[Bug 58198] New: Wine missing WH_JOURNALPLAYBACK, required by VB SendKeys
by WineHQ Bugzilla June 22, 2025

June 22, 2025

http://bugs.winehq.org/show_bug.cgi?id=58198 Bug ID: 58198 Summary: Wine missing WH_JOURNALPLAYBACK, required by VB SendKeys Product: Wine Version: 8.0 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: user16 Assignee: wine-bugs(a)winehq.org Reporter: jxvhulzowyrobfwwze(a)nbmbb.com Distribution: --- Wine doesn’t implement WH_JOURNALPLAYBACK, which is required by the Visual Basic SendKeys function. This makes the game “Mordor: The Depths of Dejenol” unplayable after entering the dungeon. I’ve confirmed with 32-bit Wine 8 and 16-bit VB3, but the logic seems unchanged in more recent Wine (and VB) versions. Microsoft eventually released a VB6 runtime that reimplemented SendKeys using SendInput instead of WH_JOURNALPLAYBACK, but that only fixes VB6 binaries. https://archives.miloush.net/michkap/archive/2007/09/10/4850360.html https://web.archive.org/web/20130615064311/http://blogs.msdn.com/b/michkap/… The story gets worse for programs that invoke DoEvents after SendKeys. Since DoEvents “first clears all pending keystrokes from the SendKeys function,” it enters an endless loop waiting for PeekMessage to return the expected WH_JOURNALPLAYBACK messages. CPU usage goes to 100%, and it’s easy to run out of stack space if DoEvents is invoked repeatedly. https://nolongerset.com/how-doevents-works/ Thankfully, running with WINEDEBUG=warn emits a clear message, “SetWindowsHookEx16 hook type 1 broken in Win16” pointing us to https://gitlab.winehq.org/wine/wine/-/blob/master/dlls/user.exe16/hook.c This game is particularly creative, using SendKeys as some sort of input filter. Many keyboard and mouse inputs are apparently translated to SendKeys calls. I don’t fully understand the logic, except that the game is unplayable without it. I can’t say whether it’s worth fixing this or not. At the very least, it’s helpful to know why this game doesn’t work, without having to keep trying each new Wine release.

[Bug 58401] New: system.fill_battery_state: support battery drivers that expose energy_* instead of charge_* attributes of power_supply_class
by WineHQ Bugzilla June 20, 2025

June 20, 2025

http://bugs.winehq.org/show_bug.cgi?id=58401 Bug ID: 58401 Summary: system.fill_battery_state: support battery drivers that expose energy_* instead of charge_* attributes of power_supply_class Product: Wine Version: 10.10 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: enhancement Priority: P2 Component: ntdll Assignee: wine-bugs(a)winehq.org Reporter: rtdiasmendes(a)gmail.com Distribution: --- File: system.c Method: fill_battery_state( SYSTEM_BATTERY_STATE *bs ) Current implementation: - Assumes battery driver exposes: "charge_now", "charge_full", "voltage_now" and "current_now". - Populates SYSTEM_BATTERY_STATE with those attributes after converting to expected units Issue: - Some battery drivers expose different ABI-compliant attributes - In systems with those drivers, Wine is incapable of emulating windows behaviour Enhacement proposal: - Add support for drivers that expose different attributes Further reading: - https://docs.kernel.org/power/power_supply_class.html - https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-devices-power - https://github.com/torvalds/linux/blob/master/include/linux/power_supply.h - https://github.com/torvalds/linux/blob/master/drivers/power/supply/power_su… Note: Attribute "scope", while implemented in the kernel, is undocumented in the power_supply_class docs. Will later check if the rest of the documentation is up to date and raise the appropriate issue upstream. Until then, do not assume it correctly reflects the kernel implementation. Out-of-scope commentary: While Wine's behavior of querying /sys/class/power_supply/ on every NtPowerInformation() call correctly emulates the Windows API semantics, it has unintended performance implications on Linux. This is due to the fact that retrieving battery information from sysfs involves real filesystem I/O, including frequent failed lookups on systems that expose energy_* instead of charge_* attributes. Therefore, applications may call NtPowerInformation() without prioritizing caching or proper fallback logic as they expect the operation to have a lower-cost then it does on Linux - causing significant and unnecessary performance degradation. This may merit its own enhacement proposal if it results in noticeable performance degradation. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 58397] New: Missing power_supply class attributes for NtPowerInformation blocks threads and causes fps stutter
by WineHQ Bugzilla June 20, 2025

June 20, 2025

http://bugs.winehq.org/show_bug.cgi?id=58397 Bug ID: 58397 Summary: Missing power_supply class attributes for NtPowerInformation blocks threads and causes fps stutter Product: Wine Version: unspecified Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: ntdll Assignee: wine-bugs(a)winehq.org Reporter: rtdiasmendes(a)gmail.com Distribution: Mint Created attachment 78805 --> http://bugs.winehq.org/attachment.cgi?id=78805 logs mentioned in the bug Description Affected Application: - Tainted Grail: Fall of Avalon Observed Symptoms: - Frametime spikes from ~5ms to ~100ms occurring at ~1Hz intervals. - GPU frame dispatch (via DXVK) is delayed due to thread blocking in Wine’s battery status polling logic. Performance Analysis (see attached logs): - strace shows constant, repeated attempts to read nonexistent files in /sys/class/power_supply/BAT1/ - perf stat reveals ~8,270 openat() syscalls in 10 second window (on game title screen). - perf record/report shows significant thread time consumed inside NtPowerInformation-related logic in ntdll. Root Cause: - In dlls/ntdll/unix/system.c, the function fill_battery_state() (Linux version) hardcodes the use of attributes: "charge_now" "charge_full" and "current_now". - These attributes are not universally present in /sys/class/power_supply/. On some systems, particularly those using energy-based reporting (µWh), the ABI-compliant alternatives are: "energy_now", "energy_full" and "power_now". - Since Wine looks only for the "charge_*" files and fails to return expected information, the game loops the query constantly which results in openat() being used in a tight polling loop - blocking threads and causing intermittent CPU stalls that propagate to the GPU rendering pipeline. Solution 1: - Verify what attributes are present in the power_supply class. - Implement logic with supplied attributes. Solution 2: - Attempt to read the already-implemented files. - Fallback to "energy_*" if those are not present. I gather solution 1 has a more consistent impact across different systems, while solution 2 is more lightweight on systems with "charge_*" and heavier on others. Further reading: - https://docs.kernel.org/power/power_supply_class.html - https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-devices-power - https://github.com/torvalds/linux/blob/master/include/linux/power_supply.h - https://github.com/torvalds/linux/blob/master/drivers/power/supply/power_su… Note: Attribute "scope", while implemented in the kernel, is undocumented in the power_supply_class docs. Will later check if the rest of the documentation is up to date and raise the appropriate issue upstream. Until then, do not assume it correctly reflects the kernel implementation. Disclaimer: This issue was identified and reproduced using Proton-GE, Proton (Steam Runtime), Soda and Flatpak's build. I am reporting it here for visibility and discussion since it appears to originate from WineHQ’s upstream implementation of NtPowerInformation. Out-of-scope commentary: While Wine's behavior of querying /sys/class/power_supply/ on every NtPowerInformation() call correctly emulates the Windows API semantics, it has unintended performance implications on Linux. This is due to the fact that retrieving battery information from sysfs involves real filesystem I/O, including frequent failed lookups on systems that expose energy_* instead of charge_* attributes. Therefore, applications may call NtPowerInformation() without prioritizing caching or proper fallback logic as they expect the operation to have a lower-cost then it does on Linux - causing significant and unnecessary performance degradation. Will raise this for an enchancement in the proper channels. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
