Description

If I run:
cl-update --help

it runs:
/usr/bin/git --git-dir /usr/portage/.git --work-tree /usr/portage status -b --porcelain

before it gets around to printing the help.

Does this make sense?

It seems that this behavior would have to affect any other code that uses main in cl_server - not that it will run git, but that it will do something other than just printing the help for the command. For example, when I try "cl-core-request-show --help" it takes several seconds before I get the command help.

History

Updated by Scott Bertilson over 4 years ago

I see that the git request is also done for cl-core-variables-show. I can tell that it is cached, but the interval seems fairly short - less than an hour.

Actually, it doesn't seem consistently cached because I ran the command several times within about 20 seconds and the first 2 times it ran git, but then it didn't any more.

Actually, I'm now thinking that the succeeding git runs must have been so fast that I didn't see them because I'm watching with top and have noticed that they go by very fast if the update interval is timed right.

Planted a wrapper script in place of git so I could log the invocations.

The following is what I see for cl-update --help
/usr/bin/git --git-dir /usr/portage/.git --work-tree /usr/portage status -b --porcelain

As a result, it takes over 2.5 minutes before the help output is displayed.

The problem will be resolved in calculate-utils-3.4.
