Subject: Fix: lttng: incorrect domain list printed when no domain is provided
X-Git-Tag: v2.11.3~5
X-Git-Url: https://git.lttng.org/?a=commitdiff_plain;h=bf19009767db1b69e7c9badfab564aa30ea28ad6;hp=bf19009767db1b69e7c9badfab564aa30ea28ad6;p=lttng-tools.git

Fix: lttng: incorrect domain list printed when no domain is provided

The following commands make use of a common utility function to
validate the count of domains specified and print an error when it
is invalid:
  - lttng-enable-event,
  - lttng-disable-event,
  - lttng-track,
  - lttng-untrack,
  - lttng-add-context,
  - lttng-enable-channel,
  - lttng-disable-channel.

Those commands do not allow the same domains to be used. In fact, they
all expect --kernel or --userspace only, except for the
lttng-enable-event, lttng-disable-event, and lttng-add-context
commands which allow the --log4j, --jul, and --python domain options
to be used.

Currently, the error message when no domain is specified is incorrect
for all of those commands. The error reads as follows:

`Error: Please specify a domain (-k/-u/-j).`

For most commands, the -j option cannot be used. For those that allow
agent domains, the message is missing the -l and -p domains.

This ensures that the expected domains are printed for each of those
commands.

Moreover, the message is clarified by using the long form option
names.
