Compared with what Pale Moon had for Solaris originally, this is mostly the same zero point I started patching from, but I've made the following changes here after reviewing all this initial code I never looked at closely before.
1. In package-manifest.in for both Basilisk and Pale Moon, I've made the SPARC code for libfreebl not interefere with the x86 code, use the proper build flags, and also updated it to allow a SPARC64 build which is more likely to be used than the 32-bit SPARC code we had there.
2. See Mozilla bug #832272 and the old rules.mk patch from around Firefox 30 in oracle/solaris-userland. I believe they screwed up NSINSTALL on Solaris when they were trying to streamline the NSS buildsystem, because they started having unexplained issues with it around that time after Firefox 22 that they never properly resolved until Mozilla began building NSS with gyp files. I'm actually not even sure how relevant the thing they broke actually is to Solaris at this point, bug 665509 is so old it predates Firefox itself and goes back to the Mozilla suite days. I believe $(INSTALL) -t was wrong, and they meant $(NSINSTALL) -t because that makes more sense and is closer to what was there originally. It's what they have for WINNT, and it's possible a fix more like that could serve for Solaris as well. Alternatively, we could get rid of all these half-broken Makefiles and start building NSS with gyp files like Mozilla did.
3. I've completely cut out support for the Sun compiler and taken into account the reality that everyone builds Firefox (and therefore its forks) with GCC now on Solaris. This alone helped clean up a lot of the uglier parts of the code.
4. I've updated all remaining SOLARIS build flags to the newer XP_SOLARIS, because the SOLARIS flag is no longer set when building Solaris.
5. I've confirmed the workaround in gtxFontconfigFonts.cpp is no longer necessary. The Solaris people got impatient about implementing a half-baked patch for a fontconfig feature that wasn't ready yet back in 2009, and somehow convinced Mozilla to patch their software to work around it when really they should have just fixed or removed their broken fontconfig patch. The feature they wanted has since been implemented properly, and no version of Solaris still uses the broken patch that required this fix. If anyone had ever properly audited this code, it would have been removed a long time ago.
List of relevant patches applied:
1398537 part 2 - [css-multicol] Implement percentages for 'column-gap' (Gecko part).
1434478 part 1 - [css-grid] Stop back-computing percentage grid gaps when the percentage basis is indefinite. Treat them as zero sized instead.
1434478 part 2 - Stop back-computing percentage padding/margin when the percentage basis is indefinite. Treat them as zero sized instead.
1434478 part 3 - Remove IntrinsicISizeOffsetData::hPctPadding/hPctMargin members since they are now unused.
1434478 part 4 - Factor out constants like NS_UNCONSTRAINEDSIZE so they can be used in headers without needing nsIFrame.h (idempotent patch).
1434478 part 5 - Create nsLayoutUtils::ResolveToLength for resolving CSS <length-percentage> (idempotent patch).
1434478 part 6 - Propagate a percentage basis to nsIFrame::IntrinsicISizeOffsets for resolving padding/margin.
This is needed only for CSS Grid since in other cases we're only using IntrinsicISizeOffsets in the inline-axis and the percentage basis is always indefinite for *intrinsic sizing*. When calculating the intrinsic size of grid items in the grid container's block axis however, we do have a definite size for the grid area in the inline-axis and it should be used per: https://drafts.csswg.org/css-grid/#algo-overview "2. Next, the track sizing algorithm resolves the sizes of the grid rows, using the grid column sizes calculated in the previous step." (Percentage padding/margin for grid items is always resolved against the grid area's inline-size nowadays.)
List of relevant patches applied:
1425599 part 15 - [css-grid] Test reference fixes + more tests.
1373678 Part 3: Add line number checks to test_grid_implicit.html.
1416350 - Part 3: Add test to verify line numbers of grids with leading implicit tracks.
1416350 - Part 4: Add a reftest of repeat:auto-fit grids with leading implicit tracks.
1417711 - [css-grid] An abs.pos. grid container child that only covers removed 'auto-fit' tracks should not span to the end padding edge.
1416350 - Part 5: Correct the expected results for grids that have leading implicit tracks.
1418727 part 3 - [css-grid] Reftest updates.
List of relevant patches applied:
1425599 part 1 - [css-grid] Change the track sizing algorithm for spanning items so that it accumulates individual item contributions to the plan by max() rather than incrementing the planned size directly.
Also, fix a bug when copying back the planned limits after updating it for the first span group. It should only copy back track sizes that were actaully spanned by those items, other content-sized tracks' limits should remain at "infinity".
1425599 part 2 - [css-grid] Factor out the min-sizing parts of the track sizing for spanned items to a templated method (idempotent change).
1425599 part 3 - [css-grid] Factor out most of the max-sizing parts of the track sizing for spanned items to a templated method (idempotent change).
1425599 part 4 - [css-grid] Factor out the starting base/limit size to a templated method (idempotent change).
1425599 part 5 - [css-grid] Make CollectGrowable a templated method so that it works with either base/limit sizes (idempotent change).
1425599 part 6 - [css-grid] Make the size distribution methods templated with the intent of merging them in a later patch (idempotent change).
This patch also introduces an eInfinitelyGrowable bit to help get rid of the 'limits' temporary track sizes in the next patch.
1425599 part 7 - [css-grid] Remove the 'limits' copy of track sizes since they are no longer needed (idempotent change).
1425599 part 8 - [css-grid] Factor out the fit-content clamping function from DistributeToTrackLimits and pass it as a param instead (idempotent change).
1425599 part 9 - [css-grid] Merge DistributeToTrackLimits/Bases (idempotent change).
1425599 part 10 - [css-grid] Make MarkExcludedTracks a static method since it doesn't use 'this' (idempotent change).
1425599 part 11 - [css-grid] Hoist the marking of excluded tracks out from GrowSelectedTracksUnlimited to a separate method (idempotent change).
1425599 part 12 - [css-grid] Merge CopyPlanToBase/Limits into a templated method instead (idempotent change).
1425599 part 13 - [css-grid] Merge Grow[Base|Limits]ForSpanningItems into a templated method instead (idempotent change).
1425599 part 14 - [css-grid] Use iterators instead of an array + start/end index for the item data (idempotent change).
1425599 part 16 - [css-grid] Make SizeContributionForPhase a template.
1425599 - [css-grid] Follow-up bustage fix for stupid compiler warnings.
1378481 - Assign 'roundingError' in the default branch too, to avoid a maybe-uninitialized compiler warning.
1423292 - [css-grid] Add a couple of ItemState bits to Dump(), and make an ItemState assertion stricter (DEBUG-only changes).
1373678 Part 1: Reduce grid line numbers by count of leading implicit lines, minimum 0.
1416350 - Part 1: Correctly account for removed 'auto-fit' tracks also when there are leading implicit tracks.
1416350 - Part 2: Correct logic for Grid API line numbering with leading implicit tracks.
1418727 part 1 - [css-grid] Introduce StateBitsForRange() that collects the union of the state bits for a range of tracks (idempotent change).
1418727 part 2 - [css-grid] Require that an item spans at least one track with an 'auto' min sizing function for Automatic Minimum Size to apply.
Tag #1052 (backout).
Backed out for creating issues like #1191 and other issue-less problems
with e.g. losing the caret from text boxes. Of note: this was also
backed out from m-c for similar reasons in Bug 1332433.
This fixes#1191.
This reverts commit 3424afccaebc71c4acd4fa9eadf519c408c5965b.
UXP has:
MOZ_RELEASE_ASSERT(sAliveDisplayItemDatas && sAliveDisplayItemDatas >Contains(this));
sAliveDisplayItemDatas->RemoveEntry(this);
and this gets hit during frame destruction.
Combine these checks.
* Simplify the dispatch-to-content region
Simplify the dispatch-to-content region in nsDisplayLayerEventRegions::AddFrame() and AddInactiveScrollPort() if it starts to get large.
* tabs to spaces
Some SVGs define a mask but an invalid mask frame. Check to make sure
we have a `maskFrame` that isn't null before trying to use it.
This resolves#1034
