* Remove dead entries in .ninja_log and .ninja_deps while recompacting.Nico Weber2014-01-021-3/+12
| | | | | | | | | | For .ninja_deps, remove objects that have no in-edges or whose in-edges do not have a "deps" attribute. (This matches the behaviour of `-t deps`). BuildLog doesn't know about state, so let its recompact method take delegate that decides is a path is life or not, and implement it in NinjaMain.

* Revert "Make StringPiece data members private."Nico Weber2012-07-281-2/+2
| | | | | | This reverts commit 904c9610fe66c4f4bd63a07d6f057c8603d24394. The commit caused issue #380, this revert fixes it. The revert also makes the test from the previous commit pass.

* switch build log to print hashes as hexEvan Martin2012-06-191-2/+2
| | | | | | Nico convinced me that it's safe to do this without revving the build log format: the old decimal values will still parse as hex (just as different numbers) and cause a superfluous rebuild.
* drop support of log formats < 4Evan Martin2012-06-181-10/+15
| | | | | Log format 4 was introduced in January. There's been plenty of time to migrate.

* Only store command hashes in the build log.Nico Weber2012-06-151-5/+59
| | | | | | | | | | | | | | .build_log load time 350ms -> 17ms, filesize 197MB -> 1.6MB on Mac. On Windows, it's 500ms -> 20ms. Makes the build log a lot less useful for scripts, but there could be a tool for use cases that need log information. A prototype of such a tool is in https://github.com/nico/ninja/commit/1b243d311 The hash function is 64bit murmurhash2. Assuming that that different commands get the same hash only by chance, it's is very unlikely for two different commands to hash to the same value with a 64bit hash.
* Switch LineReader from fgets() to just fread().Nico Weber2012-05-101-5/+33
| | | | | | | | | | | | | | | | | | | | | fgets() needs to search for a \n in the input, and LineReader's strstr() did the same work again. By using fread() directly, this duplicate work can be saved. (I tried using readline() / fgetln() for the same saving, but those functions are not standard, and were slower than the code in this CL.) Results from running build_log_perftest, on OS X: Before: min 369ms max 372ms avg 370.4ms After: min 243ms max 247ms avg 244.8ms On Windows: Before: min 796ms max 904ms avg 858.0ms After: min 359ms max 375ms avg 371.4ms On Linux: Before: min 161ms max 169ms avg 164.8ms Before: min 130ms max 137ms avg 132.6ms

* BuildLog: Use Log::insert(Log::value_type()) to avoid invalid strings.Evan Jones2012-01-131-2/+2
| | | | | | | The MSVC std::string implementation copies strings, so using make_pair resulted in a pointer to invalid memory. This ensures the insert uses a StringPiece without an intermediate std::string copy, so the correct pointer ends up in the hash_map.

* Protect BuildLog data member variables by making them private.Thiago Farina2011-12-201-2/+6
| | | | | | | | | They are not accessed outside of BuildLog and there is even a SetConfig function to set the |config_| variable. So better to make them private to BuildLog now while nobody is using it outside. Signed-off-by: Thiago Farina <tfarina@chromium.org>

|\ | | | | CMake requirements: Make-style order-only dependencies, restat rules
| * Implement restat rulesPeter Collingbourne2011-10-241-10/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A restat rule is a rule which is capable of pruning the build tree depending on the timestamps of its outputs before and after a build. After a restat rule is rebuilt, Ninja will re-stat each output file to obtain its current timestamp. If the timestamp is unchanged from when Ninja initially stat'ed the file before starting the build, Ninja will mark that output file as clean, and recursively for each reverse dependency of the output file, recompute its dirty status. Ninja then stores the most recent timestamp of any input file in the build log entry associated with the output file. This timestamp will be treated by future invocations of Ninja as the output file's modification time instead of the output file's actual modification time for the purpose of deciding whether it is dirty (but not whether its reverse dependencies are dirty).
