Damien George ede8a0235b py/vstr: Raise a RuntimeError if fixed vstr buffer overflows. Current users of fixed vstr buffers (building file paths) assume that there is no overflow and do not check for overflow after building the vstr. This has the potential to lead to NULL pointer dereferences (when vstr_null_terminated_str returns NULL because it can't allocate RAM for the terminating byte) and stat'ing and loading invalid path names (due to the path being truncated). The safest and simplest thing to do in these cases is just raise an exception if a write goes beyond the end of a fixed vstr buffer, which is what this patch does. It also simplifies the vstr code.		7 years ago

README

This directory contains tests for various functionality areas of MicroPython.
To run all stable tests, run "run-tests" script in this directory.

Tests of capabilities not supported on all platforms should be written
to check for the capability being present. If it is not, the test
should merely output 'SKIP' followed by the line terminator, and call
sys.exit() to raise SystemExit, instead of attempting to test the
missing capability. The testing framework (run-tests in this
directory, test_main.c in qemu_arm) recognizes this as a skipped test.

There are a few features for which this mechanism cannot be used to
condition a test. The run-tests script uses small scripts in the
feature_check directory to check whether each such feature is present,
and skips the relevant tests if not.

When creating new tests, anything that relies on float support should go in the
float/ subdirectory.  Anything that relies on import x, where x is not a built-in
module, should go in the import/ subdirectory.
