HashSumValue::Set: Do not provide const char* overload 2016-01-08T20:20:25Z Julian Andres Klode jak@debian.org 2016-01-08T20:19:32Z urn:sha1:af4899c9df6e925b1cb099c29bd78788b2984cca Hide the std::string overload instead of providing a const char * one, the old variant was stupid. Gbp-Dch: ignore operator==(char*, StringView) use StringView.operator== 2016-01-08T01:33:36Z Julian Andres Klode jak@debian.org 2016-01-08T01:32:23Z urn:sha1:0cc8987abf9f25c458833a0479bc4cb11b405e16 Use the same path for both comparisons, as the operator== path is faster than just calling compare() - it avoids any comparison if the size differs. Gbp-Dch: ignore StringView: rfind: pos should be end of substr, not start 2016-01-07T19:23:48Z Julian Andres Klode jak@debian.org 2016-01-07T19:23:48Z urn:sha1:0e58689ae76e8155bc1f418323aa9e56c34187f6 Gbp-Dch: ignore StringView: pos argument default should be npos 2016-01-07T19:21:16Z Julian Andres Klode jak@debian.org 2016-01-07T19:21:16Z urn:sha1:eee8ee176a5ae3377cc601eb68cdb576b8076761 Gbp-Dch: ignore StringView::rfind(): Call rfind() instead of find() on subst 2016-01-07T19:01:16Z Julian Andres Klode jak@debian.org 2016-01-07T19:01:16Z urn:sha1:8cfd5495e30533e2ab708c8dc875f1c6f29650fd Thanks: Niels Thykier for reporting on IRC Gbp-Dch: ignore Switch performance critical code to use APT::StringView 2016-01-07T18:59:08Z Julian Andres Klode jak@debian.org 2016-01-07T18:16:23Z urn:sha1:eff0c22e59e65b6b63e854ff41eb091278e05714 This improves performance of the cache generation on my ARM platform (4x Cortex A15) by about 10% to 20% from 2.35-2.50 to 2.1 seconds. Introduce internal APT::StringView class 2016-01-07T18:59:08Z Julian Andres Klode jak@debian.org 2016-01-07T18:14:21Z urn:sha1:fe7fa47c1141066c89ab3382c318a4b9d00fe249 The class APT::StringView implements a drop-in replacement for a subset of C++17 std::string_view() features. It will be dropped at a later point and may not be used in public interfaces. CopyFile: Use 64 * 1024 instead of 64000 as buffer size 2016-01-07T15:17:51Z Julian Andres Klode jak@debian.org 2016-01-07T15:16:06Z urn:sha1:40940e63a4dd3c7ef09ea1175e189350457b7270 This is a multiple of the page size and thus results in less page faults, speeding up copying. Also, while we're at at, unify all uses of that size in a constant variable APT_BUFFER_SIZE. FileFd: (native) LZ4 support 2016-01-07T13:28:27Z Julian Andres Klode jak@debian.org 2015-12-27T23:07:03Z urn:sha1:e3fbd54cee3fffecbf4f7c384e0aad715fc68218 Implement native support for LZ4 compression, using the official lz4 library.
