perf(bash-v2): standard completion optimizations #1683

scop · 2022-04-28T20:48:27Z

Refactor to remove two loops over the entire list of candidates.

Format descriptions only for completions that are actually going to be displayed, instead of for all candidates.

Format descriptions inline in completions array, removing need for a command substitution/subshell and a printf escape per displayed completion.

These changes shave off a second or so from my case at hand in #1680, it was roughly ~1.7s before, is now ~0.7s after.
The diff is largish, but the bulk of it is in __%[1]s_format_comp_descriptions due to indentation changes, there aren't that many lines actually changed in it either. git show -w helps with the review.

Caveat: I have not actually tested generating completions with this code. I worked on the improvements by tweaking an existing emitted completion shell file, then manually ported the changes to the template in Go code here. Hopefully I didn't introduce bugs while doing that. (The code compiles, and test suite fails just like it did before this change, no regressions noticed.)

(Test suite fix is #1684.)

(Force-pushed just to generalize the commit message some.)

marckhouzam · 2022-04-29T12:53:03Z

Thanks @scop ! I will have a look over the weekend.

bash_completionsV2.go

        # Strip any description before checking the length
-        comp=${comp%%%%$tab*}
+        comp=${compline%%$tab*}
        # Only consider the completions that match
        comp=$(compgen -W "$comp" -- "$cur")


Doing this for every candidate separately would be something to look into getting rid of next, but I suggest we postpone looking into it as far as this PR is concerned and not get delayed because of it here.

Things are getting faster 🎉

I didn't finish the review yet but the following changes are necessary no matter what, so I'm posting them now.

Thanks! Addressed. Quite a bit more care would have been required for the method I used to do make the submitted change. Will have a look at the other open PR if it had similar issues.

bash_completionsV2.go

marckhouzam

This is great!

The https://github.com/marckhouzam/cobra-completion-testing tests pass and we can see a nice improvement in speed using marckhouzam/cobra-completion-testing#15. On my machine I see :

1000 completions without descriptions 2.688s sec on master -> 1.073 sec with the PR
1000 completions with descriptions 2.965s sec on master -> 1.245 sec with the PR

The helm completion tests also pass and I did some manual testing too.

Excellent work @scop, thank you!

I will go ahead and merge to continue working on the other speed improvements.

style(bash-v2): out is not an array variable, do not refer to it as such Even though this to my surprise works, it doesn't accomplish anything but some confusion. Remove it. Merge spf13/cobra#1681 --- perf(bash-v2): use backslash escape string expansion for tab Using a command substitution, i.e. a subshell, with `printf` is expensive for this purpose. For example `__*_format_comp_descriptions` is run once for each completion candidate; the expense adds up and shows when there are a lot of them. This shaves off roughly 25% of the times I receive for my test case in #1680 (~2 seconds before, ~1.5 after). Merge spf13/cobra#1682 --- perf(bash-v2): standard completion optimizations Refactor to remove two loops over the entire list of candidates. Format descriptions only for completions that are actually going to be displayed, instead of for all candidates. Format descriptions inline in completions array, removing need for a command substitution/subshell and a printf escape per displayed completion. These changes shave off a second or so from my case at hand in #1680, it was roughly ~1.7s before, is now ~0.7s after. The diff is largish, but the bulk of it is in `__%[1]s_format_comp_descriptions` due to indentation changes, there aren't that many lines actually changed in it either. `git show -w` helps with the review. Caveat: I have not actually tested generating completions with this code. I worked on the improvements by tweaking an existing emitted completion shell file, then manually ported the changes to the template in Go code here. Hopefully I didn't introduce bugs while doing that. (The code compiles, and test suite fails just like it did before this change, no regressions noticed.) Merge spf13/cobra#1683 --- perf(bash-v2): short-circuit descriptionless candidate lists If the list of candidates has no descriptions, short circuit all the description processing logic, basically just do a `compgen -W` for the whole list and be done with it. We could conceivably do some optimizations like this and more when generating the completions with `--no-descriptions` in Go code, by omitting some parts we know won't be needed, or doing some things differently. But doing it this way in bash, the improvements are available also to completions generated with descriptions enabled when they are invoked for completion cases that produce no descriptions. The result after this for descriptionless entries seems fast enough so it seems there's no immediate need to look into doing that. This alone pretty much eliminates all the slowness related to my specific use case in #1680, bringing it down to ~0.07s (yes, there _is_ a zero on the right of the period), so for the time being I'm not inclined to look into further optimizations at least for the code path where there are no descriptions. Related to #1683, but I suggest merging both as they affect different scenarios. Same caveat as in #1683 about testing and the way the change was made applies here. Merge spf13/cobra#1686 --- perf(bash-v2): speed up filtering entries with descriptions Use simple prefix match instead of single word `compgen -W` command substitution for each candidate match. It's a bit late, but I can't think of a case where this replacement wouldn't be ok this late at night. Performancewise this improves the cases with descriptions quite a bit, with current marckhouzam/cobra-completion-testing#15 on my box, the v2 numbers look like the following (I've stripped the v1 numbers from each list below). Before (current master, #1686 not merged yet): ``` Processing 1000 completions took 0.492 seconds which is less than the 1.0 seconds limit Processing 1000 completions took 0.600 seconds which is less than the 2.0 seconds limit Processing 1000 completions took 0.455 seconds which is less than the 1.0 seconds limit Processing 1000 completions took 0.578 seconds which is less than the 2.0 seconds limit Processing 1000 completions took 0.424 seconds which is less than the 1.0 seconds limit Processing 1000 completions took 0.570 seconds which is less than the 2.0 seconds limit Processing 1000 completions took 0.502 seconds which is less than the 1.0 seconds limit Processing 1000 completions took 0.585 seconds which is less than the 2.0 seconds limit ``` After (also without #1686): ``` Processing 1000 completions took 0.070 seconds which is less than the 1.0 seconds limit Processing 1000 completions took 0.165 seconds which is less than the 2.0 seconds limit Processing 1000 completions took 0.072 seconds which is less than the 1.0 seconds limit Processing 1000 completions took 0.181 seconds which is less than the 2.0 seconds limit Processing 1000 completions took 0.089 seconds which is less than the 1.0 seconds limit Processing 1000 completions took 0.254 seconds which is less than the 2.0 seconds limit Processing 1000 completions took 0.058 seconds which is less than the 1.0 seconds limit Processing 1000 completions took 0.122 seconds which is less than the 2.0 seconds limit ``` For curiosity, even though this improves the descriptionless case quite a bit too, #1686 is still relevant, with it applied on top of this one: ``` Processing 1000 completions took 0.036 seconds which is less than the 1.0 seconds limit Processing 1000 completions took 0.165 seconds which is less than the 2.0 seconds limit Processing 1000 completions took 0.047 seconds which is less than the 1.0 seconds limit Processing 1000 completions took 0.183 seconds which is less than the 2.0 seconds limit Processing 1000 completions took 0.051 seconds which is less than the 1.0 seconds limit Processing 1000 completions took 0.264 seconds which is less than the 2.0 seconds limit Processing 1000 completions took 0.036 seconds which is less than the 1.0 seconds limit Processing 1000 completions took 0.122 seconds which is less than the 2.0 seconds limit ``` Merge spf13/cobra#1689 --- fix(bash-v2): skip empty completions when filtering descriptions `read` gives a last null value following a trailing newline. Regression from fb8031162c2ffab270774f13c6904bb04cbba5a7. We could drop the `\n` from the feeding `printf` to accomplish the same end result, but I'm planning to submit some related cleanups a bit later that wouldn't play well with that approach, so I went with explicit filtering here. Merge spf13/cobra#1691 --- perf(bash-v2): speed up filtering menu-complete descriptions Similarly as fb8031162c2ffab270774f13c6904bb04cbba5a7 (+ the empty entry fix in spf13/cobra#1691) did for the "regular", non-menu completion cases. I have no numbers on this, but I'm assuming the speedups seen elsewhere are here too, and didn't notice anything breaking in casual manual tests. Could be useful to add some perf numbers for the menu-complete code path too to [marckhouzam/cobra-completion-testing](https://github.com/marckhouzam/cobra-completion-testing/) (maybe as well as other tests, haven't checked if there are any). Merge spf13/cobra#1692 --- perf(bash-v2): read directly to COMPREPLY on descriptionless short circuit Not that it'd really matter that much performancewise given the level we are at for this case, but this change makes the short circuit roughly twice as fast on my box as it was for the 1000 rounds done in marckhouzam/cobra-completion-testing. Perhaps more importantly, this makes the code arguably slightly cleaner. Before: ``` ... <= TIMING => no descriptions: 1000 completions took 0.039 seconds < 0.2 seconds limit ... <= TIMING => no descriptions: 1000 completions took 0.046 seconds < 0.2 seconds limit ... ``` After: ``` ... <= TIMING => no descriptions: 1000 completions took 0.022 seconds < 0.2 seconds limit ... <= TIMING => no descriptions: 1000 completions took 0.024 seconds < 0.2 seconds limit ... ``` Merge spf13/cobra#1700

Cobra would never be possible without your contributions! 🐍 **Full Changelog**: spf13/cobra@v1.5.0...v1.6.0 ### [`v1.5.0`](https://togithub.com/spf13/cobra/releases/tag/v1.5.0) [Compare Source](https://togithub.com/spf13/cobra/compare/v1.4.0...v1.5.0) #### Spring 2022 Release 🌥️ Hello everyone! Welcome to another release of cobra. Completions continue to get better and better. This release adds a few really cool new features. We also continue to patch versions of our dependencies as they become available via dependabot. Happy coding! #### Active help 👐🏼 Shout out to [@marckhouzam](https://togithub.com/marckhouzam) for a big value add: Active Help [https://github.com/spf13/cobra/pull/1482](https://togithub.com/spf13/cobra/pull/1482). With active help, a program can provide some inline warnings or hints for users as they hit tab. Now, your CLIs can be even more intuitive to use! Currently active help is only supported for bash V2 and zsh. Marc wrote a whole guide on how to do this, so make sure to give it a good read to learn how you can add this to your cobra code! https://github.com/spf13/cobra/blob/master/active_help.md #### Group flags 🧑🏼‍🤝‍🧑🏼 Cobra now has the ability to mark flags as required or exclusive as a ***group***. Shout out to our newest maintainer [@johnSchnake](https://togithub.com/johnSchnake) for this! [https://github.com/spf13/cobra/pull/1654](https://togithub.com/spf13/cobra/pull/1654) Let's say you have a `username` flag that ***MUST*** be partnered with a `password` flag. Well, now, you can enforce those as being required together: ```go rootCmd.Flags().StringVarP(&u, "username", "u", "", "Username (required if password is set)") rootCmd.Flags().StringVarP(&pw, "password", "p", "", "Password (required if username is set)") rootCmd.MarkFlagsRequiredTogether("username", "password") ``` Flags may also be marked as "mutally exclusive" with the `MarkFlagsMutuallyExclusive(string, string ... )` command API.

great work everyone!! Cobra and it's huge impact wouldn't be possible without you 👏🏼 🚀 🐍 **Full Changelog**: spf13/cobra@v1.4.0...v1.5.0 ### [`v1.4.0`](https://togithub.com/spf13/cobra/releases/tag/v1.4.0) [Compare Source](https://togithub.com/spf13/cobra/compare/v1.3.0...v1.4.0) ### Winter 2022 Release ❄️ Another season, another release! #### Goodbye viper! 🐍 🚀 The core Cobra library no longer requires Viper and all of its indirect dependencies. This means that Cobra's dependency tree has been drastically thinned! The Viper dependency was included because of the `cobra` CLI generation tool. [This tool has migrated to `spf13/cobra-cli`](https://togithub.com/spf13/cobra-cli/releases/tag/v1.3.0). It's *pretty unlikely* you were importing and using **the bootstrapping CLI tool** as part of your application (after all, it's just a tool to get going with core `cobra`). But if you were, replace occurrences of "github.com/spf13/cobra/cobra" with "github.com/spf13/cobra-cli" And in your `go.mod`, you'll want to also include this dependency: github.com/spf13/cobra-cli v1.3.0 Again, the maintainers *do not anticipate* this being a breaking change to users of the core `cobra` library, so minimal work should be required for users to integrate with this new release. Moreover, this means the dependency tree for your application using Cobra should no longer require dependencies that were inherited from Viper.

This release focuses on code completions, several critical bug fixes, some documentation updates, and security bumps. Upgrading should be simple but please take note of the introduction of bash completions V2 and their default use. The v1 completions library is still available, but will be *deprecated* in the future. Please open an issue with any problems! *** #### New Features - Automatically adds a `completion` command for shell completions. If a `completion` command is already provided, uses that instead. This will *automatically* provide shell completions for bash, zsh, fish, and PowerShell [https://github.com/spf13/cobra/pull/1192](https://togithub.com/spf13/cobra/pull/1192) - Users can configure the command auto creation: - disable the creation of the completion command - disable completion descriptions - disable the `--no-descriptions` flag for "always on" completion descriptions - Introduction of bash completions V2, a uniform completion approach which include completion descriptions. The V1 bash completions are still available *but will be deprecated* in a later release - [https://github.com/spf13/cobra/pull/1146](https://togithub.com/spf13/cobra/pull/1146) - Note that projects providing completion through a different command name (say a command named "complete") will continue to use v1 for their own command but will also provide cobra's implicit "completion" command which will use v2, unless of course, these projects take the time to disable the default "completion" command as noted above. - Commands now support context being passed to completions - [https://github.com/spf13/cobra/pull/1265](https://togithub.com/spf13/cobra/pull/1265) - An example can be found here: [https://github.com/spf13/cobra/pull/1265#issuecomment-734551031](https://togithub.com/spf13/cobra/pull/1265#issuecomment-734551031) - Removed dependency on`mitchellh/go-homedir` in favor of core Go `os.UserHomeDir()` - spf13/cobra@8eaca5f #### Bug Fixes - Fix trailing whitespace not being handled in powershell completion scripts [https://github.com/spf13/cobra/pull/1342](https://togithub.com/spf13/cobra/pull/1342) - Bash completion variable leak fix [https://github.com/spf13/cobra/pull/1352](https://togithub.com/spf13/cobra/pull/1352) - Fish shell completions correctly ignore trailing empty lines [https://github.com/spf13/cobra/pull/1284](https://togithub.com/spf13/cobra/pull/1284) - PowerShell completions fix for "no file comp directive" - [https://github.com/spf13/cobra/pull/1363](https://togithub.com/spf13/cobra/pull/1363) - Custom completions now correctly handle multiple shorthand flags together - [https://github.com/spf13/cobra/pull/1258](https://togithub.com/spf13/cobra/pull/1258) - zsh completions now correctly handle `ShellDirectiveCompletionNoSpace` and file completion all the time - [https://github.com/spf13/cobra/pull/1213](https://togithub.com/spf13/cobra/pull/1213) - Multiple fixes / improvements to the fish shell support - [https://github.com/spf13/cobra/pull/1249](https://togithub.com/spf13/cobra/pull/1249) - Fix home directory config not loading correctly - [https://github.com/spf13/cobra/pull/1282](https://togithub.com/spf13/cobra/pull/1282) - Fix for `RegisterFlagCompletionFunc` as a global var not working in multi-threaded programs: [https://github.com/spf13/cobra/pull/1423](https://togithub.com/spf13/cobra/pull/1423) - Custom completions correctly do not complete flags after args when interspersed is false [#1308](https://togithub.com/spf13/cobra/issues/1308) #### Testing - Deprecated Travis CI. Now fully using Github Actions - spf13/cobra@d0f318d - Added test cases and enhancements (thank you to everyone for taking the time to add tests to your PRs!) - Shoutout to [@marckhouzam](https://togithub.com/marckhouzam) and [@Luap99](https://togithub.com/Luap99) for their hard work on a cobra command completions testing library. [Check out the repo here!](https://togithub.com/marckhouzam/cobra-completion-testing) #### Security - Bump viper to 1.8.1. This corrects several issues with vulnerabilities existing in the dependency tree - [https://github.com/spf13/cobra/pull/1433](https://togithub.com/spf13/cobra/pull/1433) #### Other - Add PR labeler with pull_request_target to enable tests to run from forks - [https://github.com/spf13/cobra/pull/1338](https://togithub.com/spf13/cobra/pull/1338) - CI using MSYS2 windows machines pull latest - [https://github.com/spf13/cobra/pull/1366](https://togithub.com/spf13/cobra/pull/1366) - Multiple small fixes to spelling / documentation - [https://github.com/spf13/cobra/pull/1349](https://togithub.com/spf13/cobra/pull/1349) [https://github.com/spf13/cobra/pull/1417](https://togithub.com/spf13/cobra/pull/1417) [https://github.com/spf13/cobra/pull/1434](https://togithub.com/spf13/cobra/pull/1434) **Thank you to *all* our amazing contributors 🐍🚀** </details> --- ### Configuration 📅 **Schedule**: Branch creation - At any time (no schedule defined), Automerge - At any time (no schedule defined). 🚦 **Automerge**: Disabled by config.
