libc/tests: add stdbit test framework and unit tests

2025-11-30T19:21:52+00:00

This adds unit tests for all 70 functions in .

I'm sorry for the test framework, but it makes it so I don't
have to write 70 unit tests by hand.

strptime: Fix day-of-week calculation.

2024-12-09T12:38:22+00:00

The day-of-week calculation used the raw year value without adjusting
for TM_YEAR_BASE, so it was off by one for 300 years out of every 400;
it just happened to be correct for 1901 through 2000.  It also used a
loop where a simple addition would have sufficed.

While here, simplify our version of Gauss's algorithm, and document
that we assume the Gregorian calendar.

libc: tests: add testing infrastructure for _FORTIFY_SOURCE

2024-07-13T05:16:23+00:00

The _FORTIFY_SOURCE tests will be generated by a lua script to avoid a
lot of redundancy in writing these tests.  For each function that we're
fortifying, the plan is to test at least the following three scenarios:

 - Writing up to one byte before the end of the buffer,
 - Writing up to the end of the buffer,
 - Writing one byte past the end of the buffer

The buffer is shoved into a struct on the stack to guarantee a stack
layout in which we have a valid byte after the buffer so that level 2
fortification will trip and we can have confidence that it wasn't some
other stack/memory protection instead.

The generated tests are divided roughly into which header we're
attributing them to so that we can parallelize the build -- the full set
is a bit over 9000 lines of C and takes 11s to build on the hardware
that I'm testing on if it's a single monolothic file.

issues fixed recently, and disabling the failing ones (mostly due to TZ

iconvctl(3): remove superfluous NULL pointer tests

2016-05-14T00:35:35+00:00

convname and dst are guaranteed to be non-NULL by iconv_open(3).
src is an array. Remove these tests for NULL pointers.
While I'm here, eliminate a strlcpy with a correct but suspicious-looking
calculation for the third parameter (i.e. not a simple sizeof).
Compare the strings in-place instead of copying.
