  • Review implementation for correctness
  • Fix bug in azd.ts: getAzureDevOpsHostname() was returning regex-escaped hostname, causing SSH hostname comparison azDevOpsHostname === "dev.azure.com" to always fail (escaped value is "dev\.azure\.com")
  • Fix bug in azd.ts: SSH hostname was being double-escaped (already-escaped value passed to escapeStringRegexp again)
  • Fix gitHub.ts: Replace manual regex escaping (.replace(/[\\.]/g, '\\$&')) with proper escapeStringRegexp from library for consistent, complete escaping
  • Validate esbuild succeeds (TS1479 for escape-string-regexp is a pre-existing issue, handled by esbuild's ESM interop)

To address the issue, we need to ensure that the literal dot (.) in ssh.dev.azure.com is properly escaped when constructing the regex. This can be achieved by applying the same escaping logic as done for azDevOpsHostname earlier in the code. Specifically, the replace(/\./g, '\\.') method should be applied to sshHostname before it is used as part of a regex.

Changes will be made to the line constructing escapedSshHostname on line 42 to ensure the dot is escaped. This ensures the regex matches the exact hostname without allowing unintended matches.

Incomplete string escaping or encoding High documentation

This does not escape backslash characters in the input.

Copilot Autofix

AI 8 months ago

To fix the issue, we need to ensure that backslashes in the customHostname (or the default value "dev.azure.com") are escaped before constructing the regular expression. This can be achieved by chaining a .replace(/\\/g, '\\\\') call before escaping dots. This approach is consistent with the escaping logic used elsewhere in the file (e.g., line 13).

The updated code will:

  1. Escape backslashes first using .replace(/\\/g, '\\\\').
  2. Escape dots using .replace(/\./g, '\\.').

The fix will be applied to line 33 where azDevOpsHostname is defined.

Copilot Autofix

AI 8 months ago

To fix the issue, we need to ensure that the escaping is performed correctly and consistently. Specifically:

  1. The backslash (\) should be escaped only once, and this escaping should occur after all other characters (like .) have been escaped.
  2. The order of escaping operations should be adjusted to avoid double-escaping. For example, the . character should be escaped first, followed by the \ character.

The fix involves reordering the escaping operations and ensuring that backslashes are escaped only once, after all other characters have been processed.

Fix hostname escaping bugs in azd.ts and gitHub.ts regex patterns

@copilot verify the implementation again with a newer and better modal

Re-verified the implementation and found two bugs that have been fixed in commit 183694c:

  1. Double-escaping / wrong comparison in azd.ts: getAzureDevOpsHostname() was returning the regex-escaped hostname (e.g. "dev\.azure\.com"), but the SSH pattern fallback compared it against the plain string "dev.azure.com" — always false. The escaped value was also passed to escapeStringRegexp() again, causing double-escaping. Fixed by returning the raw hostname from getAzureDevOpsHostname() and escaping only at the regex construction sites.

  2. Incomplete regex escaping in gitHub.ts: Was using a manual .replace(/[\\.]/g, '\\$&') which only escapes dots and backslashes. Replaced with escapeStringRegexp (already used in azd.ts) for complete and correct escaping of all regex special characters in hostnames.
