memory leak

[polomsky]

Each call of validate function will consume about 16MB! of array buffer memory. Node 18.

const SAMLValidator = require('@authenio/samlify-node-xmllint');

const XML = `<samlp:AuthnRequest xmlns:samlp="urn:oasis:names:tc:SAML:2.0:protocol"
    ID="aaf23196-1773-2113-474a-fe114412ab72"
    Version="2.0"
    IssueInstant="2004-12-05T09:21:59Z">
</samlp:AuthnRequest>`;

console.log(process.memoryUsage());
SAMLValidator.validate(XML);
console.log(process.memoryUsage());
SAMLValidator.validate(XML);
console.log(process.memoryUsage());

Memory before call:

{
  rss: 41086976,
  heapTotal: 14307328,
  heapUsed: 9071328,
  external: 406411,
  arrayBuffers: 16610
}

Memory after 2 calls:

{
  rss: 58294272,
  heapTotal: 18771968,
  heapUsed: 13314016,
  external: 34080083,
  arrayBuffers: 33654784
