaliseFState() now locks all output paths prior to building, thus ensuring that simultaneous invocations of Nix don't clobber each other's builds. Eelco Dolstra 2003-08-01 14:11:19 +0000
9df93f30bd * Don't use substitutes in addToStore(). Eelco Dolstra 2003-08-01 09:01:51 +0000
06434072e7 * Put the database verifier in a transaction. Eelco Dolstra 2003-07-31 19:49:11 +0000
06d3d7355d * Enclose most operations that update the database in transactions. Eelco Dolstra 2003-07-31 16:05:35 +0000
177a7782ae * Use a more reasonable log file size (256 KB instead of 10 MB). * Checkpoint on exit. Eelco Dolstra 2003-07-31 14:28:49 +0000
4a013962bd * Started using Berkeley DB environments. This is necessary for transaction support (but we don't actually use transactions yet). Eelco Dolstra 2003-07-31 13:47:13 +0000
758bd4673a * Set execute bit. Eelco Dolstra 2003-07-31 13:13:27 +0000
9f4c19276d * Basic makefile. Eelco Dolstra 2003-07-31 13:13:13 +0000
26ff1cdf89 * A better test case for Nix race conditions. Eelco Dolstra 2003-07-30 14:40:46 +0000
64c617e984 * Directories for the manual. Eelco Dolstra 2003-07-30 14:40:18 +0000
2ac02440dc * Test cases for races. Eelco Dolstra 2003-07-30 13:35:46 +0000
aaee69cfde * INSTALL_DATA -> INSTALL_PROGRAM to ensure that the execute bit remains set. Eelco Dolstra 2003-07-30 10:14:58 +0000
83075304e5 * Don't make the builder executable. Eelco Dolstra 2003-07-30 09:49:47 +0000
1cb030736e * Bug: Fix does not allow empty names, so don't generate them. Eelco Dolstra 2003-07-29 17:56:39 +0000
a01629894d * Use --query --requisites' and include successors when pushing. Don't use --query --generators' anymore. Eelco Dolstra 2003-07-29 15:19:03 +0000
40f32ae00a * Typo: if -> elsif. Eelco Dolstra 2003-07-29 14:42:14 +0000
8846465934 * Get garbage collection and cache population to work *properly*. Renamed fstateRefs' to fstateRequisites'. The semantics of this function is that it returns a list of all paths necessary to realise a given expression. For a derive expression, this is the union of requisites of the inputs; for a slice expression, it is the path of each element in the slice. Also included are the paths of the expressions themselves. Optionally, one can also include the requisites of successor expressions (to recycle intermediate results). Eelco Dolstra 2003-07-29 14:28:17 +0000
dc14a3de46 * Nicer dot graphs. Eelco Dolstra 2003-07-29 10:53:27 +0000
79ba0431db * fstateRefs' now works on derive expressions as well. TODO: make this more efficient. * A flag -n' in 'nix --query' to normalise the argument. Default is not to normalise. Eelco Dolstra 2003-07-29 10:43:12 +0000
5acb45446e * Let `nix --install' print out the id of the normal form. * Some minor refactoring. Eelco Dolstra 2003-07-29 09:45:03 +0000
ce5fd1cc12 * Do not set LD_LIBRARY_PATH; it breaks many things. E.g., SuSE's ssh dynamically links against libdb4 (?!), due to LD_LIBRARY_PATH it picks up our libdb4 instead of SuSE's libdb4, but our libdb4 uses another glibc so loading barfs. Eelco Dolstra 2003-07-28 16:07:01 +0000
dec8fbc52b * Check for the pthread library (db4 needs it on some platforms). Eelco Dolstra 2003-07-28 14:13:42 +0000
949c4fa1a8 * nix --help'. * nix --query --graph' to print a dot dependency graph of derive expressions. Eelco Dolstra 2003-07-28 12:19:23 +0000
f21b341957 * Fix message. Eelco Dolstra 2003-07-24 15:03:36 +0000
5d7a20dac3 * Prevent spurious rebuilds of db/aterm. Eelco Dolstra 2003-07-24 14:31:39 +0000
0a0c1fcb4d * The -v' flag no longer takes an argument; it should be repeated instead (e.g., -vvvv' for lots of output). Default is to only print error messages. Eelco Dolstra 2003-07-24 13:43:16 +0000
3b521bb1bd * Do sync the database, since not doing so caused database changes not to reach the disk at all. Looks like a bug. Eelco Dolstra 2003-07-24 13:35:17 +0000
1a7468a57a * Debug levels. Use `--verbose / -v LEVEL' to display only messages up to the given verbosity levels. These currently are: Eelco Dolstra 2003-07-24 08:53:43 +0000
b75719b984 * Don't sync the database on close. This was killing performance. (Of course, the real problem is that we open the database for *every* operation; we should only open it once. And we should use transactions.) Eelco Dolstra 2003-07-24 08:24:32 +0000
39ce70025b * Incorporated Berkeley DB and ATerm into the source tree. * `make dist'. Eelco Dolstra 2003-07-23 15:53:34 +0000
9202570f8c * libdb_cxx-4 -> libdb_cxx Eelco Dolstra 2003-07-22 20:02:33 +0000
e877c69d78 * Substitutes now should produce a path with the same id as they are substituting for (obvious, really). Eelco Dolstra 2003-07-22 15:15:15 +0000
df648c4967 * nix --query --expansion' (-qe') to get any path with content corresponding to the given id. Eelco Dolstra 2003-07-22 10:24:22 +0000
d84931ee56 * Changed nix-pull to match nix-push. Eelco Dolstra 2003-07-21 22:05:19 +0000
c7bdb76fe4 * Syntax fixes. * When pushing, put the hash in the file name so that the client can verify (proof-carrying file names?). Eelco Dolstra 2003-07-21 21:34:56 +0000
d5ee6f8700 * In `--query --generators', print out paths, not ids. (There should really be a switch for this). Eelco Dolstra 2003-07-21 21:31:03 +0000
2616e6a6f3 * Check for errors. Eelco Dolstra 2003-07-21 20:58:34 +0000
9f4ad99e92 * Canonicalise path. Eelco Dolstra 2003-07-21 20:58:21 +0000
249988a787 * Allow the output/expression id to be forced to a certain value; this potentially dangerous feature enables better sharing for those paths for which the content is known in advance (e.g., because a content hash is given). * Fast builds: if we can expand all output paths of a derive expression, we don't have to build. Eelco Dolstra 2003-07-21 20:07:12 +0000
49231fbe41 * Changes to the command line syntax of Nix. * A function to find all Nix expressions whose output ids are completely contained in some set. Useful for uploading relevant Nix expressions to a shared cache. Eelco Dolstra 2003-07-21 14:46:01 +0000
401452e57a * Memoize the evaluation of Fix expressions to speed up computation. Eelco Dolstra 2003-07-21 08:55:49 +0000
7984cfc7c1 * Argh, another short-write problem. Added wrappers around read()/write() to fix this once and for all. Eelco Dolstra 2003-07-20 21:11:43 +0000
667a6afb9d * Remove accidentally added file. Eelco Dolstra 2003-07-20 19:30:53 +0000
6f1a0f948d * Refactorings. Eelco Dolstra 2003-07-20 19:29:38 +0000
ab350eafd2 * Generate nar.sh, fetchurl.sh. Eelco Dolstra 2003-07-18 07:42:57 +0000
b3fc38bf6a * For debugging: `nix --verify' to check the consistency of the database and store. Eelco Dolstra 2003-07-17 12:27:55 +0000
71cc3ceae5 * Preserve the executable bit. Eelco Dolstra 2003-07-17 11:25:14 +0000
54664b6fb7 * The write() system call can write less than the requested number of bytes, e.g., in case of a signal like SIGSTOP. This caused `nix --dump' to fail sometimes. Eelco Dolstra 2003-07-16 21:24:02 +0000
335aa1c35d * Doh! Eelco Dolstra 2003-07-16 20:49:59 +0000
6822fd7bf4 * Bug fix: slices are transitive, so if we detect that an input path is referenced in an output paths, we also have to add all ids referenced by that input path. * Better debug assertions to catch these sorts of errors. Eelco Dolstra 2003-07-16 20:33:29 +0000
9d56ca219f * Substitute fixes. Eelco Dolstra 2003-07-16 20:00:51 +0000
b9ecadee6e * Fix the -qr query. Eelco Dolstra 2003-07-16 11:05:59 +0000
c11bbcfd26 * Fix self-referential outputs. * Fix -qp query. Eelco Dolstra 2003-07-16 08:30:26 +0000
d41d085b77 * Get Fix and Nix to work again. Eelco Dolstra 2003-07-15 22:28:27 +0000
7b3f44e05b * The new normaliser now passes the unit tests. Eelco Dolstra 2003-07-15 21:24:05 +0000
f5b6fa5256 * Basic work on allowing derive expressions to build multiple paths. This is not entirely trivial since this introduces the possibility of mutual recursion. * Made normal forms self-contained. * Use unique ids, not content hashes, for content referencing. Eelco Dolstra 2003-07-15 16:28:54 +0000
8898e86b4f * Get the garbage collector to work again. Eelco Dolstra 2003-07-14 10:45:04 +0000
3509299aca * After building, scan for actual file system references as opposed to declared references. This prunes the reference graph, thus allowing better garbage collection and more efficient derivate distribution. Eelco Dolstra 2003-07-14 10:23:11 +0000
135b7d54db * Don't check for staleness by default. Eelco Dolstra 2003-07-13 21:43:57 +0000
e6363b05ae * Pass $(prefix) and other variables through -D..., not through config.h, to prevent silly Autoconf problems. Eelco Dolstra 2003-07-13 19:26:00 +0000
9c620e4afa * Generate the scripts so that we can substitute the prefix etc. correctly. * Fixed nix-switch. Eelco Dolstra 2003-07-13 18:58:03 +0000
5304a1eb3a * Fetchurl: check md5 checksum. Eelco Dolstra 2003-07-12 11:03:14 +0000
73b163c1a1 * Fix a bug that caused Fix not to be deterministic (due to addToStore returning different paths if the hash of the path to be added was already available in the store under a different name). Eelco Dolstra 2003-07-11 08:41:03 +0000
c834a5c597 * Fix handling of pipes (read(2) may not return the required number of bytes in one call). Eelco Dolstra 2003-07-11 08:16:15 +0000
822c072cfa * Compress Nix archives when pushing them. Eelco Dolstra 2003-07-10 20:34:29 +0000
9bcc31c941 * Working derivate sharing. Eelco Dolstra 2003-07-10 20:13:32 +0000
