fix(sync): Destroy condition variables - #2004
Merged

Conversation
Add cross-platform condition-variable cleanup and invoke it when thread pools, background workers, flush tasks, and app-hang monitors are released. Condition variables may own implementation-specific resources, and POSIX requires destroying an initialized condition variable before reinitializing it. Close the semaphore and event handles owned by the pre-Vista emulation. Update synchronization tests to clean up their condition variables. Keep the task-queue notification under its predicate mutex so teardown cannot race with an in-flight signal.

Brings in fb337fb (getsentry#2004). The only conflict was CHANGELOG.md, where both getsentry#2004 and this branch appended an entry to the same Unreleased "Fixes" list; both entries are kept, with getsentry#2004 first since it is already on master.

sentry-native 0.16.4 Created-by: HarmonybrewBot Commit-by: HarmonybrewBot Merged-by: HarmonybrewBot Description: Created by `brew bump` --- Created with `brew bump-formula-pr`. - [ ] `resource` blocks have been checked for updates. <details> <summary>release notes</summary> <pre>**Features**: - Windows: report WINE and Proton metadata in a separate runtime context. ([#1995](getsentry/sentry-native#1995)) - Add a public custom HTTP transport client interface (`sentry_http_transport_new`) so applications can plug in their own HTTP client (e.g. platform-native ones) while sentry-native continues to own request queueing, retry/backoff, offline caching, rate-limiting, and client reports. The built-in curl and WinHTTP transports are now implemented against this same interface. ([#1987](getsentry/sentry-native#1987)) - Native/Windows: capture WER report ID and expose as `contexts.wer.report_id` in crash events when the WER integration is enabled. ([#1970](getsentry/sentry-native#1970)) - Add `sentry_set_tags` and `sentry_scope_set_tags` for updating multiple tags with a single scope flush, improving bulk-update performance. ([#1993](getsentry/sentry-native#1993)) - Add `on_crashed_last_run` callback for inspecting crash envelopes from previous runs. ([#1985](getsentry/sentry-native#1985)) - Add `sentry_get_last_event_id` and `sentry_scope_get_last_event_id` for retrieving the last event ID captured with the global or given scope, respectively. ([#1992](getsentry/sentry-native#1992)) - Native/Unix: The native crash daemon now loads `libcurl` dynamically at runtime by default when `SENTRY_LINK_CURL=AUTO`, avoiding `libcurl` linker work during process startup and significantly speeding up startup time. Explicitly set `SENTRY_LINK_CURL=ON` to link it directly. ([#1955](getsentry/sentry-native#1955)) - Add missing public scope mutators: `set_release`, `set_environment`, `set_transaction`, `remove_tag`, `remove_extra`, `remove_context`, and `remove_attachment`. ([#2011](getsentry/sentry-native#2011)) **Deprecations**: - Deprecate `sentry_options_get/set_enable_logs` and `sentry_options_get/set_enable_metrics`. ([#2000](getsentry/sentry-native#2000)) **Fixes**: - Native: store daemon logs, minidumps, crash envelopes, and scratch files in `.run` directories so they are cleaned up with the run instead of accumulating in the database root. Minidumps can still be retained with `cache_keep`, which stores `.dmp` sidecars alongside cached envelopes. ([#1976](getsentry/sentry-native#1976)) - Linux/ARM32: prevent recursive crashes when libunwind receives an unmapped initial instruction pointer during crash handling. ([#1977](getsentry/sentry-native#1977)) - Improve log and metric delivery when telemetry is captured faster than envelopes can be serialized by offloading serialization to an internal thread pool. ([#1946](getsentry/sentry-native#1946)) - Wine: fix OS version detection and cross-compiling Windows builds from Linux. ([#2001](getsentry/sentry-native#2001)) - Destroy condition variables as approriate when no longer needed. ([#2004](getsentry/sentry-native#2004)) - Crashpad/Windows: preserve module CodeView UUIDs for minimal PDB70 records with empty PDB filenames. ([#2003](getsentry/sentry-native#2003)) - Native/Windows: improve crash-processing performance for applications with many threads. ([#2018](getsentry/sentry-native#2018)) - Prevent a race between SDK reinitialization and cleanup of the previous curl client when libcurl is linked directly. ([#2015](https://github.com/getsentry/sentry-native/pull/2015))</pre> <p>View the full release notes at <a href="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/getsentry/sentry-native/releases/tag/0.16.4">https://github.com/getsentry/sentry-native/releases/tag/0.16.4</a>.</p> </details> <hr> See merge request: Harmonybrew/homebrew-core!17725
