#15085: :type-at/:all-types and :r don't mix -------------------------------------+------------------------------------- Reporter: dmwit | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.4.3 Component: Compiler | Version: 8.4.2 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Steps to reproduce: 1. Put `x = ()` in test.hs. 2. Start ghci. 3. Turn on collection with :set +c. 4. Load the file with :l test.hs. 5. Observe the following output from :all-types {{{ test.hs:(1,1)-(1,2): () test.hs:(1,5)-(1,7): () }}} 6. While ghci is still open, modify the file to say `x = True`. 7. In the same ghci session as before, reload with :r, or load the file again with :l test.hs, chef's choice. 8. Run :all-types again. After step 8, ghci prints the exact same thing as before, indicating that both sides of the equation have type `()`. It should instead update the source spans and types to match the file, reporting `Bool` instead of `()` and `(1,5)-(1,9)` for the second span. Manually exiting and restarting ghci appears to be the only way to freshen the collected type information. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15085 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
