• NET
  • TWebFile
    • Several pptimizations in TWebFile improving performance especially for TTree::Map() by about 35%. This has been achieved with a better caching strategy for request strings (especially avoiding to recalculate the auth base64 encoding), and with a drastic optimization in reading the response headers.
    • Fixes in the counting of the bytes read.
  • TWebSystem
    • New implementation of TSystem allowing to use TSystem::AccessPathName() and GetPathInfo() to check if a web file exists and to get its size. Directory browsing is not available yet.
• NETX
  • TXNetFile
    • Several fixes and optimisations, mainly in the use of the cache
    • Fix an offset issue affecting the use of the cache with files in archives
  • TXNetSystem
    • A few optimizations in the use of retry mechanism, path locality checks, file online checks.
      
• XROOTD
  • Import a new version of XROOTD (20091202-0509)
    • Fixes in bulk prepare and sync readv operations
    • Add support for 'make install' / 'make uninstall' and other improvements in configure.classic
    • Several improvements / fixes:
      • reduced memory and CPU consumption;
      • extreme cp optimizations;
      • windows porting
      • new cache policies on the client side
      • new listing features implemented recently in the 'cns' module.
      • optimizations in cmsd and cnsd (performance improvements)
      • support for openssl 1.0.0 (required by Fedora 12)
    • Support for if/else if/else/fi constructs
    • Several portability fixes
      • Support 32-bit builds with icc on 64-bit platforms
      • Improved detection of libreadline and lib(n)curses
  • Increase the flexibility for configuring with an external xrootd
    • Add standard switches to disentangle lib and inc dirs
            --with-xrootd-incdir=<path_to dir_containing_XrdVersion.hh>
            --with-xrootd-libdir=<path_to_dir_containing_xrootd_plugins_and_libs>
    • When passing a global xrootd dir with --with-xrootd, check both src/XrdVersion.hh and include/xrootd/XrdVersion.hh so that both build and install distributions are supported
  • Fix a problem with the xrootd build when running make via 'sudo' (issue #47644)
