S3 has memory leaks

Sending a file to S3 causes a slow memory increase toward the file size.

Copying the file back from S3 causes a slow memory increase toward the
file size.

The author of hS3 is aware of the problem, and working on it. I think I
have identified the root cause of the buffering; it's done by hS3 so it can
resend the data if S3 sends it a 307 redirect. --[[Joey]]

update on S3 memory leaks The remaining leaks are in hS3. The leak with encryption was worked around by the use of the temp file. (And was probably originally caused by gpgCipherHandle sparking a thread which kept a reference to the start of the byte string.) 2011-04-21 15:06:29 +00:00			`Sending a file to S3 causes a slow memory increase toward the file size.`
