gh-87820: IDLE: fix config disabling tab completion #26421
Conversation
This removes three key bindings from the key configuration mechanism, which are required to always be bound to specific keys for IDLE to behave properly: * '<<smart-backspace>>': ['<Key-BackSpace>'], * '<<newline-and-indent>>': ['<Key-Return>', '<Key-KP_Enter>'], * '<<smart-indent>>': ['<Key-Tab>'], Signed-off-by: Tal Einat <532281+taleinat@users.noreply.github.com>

The only function reason to keep these fixed keys separate from those that follow is that the pseudoevent -- handler bindings are done above for these and below for the existing fixed key keys. And this is related to where the handler are defined. So keep the separation for now.

These two are not relevant to tab completion. So it we do these together, I think we need to change the PR title (see my issue title revision) and reword this a bit.

I'm not sure the PR/commit title must describe all of the technical changes made. The additional change to the <<newline-and-indent>> and <<smart-backspace>> bindings has negligible significance to users, since even before this change, changing these bindings breaks IDLE rather badly.
Having this detail in the NEWS entry, and possibly in the body of the commit message, seems right to me.

To be clear, I now think that the existing PR title is good, since it describes the only significant bug being fixed.

Today I think the title is fine as is. The message that follows can say more.

The underlying issue causing tab-completion to be broken after using the config dialog: Two events are bound to
<Key-Tab>:<<smart-indent>>and<<autocomplete>>. The order these are bound is important: The binding to<<autocomplete>>must be done last so that it will be invoked first. The current bug is that<<smart-indent>>is unbound and then bound again by the config dialog, which changes the order and breaks tab-completion.This PR removes three key bindings from the key configuration mechanism, which are required to always be bound to specific keys for IDLE to behave properly:
I manually verified that having a
config-keys.cfgfile in.idlercwith those keys defined in it doesn't cause any issues after this change is made. (IdleConf.GetCoreKeys()is written in a way that ensures this.)
