Gary

Bug 1415115 - PERMA-FAIL | accessible/tests/mochitest/events/docload/test_docload_root.html | Test timed out.

Junior

Bug 1415120 - Crash in mozilla::detail::RunnableFunction<nsCookieService::RebuildCorruptDB(DBState*)::<lambda()>::<lambda()> >::Run

  • r?

  • Root cause: cookie requests during rebuilding and we close the all the connections. The request is trying to connect a db which is renamed and not loaded.

  • solution: access the cookies from hashtable. drop all the db operations because we will backport them to new db anyway. Bug 1413839 - Add telemetry to probe how close we’re going to block main thread

  • r? Bug 1416985 - MOZ_SQLITE_COOKIES_OLD_SCHEMA seems bogus for unreasonable many people using cookies.txt

  • WIP

Amy

Bug 1357676 - Increase cookie count limits to match Chrome’s

  • Got r- from Josh

  • Have to discuss the new batch eviction algorithm to Josh and Martin. Bug 1413512 - Get telemetry on how often we see HTTP(S) -> FTP redirects

  • Start to implement this bug. Bug 1414206 - doesnt logout properly in firefox57

  • Reporter used the wrong setting.

Kershaw

Bug 1413999 - Add support for Server-Timing HTTP trailing header

*- Almost finish the parser and test case

Bug 1416623 - Skeletal code for socket process

*- WIP uploaded *- Basic setup for new process, such as new process type, init XPCOM, etc. *- TODO:

  • Try to create UDPSocket in socket process
  • sandboxing

SC

[Socket Process]

  • study "Endpoint" mechanism for IPC between child process (reference: bug wwwwww)

  • Prototyping

  • design interface and flow for UDPSocket

  • https://docs.google.com/presentation/d/12Jg2eXT7nne2G8MtS3E2p7yRGaQJrvXg8iiQOhYggFU/edit#slide=id.g286761667d_0_0

  • create project wiki page https://wiki.mozilla.org/Necko:_Sandboxing_TCP/UDP_socket_in_a_separate_process

  • discuss sandboxing design with @pauljt

  • put protocol code in separate process is better

  • try not have plain TCP/UDP IPC interface, to have better control on the network usage [Others]

  • Bug 1390708 - .hqx files are all corrupted when downloaded with FF unless going through SAVE AS...

  • remove BinHex stream converter support, landed on m-c (firefox 59)

  • Bug 1416879 - Crash in mozilla::net::HttpChannelParentListener::OnDataAvailable

  • parent ODA called during channel suspension for diversion, might be timing issue caused by intercept stream listener
