I continued profiling the matchbrackets addon for T270237 and run into
performance issues that turned out to be unrelated to the addon. The
flame graph highlighted a "match" function. Note this is not the
String.match() from JavaScript, but something in the CodeMirror lib:
StringStream.prototype.match = function (pattern) {
var match = this.string.match(pattern);
if (match && match.index > 0) {
return null;
}
return match;
}
(Note: I simplified this code so we can focus on the bug.)
When the pattern is a regular expression, it's executed via
JavaScript's String.match(). The function then checks if there was a
match and if it's at the start of the string. If not, it's not a
match and doesn't return one.
In other words: Even if there is a match somewhere in the string, the
function acts as if there was no match.
When we change all patterns to be anchored via ^, they don't scan the
entire string any more but return much ealier when there is no match
at the start of the string. We are effectively replacing nested loops
(hidden in the patterns) with single calls.
This bug exists since 2014.
The disabled line in the matchbrackets addon is just dead code. I
don't remove it to document the fact that we disabled it.

I had to make some CSS selectors more specific, because the
library changed
.CodeMirror pre
to
.CodeMirror pre.CodeMirror-line,
.CodeMirror pre.CodeMirror-line-like
This is only relevant for entire lines (implemented as <pre>
elements). Most of the custom CSS is for characters, not lines.
In my tests in the Wikitext editor as well as VisualEditor I
could not spot any difference between the old and new version.

The rgba() syntax is supported for a very, very long time now:
https://caniuse.com/#feat=mdn-css_types_color_alpha
Notes:
I realized the numbers in these file names are actually their
transparency in percent (more precisely their opaqueness).
4 is 4% which translates to 0.04 in the rgba() syntax.
I used Gimp to pick the opaque color values from the images.
Gimp makes this easy. No guesswork or calculations needed.
For multiple, stacked images I calculated the colors by
averaging their RGB values (considering how opaque each color
is). Note this is actually *more* precise than the stacked
images before. Stacking alpha colors is flawed. For example:
Let's say we have an rgba(255, 255, 255, 1) background.
Layering a half transparent rgba(255, 0, 0, 0.5) on top means
half the background shines through. This averages to
rgba( 255, 127, 127, 1). Now we stack rgba(0, 0, 0, 0.5) on
top. Again, half the background shines through, resulting in
rgba(127, 63, 63, 1).
When we apply the two colors the other way around, the result
is rgba(191, 63, 63, 1), a much brighter red.
This flaw doesn't happen when precalculating the averages, as
done in this patch.

CodeMirror inserts
style="padding-right: 0.1px;"
only on Webkit.
The test case now strips this pattern from the rendered HTML before
comparing with the expected test case output.

This patch makes initialization easier and cheaper.
Since only the PhpTags extension uses the CodeMirrorGetAdditionalResources
hook it was removed. Instead, the CodeMirrorPluginModules and
CodeMirrorTagModes properties are used in extension.json file.
This patch adds ext.CodeMirror.lib.mode.php module for the PhpTags
extension (with dependences). In CodeMirror there are a lot of modes
they will be registered on request (if they will be requered for
extensions).
Examples of integration:
* Cite: I1bf156fa813af4d5f891619f692047bbdb8a1a86
* PhpTags: Ie339f0475e63885e603defaee2cdcccd6a95fafc

Zopfli is the most efficient DEFLATE compression algorithm, trading run-time
performance for file sizes that are typically 3-8% smaller than those produced
by zlib with the maximum compression setting. Its output is Deflate-compatible,
so no specialized decoder is needed.
This change was created by running zopflipng against all the PNG files in this
repository. The exact invocation was:
git ls-files --exclude-per-directory=.gitignore -- '*.png' \|
parallel zopflipng -m -y --iterations=500 --filters=01234mepb {} {} \;
Files which zopflipng was not able to compress more efficiently were left unmodified.
