test: Check that apt-ftparchive handles deep paths

2024-10-15T13:22:26Z

This checks for the previous boundaries for path sizes; but we also added a check for many files in a directory, limited to 4096. Sadly the directory check did not fail with the old code either, it's hard to actually get it to fail correctly.

test framework: Improve valgrind support

2024-10-15T13:10:34Z

Add support for testing apt-ftparchive, set valgrind to quiet such that we can check program output, and pass --error-exitcode=7 to get an (should be unused) magic error code if it detects errors.

ftparchive: contents: Avoid exponential complexity and overflows

2024-10-07T14:17:32Z

Wstored directory entries as a binary tree, but we did not balance it, leading to exponential complexity on insertion and potentially exponential levels of stack recursion in DoPrint(), causing overflows. Simply use an std::set storing pairs of (path, package) instead, this is very simple, and handles aspects such as ordering or the same package appearing multiple times correctly. Iteration becomes a bit tricky: After seeing (file1, pkg1) when we see (file1, pkg2) we need to append pkg2 to the current line; once we see (file2, anything), we need write out the line and start a new one. For memory optimization, we use a new class StringInBlock to handle the block-managed C strings generated by Mystrdup() in a type-safe manner. This ensures proper lifetime of objects and no accidental conversions to std::string. This saves a significant amount of space (a pair of std::string is 64-byte large; a pair of pointers is 16 byte large, a 48 byte saving per entry); reproducing the Contents file of Ubuntu 24.10, using straight-forward std::string resulted in GB of memory usage, whereas the C-style string only uses 1.35 GB. As a side effect of the patch we also remove arbitrary 1024-byte buffer sizes. There also is a change in output: The package names are now sorted alphabetically, instead of being in visit order.

ftparchive: Mystrdup: Add safety check and bump buffer size

2024-10-07T14:02:06Z

Add a safety check to ensure that the block were are allocating actually fits the string we want to write. If it doesn't, abort the program. While we are here, bump the buffer size from 40 KiB to 4 MiB, because why bother with smaller buffers.
