      perf report: Don't abbreviate file paths relative to the cwd · 361d1346
      由 Dave Martin 提交于 
      This avoids around some problems where the full path is executables and DSOs it
needed for finding debug symbols on platforms with separated debug symbol files
such as Ubuntu.  This is simpler than tracking an extra name for each image.

The only impact should be that paths in verbose output from the perf tools
become absolute, instead of relative to .

      perf ui: New hists tree widget · 0f0cbf7a
      由 Arnaldo Carvalho de Melo 提交于 
      The stock newt checkbox tree widget we were using was not really
suitable for hist entry + callchain browsing.

The problems with it were manifold:

- We needed to traverse the whole hist_entry rb_tree to add each entry +
  callchains beforehand.

- No control over the colors used for each row

So a new tree widget, based mostly on slang, was written.

It extends the ui_browser class already used for annotate to allow the
user to fold/unfold branches in the callchains tree, using extra fields
in the symbol_map class that is embedded in hist_entry and
callchain_node instances to store the folding state and when changing
this state calculates the number of rows that are produced when showing
a particular hist_entry instance.

This greatly speeds up browsing as we don't have to upfront touch all
the entries and only calculate callchain related operations when some
callchain branch is actually unfolded.

The memory footprint is also reduced as the data structure is not
duplicated, just some extra fields for controling callchain state and to
simplify the process of seeking thru entries (nr_rows, row_offset) were
added.

      perf ui: Show the scroll bar over the left window frame · 8d8c369f
      由 Arnaldo Carvalho de Melo 提交于 
      So that we gain two columns and look more like classical (at least in
TUIs) scroll bars bars.

      perf ui: Consider the refreshed dimensions in ui_browser__show · 63160f73
      由 Arnaldo Carvalho de Melo 提交于 
      When we call ui_browser__show we may have called
ui_browser__refresh_dimensions to check if the maximum lenght for the
contained entries changed, such as when zooming in and out DSOs or
threads in the hist browser.

For that to happen we must delete the old form, that will take care of
deleting the vertical scrollbar, etc, and then recreate them, with the
new dimensions.

      Will be used to figure out the window width needed in the new tree
widget.
