TRAMP not saving files the first time?

TRAMP not saving files the first time?

[Martin Kjær Jørgensen]

Hello,

I'm a happy Emacs 29.4 + TRAMP 2.7.1.2 user that usually edits text reliably
on my local system.

I have noticed weird behaviour when editing remotely using TRAMP+SSH. When
editing configuration text files on a remote server using TRAMP+SSH I
sometimes have to save the text file twice in order for the server to get the
changes. Saving the buffer once makes Emacs thinks its saved, but `cat' -ing
the file on the server afterwards shows nothing new is saved. If I then have
Emacs make a slight change, like adding a white space and delete it again, and
save again, the changes becomes visible on the server.

Have any of you seen similar behaviour, or maybe have ideas how to debug it?

I haven't seen this. However, I recommend to set tramp-verbose to 6, and
rerun your test. Once you see the problem (Tramp doesn't save for the
first time), copy the Tramp debug buffer. Send it, with a precise
explanation what you have done.

If the buffer is too large, or if the buffer might contain sensible data
you like to hide, send the message directly to me.
