Flags like `json, config-dir, quiet` are now honored even if they are
between minio and gateway in the cli, like, `minio --json gateway s3`.
Fixes#5403
Stable sort is needed when we are sorting based on two or more
distinct elements. When equal elements are indistinguishable,
such as with integers, or more generally, any data where the
entire element is the key like `PartNumber`, stability is not
an issue.
Refactor such that metadata and etag are
combined to a single argument `srcInfo`.
This is a precursor change for #5544 making
it easier for us to provide encryption/decryption
functions.
Delete & Multi Delete API should not try to remove the directory content.
The only permitted case is with zero size object with a trailing slash
in its name.
MaxIdleConns limits the total number of connections
kept in the pool for re-use. In addition, MaxIdleConnsPerHost
limits the number for a single host. Since minio gateways
usually connect to the same host, setting `MaxIdleConns = 100`
won't really have much of an impact since the idle connection
pool is limited to 2 anyway.
Now, with the pool set to a limit of 2, and when using
the client heavily from 2+ goroutines, the `http.Transport`
will open a connection, use it, then try to return it to
the idle-pool which often fails since there's a limit of 2.
So it's going to close the connection and new ones will be
opened on demand again, many of which get closed soon after
being used. Since those connections/sockets don't disappear
from the OS immediately, use `MaxIdleConnsPerHost = 100`
which fixes this problem.
Overwriting files is allowed, but since the introduction of
the object directory, we will aslo need to allow overwriting
an empty directory. Putting twice the same object directory
won't fail with 403 error anymore.
TestNewWebHookNotify wasn't passing in my local machine. The reason is
that the test expects the POST handler (as a webhook endpoint) is always
running on port 80, which is not always the case.
This PR implements an object layer which
combines input erasure sets of XL layers
into a unified namespace.
This object layer extends the existing
erasure coded implementation, it is assumed
in this design that providing > 16 disks is
a static configuration as well i.e if you started
the setup with 32 disks with 4 sets 8 disks per
pack then you would need to provide 4 sets always.
Some design details and restrictions:
- Objects are distributed using consistent ordering
to a unique erasure coded layer.
- Each pack has its own dsync so locks are synchronized
properly at pack (erasure layer).
- Each pack still has a maximum of 16 disks
requirement, you can start with multiple
such sets statically.
- Static sets set of disks and cannot be
changed, there is no elastic expansion allowed.
- Static sets set of disks and cannot be
changed, there is no elastic removal allowed.
- ListObjects() across sets can be noticeably
slower since List happens on all servers,
and is merged at this sets layer.

Since we do not encrypt directories we don't need to send
errors with encryption headers when the directory doesn't
have encryption metadata.
Continuation PR from 4ca10479b5
It can happen such that one of the disks that was down would
return 'errDiskNotFound' but the err is preserved due to
loop shadowing which leads to issues when healing the bucket.
This change adds an object size check such that the server does not
encrypt empty objects (typically folders) for SSE-C. The server still
returns SSE-C headers but the object is not encrypted since there is no
point to encrypt such objects.
Fixes#5493
Currently minio master requires 4 servers, we
have decided to run on a minimum of 2 servers
instead - fixes a regression from previous
releases where 3 server setups were supported.
This PR brings semver capabilities in our RPC layer to
ensure that we can upgrade the servers in rolling fashion
while keeping I/O in progress. This is only a framework change
the functionality remains the same as such and we do not
have any special API changes for now. But in future when
we bring in API changes we will be able to upgrade servers
without a downtime.
Additional change in this PR is to not abort when serverVersions
mismatch in a distributed cluster, instead wait for the quorum
treat the situation as if the server is down. This allows
for administrator to properly upgrade all the servers in the cluster.
Fixes#5393
in-memory caching cannot be cleanly implemented
without the access to GC which Go doesn't naturally
provide. At times we have seen that object caching
is more of an hindrance rather than a boon for
our use cases.
Removing it completely from our implementation
related to #5160 and #5182
This is a generic minimum value. The current reason is to support
Azure blob storage accounts name whose length is less than 5. 3 is the
minimum length for Azure.
Check if the storage class is set in an
non XL setup instead of relying on `globalEndpoints`
value. Also converge the checks for both SS
and RRS parity configuration.
This PR also removes redundant `tt.name` in all
test cases, since each testcase doesn't need to
be numbered explicitly they are numbered implicitly.
* Update the GetConfig admin API to use the latest version of
configuration, along with fixes to the corresponding RPCs.
* Remove mutex inside the configuration struct, and inside
notification struct.
* Use global config mutex where needed.
* Add `serverConfig.ConfigDiff()` that provides a more granular diff
of what is different between two configurations.
This change adds documentation about PKCS-8 vs PKCS-1 pitfalls. It
also provides a command to convert encrypted PKCS-8 RSA keys to
encrypted PKCS-1 RSA keys.
