Once logged in, they will be authenticated.\n\tMethodWebCache\n\n\t\/\/ MethodWebLogin requires the user login to Ava on the web interface\n\t\/\/ using their username and password.

Select the LOWEST\n\/\/ level of authentication you'll allow based on a tolerance for fraud weighed\n\/\/ against the convenience of the user experience. Methods are organized in\n\/\/ least-secure to most-secure order. Therefore, MethodZip will allow any auth\n\/\/ method, whereas MethodWebCache will only allow MethodWebCache and above. Ava\n\/\/ will IMPROVE the quality of the authentication automatically whenever\n\/\/ possible, selecting the highest authentication method for which the user has\n\/\/ recently authenticated.

A client observes timestamps captured locally to\n\/\/ infer the state of the leader election. Thus the implementation is tolerant\n\/\/ to arbitrary clock skew, but is not tolerant to arbitrary clock skew rate.\n\/\/\n\/\/ However the level of tolerance to skew rate can be configured by setting\n\/\/ RenewDeadline and LeaseDuration appropriately. The tolerance expressed as a\n\/\/ maximum tolerated ratio of time passed on the fastest node to time passed on\n\/\/ the slowest node can be approximately achieved with a configuration that sets\n\/\/ the same ratio of LeaseDuration to RenewDeadline. For example if a user wanted\n\/\/ to tolerate some nodes progressing forward in time twice as fast as other nodes,\n\/\/ the user could set LeaseDuration to 60 seconds and RenewDeadline to 30 seconds.\n\/\/\n\/\/ While not required, some method of clock synchronization between nodes in the\n\/\/ cluster is highly recommended. It's important to keep in mind when configuring\n\/\/ this client that the tolerance to skew rate varies inversely to master\n\/\/ availability.\n\/\/\n\/\/ Larger clusters often have a more lenient SLA for API latency. This should be\n\/\/ taken into account when configuring the client. The rate of leader transistions\n\/\/ should be monitored and RetryPeriod and LeaseDuration should be increased\n\/\/ until the rate is stable and acceptably low. It's important to keep in mind\n\/\/ when configuring this client that the tolerance to API latency varies inversely\n\/\/ to master availability.\n\/\/\n\/\/ DISCLAIMER: this is an alpha API. This library will likely change significantly\n\/\/ or even be removed entirely in subsequent releases.

A client observes timestamps captured locally to\n\/\/ infer the state of the leader election. Thus the implementation is tolerant\n\/\/ to arbitrary clock skew, but is not tolerant to arbitrary clock skew rate.\n\/\/\n\/\/ However the level of tolerance to skew rate can be configured by setting\n\/\/ RenewDeadline and LeaseDuration appropriately. The tolerance expressed as a\n\/\/ maximum tolerated ratio of time passed on the fastest node to time passed on\n\/\/ the slowest node can be approximately achieved with a configuration that sets\n\/\/ the same ratio of LeaseDuration to RenewDeadline. For example if a user wanted\n\/\/ to tolerate some nodes progressing forward in time twice as fast as other nodes,\n\/\/ the user could set LeaseDuration to 60 seconds and RenewDeadline to 30 seconds.\n\/\/\n\/\/ While not required, some method of clock synchronization between nodes in the\n\/\/ cluster is highly recommended. It's important to keep in mind when configuring\n\/\/ this client that the tolerance to skew rate varies inversely to master\n\/\/ availability.\n\/\/\n\/\/ Larger clusters often have a more lenient SLA for API latency. This should be\n\/\/ taken into account when configuring the client. The rate of leader transistions\n\/\/ should be monitored and RetryPeriod and LeaseDuration should be increased\n\/\/ until the rate is stable and acceptably low. It's important to keep in mind\n\/\/ when configuring this client that the tolerance to API latency varies inversely\n\/\/ to master availability.\n\/\/\n\/\/ DISCLAIMER: this is an alpha API.

Unmarshal uses a case-insensitive\n\/\/ comparison to match XML element names to struct field names.\n\/\/\n\/\/ Unmarshal maps an XML element to a struct using the following rules:\n\/\/\n\/\/   * If the struct has a field named XMLName of type xml.Name,\n\/\/      Unmarshal records the element name in that field.\n\/\/\n\/\/   * If the XMLName field has an associated tag string of the form\n\/\/      \"tag\" or \"namespace-URL tag\", the XML element must have\n\/\/      the given tag (and, optionally, name space) or else Unmarshal\n\/\/      returns an error.\n\/\/\n\/\/   * If the XML element has an attribute whose name matches a\n\/\/      struct field of type string with tag \"attr\", Unmarshal records\n\/\/      the attribute value in that field.\n\/\/\n\/\/   * If the XML element contains character data, that data is\n\/\/      accumulated in the first struct field that has tag \"chardata\".\n\/\/      The struct field may have type []byte or string.\n\/\/      If there is no such field, the character data is discarded.\n\/\/\n\/\/   * If the XML element contains a sub-element whose name\n\/\/      matches a struct field whose tag is neither \"attr\" nor \"chardata\",\n\/\/      Unmarshal maps the sub-element to that struct field.\n\/\/      Otherwise, if the struct has a field named Any, unmarshal\n\/\/      maps the sub-element to that struct field.\n\/\/\n\/\/ Unmarshal maps an XML element to a string or []byte by saving the\n\/\/ concatenation of that elements character data in the string or []byte.\n\/\/\n\/\/ Unmarshal maps an XML element to a slice by extending the length\n\/\/ of the slice and mapping the element to the newly created value.\n\/\/\n\/\/ Unmarshal maps an XML element to a bool by setting the bool to true.\n\/\/\n\/\/ Unmarshal maps an XML element to an xml.Name by recording the\n\/\/ element name.\n\/\/\n\/\/ Unmarshal maps an XML element to a pointer by setting the pointer\n\/\/ to a freshly allocated value and then mapping the element to that value.\n\/\/\nfunc Unmarshal(r io.Reader, val interface{}) os.Error {\n\tv, ok := reflect.NewValue(val).(*reflect.PtrValue)\n\tif !ok {\n\t\treturn os.NewError(\"non-pointer passed to Unmarshal\")\n\t}\n\tp := NewParser(r)\n\telem := v.Elem()\n\terr := p.unmarshal(elem, nil)\n\tif err != nil {\n\t\treturn err\n\t}\n\treturn nil\n}\n\n\/\/ An UnmarshalError represents an error in the unmarshalling process.\ntype UnmarshalError string\n\nfunc (e UnmarshalError) String() string { return string(e) }\n\n\/\/ The Parser's Unmarshal method is like xml.Unmarshal\n\/\/ except that it can be passed a pointer to the initial start element,\n\/\/ useful when a client reads some raw XML tokens itself\n\/\/ but also defers to Unmarshal for some elements.\n\/\/ Passing a nil start element indicates that Unmarshal should\n\/\/ read the token stream to find the start element.\nfunc (p *Parser) Unmarshal(val interface{}, start *StartElement) os.Error {\n\tv, ok := reflect.NewValue(val).(*reflect.PtrValue)\n\tif !ok {\n\t\treturn os.NewError(\"non-pointer passed to Unmarshal\")\n\t}\n\treturn p.unmarshal(v.Elem(), start)\n}\n\n\/\/ fieldName strips invalid characters from an XML name\n\/\/ to create a valid Go struct name.

In essence, it provides a\ncommon base for creating concurrent safe fully validating nodes, Simplified\nPayment Verification (SPV) nodes, proxies, etc.\n\nA quick overview of the major features peer provides are as follows:\n\n - Provides a basic concurrent safe bitcoin peer for handling bitcoin\n   communications via the peer-to-peer protocol\n - Full duplex reading and writing of bitcoin protocol messages\n - Automatic handling of the initial handshake process including protocol\n   version negotiation\n - Asynchronous message queueing of outbound messages with optional channel for\n   notification when the message is actually sent\n - Flexible peer configuration\n   - Caller is responsible for creating outgoing connections and listening for\n     incoming connections so they have flexibility to establish connections as\n     they see fit (proxies, etc)\n   - User agent name and version\n   - Bitcoin network\n   - Service support signalling (full nodes, bloom filters, etc)\n   - Maximum supported protocol version\n   - Ability to register callbacks for handling bitcoin protocol messages\n - Inventory message batching and send trickling with known inventory detection\n   and avoidance\n - Automatic periodic keep-alive pinging and pong responses\n - Random nonce generation and self connection detection\n - Proper handling of bloom filter related commands when the caller does not\n   specify the related flag to signal support\n   - Disconnects the peer when the protocol version is high enough\n   - Does not invoke the related callbacks for older protocol versions\n - Snapshottable peer statistics such as the total number of bytes read and\n   written, the remote address, user agent, and negotiated protocol version\n - Helper functions pushing addresses, getblocks, getheaders, and reject\n   messages\n   - These could all be sent manually via the standard message output function,\n     but the helpers provide additional nice functionality such as duplicate\n     filtering and address randomization\n - Ability to wait for shutdown\/disconnect\n - Comprehensive test coverage\n\nPeer Configuration\n\nAll peer configuration is handled with the Config struct.  This allows the\ncaller to specify things such as the user agent name and version, the bitcoin\nnetwork to use, which services it supports, and callbacks to invoke when bitcoin\nmessages are received.  See the documentation for each field of the Config\nstruct for more details.\n\nInbound and Outbound Peers\n\nA peer can either be inbound or outbound.  The caller is responsible for\nestablishing the connection to remote peers and listening for incoming peers.\nThis provides high flexibility for things such as using proxies, acting as a\nproxy, creating bride peers, choosing whether to listen for inbound peers, etc.\n\nFor outgoing peers, the NewOutboundPeer function must be used to specify the\nconfiguration followed by invoking Connect with the net.Conn instance.  This\nstart all async I\/O goroutines and initiate the initial negotiation process.\nOnce that has been completed, the peer is fully functional.\n\nFor inbound peers, the NewInboundPeer function must be used to specify the\nconfiguration and net.Conn instance followed by invoking Start.  This will start\nall async I\/O goroutines and listen for the initial negotiation process.  Once\nthat has been completed, the peer is fully functional.\n\nCallbacks\n\nIn order to do anything useful with a peer, it is necessary to react to bitcoin\nmessages.  This is accomplished by creating an instance of the MessageListeners\nstruct with the callbacks to be invoke specified and setting the Listeners field\nof the Config struct specified when creating a peer to it.\n\nFor convenience, a callback hook for all of the currently supported bitcoin\nmessages is exposed which receives the peer instance and the concrete message\ntype.  In addition, a hook for OnRead is provided so even custom messages types\nfor which this package does not directly provide a hook, as long as they\nimplement the wire.Message interface, can be used.  Finally, the OnWrite hook\nis provided, which in conjunction with OnRead, can be used to track server-wide\nbyte counts.\n\nIt is often useful to use closures which encapsulate state when specifying the\ncallback handlers.  This provides a clean method for accessing that state when\ncallbacks are invoked.  TODO(davec): Provide example...\n\nQueuing Messages and Inventory\n\nThe QueueMessage function provides the fundamental means to send messages to the\nremote peer.  As the name implies, this employs a non-blocking queue.  A done\nchannel which will be notified when the message is actually sent can optionally\nbe specified.  There are certain message types which are better send using other\nfunctions which provide additional functionality.\n\nOf special interest are inventory messages.  Rather than manually sending MsgInv\nmessage via Queuemessage, the inventory vectors should be queued using the\nQueueInventory function.  It employs batching and trickling along with\nintelligent known remote peer inventory detection and avoidance through the use\nof a most-recently used algorithm.\n\nMessage Sending Helper Functions\n\nIn addition to the bare QueueMessage function previously described, the\nPushAddrMsg, PushGetBlocksMsg, PushGetHeadersMsg, and PushRejectMsg functions\nare provided as a convenience.  While it is of course possible to create and\nsend these message manually via QueueMessage, these helper functions provided\nadditional useful functionality that is typically desired.\n\nFor example, the PushAddrMsg function automatically limits the addresses to the\nmaximum number allowed by the message and randomizes the chosen addresses when\nthere are too many.  This allows the caller to simply provide a slice of known\naddresses, such as that returned by the addrmgr package, without having to worry\nabout the details.\n\nNext, the PushGetBlocksMsg and PushGetHeadersMsg functions will construct proper\nmessages using a block locator and ignore back to back duplicate requests.\n\nFinally, the PushRejectMsg function can be used to easily create and send an\nappropriate reject message based on the provided parameters as well as\noptionally provides a flag to cause it to block until the message is actually\nsent.\n\nPeer Statistics\n\nA snapshot of the current peer statistics can be obtained with the StatsSnapshot\nfunction.  This includes statistics such as the total number of bytes read and\nwritten, the remote address, user agent, and negotiated protocol version.\n\nLogging\n\nThis package provides extensive logging capabilities through the UseLogger\nfunction which allows a btclog.Logger to be specified.  For example, logging at\nthe debug level provides summaries of every message sent and received, and\nlogging at the trace level provides full dumps of parsed messages as well as the\nraw message bytes using a format similar to hexdump -C.\n\nBitcoin Improvement Proposals\n\nThis package supported all BIPS support by the\n[wire](https:\/\/godoc.org\/github.com\/btcsuite\/btcd\/wire#hdr-Bitcoin_Improvement_Proposals)\npackage.\n*\/\npackage peer\n<commit_msg>peer: Correct a few typos in documentation.<commit_after>\/\/ Copyright (c) 2015 The btcsuite developers\n\/\/ Use of this source code is governed by an ISC\n\/\/ license that can be found in the LICENSE file.\n\n\/*\nPackage peer provides a common base for creating and managing Bitcoin network\npeers.\n\nOverview\n\nThis package builds upon the wire package, which provides the fundamental\nprimitives necessary to speak the bitcoin wire protocol, in order to simplify\nthe process of creating fully functional peers.

While it is of course possible to create and\nsend these message manually via QueueMessage, these helper functions provided\nadditional useful functionality that is typically desired.\n\nFor example, the PushAddrMsg function automatically limits the addresses to the\nmaximum number allowed by the message and randomizes the chosen addresses when\nthere are too many.  This allows the caller to simply provide a slice of known\naddresses, such as that returned by the addrmgr package, without having to worry\nabout the details.\n\nNext, the PushGetBlocksMsg and PushGetHeadersMsg functions will construct proper\nmessages using a block locator and ignore back to back duplicate requests.\n\nFinally, the PushRejectMsg function can be used to easily create and send an\nappropriate reject message based on the provided parameters as well as\noptionally provides a flag to cause it to block until the message is actually\nsent.\n\nPeer Statistics\n\nA snapshot of the current peer statistics can be obtained with the StatsSnapshot\nfunction.  This includes statistics such as the total number of bytes read and\nwritten, the remote address, user agent, and negotiated protocol version.\n\nLogging\n\nThis package provides extensive logging capabilities through the UseLogger\nfunction which allows a btclog.Logger to be specified.  For example, logging at\nthe debug level provides summaries of every message sent and received, and\nlogging at the trace level provides full dumps of parsed messages as well as the\nraw message bytes using a format similar to hexdump -C.\n\nBitcoin Improvement Proposals\n\nThis package supports all BIPS supported by the wire packge.\n(https:\/\/godoc.org\/github.com\/btcsuite\/btcd\/wire#hdr-Bitcoin_Improvement_Proposals)\n*\/\npackage peer\n<|endoftext|>"}

First, if \"REMARK 465\" is\n\/\/ present in the PDB file, it will be used to determine the positions of the\n\/\/ holes in the sequence (i.e., residues in SEQRES without an ATOM record).\n\/\/ This method is generally reliable, since REMARK 465 lists all residues\n\/\/ in SEQRES that don't have an ATOM record. This will fail if there are any\n\/\/ unreported missing residues.\n\/\/\n\/\/ If \"REMARK 465\" is absent, then we have to rely on the order of ATOM records\n\/\/ to correspond to a residue index in the SEQRES sequence. This will fail\n\/\/ with an error if there are any unreported missing residues.\n\/\/\n\/\/ Generally, false positives are limited by returning errors if corruption\n\/\/ is detected. However, false positives can be returned in pathological cases\n\/\/ (like long strings of low complexity regions or UNKNOWN amino acids), but\n\/\/ they are rare.

This wrapper interface\npanics when the input arguments are invalid as per the standard, for example\nif a vector increment is zero. Please note that the treatment of NaN values\nis not specified, and differs among the BLAS implementations.\ngithub.com\/gonum\/blas\/blas64 provides helpful wrapper functions to the BLAS\ninterface. The rest of this text describes the layout of the data for the input types.\n\nPlease note that in the function documentation, x[i] refers to the i^th element\nof the vector, which will be different from the i^th element of the slice if\nincX != 1.\n\nVector arguments are effectively strided slices. They have two input arguments,\na number of elements, n, and an increment, incX. The increment specifies the\ndistance between elements of the vector. The actual Go slice may be longer\nthan necessary.\nThe increment may be positive or negative, except in functions with only\na single vector argument where the increment may only be positive. If the increment\nis negative, s[0] is the last element in the slice. Note that this is not the same\nas counting backward from the end of the slice, as len(s) may be longer than\nnecessary. So, for example, if n = 5 and incX = 3, the elements of s are\n\t[0 * * 1 * * 2 * * 3 * * 4 * * * ...]\nwhere ∗ elements are never accessed. If incX = -3, the same elements are\naccessed, just in reverse order (4, 3, 2, 1, 0).\n\nDense matrices are specified by a number of rows, a number of columns, and a stride.\nThe stride specifies the number of entries in the slice between the first element\nof successive rows.

This wrapper interface\npanics when the input arguments are invalid as per the standard, for example\nif a vector increment is zero. Please note that the treatment of NaN values\nis not specified, and differs among the BLAS implementations.\ngithub.com\/gonum\/blas\/blas64 provides helpful wrapper functions to the BLAS\ninterface. The rest of this text describes the layout of the data for the input types.\n\nPlease note that in the function documentation, x[i] refers to the i^th element\nof the vector, which will be different from the i^th element of the slice if\nincX != 1.\n\nVector arguments are effectively strided slices. They have two input arguments,\na number of elements, n, and an increment, incX. The increment specifies the\ndistance between elements of the vector. The actual Go slice may be longer\nthan necessary.\nThe increment may be positive or negative, except in functions with only\na single vector argument where the increment may only be positive. If the increment\nis negative, s[0] is the last element in the slice. Note that this is not the same\nas counting backward from the end of the slice, as len(s) may be longer than\nnecessary. So, for example, if n = 5 and incX = 3, the elements of s are\n\t[0 * * 1 * * 2 * * 3 * * 4 * * * ...]\nwhere ∗ elements are never accessed. If incX = -3, the same elements are\naccessed, just in reverse order (4, 3, 2, 1, 0).\n\nDense matrices are specified by a number of rows, a number of columns, and a stride.\nThe stride specifies the number of entries in the slice between the first element\nof successive rows. The stride must be at least as large as the number of columns\nbut may be longer.\n\t[a00 ... a0n a0* ... a1stride-1 a21 ... amn am* ... amstride-1]\nThus, dense[i*ld + j] refers to the {i, j}th element of the matrix.\n\nSymmetric and triangular matrices (non-packed) are stored identically to Dense,\nexcept that only elements in one triangle of the matrix are accessed.\n\nPacked symmetric and packed triangular matrices are laid out with the entries\ncondensed such that all of the unreferenced elements are removed. So, the upper triangular\nmatrix\n  [\n    1  2  3\n    0  4  5\n    0  0  6\n  ]\nand the lower-triangular matrix\n  [\n    1  0  0\n    2  3  0\n    4  5  6\n  ]\nwill both be compacted as [1 2 3 4 5 6]. The (i, j) element of the original\ndense matrix can be found at element i*n - (i-1)*i\/2 + j for upper triangular,\nand at element i * (i+1) \/2 + j for lower triangular.\n\nBanded matrices are laid out in a compact format, constructed by removing the\nzeros in the rows and aligning the diagonals.

The BLAS standard is silent on a number of behaviours, including\nbut not limited to how NaN values are treated. For this reason the result of\ncomputations performed by the cgo BLAS package may disagree with the results\nproduced by native BLAS package. The cgo package is tested agains OpenBLAS; use\nof other backing BLAS C libraries may cause result in test failure because of\nthis.\n*\/\npackage cgo\n<|endoftext|>"}

It is a weak substitute for upspinfs.\n\nTo start, create a local directory whose path ends in a string that looks like\nan existing upspin directory, such as ~\/u\/alice@example.com. Cd there and execute\nupsync.  Make local edits to the downloaded files or create new files, and then\nupsync to upload your changes to the Upspin master. To discard your local changes,\njust remove the edited local files and upsync. (Executing both local rm and\nupspin rm are required to remove content permanently.)\n\nUpsync prints which files it is uploading or downloading and declines to download\nfiles larger than 50MB. It promises never to write outside the starting directory\nand subdirectories and, as an initial way to enforce that, declines all symlinks.\n\nThere are no clever merge heuristics;  copying back and forth proceeds by a trivial\n\"newest wins\" rule.  This requires some discipline in remembering to upsync after\neach editing session and is better suited to single person rather than joint\nediting. Don't let your computer clocks drift.\n\nWith better FUSE support on Windows and OpenBSD it will be possible to switch\nto the much preferable upspinfs.

It is a weak substitute for upspinfs.\n\nTo start, create a local directory whose path ends in a string that looks like\nan existing upspin directory, such as ~\/u\/alice@example.com. Cd there and execute\nupsync.  Make local edits to the downloaded files or create new files, and then\nupsync to upload your changes to the Upspin master. To discard your local changes,\njust remove the edited local files and upsync. (Executing both local rm and\nupspin rm are required to remove content permanently.)\n\nUpsync prints which files it is uploading or downloading and declines to download\nfiles larger than 50MB. It promises never to write outside the starting directory\nand subdirectories and, as an initial way to enforce that, declines all symlinks.\n\nThere are no clever merge heuristics;  copying back and forth proceeds by a trivial\n\"newest wins\" rule.  This requires some discipline in remembering to upsync after\neach editing session and is better suited to single person rather than joint\nediting.

URL to which the push is being done\n\/\/\n\/\/ The hook receives commit information on stdin in the form:\n\/\/   <local ref> <local sha1> <remote ref> <remote sha1>\n\/\/\n\/\/ In the typical case, pushCommand will get a list of git objects being pushed\n\/\/ by using the following:\n\/\/    git rev-list --objects <local sha1> ^<remote sha1>\n\/\/\n\/\/ If any of those git objects are associated with hawser objects, those hawser\n\/\/ objects will be pushed to the hawser endpoint.\n\/\/\n\/\/ In the case of pushing a new branch, the list of git objects will be all of\n\/\/ the git objects in this branch.\n\/\/\n\/\/ In the case of deleting a branch, no attempts to push hawser objects will be\n\/\/ made.\n\/\/\n\/\/ When pushing hawser objects, the client will first perform an OPTIONS command\n\/\/ which will determine not only whether or not the client is authorized, but also\n\/\/ whether or not that hawser endpoint already has the hawser object. If it\n\/\/ does, the object will not be pushed.\n\/\/\n\/\/ The other mode of operation is the dry run mode. In this mode, the repo\n\/\/ and refspec are passed on the command line. pushCommand will calculate the\n\/\/ git objects that would be pushed in a similar manner as above and will print\n\/\/ out each file name.\nfunc pushCommand(cmd *cobra.Command, args []string) {\n\tvar left, right string\n\n\tif len(args) == 0 {\n\t\tPrint(\"The git hawser pre-push hook is out of date.

They are pure values (no hidden data).\n\nThe notation also tries to be as close to GLSL as possible: literals use the\nsame component order, function names are similar, and component access for\nmatrices is identical: m[2][3] means the same thing in Go than in GLSL.\n\nTransformation Matrices\n\nAs is usual in GLSL, to transform a vector use left-multiplication by a\nmatrix:\n\tT := Translation4(10, 15, 2)\n\tv := Vec4{1, 2, 3}\n\tvTrans := T.Transform(v)\n\nWhen writing literals, remember to use the transpose of the mathematical\nnotation. In other words the following mathematical notation:\n\t⎡ a11  a12  a13 ⎤\n\t⎢ a21  a22  a23 ⎥\n\t⎣ a31  a32  a33 ⎦\nTranslates to:\n    m := Mat3{\n\t\t{a11, a21, a31},\n\t\t{a12, a22, a32},\n\t\t{a13, a23, a33},\n    }\n\nNote that the same inversion happens with indices: the last component\nof the first column is written a31 in math but accessed with m[0][2] in Go\n(and GLSL).\n\nFinally, although all methods returns their result by value, they take their\nreceiver and parameters by reference, for efficiency. They are never modified.\n\nNote: Some describes this convention as \"column-major\". This can be confusing,\nbecause it depends on the meaning assigned to the indices of 2D arrays. E.g.\nWikipedia describes C as row-major, but in doing so assumes that arrays are\naccessed with a[row][col]. OpenGL, defined as column-major, uses (inGLSL) the\nexact same data structure and notation than C, but assumes arrays are accessed\nwith a[col][row]. What really matters is the underlying memory layout, and the\norder of matrix-vector multiplication. Yet another way to describe the\nsituation is to say that vectors are treated as column-vectors.\n*\/\npackage geom\n<|endoftext|>"}

When Handler is not nil, it is\n\/\/ the responsibility of the handler to eventually call ProcessMsg so\n\/\/ that the messages produce the expected results.\n\/\/\n\/\/ Typical use of handlers can be:\n\/\/\n\/\/     - to implement logging of requests\/responses\n\/\/     - to recover in case of panics\n\/\/     - to implement authentication for some requests\n\/\/     - to implement authorization checks for some requests\n\/\/     - etc.\n\/\/\n\/\/ If a handler detects that the message cannot be executed as requested,\n\/\/ e.g. because the caller is not authenticated or doesn't have access\n\/\/ to the requested RPC URI, ProcessMsg must not be called.

All rights reserved.\n\/\/ Use of this source code is governed by a BSD style license\n\/\/ that can be found in the LICENSE file.\n\n\/*\nCompatibility\n\nThe gohg client library is created with Go1 (v1.0.3). It is tested against\nMercurial 2.5.2, both on Windows 7 and Ubuntu 12.04.\n\nCurrently there is no mechanism to handle differences in possibilities between\ndifferent Mercurial versions. The errors returned by Mercurial are your only\nhelp here.\n\nDependencies\n\nOnly Go and it's standard library. Though I'm using gocov for checking test\ncoverage (see https:\/\/github.com\/axw\/gocov).\n\nInstallation\n\nAt the commandline type:\n  go get [-u] bitbucket.org\/gohg\/gohg\n  go test -v bitbucket.org\/gohg\/gohg\n\nImport the package\n\nStart with importing the gohg package:\n  import . \"bitbucket.org\/gohg\/gohg\"\n\nConnecting the Mercurial Command Server\n\nAll interaction with the Mercurial Command Server (Hg CS from now on) happens\nthrough the HgClient type, of which you have to create an instance:\n\n  hc :=  NewHgClient()\n\nThen you can connect the Hg CS:\n\n  err := hc.Connect(\"hg\", \"~\/myrepo\", nil)\n   4                 1        2        3\n\n1. The Hg executable:\n\nThe first parameter is the Mercurial command to use (which 'hg'). You can leave\nit blanc to let the gohg tool use the default Mercurial command on the system.\nHaving a parameter for the Hg command allows for using a different Hg version,\nfor testing purposes for instance.\n\n2. The repository path:\n\nThe second parameter is the path to the repository you want to work on. You can\nleave it blanc to have gohg use the repository it can find for the current path\n(searching upward in the folder tree eventually).\n\n3. The config for the session:\n\nThe third parameter allows to provide extra configuration for the session.\nThough this is currently not implemented yet.\n\n4. The returnvalue:\n\nThe HgClient.Connect() method eventually returns an error, so you can check if\nthe connection succeeded, and if it is safe to go on or not.\n\nOnce the work is done, you can disconnect the Hg CS. We advise to use a typical\nGo idiom for this:\n\n  err := hc.Connect(\"hg\", \"~\/myrepo\", nil)\n  if err != nil {\n      log.Fatal(err)\n  }\n  defer hc.Disconnect()\n  \/\/ do the real work here\n\nConfig\n\nThe gohg tool sets some environment variables for the Hg CS session, to ensure\nit's good working:\n  \/\/ ensure Hg works in english\n  HGPLAIN=True\n  \/\/ Use only the .hg\/hgrc from the repo itself.\n  HGRCPATH=''\n  HGENCODING=UTF-8\n\nCommands\n\nOnce we have a connection to a Hg CS we can do some work with the repository.\nThis is done with commands, and gohg offers 3 ways for issuing them.\n\n1.

It is a struct that you can\ninstantiate for any new command, and for which you can set elements Name,\nOptions and Params (see the api docs hereafter for more details). It allows for\nbuilding the command step by step, and also to query the exact command that will\nbe sent to the Hg CS.\n\nA pro of this method is that it allows you to obtain the exact command string\nthat will be passed to Mercurial, as you would type it on the commandline. This\ncould be handy for logging, or for showing feedback to the user in a GUI program.\n\nAn example (also see examples\/example2.go):\n\n  opts := make([]Option, 2)\n  var lim Limit = 2\n  opts[0] = lim\n  var verb Verbose = true\n  opts[1] = verb\n  hc.SetOptions(opts)\n  hc, _ := NewHgCmd(\"log\", opts, nil, new(logOpts))\n  cmdline, _ := hc.CmdLine(hgcl)\n  fmt.Printf(\"%s\\n\", cmdline) \/\/ output: log --limit 2 -v\n  hc.Exec(hgcl)\n\nAs you can see, this way requires some more coding.\n\nThe api docs will also show you the HgCmd type has a convenient constructor for\neach command, allowing for easy and correct initialization of the new command\ntype.\n\nCommands - ExecCmd\n\nThe HgClient type has an extra method ExecCmd(), allowing you to pass a fully\ncustom build command to Hg. It accepts a string slice that is supposed to\ncontain the complete command, as you would type it at the command line.\n\nIt could be a convenient way for issuing commands that are not yet implemented\nin gohg, or to make use of extensions to Hg (for which gohg offers no support).\n\nAn example:\n\n  \/\/ hgcl is a HgClient instance that has a connection to the Hg CS\n  hgcmd := []string{\"log\", \"--limit\", \"2\"}\n  result, err := hgcl.ExecCmd(hgcmd)\n\nOptions and Parameters\n\nJust like on the commandline, options come before parameters.\n\n  opts := []Option{Verbose(true), Limit(2)}\n  params := []string{\"mytool.go\"}\n  log, err := hc.Log(opts, params)\n\nOptions to commands use the same name as the long form of the Mercurial option\nthey represent, but start with a capital letter (as do all exported symbols in\nGo). An options value can be of type bool, int or string. You just pass the\nvalue as the parameter to the option (= type conversion of the value to the\noption type). You can pass any number of options, as the elements of a slice.\nOptions can occur more than once if appropriate (see the ones marked with '[+]'\nin the Mercurial help).\n\n  log, err := hc.Log([]Option{Verbose(true)}, nil)\n  log, err := hc.Log([]Option{Limit(2)}, nil)\n  log, err := hc.Log([]Option{User(\"John Doe\"), User(\"me\")}, nil)\n\nParameters are used to provide any arguments for a command that are not options.\nThey are passed in as a string or a string slice, depending on the command.\nThese parameters typically contain revisions, paths or filenames and so.\n\n  log, err := hc.Log(nil, []string{\"myfile\"})\n  heads, err := hc.Heads(nil, []string{\"foobranch\"})\n\nThe gohg tool only checks if the options the caller gives are valid for that\ncommand. It does not check if the values are valid for the combination of that\ncommand and that option, as that is done by Mercurial. No need to implement that\nagain. If an option is not valid for a command, it is silently ignored, so it is\nnot passed to the Hg CS.\n\nSome options are not implemented, as they seemed not relevant for use with this\ntool (for instance: the global --color option, or the --print0 option for\nstatus).\n\nError handling\n\nThe gohg tool only returns errors, with an as clear as possible message, and\nnever uses log.Fatal() nor panics, even if those may seem appropriate. It leaves\nit up to the caller to do that eventually.

It is tested against\nMercurial 2.5.2, both on Windows 7 and Ubuntu 12.04.\n\nCurrently there is no mechanism to handle differences in possibilities between\ndifferent Mercurial versions. The errors returned by Mercurial are your only\nhelp here.\n\nDependencies\n\nOnly Go and it's standard library. Though I'm using gocov for checking test\ncoverage (see https:\/\/github.com\/axw\/gocov).\n\nInstallation\n\nAt the commandline type:\n  go get [-u] bitbucket.org\/gohg\/gohg\n  go test -v bitbucket.org\/gohg\/gohg\n\nImport the package\n\nStart with importing the gohg package:\n  import . \"bitbucket.org\/gohg\/gohg\"\n\nConnecting the Mercurial Command Server\n\nAll interaction with the Mercurial Command Server (Hg CS from now on) happens\nthrough the HgClient type, of which you have to create an instance:\n\n  hc :=  NewHgClient()\n\nThen you can connect the Hg CS:\n\n  err := hc.Connect(\"hg\", \"~\/myrepo\", nil)\n   4                 1        2        3\n\n1. The Hg executable:\n\nThe first parameter is the Mercurial command to use (which 'hg'). You can leave\nit blanc to let the gohg tool use the default Mercurial command on the system.\nHaving a parameter for the Hg command allows for using a different Hg version,\nfor testing purposes for instance.\n\n2. The repository path:\n\nThe second parameter is the path to the repository you want to work on. You can\nleave it blanc to have gohg use the repository it can find for the current path\n(searching upward in the folder tree eventually).\n\n3. The config for the session:\n\nThe third parameter allows to provide extra configuration for the session.\nThough this is currently not implemented yet.\n\n4. The returnvalue:\n\nThe HgClient.Connect() method eventually returns an error, so you can check if\nthe connection succeeded, and if it is safe to go on or not.\n\nOnce the work is done, you can disconnect the Hg CS. We advise to use a typical\nGo idiom for this:\n\n  err := hc.Connect(\"hg\", \"~\/myrepo\", nil)\n  if err != nil {\n      log.Fatal(err)\n  }\n  defer hc.Disconnect()\n  \/\/ do the real work here\n\nConfig\n\nThe gohg tool sets some environment variables for the Hg CS session, to ensure\nit's good working:\n  \/\/ ensure Hg works in english\n  HGPLAIN=True\n  \/\/ Use only the .hg\/hgrc from the repo itself.\n  HGRCPATH=''\n  HGENCODING=UTF-8\n\nCommands\n\nOnce we have a connection to a Hg CS we can do some work with the repository.\nThis is done with commands, and gohg offers 3 ways for issuing them.\n\n1. The command methods of the HgClient type.\n\n2. The HgCmd type.\n\n3.

{"text":"<commit_before>\/*\n\nboardgame is a package that makes it possible to build boardgames with minimial fuss.\n\nboardgame\/server implements a progressive web app based on your game with just\na few lines of configuration.\n\nGames\n\nGames are the funamdental object. They represent a specific game with a\ncertain number of players and a versioned history of States. Once created,\ngames can only be modified by Moves.\n\nEach game is associated with one GameManager. The GameManager manages state\nthat is shared across multiple games (like components, moves, delegates, etc)\nand interacts with the storage layer.\n\nThe majority of a game's state is stored as a State--a JSON-able object that\nrepresents the entirety of the semantic state for the game, in a manner\nparticular to this type of game. Your State's GameState and PlayerState\nobjects will primarily be composed of bools, ints, and Stacks (see the\nComponents section, below).\n\nEach game has a Version() that monotonically increases as Moves are\nsuccessfully applied to the game to modify it. Each version has precisely one\nState associated with it. Once a state is created, it can never be modified.\n\nGames have a Modifiable property. When a game is first created it is\nModifiable, but most other games are not modifiable--when they are created\nthey are set to a snapshot of what the storage layer has for that game. This\nreflects that multiple Game objects might represent the same notional game as\nfar as the storage layer is concerned. As long as you use the same manager,\nonly one Modifiable version of a given notional Game will ever be in\nexistence.\n\nNewGames are empty, and must be SetUp() before moves can be applied to them.\nOnly Modifiable games may actually have a move applied to them. More in the\nnext section.\n\nMoves\n\nMoves are the only way to modify a game's state. A given type of game has a\ncollection of Moves that may be used. The GameManager maintains a set of all\nof the different types of moves that may be used in this game type.\n\nMoves can be serialized as JSON and contain a set of properties that together\ndefine all of the information necessary to fully describe the Move.\n\nMoves have a Legal method that is given a State object and returns an error if\nthe Move is not legal to make at the given game state.\n\nMoves have an Apply method that is given a new state object to modify in\naccordance with the game's semantics.\n\nGames have a ProposeMove method that takes a Move object and queues it up to\nbe Applied to the Game. If the given Game is not modifiable, the move will be\ndispatched, via the GameManager, to a Game object for this notional Game that\nis.\n\nMoves that are proposed are considered in order. Their Legal method is called\nwith the CurrentState of the Game (it may have changed if there were other\nMoves ahead of this move in the queue). If the move is still legal, it will be\napplied. The game's version number will increment, and a new State will be\naddded to the history that reflects the output of that Move's Apply method.\n\nThere are two types of Moves: PlayerMoves, and FixUpMoves. PlayerMoves are\nmoves that can be proposed by Players. FixUp moves are moves that are never\nlegal to be applied by players. These FixUp moves are \"meta\" moves that help\nkeep the game in a consistent, playable state. For example, a typical FixUp\nMove is AdvanceCurrentPlayer, which notes that the current player has no more\nvalid actions left and then advances so it is the next player's turn.\n\nAfter each Move is Apply'd, the Game's Delegate (see below) is given an\nopportunity to examine the new State of the game and decide if a FixUp move\nshould be applied.\n\nAfter each move, and when there are no more FixUp moves to apply, the Game\nchecks to see if the game is now over by asking its Delegate (see below). If\nso, the game is marked as Finished, and the winners are noted. At that point\nno more moves may be applied.\n\nGame Delegates\n\nEach GameManager has a reference to a GameDelegate that is specific to this\ngame type. The GameDelegate is where you can configure precise behaviors that\nhappen at key points in the lifecycle of your particular game type.\n\nFor example, Delegates are consulted in the following points:\n\n1) After every Move is applied, to decide if a FixUp move should not be\napplied before the next PlayerMove in the queue is applied. For example, you\nmight have a ShuffleDiscardStackToDrawStack that is Legal whenever the\nDrawStack is empty.\n\n2) To initialize the State. When your game is first created, your Delegate\nwill provide the first concrete State object. Future state objects will be\ncreated by Copying and modifying this state object.\n\n3) Deserializing State objects from storage. Your storage objects will have\nbeen serialized as JSON and must be reinflated into concrete types.\n\n4) CheckGameFinished(), called after every move, checks the game's\nCurrentState to see if the game is now finished, and if so, who won.\n\nIn some cases, your delegate doesn't need to do much special. For example,\nDelegate.ProposeFixUp() is often the same for many games: iterate through each\nFixUpMove that has been configured on the manager, and return the first one\nthat is Legal(). For those reasons, this package defines a DefaultGameDelegate\nthat is designed to be anonymously embedded into your own struct, so you only\nneed to modify the behavior of the methods whose behavior is actually special\nto your game.\n\nComponents\n\nYour game has a set of Components, which is every object that could be moved\naround in the game. In practice, it includes dice, cards, meeples, resource\ntokens, and anything else that a real-world board game would enumerate in its\nComponents section for players trying to verify that they still had all of the\nnecessary pieces. Components have a set of immutable properties. Different\ntypes of components in your game might have different types of properties.\n\nThere is one global set of Components that are used in each type of game. This\nset is called a Component Chest. After it is created, its shape is frozen and\nassociated with your GameManager.\n\nThe Chest consists of 0 to n Decks. A Deck is a collection of components, all\nof the same basic type. For example, in Ticket To Ride your Chest might have a\nDeck of Contract Cards, and a Deck of train cards. The terminology for Decks\nmakes the most sense for cards, but it applies for any components. For\nexample, if your game included multiple dice, you might have them in a Deck\ncalled \"Dice\".\n\nYour State object will contain a collection of Stacks. Stacks are mutable\nordered collections of Components of a specific type. For example, you might\nhave a Stack for the Draw pile, a Stack for Discard pile, and a stack\nrepresenting each player's hand. Every component in the Chest must live in\nprecisely one Stack at every State in your game. During Game set-up, your\ndelegate's DistributeComponentToStarterStack will be called for each component\nin the chest in turn, which helps you conform to this important invariant from\nthe very beginning, and then make sure to maintain it in each Move's Apply\nmethod.\n\nImplementing Your Own Game\n\nWhen you are implementing your own game, at a high level you must do the\nfollowing things:\n\n1) Define a State implementation that fully captures all of the semantic state\nof the game at all times. In practice this will likely include state that is\ncentral to the game, as well as state specific to each user. It often includes\nmore things than you might first think. For example, your state should include\nhow many of each type of action the current player can still do in their turn,\nso that your game can decide when to advance to the next player. Ensure that\neach State object can be serialized by json.Marhsal().\n\n2) Define the complete set of Components that exist in your game. Every item\nthat could be manipulated or moved, including cards, meeples, resource tokens,\ndice, and much more, should be enumerated in your Component Chest.\n\n3) Define a GameDelegate that overrides various game level logic at key points\nin a Game's lifecycle. For example, the delegate is consulted to provide a\nstarting state for a new game, to decide if a game is now finished, whether\nany fixup moves should be applied, and much more. A substantial portion of the\nlogical \"meat\" of your implementation will be here.\n\n4) Define a set of Moves that fully define all of the possible modifcations\nthat could ever occur in your game, both for Players and FixUp moves. Each\nMove needs a Legal() and Apply() method, and should be fully serialized by\njson.Marshal(). This is where the majority of the logical \"meat\" of your game\ndefinition will live.\n\n5) Often the end result of your game will be a Progressive Web App. You'll\nneed to do a few more things, as described in the boardgame\/server package, to\ncomplete the web app.\n\nReflection and Properties\n\nThe aim of the boardgame package is to make it as easy as possible for you to\nimplement your own boardgames, focusing only on the central semantic logic of\nthe game. The package tries to hit a sweet spot between concrete types whose\nbehavior is modified by delegates, and interfaces that you must implement.\n\nStates, Moves, and Components, in particular, will have a set of properties\nthat is very specific to your particular game and taht particular object type.\nThe package itself tries to rely on reflection only rarely, and only when\ninstructed to. In practice, inside of your Move.Apply, Move.Legal, and\nDelegate methods, you will often immediately cast the provided generic Move,\nState, or Component to the underlying type you know it is.\n\nEvery so often the package has to interact with objects whose shape it does\nnot know. It relies on the PropertyReader and PropertyReadSetter interfaces to\ndo this manipulation. Implementing these methods can be a pain, which is why\nthis package provides a set of implementation methods that rely on reflection\nto satisfy these interfaces.\n\n*\/\npackage boardgame\n<commit_msg>Long package doc on ACLs and Sanitization.

Their Legal method is called\nwith the CurrentState of the Game (it may have changed if there were other\nMoves ahead of this move in the queue). If the move is still legal, it will be\napplied. The game's version number will increment, and a new State will be\naddded to the history that reflects the output of that Move's Apply method.\n\nThere are two types of Moves: PlayerMoves, and FixUpMoves. PlayerMoves are\nmoves that can be proposed by Players. FixUp moves are moves that are never\nlegal to be applied by players. These FixUp moves are \"meta\" moves that help\nkeep the game in a consistent, playable state. For example, a typical FixUp\nMove is AdvanceCurrentPlayer, which notes that the current player has no more\nvalid actions left and then advances so it is the next player's turn.\n\nAfter each Move is Apply'd, the Game's Delegate (see below) is given an\nopportunity to examine the new State of the game and decide if a FixUp move\nshould be applied.\n\nAfter each move, and when there are no more FixUp moves to apply, the Game\nchecks to see if the game is now over by asking its Delegate (see below). If\nso, the game is marked as Finished, and the winners are noted. At that point\nno more moves may be applied.\n\nGame Delegates\n\nEach GameManager has a reference to a GameDelegate that is specific to this\ngame type. The GameDelegate is where you can configure precise behaviors that\nhappen at key points in the lifecycle of your particular game type.\n\nFor example, Delegates are consulted in the following points:\n\n1) After every Move is applied, to decide if a FixUp move should not be\napplied before the next PlayerMove in the queue is applied. For example, you\nmight have a ShuffleDiscardStackToDrawStack that is Legal whenever the\nDrawStack is empty.\n\n2) To initialize the State. When your game is first created, your Delegate\nwill provide the first concrete State object. Future state objects will be\ncreated by Copying and modifying this state object.\n\n3) Deserializing State objects from storage. Your storage objects will have\nbeen serialized as JSON and must be reinflated into concrete types.\n\n4) CheckGameFinished(), called after every move, checks the game's\nCurrentState to see if the game is now finished, and if so, who won.\n\nIn some cases, your delegate doesn't need to do much special. For example,\nDelegate.ProposeFixUp() is often the same for many games: iterate through each\nFixUpMove that has been configured on the manager, and return the first one\nthat is Legal(). For those reasons, this package defines a DefaultGameDelegate\nthat is designed to be anonymously embedded into your own struct, so you only\nneed to modify the behavior of the methods whose behavior is actually special\nto your game.\n\nComponents\n\nYour game has a set of Components, which is every object that could be moved\naround in the game. In practice, it includes dice, cards, meeples, resource\ntokens, and anything else that a real-world board game would enumerate in its\nComponents section for players trying to verify that they still had all of the\nnecessary pieces. Components have a set of immutable properties. Different\ntypes of components in your game might have different types of properties.\n\nThere is one global set of Components that are used in each type of game. This\nset is called a Component Chest. After it is created, its shape is frozen and\nassociated with your GameManager.\n\nThe Chest consists of 0 to n Decks. A Deck is a collection of components, all\nof the same basic type. For example, in Ticket To Ride your Chest might have a\nDeck of Contract Cards, and a Deck of train cards. The terminology for Decks\nmakes the most sense for cards, but it applies for any components. For\nexample, if your game included multiple dice, you might have them in a Deck\ncalled \"Dice\".\n\nYour State object will contain a collection of Stacks. Stacks are mutable\nordered collections of Components of a specific type. For example, you might\nhave a Stack for the Draw pile, a Stack for Discard pile, and a stack\nrepresenting each player's hand. Every component in the Chest must live in\nprecisely one Stack at every State in your game. During Game set-up, your\ndelegate's DistributeComponentToStarterStack will be called for each component\nin the chest in turn, which helps you conform to this important invariant from\nthe very beginning, and then make sure to maintain it in each Move's Apply\nmethod.\n\nSanitization\n\nThe server canonically knows all state in a game. However, there are certain\nbits of state that should not be known by specific players. For example, in\npoker,the other players should not know the two hidden cards in your hand.\n\nboardgame handles this with a notion of sanitization. When preparing a state\nobject to be sent to a client, it is possible to get a sanitized version of\nthe state with GameManager.SanitizedStateForPlayer(index). This will sanitize\ncertain fields according to a policy that your Delegate defines in\nStateSanitizationPolicy. The result is a copy of the input state, with the\nvarious fields obscured, and which will have Sanitized() return true. All of\nthe fields will always have the same \"shape\" as before (e.g. GrowableStacks\nwill not be reduced to an int), but will have key properties changed so that\nless information can be recovered.\n\nThe policy for a game will never change during the course of the game; it is\ntied to which player the state is being prepared for, which key we are\nconsidering, and which groups the various players are in. The same policy will\nbe applied to each PlayerState in the State; use Groups to change the behavior.\n\nboardgame has no notion of who is who; it will generate a SanitizedState for\nwhomever you request. Other packages, like Server, keep track of which person\nis which via mechanisms like cookies.\n\nThere are a number of policies that can be applied to each key, of type\nPolicy. PolicyVisible is the default; if there is no effective policy in\nplace, it defaults to PolicyVisible. It leaves the property unchanged.\nPolicyHidden is the most restrictive; it sets the property to its zero value.\nFor basic types (e.g. int, string, bool), these are the only two policies. Any\nPolicy other than PolicyVisible behaves like PolicyHidden.\n\nGroups (e.g. SizedStacks and GrowableStacks) have a few extra policies.\nPolicyLen will obscure the group so that the number of items is clear, but all\nelements will be replaced by the Deck's GenericComponent. PolicyNonEmpty is\nsimilar to PolicyLen, but if the real Stack has 1 or more components, the\noutput result will have a single GenericComponent. This allows you to observe\nwhether the stack was empty or not, but not anything about how many components\nit had. PolicyOrder replaces each Component with a stable but obscured\nShadowComponent, so that observes can keep track of the lenght, and when\ncomponents swithc orders in the stack, but not what the underlying components\nare.\n\nTo compute the effective policy for a given property, we have to consider the\nGroups. Conceptually there are a number of groups, which define which players\nare in or out of each one. In the future there will be a way to define group\nmembership that can be modified just like any other part of the state. At this\npoint there are three special groups.  Every player is a member of GroupAll.\nGroupSelf is the group that only the player who the state is being prepared\nfor is in. GroupOther contains all players who the state is not being prepared\nfor.\n\nPolicies contain GroupPolicies for each key in Game and State. GroupPolicies\nare a map of Group ID to the effective policy. When preparing a sanitized\nstate for a given property, we to through each group\/policy pair in the\nGroupPolicy. We collect each policy where the player that the state is being\nprepared for is in. Then the effective policy is the *least* restrictive\npolicy that applies. In practice this means that policies like\nGroupAll:PolicyLen, GroupSelf:PolicyVisible make sense to do.\n\nImplementing Your Own Game\n\nWhen you are implementing your own game, at a high level you must do the\nfollowing things:\n\n1) Define a State implementation that fully captures all of the semantic state\nof the game at all times. In practice this will likely include state that is\ncentral to the game, as well as state specific to each user. It often includes\nmore things than you might first think. For example, your state should include\nhow many of each type of action the current player can still do in their turn,\nso that your game can decide when to advance to the next player. Ensure that\neach State object can be serialized by json.Marhsal().\n\n2) Define the complete set of Components that exist in your game. Every item\nthat could be manipulated or moved, including cards, meeples, resource tokens,\ndice, and much more, should be enumerated in your Component Chest.\n\n3) Define a GameDelegate that overrides various game level logic at key points\nin a Game's lifecycle. For example, the delegate is consulted to provide a\nstarting state for a new game, to decide if a game is now finished, whether\nany fixup moves should be applied, and much more. A substantial portion of the\nlogical \"meat\" of your implementation will be here.\n\n4) Define a set of Moves that fully define all of the possible modifcations\nthat could ever occur in your game, both for Players and FixUp moves. Each\nMove needs a Legal() and Apply() method, and should be fully serialized by\njson.Marshal(). This is where the majority of the logical \"meat\" of your game\ndefinition will live.\n\n5) Often the end result of your game will be a Progressive Web App. You'll\nneed to do a few more things, as described in the boardgame\/server package, to\ncomplete the web app.\n\nReflection and Properties\n\nThe aim of the boardgame package is to make it as easy as possible for you to\nimplement your own boardgames, focusing only on the central semantic logic of\nthe game. The package tries to hit a sweet spot between concrete types whose\nbehavior is modified by delegates, and interfaces that you must implement.\n\nStates, Moves, and Components, in particular, will have a set of properties\nthat is very specific to your particular game and taht particular object type.\nThe package itself tries to rely on reflection only rarely, and only when\ninstructed to. In practice, inside of your Move.Apply, Move.Legal, and\nDelegate methods, you will often immediately cast the provided generic Move,\nState, or Component to the underlying type you know it is.\n\nEvery so often the package has to interact with objects whose shape it does\nnot know. It relies on the PropertyReader and PropertyReadSetter interfaces to\ndo this manipulation. Implementing these methods can be a pain, which is why\nthis package provides a set of implementation methods that rely on reflection\nto satisfy these interfaces.\n\n*\/\npackage boardgame\n<|endoftext|>"}

(Note this is\n\/\/ taken form Python ndb):\n\/\/ Firstly get as many entities from memcache as possible. The returned values\n\/\/ can be in one of three states: No entity, locked value or the acutal entity.\n\/\/\n\/\/ Actual entity case:\n\/\/ If the value from memcache is an actual entity then replensish the local\n\/\/ cache and return that entity to the caller.\n\/\/\n\/\/ Locked entity case:\n\/\/ If the value is locked then just ignore that entity and go to the datastore\n\/\/ to see if it exists.\n\/\/\n\/\/ No entity case:\n\/\/ If no entity is returned from memcache then do the following things to ensure\n\/\/ we don't accidentally update memcache with stale values.\n\/\/ 1) Lock that entity in memcache by setting memcacheLock on that entities key.\n\/\/    Note that the lock timeout is 32 seconds to cater for a datastore edge\n\/\/    case which I currently can't quite remember.\n\/\/ 2) Immediately get that entity back from memcache ensuring the compare and\n\/\/    swap ID is set.\n\/\/ 3) Get the entity from the datastore.\n\/\/ 4) Set the entity in memcache using compare and swap. If this succeeds then\n\/\/    we are guaranteed to have the latest value in memcache. If it fails due\n\/\/    to a CAS failure then there must have been a concurrent write to\n\/\/    memcache and now the memcache for that key is out of action for 32\n\/\/    seconds.\n\/\/\n\/\/ Note that within a transaction, much of this functionality is lost to ensure\n\/\/ datastore consistency.\n\/\/\n\/\/ dst argument must be a slice.\nfunc getMulti(cc *context, keys []*datastore.Key, dst reflect.Value) error {\n\n\tgs := newGetMultiState(keys, dst)\n\n\tif err := loadMemory(cc, gs);

This has the potential\n\/\/ to greatly speed up your entity access and reduce Google App Engine costs.\n\/\/ Note that if you use GetMulti with this packages NewContext, you must do all\n\/\/ your other datastore accesses with other methods from this package to ensure\n\/\/ cache consistency.\n\/\/\n\/\/ Increase the datastore timeout if you get datastore_v3: TIMEOUT errors when\n\/\/ getting thousands of entities.

(Note this is\n\/\/ taken form Python ndb):\n\/\/ Firstly get as many entities from memcache as possible. The returned values\n\/\/ can be in one of three states: No entity, locked value or the acutal entity.\n\/\/\n\/\/ Actual entity case:\n\/\/ If the value from memcache is an actual entity then replensish the local\n\/\/ cache and return that entity to the caller.\n\/\/\n\/\/ Locked entity case:\n\/\/ If the value is locked then just ignore that entity and go to the datastore\n\/\/ to see if it exists.\n\/\/\n\/\/ No entity case:\n\/\/ If no entity is returned from memcache then do the following things to ensure\n\/\/ we don't accidentally update memcache with stale values.\n\/\/ 1) Lock that entity in memcache by setting memcacheLock on that entities key.\n\/\/    Note that the lock timeout is 32 seconds to cater for a datastore edge\n\/\/    case which I currently can't quite remember.\n\/\/ 2) Immediately get that entity back from memcache ensuring the compare and\n\/\/    swap ID is set.\n\/\/ 3) Get the entity from the datastore.\n\/\/ 4) Set the entity in memcache using compare and swap. If this succeeds then\n\/\/    we are guaranteed to have the latest value in memcache. If it fails due\n\/\/    to a CAS failure then there must have been a concurrent write to\n\/\/    memcache and now the memcache for that key is out of action for 32\n\/\/    seconds.\n\/\/\n\/\/ Note that within a transaction, much of this functionality is lost to ensure\n\/\/ datastore consistency.\n\/\/\n\/\/ dst argument must be a slice.\nfunc getMulti(cc *context, keys []*datastore.Key, dst reflect.Value) error {\n\n\tgs := newGetMultiState(keys, dst)\n\n\tif err := loadMemory(cc, gs);

There are arguments both for and against including the deps of tests for any transitive deps. Defer on deciding this for now.\nCopy the relevant versions of the code to the current project’s vendor directory.\nThe source of that code is implementation dependant. Probably some kind of local cache of the VCS data (not a GOPATH\/workspace).\nWrite Manifest (if changed) and Lockfile\nPrint what changed\n\n\nFlags:\n\t-update\t\tupdate all packages\n\t-n\t\t\tdry run\n\t-override <specs>\tspecify an override constraints for package(s)\n\n\nPackage specs:\n\t<path>[:alt location][@<version specifier>]\n\n\nExamples:\nFetch\/update github.com\/heroku\/rollrus to latest version, including transitive dependencies (ensuring it matches the constraints of rollrus, or—if not contrained—their latest versions):\n\t$ dep ensure github.com\/heroku\/rollrus\nSame dep, but choose any minor patch release in the 0.9.X series, setting the constraint. If another constraint exists that constraint is changed to ~0.9.0:\n\t$ dep ensure github.com\/heroku\/rollrus@~0.9.0\nSame dep, but choose any release >= 0.9.1 and < 1.0.0, setting\/changing constraints:\n\t$ dep ensure github.com\/heroku\/rollrus@^0.9.1\nSame dep, but updating to 1.0.X:\n\t$ dep ensure github.com\/heroku\/rollrus@~1.0.0\nSame dep, but fetching from a different location:\n\t$ dep ensure github.com\/heroku\/rollrus:git.example.com\/foo\/bar\nSame dep, but check out a specific version or range without updating the Manifest and update the Lockfile. This will fail if the specified version does not satisfy any existing constraints:\n\t$ dep ensure github.com\/heroku\/rollrus==1.2.3\t# 1.2.3 specifically\n\t$ dep ensure github.com\/heroku\/rollrus=^1.2.0\t# >= 1.2.0  < 2.0.0\nOverride any declared dependency range of 'github.com\/foo\/bar' to have the range of '^0.9.1'. This applies transitively:\n\t$ dep ensure -override github.com\/foo\/bar@^0.9.1\n\n\nTransitive deps are ensured based on constraints in the local Manifest if they exist, then constraints in the dependency’s Manifest file.

There are arguments both for and against including the deps of tests for any transitive deps. Defer on deciding this for now.\nCopy the relevant versions of the code to the current project’s vendor directory.\nThe source of that code is implementation dependant.

If another constraint exists that constraint is changed to ~0.9.0:\n\t$ dep ensure github.com\/heroku\/rollrus@~0.9.0\nSame dep, but choose any release >= 0.9.1 and < 1.0.0, setting\/changing constraints:\n\t$ dep ensure github.com\/heroku\/rollrus@^0.9.1\nSame dep, but updating to 1.0.X:\n\t$ dep ensure github.com\/heroku\/rollrus@~1.0.0\nSame dep, but fetching from a different location:\n\t$ dep ensure github.com\/heroku\/rollrus:git.example.com\/foo\/bar\nSame dep, but check out a specific version or range without updating the Manifest and update the Lockfile. This will fail if the specified version does not satisfy any existing constraints:\n\t$ dep ensure github.com\/heroku\/rollrus==1.2.3\t# 1.2.3 specifically\n\t$ dep ensure github.com\/heroku\/rollrus=^1.2.0\t# >= 1.2.0  < 2.0.0\nOverride any declared dependency range of 'github.com\/foo\/bar' to have the range of '^0.9.1'.
