sqlite3_trace() sometimes does not invoke its callback
User & Date: drh 2014-08-19 19:57:38

  1. Change foundin to "3.8.6"
  2. Change icomment to:

    The callback to sqlite3_trace() is suppose to be invoked for every SQL statement that is run by the VDBE. But sometimes the callback will be suppressed. If the prepared statement is marked as expired (which can happen, for example, if the RHS of an expression like "x GLOB ?1" is rebound and X is an indexed text column) then the callback is not invoked. This can be seen in the shell by running:

    .trace stderr

    The SELECT statement that implements the ".tables" command is not traced.

    This problem appears to have existed since 2012-10-03, version 3.7.15 and check-in [39f763bfc04174ee0fe2cdf6a92]. The problem was discovered during internal testing and has not been observed in the wild.

  3. Change login to "drh"
  4. Change mimetype to "text/x-fossil-wiki"
  5. Change severity to "Minor"
  6. Change status to "Open"
  7. Change title to:

    sqlite3_trace() sometimes does not invoke its callback

  8. Change type to "Code_Defect"
