So fixing it the nssPKIObjectCollection to use hash tables — one hashed on the object uid and one on the instance (token/handle) — will be a very good start. From discussion on IRC it looks like you're making good progress on that. But we still end up with the rather bizarre situation that things lie PK11_FindCertsFromEmailAddress() are invoking NSSTrustDomain_TraverseCertificates() with their own callback (e.g. FindCertsEmailCallback()) but we still end up building up this huge nssPKIObjectCollection of *all* the certs that exist anywhere, before we start to filter it down to only the ones we're actually interested in. So your hash tables fixes are great, and they'll fix PK11_ListCerts() to run in a sane amount of time. But I still find myself wondering why the PK11_FindCertsFrom*() functions even *noticed* this issue. We should apply the filter *before* building up the results in a collection, surely? -- David WoodhouseOpen Source Technology Centre david.woodho...@intel.com Intel Corporation smime.p7s Description: S/MIME cryptographic signature -- dev-tech-crypto mailing list dev-tech-crypto@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-tech-crypto
Optimizing NSSTrustDomain_TraverseCertificates() of nss package
Hi all, I've currently been working on optimizing the nss package functions like NSSTrustDomain_TraverseCertificates() which can be seen at https://dxr.mozilla.org/mozilla-central/source/security/nss/lib/pki/trustdomain.c?from=NSSTrustDomain_TraverseCertificates#988 and nssPKIObjectCollection_AddInstances() as can be seen at https://dxr.mozilla.org/mozilla-central/source/security/nss/lib/pki/pkibase.c?case=true=nssPKIObjectCollection_AddInstances#827 . Currently the nss package uses a circular linked list to store certs. Hence the following functions give a very bad performance of O(n*n) for adding instances of certs into the list. Each addition first consists of an addition to the linked list O(n) followed by a check for duplicates which is performed by the function add_object_instance. I'm currently working to migrate the storage of certs to a hash table rather than a linked list which provides lookups at O(1) rather than the present lookup of O(n). The details of this behavior can be found in https://bugzilla.mozilla.org/show_bug.cgi?id=1253211 Any alternate suggestions to improve and optimize the behavior are welcomed. -- dev-tech-crypto mailing list dev-tech-crypto@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-tech-crypto
