[Bug 59893] New: ws2_32: libcurl uploads throttled to ~140 KB/s
by WineHQ Bugzilla Aug. 23, 2026

Aug. 23, 2026

http://bugs.winehq.org/show_bug.cgi?id=59893 Bug ID: 59893 Summary: ws2_32: libcurl uploads throttled to ~140 KB/s Product: Wine Version: 11.10 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: winsock Assignee: wine-bugs(a)list.winehq.org Reporter: wine-bugtrack(a)forryan.co.uk Distribution: --- Created attachment 81216 --> http://bugs.winehq.org/attachment.cgi?id=81216 Standalone C reproducer: select() writability vs send() acceptance Overview Single-stream uploads from a libcurl-based application run far slower under Wine than on Windows; roughly 140 KB/s regardless of available bandwidth. Found with Backblaze Personal Backup (its bztransmit uploader uses libcurl), where a large backup checkpoint could not finish within the client’s 600s upload timeout. The same operation completes in ~80s with the socket behaviour corrected. Steps to reproduce (self-contained; no application or account needed) A minimal reproducer is attached (sock_writable_test.c). It: 1. Creates a connected loopback TCP pair and sets the sender non-blocking. 2. Without ever reading from the receiver, repeatedly does a zero-timeout select() for writability on the sender, then a send() of a small buffer. 3. Counts iterations where select() reported the socket NOT writable yet the following send() still succeeded. Build: x86_64-w64-mingw32-gcc -O2 -o sockw.exe sock_writable_test.c -lws2_32 Run: wine sockw.exe Actual results On unmodified Wine (built from official source, ./configure && make, clean WINEPREFIX): the sender shows many iterations where select() reports not-writable while send() still succeeds (e.g. ~230 of ~660 sends), and the program prints FAIL. A real libcurl uploader that does a select() writability pre-check before waiting on FD_WRITE therefore stalls on its poll timeout between bursts. Expected results On Windows, the same program reports zero such iterations (PASS): select() reports a connected stream socket writable whenever send() would still accept data. Wine should match this. Analysis Wine appears to derive writability from the host poll(), and on Linux POLLOUT is only set once the send queue drains below ~2/3 of SO_SNDBUF, whereas Windows reports writable while the send buffer has any room. A fix and a ws2_32:sock conformance test are being submitted via a merge request. Environment * Wine: 11.10 Unmodified, built from official source (no Staging, no third-party wrapper, no DLL overrides, clean ~/.wine). * Distribution/architecture: Ubuntu 24.04, x86_64 * WINEARCH win64/64-bit prefix. See also curl issue #6146 (“Poor upload performance in Windows”) https://github.com/curl/curl/issues/6146 and https://github.com/curl/curl/pull/5634 - the Windows FD_WRITE/select-writability semantics involved. Bug 41379 (https://bugs.winehq.org/show_bug.cgi?id=41379) is the read-side (FD_READ) analogue; this is the write side. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59749] New: sapi: ISpVoice::SetPriority and GetStatus return E_NOTIMPL, breaking Overwatch 2 Audio Captions (and likely any SAPI app that polls status or checks SetPriority's HRESULT)
by WineHQ Bugzilla Aug. 23, 2026

Aug. 23, 2026

http://bugs.winehq.org/show_bug.cgi?id=59749 Bug ID: 59749 Summary: sapi: ISpVoice::SetPriority and GetStatus return E_NOTIMPL, breaking Overwatch 2 Audio Captions (and likely any SAPI app that polls status or checks SetPriority's HRESULT) Product: Wine Version: 11.8 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: sapi Assignee: wine-bugs(a)list.winehq.org Reporter: bohdan(a)tkachenko.dev Distribution: --- dlls/sapi/tts.c has three ISpVoice methods still stubbed out with FIXME(...stub...); return E_NOTIMPL; - spvoice_SetPriority (line 1231) - spvoice_GetPriority (line 1238) - spvoice_GetStatus (line 1212) SetPriority and GetStatus are both on the hot path for Overwatch 2's "Audio Captions" accessibility TTS feature (Steam AppID 2357570, runs under Proton - which ships unmodified upstream Wine SAPI). They cause two distinct failure modes: 1. During voice setup, OW2 calls ISpVoice::SetPriority(SPVPRI_NORMAL) and checks the HRESULT. E_NOTIMPL makes it abort TTS init entirely - PLAY SAMPLE produces silence and the in-game UI gives no error. 2. If SetPriority is forced to return S_OK (verified by binary-patching the stub), the engine successfully synthesizes the first sample. The game then calls ISpVoice::Speak(text, SPF_ASYNC, ...) and tight-polls ISpVoice::GetStatus waiting for SPVOICESTATUS.dwRunningState == SPRS_DONE. Stock GetStatus returns E_NOTIMPL and writes nothing into the status struct, so the game polls forever and subsequent PLAY SAMPLE clicks silently do nothing. Other SAPI apps that use Speak(SPF_DEFAULT) or Speak(SPF_ASYNC) + WaitUntilDone(INFINITE) never hit these methods and work fine on stock Wine, which is why this hasn't been reported before despite the stubs being old. OW2's accessibility code is unusually defensive. Steps to reproduce ================== 1. Install Wine 11.8+ (or any current Proton - same upstream code: ValveSoftware/wine branch proton_11.0 dlls/sapi/tts.c is byte-identical to wine-mirror/wine master, MD5 verified). 2. Install Overwatch 2 (free-to-play, Steam AppID 2357570) - or any SAPI app that checks SetPriority's HRESULT. 3. In game settings -> Accessibility, enable Audio Captions and select a Proton voice (e.g. "Proton Voice - English (United States) - LIBRITTS-R 14"). 4. Click PLAY SAMPLE. Actual: silence; in-game UI gives no error. With WINEDEBUG=+sapi: spvoice_SetVoice -> picks ProtonTTS_libritts-r_3 spvoice_SetOutput(NULL) -> default audio out spvoice_SetRate(3) -> S_OK spvoice_SetVolume(100) -> S_OK spvoice_SetPriority(0) -> STUB -> E_NOTIMPL [BUG #1] spvoice_Release -> game gives up here After binary-patching SetPriority to return S_OK: spvoice_Speak(text, SPF_ASYNC=1) -> audio plays once loop: spvoice_GetStatus(&status, NULL) -> STUB -> E_NOTIMPL, status untouched ... [BUG #2 - tight poll forever] Expected: PLAY SAMPLE plays the voice sample, and the button works again on every subsequent click. Workaround: binary-patch the two E_NOTIMPLs, or use a locally-built Wine with the patches below. Fix === A patch is being prepared for wine-devel implementing all three methods plus tests. Sketch: - SetPriority/GetPriority: store value on struct speech_voice, validate against SPVPRI_NORMAL/ALERT/OVER. - GetStatus: populate SPVOICESTATUS from cur_stream_num (last queued), a new last_stream_num/last_hr updated in speak_proc, and async_wait_queue_empty(&queue, 0) for dwRunningState. Patch verified against Wine's existing dlls/sapi/tests/ suite (new tests added) and end-to-end in OW2: both PLAY SAMPLE clicks play correctly with no wedge. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
