static VALUE
bs_compile_option_crc32_set(VALUE self, VALUE crc32_v)
{
  if (!RB_TYPE_P(crc32_v, T_BIGNUM) && !RB_TYPE_P(crc32_v, T_FIXNUM)) {
    Check_Type(crc32_v, T_FIXNUM);
  }
  current_compile_option_crc32 = NUM2UINT(crc32_v);
  return Qnil;
}

Bootsnap’s ruby code registers a hook that notifies us via this function when compile_option changes. These changes invalidate all existing caches.

Note that on 32-bit platforms, a CRC32 can’t be represented in a Fixnum, but can be represented by a uint.

coverage_running? ()

static VALUE
bs_rb_coverage_running(VALUE self)
{
  VALUE cov = rb_get_coverages();
  return RTEST(cov) ? Qtrue : Qfalse;
}

fetch (p1, p2, p3, p4)

Source

static VALUE
bs_rb_fetch(VALUE self, VALUE cachedir_v, VALUE path_v, VALUE handler, VALUE args)
{
  FilePathValue(path_v);

  Check_Type(cachedir_v, T_STRING);
  Check_Type(path_v, T_STRING);

  if (RSTRING_LEN(cachedir_v) > MAX_CACHEDIR_SIZE) {
    rb_raise(rb_eArgError, "cachedir too long");
  }

  char * cachedir = RSTRING_PTR(cachedir_v);
  char * path     = RSTRING_PTR(path_v);
  char cache_path[MAX_CACHEPATH_SIZE];

  /* generate cache path to cache_path */
  bs_cache_path(cachedir, path_v, &cache_path);

  return bs_fetch(path, path_v, cache_path, handler, args);
}

Entrypoint for Bootsnap::CompileCache::Native.fetch. The real work is done in bs_fetch; this function just performs some basic typechecks and conversions on the ruby VALUE arguments before passing them along.

precompile (p1, p2, p3)

Source

static VALUE
bs_rb_precompile(VALUE self, VALUE cachedir_v, VALUE path_v, VALUE handler)
{
  FilePathValue(path_v);

  Check_Type(cachedir_v, T_STRING);
  Check_Type(path_v, T_STRING);

  if (RSTRING_LEN(cachedir_v) > MAX_CACHEDIR_SIZE) {
    rb_raise(rb_eArgError, "cachedir too long");
  }

  char * cachedir = RSTRING_PTR(cachedir_v);
  char * path     = RSTRING_PTR(path_v);
  char cache_path[MAX_CACHEPATH_SIZE];

  /* generate cache path to cache_path */
  bs_cache_path(cachedir, path_v, &cache_path);

  return bs_precompile(path, path_v, cache_path, handler);
}

Entrypoint for Bootsnap::CompileCache::Native.precompile. Similar to fetch, but it only generate the cache if missing and doesn’t return the content.

readonly= (p1)

static VALUE
bs_readonly_set(VALUE self, VALUE enabled)
{
  readonly = RTEST(enabled);
  return enabled;
}
