fix file upload - consider metadata options by creating form data #500

KharitonOff · 2018-03-14T10:12:47Z

Summary

fix file upload issue, now you can upload buffer stream as expected:

let file = fs.readFileSync('../file.png')
slackClient.files.upload({ channels, file, filename: 'file.png' })

as well as proposed fix in #307:

let file = fs.readFileSync('../file.png')
slackClient.files.upload({ channels, file: {value: file, options:{filename: 'file.png'}}, filename: 'file.png' })

was this actually causing a failure? i think your change is more technically correct, but i'm wondering if you actually got a test run where the timers were so perfect that r.diff and minDiff were actually equal.

I can confirm that I've run into the issue of getting a test run where the timers matched up and a false positive was thrown--just once, but it has happened.

yes, I added this fix to the PR, because the build of my first commit broke accidentally

+          filename: 'train.png',


i was trying to avoid this usage all together, because it seems redundant to have to specify the filename twice. can you see any advantage to doing it this way?

The main advantage I see is the current implementation state of all the folks who used the old style. I don't know whether there is a need for someone to provide further attributes in the options field (e.g. contentType or knownLength)

i also want to make sure the implementation accounts for those who used the old style, but i prefer that the path we take to get there is not to redo the same hack, but to smooth out the API so that you don't need to redundantly specify the filename.

i wouldn't call it a hack if there was legitimately a use case or need for using the { value, options } format for file. i don't see any benefit from exposing contentType and/or knownLength at this time, since that only has the potential to force to incorrect values and cause the upload to fail (but I'm happy to be corrected if there is a real use case).

maybe we can channel this effort towards investigating why the following code didn't behave as we want:

node-slack-sdk/src/WebClient.ts

Lines 530 to 537 in a206c3e

// options.file = {

// // @ts-ignore

// value: options.file,

// options: {

// // @ts-ignore

// filename: options.filename,

// },

// };

AFAICT it should result in the same thing...

also, have you tried this implementation to upload actual files? i'm not 100% confident that the nock expectations are correct.

Sorry, but I don't really understand your comment... this code snippet, you mentioned above works now as well. Off course I have tried it before I've opened this PR. And the problem with it, why it didn't work before was in the implementation of

node-slack-sdk/src/WebClient.ts

Lines 556 to 561 in a206c3e

if (containsBinaryData) {

return flattened.reduce((form, [key, value]) => {

form.append(key, value);

return form;

}, new FormData());

}

I've added this part in order to provide the attribute options to the form builder.

if (key === 'file' && value.value) { form.append(key, value.value, value.options); return form; }

https://github.com/KharitonOff/node-slack-sdk/blob/45c77022a81cd2631a5a2bd3ee0dd29e401f51d7/src/WebClient.ts#L554-L563

This is actually the main goal of this PR and all other things we talked here about, were done with intention not to break the current state. As I mentioned in the PR description, you can upload files now with no need of additional/redundant information

let file = fs.readFileSync('../file.png') slackClient.files.upload({ channels, file, filename: 'file.png' })

Should i remove the 'backup' solution to restrict the file upload to only one way?

@KharitonOff thanks so much for your clarification. i missed that diff amidst the rest of the changes but i now see where the issue was before.

yes, i'd prefer removing the backup solution so that we don't unnecessarily expand the API contract. if you can do that, i'm happy to land this PR!

still not asserting that the filename field exists, and removed the comment that would remind us to improve the tests so that it is asserted. why?

sorry, I've overseen this assertion statement and felt that the fix solved the problem pointed in the comment. I'll bring your TODO and assertion back.

I've changed your test again in order to fix the build. I hope it is ok for you.
The last travis build failed because of timeout. This seems to be an occasional fail:
build for node v9 succeeds:

build for node v8 fails:

maybe the best place to override this value is in test/mocha.opts, so that it doesn't just apply to this one case. i don't see anything unique to this case that should make it run longer than the other. its my guess that Travis generally has unpredictable speed and we should make the ceiling high enough to accomodate.

Agree! I didn't find this setting before, that's why I added it only to this test.

@KharitonOff its a small world. I just noticed that you work on CLA Assistant (which we use) and you helped review an implementation for a feature i requested, way back when (cla-assistant/cla-assistant#246). 🙌

This is so great!! Extra thanks for cleaning up the style issues and some incorrect behavior in the existing tests.

I'm going to follow up with a PR that addresses the "note to self" comments above.
