Conan: Build from package source broken in 1.5.0

[KrFe]

Conan 1.5.0 on Centos 7 with manual call to build script

Hi,

I have several packages which are stored remotely along with their sources and every time I build my local packages those packages being downloaded and the sources are compiled. Since the 1.5.0 release this is no longer working. The build fails with the following message

ERROR: MyApp/0.3.1@deployment/stable: Error in build() method, line 15
self.build_qmake()
FileNotFoundError: [Errno 2] No such file or directory: '/home/KrFe/.conan/data/MyApp/0.3.1/deployment/stable/build/5f1f71e5f81572eb63e3ce82c8c876a9e189d77b/modules/MyApp/projects/MyApp/conanbuildinfo.pri'

From the debug logging I learned the download of the sources was successful as was unzipping them. But still, the relevant directories

/home/KrFe/.conan/data/MyApp/0.3.1/deployment/stable/source

and

/home/KrFe/.conan/data/MyApp/0.3.1/deployment/stable/export_source

are empty.

To be precise the problem I am facing was introduced with commit 0388f5a3a256b14b54e975e7e0651ed10528b38f and especially the changes to the _merge_directories_ method in _source.py_. In my case the structure within the downloaded source tgz looks like

export_source/include
export_source/modules
export_source/resources

Meaning only folder and no plain files on the top level. Thus the following line
dirs[:] = [d for d in dirs if not is_excluded(src_dir, d)]
in above mentioned method prevents copying the subdirectories. Commenting out this line seems to work for me.

From the release notes I could not find any hint what I would have to change in order to make it work with 1.5.0 version of conan. If I am doing something wrong or if you need additional information please let me know.

It looks like a bug. We will try to release a minor version asap. Thanks for reporting.

Hi, I'm not able to reproduce the issue. Could you specify if you are using:

• [ ] exports_sources in the recipe
• [ ] exports in the recipe
• [ ] source() method in the recipe

Could you provide also the whole output? I would need also the conan commands you are running.

[KrFe]

Hi, I am using exports_sources in the recipe. From my understanding pulling the sources from remote is key.
The above error output is all I can see. But I instrumenting the code showed a first call to the merge method during installation of the package. In this step al data is moved from

MyApp/0.3.1/deployment/stable/export_source/.c_src

to

MyApp/0.3.1/deployment/stable/export_source/.

And then in a second call during the configuration step the sources are moved from

MyApp/0.3.1/deployment/stable/export_source/

to

MyApp/0.3.1/deployment/stable/source

If it helps my call to conan is
conan install MyApp/0.3.1@deployment/stable --build without having anything from this package in my conan cache.

Do you know which Conan version did you use to create these packages? the .c_src folder is something pre-1.0, like a year ago deprecated. Thanks for the info, let's check if I can reproduce now the issue and we can find a fix for the old packages layout.

[KrFe]

I do not know the exact version but it was for sure pre 1.0.0. The package has been generated last September with a rather new version at that time. Unfortunately I could not find any metadata in the package telling the exact version.

Issue reproduced and fixed at https://github.com/conan-io/conan/pull/3169
It will be released probably later today.

[KrFe]

Thank you very much for the very swift solution. I am happily awaiting the new version.

[lasote]

Hi again, we couldn't release today. It will need to wait for Friday morning, sorry for the delay. 😞

[lasote]

Finally, we made it. 1.5.2 is released. Let me know if you have any issue

[KrFe]

Thanks again. I just ran my test case and all is working fine with the new release.
