In the Free Pascal stack, it is common to have .ppu files. Consider them sort of binary header files. Unfortunately, these files contain the timestamp of the source file. This is undesirable because when these files are patched, the timestamp of the build is stored in those ppu files and so: 1) the build becomes unreproducible¹ 2) reverse dependent packages think the source was updated and will require a rebuild of the source To circumvent this I am adding a helper function to the fpc package (see discussions on the pascal-devel list²) to store timestamps in the debian packaging and use those to force the timestamps to something resonable. I intent to store those timestamps in debian/source/timestamps. I think that is a resonable place, so please don't error out on it in unknown-file-in-debian-source. Thanks for lintian.

tags 825222 + moreinfo thanks Hi Paul, Why not debian/timestamps? In a de facto sense, it seems like debian/source is "reserved" for the dpkg source format. Regards,
Hi Because there are already so many files in debian/ and I liked the idea because it manipulates the source (like a patch). Anyways, the "I intend to" ship has sailed. Multiple packages now use fp-fix-timestamps and I don't think it is worth the hassle of changing fp-fix-timestamps to move the location (and be backwards compatible in a smart way) and adapt those packages. Overriding lintian (as those packages now do) is easier. Paul
tags 825222 + wontfix thanks Hi Paul, Whilst I understand what you mean, I'm not completely convinced :) I mean, almost everything under debian/ "manipulates the source" and, again, the "source" subdirectory is — at least to me — de facto reserved for the source format in a dpkg sense. I'm thus marking this at wontfix; feel free to continue to use your overrides [0]. [0] https://lintian.debian.org/tags/unknown-file-in-debian-source.html Regards,

Control: reopen -1 Hi Dear Lintian maintainer, I recently was interested in solving Lintian errors on FPC and friends and got pointed to this ticket. I tend to agree with Paul that the timestamps file is better located in debian/source folder and would lobby for that. Can you please reassess this request?
Hi, Abou Al Montacir wrote: https://codesearch.debian.net/search?q=2022+path%3Adebian%2Fsource%2Ftimestamps&literal=1 and it seems that exactly 2 source packages (fpc and lazarus) are using this. Just affecting two packages is IMHO a valid case for lintian overrides. It's though a small change with practically no chance for false positives, so I'm no directly opposed to implementing it. I though wonder: Are more packages expected to use that? I mean, the initial bug report ist from 2016 and I only see two packages using it. This seems to be the wrong audience for a discussion about the location of that file. Such a discussion should come _before_ Lintian is asked to implement something. Regards, Axel
Hi Alex, https://codesearch.debian.net/search?q=2022+path%3Adebian%2Fsource%2Ftimestamps& literal=1 Yes indeed, only tow packages for now are using this file, but theoretically any package built by FPC may need this. I may agree, but I failed to find the right syntax to override this error. There seem also 9 packages they do the same according to https://lintian.debian.org/tags/unknown-file-in-debian-source So are you sur the override is working, and if yes, how to do it. We tried https://sources.debian.org/src/fpc/3.2.2%2Bdfsg- 18/debian/source/lintian-overrides/ but also several other syntaxes and it fails. It seems no package managed to override it as far as I can search. I do Agree here about what you said, but we should just know how to override it, if ever possible.

Hi Abou, the syntax is just to have the error string, and nothing else on the line, ie. # In 3.0.0+dfsg-5 elbrus added fp-fix-timestamps that expects d/source/timestamps # lintian bug: http://bugs.debian.org/825222 unknown-file-in-debian-source Cheers, Peter
