Sync hangs, and sync verbose crashes

[drpepper]

When I run --sync, it hangs at 100%

|....:....|....:....|....:....|....:....|....:....| 100.0% 

And when I run --sync --verbose:

$ npmd --sync --verbose
syncing...

undefined:1

I'm on OSX 10.9.1, node v0.10.22.

That isn't hanging, it's still connected and getting updates live.

Hmm, what could be changed to make that more obvious?

Unfortunately, I don't have time to work on this right now, but when I do I'll investigate
--verbose mode.

Oh, ok. So it's npmd --sync that we're supposed to be running in the background? Just updating the README would help to understand that. Another possibility would be to add a flag like --sync-once that quits when it reaches 100% .

Another idea: when it reaches 100% you could write something like "Waiting for more updates..." on the next line.

[dominictarr]

Ah, got it. Okay, I've fixed the readme. thanks for your feedback, this has been a really hard "bug" to diagnose, I've answered lots of issues where someone has gotten the wrong impression about this feature. I think we got it now though!

npmd sync (without -- also works) recovers if it crashes, so you can just stop it when you get to 100 and use the data that is already in the database.

I try installing npmd every month or so, and the npmd sync step never seems to work/finish. Here's what it does today:

$ which npmd
/Users/zeke/.nvm/v0.10.26/bin/npmd

$ npmd -v
0.20.2

$ npmd sync
connected to npm registry!!!

|....:....|....:....|....:....|....:....|....:....| 0.0%   

^ twenty minutes later, still at 0.0%

[dominictarr]

some npm stuff has changed because of the recent changes to how the npm registry works.
I just pushed 0.20.3
can you try that?

hopefully I'll get time to work on this again soon!

[zeke]

So far so good. Thanks!

[dominictarr]

awesome!
