we have a single python file that has the main function

most-wire-83210

06/20/2017, 12:30 AM

and we have another file called requirements.txt

most-wire-83210

06/20/2017, 12:32 AM

I wanted to create a pex file with those requirements in requirements.txt included and also the entry point being the main function in the single python file

most-wire-83210

06/20/2017, 12:32 AM

how do I go about doing it?

witty-crayon-22786

06/20/2017, 12:34 AM

...with pants, probably.

we cannot use the cli tool pex directly?

witty-crayon-22786

06/20/2017, 12:34 AM

*shrug. i don't know about pex's CLI args.

Is there an option to turn off zinc and just use the underlying compiler directly, forgoing incremental compilation?

happy-kitchen-89482

06/20/2017, 12:34 AM

We’re getting repeated, annoying zinc crashes

witty-crayon-22786

06/20/2017, 12:47 AM

not currently. we'd be interested in experimenting with such a thing, as our median target size drops small enough

happy-kitchen-89482

06/20/2017, 12:56 AM

Ugh

happy-kitchen-89482

06/20/2017, 12:57 AM

So we need to deal with these crashes, they are quite common

witty-crayon-22786

06/20/2017, 12:57 AM

what do they look like?

happy-kitchen-89482

06/20/2017, 12:57 AM

They look like the cause is analysis getting into a bad state

happy-kitchen-89482

06/20/2017, 12:57 AM

a repeat run of the same command invariably fixes the problem

happy-kitchen-89482

06/20/2017, 12:57 AM

until the next time

happy-kitchen-89482

06/20/2017, 12:58 AM

And the error messages are along the lines of ‘I expected this analysis field to contain something but it contains null’

@happy-kitchen-89482 : are you using an older version? ie, is it set in

//BUILD.*

happy-kitchen-89482

06/20/2017, 1:05 AM

No, we’re using the default afaict

happy-kitchen-89482

06/20/2017, 1:06 AM

And we’re on pants 1.3.0

witty-crayon-22786

06/20/2017, 1:07 AM

hm. has that one been reported on the issue tracker? we're interested in coming at this from both directions currently: 1) the ability to disable zinc entirely would be good, 2) reporting bugs upstream would be good... because the scala center folks currently have someone dedicated to it

happy-kitchen-89482

06/20/2017, 4:47 AM

I’ll see about reporting it

hi - is there a way to get the compile time jar dependencies for a target? I’m working on a task to generate eclipse project files which is different enough from the built in eclipse task. I would like to use the export of the project to do it, but from what I can tell this doesn’t respect the

strict_deps

of the targets.

jar_dependencies

of JvmTarget also doesn’t look at

strict_deps

. Is there a way to get export to match

strict_deps

or write a custom task to do something similar?

witty-crayon-22786

06/20/2017, 5:17 PM

strict_deps

is a relatively new concept... if

export

isn't matching for it, it probably should be

how do I enable better logging out of the rust engine?

witty-crayon-22786

06/20/2017, 5:45 PM

wow... sorry for the trouble.

fast-nail-55400

06/20/2017, 5:45 PM

adding -ldebug to that command only gives better logging out of the python code
