The object cache implementation is XL cache, which defaults
to 8GB worth of read cache. Currently GetObject() transparently
writes to this cache upon first client read and then subsequently
serves reads from the same cache.
Currently expiration is not implemented.
* Sent XML header before the first of whitespace chars
XML parsing fails in aws cli due to unexpected whitespace character. To
fix this, we send the xml header before we send the first whitespace
character, if any.
* Fix race between sendWhiteSpaceChars and completeMultiUploadpart
This function is added to extend the standard error responses.
Which is needed in some cases for example CompleteMultipartUpload
should respond with ErrPartTooSmall error when parts uploaded are
lesser than 5MB (i.e minimum allowed size per part).
Fixes#1536
Previously, checkETag didn't handle ETags with leading and trailing
double quotes. e.g "abcdef1234" == "\"abcdef1234\"" would return false.
Now, checkETag function canonicalizes the ETags passed as arguments by
removing one leading/trailing double quote.
* Added check in PutObjectPartHandler to make sure part ID does not exceed 10000. ErrInvalidMaxParts written to response if part ID exceeds the maximum value.
This patch brings in the removal of debug logging altogether, instead
we bring in the functionality of being able to trace the errors properly
pointing back to the origination of the problem.
To enable tracing you need to enable "MINIO_TRACE" set to "1" or "true"
environment variable which would print back traces whenever there is an
error which is unhandled or at the handler layer.
By default this tracing is turned off and only user level logging is
provided.
Multipart objects are kept in non hex md5sum format.
This format doesn't comply with hex, so decoding
would fail invariably.
This is not necessary to validate and its not expected
error during a CopyObject operation.
Fixes#1519
- Marker should be escaped outside in handlers.
- Delimiter should be handled outside in handlers.
- Add missing comments and change the function names.
- Handle case of 'maxKeys' when its set to '0', its a valid
case and should be treated as such.
This type of check is added for making sure that we can support
custom regions.
ListBuckets and GetBucketLocation are always "us-east-1" rest
should look for the configured region.
Fixes#1278
Signature calculation has now moved out from being a package to
top-level as a layered mechanism.
In case of payload calculation with body, go-routines are initiated
to simultaneously write and calculate shasum. Errors are sent
over the writer so that the lower layer removes the temporary files
properly.
Adds support for the following request headers:
- x-amz-copy-source-if-match
- x-amz-copy-source-if-none-match
- x-amz-copy-source-if-unmodified-since
- x-amz-copy-source-if-modified-since
Fixes#1176
This API takes input XML input in following form.
```
<?xml version="1.0" encoding="UTF-8"?>
<Delete>
<Quiet>true</Quiet>
<Object>
<Key>Key</Key>
</Object>
<Object>
<Key>Key</Key>
</Object>
...
</Delete>
```
and responds the list of successful deletes, list of errors
for all the deleted objects.
```
<?xml version="1.0" encoding="UTF-8"?>
<DeleteResult xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
<Deleted>
<Key>sample1.txt</Key>
</Deleted>
<Error>
<Key>sample2.txt</Key>
<Code>AccessDenied</Code>
<Message>Access Denied</Message>
</Error>
</DeleteResult>
```
This commit makes code cleaner and reduces the repetitions in the code
base. Specifically, it reduces the clutter in setObjectHeaders. It also
merges encodeSuccessResponse and encodeErrorResponse together because
they served no purpose differently. Finally, it adds a simple test for
generateRequestID.
Now GetObject and HeadObject both support
- If-Modified-Since, If-Unmodified-Since
- If-Match, If-None-Match
request headers.
These headers are used to further handle the responses for GetObject
and HeadObject API.
Fixes#1098
