367fd3981a Refactor config file reading. 2011-07-26 14:20:28 -07:00

7a98a496e4 Rename rand_readwrite to readwrite. 
Simpler, and all the benchmarks are pretty much as pseudorandom,
in the end; that's not a relevant characteristic. The mix of read
and write operations is.

Re-run ./bootstrap to get the s3tests-test-readwrite script
regenerated to refer to the new module name.

e17c56a714 Say ".yaml" not ".yml". This is not MS-DOS, and YML is a Yahoo XML dialect. 2011-07-26 14:20:28 -07:00

3eb53db2b3 Don't bother with fractional nanoseconds. 
<1 nanosecond is well below the threshold we can measure,
everything becomes simpler with integers, and they're easier
to skim.

f21b410154 Use a constant for nanoseconds-in-a-second. 
State it in terms of 1e9 (as int not float). My eyes get
blurry from that many zeros.

55a72f002b moved most readwrite tool command-line opts to config file

15cf598b12 readwrite tool improvements 
Now generates a list of filenames to use duing the setup, and passes this
list to the workers rather than having the workers list the bucket contents
or generate file names themselves.

Added a "warmup" stage that first writes out all the files so that content
exists for each filename.

Added setting the random seed as a command line parameter and uses this seed
for both generating the file names and the file content generator.

338728ecd2 add test_bucket_acl_no_grants 
When the owner has no grants on their bucket, they should not be able to
write to it, but still read and write the ACL. Amazon allows users to
read the bucket, and our behavior is consistent with this.

648ddbb761 Log readwrite test results in yaml. 
This temporarily removes the statistics calculation; that

71cfd4956c Move end test logic out of individual workers. 
Parent waits for the duration anyway, just make it unconditionally
kill the workers. They already had timeouts aborting them; they may
be in the middle of an operation, but we really don't care, time's up.

This also avoids oddities with the queue where there may be items
after the StopIteration.

This also avoids workers potentially not exiting within the 1-second
timeout the old code had.

dff6b568e4 Use gevent Groups to manage groups of workers.

56ff0f6374 Revert "Add assert to RandomContentFile, ensure size >= digest_size" 
This reverts commit fb8f110e69.

realistic.files was meant to work just fine with short files. Commit
91c4f88860 has a fix for the verifying
side, to support short files.

c154d98b96 Resolve the random AssertionError

fb8f110e69 Add assert to RandomContentFile, ensure size >= digest_size 
It clearly will not work to have the size smaller than the digest

Given a tuple of tuples, construct several files() generators, and
yield from those randomly. Randomness is weighted based on the number
of files remaining in each group.

b6e0287810 Add context, get_next_key, and fill_pools to s3tests.common 
context is a generic Bunch that we can store items in to be shared
across modules, without invoking the wrath of the globals -- yuck!

get_next_key will generate a sequentially numbered key for us to use

fill_pools will take a variable list of gevent.pool.Pool objects and
top them all off

91a39caf46 Fix bug where prefix was None. 
Accessing a non-constant global from another module is tricky,
as the import binds to the original object. Rebinding the name
in the original module does not change it in importers. Use a
getter as a quick workaround.
