Moved posix_result from file.c to errno2result.[ch], for use by multiple source files. We may want to generalize this as part of the libisc API, but with a better name. 2000-05-11 11:09:30 -04:00			`/*`

Update the copyright information in all files in the repository This commit converts the license handling to adhere to the REUSE specification. It specifically: 1. Adds used licnses to LICENSES/ directory 2. Add "isc" template for adding the copyright boilerplate 3. Changes all source files to include copyright and SPDX license header, this includes all the C sources, documentation, zone files, configuration files. There are notes in the doc/dev/copyrights file on how to add correct headers to the new files. 4. Handle the rest that can't be modified via .reuse/dep5 file. The binary (or otherwise unmodifiable) files could have license places next to them in <foo>.license file, but this would lead to cluttered repository and most of the files handled in the .reuse/dep5 file are system test files. 2021-06-03 02:37:05 -04:00			`*`

Use #pragma once as header guards Unify the header guard style and replace the inconsistent include guards with #pragma once. The #pragma once is widely and very well supported in all compilers that BIND 9 supports, and #pragma once was already in use in several new or refactored headers. Using simpler method will also allow us to automate header guard checks as this is simpler to programatically check. For reference, here are the reasons for the change taken from Wikipedia[1]: > In the C and C++ programming languages, #pragma once is a non-standard > but widely supported preprocessor directive designed to cause the > current source file to be included only once in a single compilation. > > Thus, #pragma once serves the same purpose as include guards, but with > several advantages, including: less code, avoidance of name clashes, > and sometimes improvement in compilation speed. On the other hand, > #pragma once is not necessarily available in all compilers and its > implementation is tricky and might not always be reliable. 1. https://en.wikipedia.org/wiki/Pragma_once 2021-10-05 10:49:47 -04:00			`#pragma once`

[master] fix dyndb issues; isc_errno_toresult() 4445. [cleanup] isc_errno_toresult() can now be used to call the formerly private function isc__errno2result(). [RT #43050] 4444. [bug] Fixed some issues related to dyndb: A bug caused braces to be omitted when passing configuration text from named.conf to a dyndb driver, and there was a use-after-free in the sample dyndb driver. [RT #43050] Patch for dyndb driver submitted by Petr Spacek at Red Hat. 2016-08-17 14:22:09 -04:00			`unsigned int line);`
