| Developer Notes | ||
| =============== | ||
|
|
||
| * The distributed `ares_build.h` in the official release tarballs is only | ||
| intended to be used on systems which can also not run the also distributed | ||
| `configure` or `CMake` scripts. It is generated as a copy of | ||
| `ares_build.h.dist` as can be seen in the code repository. | ||
|
|
||
| * If you check out from git on a non-`configure` or `CMake` platform, you must run | ||
| the appropriate `buildconf*` script to set up `ares_build.h` and other local | ||
| files before being able to compile the library. There are pre-made makefiles | ||
| for a subset of such systems such as Watcom, NMake, and MinGW Makefiles. | ||
|
|
||
| * On systems capable of running the `configure` or `CMake` scripts, the process | ||
| will overwrite the distributed `ares_build.h` file with one that is suitable | ||
| and specific to the library being configured and built, this new file is | ||
| generated from the `ares_build.h.in` and `ares_build.h.cmake` template files. | ||
|
|
||
| * If you intend to distribute an already compiled c-ares library you **MUST** | ||
| also distribute along with it the generated `ares_build.h` which has been | ||
| used to compile it. Otherwise, the library will be of no use for the users of | ||
| the library that you have built. It is **your** responsibility to provide this | ||
| file. No one at the c-ares project can know how you have built the library. | ||
| The generated file includes platform and configuration dependent info, | ||
| and must not be modified by anyone. | ||
|
|
||
| * We support both the AutoTools `configure` based build system as well as the | ||
| `CMake` build system. Any new code changes must work with both. | ||
|
|
||
| * The files that get compiled and are present in the distribution are referenced | ||
| in the `Makefile.inc` in the current directory. This file gets included in | ||
| every build system supported by c-ares so that the list of files doesn't need | ||
| to be maintained per build system. Don't forget to reference new header files | ||
| otherwise they won't be included in the official release tarballs. | ||
|
|
||
| * We cannot assume anything else but very basic C89 compiler features being | ||
| present. The lone exception is the requirement for 64bit integers which is | ||
| not a requirement for C89 compilers to support. Please do not use any extended | ||
| features released by later standards. | ||
|
|
||
| * Newlines must remain unix-style for older compilers' sake. | ||
|
|
||
| * Comments must be written in the old-style `/* unnested C-fashion */` | ||
|
|
||
| * Try to keep line lengths below 80 columns and formatted as the existing code. | ||
| There is a `.clang-format` in the repository that can be used to run the | ||
| automated code formatter as such: `clang-format -i */*.c */*.h */*/*.c */*/*.h` |

| This is a feature and bugfix release. | ||
| This is a maintenance and bugfix release. | ||
|
|
||
| Features: | ||
|
|
||
| * When using `ARES_OPT_EVENT_THREAD`, automatically reload system configuration | ||
| when network conditions change. [PR #759](https://github.com/c-ares/c-ares/pull/759) | ||
| * Apple: reimplement DNS configuration reading to more accurately pull DNS | ||
| settings. [PR #750](https://github.com/c-ares/c-ares/pull/750) | ||
| * Add observability into DNS server health via a server state callback, invoked | ||
| whenever a query finishes. [PR #744](https://github.com/c-ares/c-ares/pull/744) | ||
| * Add server failover retry behavior, where failed servers are retried with | ||
| small probability after a minimum delay. [PR #731](https://github.com/c-ares/c-ares/pull/731) | ||
| * Basic support for SIG RR record (RFC 2931 / RFC 2535) [PR #773](https://github.com/c-ares/c-ares/pull/773) | ||
|
|
||
| Changes: | ||
|
|
||
| * Mark `ares_channel_t *` as const in more places in the public API. [PR #758](https://github.com/c-ares/c-ares/pull/758) | ||
| * Validation that DNS strings can only consist of printable ascii characters | ||
| otherwise will trigger a parse failure. | ||
| [75de16c](https://github.com/c-ares/c-ares/commit/75de16c) and | ||
| [40fb125](https://github.com/c-ares/c-ares/commit/40fb125) | ||
| * Windows: use `GetTickCount64()` for a monotonic timer that does not wrap. [1dff8f6](https://github.com/c-ares/c-ares/commit/1dff8f6) | ||
|
|
||
| Bugfixes: | ||
|
|
||
| * Due to a logic flaw dns name compression writing was not properly implemented | ||
| which would result in the name prefix not being written for a partial match. | ||
| This could cause issues in various record types such as MX records when using | ||
| the deprecated API. Regression introduced in 1.28.0. [Issue #757](https://github.com/c-ares/c-ares/issues/757) | ||
| * Revert OpenBSD `SOCK_DNS` flag, it doesn't do what the docs say it does and | ||
| causes c-ares to become non-functional. [PR #754](https://github.com/c-ares/c-ares/pull/754) | ||
| * `ares_getnameinfo()`: loosen validation on `salen` parameter. [Issue #752](https://github.com/c-ares/c-ares/issues/752) | ||
| * cmake: Android requires C99. [PR #748](https://github.com/c-ares/c-ares/pull/748) | ||
| * `ares_queue_wait_empty()` does not honor timeout_ms >= 0. [Issue #742](https://github.com/c-ares/c-ares/pull/742) | ||
| * QueryCache: Fix issue where purging on server changes wasn't working. [a6c8fe6](https://github.com/c-ares/c-ares/commit/a6c8fe6) | ||
| * Windows: Fix Y2K38 issue by creating our own `ares_timeval_t` datatype. [PR #772](https://github.com/c-ares/c-ares/pull/772) | ||
| * Fix packaging issue affecting MacOS due to a missing header. [55afad6](https://github.com/c-ares/c-ares/commit/55afad6) | ||
| * MacOS: Fix UBSAN warnings that are likely meaningless due to alignment issues | ||
| in new MacOS config reader. | ||
| * Android: arm 32bit build failure due to missing symbol. [d1722e6](https://github.com/c-ares/c-ares/commit/d1722e6) | ||
