Add ./wpt run --verbose as an alias of --log-mach-level debug

[gsnedders]

It's a pain that we use something non-standard here and not that memorable.

If you don't mind, I'll take this issue.

If --verbose as an alias of --log-mach-level debug, here are my thoughts to handle the options:

• If the command line contains --verbose option only, then according to the alias rule, log_mach_level property is set to be debug.
• If the command line contains both --verbose and --log-mach-level <whatever level> options (not recommended), then I guess the attention is to set log_mach_level to be the log level value. In such case, --verbose is actually invalid and thus has no impact on the --log-mach-level option.

@gsnedders , what do you think?

[jgraham]

This won't work if implemented naively. If the logging is set to something other than mach then implying the --mach-log-level argument will just cause an error about mach logging not being enabled.

[gsnedders]

IMO, we should be trying to figure out what the current logger for stdout is (or should we go for all loggers?) and making that level debug.

[qiuzhong]

@gsnedders , do you mean --verbose should support all kinds of log formats (raw, unnitest, xunit, html, tbpl, grouped, errorsummy from the mozlog module code)? My understanding is that besides the mach format, it should also support all these formats. In other word, --verbose option should be the alias of other --log_*_level debug options automatically, not so specific.

Did I misunderstand your intention?

[qiuzhong]

@jgraham, please also make a clarification if I got you wrong.

[jgraham]

Yeah, I think you need to find a way to figure out which is going to be the stdout logger and set whatever option is required to make that verbose if it exists. This is probably better done in mozlog itself in https://searchfox.org/mozilla-central/source/testing/mozbase/mozlog/mozlog/commandline.py Note that file has an existing concept of verbose, which I think is different.
