Modernize standard library includes

2024-02-20T12:49:04Z

This was automated with sed and git-clang-format, and then I had to fix up the top of policy.cc by hand as git-clang-format accidentally indented it by two spaces.

Improve and test distclean implementation

2024-01-03T13:53:09Z

The implementation as-is as various smaller/esoteric bugs and inconsistencies like apt-get not supporting them, the option -s being supported in code but not accepted on the command line, the regex not escaping the dot before the file extension and exposing more implementation details to public headers than we actually need. Also comes with a small test case to ensure it actually works. References: bd7c126e3fb1b94e76e0e632c657cea854586844

Add 'dist-clean' command to remove packages and list files

2023-11-22T10:05:28Z

We assume all files in the 'listsdir' are candidates. Keep only files ending with Release, Release.gpg, and InRelease. Closes: #959093

Avoid comparison of integers of different signedness for ETA

typecast time_t and suseconds_t from std::chrono

2022-09-17T03:07:40Z

This fixes build on some architectures like mips progress.cc:125:31: error: non-constant-expression cannot be narrowed from type 'std::chrono::duration::rep' (aka 'long long') to '__time_t' (aka 'long') in initializer list [-Wc++11-narrowing] struct timeval NowTime = { Now_sec.count(), Now_usec.count() }; Signed-off-by: Khem Raj

Improve error handling of cycling delayed queues

2021-09-06T14:51:27Z

When an item has been delayed and the queue is cycled to start it, we did not properly report an error from the cycling, and we would then fail in the assert(), causing all errors to be lost. Propagate the error instead and make the assert a warning.

Properly convert PulseInterval to timeval

2021-07-28T11:08:35Z

Fix the typo, and use the helper function to convert it, so we do not end up with 5 seconds encoded as 0s and 5*10^6 microseconds.

Convert to monotonic clock

2021-07-28T11:08:35Z

This yields more accurate delays and avoids issues with clock skew.

acquire: Automatically reduce select() timeout as needed

2021-07-28T11:08:32Z

If there is an item with fetchAfter at the top of a queue, reduce sleep() timeout so we can detect it and start it, by calling Cycle() on the queue in the next iteration. For some reasons we have to call select() with a 0s timeout if we just marked an item as ready. Oh well. Previous versions of this patch only called global Bump() after a timeout from select(); this was unfortunately incorrect - it meant that we never bumped a queue that did not start yet while other queues were running, potentially significantly delaying retries.

Implement exponential delay between retries

2021-07-28T11:04:10Z

Add a new Item field called FetchAfter, which determines the earliest time the item should be fetched at. Adjust insertion into queue to take it into account alongside priority, and only fill pipelines with items that are ready.
