* bug#63300: 29.0.90; Tramp keeps customizing variables on every connection @ 2023-05-05 10:42 Jimmy Yuen Ho Wong 2023-06-04 8:59 ` Michael Albinus 0 siblings, 1 reply; 17+ messages in thread From: Jimmy Yuen Ho Wong @ 2023-05-05 10:42 UTC (permalink / raw) To: 63300 Whenever I install a package or do anything that turns on Tramp such as sudoing, Tramp writes to my `custom-file-path` the variables `connection-local-criteria-alist` and `connection-local-profile-alist`. This is undesirable as it prevents the customs files from being versioned effectively and shared across multiple Emacs installations across machines. Furthermore, no package should write to the customs file without the user's explicitly approval. Defcustoms should be used for customizations, not caching.

In the past, connection-local-*-alist were simple variables. Then they have been converted to user options, see etc/NEWS: --8<---------------cut here---------------start------------->8--- *** Some connection-local variables are now user options. The variables 'connection-local-profile-alist' and 'connection-local-criteria-alist' are now user options, in order to make it more convenient to inspect and modify them. --8<---------------cut here---------------end--------------->8--- And that's the reason behind. I won't call the Tramp settings "hacked connection local alist variables". They are useful defaults. Best regards, Michael. ^ permalink raw reply [flat|nested] 17+ messages in thread

This is just too much surprises. Again, I think if tramp needs to cache the values of these variables, they should be written to a file in user-emacs-directory, not hacked in a customizable variable.

But these Tramp settings are connection-local, meaning they are different for different remote hosts. Connection-local variables have been invented for exact this purpose.

This property is normally set by customize when it is saved to the custom file. Something in Tramp is setting this property without saving the variable values to the custom file or going through customize. In fact, you can see it via M-x customize-option connection-local-criteria-alist. The value will be shown as SAVED. In addition, setting `enable-connection-local-variables` to nil early in early-init.el has no effect, the variable is still set on load. Both of this behavior violate what is documented in the docstring and https://www.gnu.org/software/emacs/manual/html_node/elisp/Standard-Properties.html. If you must, enable-conneciton-local-variables should be respected, and if you must, set the theme-value property on these connection-local variables instead of saved-value so custom-save-all will not save them.

If it works, I don't mind, although the solution looks more complicated (thus more risky during a pretest).

No further comments, so I've pushed the change to the emacs-29 branch. Closing the bug. > In general, Lisp programs should not modify values of user options, > that is only for the user. I agree, but here we have the case, that two complex variables have been transformed into user options in order to offer more convenient ways to modify them. So we must handle both cases, modification by other packages due to call of connection-local-set-profiles or connection-local-set-profile-variables, and modification in the customization buffer.

This is a different game. enable-connection-local-variables has no effect on setting / saving connection-local-criteria-alist and connection-local-profile-alist. e-c-l-v is used only in hack-connection-local-variables in order to control, whether connection-local variables shall be set as buffer-local variables.

No. > If you must, enable-conneciton-local-variables should be respected, > and if you must, set the theme-value property on these > connection-local variables instead of saved-value so custom-save-all > will not save them. No. In connection-local-set-profiles and connection-local-set-profile-variables it should be checked, whether the saved-value property is set. If not, it shall be reset to nil, after custom-set-variables has been called. The appended patch shall do the trick. Could you, please, test? Best regards, Michael.
