Only match credential entries with correct namespace in the Windows Credential Manager #1328
Conversation
GCM by default creates entries in the Windows Credential Manager on Windows, and prefixes the 'target name' of the entry with "git:". This 'namespace' prefix is configurable, but is not often changed in practice outside of tests. Visual Studio, when adding GitHub accounts (either natively or by the older GitHub extension for VS), it creates three credential entries: 1. GitHub for Visual Studio - https://github.com 2. git:https://github.com 3. https://github.com Entry 1 is used by VS for it's own purposes. Entry 2 is created for the benefit for GCM, so that we are 'primed'. It is unknown what entry 3 is for at this time. There is an error in our existing logic for enumerating credentials that is also matching entry 3 as well as the expected entry 2. Modify and fix the matching logic to ensure that the namespace prefix matches, rather than just stripping it and matching (even if it doesn't exist!).

In de7b93b#diff-c4c58b08f112c67b1d49742bdc348cbfc3dd410fb2e46ecfee795175d3cd5e4bL268, the modified method is marked with the comment /* for testing */, which looks a bit funny to me: is this comment obsolete? Or is this method really used only for testing?
Speaking of testing, is there a way to ensure that this does the right thing by adding a test?
The method is not used for testing, but the
Although we have tests for all sorts of matching, we never tested the matching of no-namespace credential entries.. I can add a test for |

Fixes #1325
Bug repro instructions:
At this point a window should appear asking you to select between two "Personal Access Token" accounts.
After installing the bits from this PR build (artifacts > win-x86), attempting step 4 should no longer result in a prompt to select between two "Personal Access Token" accounts.
