When using the stash-archive plugin (v 1.0) with Stash 2.4.1, users reported that the download button produced corrupt/invalid .ZIP files on larger repositories. Stopwatch testing indicated that the download process was
a) slow, perhaps due to the 32K buffer size, and b) consistently ending at exactly two minutes.
It is not obvious where this limit is coming from, and it may be due to Stash itself rather than the stash-archive plugin.
NOTE: It seems that version 1.1 of the plugin resolves the issue, insofar as throughput is improved. It might be that a much larger repository size could end up reproducing the issue. Stash 2.4.1 does not seem to offer upgrades for plugins through the UPM.
