Performance (vladan)

Blog posts:

• Mike Hommey: Efficiency of incremental builds on inbound + Testing shared cache on try
• Irving Reid: Eliminating the add-on compatibility check dialog during startup
• David Teller: Shutting down things asynchronously
• Mark Reid: Recent Telemetry data outages

Seceng (mmc)

<Read Only>

• TLS False Start, a performance optimization for TLS connections, is now enabled in Firefox 28 Beta and later. This optimization is only enabled for sites that use non-RC4 TLS_ECDHE_*/TLS_DHE_* cipher suites and which support the NPN extension. This includes Twitter, Google, and CloudFlare-hosted servers. There is some compatibility risk to this feature, though we believe we have mitigated all of it with the aforementioned restrictions. Please report any compatibility issues in the "Core :: Security: PSM" component ASAP. bug 942729
• insanity::pkix, the new certificate verification library replacing NSS's certificate verification, landed, pref'd-off (security.use_insanity_verification=false). It is expected to be enabled in a couple of weeks, after OCSP support is added and more testing is done. This was also uplifted to Aurora 29 to make it easier for Certificate Authorities to test it one release before it is enabled. If you don't care about your own HTTPS security and you play with this, please report any issues, particularly compatibility issues, in the "Core :: Security: PSM" component ASAP. bug 878932
• New certificate verification logic for signed packaged apps, based on insanity::pkix, landed in Nightly 30 and will probably be uplifted to Aurora 29 later this week. This enables (will enable, after some non-cert-related issues are resolved) packaged apps from Mozilla Marketplace to be installed in Desktop Firefox. bug 896620
• Some cases where we were doing unnecessary OCSP fetching, potentially causing main-thread I/O and other badness, were fixed for Firefox 28 and later. You shouldn't notice anything with these changes, but Firefox is getting faster in this respect. bug 950129, bug 950240.

Quality Programs

(An opportunity to hear about status with the various quality programs that do not have a formal team structure.)

MemShrink (njn)

• Michael Wu implemented VolatileBuffer, a new class that lets us use volatile memory on OSes that support it, e.g. ashmem on Android.

Roundtable

(Comments and questions that arise during the course of the meeting or otherwise do not have a section.)

<Read only beyond this point>

Mailing List Threads

(Threads that are likely to be of interest to engineering from various mailing lists.)

Good Reads

(Links to blog posts, books, videos, etc. that you think will be of interest to others.)
