dub run <package> should search the registry on failure #1082

wilzbach · 2017-02-23T12:15:07Z

Adds a simple fallback to dub run, s.t. the following pattern simply works:

dub run dlang-tour
dub run dfmt
dub run dscanner
dub run avgtime
...

I am not sure how we can best test this without querying the registry. Also I don't know any package that is compatible with all the compilers that DUB supports.
What would be the best strategy here?

What about making this slightly interactive and requiring the user to confirm the download. This would also be a chance to print the package description and maybe the github address, to make it less likely to make this en entry point for malicious code.

There is http://code.dlang.org/packages/gitcompatibledubpackage which is used in some of the tests already. We'd just have to add an executable configuration (in this case just a source/app.d).

Good idea - I gave it a shot. It's not perfect because without more refactoring the info payload will get downloaded twice from the registry.

I also added a test for this -> Travis will fail for a bit.

Appears that issue877-auto-download-package-if-not-found-on-error.sh is still missing an echo "y" |, or maybe a command line option that does the same. Ideally, it would also detect that stdin is empty (does that work using an EOF check?) and assume "n" in that case (would be backwards compatible and avoids unsolicited downloads).

MartinNowak · 2017-04-08T11:26:53Z

test/issue877-auto-download-package-if-not-found-on-error.sh

+set -e -o pipefail
+
+$DUB remove --version='*' cpuid > /dev/null 2>&1 || true
+$DUB run dfmt


How is that different from the test below?

MartinNowak · 2017-04-08T11:27:11Z

source/dub/commandline.d

+				if (json == Json.emptyObject)
+					return 2;
+
+				writefln("%s wasn't found online, but there's version available online:", package_name);


dfmt wasn't found online, but there's version available online???

MartinNowak · 2017-04-08T11:29:49Z

source/dub/commandline.d

+				writefln("%s wasn't found online, but there's version available online:", package_name);
+				if ("authors" in json)
+					writefln("Authors: %-(%s, %)", json["authors"][].map!(v => v.get!string));
+				if ("license" in json)


How about

if (auto p = "license" in json) writefln("Description: %s", p.get!string);

MartinNowak · 2017-04-08T11:30:54Z

source/dub/commandline.d

+				if ("version" in json)
+					writefln("Version: %s", json["version"].get!string);
+				if ("description" in json)
+					writefln("License: %s", json["license"].get!string);


Description and License are mixed up.

MartinNowak · 2017-04-08T11:31:42Z

source/dub/commandline.d

+						  default:
+						}
+					} else {
+						nb = true;


Should be the default value, no?

MartinNowak · 2017-04-08T11:33:15Z

source/dub/commandline.d

+							nb = true;
+						  case "no", "n":
+							nb = false;
+						  default:


I'd rather loop in here, than on the outside. Also allows you to drop Nullable.

MartinNowak · 2017-04-08T11:36:28Z

source/dub/commandline.d

+					logInfo("Retry with ~master...");
+					dep = Dependency("~master");
+					json = dub.info(package_name, dep, fetchOpts, supplier);
+				}


Could this maybe reuse dub.searchPackages?

MartinNowak · 2017-04-08T11:38:16Z

source/dub/commandline.d

+			auto package_name = free_args[0];
+			auto pack = dub.packageManager.getFirstPackage(package_name);
+
+			if (!pack)


Please check some --non-interactive argument as well to prevent hanging scripts.

Dub packages must first be fetched before you can run them, at least until dlang/dub#1082 is accepted.

Thanks for your pull request, @wilzbach!

wilzbach · 2017-09-14T23:01:33Z

Okay I finally found time to rebase and rework this. Thanks to @MartinNowak's feedback and the time passed since I submitted this, I managed to cut the size of this PR in half :)

This only needs a new release of gitcompatibledubpackage as dlang-community/gitcompatibledubpackage#1 isn't part of the dummy package's 1.0.2 release (@MartinNowak: how about moving this package to dlang-community?)

s-ludwig · 2017-09-14T23:04:43Z

source/dub/commandline.d

+
+				bool answer = input("Do you want to fetch %s?".format(package_name));
+				auto dep = Dependency(p.version_);
+				dub.fetch(package_name, dep, dub.defaultPlacementLocation, fetchOpts);


Nitpick: since the package doesn't exist locally, FetchOptions.forceBranchUpgrade shouldn't have an effect and FetchOptions.none would be sufficient here.

I accidentally closed this PR because I wanted to trigger a notification to Semaphore while I pushed and GitHub doesn't seem to like this (even restoring the old commit sha still doesn't allow me to reopen).

Anyway, I opened a new PR -> #1428
Sorry for the noise.
