The content was unrecoverable with "undo". Have you seen this before? The .org file before content corruption was about 1.5MB. GNU Emacs 26.3 macOS 10.15.7 Please let me know if I can provide more info.

Check to see if you have a backup of the file: Emacs, by default, will copy the original contents to filename~, i.e. adding a ~ to the end of the file name.

This incident sounds similar: https://emacs.stackexchange.com/questions/44659/help-emacs-empty-my-1-year-org-file I have some wild theories, including a gamma particle hitting my laptop ;) But: I do not know what emacs does under the hood in the org mode. For instance, the text below my cursor at the time of accident was about 1MB. As you type in org mode, the text below the cursor would have to be "shifted down". Maybe there is something in that operation, combined with the fact that the amount of text was relatively large... like I said, just some wild theories. Anyways, I hope that nobody else experiences this, and if they do, then we would be able to collect bug reports and figure out a fix.

I mean, if I visit plain text files, I guess it does not matter which mode I invoke, right? About git -- totally. It's just that unexplained bugs add to the paranoia feeling. By the way, I have started to test my theory that the bug has to do with the file size, but so far I have not been able to reproduce the bug. / Dmitry On Mon, Feb 15, 2021 at 12:36 PM Eric S Fraga <e.fraga@ucl.ac.uk> wrote: > On Friday, 12 Feb 2021 at 11:29, Dmitry Knyaginin wrote: > > I have some wild theories, including a gamma particle hitting my laptop > ;) > > Something I saw on the emacs developer list: if you invoke a special > mode while visting a file not intended for that mode, it is possible for > contents to be deleted and no undo information kept.

Another guess about your case: I have experienced deleted parts of buffer and lost history when using undo-tree. Do you happen to use it?

There are some modes that expect buffers to have specific content (e.g. think dired-mode or gnus-summary-mode etc.) and it may be that *some* may inadvertently throw away anything that doesn't fit their world view... These are modes that will typically be invoked by another command, not by the user directly. As I said, it was a throwaway comment I saw on the Emacs developer list. -- : Eric S Fraga via Emacs 28.0.50, Org release_9.4.4-213-g49364f ^ permalink raw reply [flat|nested] 8+ messages in thread
