1131 | * We have a chicken-and-egg situation between initializing the refdb | |
1132 | * and spawning transport helpers: | |
1133 | * | |
1134 | * - Initializing the refdb requires us to know about the object | |
1135 | * format. We thus have to spawn the transport helper to learn | |
1136 | * about it. | |
1137 | * | |
1138 | * - The transport helper may want to access the Git repository. But | |
1139 | * because the refdb has not been initialized, we don't have "HEAD" | |
1140 | * or "refs/". Thus, the helper cannot find the Git repository. | |
1141 | * | |
1142 | * Ideally, we would have structured the helper protocol such that it's | |
1143 | * mandatory for the helper to first announce its capabilities without | |
1144 | * yet assuming a fully initialized repository. Like that, we could | |
1145 | * have added a "lazy-refdb-init" capability that announces whether the | |
1146 | * helper is ready to handle not-yet-initialized refdbs. If any helper | |
1147 | * didn't support them, we would have fully initialized the refdb with | |
1148 | * the SHA1 object format, but later on bailed out if we found out that | |
1149 | * the remote repository used a different object format. | |
1150 | * | |
1151 | * But we didn't, and thus we use the following workaround to partially | |
1152 | * initialize the repository's refdb such that it can be discovered by | |
1153 | * Git commands. To do so, we: | |
1154 | * | |
1155 | * - Create an invalid HEAD ref pointing at "refs/heads/.invalid". | |
1156 | * | |
1157 | * - Create the "refs/" directory. | |
1158 | * | |
1159 | * - Set up the ref storage format and repository version as | |
1160 | * required. | |
1161 | * | |
1162 | * This is sufficient for Git commands to discover the Git directory. | |
