Description akihiko.odaki.4i 2016-08-17 00:22:31 UTC
Commit 2956811709c5481af73a864044270fac0cefc141 (pull request #162) breaks build on Linux.
It is caused by the absence of build bundle for Linux.
Comment 1 Jonathan Pryor 2016-08-17 01:19:16 UTC
1. Linux does not yet reliably build, in that the Jenkins+Linux bot doesn't actually build xamarin-android. (It fails when trying to build the cross-compilers because of issues with CppSharp.)

2. How *precisely* does this break the build? What is the error? What is the diagnostic build output?

The bundle is intended to be *optional*, because every time we bump mono, there won't be a pre-existing bundle, so it will *always* "fail," at which point it *should* "fall back" and rebuild all of mono. (The bundle would be *created* in that instance, then uploaded via Jenkins, and the *following* build would get the bundle.)
Comment 2 akihiko.odaki.4i 2016-08-17 02:31:10 UTC
1. For your information, it is reliable as my first build on openSUSE (even not Ubuntu) was sucessful just with a libzip error. I suspect your building environment is broken somehow.

2. Sorry but I have not kept the log. But I remember that it tries to download https://xamjenkinsartifact.blob.core.windows.net/xamarin-android/xamarin-android/bin/Debug/bundle-v2-Debug-Linux-libzip=1d8b1ac,llvm=8b1520c,mono=2c13a95.zip and gets a XML file:

<?xml version="1.0" encoding="utf-8"?><Error><Code>BlobNotFound</Code><Message>The specified blob does not exist.</Message></Error>

The SystemUnzip task in _ExtractBundle tries to extract and fails without giving any details.

I'll build the latest one again later (Now I'm building f22f2f23964bf6cdcee52a6797fb9374aa71499b, which doesn't have the bug, so it takes while.)

> it tries to download

That is correct.

> gets a XML file:

That is expected.

> The SystemUnzip task in _ExtractBundle tries to extract and fails

How does it fail? The <SystemUnzip/> task *ignores all errors*:


Note that the Process.ExitCode value is not used.

Without additional log output, I can't reason about how something that can't possibly fail is failing.
Comment 4 akihiko.odaki.4i 2016-08-18 02:17:09 UTC
Found that my `unzip` binary and fixed by altering it.
Sorry for having bothered. I'll close this issue.
Comment 5 akihiko.odaki.4i 2016-08-18 02:17:42 UTC
I mean my unzip was broken.
