* sze/to_erl/OTP-11206: Fix changing terminal parameters in to_erl
2013-07-22Fix changing terminal parameters in to_erlStefan Zegenhagen
One of our devices does not like 'to_erl' to be run over a serial port. When to_erl is started, we see "Attaching to /tm<0xFF>" being printed and the device then refuses to accept any input. Occasionally, we have seen a linux kernel error message "serial8250: too much work for irq16" simultaneously. After some debugging we found out that cause is a call to tcsetattr() by to_erl, immediately preceeded by some printf(). The UART in our device doesn't like hardware parameters to be changed while output is concurrently active. In fact, the GNU libc manual also mentions that it might be dangerous to change UART hardware parameters when a transmission is ongoing. The patch attached to this e-mail changes the behaviour of to_erl to use TCSADRAIN instead of TCSANOW when changing terminal parameters. This makes the serial driver wait for the output queues to be empty before applying the terminal parameter change.

Like in epmd and erlexec. Otherwise "run_erl" fails on some platforms when called with the "-daemon" option, printing this error: "Cannot dup"

2012-08-02Use thread progress instead of scheduling misc aux work were possibleRickard Green
Functionality for scheduling operations at thread progress later has been introduced. Deallocation of ETS table structures were previously done by scheduling misc aux work. Deallocation of process structures (not released yet) was also implemented this way. Instead of using the misc aux work functionality these implementation now use the newly introduced functionality for scheduling operations at thread progress later. By using this new functionaliy we reduce the amount of memory allocation/deallocation operations needed.

2011-05-11cerl: Fix several incompatibilities with 'erl'Björn Gustavsson
Invoking 'cerl' like 'cerl -smp' would only start the smp emulator if default was to start the non-smp emulator, otherwise 'erlexec' would try to start 'beam.smp.smp'. Furthermore 'cerl -smp disable' would be handled in the same way as 'cerl -smp'.
2011-05-11cerl: Remove ancient obsolete optionsBjörn Gustavsson
The -frag and -smp_frag options was used to start an (at the time) experimental build of the emulator. The -shared and -hybrid option was used to start experimental versions of the emulator with alternate heap architectures.
2011-05-02Teach run_erl RUN_ERL_DISABLE_FLOWCNTRL for disabling flow controlJonas Faklkevik
Flow control can cause unwanted behaviour of the beam process, if accidentally hit Ctrl-S (instead of Ctrl-D to detach) the entire beam may be blocked. Fix this problem by making it possible to turn off flow control by setting the environment variable RUN_ERL_DISABLE_FLOWCNTRL.
