nzbget 20.0-testing-r2147

Post by hugbug » 29 Oct 2017, 20:54

Changes since 20.0-testing-r2108
  • massive performance optimisations in downloader (#448):
    • improved CRC32 calculation (#446);
    • improved yEnc decoder (#450);
    • processing data in one pass;
    • SIMD implementation of decoder and CRC functions on x86 and ARM CPUs; SIMD code relies on node-yencode library by Anime Tosho (#454);
    • overall performance improvement up to +500% on x86 and +250% on ARM (better speed or less CPU usage);
    • for details see Benchmarks);
  • using glibc instead of uClibc in universal installer builds for Linux (#459):
    • this significantly improves performance (see benchmarks above);
    • compatibility with Android and other systems is hopefully also improved;
    • in universal installer glibc is used on x86 and ARM;
    • uClibc is still used on MIPS and PPC;
  • new option "SkipWrite" for easier speed tests;
  • enhancements in NServ:
  • memory cache to reduce disk load during speed tests - new command line switch “-m” (#448);
  • speed control - new command line switches “-w“ and “-r” (#451);
  • fixed: example pp-scripts may not work properly if nzbget password or username contained special characters (#452, #453);
  • changed default location of log-file (#455);
  • better handling of broken connections (#460);
  • removed obsolete or less useful options "SaveQueue", "ReloadQueue", "TerminateTimeout", "AccurateRate", "BrokenLog" (#461);
  • renamed option "LogBufferSize" to "LogBuffer" (#461);
  • fixed: backup servers not used on certain article decoding errors (#462).

Other changes since 19.1
  • performance optimisations in web-interface (#421):
    • reduced number of requests when loading webui by combining all javascript-files into one and all css-files into one;
    • reduced load time by calling multiple API-methods simultaneously;
    • extensive use of browser caching for static files significantly reduces the amount of data transferred on webui initialisation;
    • extensive use of browser caching for API requests reduces the amount of data transferred during webui status updates, especially when nzbget is in idle state and there are no changes in download queue or history;
    • avoid work in browser on status updates if there are no changes in download queue or history;
    • support for keep alive connections significantly reduces overhead for establishing connections on webui status updates, especially when connecting to nzbget via TLS/SSL (avoiding TLS handshakes);
  • a number of performance optimisations for large download queue with thousands of items (#438):
    • much faster loading of queue from disk greatly improves program start up time;
    • improved queue management for faster download speed;
  • now offering 64 bit binaries for Windows (#435):
    • installer includes 32 and 64 bit nzbget binaries;
    • when updating from older versions the 64 bit binary is installed automatically, although into the old location to keep all your shortcuts intact;
    • using word "windows" instead of "win32" in the setup file name;
  • automatic update check (#440):
    • new option "UpdateCheck" to check for stable or testing versions (or disable);
    • when a new version is found a notification is shown;
    • the update check is enabled by default for stable versions;
  • added support for Unix domain sockets (POSIX only) (#400);
  • better error handling when fetching rss feeds (#416);
  • updated POSIX build files to newer autotools version (#418):
    • compatibility with newer autotools;
    • compatibility with newer platforms such as aarch64;
  • enabled functional tests on Travis CI (#443);
  • better username/password validation when testing connection on settings page (#433);
  • improved rar-renamer to better handle certain cases (#442);
  • support for redirect codes 303, 307 and 308 in web-client for fetching of rss feeds and nzb-files (#420);
  • installer for FreeBSD is now built using Clang instead of GCC; this fixes incompatibility with FreeBSD 11 (#425):
  • universal Linux installer can now be used on FreeBSD (via Linux compatibility mode) (#423);
  • updated unrar to v5.50;
