From c355b641769db757bc4187aa03f18510a289c86d Mon Sep 17 00:00:00 2001 From: Taylor Blau Date: Mon, 24 Jul 2023 12:39:22 -0400 Subject: [PATCH 1/5] t/lib-commit-graph.sh: allow `graph_read_expect()` in sub-directories The `graph_read_expect()` function is used to ensure that the output of the "read-graph" test helper matches certain parameters (e.g., how many commits are in the graph, which chunks were written, etc.). It expects the Git repository being tested to be at the current working directory. However, a handful of t5318 tests use different repositories stored in sub-directories. To work around this, several tests in t5318 change into the relevant repository outside of a sub-shell, altering the context for the rest of the suite. Prepare to remove these globally-scoped directory changes by teaching `graph_read_expect()` to take an optional "-C dir" to specify where the repository containing the commit-graph being tested is.

This helper takes as its second argument the location (relative to the `$TRASH_DIRECTORY`) of the Git repostiory under test. In order to run each of its commands within that repository, it first changes into that directory, without the use of a sub-shell. This pollutes future tests which expect to be run in the top-level `$TRASH_DIRECTORY` as usual. We could wrap `graph_git_behavior()` in a sub-shell, like: graph_git_behavior() { # ... ( cd "$TRASH_DIRECTORY/$DIR" && graph_git_two_modesl ) } , but since we're invoking git directly, we can pass along a "-C $DIR" when "$DIR" is non-empty. Note, however, that until the remaining callers are cleaned up to avoid changing working directories outside of a sub-shell, that we need to ensure that we are operating in the top-level $TRASH_DIRECTORY. The inner-subshell will go away in a future commit once it is no longer necessary.

Each test has mostly straightforward changes, either: - Removing the top-level `cd "$TRASH_DIRECTORY/full"`, which is unnecessary after ensuring that other tests don't change their working directory outside of a sub-shell. - Changing any Git invocations which want to be in a sub-directory by either (a) adding a "-C $DIR" argument, or (b) moving the whole test into a sub-shell. While we're here, remove any explicit "git config core.commitGraph true" invocations which were designed to enable use of the commit-graph. These are unnecessary following 31b1de6a09b (commit-graph: turn on commit-graph by default, 2019-08-13).

Now that its callers are always operating from the "$TRASH_DIRECTORY" instead of one of its sub-directories, we can drop the inner sub-shell, as it is no longer required.
