| Description: | ||||
When writing a file that exceeds the size allowed by ulimit -f, Tcl panics (File size limit exceeded). This can easily be turned into a more reasonable I/O error (file too large). See the attached patch. | ||||

Still happens in 8.6 and 9.x: the process is killed by SIGXFSZ. Proposed fix in branch unix-ignore-sigxfsz:
the attached patch, plus restoring the default action of SIGXFSZ in child
processes, as for SIGPIPE, since ignored signals are inherited across

Fixed in [9a3e24fe8a62c7db|trunk], backported to core-9-0-branch and core-8-6-branch. But without the testcase: It may work on Linux, but won't work on all possible platforms (it doesn't work on Cygwin). Many thanks! | ||||
