ksh93/ast-open-archive

History of the AT&T ast-open software repository (including ksh93), reconstructed from various sources

Notice

This repo was last updated on 2022-02-18 with a few minor changes:

• Added recovered source code for the 2012-02-02 ast-builtin package.
• Added recovered INIT source code from complete source tarballs for the following versions:
  • 2000-10-31 93k (from Scientific Linux)
  • 2001-07-04b 93l+ (from old OpenBSD distfiles)
  • 2003-06-21 93o+ (from old OpenPKG sources)

Previous 2022-01-26 changelog

• Added recovered sourced code for INIT 2003-06-21 93o+ found on the Wayback Machine.
• Some versions imported from the old ast-open-history repo were mislabled (i.e., the git tag had the wrong version name). Additionally, some versions of ksh were reuploaded by AT&T to apply hotfixes. The following git tags were renamed to account for this:
  • 2001-07-04 -> 2001-07-04b (reference: https://web.archive.org/web/20130605185416/http://www2.research.att.com/~gsf/download/notes.html)

• Added ast-base 2008-06-24 93t (from Mandrake Linux) to the archive.

You'll need to reclone the repo because the git history was regenerated (or you can download it as a tarball).

ast-open-archive repo

This is an archive of all released versions of ast-open that I could find. Unlike the ksh93-history repo, ast-open-archive provides all of ast-open (without any build patches). Most of these versions are from Daniel Douglas's archive (see ksh93/ksh#388 and the ast-open-history repo), although that archive is missing a few versions of ksh93 and ast-base archived elsewhere.

Showing diffs between versions

To view diffs between each version of ast-open, I suggest excluding license headers from the diffs with regex. The reason for this is because the license headers for all versions from the ast-open-history repo differ from their tarball versions, which can inflate the size of diffs.

# Show all changes in ast-open 2014-06-25 (minus license header changes)
$ git show -I '^\*     ' -I '^#      ' 2014-06-25

# Show a diff of versions 2009-05-01b and 2009-05-05
$ git diff -I '^\*     ' -I '^#      ' 2009-05-01b 2009-05-05

git blame can be used to view which version of ast-open introduced or changed a line of code, e.g.:

$ git blame src/cmd/nmake/make.c
