     128If a component of Sage produces a mathematical error, you should open
     129two tickets: a main ticket with all available details, and also a
     130"stopgap" ticket. This second ticket should have a patch which will be
     131merged into Sage if no one fixes the main issue; this patch should print a
     132warning when anyone uses the relevant code. To produce the warning
     133message, use code like the following::
     135    from sage.misc.stopgap import stopgap
     136    stopgap("This code contains bugs and may be mathematically unreliable.",
     137        TICKET_NUM)
     139Replace ``TICKET_NUM`` by the ticket number for the main ticket.  See
     140:trac:`12699`, for example.  On the main trac ticket, you should also
     141enter the ticket number for the stopgap ticket in the "Stopgaps"
     142field.  Stopgap tickets should be marked as blockers.
     144.. note::
     146    If mathematically valid code causes Sage to raise an error or
     147    crash, for example, there is no need for a stopgap.  Rather,
     148    stopgaps are to warn users that they may be using buggy code; if
     149    Sage crashes, this is not an issue.
