[Monotone-devel] Automate stdio chunk size

[Thomas Moschny]

Hi all,

Currently, the automation stdio interface emits all data in chunks that do not 
exceed 1024 byte in size. This value was initially choosen somewhat randomly, 
but seems to be way too low.

Frontends like ViewMTN, Lara, Guitone, or TracMonotone make heavy use of the 
automation interface and thus could benefit from an increased chunk size.

For example, after setting the chunk size to 1M, reading mtn's ChangeLog 
through 'automate get_file' took roughly 1/10 of the time it took before.

So are there any objections against setting constants::automate_stdio_size to, 
say, 1MB? Is there anyone('s application) depending on smaller chunks? Should 
we increase the automate format version number?

Regards,
Thomas
