The 'fetch follows tags by default' test sorts using 'sort -k 4', but for-each-ref output only has 3 columns. This relies on sort treating records with fewer fields as having an empty fourth field, which may produce unstable results depending on locale. Use 'sort -k 3' to match the actual number of columns in the output. Signed-off-by: Derrick Stolee <stolee@gmail.com>
Add a --must-have option to git fetch that specifies ref patterns whose tips should always be sent as "have" commits during negotiation, regardless of what the negotiation algorithm selects. Each value is either an exact ref name (e.g. refs/heads/release) or a glob pattern (e.g. refs/heads/release/*). The pattern syntax is the same as for --negotiation-tip. This is useful when certain references are important for negotiation efficiency but might be skipped by the negotiation algorithm or excluded by --negotiation-tip. Unlike --negotiation-tip which restricts the have set, --must-have is additive: the negotiation algorithm still runs and advertises its own selected commits, but the refs matching --must-have are sent unconditionally on top of those. If --negotiation-tip is used, the have set is first restricted by that option and then increased to include the tips specified by --must-have. Due to the comparision with --negotiation-tip, a previously untranslated warning around --negotiation-tip is converted into a translatable string with a swap for which option that is relevant. Getting this functionality to work requires moving these options through the transport API layer. Signed-off-by: Derrick Stolee <stolee@gmail.com>
Add a new multi-valued config option remote.<name>.mustHave that specifies ref patterns whose tips should always be sent as "have" commits during fetch negotiation with that remote. Parse the option in handle_config() following the same pattern as remote.<name>.serverOption. Store the values in a string_list on struct remote so they are available per-remote. In builtin/fetch.c, when no --must-have options are given on the command line, use the remote.<name>.mustHave config values as the default. If the user explicitly provides --must-have on the CLI, the config is not used, giving CLI precedence. Signed-off-by: Derrick Stolee <stolee@gmail.com>
When push.negotiate is enabled, send-pack spawns a 'git fetch --negotiate-only' subprocess to discover common commits. Previously this subprocess had no way to include must-have refs in the negotiation. Add a must_have field to send_pack_args, set it from the transport layer where the remote struct is available, and pass explicit --must-have arguments to the negotiation subprocess. This approach directly passes the resolved config values rather than relying on the subprocess to read remote config, which is more robust when the URL alone is used as the remote identifier.
