mmap-go
=======
mmap-go is a portable mmap package for the [Go programming language](http://golang.org).
It has been tested on Linux (386, amd64), OS X, and Windows (386). It should also
work on other Unix-like platforms, but hasn't been tested with them. I'm interested
to hear about the results.
I haven't been able to add more features without adding significant complexity,
so mmap-go doesn't support mprotect, mincore, and maybe a few other things.
If you're running on a Unix-like platform and need some of these features,
I suggest Gustavo Niemeyer's [gommap](http://labix.org/gommap).

// The main part of this loop is a simple copy of eight bytes at a time

// if d and d-offset are less than eight bytes apart (indicating a
// repeating pattern of length < 8), we first need to expand the pattern in
// order to get the correct results. For instance, if the buffer looks like
// this, with the eight-byte <d-offset> and <d> patterns marked as
// intervals:
//
// abxxxxxxxxxxxx
// [------] d-offset
// [------] d
//
// a single eight-byte copy from <d-offset> to <d> will repeat the pattern
// once, after which we can move <d> two bytes without moving <d-offset>:
//
// ababxxxxxxxxxx
// [------] d-offset
// [------] d
//
// and repeat the exercise until the two no longer overlap.
//
// This allows us to do very well in the special case of one single byte
// repeated many times, without taking a big hit for more general cases.
//
// The worst case of extra writing past the end of the match occurs when
// offset == 1 and length == 1; the last copy will read from byte positions
// [0..7] and write to [4..11], whereas it was only supposed to write to
// position 1. Thus, ten excess bytes.

// compressed := item* literal*
// item := literal* copy
//
// The trailing literal sequence has a space blowup of at most 62/60
// since a literal of length 60 needs one tag byte + one extra byte
// for length information.
//
// Item blowup is trickier to measure. Suppose the "copy" op copies
// 4 bytes of data. Because of a special check in the encoding code,
// we produce a 4-byte copy only if the offset is < 65536. Therefore
// the copy op takes 3 bytes to encode, and this type of item leads
// to at most the 62/60 blowup for representing literals.
//
// Suppose the "copy" op copies 5 bytes of data. If the offset is big
// enough, it will take 5 bytes to encode the copy op. Therefore the
// worst case here is a one-byte literal followed by a five-byte copy.
// That is, 6 bytes of input turn into 7 bytes of "compressed" data.
//
// This last factor dominates the blowup, so the final estimate is:

// Package snappy implements the Snappy compression format. It aims for very
// high speeds and reasonable compression.
//
// There are actually two Snappy formats: block and stream. They are related,
// but different: trying to decompress block-compressed data as a Snappy stream
// will fail, and vice versa. The block format is the Decode and Encode
// functions and the stream format is the Reader and Writer types.
//
// The block format, the more common case, is used when the complete size (the
// number of bytes) of the original data is known upfront, at the time
// compression starts. The stream format, also known as the framing format, is
// for when that isn't always true.
//
// The canonical, C++ implementation is at https://github.com/google/snappy and
// it only implements the block format.
package snappy // import "github.com/golang/snappy"

/*
Each encoded block begins with the varint-encoded length of the decoded data,
followed by a sequence of chunks. Chunks begin and end on byte boundaries. The
first byte of each chunk is broken into its 2 least and 6 most significant bits
called l and m: l ranges in [0, 4) and m ranges in [0, 64). l is the chunk tag.
Zero means a literal tag. All other values mean a copy tag.
For literal tags:
- If m < 60, the next 1 + m bytes are literal bytes.
- Otherwise, let n be the little-endian unsigned integer denoted by the next
m - 59 bytes. The next 1 + n bytes after that are literal bytes.
For copy tags, length bytes are copied from offset bytes ago, in the style of
Lempel-Ziv compression algorithms. In particular:
- For l == 1, the offset ranges in [0, 1<<11) and the length in [4, 12).
The length is 4 + the low 3 bits of m. The high 3 bits of m form bits 8-10
of the offset. The next byte is bits 0-7 of the offset.
- For l == 2, the offset ranges in [0, 1<<16) and the length in [1, 65).
The length is 1 + m. The offset is the little-endian unsigned integer
denoted by the next 2 bytes.
- For l == 3, this tag is a legacy format that is no longer issued by most
encoders. Nonetheless, the offset ranges in [0, 1<<32) and the length in
[1, 65). The length is 1 + m. The offset is the little-endian unsigned
integer denoted by the next 4 bytes.

We use GitHub to manage reviews of pull requests.
* If you have a trivial fix or improvement, go ahead and create a pull
request, addressing (with `@...`) one or more of the maintainers
(see [AUTHORS.md](AUTHORS.md)) in the description of the pull request.
* If you plan to do something more involved, first propose your ideas
in a Github issue. This will avoid unnecessary work and surely give
you and us a good deal of inspiration.
* Relevant coding style guidelines are the [Go Code Review

# Universally Unique Lexicographically Sortable Identifier

A Go port of [alizain/ulid](https://github.com/alizain/ulid) with binary format implemented.
## Background
A GUID/UUID can be suboptimal for many use-cases because:
- It isn't the most character efficient way of encoding 128 bits
- UUID v1/v2 is impractical in many environments, as it requires access to a unique, stable MAC address
- UUID v3/v5 requires a unique seed and produces randomly distributed IDs, which can cause fragmentation in many data structures
- UUID v4 provides no other information than randomness which can cause fragmentation in many data structures
A ULID however:
- Is compatible with UUID/GUID's
- 1.21e+24 unique ULIDs per millisecond (1,208,925,819,614,629,174,706,176 to be exact)
- Lexicographically sortable
- Canonically encoded as a 26 character string, as opposed to the 36 character UUID
- Uses Crockford's base32 for better efficiency and readability (5 bits per character)
- Case insensitive
- No special characters (URL safe)
- Monotonic sort order (correctly detects and handles the same millisecond)
## Install
```shell
go get github.com/oklog/ulid
```
## Usage
An ULID is constructed with a `time.Time` and an `io.Reader` entropy source.
This design allows for greater flexibility in choosing your trade-offs.
Please note that `rand.Rand` from the `math` package is *not* safe for concurrent use.
Instantiate one per long living go-routine or use a `sync.Pool` if you want to avoid the potential contention of a locked `rand.Source` as its been frequently observed in the package level functions.
```go
func ExampleULID() {
t := time.Unix(1000000, 0)
entropy := ulid.Monotonic(rand.New(rand.NewSource(t.UnixNano())), 0)
fmt.Println(ulid.MustNew(ulid.Timestamp(t), entropy))
// Output: 0000XSNJG0MQJHBF4QX1EFD6Y3
}
```
## Specification
Below is the current specification of ULID as implemented in this repository.
### Components
**Timestamp**
- 48 bits
- UNIX-time in milliseconds
- Won't run out of space till the year 10895 AD
**Entropy**
- 80 bits
- User defined entropy source.
- Monotonicity within the same millisecond with [`ulid.Monotonic`](https://godoc.org/github.com/oklog/ulid#Monotonic)
### Encoding
[Crockford's Base32](http://www.crockford.com/wrmg/base32.html) is used as shown.
This alphabet excludes the letters I, L, O, and U to avoid confusion and abuse.
```
0123456789ABCDEFGHJKMNPQRSTVWXYZ
```
### Binary Layout and Byte Order
The components are encoded as 16 octets. Each component is encoded with the Most Significant Byte first (network byte order).
```

# OpenTracing API for Go
This package is a Go platform API for OpenTracing.
## Required Reading
In order to understand the Go platform API, one must first be familiar with the
[OpenTracing project](https://opentracing.io) and
[terminology](https://opentracing.io/specification/) more specifically.
## API overview for those adding instrumentation
Everyday consumers of this `opentracing` package really only need to worry
about a couple of key abstractions: the `StartSpan` function, the `Span`
interface, and binding a `Tracer` at `main()`-time. Here are code snippets
demonstrating some important use cases.
#### Singleton initialization
The simplest starting point is `./default_tracer.go`. As early as possible, call
```go
import "github.com/opentracing/opentracing-go"
import ".../some_tracing_impl"
func main() {
opentracing.SetGlobalTracer(
// tracing impl specific:
some_tracing_impl.New(...),
)
...
}
```
#### Non-Singleton initialization
If you prefer direct control to singletons, manage ownership of the
`opentracing.Tracer` implementation explicitly.
#### Creating a Span given an existing Go `context.Context`
If you use `context.Context` in your application, OpenTracing's Go library will
happily rely on it for `Span` propagation. To start a new (blocking child)
`Span`, you can use `StartSpanFromContext`.
```go
func xyz(ctx context.Context, ...) {
...
span, ctx := opentracing.StartSpanFromContext(ctx, "operation_name")
defer span.Finish()
span.LogFields(
log.String("event", "soft error"),
log.String("type", "cache timeout"),
log.Int("waited.millis", 1500))
...
}
```
#### Starting an empty trace by creating a "root span"
It's always possible to create a "root" `Span` with no parent or other causal
reference.
```go
func xyz() {
...
sp := opentracing.StartSpan("operation_name")
defer sp.Finish()
...
}
```
#### Creating a (child) Span given an existing (parent) Span
```go
func xyz(parentSpan opentracing.Span, ...) {
...
sp := opentracing.StartSpan(
"operation_name",
opentracing.ChildOf(parentSpan.Context()))
defer sp.Finish()
...
}
```
#### Serializing to the wire
```go
func makeSomeRequest(ctx context.Context) ... {
if span := opentracing.SpanFromContext(ctx); span != nil {
httpClient := &http.Client{}
httpReq, _ := http.NewRequest("GET", "http://myservice/", nil)
// Transmit the span's TraceContext as HTTP headers on our
// outbound request.
opentracing.GlobalTracer().Inject(
span.Context(),
opentracing.HTTPHeaders,
opentracing.HTTPHeadersCarrier(httpReq.Header))
resp, err := httpClient.Do(httpReq)
...
}
...
}
```
#### Deserializing from the wire
```go
http.HandleFunc("/", func(w http.ResponseWriter, req *http.Request) {
var serverSpan opentracing.Span
appSpecificOperationName := ...
wireContext, err := opentracing.GlobalTracer().Extract(
opentracing.HTTPHeaders,
opentracing.HTTPHeadersCarrier(req.Header))
if err != nil {
// Optionally record something about err here
}
// Create the span referring to the RPC client if available.
// If wireContext == nil, a root span will be created.
serverSpan = opentracing.StartSpan(
appSpecificOperationName,
ext.RPCServerOption(wireContext))
defer serverSpan.Finish()
ctx := opentracing.ContextWithSpan(context.Background(), serverSpan)
...
}
```
#### Conditionally capture a field using `log.Noop`
In some situations, you may want to dynamically decide whether or not
to log a field. For example, you may want to capture additional data,
such as a customer ID, in non-production environments:
```go
func Customer(order *Order) log.Field {
if os.Getenv("ENVIRONMENT") == "dev" {
return log.String("customer", order.Customer.ID)
}
return log.Noop()
}
```
#### Goroutine-safety
The entire public API is goroutine-safe and does not require external
synchronization.
## API pointers for those implementing a tracing system
Tracing system implementors may be able to reuse or copy-paste-modify the `basictracer` package, found [here](https://github.com/opentracing/basictracer-go). In particular, see `basictracer.New(...)`.
## API compatibility
For the time being, "mild" backwards-incompatible changes may be made without changing the major version number. As OpenTracing and `opentracing-go` mature, backwards compatibility will become more of a priority.
## Tracer test suite
A test suite is available in the [harness](https://godoc.org/github.com/opentracing/opentracing-go/harness) package that can assist Tracer implementors to assert that their Tracer is working correctly.

copyright license to reproduce, prepare Derivative Works of,
publicly display, publicly perform, sublicense, and distribute the
Work and such Derivative Works in Source or Object form.
3. Grant of Patent License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and
(c) You must retain, in the Source form of any Derivative Works
that You distribute, all copyright, patent, trademark, and
attribution notices from the Source form of the Work,
excluding those notices that do not pertain to any part of
the Derivative Works; and
(d) If the Work includes a "NOTICE" text file as part of its
distribution, then any Derivative Works that You distribute must
include a readable copy of the attribution notices contained
within such NOTICE file, excluding those notices that do not
pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade
names, trademarks, service marks, or product names of the Licensor,
except as required for reasonable and customary use in describing the
origin of the Work and reproducing the content of the NOTICE file.
7. Disclaimer of Warranty. Unless required by applicable law or
agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the
appropriateness of using or redistributing the Work and assume any
risks associated with Your exercise of permissions under this License.
8. Limitation of Liability. In no event and under no legal theory,
whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.
