Hi folks,

 

 

While going through the documentation and looking at the older releases on
https://download.osgeo.org/libtiff/, I realised we could rebuild some of the
old history predating the CVS history we imported into git.  You might be
interested in:

 

*       Commits  <https://gitlab.com/libtiff/libtiff/-/commits/tiff-3.4> .
tiff-3.4 . libtiff / libtiff . GitLab
*       Commits
<https://gitlab.com/libtiff/libtiff/-/commits/tiff-3.4-iptc> . tiff-3.4-iptc
. libtiff / libtiff . GitLab
*       Commits
<https://gitlab.com/libtiff/libtiff/-/commits/tiff-3.5-oldcvs> .
tiff-3.5-oldcvs . libtiff / libtiff . GitLab
*       Commits
<https://gitlab.com/libtiff/libtiff/-/commits/tiff-3.5-newcvs> .
tiff-3.5-newcvs . libtiff / libtiff . GitLab (this is just a branch of the
existing 3.5.7 release tag)

 

I hope the authorship and dates are all OK.  I pulled out the dates using:

 

git grep "\$Header:" | sed -e 's;.*,v ;;' -e 's; [^ ][^ ]* Exp.*$;;' | cut
-d' ' -f2,3 | sort | uniq -c | tail

 

for the most part.  Timezone unlikely to be accurate since I have no idea
what they were originally, but the dates should be basically correct.
Authorship is all Sam Leffler up to 3.5.1/3.4beta37-iptc, then it's Mike
Welles. However, the email address used in these releases (changelog and
hidden symlink)  was "Michael L. Welles <[email protected]>" but the git
history is using "Mike Welles <[email protected]>".  I've used the former on
the old branches when importing the releases, but could amend them to use
the newer address at that time in the history if that's a better choice for
consistency?

 

This takes the git history all the way back to July 1995.  There is a
disconnect where the old and new history overlaps in the early 3.5 era.
There does appear to be a difference between the source releases and the
version in git, some is expanded CVS $Header tokens but there are also
content differences as well.  I'm not sure which releases were first
released from the maptools CVS (I assume 3.5.3 since it's tagged?).
However, even the 3.5.3 release has major discrepancies-including missing
ChangeLog entries, missing tiff.h (looks like old copy from CVS "Attic") and
other Makefiles and such.  The result of the disconnect is that the git
history doesn't connect through to the imported release history.  You can
connect them up using "git graft" to link up the old history if you wish.
The root commit in git looks like the 3.5.1 release?  But you could also
link up the 3.5.2 commit (untagged) to the 3.5.2 release.

 

This is, of course, a "best effort" import of what we have available and the
original history is not there.  But this does mean we have a git commit and
git tag for every release all the way back to v3.4beta018.

 

 

Kind regards,

Roger
