* lisp/org-persist.el: Bind pp-use-max-width to silence byte-compiler
warning about unused lexical variable.
Note that loading pp.el upfront rather than relying on the pp function
being autoloaded would also eliminate the warning, but that would only
work on Emacs 29 or later because earlier versions do not have the
pp-use-max-width option.
* lisp/org-persist.el (org-persist--write-elisp-file,
org-persist--read-elisp-file): Instead of letting `find-auto-coding' be
invoked to determine the coding for org-persist cache files (which can
be surprisingly expensive), we simply set utf-8 coding when
reading/writing.
* lisp/org-persist.el (org-persist--write-elisp-file): For the reasons
mentioned in the large code comment, it simply does not make much sense
to use fsync when writing cache files.
The value of fsync in general on modern hardware seems questionable,
particularly with CoW filesystems which take care of the problem better
than it seems fsync ever could.
* lisp/org-persist.el (org-persist-unregister): Do not try to
normalize 'all ASSOCIATED. It is not a valid association that should
be handled specially. Previously, an error was thrown.
* lisp/org-persist.el (org-persist-unregister): Add new optional key
:remove-related to remove all the containers stored alongside with
CONTAINER in addition to CONTAINER itself. Update to docstring.
* lisp/org-persist.el (org-persist-register): Document that MISC must
be a plist.
(org-persist--get-collection): Throw an error when MISC is not a
plist. Fix arglist - MISC is now passed explicitly as a single
object.
(org-persist--storage-version): Bump version to avoid obsolete
malformed containers with improperly included MISC.
* lisp/org-persist.el (org-persist--normalize-container): Recognize
new `elisp-data' container. Treat raw strings, keywords, and quoted
expressions as `elisp-data' container options.
(org-persist-read:elisp-data):
(org-persist-load:elisp-data):
(org-persist-write:elisp-data):
(org-persist-gc:elisp-data):
(org-persist-associated-files:elisp-data): New functions.
(org-persist-read): Simplify docstring example using `elisp-data'
container.
Also, update examples in top comment.
* lisp/org-persist.el (org-persist-version): Bump version.
(org-persist-index-file): Use .eld extension by default.
(org-persist--index): Set mode in buffer-local variable line.
* lisp/org-persist.el (org-persist-read): Only return the requested
containers. Add new optional keyword argument :read-related to read
the containers stored together with requested. Update the docstring
accordingly.
(org-persist-load): Update definition according to `org-persist-read'.
* lisp/org.el (org-mode): Explicitly load all the associated
cache variables.
* lisp/org-persist.el (org-persist-read:index): Allow setting where
the elisp container value is taken from: locally, from buffer, or from
a global variable.
* lisp/org-persist.el: Create `org-persist-directory' early, when we
decide the directory name. This way, even if third party code gets to
know the directory name in /tmp, it cannot raise file permissions by
creating `org-persist-directory' with loose access rights ahead of us.
Also, create and set `org-persist-directory' before we check if have
have proper access rights to write to it.
(org-persist-write-all): Do better job clearing
`org-persist-directory' if nothing is going to be written inside.
(org-persist-clear-storage-maybe): New function to be called before
exiting Emacs. It is used to remove the persistent data before
exiting. Multi-session persistence is not and must not be needed when
calling Emacs with -Q command line argument. Call the function before
exiting Emacs in `kill-emacs-hook'.

Remove the directory created by `make-temp-file' when Emacs is called
with -Q command line argument. Only use the return value as the
directory to be created when something is actually stored by
org-persist while running Emacs.

* lisp/org-persist.el (org-persist--disable-when-emacs-Q): Rename
`org-persist-disable-when-emacs-Q' to internal variable. Update the
docstring.
(org-persist-read):
(org-persist-write):
(org-persist-gc): Do not disable persistence. Persistence is
necessary for remote file caching to work within a single Emacs
session. Instead, use temporary directory as index for emacs -Q.
* lisp/org-persist.el (org-persist-write-all): Do not create
`org-persist-directory' when index does not contain any data except
index version.
Link: https://orgmode.org/list/875yedw0ib.fsf@localhost
* lisp/org-persist.el (org-persist-write, org-persist-load,
org-persist-write:index, org-persist-load:index): Check if the index
file has been externally updated since loading, and if so try to perform
basic merging of the current index file contents and the loaded index
before performing GC or overwriting the index file.
(org-persist--index-age, org-persist--merge-index-with-disk,
org-persist--merge-index): New variable and functions to keep track of
index age and perform merging.
* lisp/org-persist.el (org-persist-write:url): Since the url write
function is called as part of `org-persist-write-all', it is worth
adding a check to avoid re-downloading the file if a file already exists
in the expected location.
* lisp/org-persist.el (org-persist-associated-files:file): Add the
"container" argument used but omitted from the function declaration of
`org-persist-associated-files:file' in 534633d508.
* lisp/org-persist.el (org-persist-write:url): Since the url write
function is called as part of `org-persist-write-all', it is worth
adding a check to avoid re-downloading the file if a file already exists
in the expected location.
* lisp/org-persist.el (org-persist-gc, org-persist--remove-from-index,
org-persist-gc:file, org-persist-gc:url, org-persist-gc:version,
org-persist-gc:url, org-persist-associated-files:generic,
org-persist-associated-files:url, org-persist-associated-files:elisp,
org-persist-associated-files:index,
org-persist-associated-files:version,
org-persist-associated-files:file): Use associated files for GC, and
move the associated files functions into the public
namespace (i.e. remove the double dash).
* lisp/org-persist.el (org-persist-gc, org-persist--associated-files,
org-persist--associated-files:url): The url container stores downloaded
files separately within `org-persist-directory', which means that
`org-persist-gc' picks them up as "orphan files" and deletes them every
time it is called. To avoid this collateral damage, a new family of
collection-specific functions is introduced,
"org-persist--associated-files:COLLECTION". This allows collections to
tell GC about associated files that should be left alone, and is used
for url collections to preserve downloaded files.
* lisp/org-persist.el (org-persist-gc): The `org-persist-remote-files'
documentation states that when set to a number (n) it will keep that
many files. However, since a <= comparison is used with setting the
expired status of the files every remote file from n-th file onwards
/inclusive/ is marked as expired, and so only n-1 files were actually
kept. With a less-than operator, the behaviour will actually match the
docstring.
* lisp/org-persist.el (org-persist-gc): The :file association of URL
containers lead to `file-exists-p' being called on them, which always
returns nil, causing URL containers to always be garbage collected.
Since the :file entry doesn't really represent a filesystem object, we
now check if the container is url and if so prevent the :file
association from being used in gc checks.
