Moving files across phyiscal devices fails #117

Open salbeira opened 5 months ago

salbeira commented 5 months ago

Haskell uses renameFile to move files from the "new" /tmp/ directory to the decker directory after operations such as decker crunch.

renameFile is allowed - and does - fail if it is done across "physical devices" (but needs to document this fact ... but I wonder where ...).

This completely fails in the case where your /tmp/ is in a tmpfs.

I believe I encountered a similar issue quite a while back and was able to resolve it by first doing a COPY from the temporary directory to the target and then removing the tmp file. Assinine, but works across phyiscal devices in haskell.

@monofon can you look into it?

@salbeira @monofon This issue also effects the ability to generate any extern input, such as graphviz plots or tex stuff. :(
