SeaMonkey Meeting Details


  • Who's taking minutes? -> frg
  • Nominees for Friends of the Fish Tank:
    • nthomas for helping out ewong with releng stuff

Action Items

(who needs to do what that hasn't been recorded in a bug) We should assign people to the open items.



  • Mozilla plans to check in l20n. Unclear what this means for comm-central and the current l10n build configs. Needs to be monitored.
    • bug 1107635 - Rewrite build system l10n repack rules from Makefile rules into a Python script might also affect a timely l10n repacks but there has been no movement in it for some time.
    • bug 1372167 - Unify l10n.ini and into a single (python-independent) format for comm-central apps has now been checked in. There are still parts missing in toolkit but this might change the l10n build system again.
  • Google API key for Safe Browsing V2, V4 and Geolocation. Ewong/Callek about getting it loaded onto the build machines.
    • Per bug 903439#c10, ewong confirmed that he has the Google API key. Safe Browsing keys are on the builders according to ewong. The build config changes need to be revised.
    • The key is needed for Safe Browsing V4 currently in Nightly. The V4 lists will not update without it. V2 list updates will be throttled.
    • frg has the location and name of the key and will do a mozconfig patch.
  • New council members frg, rsx11m and ewong were already appointed a few weeks ago. IanN will look into a website update now that the project areas were updated.
  • TODO: Add Adrian Kalla to RelEng team. Overall no change as of today.
  • Discussions and planning about the future of SeaMonkey and if we should set up own builders are still going on.
    • For the previous discussions see the last status meettings.
    • ewong is evaluating the cost and specs for an aws based build system.
    • Cross compiling macOS builds is now possible for Firefox under Linux. If this can be made to work for SeaMonkey we won't need OSX builders.
      • OSX builders would only be needed for tests. This can be added at a later stage.
    • We need a jumphost, a buildmaster, a Windows and a Linux slave.
      • A Puppet system for setup and configuration is under evaluation.
      • Costs and if we should do an initial 1 yor 3 year setup are still evaluated.
      • Funding is available.
    • We need to start with a static setup and expand as necessary.
    • The current infrastructure will be decommissioned in less than a year and is already failing.


  • IanN has spoken to mcsmurf about members list. Members mailing-list is ready to be reviewed.
  • IanN SeaMonkey project areas is very outdated. IanN put up a patch for the project areas and asked for review.

Status of the SeaMonkey Buildbot Master and Tree

  • Various Bugs open for building.
    • Both OSX64 builders did go out to lunch. ewong filed bug 1376192. Both came back after reboot, but one of them disappeared again.
    • OSX64: busted due to bug 1260362. Yasm 1.2 needs to be installed. (Ratty: Depends on bug 1257904. How to get traction on this?)
    • Linux64 Nightly: bug 1275215 is still open but Linux is building most of the time.
    • Linux64 build: bug 1275218 is still open but Linux is building most of the time.
    • Windows building is done on the loaner.
    • Various l10n and other bugs bug 1293943 which might also impact the release schedule.
      • CZ langpacks seem to be disabled by default, so that needs to be sorted.
      • DOMi still needs to be sorted.
      • Lightning l10n upload still needs to be sorted.
      • bug 1372167 might help with the l10n issues.
  • [25th June 2017]
    • Tests have been re-enabled to enable us to find out what's busting them. bug 1295826 tracks the fixes for the Testing Infrastructure.
      • All tests are red.
    • All trees:
      • Problems with Mercurial bug 1368956 make check orange w/ hg unknown command "files".
    • [comm-central]:
    • [comm-beta]:
    • [comm-release]:
    • [comm-esr52]:
  • Notes:
    • For reference only: Building with gtk2 has been disabled and can no longer be done starting with Gecko 53 / SeaMonkey 2.50 bug 1278282.
    • Ewong did set up a cron job to do semi regular builds on the loaner machine. The MAC builders can be updated to OSX 10.9. He needs to consult with Callek first about this.
    • Windows nightly trunk builds are only done on the loaner. Migrating our Windows builders to Win2008 R2 will likely never happen.
      • Callek: Regarding the windows systems, sadly no progress yet. I'm hopeful we can get done sooner than later, I'm realistic expecting it won't be any time soon.
    • Langpacks aren't updated when auto-updating SeaMonkey because they aren't uploaded to AMO. The solution requires changes in SeaMonkey RelEng (and possibly AMO).
    • wrt bug 1155011, we already have a Soccoro token. The patches on bug 1155013 require approval and then pushed and the work-around patches backed out.
  • See RelEng page for the RelEng status history.

Release Train

  • SeaMonkey 2.48 will be the next release tracked in bug 1351984 (general beta issues in bug 1328886).
    • ewong has started building 2.48, bug 1376192 is a hard blocker for Mac OSX builds.
    • SEAMONKEY_2_48_BUILD1 is tagged! and some candidate builds are already available
    • Release notes in bug 1336315.
    • Updates from older SeaMonkey versions will not work for 2.48. ewong gave up making this work. We will announce this everywhere and on the project page. This does not affect Linux distributions which do their own builds.
    • l10n problems from 2.46 are still not solved. Extensions again can not be shipped bundled with this release. A removal patch has been checked in. DOMi and cZ tags have nevertheless been updated for a future release.
      • l10n problem is tracked in (bug 1231349).
      • Chatzilla and DOMi repack problems are also tracked in bug 1315552.
      • IanN has locale merge working for Chatzilla and is working on the DOMi repack issues.
      • See also bug 652063 (Enable localized ChatZilla builds).
  • gtk3 will be disabled for 2.48 beta and release builds. It will be enabled for 2.49.1. 2.48 will be the last gtk2 build.
    • There are at least three problems with gtk3 builds which may not be resolved in time (bug 1269145, bug 1267982, bug 1331208).
    • A regression for gtk2 builds since 2.40 has been identified but is limited to certain desktop themes and doesn't seem to affect the most current OS version (bug 1312215).
    • A meta bug for gtk3 compatibility has been created for 2.49.1 and up (bug 1367257)
  • The next release after 2.48 will be 2.49.1 build from the ESR branch. It is tracked in bug 1346939.
    • SeaMonkey 2.49.1 will be build with ALSA support. This has been disabled in Firefox 52 and causes problems for Linux users (see discussion in bug 1345661).
    • Updates for 2.48 are not working. For 2.49.1 updates need to be tested if they are still working:
      • bug 1274722 Add %SYSTEM_CAPABILITIES% to the SeaMonkey app.update.url preference
      • bug 1271761 Add CPU features/detection to update URL
    • bug 1322172 bug 1347857 and bug 1368277 need to be fixed for 2.49.1. All have patches attached and are in review or reviewable so this should not hold up the release.
    • Patches should also pushed to Beta when they go to the ESR52 tree.
  • Discussions if we should match minor version numbers with Firefox are still underway. This would need a coordinated change for either c-c or all trees. All minor versions would be changed and the versions would need to be made available in bugzilla. Lightning version calculation needs to be changed. This will be done at a later date and not for 2.49 ESR.
  • ewong: Suggests the following:
    • Officially release a linux64 build (incl. tests)
      • Start with comm-central trunk.
      • Not entirely sure what is needed to make it official. Need to correspond with Callek.
    • Build an unofficial (contributed build) Win64 build. [akin to the status that Linux64 has now.]
      • Start later with comm-central we need to iron out the build issues, though right now, having just finished a W64 build; but I don't know how the tests are going to work though this will need to wait).
      • Currently tracked by bug 482143.
  • Releases will be done off comm-esr52 and then comm-esr59.
    • Firefox plans removal of non-WebExtension add-ons and full-theme support with Gecko 57 [1].
    • Patches which do not concern Thunderbird could be checked into comm-esr52 (once established) after getting approval too.

Extensions and Plugins Compatibility Tracking

  • SeaMonkey Council is looking into setting up a separate add-ons site for SeaMonkey extensions. This would fix long standing issues we have with AMO.
    • Ratty and IanN will meet with the AMO people to discuss this.
    • Ratty and IanN will meet with the Thunderbird people to discuss this.
    • Progress is slow to non-existent because Ratty is currently absent.
    • [Ratty] Suggests that if we do this, we can also host the Firefox & Thunderbird Add-on Converter for SeaMonkey.
  • Firefox plans removal of non-WebExtension add-ons and full-theme support with Gecko 57 [2].
    • new add-ons other than WebExtensions will no longer be accepted for signing as early as Gecko 53.
    • The add-on sdk will be removed from mozilla code for Firefox 58. Other parts will follow.
  • See Basics page. Please only list current changes here.
  • Firefox & Thunderbird Add-on Converter for SeaMonkey
    This tool goes a little further beyond simply modifying install.rdf - it also identifies a few more other things in the code that are Firefox or Thunderbird specific and attempts to change them. Of course, not all extensions can be ported so easily to SeaMonkey since there's only so much an automated tool like that can do.
    • We are looking for a better(?) home for extension-converter pages, along with a way to track successful and conversion-failed add-ons, and respective integration into SeaMonkey by add-on or manager overlay [3], bug 1145026.
    • Ratty filed bug 1130390 to add a link on to the Firefox & Thunderbird Add-on Converter for SeaMonkey.
  • The AMO Browsing for SeaMonkey extension, which makes AMO pages a lot more SeaMonkey-friendly, is mature. It was developed by LemonJuice (of Add-on Converter fame), and Tonymec, who tested it and now uses it, supports it enthusiastically. The author proposes to add it as a "built-in extension" besides ChatZilla, DOMi and the like. What do you think? (See also Bug 1145026: AMO Add-On-Descriptions: Add link function leading to SeaMonkey add-on-converter and filling URL input pane; the extension actually does much more than the bug's Summary implies: for instance it gets rid of the stupid "You need Firefox 10 or later" popups.
  • The HTML Validator adds HTML validation to SeaMonkey. The Beta version is no more Windows-only: it boasts support for W32/64, L32/64 and Mac 32/64 Universal in a single XPI. It does not officially support trunk builds but in Tonymec's experience it worked with them last year. It offers a choice of validators: Tidy, SGML (same algorithm as the W3C validator but client-side) or both. Caveat: The toolbar button gives no results for HTML5, you need View Source for that. See the developer's site for details.
  • In Gecko 52 obsolete toolkit parts were removed in bug 1312143. This may cause problems with older add-ons when SeaMonkey 2.49 hits the road. The 2.49 release notes should mention it. Chatzilla and DOMi were affected and were fixed.
  • There is a new build variable: MOZ_ALLOW_LEGACY_EXTENSIONS=1. It is currently set to true (1) and has also been put into SeaMonkeys to play it safe.
  • Adblock Plus 2.9 is broken in 2.48 and up. 2.9.1 has speed problems. It is recommended to use 2.8.2 right now.

  • OSX builds can be done with the 10.12 SDK in the future. The SDK is provided in bug 1324892 via tooltool.
  • We need someone to work on porting sync 1.5 over to replace legacy sync code. Frg was distracted by other bugs and tasks and didn't look into it yet.
    See: New Firefox Sync has landed in Firefox Nightly. Tracked in:
    • bug 998807 Sync account creation or device pairing fails with exception in BrowserIDManager.
    • bug 1003434 Add support for about:sync-progress.
    • As an alternative to porting sync setting up a sync 1.1 server might work.
    • Sync 1.1 has been removed from the mozilla source tree. If we want sysnc 1.1 to work we need to fork it.
      • Pro: We control our own sync server and are not left at the mercies of Mozilla the next time they change their sync system.
      • Con: Can't sync with Firefox (unless someone writes a Sync 1.1 client for Firefox).
  • Stalled. Needs a kick:
    • bug 815954 Click-to-Play: Port bug 812562 (click-to-play blocklisted plugins: reshow urlbar notification as with normal click-to-play).
    • bug 476108 GetShortPathNameW fails under some NTFS junctions [patchlove].
  • Current breakages:
  • Mozilla-central bugs that affect us:
    • bug 1298243 'drag/drop: DataTransfer.types is wrong type'. Building SeaMonkey still works but changes probably need to be ported.
    • bug 1276739 'replace list.txt with a region-aware JSON file format to allow different search configs...'. Regressions for SeaMonkey are tracked in bug 1300198.
      • bug 1300198 Move list.txt over to JSON once bug 1276739 is in.
        • This will likely break search engines and needs to be looked at.
    • A lot of these bugs are due to mozilla-central switching from synchronous APIs to Asynchronous APIs.
    • The C++ downloads manager backend nsIDownloadManager is being decommissioned. Firefox and Thunderbird have migrated to jsdownloads. Its going away in
    • bug 825588 Asynchronous JavaScript API for downloads and bug 851471 Decommission nsIDownloadManager. Tracked in:
      • bug 888915 Move SeaMonkey to the new JavaScript API for downloads when nsIDownloadManager is decommissioned. Needs further work.
    • bug 1378089 Figure out what to do with bookmarks transactions. Probably needs a lot of work after SeaMonkey 2.53.
  • [adriank] would like to drop DOMi or at least not bundling it with release builds in bug 1273222. Open for discussion.
  • [rsx11m] did open bug bug 1305902 for certificate pinning. Discussion if it should be enabled for SeaMonkey is still underway. Callek commented in the bug.
  • Nightly and Aurora updates are broken. bug 1321131 might be the cause. Aurora users need to be migrated to another channel if possible.

Feature List, Planning

Bug statistics for the last two (full) weeks: 19 new, 4 fixed, 3 triaged.

  • low triaging effort, average number of new bugs filed.

Open reviews/flags: 36 review 5 super-review 1 ui-review 12 feedback

  • See Feature List page for major wanted/needed features.
  • TODO:
    • Encrypted Media Extensions / Digital Rights Management
      • bug 1127784 added a preference and UI to enable/disable playback of Encrypted Media Extensions, with UI seen in non-release builds only
      • More work appears to be needed to download necessary 3rd-party Content Decryption Modules, some UI can probably be ported from Firefox
  • Mozilla wants to Move Thunderbird off MoCo infrastructure and onto their own, which will likely affect SeaMonkey as well
  • Fundamental core features Firefox/Mozilla plans to remove:
  • Rainer does a Coffee-Mug-Competition. Please let any developers you know to it and post a big Help wanted! sign.
  • SeaMonkey Composer is outdated. Ratty thinks that using backports or parts of KompoZer [4] might solve some of the problems.
  • x64 Linux and for the first time x64 Windows builds will be made official as soon as possible.
    • Unofficial Linux builds just need to be declared official.
    • Providing Windows x64 builds is tracked in bug 482143.
  • The website and wiki are outdated. InvisibleSmiley no longer maintains the website. For 2.46 the website was updated but it still needs work.
  • frg suggested asking for donations in a future release. Probably during startup or more prominently on the website.
  • frg suggested a tabbrowser.xml overhaul because it's becoming harder to backport fixes from Firefox.
    • IanN suggests doing small patches which are easier to review.
  • There are reports that the PayPal donation on the website doesn't work for USD. It seems the amount is converted to Euro (probably correct if it is a German account).

Roundtable - Personal Status Updates

IanN generally will handle more complex review requests. Ratty is currently absent. frg, rsx11m, stefanh and ewong can also do reviews in their areas of expertise. For bigger changes and branch approvals outside of the build system IanN needs to be involved

Status Updates from developers - what are you working on, what's the progress, any other comments? (feel free to add yourself to the list if your name is missing and you have interesting status).




Waiting for review or feedback:

  • bug 1322172 Security relevant. Needed for 2.49.1.
  • bug 1336315 (SM248-RELNOTE) Create/Update 2.48 Release Notes
  • bug 1370314 SeaMonkey 06/2017 installer rollup. Waiting for feedback what should be taken. Probably not much more right now. Took some parts to other bugs.
  • bug 1373374 SeaMonkey is incorrectly enclosed in quotation marks in Set Default Programs dialog.
  • bug 1373375 SeaMonkey extensions and themes are flagged as legacy in add-ons manager. Missed a pref. Needs a new review.
  • bug 1374094 Update debugQA extension for older SeaMonkey versions. Need to move a function from editor into the patch and retest it.
  • bug 1374708 Style and color quotes in messages.
  • bug 1377659 Port bug 492329 to SM: The error message for an expired newsgroup article is not displayed.

Working on:

  • The daily 2.53a1 breakage.
  • bug 521861 After creating news account through clicking news URL Account Wizard is broken. On the backburner.
  • bug 1256724 Update The Data Manager, and the Cookie Viewer so as to treat backspace and delete equivalently on Mac OS X. Took over the bug. Need to figure out some backspace problems in cookieviewer
  • bug 1282227 Port Bug 1071880 and Bug 1142937 to SeaMonkey: Notifiy users of slow addons. Unable to test. Either not working or I am missing something. On the backburner and without input from Ratty I need to look at it later.
  • bug 1293618 "Clear History from Private Data" completely broken (only test part left). A little on the backburner.
  • bug 1296850 Show standard loading indicator images in tab when busy or progress attribute are set. On the backburner. Asked someone who wants to help out to look at the icons.
  • bug 1326377 Media view 'Save As ...' for embedded(?) picture fails. Need to find out how to get the private window status.
  • bug 1379368 About pages lost the proper styling. Have a WIP fix I need to clean up. Also affects Modern so need to fix this too.
  • bug 1379369 Port bug 1364016 "Have _openURIInNewTab() provide the correct triggeringPrincipal" to SeaMonkey. Have a WIP fix but need to clean it up.
  • Trying to clean up the shipped extensions build process so that they can be included / disabled via Halfway done. No bug yet.

On the list (the actual one in Brain 1.0 is longer and gets longer every day)

  • Followup for bug 888915 Convert SeaMonkey Downloads Manager to Downloads.jsm.


  • No time for Sync at the moment.
  • Putting updated debugQA and DOMi extensions on AMO. Started with debugQA and noticed that it was no longer compatible with older versions. Finalizing the bugs now.

Other things on my mind:

  • --enable-optimize=-O2 should be used for Windows release builds. Linux gcc --enable-optimize optimizes for speed. With VS2015 it optimizes for size. Resulting O2 Windows build feels a lot snappier. Will ask glandium about it.


Rainer Bielefeld
