------------------------------------------
Summary: Log buffer issues
Key: MYNEWT-124
URL: https://issues.apache.org/jira/browse/MYNEWT-124
Project: Mynewt
Issue Type: Bug
Components: Misc
Reporter: Christopher Collins
Assignee: Sterling Hughes
Fix For: v0_8_0_beta2
When a message is written to a log, some buffers are allocated on the stack in
various places in the code. This results in two issues:
# Undue stack-size requirements placed on any task which uses sys/log.
# Hard limit placed on the maximum length of a log line.
There are two functions which exhibit this behavior:
* log_printf (LOG_PRINTF_MAX_ENTRY_LEN = 128)
* console_vprintf (CONS_OUTPUT_MAX_LINE = 128)
I do not have a proposed fix. I believe Marko suggested streaming bytes to the
destination, rather than writing to an intermediate buffer.
