Concurrency issue when generating identical graphs about pandoc-plot HOT 4 CLOSED

Version 1.5.5 has just been released. It should fix your issue. Please give it a try and let me know how it goes.

Hi Ben,

Thank you for your bug report.

This is because the content of each script is hashed, and the hash determines the filename. This means that two scripts with the same content will be exported to the same file, as you pointed out.

The reason for this was to prevent pandoc-plot from re-generating plots on large documents. So if I change a single plot script in a 500 pages book, only 1 plot will be re-generated. If pandoc-plot added a randomly-generated string to every plot, then I would lose the 'caching' feature.

If you have N identical plot scripts (all with an identical hash value), then pandoc-plot could generate only 1 figure. Then, in the final document, you would have N links to the same file. Would that solution work for you?

I've opted for the crude fix for now: add a lock to file writing operations. Most of the time is spent rendering figures anyways, so this lock won't have much effect on performance.

Once the tests pass, including a new one replicating the issue you reported, I'll make a new release.

I'll close this for now, as version 1.5.5 should fix this issue. If not, please don't hesitate to re-open the issue.
