6 | * This header centralizes the declaration of our libcurl dependencies | |
7 | * to make it easy to discover the oldest versions we support, and to | |
8 | * inform decisions about removing support for older libcurl in the | |
9 | * future. | |
10 | * | |
11 | * The oldest supported version of curl is documented in the "INSTALL" | |
12 | * document. | |
13 | * | |
14 | * The source of truth for what versions have which symbols is | |
15 | * https://github.com/curl/curl/blob/master/docs/libcurl/symbols-in-versions; | |
16 | * the release dates are taken from curl.git (at | |
17 | * https://github.com/curl/curl/). | |
18 | * | |
19 | * For each X symbol we need from curl we define our own | |
20 | * GIT_CURL_HAVE_X. If multiple similar symbols with the same prefix | |
21 | * were defined in the same version we pick one and check for that name. | |
22 | * | |

23 | * We may also define a missing CURL_* symbol to its known value, if |
24 | * doing so is sufficient to add support for it to older versions that | |
25 | * don't have it. | |
26 | * | |
e4ff3b67 ÆAB |
27 | * Keep any symbols in date order of when their support was |
28 | * introduced, oldest first, in the official version of cURL library. | |
