Hi Keith,
As we discussed offline, your implementation of Popen will delay
printing any stdout
and stderr to the log files until the command is completed. This is
not desirable for
application that wants to see any output/error from long running command.
Users of those application might think the command is hung if they
don't see
the expected output from the commands in the log files.
It would be best to display any output/error from commands as soon as
it is "sensible".
Thanks for pointing out that use case! I've spun up a modified webrev.
The logic for the logging case is now much different - the general flow
copied from the existing exec_cmds_output_to_log function.
I see that you removed the reference to install_extra in
pkg/transforms/synthetics.
Are you also going to also remove the reference to repo.extra in
pkg/README.pkg so all
references are gone, even though it is harmless.
Per the Note at the top of README.pkg, that file was only ever a
reference and was never modified from its original source, the ON gate.
It has many references to things that don't apply to slim_source. As
such, I don't feel that maintenance of that file is worthwhile at this time.
Thanks,
Keith

Hi all,
I'd like a code review for my fixes for:
15957 <http://defect.opensolaris.org/bz/show_bug.cgi?id=15957> Implement
solaris_install.Popen
7014402
<http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=7014402> SUNW*
packages showing up in install-redistributable
webrev:
http://cr.opensolaris.org/~kemitche/webrev.15957/
Notes:
* solaris_install.Popen is a drop-in replacement for subprocess.Popen
- as verification, the test code actually runs the full
subprocess.Popen test suite against solaris_install.Popen.
* "exec_cmd" and its family have not yet been removed. I will file
bugs against the various installers to replace usage of such
functions with solaris_install.Popen invocations; this allows for new
consumers to use solaris_install.Popen now, rather than waiting an
indefinite amount of time for me (or someone) to pull out those
functions and widely re-test a large portion of the slim_source codebase.
* I initially considered doing a global find/replace of
subprocess.Popen with solaris_install.Popen. However, since
solaris_install.Popen is in the solaris_install module, in many cases
that results in a new Python import of a module not in the Python
standard library. This has potential implications on packaging
dependencies; as such, there are risk and time factors involved in
such a find/replace (in the form of at least sanity checking most
installers). As there will be bugs to remove "exec_cmd" functions
anyway, it seems appropriate to have those bugs also replace
subprocess.Popen with solaris_install.Popen. (The current approach
also is probably easier for the various projects to merge with)
Thanks,
Keith
