Sync crash when using with ErlyDTL Erlang


Anyone have an idea or can fix the crash problem of Sync with ErlyDTL?

Once I try to use page rendered from template by using ErlyDTL, Sync will crash and shut down the application. Here is the log below:

    application: sync

{"Kernel pid terminated",application_controller,"{application_terminated,sync,shutdown}"}

Crash dump is being written to: erl_crash.dump...done
Kernel pid terminated (application_controller) ({application_terminated,sync,shutdown})

Solution

  • I already fixed it by by changing the way to handle the DTL files in src/sync_scanner.erl and src/sync_utils.erl – Yarin Nim yesterday
