Carthage: Xcode 10 Build Fail: missing EXPANDED_CODE_SIGN_IDENTITY

[clayellis]

• carthage install method: homebrew
• which carthage: /usr/local/bin/carthage
• carthage version: 0.29.0
• xcodebuild -version: Xcode 10.0, Build version 10L176w
• Are you using --no-build? no
• Are you using --no-use-binaries? no
• Are you using --use-submodules? no
• Are you using --cache-builds? yes
• Are you using --new-resolver? no

Actual outcome
When building in Xcode 10, the Copy Frameworks script phase fails with the error:

Environment variable not set: EXPANDED_CODE_SIGN_IDENTITY

Expected outcome
Carthage should be able to find the EXPANDED_CODE_SIGN_IDENTITY environment variable but it isn't being set by xcodebuild.

I just hit this very issue trying to compile tests for PMHTTP.

[lilyball]

This happens when compiling for macOS. Compiling for iOS Simulator worked just fine.

[clayellis]

I definitely have the correct identities on my build machine, running security find-identity -p codesigning confirms that.

[lilyball]

It appears the change here is Xcode 10 simply omits environment variables that otherwise were set to empty strings. Building the same target (for macOS) in Xcode 9.4 includes

    export EXPANDED_CODE_SIGN_IDENTITY=
    export EXPANDED_CODE_SIGN_IDENTITY_NAME=
    export EXPANDED_PROVISIONING_PROFILE=

[clayellis]

I just realized that same thing: previously they were all empty strings. Xcode 10 must be stripping them then.

[clayellis]

I'm not super familiar with all of Carthage's flags so I'm not sure if this would be a breaking change, but does anyone know if an optional check for the environment variable would be okay? It sure seems like it would be given the code that throws the error.

[lilyball]

It sure appears as though the issue is getEnvironmentVariable requires the variable to exist. If there's a variant that accepts nil variables then using it should be sufficient (well, and using flatMap instead of map).

[clayellis]

I'm going to submit a PR with an updated getEnvironmentVariable to work around the issue temporarily. I'll let you know when the fork is up @kballard.

[clayellis]

@kballard ☝️

[clayellis]

I just added some notes as to why I went with that solution, we can discuss code-specific stuff on the PR. But I think the conversation as to why this is happening should stay on the issue.

[tmspzz]

Hello,

I opened a Radar for this, please dupe it.

https://bugreport.apple.com/web/?problemID=40843445
http://www.openradar.me/radar?id=4981376604438528

Until we hear that this is intentional as @jdhealy suggested try with

EXPANDED_CODE_SIGN_IDENTITY='' carthage copy-frameworks

[lilyball]

Not setting blank environment variables seems like a perfectly fine build system change IMO. Any build script that's fine with the variable being blank should have been accepting it not being set anyway. This change certainly should slim down the build log for shell script phases that log environment variables.

[tmspzz]

Any build script that's fine with the variable being blank should have been accepting it not being set anyway.

Apparently Carthage is not fine with that and did output a meaningful error.

I am fine with the change but we're just waiting to know if the change in xcodebuild is intentional or not.

Does this work for now: EXPANDED_CODE_SIGN_IDENTITY='' carthage copy-frameworks ?

[clayellis]

@blender duped.

Updating the script in Build Phases to EXPANDED_CODE_SIGN_IDENTITY='' carthage copy-frameworks did work 👍

Until we hear back from Apple that it's an intentional change, that's a perfectly acceptable workaround. I'll try to get someone attending WWDC to ask one of the Xcode engineers during a lab.

[lilyball]

Even if it was unintentional, Carthage shouldn’t be requiring the blank variable to exist because clearly Xcode doesn’t guarantee that it’s always set (they obviously have no unit tests to ensure it’s set and no internal projects that rely on it being set). The old behavior of always setting it may have just been happenstance.

Even if Xcode does change course here, there’s simply no need for Carthage to be strict here.

[tmspzz]

@kballard I'm with you. See my review on the PR.

[jdhealy]

@kballard For users calling carthage copy-frameworks outside of Xcode (admittedly, a small fraction), that error is worthwhile in being a signpost in what’s necessary to add to achieve (for what most is the goal) of ensuring that code signing happens.

Within the scope off an Xcode build script phase, I agree with you, there’s not much utility in being strict.

With that in mind, we could consider modifying the the PR to check XCODE_PRODUCT_BUILD_VERSION in one of two ways:

• check for build versions ranges or sets that we expect to exhibit this ’blank → omitted’ behavior
• on it being set at all, ignore the error for EXPANDED_CODE_SIGN_IDENTITY not being set
  
  
  
  • which kind of makes sense, I agree: no need to be strict, even for Xcode 9 releases and below.
  
  

---

The only other scenario I could think of (not even worth considering, honestly) is if EXPANDED_CODE_SIGN_IDENTITY gets accidentally unset by a line in the script phase (but, yeah, I see virtually zero chance of this accident actually occurring in practice).

[lilyball]

@jdhealy If you want to warn people about invoking copy-frameworks outside of Xcode, then I'd look for some variable that Xcode is guaranteed to set and use that as a signal for "are we being invoked by Xcode?" If that variable is omitted, then you can check for and warn about other missing variables too. If that variable is present, then treat missing variables the same as if they're simply blank.

[lilyball]

Which is to say, I would not maintain a map of "what Xcode versions omit variables?" because that simply doesn't matter.

The scenario of someone deleting EXPANDED_CODE_SIGN_IDENTITY in a shell script phase is very unlikely to ever come up, and if it does, Carthage should respect the developer's wishes.

[jdhealy]

@kballard yeah, I think alike. That’s ‘way two’ of checking XCODE_PRODUCT_BUILD_VERSION (checking if it’s set to anything) and what I implemented in #2476.

[tmspzz]

FYI Response from Apple https://bugreport.apple.com/web/?problemID=40843445

We have determined that this is an issue for you to resolve.

There’s no difference between an empty and unset environment variable; the code shouldn’t depend on the build system to log empty/unset variables.

Please let us know whether the issue is resolved for you by updating your bug report

[mdiep]

Given that, I think we should treat unset environment variables as an empty string.

Callers should be responsible for erroring they're missing an environment variable that they require.

What do you think, @jdhealy?

[tmspzz]

FYI the report is not closed. I argued a little and they are evaluating

[tmspzz]

Issue now closed.

This issue behaves as intended based on the following:

Each shell can handle the notion of set/unset differently, so relying on that behavior is not stable. In nearly all cases, the evaluation of $MY_VAR is identical whether the var is empty or unset. Also, it looks like Carthage is already making the appropriate change.

We are now closing this bug report.

If you have questions about the resolution, or if this is still a critical issue for you, then please update your bug report with that information.

Please be sure to regularly check new Apple releases for any updates that might affect this issue.

[jdhealy]

Given that, I think we should treat unset environment variables as an empty string.

For the majority case, an unset environment variable (either ‘truly unset’ or "" → unset coalescing by Xcode) should error — especially for paths like FRAMEWORKS_FOLDER_PATH.

Only select cases (like EXPANDED_CODE_SIGN_IDENTITY) would have "" as an appropriate fallback for unset.

The case where "" is coalesced into unset by Xcode is the minority case.

[tmspzz]

@jdhealy @kballard @clayellis Please confirm we're going with this one: https://github.com/Carthage/Carthage/pull/2476 and I'll merge

[clayellis]

@blender Looks good to me 👍

[mdiep]

Fixed by #2476.
