I am afraid, more serious refactoring is required to reuse result of `buffer-base-buffer', for the previous attempt to avoid issues with `buffer-file-name' see satotake to emacs-orgmode… [PATCH] org-refile.el: Fix the case of *scratch* buffer. Sat, 15 May 2021 19:38:39 +0900. https://list.orgmode.org/20210515103839.8574-2-doublequotation@gmail.com There are several corner cases with `org-refile-cache', `org-goto', and buffers. - Perhaps buffer name, not file name should be used as the cache key if some buffer is not associated with any file. Alternatively cache should not be used at all. - When an indirect buffer is narrowed down to some region (e.g. created using `org-tree-to-indirect-buffer') jump targets should be filtered to the displayed range. So the change is an improvement (I would prefer `and' instead of `when' in such expression, but it does not really matter). Leaving aside other issues and more serious refactoring, it seems, storing results to the cache requires a similar fix, so perhaps it is possible to move "(setq f ...)" code above of "(or ...)" and reuse f as the cache key. Please, send patches produced by "git format-patch" command.

Yes, and it would be instant (assuming (org-refile-get-targets) has been run in the original buffer). This is because the code path from org-goto has an overriding local binding of org-refile-targets to `((nil . (:maxlevel . ,org-goto-max-level)) before calling org-refile-get-location which calls org-refile-get-targets. > >> - org-goto in the original buffer takes no effort >> - but, org-goto in the indirect buffer takes time, which is unexpected. > >> diff --git a/lisp/org-refile.el b/lisp/org-refile.el >> index 16cff25bd..7189ef595 100644 >> --- a/lisp/org-refile.el >> +++ b/lisp/org-refile.el >> @@ -306,7 +306,10 @@ converted to a headline before refiling." >> (dolist (f files) >> (with-current-buffer (if (bufferp f) f (org-get-agenda-file-buffer f)) >> (or >> - (setq tgs (org-refile-cache-get (buffer-file-name) descre)) >> + (setq tgs (org-refile-cache-get >> + (buffer-file-name (when (bufferp f) >> + (buffer-base-buffer f))) >> + descre)) > > Thank you for the attempt to improve handling of indirect buffers. > > I am afraid, more serious refactoring is required to reuse result of > `buffer-base-buffer', for the previous attempt to avoid issues with > `buffer-file-name' see > satotake to emacs-orgmode… [PATCH] org-refile.el: Fix the case of > *scratch* buffer.

If buffer name is the key, that will mean a buffer and its indirect clone will generate two caches, which duplicates the work, no? > - When an indirect buffer is narrowed down to some region > (e.g. created using `org-tree-to-indirect-buffer') jump targets > should be filtered to the displayed range. > > So the change is an improvement (I would prefer `and' instead of > `when' in such expression, but it does not really matter).

I did use (ma)git-format-patch, but had some difficulty of getting gnus to send the formatted patch (I basically visited the patch file and ran (message-mode), but it was missing a few header fields compared to composing a new mail from gnus, so I manually copied over these fields). This was why I sent two emails. The first one[1] had an odd extra bit of Message-ID at the bottom of the message. Is this the one you were referring to as not being "standard", or is the other one[2] also not quite right?

My hypothesis is that if refile targets are requested from an indirect buffer at first then next attempt from the base buffer causes recalculation because of previous result is not properly stored. The code at the end of the function requires a similar fix. >>> diff --git a/lisp/org-refile.el b/lisp/org-refile.el >>> index 16cff25bd..7189ef595 100644 >>> --- a/lisp/org-refile.el >>> +++ b/lisp/org-refile.el >>> @@ -306,7 +306,10 @@ converted to a headline before refiling." >>> (dolist (f files) >>> (with-current-buffer (if (bufferp f) f (org-get-agenda-file-buffer f)) >>> (or >>> - (setq tgs (org-refile-cache-get (buffer-file-name) descre)) >>> + (setq tgs (org-refile-cache-get >>> + (buffer-file-name (when (bufferp f) >>> + (buffer-base-buffer f))) >>> + descre)) >> >> Thank you for the attempt to improve handling of indirect buffers. >> >> I am afraid, more serious refactoring is required to reuse result of >> `buffer-base-buffer', for the previous attempt to avoid issues with >> `buffer-file-name' see >> satotake to emacs-orgmode… [PATCH] org-refile.el: Fix the case of >> *scratch* buffer.

Certainly if a buffer has its base buffer then file name associated with the base buffer should be tried at first. However besides indirect buffers, buffers not associated with any files at all may exist. I am not sure that using buffer name is a good idea for them since temporary buffers may be discarded and new ones with same names may be created. My point is that refile targets for temporary buffers should not be cached at all or buffer name should be used as the key. Behavior should be deterministic. I do not request such change from you, but maybe it is just an additional couple of lines at the location you are changing anyway. >> So the change is an improvement (I would prefer `and' instead of >> `when' in such expression, but it does not really matter).

No, I missed commit message in the expected format https://orgmode.org/worg/org-contribute.html#commit-messages Just send the patch as an attachment.
