2003-07-29 * `fstateRefs' now works on derive expressions as well. TODO: makeEelco Dolstra4-14/+40
this more efficient. * A flag `-n' in 'nix --query' to normalise the argument. Default is not to normalise.
2003-07-29 * Let `nix --install' print out the id of the normal form.Eelco Dolstra5-34/+35
* Some minor refactoring.
2003-07-28 * Do not set LD_LIBRARY_PATH; it breaks many things. E.g., SuSE's ssh Eelco Dolstra1-1/+1
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. Instead, all packages should use rpaths to store library locations in executables/libraries. The disadvantage is that overriding rpaths is harder. (It is possible by invoking the dynamic linker directly, e.g., `/lib/ld-linux.so.2 --ignore-path LIST program args...' to ignore the rpath for the libraries in LIST). It would be better to use DT_RUNPATH, which is consulted by the dynamic linker *after* LD_LIBRARY_PATH but *before* ld.so.cache and the system directories.
2003-07-28 * Check for the pthread library (db4 needs it on some platforms).Eelco Dolstra2-1/+4
2003-07-28 * `nix --help'.Eelco Dolstra3-37/+116
* `nix --query --graph' to print a dot dependency graph of derive expressions.
2003-07-24 * Fix message.Eelco Dolstra1-1/+2
2003-07-24 * Prevent spurious rebuilds of db/aterm.Eelco Dolstra1-2/+10
2003-07-24 * The `-v' flag no longer takes an argument; it should be repeatedEelco Dolstra6-38/+29
instead (e.g., `-vvvv' for lots of output). Default is to only print error messages.
2003-07-24 * Do sync the database, since not doing so caused database changes notEelco Dolstra1-1/+1
to reach the disk at all. Looks like a bug.
2003-07-24 * Debug levels. Use `--verbose / -v LEVEL' to display only messagesEelco Dolstra8-25/+68
up to the given verbosity levels. These currently are: lvlError = 0, lvlNormal = 5, lvlDebug = 10, lvlDebugMore = 15 although only lvlError and lvlDebug are actually used right now.
2003-07-24 * Don't sync the database on close. This was killing performance.Eelco Dolstra1-1/+1
(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.)
2003-07-23 * Incorporated Berkeley DB and ATerm into the source tree.Eelco Dolstra7-5/+63
* `make dist'.
2003-07-22 * libdb_cxx-4 -> libdb_cxxEelco Dolstra1-4/+4
2003-07-22 * Substitutes now should produce a path with the same id as they areEelco Dolstra8-50/+86
substituting for (obvious, really). * For greater efficiency, nix-pull/unnar will place the output in a path that is probably the same as what is actually needed, thus preventing a path copy. * Even if a output id is given in a Fix package expression, ensure that the resulting Nix derive expression has a different id. This is because Nix expressions that are semantically equivalent (i.e., build the same result) might be different w.r.t. efficiency or divergence. It is absolutely vital for the substitute mechanism that such expressions are not used interchangeably.
2003-07-22 * `nix --query --expansion' (`-qe') to get any path with contentEelco Dolstra1-3/+13
corresponding to the given id.
2003-07-21 * Changed nix-pull to match nix-push.Eelco Dolstra2-15/+16
2003-07-21 * Syntax fixes.Eelco Dolstra4-17/+32
* When pushing, put the hash in the file name so that the client can verify (proof-carrying file names?).
2003-07-21 * In `--query --generators', print out paths, not ids.Eelco Dolstra1-1/+1
(There should really be a switch for this).
2003-07-21 * Check for errors.Eelco Dolstra1-1/+1
2003-07-21 * Canonicalise path.Eelco Dolstra1-1/+1
2003-07-21 * Allow the output/expression id to be forced to a certain Eelco Dolstra6-17/+23
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.
2003-07-21 * Changes to the command line syntax of Nix.Eelco Dolstra5-78/+117
* 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.
2003-07-21 * Memoize the evaluation of Fix expressions to speed up computation.Eelco Dolstra2-25/+47
2003-07-20 * Argh, another short-write problem. Added wrappers aroundEelco Dolstra9-36/+46
read()/write() to fix this once and for all.
2003-07-20 * Remove accidentally added file.Eelco Dolstra1-0/+0
2003-07-20 * Refactorings.Eelco Dolstra14-587/+617
2003-07-18 * Generate nar.sh, fetchurl.sh.Eelco Dolstra9-27/+32
2003-07-17 * For debugging: `nix --verify' to check the consistency of theEelco Dolstra7-14/+139
database and store.
2003-07-17 * Preserve the executable bit.Eelco Dolstra1-0/+13
2003-07-16 * The write() system call can write less than the requested Eelco Dolstra3-3/+13
number of bytes, e.g., in case of a signal like SIGSTOP. This caused `nix --dump' to fail sometimes. Note that this bug went unnoticed because the call to `nix --dump' is in a pipeline, and the shell ignores non-zero exit codes from all but the last element in the pipeline. Is there any way to check the result of the initial elements in the pipeline? (In other words, is it at all possible to write reliable shell scripts?)
2003-07-16 * Doh!Eelco Dolstra1-1/+2
2003-07-16 * Bug fix: slices are transitive, so if we detect that an Eelco Dolstra1-5/+10
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.
2003-07-16 * Substitute fixes.Eelco Dolstra8-36/+86
2003-07-16 * Fix the -qr query.Eelco Dolstra3-15/+40
2003-07-16 * Fix self-referential outputs.Eelco Dolstra5-30/+28
* Fix -qp query.
2003-07-15 * Get Fix and Nix to work again.Eelco Dolstra6-268/+93
2003-07-15 * The new normaliser now passes the unit tests.Eelco Dolstra7-34/+179
2003-07-15 * Basic work on allowing derive expressions to build multiple paths.Eelco Dolstra7-193/+366
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.
2003-07-14 * Get the garbage collector to work again.Eelco Dolstra2-22/+25
2003-07-14 * After building, scan for actual file system references asEelco Dolstra7-12/+149
opposed to declared references. This prunes the reference graph, thus allowing better garbage collection and more efficient derivate distribution.
2003-07-13 * Don't check for staleness by default.Eelco Dolstra1-0/+3
2003-07-13 * Pass $(prefix) and other variables through -D..., not Eelco Dolstra2-15/+17
through config.h, to prevent silly Autoconf problems.
2003-07-13 * Generate the scripts so that we can substitute the prefixEelco Dolstra6-24/+23
etc. correctly. * Fixed nix-switch.
2003-07-12 * Fetchurl: check md5 checksum.Eelco Dolstra2-3/+10
2003-07-11 * Fix a bug that caused Fix not to be deterministic (due to addToStoreEelco Dolstra3-9/+9
returning different paths if the hash of the path to be added was already available in the store under a different name).
2003-07-11 * Fix handling of pipes (read(2) may not return the requiredEelco Dolstra1-5/+7
number of bytes in one call).
2003-07-10 * Compress Nix archives when pushing them.Eelco Dolstra4-5/+7
2003-07-10 * Working derivate sharing.Eelco Dolstra2-4/+23
2003-07-10 * Convert tabs to spaces.Eelco Dolstra2-70/+70
2003-07-10 * A command to register successor fstate expressions.Eelco Dolstra3-1/+28
Unifying substitutes and successors isn't very feasible for now, since substitutes are only used when no path with a certain is known. Therefore, a normal form of some expression stored as a substitute would not be used unless the expression itself was missing.
