Hi!
While working on Debian's “reproducible builds” effort [1], we have
noticed that none of the octave-* packages build reproducibly.
Octave, by default, writes a timestamp to (at least) the doc-cache
file output by the "pkg install" action.
The attached patch prevents this.
It will, however, change the output of all calls to the save function.
I do not know if this will be a problem, or if this matters in practice.
Possible alternative fixes:
* Don't ship the doc-cache? Octave recommend shipping it. #37542 [2]
* Call save_header_format_string at a narrower scope, to ensure it only
changes the doc-cache.
install.m -> generate_lookfor_cache.m -> doc_cache_create.m.
* Make it possible for packages to opt-in to this fix (environment
variable, perhaps?)
Regards,
Chris
