412876ca33 Expose base parameter in s3fs_strtoofft 
This fixes a regression from ccf3e7bfa2
which caused the misparsing of octal inputs for the mp_umask and umask
flags.  It also allows some callers to be more precise about their
decimal inputs.

c596441f58 Flush file when opening second fd 
Previously when s3fs had dirty local data and an application opened a
second fd it would remove the stat cache entry, query S3 for the size
which was still zero, then reinitialize FdEntry with this incorrect
size.  Instead flush local data to S3 so this query works.  It is
possible that a more involved patch could do this with a less
heavyweight approach but this requires changing open.  This does not
completely fix git clone but allows it to proceed further.  Also make
some cache methods const-correct.  References #839.

46d79c5bc2 Issue readdir HEAD requests without batching 
Previously s3fs would issue a batch of HEAD requests and wait for all
to succeed before issuing the next batch.  Now it issues the first
batch and only waits for a single call to succeed before issuing the
next call.  This can improve performance when one call lags due to
network errors.  I measured 25% improvement with the same level of
parallelism.  This commit also reparents parallelism knobs for
consistency.  Follows on to 88cd8feb05.

fix xpath selector in bucket listing 
the original implementation in get_base_exp() depends on the order of xml return from the server.
patriotically, when listing a directory with sub directory(s), the xml document response contains more than 2 <Prefix> nodes(some of them are in <CommonPrefixes> node).
the source code arbitrarily select the first one in the documents (nodes->nodeTab[0]->xmlChildrenNode).
some s3 compatible service return the list-bucket result in different result, leading the s3fs to a wrong behavior

0e0ae38f6d Default transport to HTTPS 
This protects private data when used over the public Internet.  Users
can opt-in to unencrypted HTTP if they need additional performance on
a local network.  Fixes #282.

1ddc14d59d Changed for accepting mount options compatible with mtab - #449 2016-07-24 08:17:58 +00:00
Peter Watkins
a19206cf0f Accept mount arguments compatible with mtab 
Using "mount -a" fails for already-mounted s3fs directories,
because s3fs mount arguments don't match the form in /etc/mtab.
Calling "mount -a" should quietly succeed when a directory is
already mounted.

To fix this, accept mount commands of the form:

s3fs s3fs /srv/object-store -o bucket=mybucket

or in /etc/fstab form:

s3fs  /srv/object-store  fuse.s3fs  bucket=mybucket 0 0

This matches the form in /etc/mtab and allows "mount -a" to
work properly.

320b8e1171 Include location constraint when creating bucket 
This allows creating buckets in non-default regions.  Also improve
do_create_bucket error handling.

584ea488bf Use role name instead of profile name when iam_role=auto 
When using an instance with an IAM Role, transient credentials can be
found in http://169.254.169.254/latest/meta-data/ at
iam/security-credentials/role-name and s3fs tries to do this. However,
it is using the profile-name where role-name is needed. In many cases
the role and profile name are the same, but they are not always.

The simplest way to find the role name appears to be to GET
http://169.254.169.254/latest/meta-data/iam/security-credentials/
itself, which returns a listing of the role names for which temporary
credentials exist. (I think there will probably only be one, but we
probably want to split on newlines and take the first one here in case
that assumption is not valid). This is the approach the AWS SDK appears
to use (based on WireShark analysis).

594c9ca7d2 Skip early credential checks when iam_role=auto 
If user specifies iam_role=auto (or just iam_role), credentials will not
be loaded during early phase, so skip credential checks there.
