I'd like to fix the seemingly incorrect variable expansion
implemented in testing.jam module's time action. However before
committing the change - I'd like to make sure this change will not break
something I'm not aware of at the moment.
Effect is that the time action will output something like:
user: xxxxx seconds
system: yyyyy seconds
into its target file instead of:
user: xxxxx" seconds"
system: yyyyy" seconds"
that it does now when run under the Windows cmd shell, i.e. using the
Windows echo command.
When using the unix echo command (e.g. under Cygwin) it should make
I grepped through Boost trunk and found no code that would be
affected by this. Is there something else like the automated regression
testing system or something related to the Boost library web site that
could get broken by this?
If there are no complaints - I'll go ahead and commit a change such
as presented in the following diff:
