progress: avoid ui.configbool() lookup when progress bar is active
Profiling revealed that the ui.configbool('progress', 'debug') during
progress bar updates was consuming a significant amount of overhead.
This commit adds an attribute on progress bar instances that caches
this config option.
The impact on `hg perfprogress` with default options is significant:
before: ! wall 4.641942 comb 4.580000 user 4.210000 sys 0.370000 (best of 3)
after: ! wall 1.948626 comb 1.950000 user 1.950000 sys 0.000000 (best of 5)
After this change, profiling reveals that progress.progbar.progress()
is now consuming ~73% of time.
This change does not improve the execution time if the progress bar
is disabled. We may want a more comprehensive solution for that case,
as the progress bar won't be enabled in a number of scenarios (e.g.
servers and processes not attached to an interactive TTY).
I also think that overhead of ~2.0s for 1M updates is a bit high.
I suspect further refactoring of the progress bar can significantly
reduce overhead. I don't have plans to do this, however.
