Harshavardhana 1d8a8c63db Simplify data verification with HashReader. (#5071)
Verify() was being called by caller after the data
has been successfully read after io.EOF. This disconnection
opens a race under concurrent access to such an object.
Verification is not necessary outside of Read() call,
we can simply just do checksum verification right inside
Read() call at io.EOF.

This approach simplifies the usage.

Andreas Auernhammer 79ba4d3f33 refactor ObjectLayer PutObject and PutObjectPart (#4925)
This change refactor the ObjectLayer PutObject and PutObjectPart
functions. Instead of passing an io.Reader and a size to PUT operations
ObejectLayer expects an HashReader.
A HashReader verifies the MD5 sum (and SHA256 sum if required) of the object.
This change updates all all PutObject(Part) calls and removes unnecessary code
in all ObjectLayer implementations.

Fixes #4923

Harshavardhana d864e00e24 posix: Deprecate custom removeAll/mkdirAll implementations. (#4808)
Since go1.8 os.RemoveAll and os.MkdirAll both support long
path names i.e UNC path on windows. The code we are carrying
was directly borrowed from `pkg/os` package and doesn't need
to be in our repo anymore. As a side affect this also
addresses our codecoverage issue.

Refer #4658

Aditya Manthramurthy 32da1aa9d6 XL: Simplify heal-format operations
This is in preparation for updated admin heal API.

* Improve case analysis of healFormatXL() - fixes a case where disks
  could have unhandled errors.

* Simplify healFormatXLFreshDisks() and healFormatXLCorruptedDisks()
  to share more code and handle fewer cases for improved simplicity
  and reduced code repetition.

* Fix test cases.

Harshavardhana 075b8903d7 fs: Add safe locking semantics for `format.json` (#4523)
This patch also reverts previous changes which were
merged for migration to the newer disk format. We will
be bringing these changes in subsequent releases. But
we wish to add protection in this release such that
future release migrations are protected.

Revert "fs: Migration should handle bucketConfigs as regular objects. (#4482)"
This reverts commit 976870a391.

Revert "fs: Migrate object metadata to objects directory. (#4195)"
This reverts commit 76f4f20609.

Harshavardhana 62f8343879 Add constants for commonly used values. (#3588)
This is a consolidation effort, avoiding usage
of naked strings in codebase. Whenever possible
use constants which can be repurposed elsewhere.

This also fixes `goconst ./...` reported issues.

Harshavardhana 2d6f8153fa format: Check properly for disks in valid formats. (#3427)
There was an error in how we validated disk formats,
if one of the disk was formatted and was formatted with
FS would cause confusion and object layer would never
initialize essentially go into an infinite loop.

Validate pre-emptively and also check for FS format
properly.

Harshavardhana 6efee2072d objectLayer: Check for `format.json` in a wrapped disk. (#3311)
This is needed to validate if the `format.json` indeed exists
when a fresh node is brought online.

This wrapped implementation also connects to the remote node
by attempting a re-login. Subsequently after a successful
connect `format.json` is validated as well.

Fixes #3207

Harshavardhana 716316f711 Reduce number of envs and options from command line. (#3230)
Ref #3229

After review with @abperiasamy we decided to remove all the unnecessary options

- MINIO_BROWSER (Implemented as a security feature but now deemed obsolete
  since even if blocking access to MINIO_BROWSER, s3 API port is open)
- MINIO_CACHE_EXPIRY (Defaults to 72h)
- MINIO_MAXCONN (No one used this option and we don't test this)
- MINIO_ENABLE_FSMETA (Enable FSMETA all the time)

Remove --ignore-disks option - this option was implemented when XL layer
 would initialize the backend disks and heal them automatically to disallow
 XL accidentally using the root partition itself this option was introduced.

This behavior has been changed XL no longer automatically initializes
`format.json`  a HEAL is controlled activity, so ignore-disks is not
useful anymore. This change also addresses the problems of our documentation
going forward and keeps things simple. This patch brings in reduction of
options and defaulting them to a valid known inputs.  This patch also
serves as a guideline of limiting many ways to do the same thing.

Harshavardhana 9e2d0ac50b Move to URL based syntax formatting. (#3092)
For command line arguments we are currently following

- <node-1>:/path ... <node-n>:/path

This patch changes this to

- http://<node-1>/path ... http://<node-n>/path
