From c903985bf7e772e2d08275c1a95c8a55ab011577 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Thu, 7 Nov 2024 08:57:52 +0100 Subject: credential_format(): also encode [:] An upcoming change wants to sanitize the credential password prompt where a URL is displayed that may potentially come from a `.gitmodules` file. To this end, the `credential_format()` function is employed. To sanitize the host name (and optional port) part of the URL, we need a new mode of the `strbuf_add_percentencode()` function because the current mode is both too strict and too lenient: too strict because it encodes `:`, `[` and `]` (which should be left unencoded in `:` and in IPv6 addresses), and too lenient because it does not encode invalid host name characters `/`, `_` and `~`. So let's introduce and use a new mode specifically to encode the host name and optional port part of a URI, leaving alpha-numerical characters, periods, colons and brackets alone and encoding all others. This only leads to a change of behavior for URLs that contain invalid host names.
