[ast-developers] AT&T Software Technology ast alpha software download update

[Glenn Fowler]

the AT&T Software Technology ast alpha 2013-08-07 source release
has been posted to the download site
http://www.research.att.com/sw/download/alpha/
the package names and md5 checksums are
INIT 47f2073fae4b73fe5210cc4e287556ca
ast-open e6927faa687a2af8ee94431b793c08ac
ast-ksh 43b7379fdf573811c66f41ce231cbac0
the md5 sums should match the ones listed on the download page

still tracking down build problems and regressions on some systems / compilers
*in general no new features until then*
except for ksh93v- and features required to fix problems and regressions

our macos now has clang as the default cc so playing nice with it is at the top of the list

why so many problems and regressions?
adding patches is easy
getting them right is hard
especially the ones that require emulation

fus3d is a work in progress replacement for 3d -- still missing some features

changes since 2013-07-27

:::::::: gzip ::::::::

13-07-30 gzip.c: 6 now default compression level (same as gzip(1)) for 5x time savings for negligible size in some cases

:::::::: fus3d ::::::::

2013-07-29 snarf from amazing dr.ek, ast-ize, and its alive

:::::::: ksh93 ::::::::

13-08-05 --- Release ksh93v- ---
13-08-05 Fix a bug in which read -C could reference uninitialized memory.
13-07-31 Fixed a bug with index arrays of short integer types in arrays
inside types that could lead to a core dump.
13-07-30 Fixed a bug with short integer arithemtic that could lead to a
core dump.
13-07-30 +An experimental change to each enumeration variable have subvariables
for each enumeration constant. ${enum.name} will expand to the
numerical value of the enumeration name associatied with enum.
13-07-30 +An experimental change to allow ${foo.__} to expand to the parent
node for foo, or foo if foo doesn't have a parent. There are no
regression tests for .__ yet.

:::::::: setid ::::::::

13-07-31 first release

:::::::: tw ::::::::

13-08-02 find: add { -show -delete } for gnu/sol compatibility

13-07-30 codexlist.c: work around installations with obsolete vcodex plugin

:::::::: libvcodex ::::::::

13-08-07 vcodex.h,vcsfxsort.c: ssize_t (64 bit) => Vcinx_t (32 bit) -- noticable affect on memory footprint

ksh -c 'namespace cn.edu.pku.lib.wlin1 { true ; }'
/home/wlin/bin/ksh: cn.edu.pku.lib.wlin1: is not an identifier

Is there going to be a separate patch for this or was this feature rejected?

changes since 2013-07-27 does not mention rune
tr was fixed in a previous alpha -- modulo the proposed new feature rune were there any tr problems?

alpha/beta cycle. Sometimes the lack of development schedule
performance causes me to rip out my hairs, quite literally. Just
saying that as the diff we use at GE Healthcare to patch ksh93 is
nearly as large as the ast-ksh sources. And that's not a good sign.

sorry about the size of the diffs
if there were only one target that would be true
but with multiple targets even a change like adding fgetcwd() can burn a full day
since its my days being burned I lean towards build stability first
then new features

Why does it take a *full day* to do that? I'm sometimes amazed where
the time is spend, but please surprise me: Why does it take a day?
Typically for big projects like kernel.org (Linux kernel, which is way
way larger than AST) you stage a patch and kick off the automated
build and test systems to collect feedback from all platforms. That
hardly takes 2-3 hours, but not a day.

Typically for big projects like kernel.org (Linux kernel, which is way
way larger than AST) you stage a patch and kick off the automated
build and test systems to collect feedback from all platforms. That
hardly takes 2-3 hours, but not a day.

the build on the master source host is easy
then one command syncs the source on the build farm and builds
24 hosts => 37 different arch's -- diff cc / options / 32 vs 64 bit / etc
most hosts finish in 1 to 15 minutes depending on the change
touching some headers => more recompilation
then one command to run the regression tests
then one command to view the regressions

so there's your hardly 2 hours

now add in the time to deal with build failures:
* header contention between ast / cc / native
* symbol contention between ast / cc / native static and dynamic libs
* new compiler error / warnings
suppose just one host fails
remediation involves:
* debug changes on the failed host
* move changes back to master host
* restart from the top

add in
* "ast is not gsf/dgk's only job"
* only change a few things at a time before hitting the farm to keep sanity
* code review patches to see if parts are already done in ast
and days start vaporizing

I deferred all the namespace changes to a later release.

I addition to types in namespaces, there is also the question of
nested namespaces. When I added namespaces I was envisioning
a nested namespace model and namepace names would be identifiers.

The alternative, which Roland sent a patch for allows does not allow
for nesting, but allows namespaces to be named by a compound variable.

Thus, resarch.att.com could be the name of a namespace, but that does
not mean that research.att is a namespace and that of I am in
research.att.com, that if there is a namespace named research.att,
that it will be searched. I just means that variables not found
in research.att.com will be searched for in the global namespace.

The issue with namespace types that needs to be worked out is
how the namespace for type names will be handled. Currently gobal types
are kept in .sh.type.typename. I suspect that types defined in
namespace foo, should be kept in .foo.sh.type.typename but I haven't
modified the code for this. I do have it on my list, bug I have a few
bug fixes to go before I start on it.

What often happens is that a change breaks some regression test in one
or more architectures and it takes time to understand why which seems
to be an unrelated change causes this. This can take hours.
