Subject: Re: [PATCH v2] completion: reduce overhead of clearing cached --options
Date: Mon, 7 May 2018 11:05:41 -0400 [thread overview]
Message-ID: <21289682-5B46-4131-B7D7-57CE9F391B9D@1eanda.com> (raw)
In-Reply-To: <xmqqh8o9l7n4.fsf@gitster-ct.c.googlers.com>
I haven't seen any discussion about this recently. What are the chances of getting it merged? I'd like to see this included in 2.18.
>> To get the names of all '$__git_builtin_*' variables caching --options
>> of builtin commands in order to unset them, 8b0eaa41f2 (completion:
>> clear cached --options when sourcing the completion script,
>> 2018-03-22) runs a 'set |sed s///' pipeline. This works both in Bash
>> and in ZSH, but has a higher than necessary overhead with the extra
>> processes.
>>
>> In Bash we can do better: run the 'compgen -v __gitcomp_builtin_'
>> builtin command, which lists the same variables, but without a
>> pipeline and 'sed' it can do so with lower overhead.
>> ZSH will still continue to run that pipeline.
>>
>> This change also happens to work around an issue in the default Bash
>> ...
>> Updated the commit message to explicitly mention that ZSH is
>> unaffected. The patch is the same.

> Thanks.
