2014-06-23qapi/string-output-visitor: fix human outputHu Tao
"0x1-0x10" looks better than "0x1-10" Signed-off-by: Hu Tao <hutao@cn.fujitsu.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>
2014-06-19qapi/string-output-visitor: fix bugsMichael S. Tsirkin
in human mode, we are creating the string: 16-31 (16-31) instead of 16-17 (10-1f) because we forgot to pass 'true' as the human parameter on one of the two calls to format_string. Also, this is a worsening of quality; previously we would produce 16 (0x10) to make it obvious which number was hex. Fix these issues.

2014-06-19qapi: fix build on glib < 2.28Michael S. Tsirkin
The following commits: qapi: make string output visitor parse int list qapi: make string input visitor parse int list break with glib < 2.28 since they use the new g_list_free_full function. Open-code that to fix build on old systems. Cc: Hu Tao <hutao@cn.fujitsu.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

2014-02-14qapi: Refine human printing of sizesPaolo Bonzini
This fixes several bugs or shortcomings of the previous pretty-printer. In particular: * use PRIu64 instead of casting to long long * the exact value is included too * the correct unit of measure (MiB, GiB, etc.) is used. PiB and EiB are added too. * due to an off-by-one error, 512*2^30 was printed as 0.500MiB rather than 512MiB. floor(log2(val)) is equal to 63 - clz(val), while the code used 64. * The desired specification is %g rather than %f, which always uses three decimals in the current code. However %g would switch to scientific notation when the integer part is >= 1000 (e.g. 1000*2^30). To keep the code simple, switch to the higher power when the integer part is >= 1000; overflow is avoided by using frexp instead of clz.

2014-02-14qapi: Add human mode to StringOutputVisitorPaolo Bonzini
This will be used by "info qtree". For numbers it prints both the decimal and hex values. For sizes it rounds to the nearest power of 2^10. For strings, it puts quotes around the string and separates NULL and empty string.

2012-06-08qapi: String visitor, use %f representation for floatsMichael Roth
Currently string-output-visitor formats floats as %g, which is nice in that trailing 0's are automatically truncated, but otherwise this causes some issues: - it uses 6 significant figures instead of 6 decimal places, which means something like 155777.5 (which even has an exact floating point representation) will be rounded to 155778 when converted to a string. - output will be presented in scientific notation when the normalized form requires a 10^x multiplier. Not a huge deal, but arguably less readable for command-line arguments. - due to using scientific notation for numbers requiring more than 6 significant figures, instead of hard-defined decimal places, it fails a lot of the test-visitor-serialization unit tests for floats. Instead, let's just use %f, which is what the QJSON and the QMP visitors use. Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com> Signed-off-by: Andreas Färber <afaerber@suse.de>
2012-02-21qapi: add string-based visitorsPaolo Bonzini
String based visitors provide a consistent interface for parsing strings to C values, as well as consuming C values as strings. They will be used to parse command-line options. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
