gh-138122: Add differential flame graph ( #145785 )
...
Differential flame graphs compare two profiling runs and highlight where
performance has changed. This makes it easier to detect regressions
introduced by code changes and to verify that optimizations have the
intended effect.
The visualization renders the current profile with frame widths
representing current time consumption. Color is then applied to show the
difference relative to the baseline profile: red gradients indicate
regressions, while blue gradients indicate improvements.
Some call paths may disappear entirely between profiles. These are
referred to as elided stacks and occur when optimizations remove code
paths or when certain branches stop executing. When elided stacks are
present, an "Elided" toggle is displayed, allowing the user to switch
between the main differential view and a view showing only the removed
paths.

gh-138577: Fix keyboard shortcuts in getpass with echo_char ( #141597 )
...
When using getpass.getpass(echo_char='*'), keyboard shortcuts like
Ctrl+U (kill line), Ctrl+W (erase word), and Ctrl+V (literal next)
now work correctly by reading the terminal's control character
settings and processing them in non-canonical mode.
