Bump CMAKE_CXX_STANDARD to 23 and fix code

2025-05-25T09:21:24Z

ftparchive/contents.h failed with operator< defined only, so define operator<=> instead. The operator and FileCopyType constructor both had a warning about not throwing and adding a noexcept, so add one

Drop usage of macro APT_OVERRIDE for simple override

2025-01-05T22:16:08Z

We were rather inconsistent in using it and as our public headers contain deduction guides (a c++17 feature) it seems silly to try to hide a c++11 feature in a macro, so lets stop this charade and drop the macro and while we are changing all these lines lets apply [[nodiscard]] (another c++17 feature) and other suggestions from clang-tidy and formatting for a little more consistency.

Merge branch 'fix/partialfilemirror' into 'main'

2024-11-22T16:12:34Z

Support uncompressed indexes from partial file:/ mirrors See merge request apt-team/apt!235

Look at non by-hash paths in copy and file methods

2024-11-22T12:40:10Z

Ideally copy and file mirrors would support by-hash as well, but its harder to setup and maintain especially if you want to cache an online mirror who has by-hash enabled. We can avoid unneeded roundtrips (in the best case) and entire cache misses (in the usual worst case) by "just" telling methods that the URI we passed it has the requested file perhaps also in other paths. This is done in pseudo-relative paths as we would otherwise need to teach redirection code to rewrite those URIs as well. A method like http can easily ignore this value and await explicit instructions to look at that file, but inspecting the path in local sources via file or copy is (comparatively) free, so we just do it immediately. If that ends up being the wrong version of the file as by-hash would have protected us from we are in this feature branch now falling back to other mirrors which are like the ones online and in support of by-hash.

Tag hidden acquire classes as final for devirtualization

2024-11-22T12:13:25Z

gcc reports `warning: Declaring type ‘class X’ final would enable devirtualization of Y calls [-Wsuggest-final-types]`. Not that this would massively improve performance, but it shouldn't hurt telling the compiler what is obvious for a human.

Implement encoded URI handling in all methods

2020-12-18T18:31:19Z

Every method opts in to getting the encoded URI passed along while keeping compat in case we are operated by an older acquire system. Effectively this is just a change for the http-based methods as the others just decode the URI as they work with files directly.

Sandbox methods with seccomp-BPF; except cdrom, gpgv, rsh

2017-10-22T21:38:31Z

This reduces the number of syscalls to about 140 from about 350 or so, significantly reducing security risks. Also change prepare-release to ignore the architecture lists in the build dependencies when generating the build-depends package for travis. We might want to clean up things a bit more and/or move it somewhere else.

Reformat and sort all includes with clang-format

2017-07-12T11:57:51Z

This makes it easier to see which headers includes what. The changes were done by running git grep -l '#\s*include' \ | grep -E '.(cc|h)$' \ | xargs sed -i -E 's/(^\s*)#(\s*)include/\1#\2 include/' To modify all include lines by adding a space, and then running ./git-clang-format.sh.

don't change owner/perms/times through file:// symlinks

2016-07-06T00:25:51Z

If we have files in partial/ from a previous invocation or similar such those could be symlinks created by file:// sources. The code is expecting only real files through and happily changes owner, modification times and permission on the file the symlink points to which tend to be files we have no business in touching in this way. Permissions of symlinks shouldn't be changed, changing owner is usually pointless to, but just to be sure we pick the easy way out and use lchown, check for symlinks before chmod/utimes.
