Hi, I have created a transactional library, and I am trying to make the vim :write command transactional. The idea here is that, instead of writing to the .swp file, vim directly applies updates to the relevant file. (I'm only guessing that this is how vim works when the noswpfile setting is enabled. Please correct me if I'm wrong.)
I've wrapped the do_write(eap) command in ex_write() (in src/ex_cmds.c) in a transaction. From my logs, it seems like some random file with a filename of 4 random digits (4913 in my case) was created. And then the original file was renamed to itself with a "~" at the end. And then a file is created with the original file's name, and then that's removed. In any case, it seems like the logs I record for filesystem operations do not reflect the final state of my folder. My question is, are there other commands executed outsides of do_write() when I enter :write into vim? As a side note, my transactional library only covers basic glibc calls, like write(), open(), rename(), remove(), etc. If vim uses some other mechanism to persist data to storage, than it's possible those calls are bypassing my library. Could someone give me a summary of how vim persists data when noswpfile is set? -- -- You received this message from the "vim_dev" maillist. Do not top-post!
