| * Implemented in strace 5.6. |
Command-line option for syncing output to files on every line
Output staging for successful/failed syscalls (-z option)
- Implemented in strace 5.2.
Posssible extension: filtering by specific retval/errno (possible syntax: -e trace=...:{ret,retval,err,errno}{=,!=,<,<=,>,>=,&,!&}VAL)
There's a patch available (with hard-coded ANSI escape sequences, though)
Print memory related to addresses
Possible syntax: -e dump=syscalls:before=1024:after=512 (similar to dumpio())
Construct PID tree ("process lineage")
minimum/maximum beats per minute^W^W^Wtime spent in system call
- Implemented in strace 5.6.
Provide information about syscall names and numbers
- Mostly implemented as asinfo tool, needs UI rework
- Path tracing for -e read/write.
- Filtering for specific ioctl (or any other dispatch-like syscall command) numbers.
- ioctls are expecially tricky as one usually wants to trace one or several syscall classes and those are set in the middle of ioctl constant.
- msgid and any other id filters
- uid/gid?
- Combine -o| and -ff by allowing providing '{}' in the popen command line.
