[Glass] Install problem

Hi Dale, thanks for that. It is now installed.

I’ll see if the clients will be willing to spend the time on upgrading the Seaside version we use. That should help to avoid some problems in the future.

Regards, Gary

I was able to reproduce your problem ... when I ran my earlier test I was using an already cloned version of the project and I wasn't using the same project entry. 

The  bug was occurring because the project entry that is used to install Seaside had the pattern match in it[1] (note the 3.1.?):

repository: \'github://GsDevKit/Seaside31:3.1.?/repository\'I replaced the `3.1.? with `v3.1.4.2-gs` and the project loaded correctly from that point on. I've patched the project entry[2] up on github ... 

I recommend that you delete the stone for the failed seaside install and run the install script from scratch and let me know if you run into more problems ...

  I just ran a GsDevKit_seaside31/bin/installServerSeaside build that completed successfully, so I'm guessing that my patches to Metacello were sufficient to get past the pattern matching problem you are experiencing ... the pattern matching tests are still failing, but perhaps I was closer than I thought:) ... at this point I will take a closer look at fixing Metacello and I should be able to publish a new version later today.

    This problem showed up about 3 months ago[1][2]. Presumably github, changed their JSON api. I started work on fixing the problem[3], but got busy with working on features for the next release of GemStone and din't finish my work ... IIRC the fix would involve some additional restructuring of the JSON handling code for GemStone ...

    The issue revolves around doing pattern matching for releases, which even when working was pretty dicey, because downloading the list of tags involves using a rate-limited github api --- pattern matching has caused persistent build failures for travis builds (exceeding the rate limit), but has also caused problems with local builds if several developers are doing Seaside builds or a single developer is running debugging build problems ...

    Because of this github rate limit pain, recent versions of Seaside have removed the version pattern matching from the Metacello spec and are just using a fixed version.

    I see that you are using GsDevKit_seaside31[6] and GsDevKit/Seaside31[7], which is no longer recommended. Seaside3.1 is a pretty old version of Seaside and is no longer being ported to the latest versions of GemStone. The GsDevKit_seaside31 project was created before the main Seaside repository was moved to GitHub, but now that SeasideSt/Seaside[4] is available, the SeasideSt/Seaside project is kept up-to-date with the latest versions of GemStone ... 

    If possible you should consider migrating to a newer version of Seaside and follow these instructions[5] for installing Seaside into an existing stone. If you are using one of the more recent versions of Seaside, you will not run into this pattern matching bug...

    With that said, I understand that it is not a simple matter to just switch Seaside versions, so I will take some time today to research the possibility of patching GsDevKit_Seaside31 and GsDevKit/Seaside31 to avoid the pattern matching bug as I think it will be a quicker route to resolution.

      Hi all, we seem to have a problem installing Seaside on our server:

      when doing

          installServerSeaside -c https -z 8383 seaside_331 3.3.1

      we're getting an error with the Metacello handling of <attached .json file>.
      (see attached output log)

      It seems the headers are specified with various upper/lower cases (which is fine by the spec: RFC 7230 3.2) but in MetacelloGemstonePlatform they are expected to be of a capitalized style case. Hence the lookup of 'Status' is failing since the actual header specifies 'status'. 

      Guess this particular JSON response has changed at some point (it's been a few years since our last install).

      Hope someone can help.

      Regards, Gary
