I mentioned a number of issues with it in the mailing list thread
linked from the PR you made to disable it by default.
I don't think we should cram this in just because of string freeze,
especially with the open issues, the UI issues, and that we will be
releasing again in a few months. I'm not opposed to the feature, I'm
opposed to the implementation (re-using an existing feature to do
something else, something unexpected of the existing feature, as well
as the infobar without a checkbox that can be hidden from the user
without ever seeing it).

Carrying this discussion to the ML.
Can you elaborate on the issues you see?
Mostly the stuff I mentioned in the previous mailing list thread on
this subject. The semantics of the Reload feature have changed and no
longer does reload mean "drop everything about this file and load it
again" it means, "store another copy of this file in RAM and load it
again". I feel like it's not a good idea to re-use the File->Reload
feature like this, and under not uncommon scenarios, Geany is no
longer "lightweight" with respect to RAM usage.
Reload barely means "replace the buffer with the current file's
content", it's not connected to the undo history. And it still does that.
Semantically Reload should do exactly what Close and then Opening the
file again would do. We've changed the meaning of an existing feature to
do something different (replace text from current disk file).
You can disable that feature. What's your problem?
I don't think it should be enabled by default.
To give an example, if someone opened a big log file and Reloads it,
or if they have many files from version control open and switch
branches, every reload will "leak" the size of each document worth of
memory, making Geany use much more RAM than before. Scintilla's undo
mechanism just isn't designed to efficiently handle the case of the
entire document being replaced. The only workaround to regain all the
memory wasted by Geany is to close all the files and start over.
So you are concerned about very large files. I understand that. But
that's really an edge case, and I don't feel that everybody else should
suffer for edge cases. Especially not because Geany is an designed to be
an editor, not a very-large-file viewer.
Large files or many files. If someone has a huge project with many files
open and changes Git branches, then for each of the documents, each time
this is done, it will store a copy of the document in memory.
The various preferences are exactly for that, to make up for such edge
cases.
The change is the edge case, the existing behaviour which has been in
place for almost 10 years is the "normal" case. I agree this should be a
various preference (or an edit action), I just don't think it should be
enabled by default, changing the existing (common) meaning of Reload.
BTW, I think we only store the undo on reload if the file has actually
changed since it was opened. So for simply viewing dumps there shouldn't
be an increased memory footprint:
/* We only add an undo-reload action if the document
has actually changed.
* At the time of writing, this condition is moot
because sci_set_text
* generates an undo action even when the text hasn't
really changed, so
* actions_count is always greater than zero. In the
future this might change.
* It's arguable whether we should add an undo-reload
action unconditionally,
* especially since it's possible (if unlikely) that
there had only
* been "invisible" changes to the document, such as
changes in encoding and
* EOL mode, but for the time being that's how we roll. */
If that's the case, and we somehow tell if the file changed, then we
shouldn't be prompting the user or anything either.
I think the new preference is fine, I just don't think it ought to be
enabled by default, or else it ought to be associated with a new
(Edit, not File) action altogether as opposed to changing the
semantics of the existing feature as everyone is used to.
As to the UI. It's important that we get any UI for 1.26, therefore
we had to manage before string freeze. [...]
Why is it important to rush it in before 1.26? One of the points of
the accelerated release cycle is so that people would stop wanting to
cram stuff in right before release. It's only a few months until next
release, so there's no need to keep trying to rush in controversial
stuff.
The feature was targeted at 1.25 already. The feature itself hasn't
changed (you didn't do anything to optimize it either). We simply
created a UI to inform about it. It wasn't rushed either. The PR was
open for more than two weeks and was ignored.
I raised these same issues already, but I guess nobody remembers (except
the mailing list archive and Github comments). When I say rushed, I
refer to your comment "String freeze is tomorrow so please merge" and
the fact that I raised these issues on the PR and yet it was merged
before I even had a chance to respond to the comments added.
Cheers,
Matthew Brush
