Marko Kiiskila resolved MYNEWT-124.
-----------------------------------
Resolution: Fixed
Made console_printf() stream out when using baselibc.
This same change cannot be made for log_printf(), given the interface to
logging APIs. log_append() would need a way to append bytes one at a time to a
log entry.
> 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: Marko Kiiskila
> Fix For: v0_8_0_rel
>
>
> 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.
