From e2df6c397206c3c0791fb50466789730e8a334d8 Mon Sep 17 00:00:00 2001 From: Derrick Stolee Date: Tue, 30 Mar 2021 13:10:50 +0000 Subject: test-read-cache: print cache entries with --table This table is helpful for discovering data in the index to ensure it is being written correctly, especially as we build and test the sparse-index. This table includes an output format similar to 'git ls-tree', but should not be compared to that directly. The biggest reasons are that 'git ls-tree' includes a tree entry for every subdirectory, even those that would not appear as a sparse directory in a sparse-index. Further, 'git ls-tree' does not use a trailing directory separator for its tree rows. This does not print the stat() information for the blobs. That will be added in a future change with another option. The tests that are added in the next few changes care only about the object types and IDs. However, this future need for full index information justifies the need for this test helper over extending a user-facing feature, such as 'git ls-files'. To make the option parsing slightly more robust, wrap the string comparisons in a loop adapted from test-dir-iterator.c. Care must be taken with the final check for the 'cnt' variable. We continue the expectation that the numerical value is the final argument.

Since we will no longer always expand a sparse index into a full index, add an '--expand' parameter that adds a call to ensure_full_index() so we can compare a sparse index directly against a full index, or at least what the in-memory index looks like when expanded in this way.
