FrostWire for Mac

New

• FrostWire 7.1.2 is a security and responsiveness update to 7.1.1. On Windows, macOS and Linux it ships the Java runtime that fixes this week's severe Oracle Java security advisory. On Windows it also makes text sharp again on high-resolution displays and stops a class of UI freezes caused by the graphics driver. On every platform it removes dozens of places where the window could freeze for seconds while FrostWire waited on the disk, the network, the clipboard or the BitTorrent engine.

Security:

• The bundled Java runtime is updated to OpenJDK 27.0.1.0.3 on Windows, macOS and Linux. It replaces OpenJDK 27 (build 27+35) and fixes the vulnerabilities in this week's severe Oracle Java security advisory. FrostWire runs on the runtime inside its own installer, not on a Java you may have installed separately, so updating FrostWire is how you get the fix. The startup log now shows the full runtime build (27.0.1.0.3+1-2), so you can check which one you are running.

A more responsive FrostWire:

Build 333 started sending us the stack of every UI freeze longer than a few seconds. Those reports pointed at work that was being done on the UI thread, and 7.1.2 moves it to the background:

• Transfers: adding, removing, selecting, hovering, right-clicking, dragging, playing and restoring transfers no longer wait on the BitTorrent engine or the disk. The Seeding column, tooltips and file icons are prepared in the background, and status refreshes share a small thread pool instead of starting a thread per transfer every second.
• Transfers and search results no longer get slower the longer FrostWire runs. Table cells were adding a new mouse listener every time they were drawn, a leak that eventually froze the UI.
• Search: pressing Enter, typing (suggestions no longer render as HTML) and switching or closing search tabs no longer stall on slow machines.
• Library: scrolling no longer checks the disk for every row on every repaint, which froze on slow and network drives, and Options > Library folders no longer lists every subfolder just to draw its expand arrows.
• Windows: file icons in Transfers and in a torrent's file selection are fetched from Windows in the background, and switching back to FrostWire no longer waits for another app that is holding the clipboard.
• macOS: scrolling the Transfers and search tables no longer asks macOS for the mouse position for every cell drawn.
• Startup and idle: Java's text shaper, fallback fonts, drag-and-drop cursors and logging are warmed up in the background at launch, images are decoded in memory instead of through temporary files, and the status bar no longer rebuilds itself every few seconds or on every resize event.

Also new and fixed:

• Search results you already started downloading are marked with a download arrow, in later searches too. FrostWire keeps no list of your downloads for this, only a fixed-size Bloom filter of hashes that can recognize a result but cannot be read back (#950).
• Transfer Detail > Pieces shows what each piece is. Hover a cube to highlight it in orange and see a card with the piece's number, state (downloaded, downloading with block progress, missing or skipped), size, byte range, how many peers have it, priority, SHA-1 hash and the files it belongs to. The cubes are also drawn crisp at display scaling above 100%, re-wrap to the panel's width when you resize the window, and no longer leave stray line fragments or cut off the second to last row.
• The Peers tab in Transfer Detail updates again: speeds, totals and sorting refresh every second, disconnected peers disappear, and the Uploaded column shows a size (#1307).
• Fixed crashes when sorting changed during a background re-sort, when the Torrent Data library cache was cleared mid-scan, and when the shared background pool was busy (it now queues work instead of rejecting it).
• macOS: clicking FrostWire's Dock icon brings back its hidden window again; the listener for it failed to register at startup.
• FrostWire exits with a message instead of reporting a crash when started without a graphical session.
• Distributed Search writes its list of known IceBridge servers at most every 5 minutes, and atomically, so a crash can no longer leave it truncated.
• Freeze reports are sent once, with their stack, and are tagged (render-queue:, jdk-shellfolder:, stack-missed:, shutdown:) so that freezes inside Java or the graphics driver group apart from freezes in FrostWire's own code.
