Refactored createGroupChannel in server/channels/app/channel.go
to use SaveMultipleMembers for saving channel members, replacing the previous loop of individual SaveMember calls.

The Problem
The previous implementation of
createGroupChannel
iterated through the list of users and called SaveMember for each one. This resulted in N+1 database queries (where N is the number of users in the group), which is inefficient and can lead to performance issues as the group size increases.

The Solution
I replaced the loop with a single call to SaveMultipleMembers, which allows inserting all channel members in a single database operation (or fewer operations depending on the store implementation). This significantly reduces the database overhead.

Contribution License Agreement

This Contribution License Agreement (“Agreement”) is agreed to by the party signing below (“You”),
and conveys certain license rights to Microsoft Corporation and its affiliates (“Microsoft”) for Your

    approved by the Open Source Initiative (www.opensource.org).
    “Submit” is the act of uploading, submitting, transmitting, or distributing code or other content to any
    Project, including but not limited to communication on electronic mailing lists, source code control
    systems, and issue tracking systems that are managed by, or on behalf of, the Project for the purpose of
    discussing and improving that Project, but excluding communication that is conspicuously marked or
    otherwise designated in writing by You as “Not a Submission.”
    “Submission” means the Code and any other copyrightable material Submitted by You, including any
    associated comments and documentation.
  2. Your Submission. You must agree to the terms of this Agreement before making a Submission to any
    Project. This Agreement covers any and all Submissions that You, now or in the future (except as
    described in Section 4 below), Submit to any Project.
  3. Originality of Work. You represent that each of Your Submissions is entirely Your original work.
    Should You wish to Submit materials that are not Your original work, You may Submit them separately
    to the Project if You (a) retain all copyright and license information that was in the materials as You
    received them, (b) in the description accompanying Your Submission, include the phrase “Submission
    containing materials of a third party:” followed by the names of the third party and any licenses or other

    guidelines concerning Submissions.
  4. Your Employer. References to “employer” in this Agreement include Your employer or anyone else

    Submission is made in the course of Your work for an employer or Your employer has intellectual
    property rights in Your Submission by contract or applicable law, You must secure permission from Your
    employer to make the Submission before signing this Agreement. In that case, the term “You” in this
    Agreement will refer to You and the employer collectively. If You change employers in the future and
    desire to Submit additional Submissions for the new employer, then You agree to sign a new Agreement
    and secure permission from the new employer before Submitting those Submissions.
  5. Licenses.
  • Copyright License. You grant Microsoft, and those who receive the Submission directly or
    indirectly from Microsoft, a perpetual, worldwide, non-exclusive, royalty-free, irrevocable license in the
    Submission to reproduce, prepare derivative works of, publicly display, publicly perform, and distribute

  • Patent License. You grant Microsoft, and those who receive the Submission directly or
    indirectly from Microsoft, a perpetual, worldwide, non-exclusive, royalty-free, irrevocable license under
    Your patent claims that are necessarily infringed by the Submission or the combination of the
    Submission with the Project to which it was Submitted to make, have made, use, offer to sell, sell and
    import or otherwise dispose of the Submission alone or with the Project.
  • Other Rights Reserved. Each party reserves all rights not expressly granted in this Agreement.
    No additional licenses or rights whatsoever (including, without limitation, any implied licenses) are

    employer or Your employer has intellectual property rights in Your Submission by contract or applicable
    law. If You are signing this Agreement on behalf of Your employer, You represent and warrant that You
    have the necessary authority to bind the listed employer to the obligations contained in this Agreement.
    You are not expected to provide support for Your Submission, unless You choose to do so. UNLESS

Pull request overview

This PR fixes a parser bug where triple-slash reference directives required attributes to be in a specific order. The title accurately describes the change ("Fix: Allow arbitrary attribute order in triple-slash directives"), but the description is completely incorrect and appears to be from a different pull request about Go/Mattermost database optimization.

Key Changes

  • Updated regex patterns for fullTripleSlashReferencePathRegEx and fullTripleSlashReferenceTypeReferenceDirectiveRegEx to allow optional attributes before the main path or types attribute
  • Added a test case demonstrating that <reference resolution-mode="import" path="./foo.d.ts" /> now works correctly
  • Applied consistent formatting/indentation improvements throughout src/compiler/utilities.ts for better code readability

PR Metadata Issue: The PR title mentions "Fix: Allow arbitrary attribute order in triple-slash directives" but the description talks about "createGroupChannel in server/channels/app/channel.go". This description appears to be from a completely different pull request (likely a Go/Mattermost server PR about database optimization). The PR description should be updated to match the actual changes being made to TypeScript's triple-slash directive parsing.

The test only covers the case where resolution-mode appears before path. Consider adding a test case for the traditional order (path before resolution-mode) to ensure backward compatibility and that both orderings work correctly. For example:

/// <reference path="./foo.d.ts" resolution-mode="import" />
