`port migrate` gets dependencies wrong

[ShadSterling (Shad Sterling)]

port migrate (and port restore --last) refuse to reinstall MPlayer after gss build fails, but installing MPlayer separately doesn't try to install gss

     - MPlayer
       Skipped because its dependency gss failed

[ShadSterling (Shad Sterling)]

same with curl

[jmroot (Joshua Root)]

Have you confirmed this with port rdependents gss after the restore of MPlayer finishes? (The gss port is now fixed so this is possible.) It's more likely that the dependencies resolve differently when restoring from the snapshot because different variants are selected.

[jmroot (Joshua Root)]

port snapshot --all --diff <snapshot-id> might also give some insights about what is different.

[ShadSterling (Shad Sterling)]

curl did have the gsasl variant, which does bring in gss; it's the only one so far to succeed

The diff doesn't show what the variants were for MPlayer or dia so I can't be sure.

For MPlayer the only variant is universal which I doubt I had enabled, and I wouldn't expect it to change dependencies.

For dia it's less involved than curl, I tried +quartz-universal with +python27, which failed on #70866, and with -python27 which failed with errors like #70804, both without attempting to install gss

The rest will have to wait for tomorrow

[jmroot (Joshua Root)]

It isn't necessarily a difference in MPlayer's variants, it could be any of its recursive dependencies. There are also dependencies that can be satisfied by multiple ports (like openssl/libressl), so things will go differently depending on which ports were installed.

[jmroot (Joshua Root)]

Replying to ShadSterling:

curl did have the gsasl variant, which does bring in gss; it's the only one so far to succeed

Curl is also a dependency of MPlayer via cmake, so it seems like it was working correctly?

[ShadSterling (Shad Sterling)]

Possibly; I tried to restore again with the fix to gss, and now it's failing to computer the dependency order at all.

How can I get port snapshot to show me each port & variants included in a snapshot?

[ShadSterling (Shad Sterling)]

Got aria2 installed

port snapshot --all --diff <snapshot-id> includes

 - aria2
   requested variants changed from '+cares+sqlite3-docs-gnutls-openssl-universal' to '+cares+docs+sqlite3-gnutls-universal'
   variants changed from '+cares+sqlite3' to '+cares+docs+sqlite3'

port rdependents gss does not include aria2

The following ports are dependent on gss:
  libgsasl
    curl
      cargo
      cmake
      git
      libgit2
        rust
      mupdf
      tesseract

Could adding +docs have removed a dependency?

[jmroot (Joshua Root)]

In the case of MPlayer it was definitely a case of its dependency curl being installed with a different variant. If you have a specific reproducible example where dependencies are calculated incorrectly, please reopen.

[ShadSterling (Shad Sterling)]

1100 ports in the migrate snapshot

38 ports failing before #70886 (gss) was fixed

17 could be installed individually (after #70886 was fixed)

14 could be installed with the same variants

9 installed with the same variants do not appear in port rdependents gss

8 installed with the same variants do not appear in port rdependents gss and were Skipped because its dependency gss failed

aria2, gnuplot, graphviz-gui, gstreamer1-gst-plugins-base, mercurial, py-jupyter_console, ruby33, youtube-dl

port rdependents gss:

The following ports are dependent on gss:
  libgsasl
    curl
      cargo
      cmake
      freeciv
      git
      jp2a
      libgit2
        rust
      lnav
      mupdf
      tesseract
      wxWidgets-3.2

Excerpts from the output of the last run of port -v -d restore --last (before #70886 was fixed):

    Migration finished with errors.
    The following ports could not be restored:

     - aria2
       Skipped because its dependency gss failed

     - gnuplot
       Skipped because its dependency gss failed
     - graphviz-gui
       Skipped because its dependency gss failed
     - gstreamer1-gst-plugins-base
       Skipped because its dependency gss failed

     - mercurial
       Skipped because its dependency gss failed

     - ruby33
       Skipped because its dependency gss failed

    The following ports could not be fully restored:

     - py-jupyter_console
       Skipped because its dependency gss failed
       state changed from 'installed' to 'inactive'

     - youtube-dl
       Skipped because its dependency gss failed
       state changed from 'installed' to 'inactive'

Excerpts from the output of port snapshot --all --diff 1 after individually reinstalling with the same variants (after #70886 was fixed):

The following ports are in the snapshot and installed, but with changes:

 - aria2
   requested variants changed from '+cares+sqlite3-docs-gnutls-openssl-universal' to '+cares+sqlite3-docs-universal'

 - gstreamer1-gst-plugins-base
   requested variants changed from '+ogg-universal-x11' to '-universal-x11'

gnuplot, graphviz-gui, mercurial, py-jupyter_console, ruby33, and youtube-dl were not included in this diff, despite being included in earlier diffs and the restore.

I'm not going to re-break my system before I even get it back to normal to try to reproduce this

[jmroot (Joshua Root)]

All of those ports have curl somewhere in their rdeps (aria2 due to the non-default cares variant). Please open a separate ticket if there is an issue with port snapshot --diff.

[ShadSterling (Shad Sterling)]

Then I guess the bug here is that rdependents output is incomplete
