[Python-Dev] Python 0.9.1

[Skip Montanaro]

A note to webm...@python.org from an astute user named Hiromi in Japan* referred us to Guido's shell archives for the 0.9.1 release from 1991. As that wasn't listed in the historical releases README file:

https://legacy.python.org/download/releases/src/README

I pulled the shar files (and a patch), then made a few tweaks to get it to build:

% ./python
>>> print 'hello world!'
hello world!
>>> import sys
>>> dir(sys)
['argv', 'exit', 'modules', 'path', 'ps1', 'ps2', 'stderr', 'stdin', 'stdout']
>>> sys.modules
{'builtin': <module 'builtin'>; 'sys': <module 'sys'>; '__main__': <module '__main__'>}
>>> sys.exit(0)

I then pushed the result to a Github repo:

https://github.com/smontanaro/python-0.9.1

There is a new directory named "shar" with the original files, a small README file and a compile.patch file between the original code and the runnable code.

It was a pleasant diversion for a couple hours. I was tired of shovelling snow anyway... Thank you, Hiromi.

Awesome, Skip!

Was there a date somewhere? I can't recall if this would have been the first open source release (from just about 30 years ago, sometime in February 1991) or some time later in the same year?

Wow. Was white-space not significant in this release of Python? I see the lack of indentation in the first Python programs.

Indentation most certainly was significant from day 0. I suspect what happened is that these files got busted somehow by the extraction process used by Skip or Hiromi.

Yes, that's certainly possible. While it's nice that Google has archived this stuff, their faithfulness to the original formats leaves a bit to be desired (and gmane still doesn't work for me, eliminating that option). Guido's messages are displayed as HTML, and I saw no way to get at the raw Usenet messages. I just copied the shar data and saved the result. It seems clear that tabs copied as spaces. The Makefile indentation was hosed up. It should have dawned on me that the .py, .c and .h files would be messed up as well. I was only concerned with building the interpreter.

If someone knows how to get the original Usenet messages from what Google published, let me know.

Seems the original shar is there buried in a Javascript string toward
the end of the file. I think I've got a handle on it, though it will
take a Python script to massage back into correct format.

Very interesting discovery! In my efforts to uncover the original
plaintext usenet post, I stumbled across this 12-year-old diary/blog
post: http://www.dalkescientific.com/writings/diary/archive/2009/03/27/python_0_9_1p1.html

A little further digging led to
https://www.python.org/download/releases/early/ which references the
above post and is the first hit on Google for the search query
"alt.sources python 0.9.1" (without the quotes).

> As that wasn't listed in the historical releases README file

It would be good to add it to that.

Thanks, Paul. I had lost track of Andrew. Good to know he's still out
there. I wonder why his tar file was never sucked up into the
historical releases page.

Whew! My stupid little extraction script did a reasonable job. I see
plenty of differences, but a cursory examination shows they are only
in leading whitespace. Where I translated "\t" to TAB, it seems Andrew
used a suitable number of spaces. Python modules/scripts seem more
plausibly indented, and the couple I tried worked, so I'm a bit more
confident I have things right:

% PYTHONPATH=lib ./src/python
>>> import string
>>> print string.upper('hello world!')
HELLO WORLD!
>>>
% ./src/python lib/fact.py
99999
[3, 3, 41, 271]
4096
[2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2]

The tests don't pass though. 1 * 1 raises an integer overflow exception:

>>> 1 * 1
Unhandled exception: run-time error: integer overflow
Stack backtrace (innermost last):
File "<stdin>", line 1

I'll let someone figure that out. :-)

At any rate, the git repo has been updated.

I don't have those, but I do have a copy of Python 0.9.1 with unmangled
scripts.

$ ls -lh Python-0.9.1.tar.gz
-rwxr-xr-x 1 steve steve 379K Nov 5 2009 Python-0.9.1.tar.gz

I don't remember where I got it from, but it compiled on CentOS release
5.11, I'm not sure if it will compile on anything newer.

Skip, if you would like me to email it to you privately, let me know.
(Likewise for anyone else.)

The original ones are here:

Look at http://ftp.fi.netbsd.org/pub/misc/archive/alt.sources/index.gz

they extract flawlessly using unshar.

I guess you got it from here: https://www.python.org/download/releases/early/

Compared to the original, this one has a lot of whitespace changes.
Mostly tabs -> spaces.

You are probably looking at Andrew Dalke's experiment from 2009:

This is getting a bit more off-topic for python-dev than I'd like. I
will make a couple comments though, then hopefully be done with this
thread.

Thanks. Will check them out.

Well, sure. I was trying to reverse engineer the original shar files
from Google's HTML. I was frankly fairly surprised that I got as close
to perfection as I did. I realized that Google had mangled Guido's old
CWI email, but didn't worry about it. I also saw the TeX macro
mangling, but as I wasn't planning to rebuild the documentation, I
didn't worry too much about that. I expected to need a bunch of manual
patchwork to get back to something that would even compile.

It's nice to know that in this case, "the Internet never forgets."

I think to resolve this issue to the completion, and avoid possibility
of an intermediary to add any unexpected changes/mistakes to the
original sources, instead of "someone making a tarball", someone should
make a script, which reproduces making a tarball. Then such a script
can be reviewed and tarball reproduced independently (e.g., by the
admins of python.org).

That's exactly what I did, and attached it to the ticket above:
https://github.com/python/pythondotorg/issues/1734#issuecomment-781129337

For extra details, copying my comment there:

---
I attach my version of such a script (and also paste it below for
reference, but if you use it, please use the attached version to avoid
any discrepancies due to copy-paste).

The script takes care to preserve not just data, but the metadata of
the release, by setting file timestamps to the date/time of the message
which contained the 1st chunk of the shar archive. It also takes care
to create reproducible tarball, i.e. tarball archives created by
different runs of the script should byte-to-byte match each other (cf.
https://en.wikipedia.org/wiki/Reproducible_builds). Of course, that
depends on .tar and .gz formats themselves being stable (which should
be de-facto the case, and I hope their maintainers treat them as such).
As an extra measure, MD5SUMS of the individual files is also computed
and included in the tarball. Finally, the script itself is also
included, as a kind of executable documentation. That's why it's
important the script itself to be byte-perfect when recreating the
tarball. I also didn't make it executable, it should be run as sh
python-0.9.1-create-tarball.sh.

Under conditions described above, the tarball produced should have
following md5sum:

65e0c4140583c7032f35036939cf1bdd python-0.9.1.tar.gz

https://github.com/python/pythondotorg/files/6001019/python-0.9.1-create-tarball.sh.gz

The script contents for reference (do not copy-paste, use attached
version above):

#!/bin/sh
#
# This script creates fully reproducible, bytes-perfect tarball of the
# CPython 0.9.1 release (initial public release) as posted by Guido
# van Rossum to the Usenet "alt.sources" newsgroup
# (https://en.wikipedia.org/wiki/Usenet_newsgroup). This is not first
# attempt to recover the original 0.9.1 sources, but many previous
# attempts started from the Dejanews Usenet archives, later acquired
# by Google, which have whitespace issues (tabs converted to spaces).
# This script uses alternative archive source at ftp.fi.netbsd.org,
# which doesn't have whitespace issues.
#
# This script strives to produce fully reproducible archive, and for
# this explicitly sets GMT date of all files included in the archive.
# So, for as long as TAR and GZIP formats are themselves stable across
# systems, this script should produce bytes-exact archive files on any
# system.

There is already a page with Andrew's build on python.org:

https://www.python.org/download/releases/early/

but it's not linked from e.g. https://www.python.org/download/releases/

His page lists the details around making it work again:

Call me crazy, but... shouldn't they be checked in?  I thought we literally had every revision going back to day zero.  It should be duck soup to recreate the original sources--all you need is the correct revision number.

CVS to SVN to HG to GIT, oh my,

It seems to be mostly there, but the directory structure is completely
different. And the demo directory, which constitutes a significant
part of the original "distribution", is absent.

> CVS to SVN to HG to GIT, oh my,

Yeah, back in CVS times it was customary to move files around in the
repository. I’m guilty of this myself. ;)

I think to resolve this issue to the completion, and avoid possibility
of an intermediary to add any unexpected changes/mistakes to the
original sources, instead of "someone making a tarball", someone should
make a script, which reproduces making a tarball. Then such a script
can be reviewed and tarball reproduced independently (e.g., by the
admins of python.org).

That's exactly what I did, and attached it to the ticket above:
https://github.com/python/pythondotorg/issues/1734#issuecomment-781129337

For extra details, copying my comment there:

---
I attach my version of such a script (and also paste it below for
reference, but if you use it, please use the attached version to avoid
any discrepancies due to copy-paste).

I got a version to build, but what's supposed to be in patchlevel.h?  It was just an int, but that was confusing gcc.  I commented out its #include, and things seemed to work without it.  The patches I used are at https://stromberg.dnsalias.org/svn/cpythons/trunk/python0.9/exportable-patches

Sadly, it doesn't work that well with my "pythons" script (https://stromberg.dnsalias.org/~strombrg/pythons/), because 0.9.1's interpreter doesn't have a -c option.

[David Mertz]

Will someone publish an manylinux build to conda-forge (or their own channel)?

the lives and control the thoughts of homo faber. Ideas, once born,

[David Mertz]

I've provided this excellent language interpreter as a conda package.  For users of conda, you can install it (on Linux) with:

    conda install -c davidmertz python=0.9

(perhaps put it in a different environment than base).

I'm embarrassed by how much effort that took me. I used to teach conda-build at Anaconda, but I've forgotten everything about how it works. There may have been another way to do it, but what this installs uses a hack.  There might have been some other way to do this, but:

% cat `which python`
#!/bin/bash
PYTHONPATH=$CONDA_PREFIX/lib/ python-0.9.1

The manpage works though. As Skip pointed out to me privately, there are some minor limitations with this version.  E.g.:

% python
>>> import glob
>>> import sys

>>> print 'hello'
hello

>>> print 2+2
4
>>> print 2*2

Unhandled exception: run-time error: integer overflow
Stack backtrace (innermost last):
  File "<stdin>", line 1

It's easy enough to work around that though:

>>> def mult(a, b):
...     total = 0
...     for _ in range(a):
...         total = total + b
...     return total
...
>>> mult(2, 2)
4

A note to webm...@python.org from an astute user named Hiromi in Japan* referred us to Guido's shell archives for the 0.9.1 release from 1991. As that wasn't listed in the historical releases README file:

https://legacy.python.org/download/releases/src/README

I pulled the shar files (and a patch), then made a few tweaks to get it to build:

% ./python
>>> print 'hello world!'
hello world!
>>> import sys
>>> dir(sys)
['argv', 'exit', 'modules', 'path', 'ps1', 'ps2', 'stderr', 'stdin', 'stdout']
>>> sys.modules
{'builtin': <module 'builtin'>; 'sys': <module 'sys'>; '__main__': <module '__main__'>}
>>> sys.exit(0)

I then pushed the result to a Github repo:

https://github.com/smontanaro/python-0.9.1

There is a new directory named "shar" with the original files, a small README file and a compile.patch file between the original code and the runnable code.

It was a pleasant diversion for a couple hours. I was tired of shovelling snow anyway... Thank you, Hiromi.

Huh.  I wonder what's different about my build:

You can download a script to build it and a bunch of other python versions at https://stromberg.dnsalias.org/~strombrg/cpythons/

It includes all the tarballs you should need, at least for Debian. I believe I used it on CentOS recently as well.  I haven't tried it on Ubuntu in a while.

It depends on https://stromberg.dnsalias.org/~strombrg/cobble.html - and I'd like to think that's its only external dependency.

HTH

[David Mertz]

In conversation with Dan, I have fixed my conda package (but overwritten the same version).  I needed to add this to the build:

# sudo apt-get install gcc-multilib
CC='gcc -m32' make python

I don't have 32-bit headers by default anymore on my distro.  With that change, I can run:

% conda install -c davidmertz python=0.9

% python

>>> 2*2
4

Dan sent me links to some patches he developed himself, but I have not applied them.  I'm not doubting that they are good and useful, but I'm trying to make something as close as possible to what was actually first released.

Thanks. That fixes it for me as well. I never even looked at intobject.c, since it compiled out of the box, and didn't dig into it when I saw the error. Looking now, I see a 32-bit assumption:

if (x > 0x7fffffff || x < (double) (long) 0x80000000)
    return err_ovf();

With the -m32 flag, running lib/testall.py runs to completion.
