Hello,

We just tried upgrading django-pipeline from version 1.3.25 to 1.4.x (multiple minor versions tested, including latest: 1.4.6). Every request rendering static files went from 0.5 sec to about 20 secs to render.

We tried to debug what led to this increase but could not find it. After downgrading to 1.3 the load times were again at 0.5 secs per page.

I could swear this worked in 1.1.27...

When any of my less files specify background: url(''), the url is relative assuming that all compressed CSS will end up in css/*.css, and therefore the image urls being with '../img/'.

However, it seems that pipeline has passed paths off to django staticfiles that are all relative to their original less files, which leads to the image not being found:

No to go figure out if/where this ever worked...

If I have a file, 'foo.coffee', when I reference that file through the tag, it creates a file next to it called 'foo.js'. The problem with this is it makes it very difficult to have a version control system ignore these files. It is very unlikely that I would want to blanket ignore .css or .js files, so that isn't an option. Instead, I'm left ignoring files individually when I add a new less or coffee file.

It would be nice if pipeline placed the files in their own directory, so I could blanket ignore that directory. As an example, if I have '{static}/foo/bar.coffee', pipeline could place the compiled file in '{static}/{pipelined}/foo/bar.js', where "pipelined" could be a configurable setting.

https://github.com/cyberdelia/django-pipeline/blob/master/pipeline/storage.py#L89 <- bug here

path is string and os.path.dirname(name) is string too.

Searching substring in this case is so confusing - need more complicated logic.

I'm running django-pipeline version 1.1.22 (latest), and the following isn't working yet in .less files:

 @import "bootstrap-1.4/bootstrap.less";

The reason one would do this would be to include the Less library and be able to predefine variables and be able to use the mixins exposed by the library in one's own Less code. For instance:

@basefont: 14px; /* in bootstrap, it's 13 by default, so we override it before it's imported */

@import "bootstrap-1.4/bootstrap.less";

.ghostly { /* we use bootstrap's defined .opacity mixin to create this effect. */
    .opacity(90);
}

Currently, this doesn't work and yields:

In large projects that use dozens of third-party libraries, invariably, some library will reference a url(../../..somefile) which doesn't exist. When running manage.py collectstatic with django-pipeline, this will result in an incredibly unhelpful error like:

ValueError: The file 'tinymce/js/tinymce/plugins/compat3x/img/icons.gif' could not be found with <pipeline.storage.PipelineCachedStorage object at 0x1ca6750>.

Not only does pipeline not mention which file attempts to include this file, searching for img/icons.gif myself results in 42 matches. Even if I could locate the issue, I can't easily fix the missing file, since it's a third-party library. This means pipeline is effectively blocking all my deployments because of a missing file I don't even use.

Ideally, pipeline should report which resource is referencing a missing file and allow specifying an option to ignore it. This is very similar to the https://github.com/adamcharnock/django-pipeline-forgiving fork, although I think this would be a good idea for the main branch.

I'm using the following static storage:

class S3PipelineStorage(PipelineMixin, S3BotoStorage):
    """S3 storage with pipeline magic"""
    pass

Which is almost the same as the one from pipeline docs (even simpler because it doesnt use CachedFilesMixin) . It's fine with 1.3.x but breaks with 1.4.2 because it tries to run sass compiler using absolute path from s3. S3BotoStorage doesn't support absolute paths and throws this long exception:

The only way I have found to continue is to restart the vagrant box that I am developing on.

I'm having the following problem. Not sure if it's a misconfiguration on my end or a bug.

I'm using Bower to install some components. I've added to STATICFILES_DIRS the directory where the components are installed.

Here are some relevant parts from settings.py

STATICFILES_FINDERS = (
    'pipeline.finders.AppDirectoriesFinder',
    'pipeline.finders.FileSystemFinder',
    'pipeline.finders.PipelineFinder',
    'pipeline.finders.CachedFileFinder',
)
STATICFILES_STORAGE = 'pipeline.storage.PipelineCachedStorage'
DEBUG = False

When I run collectstatic, I get the following error:

AttributeError: 'CachedFileFinder' object has no attribute 'storages'

However, If I remove CachedFileFinder, collectstatic works fine.

I've begun implementing Pipeline in our app. I've added the middleware, items to the requirements.txt file, the compressor variable, and the PIPELINE_JS object.

PIPELINE_JS = {
    'activity': {
        'source_filenames': (
            'assets/js/libs/src/core.libs.js',
            'assets/js/libs/src/datepicker.js',
        ),
        'output_filename': 'assets/js/libs/activity.js',
    }
}

I've included the template tag on the page, and output the tag call like so:

{% compressed_js 'activity' %}

The page loads without error, but nothing appears to be happening. I wanted to make sure something should be happening at this point. I don't see any outputted files, and viewing the rendered source of the page shows an empty line where the call to the template was.

So what should I expect is happening?

Also, as a side note, it would be AWESOME if you could include a super simple app using pipeline as a demo. Something that users could download and run locally to see what happens.

Looking forward to your response.

When executing collectstatic django-pipeline does not raise an error if a file defined in PIPELINE config is not found. Is this on purpose? Do I miss a settings? I would like to get an error if file which should be compiled does not exist.

Only a small change was required in the tests to handle this change about removing the type="text/css" attributes for CSS link tags:

It might make sense when releasing a new version to drop support for Python 3.6 and Django 2.2, 3.0 and 3.1 since they have all reached end of life. If you want I can push that in this PR or seperately

collectstatic static fails with the project_infile variable in the compile_file method because the finder looks for static files in the static directories not from static_root.

We had to upgrade django-pipeline from 1.6.14 to at least 2.0.7 since we are currently in the process of upgrading django to version 3.2. After we made the update, our static files were not behaving the same anymore (css not loading). After a few days of investigating I saw that the infile parameter that is passed into the compile_file function in the LessCompiler class were not the same as the value we usually got before we made the update.

Seems like the infile value comes from compile function on the Compiler class in the init file.

    def compile(self, paths, compiler_options={}, force=False):
        def _compile(input_path):
            for compiler in self.compilers:
                compiler = compiler(verbose=self.verbose, storage=self.storage)
                if compiler.match_file(input_path):
                    try:
                        infile = self.storage.path(input_path)
                    except NotImplementedError:
                        infile = finders.find(input_path)
                    project_infile = finders.find(input_path)
                    outfile = compiler.output_path(infile, compiler.output_extension)
                    outdated = compiler.is_outdated(project_infile, outfile)
                    compiler.compile_file(project_infile, outfile,
                                          outdated=outdated, force=force,
                                          **compiler_options)

                    return compiler.output_path(input_path, compiler.output_extension)
            else:
                return input_path

I see the infile value is never passed into the compile_file function. No matter what happens in the try except, another variable called project_infile is created underneath and passed to compile_file, which in our case has the wrong value. Infile has the correct value. On the older version that we used the project_infile didnt exist and the infile value was passed to compile_file. Thank you in advance.

This is a feature request to add self.request to context in render_js on JavascriptNode.

This would be handy for cases where request context variables need to be rendered in the js template, for example, with django-csp you would be able to add a nonce in a custom template without having to extend JavascriptNode and writing a new tag to use it.

My suggestion is to add a key to extra_context which you can declare in settings with a boolean value that defaults to false. If true it adds self.request to context which will then be usable in the template.

If it's something anybody else is interested in, I could create a pull request for it.
