- Mark a method as `static`
- use `Math.sqrt` instead of `Math.pow(…, 0.5)`
- Use `Math.sign` instead of a condition on the sign
- Inline some used-once variables
- Reduce the scope of some variables
According to https://caniuse.com/?search=passive,
all browsers released after 2016 do support passive event listeners,
so no need to check for its presence.
- Use `….classList.toggle` instead of `….classList.add`/`….classList.remove` in a condition
- Replace a `function()` with a `() =>`
- Use `Math.min` instead of a handwritten condition
Miniflux can be build with `go build -tags=sqlite` to test this. Note that
while it builds, it will fail at runtime, as some of the SQL used in miniflux is
postgresql-specific.
The implementation is equivalent to
`cases.Title(language.English).String(strings.ToLower(…))`,
and this is the only place in miniflux where
"golang.org/x/text/cases" and "golang.org/x/text/language"
are (directly) used.
This reduces the binary size from 27015590 to
26686112 on my machine.
Kudos to https://gsa.zxilly.dev for making it straightforward to catch things
like this.
- Use chained strings.Contains instead of a regex for
blacklistCandidatesRegexp, as this is a bit faster
- Simplify a Find.Each.Remove to Find.Remove
- Don't concatenate id and class for removeUnlikelyCandidates, as it makes no
sense to match on overlaps. It might also marginally improve performances, as
regex now have to run on two strings separately, instead of both.
- Add a small benchmark
Some websites are using images of O(10kB) when not )O(100kB) for their
favicons. As miniflux only displays them with a 16x16 resolution, let's do our
best to resize them before storing them in the database. This should make
miniflux consume less bandwidth when serving pages, for the joy of mobile users
on a small data plan.
Of course, images that already are 16x16 aren't resized.
No need for brittle regex when matching plain strings or domain names.
This should save some negligible amount of heap memory as well as
tremendously speeding up the matching.
- Replace a completely overkill regex
- Use `.Remove()` instead of a hand-rolled loop
- Use a strings.Builder instead of a bytes.NewBufferString
- Replace a call to Fprintf with string concatenation, as the latter are much
faster
- Remove a superfluous cast
- Delay some computations
- Add some tests
As mentioned in goquery's documentation (https://pkg.go.dev/github.com/PuerkitoBio/goquery#Single):
> By default, Selection.Find and other functions that accept a selector string
to select nodes will use all matches corresponding to that selector. By using
the Matcher returned by Single, at most the first match will be selected.
>
> The one using Single is optimized to be potentially much faster on large documents.
In internal/reader/handler/handler.go:RefreshFeed, there is a call to
store.UserByID pretty early, which is only used for
originalFeed.WithTranslatedErrorMessage(localizedError.Translate(user.Language)
Its only other usage is in processor.ProcessFeedEntries(store, originalFeed,
user, forceRefresh), which is pretty late in RefreshFeed, and only called if
there are new items in the feed. It makes sense to only fetch the user's
language if the error localization function is used.
Calls to `store.UserByID` take around 10% of the CPU time of RefreshFeed in my
profiling.
This commit also makes `processor.ProcessFeedEntries` take a `userID` instead
of a `user`, to make the code a bit more concise.
This should close#2984
