This patch fixes a bug in which org-publish makes the following call...
(let ((org-inhibit-startup t) (org-mode)))
...in buffers that are already open. This often happens, for instance,
when publishing a sitemap. But there is no need to call org-mode again
in these open buffers. Moreover calling org-mode with
org-inhibit-startup set to t destroys crucial information in open
buffers, such as dir-locals variables. This can interfere rather
seriously with web publishing, causing website files I am editing to
lose the following crucial settings after I call org-publish:
((org-mode .
((org-link-file-path-type . relative)
(org-display-custom-times . t))))
Thanks,
Matt

Subject: [PATCH] Remove unnecessary invocations of org-mode
* lisp/ox-publish.el: (org-publish-find-title) (org-publish-find-date)
Fix unnecessary invocations of org-mode with
org-inhibit-startup.
The functions above call org-mode with org-inhibit-startup in org
buffers that are already open. The result is that these open buffers
lose some crucial local variables during publishing. For instance,
an open buffer will lose its dir-local-variables-alist setting
during publishing. There is no need to call org-mode here, because
org-mode is a) either already initialized in the buffer or b)
initialized via earlier call to find-file-no-select.
This looks to me like a relic of some past time when these functions were
called in temporary buffers that contained copies of the file's contents.

Oops... I see now that org-publish-find-date and org-publish-find-title
call org-export-get-environment. This in turn relies on org-set-local to
set #+BIND: variables, which requires the buffer to be writable. I have
an org-mode-hook that sets some of my web publishing files read-only (so
as to prevent accidental editing). Without org-inhibit-startup, these
buffers remain read-only, causing the following error message:
--8<---------------cut here---------------start------------->8---
org-export--get-global-options: Buffer is read-only: #<killed buffer>
--8<---------------cut here---------------end--------------->8---
This could be solved by wrapping org-export-get-environment withing
those functions with (let ((buffer-read-only nil)) ...).
However, I think the fundamental problem is that
org-export-get-environment should be called on a copy of the buffer.
That, at least, is how it is used in org-export-as (see lines 3084 -
3107 of ox.el). When org-publish-find-title and org-publish-call-date
calls it in a buffer that is already open, it does so on the original
copy of the buffer. This has the effect of setting the #+BIND variables
within the live buffer, which could (theoretically) be dangerous, since,
AFAICT, they should only be set in a temporary copy of the buffer.
So to be safe, we could do the following in org-publish-find-date and
org-publish-find-title...
(org-export-with-buffer-copy (org-export-get-environment))
What do you think?
Best,
Matt

[...continuing the previous post.]
I think I've found a more general problem here. When called in an org
buffer...
(let ((org-inhibit-startup t)) (org-mode))
...either wipes out dir-locals variables or prevents them from loading.
I have looked at the org-mode code and am not entirely sure why this
would be the case.
However, this causes problems, for instance, when
org-agenda-inhibit-startup is t or when calling org-toggle-tags-groups.
And one more minor thing...
The documentation for org-agenda-inhibit-startup says that the default
is t. However, the default is nil.
,----
| Inhibit startup when preparing agenda buffers.
| When this variable is `t' (the default), the initialization of
| the Org agenda buffers is inhibited: e.g. the visibility state
| is not set, the tables are not re-aligned, etc.

Thanks,
Matt

Correction... this should be...
(let ((inhibit-read-only t)) ...)
Correction is for the record only, as this is moot given the rest of the
email.

Yes, this sounds right, please go ahead.
I applied your fix in the maint branch, so if you need to revert it
please do the revert from there first.

Here's the patch. There's no need to revert anything, as this builds

Please *do not apply* the previous patch. Instead, I've attached an
optimized version.
All in all this patch + commit 507244d56b055e7595ba94fe89d45c7ddb2559df
modestly improves the performance of org-publish-org-sitemap. On a
directory of 104 files, it used to take this long...
org-publish-org-sitemap 1 10.508871433 10.508871433
...to generate a sitemap. With this patch and commit 507244d, it takes
this long...
org-publish-org-sitemap 1 7.700290794 7.700290794
Clearly, this is still very inadequate, but it is an improvement. I
would love to use the built in site-map functions, but they are simply
to slow for any larger projects.
Could we do something like this to speed it up?
--8<---------------cut here---------------start------------->8---
(with-temp-buffer
(insert-file-contents file)
(goto-char (point-min))
(when (re-search-forward "^#\\+TITLE:" nil t)
(org-element-at-point)))
--8<---------------cut here---------------end--------------->8---
Until then, here's the patch.

I guess so. But I'm in a rush and can't really check carefully.
In the meantime, thanks for the recent patches!

No, you also need to parse #+SETUPFILE: keywords. You could also get
false positive within a verbatim block:
#+begin_example
#+title: something
#+end_example
However, it is possible to write a specialized function to extract
only #+TITLE.
Another option is to cache results. See `org-publish-cache-set' and
`org-publish-cache-get'.

Thanks for the helpful information. I think the cache would be a nice
way to go, especially if it were combined a timestamp check. E.g., only
files that have been updated since the last publishing should be queried
for titles; otherwise, use the cached file.
I notice that org-publish-find-title does cache the title, but AFAICT
this is never used, since org-publish-format-file-entry calls
org-publish-find-title with the reset argument. Perhaps we could add a
variable to make this optional in org-publish-format-file-entry. E.g.,
--8<---------------cut here---------------start------------->8---
(defun org-publish-format-file-entry (fmt file project-plist)
(format-spec
fmt
`((?t . ,(org-publish-find-title file org-publish-find-title-use-cache))
[...]
--8<---------------cut here---------------end--------------->8---
A similar option could be added to the date function date function.
Would it be O.K. if I went ahead and implemented this?
Thanks,
Matt

Unfortunately, in the following (unexpected) setup
== a.org ==
#+SETUPFILE: b.org
== b.org ==
#+TITLE: Something
modifying "b.org" changes title for "a.org", even though the latter is
not modified. A dag would be needed to handle this case.
The same goes for #+INCLUDE keywords.
Overkill, IMO.

Fine by me. I suggest to mention previous caveat in the docstring.
