Daniel P. Berrangé 012842c075 log: make '-msg timestamp=on' apply to all qemu_log usage Currently the tracing 'log' back emits special code to add timestamps to trace points sent via qemu_log(). This current impl is a bad design for a number of reasons. * It changes the QEMU headers, such that 'error-report.h' content is visible to all files using tracing, but only when the 'log' backend is enabled. This has led to build failure bugs as devs rarely test without the (default) 'log' backend enabled, and CI can't cover every scenario for every trace backend. * It bloats the trace points definitions which are inlined into every probe location due to repeated inlining of timestamp formatting code, adding MBs of overhead to QEMU. * The tracing subsystem should not be treated any differently from other users of qemu_log. They all would benefit from having timestamps present. * The timestamp emitted with the tracepoints is in a needlessly different format to that used by error_report() in response to '-msg timestamp=on'. This fixes all these issues simply by moving timestamp formatting into qemu_log, using the same approach as for error_report. The code before: static inline void _nocheck__trace_qcrypto_tls_creds_get_path(void * creds, const char * filename, const char * path) { if (trace_event_get_state(TRACE_QCRYPTO_TLS_CREDS_GET_PATH) && qemu_loglevel_mask(LOG_TRACE)) { if (message_with_timestamp) { struct timeval _now; gettimeofday(&_now, NULL); qemu_log("%d@%zu.%06zu:qcrypto_tls_creds_get_path " "TLS creds path creds=%p filename=%s path=%s" "\n", qemu_get_thread_id(), (size_t)_now.tv_sec, (size_t)_now.tv_usec , creds, filename, path); } else { qemu_log("qcrypto_tls_creds_get_path " "TLS creds path creds=%p filename=%s path=%s" "\n", creds, filename, path); } } } and after: static inline void _nocheck__trace_qcrypto_tls_creds_get_path(void * creds, const char * filename, const char * path) { if (trace_event_get_state(TRACE_QCRYPTO_TLS_CREDS_GET_PATH) && qemu_loglevel_mask(LOG_TRACE)) { qemu_log("qcrypto_tls_creds_get_path " "TLS creds path creds=%p filename=%s path=%s" "\n", creds, filename, path); } } The log and error messages before: $ qemu-system-x86_64 -trace qcrypto* -object tls-creds-x509,id=tls0,dir=$HOME/tls -msg timestamp=on 2986097@1753122905.917608:qcrypto_tls_creds_x509_load TLS creds x509 load creds=0x55d925bd9490 dir=/var/home/berrange/tls 2986097@1753122905.917621:qcrypto_tls_creds_get_path TLS creds path creds=0x55d925bd9490 filename=ca-cert.pem path=<none> 2025-07-21T18:35:05.917626Z qemu-system-x86_64: Unable to access credentials /var/home/berrange/tls/ca-cert.pem: No such file or directory and after: $ qemu-system-x86_64 -trace qcrypto* -object tls-creds-x509,id=tls0,dir=$HOME/tls -msg timestamp=on 2025-07-21T18:43:28.089797Z qcrypto_tls_creds_x509_load TLS creds x509 load creds=0x55bf5bf12380 dir=/var/home/berrange/tls 2025-07-21T18:43:28.089815Z qcrypto_tls_creds_get_path TLS creds path creds=0x55bf5bf12380 filename=ca-cert.pem path=<none> 2025-07-21T18:43:28.089819Z qemu-system-x86_64: Unable to access credentials /var/home/berrange/tls/ca-cert.pem: No such file or directory The binary size before: $ ls -alh qemu-system-x86_64 -rwxr-xr-x. 1 berrange berrange 87M Jul 21 19:39 qemu-system-x86_64 $ strip qemu-system-x86_64 $ ls -alh qemu-system-x86_64 -rwxr-xr-x. 1 berrange berrange 30M Jul 21 19:39 qemu-system-x86_64 and after: $ ls -alh qemu-system-x86_64 -rwxr-xr-x. 1 berrange berrange 85M Jul 21 19:41 qemu-system-x86_64 $ strip qemu-system-x86_64 $ ls -alh qemu-system-x86_64 -rwxr-xr-x. 1 berrange berrange 29M Jul 21 19:41 qemu-system-x86_64 Signed-off-by: Daniel P.
