[3.3.0, MacOS X] Temporary files and read-only directories

[Mike Smith]

[obligatory thanks for a very useful application]

One common phase of my workflow is to audit source changes between built versions of a product. The sources for each build are archived in read-only folders on a network share.

When comparing two files in this situation, DiffMerge presents a dialog complaining that it "Failed to create a temporary file name (error 13: Permission denied)".

From a user's perspective, it would make sense for the compare to open in a read-only fashion (i.e. automatically applying the --ro2 option). The dialog is perhaps more intrusive and annoying than necessary to communicate that changes can't be made in the new window.

Good point. It should either sense that everything is read-only and force the --ro2 or
it should create the temp file in the platform-equivalent of /tmp or maybe both. But
if everything is read-only, it doesn't really need the temp file (it's only used for auto-save).

I've logged this.

Thanks for the report,
jeff
