           Summary: Performance improvements in read_block()
           Product: XCB
           Version: 1.1
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: medium
         Component: Library
        AssignedTo: xcb at lists.freedesktop.org
        ReportedBy: markus.fleschutz at x-software.com
         QAContact: xcb at lists.freedesktop.org


in libxcb-1.5/src/xcb_in.c: read_block() should read: (replace the new ELSE by
else)

...
        if(ret > 0)
            done += ret;
        ELSE if(ret < 0 && errno == EAGAIN)
        {
...
        }
        ELSE if(ret <= 0)
             return ret;
...

This saves 2 if() on partial read.
