Subject: Fix: lttng: add-context: silence coverity warning
X-Git-Url: http://git.lttng.org/?a=commitdiff_plain;h=261e7f1360fffe91b0b690c8a0715f4f6d2c4a7e;hp=261e7f1360fffe91b0b690c8a0715f4f6d2c4a7e;p=lttng-tools.git

Fix: lttng: add-context: silence coverity warning

Coverity reports that:
  1464653 Uninitialized scalar field
  The field will contain an arbitrary value left over from earlier
  computations.

  In ctx_opts::​ctx_opts(): A scalar field is not initialized by the
  constructor.

   uninit_member: Non-static class member hide_help is not initialized
   in this constructor nor in any functions that it calls.

In our case it doesn't matter since a nullptr symbol indicates the end
the ctx_opts array. An "unknown" value is added to the context array
and used to initialize the end-of-list item to an invalid value.

Calling the ctx_opts(const char *symbol_, context_type ctx_type_, bool
hide_help_ = false) constructor causes `hide_help` to be initialized.
