| 2010-11-29 | * Don't generate patches if the system type differs. | Eelco Dolstra | 2 | -2/+13 | |
| 2010-11-29 | * Impose a configurable time limit on patch generation. This is | Eelco Dolstra | 1 | -6/+12 | |
| necessary because bsdiff has some pathological worst-case behaviour, e.g. O(n^2) on files consisting only of 0s. | |||||
| 2010-11-25 | * Sync with the trunk. | Eelco Dolstra | 1 | -0/+4 | |
| 2010-11-25 | * DrvInfo contains pointers to expressions, so DrvInfos should be | Eelco Dolstra | 1 | -0/+4 | |
| traced by the garbage collector. Otherwise "nix-env -u" can crash randomly. | |||||
| 2010-11-17 | * Test whether sequences of patches work. | Eelco Dolstra | 2 | -15/+37 | |
| 2010-11-17 | * Oops. | Eelco Dolstra | 1 | -1/+1 | |
| 2010-11-17 | * When checking whether a patch is applicable, for efficiency, use | Eelco Dolstra | 1 | -3/+7 | |
| `nix-store -q --hash' to get the hash of the base path rather than `nix-hash'. However, only do this for estimating the size of a download, not for the actual substitution, because sometimes the contents of store paths are modified (which they shouldn't, of course). | |||||
| 2010-11-17 | * In the download size indication, take binary patches into account. | Eelco Dolstra | 3 | -145/+168 | |
| Hopefully this doesn't slow things down too much. | |||||
| 2010-11-17 | (no commit message) | Eelco Dolstra | 1 | -0/+1 | |
| 2010-11-17 | * Finally, a test for the binary patch functionality. | Eelco Dolstra | 5 | -3/+56 | |
| 2010-11-17 | * Test that download sizes are shown correctly. | Eelco Dolstra | 2 | -2/+4 | |
| 2010-11-17 | * Fix the test. | Eelco Dolstra | 2 | -0/+2 | |
| 2010-11-17 | * Before a build, show the disk space that the downloaded store paths | Eelco Dolstra | 11 | -29/+36 | |
| will approximately require. | |||||
| 2010-11-17 | * Store the NAR size in the manifest. | Eelco Dolstra | 2 | -1/+7 | |
| 2010-11-17 | * nix-push: no need to compute the NAR hash, since the Nix database | Eelco Dolstra | 2 | -9/+5 | |
| already has it (`nix-store -q --hash'). | |||||
| 2010-11-17 | * Add an operation `nix-store -q --size'. | Eelco Dolstra | 5 | -10/+40 | |
| 2010-11-17 | * Implement RemoteStore::queryPathInfo(). | Eelco Dolstra | 3 | -1/+27 | |
| 2010-11-16 | * Store the size of a store path in the database (to be precise, the | Eelco Dolstra | 16 | -91/+144 | |
| 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 | 37 | -444/+722 | |
| 2010-10-29 | * Merge the GC branch. | Eelco Dolstra | 30 | -413/+678 | |
| 2010-10-29 | * Document Boehm GC support. | Eelco Dolstra | 4 | -1/+40 | |
| 2010-10-29 | * Use pkgconfig to locate the Boehm GC (as suggested by Ludo), if | Eelco Dolstra | 2 | -10/+10 | |
| --enable-gc is given. | |||||
| 2010-10-29 | * Set libgc's initial heap size to 384 MiB to prevent garbage | Eelco Dolstra | 1 | -0/+12 | |
| collection in most cases (and therefore its performance overhead). | |||||
| 2010-10-28 | * new(UseGC) is inexplicably slower than GC_MALLOC, so prefer the | Eelco Dolstra | 1 | -4/+4 | |
| latter. | |||||
| 2010-10-28 | * Handle out of memory condition. | Eelco Dolstra | 5 | -10/+28 | |
| 2010-10-26 | * Install config.h. | Eelco Dolstra | 1 | -0/+2 | |
| 2010-10-24 | * We need Bison 2.4 now. | Eelco Dolstra | 1 | -1/+2 | |
| 2010-10-24 | * When allocating an attribute set, reserve enough space for all | Eelco Dolstra | 4 | -28/+21 | |
| elements. This prevents the vector from having to resize itself. | |||||
| 2010-10-24 | * Keep attribute sets in sorted order to speed up attribute lookups. | Eelco Dolstra | 12 | -147/+185 | |
| * Simplify the representation of attributes in the AST. * Change the behaviour of listToAttrs() in case of duplicate names. | |||||
| 2010-10-24 | * Don't create thunks for variable lookups (if possible). This | Eelco Dolstra | 3 | -23/+60 | |
| significantly reduces the number of values allocated (e.g. from 8.7m to 4.9m for the Bittorrent test). | |||||
| 2010-10-24 | * Store attribute sets as a vector instead of a map (i.e. a red-black | Eelco Dolstra | 7 | -90/+129 | |
| tree). This saves a lot of memory. The vector should be sorted so that names can be looked up using binary search, but this is not the case yet. (Surprisingly, looking up attributes using linear search doesn't have a big impact on performance.) Memory consumption for $ nix-instantiate /etc/nixos/nixos/tests -A bittorrent.test --readonly-mode on x86_64-linux with GC enabled is now 185 MiB (compared to 946 MiB on the trunk). | |||||
| 2010-10-23 | * Fix compiling without Boehm. | Eelco Dolstra | 1 | -10/+8 | |
| * Fix the stats. | |||||
| 2010-10-23 | * Regression test for listToAttr's behaviour if an attribute name | Eelco Dolstra | 2 | -2/+3 | |
| occurs multiple times. | |||||
| 2010-10-23 | * Optimise string constants by putting them in the symbol table. | Eelco Dolstra | 4 | -39/+55 | |
| 2010-10-23 | * Make Value smaller by not storing redundant PrimOp info. | Eelco Dolstra | 2 | -25/+44 | |
| * Clear pointers in Values after overwriting them to make sure that no objects are kept alive unnecessarily. | |||||
| 2010-10-23 | * Remove allocValues(). | Eelco Dolstra | 4 | -36/+14 | |
| 2010-10-22 | * In environments, store pointers to values rather than values. This | Eelco Dolstra | 2 | -35/+25 | |
| improves GC effectiveness a bit more (because a live value doesn't keep other values in the environment plus the parent environments alive), and removes the need for copy nodes. | |||||
| 2010-10-22 | * Regression test for __overrides. | Eelco Dolstra | 2 | -0/+10 | |
| 2010-10-22 | * Store Value nodes outside of attribute sets. I.e., Attr now stores | Eelco Dolstra | 15 | -130/+150 | |
| a pointer to a Value, rather than the Value directly. This improves the effectiveness of garbage collection a lot: if the Value is stored inside the set directly, then any live pointer to the Value causes all other attributes in the set to be live as well. | |||||
| 2010-10-22 | * Make building against the Boehm GC a configure option. | Eelco Dolstra | 6 | -14/+42 | |
| 2010-10-20 | * Keep some more stats. | Eelco Dolstra | 2 | -0/+12 | |
| 2010-10-20 | * Use the Boehm garbage collector to reclaim unused memory in the Nix | Eelco Dolstra | 5 | -15/+29 | |
| expression evaluator. | |||||
| 2010-10-20 | * Evaluator garbage collection branch. | Eelco Dolstra | 0 | -0/+0 | |
| 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. | |||||
| 2010-10-06 | nix manual: fix 'install' -> 'uninstall' in garbage collection section of ↵ | Rob Vermaas | 1 | -1/+1 | |
| introduction | |||||
| 2010-10-04 | * In the referrers test, lower the nesting depth from 2500 to 1000 to | Eelco Dolstra | 1 | -1/+1 | |
| prevent hitting a stack overflow bug in the garbage collector. | |||||
| 2010-10-04 | * Make sure that config.h is included before the system headers, | Eelco Dolstra | 12 | -29/+29 | |
| 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. | |||||
| 2010-10-04 | * If std::tr1::unordered_set is unavailable, use std::set. | Eelco Dolstra | 2 | -0/+16 | |
| 2010-10-04 | * "type -P" isn't portable. | Eelco Dolstra | 1 | -1/+1 | |
| 2010-10-04 | * Don't use SSH's `-tt' flag because it doesn't seem to work | Eelco Dolstra | 1 | -6/+10 | |
| on OpenSolaris when using connection sharing. Instead have the remote side check for disconnection and kill the process group when that happens. | |||||
