also use designated names for internal
calls
- storageREST calls are storageR
- lockREST calls are lockR
- peerREST calls are just peer
Named in this fashion to facilitate wildcard matches
by having prefixes of the same name.
Additionally, also enable funcNames for generic handlers
that return errors, currently we disable '<unknown>'
In a replicated setup, when an object is updated in one cluster but
still waiting to be replicated to the other cluster, GET requests with
if-match, and range headers will likely fail. It is better to proxy
requests instead.
Also, this commit avoids printing verbose logs about precondition &
range errors.
reedsolomon/cpuid would take a long time to start up on Xen VMs with
AMD processors due to a bug in the VM CPUID implementation.
Compression upgraded for better speed/compression.
fix: change timedvalue to return previous cached value
caller can interpret the underlying error and decide
accordingly, places where we do not interpret the
errors upon timedValue.Get() - we should simply use
the previously cached value instead of returning "empty".
Bonus: remove some unused code
Add a generic handler that adds a new tracing context to the request if
tracing is enabled. Other handlers are free to modify the tracing
context to update information on the fly, such as, func name, enable
body logging etc..
With this commit, requests like this
```
curl -H "Host: ::1:3000" http://localhost:9000/
```
will be traced as well.
Directories markers are not healed when healing a new fresh disk. A
a proper fix would be moving object names encoding/decoding to erasure
object level but it is too late now since the object to set distribution is
calculated at a higher level.
It is observed in a local 8 drive system the CPU seems to be
bottlenecked at

Bonus changes:
- re-use transport for bucket replication clients, also site replication clients.
- use 32KiB buffer for all read and writes at transport layer seems to help
TLS read connections.
- Do not have 'MaxConnsPerHost' this is problematic to be used with net/http
connection pooling 'MaxIdleConnsPerHost' is enough.
This commit fixes the order of elliptic curves.
As documented by https://pkg.go.dev/crypto/tls#Config
```
// CurvePreferences contains the elliptic curves that will be used in
// an ECDHE handshake, in preference order. If empty, the default will
// be used. The client will use the first preference as the type for
// its key share in TLS 1.3. This may change in the future.
```
In general, we should prefer `X25519` over the NIST curves.

- Always reformat all disks when a new disk is detected, this will
ensure new uploads to be written in new fresh disks
- Always heal all buckets first when an erasure set started to be healed
- Use a lock to prevent two disks belonging to different nodes but in
the same erasure set to be healed in parallel
- Heal different sets in parallel
Bonus:
- Avoid logging errUnformattedDisk when a new fresh disk is inserted but
not detected by healing mechanism yet (10 seconds lag)
site replication errors were printed at
various random locations, repeatedly - this
PR attempts to remove double logging and
capture all of them at a common place.
This PR also enhances the code to show
partial success and errors as well.
`mc admin heal -r <alias>` in a multi setup pools returns incorrectly
grey objects. The reason is that erasure-server-pools.HealObject() runs
HealObject in all pools and returns the result of the first nil
error. However, in the lower erasureObject level, HealObject() returns
nil if an object does not exist + missing error in each disk of the object
in that pool, therefore confusing mc.
Make erasureObject.HealObject() to return not found error in the lower
level, so at least erasureServerPools will know what pools to ignore.
`config.ResolveConfigParam` returns the value of a configuration for any
subsystem based on checking env, config store, and default value. Also returns info
about which config source returned the value.
This is useful to return info about config params overridden via env in the user
APIs. Currently implemented only for OpenID subsystem, but will be extended for
others subsequently.
If sending a white space during a long S3 handler call fails,
the whitespace goroutine forgets to return a result to the caller.
Therefore, the complete multipart handler will be blocked.
Remember to send the header written result to the caller
or/and close the channel.
