* stray stdout/stderr/pseudo console garbage output @ 2020-02-08 17:19 Thomas Wolff 2020-02-08 23:48 ` Takashi Yano 0 siblings, 1 reply; 3+ messages in thread From: Thomas Wolff @ 2020-02-08 17:19 UTC (permalink / raw) To: cygwin When I run mintty in the background from a nested shell, like    mintty & within a shell script, or    (mintty &) from an interactive shell, and it produces the following error output, some stray string is appended to its output, like: Ignoring unknown option 'ShowTabBar'. Font not found, using system substitute: Luxi Monotch??????               ffer: pty0: pcon or: Ignoring unknown option 'ShowTabBar'. Font not found, using system substitute: Luxi Mono     2 [main] mintty 1551 fhandler_pty_slave::push_to_pcon_screenbuffer: pty0: pcon_attach_to mismatch?????? The first message ("Ignoring ...") is written with fprintf(stderr, ...). The second message ("Font not found") is written with fputs(..., stderr). Without specific mintty configuration, reproducible with the command (parentheses needed): (mintty --fn "dummyfont" -o dummyopt=none&) Observable with 3.1.0, 3.1.2 or snapshot 2020-01-31. Sorry, I could not reduce the test case to a simpler setup.

This output is generated by debug code in pty when some buggy condition is detected. It seems that pty code still has bug... -- Takashi Yano <takashi.yano@nifty.ne.jp> -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple ^ permalink raw reply [flat|nested] 3+ messages in thread

It seems that pty code still has bug... I have found the culprit. I will submit a patch for this issue shortly. -- Takashi Yano <takashi.yano@nifty.ne.jp> -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple ^ permalink raw reply [flat|nested] 3+ messages in thread
