You need to\nhave access to the app to revoke access from a team.\n\nAn app cannot be orphaned, so it will always have at least one authorized team.\n\n\nSee app's logs\n\nUsage:\n\n\t% tsuru log <appname>\n\nLog will show log entries for an app. These logs are not related to the code of\nthe app itself, but to actions of the app in tsuru server (deployments,\nrestarts, etc.).\n\n\nRun an arbitrary command in the app machine\n\nUsage:\n\n\t% tsuru run <appname> <command> [commandarg1] [commandarg2] ... [commandargn]\n\nRun will run an arbitrary command in the app machine. Base directory for all\ncommands is the root of the app. For example, in a Django app, \"tsuru run\" may\nshow the following output:\n\n\n\t% tsuru run polls ls -l\n\tapp.conf\n\tbrogui\n\tdeploy\n\tfoo\n\t__init__.py\n\t__init__.pyc\n\tmain.go\n\tmanage.py\n\tsettings.py\n\tsettings.pyc\n\ttemplates\n\turls.py\n\turls.pyc\n\n\nRestart the app's application server\n\nUsage:\n\n\t% tsuru restart <appname>\n\nRestart will call the restart hook from the app platform (the \"restart\" hook\nfrom the Juju charm).\n*\/\npackage documentation\n<|endoftext|>"}

This is always followed by a call to ChangedEdges.\n\/\/\n\/\/ Traditionally in D*-lite, the algorithm would scan every edge to see if the cost changed, and then update its information if it detected any changes. This slightly remixed step\n\/\/ allows the graph to provide notification of any changes, and even provide an alternate cost function if it needs to. This can be used to speed up the algorithm significantly\n\/\/ since the graph no longer has to scan for changes, and only updates when told to. If changedEdges is nil or of len 0, no updates will be performed. If changedEdges is not nil, it\n\/\/ will update the internal representation. If newCostFunc is non-nil it will be swapped with dStar's current cost function if and only if changedEdges is non-nil\/len>0, however,\n\/\/ newCostFunc is not required to be non-nil if updates are present. DStar will continue using the current cost function if that is the case.\ntype DStarGraph interface {\n\tGraph\n\tMove(target Node)\n\tChangedEdges() (newCostFunc func(Node, Node) float64, changedEdges []Edge)\n}\n<|endoftext|>"}

Multiple occurrences\ntrigger more verbosity in some commands, including sync.\n\nThe -n flag prints all commands that would be run, but does not run them.\n\nDescriptions of each command follow.\n\nBranchpoint\n\n\tgit codereview branchpoint\n\nThe branchpoint command prints the commit hash of the most recent commit\non the current branch that is shared with the Gerrit server. This is the point\nwhere local work branched from the published tree. The command is intended\nmainly for use in scripts. For example, ``git diff $(git codereview branchpoint)''\nor ``git log $(git codereview branchpoint)..HEAD''.\n\nChange\n\nThe change command creates and moves between Git branches and maintains the\npending changes on work branches.\n\n\tgit codereview change [-a] [-q] [branchname]\n\nGiven a branch name as an argument, the change command switches to the named\nbranch, creating it if necessary. If the branch is created and there are staged\nchanges, it will commit the changes to the branch, creating a new pending\nchange.\n\nWith no argument, the change command creates a new pending change from the\nstaged changes in the current branch or, if there is already a pending change,\namends that change.\n\nThe -q option skips the editing of an extant pending change's commit message.\n\nThe -a option automatically adds any unstaged edits in tracked files during\ncommit; it is equivalent to the 'git commit' -a option.\n\nGofmt\n\nThe gofmt command applies the gofmt program to all files modified in the\ncurrent work branch, both in the staging area (index) and the working tree\n(local directory).\n\n\tgit codereview gofmt [-l]\n\nThe -l option causes the command to list the files that need reformatting but\nnot reformat them. Otherwise, the gofmt command reformats modified files in\nplace. That is, files in the staging area are reformatted in the staging area,\nand files in the working tree are reformatted in the working tree.\n\nHelp\n\nThe help command displays basic usage instructions.\n\n\tgit codereview help\n\nHooks\n\nThe hooks command installs the Git hooks to enforce code review conventions.\n\n\tgit codereview hooks\n\nThe pre-commit hook checks that all Go code is formatted with gofmt and that\nthe commit is not being made directly to the master branch.\n\nThe commit-msg hook adds the Gerrit ``Change-Id'' line to the commit message if\nnot present. It also checks that the message uses the convention established by\nthe Go project that the first line has the form, pkg\/path: summary.\n\nThe hooks command will not overwrite an existing hook.\nIf it is not installing hooks, use ``git codereview hooks -v'' for details.\nThis hook installation is also done at startup by all other git codereview\ncommands, except ``git codereview help''.\n\nHook-Invoke\n\nThe hook-invoke command is an internal command that invokes the named Git hook.\n\n\tgit codereview hook-invoke <hook> [args]\n\nIt is run by the shell scripts installed by the ``git codereview hooks'' command.\n\nMail\n\nThe mail command starts the code review process for the pending change.\n\n\tgit codereview mail [-f] [-r email] [-cc email] [-trybot] [revision]\n\nIt pushes the pending change commit in the current branch to the Gerrit code\nreview server and prints the URL for the change on the server.\nIf the change already exists on the server, the mail command updates that\nchange with a new changeset.\n\nThe -r and -cc flags identify the email addresses of people to do the code\nreview and to be CC'ed about the code review.\nMultiple addresses are given as a comma-separated list.\n\nAn email address passed to -r or -cc can be shortened from name@domain to name.\nThe mail command resolves such shortenings by reading the list of past reviewers\nfrom the git repository log to find email addresses of the form name@somedomain\nand then, in case of ambiguity, using the reviewer who appears most often.\n\nThe -trybot flag runs the trybots on all new or updated changes. It is\nequivalent to setting the Run-Trybot+1 label from Gerrit.\n\nThe mail command fails if there are staged edits that are not committed.\nThe -f flag overrides this behavior.\n\nThe mail command updates the tag <branchname>.mailed to refer to the\ncommit that was most recently mailed, so running ``git diff <branchname>.mailed''\nshows diffs between what is on the Gerrit server and the current directory.\n\nIf there are multiple pending commits, the revision argument is mandatory.\nIf no revision is specified, the mail command prints a short summary of\nthe pending commits for use in deciding which to mail.\n\nIf any commit that would be pushed to the server contains the text\n\"DO NOT MAIL\" (case insensitive) in its commit message, the mail command\nwill refuse to send the commit to the server.\n\nPending\n\nThe pending command prints to standard output the status of all pending changes\nand staged, unstaged, and untracked files in the local repository.\n\n\tgit codereview pending [-c] [-l] [-s]\n\nThe -c flag causes the command to show pending changes only on the current branch.\n\nThe -l flag causes the command to use only locally available information.\nBy default, it fetches recent commits and code review information from the\nGerrit server.\n\nThe -s flag causes the command to print abbreviated (short) output.\n\nCommon shorter aliases include ``git p'' for ``git pending''\nand ``git pl'' for ``git pending -l'' (notably faster but without Gerrit information).\n\nRebase-work\n\nThe rebase-work command runs git rebase in interactive mode over pending changes.\nIt is shorthand for ``git rebase -i $(git codereview branchpoint)''.\nIt differs from plain ``git rebase -i'' in that the latter will try to incorporate\nnew commits from the origin branch during the rebase;\n``git codereview rebase-work'' does not.\n\nIn multiple-commit workflows, rebase-work is used so often\nthat it can be helpful to alias it to ``git rw''.\n\nSubmit\n\nThe submit command pushes the pending change to the Gerrit server and tells\nGerrit to submit it to the master branch.\n\n\tgit codereview submit [-i | revision...]\n\nThe command fails if there are modified files (staged or unstaged) that are not\npart of the pending change.\n\nThe -i option causes the submit command to open a list of commits to submit\nin the configured text editor, similar to ``git rebase -i''.\n\nIf multiple revisions are specified, the submit command submits each one in turn,\nstopping at the first failure.\n\nWhen run in a multiple-commit work branch,\neither the -i option or the revision argument is mandatory.\nIf both are omitted, the submit command prints a short summary of\nthe pending commits for use in deciding which to submit.\n\nAfter submitting the pending changes, the submit command tries to synchronize the\ncurrent branch to the submitted commit, if it can do so cleanly.\nIf not, it will prompt the user to run ``git codereview sync'' manually.\n\nAfter a successful sync, the branch can be used to prepare a new change.\n\nSync\n\nThe sync command updates the local repository.\n\n\tgit codereview sync\n\nIt fetches commits from the remote repository and merges them from the\nupstream branch to the current branch, rebasing any pending changes.\n\nConfiguration\n\nIf a file named codereview.cfg is present in the repository root,\ngit-codereview will use it for configuration.

for\n\/\/ example, to add a \"Martian-Test\" header with the value \"true\" for requests\n\/\/ with the domain \"www.example.com\" the JSON message would be:\n\/\/\n\/\/   {\n\/\/     \"url.Filter\": {\n\/\/       \"scope\": [\"request\"],\n\/\/       \"host\": \"www.example.com\",\n\/\/       \"modifier\": {\n\/\/         \"header.Modifier\": {\n\/\/           \"name\": \"Martian-Test\",\n\/\/           \"value\": \"true\"\n\/\/         }\n\/\/       }\n\/\/     }\n\/\/   }\n\/\/\n\/\/ url.Filter parses the JSON object in the value of the \"url.Filter\" attribute;\n\/\/ the \"host\" key tells the url.Filter to filter requests if the host explicitly\n\/\/ matches \"www.example.com\"\n\/\/\n\/\/ the \"modifier\" key within the \"url.Filter\" JSON object contains another\n\/\/ modifier message of the type header.Modifier to run iff the filter passes\n\/\/\n\/\/ groups may also be used to run multiple modifiers sequentially; for example to\n\/\/ log requests and responses after adding the \"Martian-Test\" header to the\n\/\/ request, but only when the host matches www.example.com:\n\/\/\n\/\/   {\n\/\/     \"url.Filter\": {\n\/\/       \"host\": \"www.example.com\",\n\/\/       \"modifier\": {\n\/\/         \"fifo.Group\": {\n\/\/           \"modifiers\": [\n\/\/             {\n\/\/               \"header.Modifier\": {\n\/\/                 \"scope\": [\"request\"],\n\/\/                 \"name\": \"Martian-Test\",\n\/\/                 \"value\": \"true\"\n\/\/               }\n\/\/             },\n\/\/             {\n\/\/               \"log.Logger\": { }\n\/\/             }\n\/\/           ]\n\/\/         }\n\/\/       }\n\/\/     }\n\/\/   }\n\/\/\n\/\/ modifiers are designed to be composed together in ways that allow the user to\n\/\/ write a single JSON structure to accomplish a variety of functionality\n\/\/\n\/\/   GET http:\/\/martian.proxy\/verify\n\/\/\n\/\/ retrieves the verifications errors as JSON with the following structure:\n\/\/\n\/\/   {\n\/\/     \"errors\": [\n\/\/       {\n\/\/         \"message\": \"request(url) verification failure\"\n\/\/       },\n\/\/       {\n\/\/         \"message\": \"response(url) verification failure\"\n\/\/       }\n\/\/     ]\n\/\/   }\n\/\/\n\/\/ verifiers also adhere to the modifier interface and thus can be included in the\n\/\/ modifier configuration request; for example, to verify that all requests to\n\/\/ \"www.example.com\" are sent over HTTPS send the following JSON to the\n\/\/ configuration endpoint:\n\/\/\n\/\/   {\n\/\/     \"url.Filter\": {\n\/\/       \"scope\": [\"request\"],\n\/\/       \"host\": \"www.example.com\",\n\/\/       \"modifier\": {\n\/\/         \"url.Verifier\": {\n\/\/           \"scope\": [\"request\"],\n\/\/           \"scheme\": \"https\"\n\/\/         }\n\/\/       }\n\/\/     }\n\/\/   }\n\/\/\n\/\/ sending a request to \"http:\/\/martian.proxy\/verify\" will then return errors from the url.Verifier\n\/\/\n\/\/   POST http:\/\/martian.proxy\/verify\/reset\n\/\/\n\/\/ resets the verifiers to their initial state; note some verifiers may start in\n\/\/ a failure state (e.g., pingback.Verifier is failed if no requests have been\n\/\/ seen by the proxy)\n\/\/\n\/\/   GET http:\/\/martian.proxy\/authority.cer\n\/\/\n\/\/ prompts the user to install the CA certificate used by the proxy if MITM is enabled\n\/\/\n\/\/   GET http:\/\/martian.proxy\/logs\n\/\/\n\/\/ retrieves the HAR logs for all requests and responses seen by the proxy if\n\/\/ the HAR flag is enabled\n\/\/\n\/\/   DELETE http:\/\/martian.proxy\/logs\/reset\n\/\/\n\/\/ reset the in-memory HAR log;

for example to\n\/\/ log requests and responses after adding the \"Martian-Test\" header to the\n\/\/ request, but only when the host matches www.example.com:\n\/\/\n\/\/   {\n\/\/     \"url.Filter\": {\n\/\/       \"host\": \"www.example.com\",\n\/\/       \"modifier\": {\n\/\/         \"fifo.Group\": {\n\/\/           \"modifiers\": [\n\/\/             {\n\/\/               \"header.Modifier\": {\n\/\/                 \"scope\": [\"request\"],\n\/\/                 \"name\": \"Martian-Test\",\n\/\/                 \"value\": \"true\"\n\/\/               }\n\/\/             },\n\/\/             {\n\/\/               \"log.Logger\": { }\n\/\/             }\n\/\/           ]\n\/\/         }\n\/\/       }\n\/\/     }\n\/\/   }\n\/\/\n\/\/ modifiers are designed to be composed together in ways that allow the user to\n\/\/ write a single JSON structure to accomplish a variety of functionality\n\/\/\n\/\/   GET http:\/\/martian.proxy\/verify\n\/\/\n\/\/ retrieves the verifications errors as JSON with the following structure:\n\/\/\n\/\/   {\n\/\/     \"errors\": [\n\/\/       {\n\/\/         \"message\": \"request(url) verification failure\"\n\/\/       },\n\/\/       {\n\/\/         \"message\": \"response(url) verification failure\"\n\/\/       }\n\/\/     ]\n\/\/   }\n\/\/\n\/\/ verifiers also adhere to the modifier interface and thus can be included in the\n\/\/ modifier configuration request; for example, to verify that all requests to\n\/\/ \"www.example.com\" are sent over HTTPS send the following JSON to the\n\/\/ configuration endpoint:\n\/\/\n\/\/   {\n\/\/     \"url.Filter\": {\n\/\/       \"scope\": [\"request\"],\n\/\/       \"host\": \"www.example.com\",\n\/\/       \"modifier\": {\n\/\/         \"url.Verifier\": {\n\/\/           \"scope\": [\"request\"],\n\/\/           \"scheme\": \"https\"\n\/\/         }\n\/\/       }\n\/\/     }\n\/\/   }\n\/\/\n\/\/ sending a request to \"http:\/\/martian.proxy\/verify\" will then return errors from the url.Verifier\n\/\/\n\/\/   POST http:\/\/martian.proxy\/verify\/reset\n\/\/\n\/\/ resets the verifiers to their initial state; note some verifiers may start in\n\/\/ a failure state (e.g., pingback.Verifier is failed if no requests have been\n\/\/ seen by the proxy)\n\/\/\n\/\/   GET http:\/\/martian.proxy\/authority.cer\n\/\/\n\/\/ prompts the user to install the CA certificate used by the proxy if MITM is enabled\n\/\/\n\/\/   GET http:\/\/martian.proxy\/logs\n\/\/\n\/\/ retrieves the HAR logs for all requests and responses seen by the proxy if\n\/\/ the HAR flag is enabled\n\/\/\n\/\/   DELETE http:\/\/martian.proxy\/logs\/reset\n\/\/\n\/\/ reset the in-memory HAR log; note that the log will grow unbounded unless it\n\/\/ is periodically reset\n\/\/\n\/\/ passing the -cors flag will enable CORS support for the endpoints so that they\n\/\/ may be called via AJAX\n\/\/\n\/\/ The flags are:\n\/\/   -addr=\":8080\"\n\/\/     host:port of the proxy\n\/\/   -api-addr=\":8181\"\n\/\/     host:port of the proxy API\n\/\/   -tls-addr=\":4443\"\n\/\/     host:port of the proxy over TLS\n\/\/   -api=\"martian.proxy\"\n\/\/     hostname that can be used to reference the configuration API when\n\/\/     configuring through the proxy\n\/\/   -cert=\"\"\n\/\/     PEM encoded X.509 CA certificate;

{"text":"<commit_before>\/\/ Package errors provides simple error handling primitives.\n\/\/\n\/\/ The traditional error handling idiom in Go is roughly akin to\n\/\/\n\/\/     if err != nil {\n\/\/             return err\n\/\/     }\n\/\/\n\/\/ which applied recursively up the call stack results in error reports\n\/\/ without context or debugging information. The errors package allows\n\/\/ programmers to add context to the failure path in their code in a way\n\/\/ that does not destroy the original value of the error.\n\/\/\n\/\/ Adding context to an error\n\/\/\n\/\/ The errors.Wrap function returns a new error that adds context to the\n\/\/ original error. For example\n\/\/\n\/\/     _, err := ioutil.ReadAll(r)\n\/\/     if err != nil {\n\/\/             return errors.Wrap(err, \"read failed\")\n\/\/     }\n\/\/\n\/\/ Retrieving the cause of an error\n\/\/\n\/\/ Using errors.Wrap constructs a stack of errors, adding context to the\n\/\/ preceding error. Depending on the nature of the error it may be necessary\n\/\/ to reverse the operation of errors.Wrap to retrieve the original error\n\/\/ for inspection. Any error value which implements this interface\n\/\/\n\/\/     type causer interface {\n\/\/             Cause() error\n\/\/     }\n\/\/\n\/\/ can be inspected by errors.Cause. errors.Cause will recursively retrieve\n\/\/ the topmost error which does not implement causer, which is assumed to be\n\/\/ the original cause. For example:\n\/\/\n\/\/     switch err := errors.Cause(err).(type) {\n\/\/     case *MyError:\n\/\/             \/\/ handle specifically\n\/\/     default:\n\/\/             \/\/ unknown error\n\/\/     }\n\/\/\n\/\/ causer interface is not exported by this package, but is considered a part\n\/\/ of stable public API.\n\/\/\n\/\/ Formatted printing of errors\n\/\/\n\/\/ All error values returned from this package implement fmt.Formatter and can\n\/\/ be formatted by the fmt package. The following verbs are supported\n\/\/\n\/\/     %s    print the error. If the error has a Cause it will be\n\/\/           printed recursively\n\/\/     %v    see %s\n\/\/     %+v   extended format. Each Frame of the error's StackTrace will\n\/\/           be printed in detail.\n\/\/\n\/\/ Retrieving the stack trace of an error or wrapper\n\/\/\n\/\/ New, Errorf, Wrap, and Wrapf record a stack trace at the point they are\n\/\/ invoked.

For example\n\/\/\n\/\/     _, err := ioutil.ReadAll(r)\n\/\/     if err != nil {\n\/\/             return errors.Wrap(err, \"read failed\")\n\/\/     }\n\/\/\n\/\/ Retrieving the cause of an error\n\/\/\n\/\/ Using errors.Wrap constructs a stack of errors, adding context to the\n\/\/ preceding error.

{"text":"<commit_before>\/\/ Package httpexpect helps to write nice tests for your HTTP API.\n\/\/\n\/\/ Usage examples\n\/\/\n\/\/ See example directory:\n\/\/  - https:\/\/godoc.org\/github.com\/gavv\/httpexpect\/example\n\/\/  - https:\/\/github.com\/gavv\/httpexpect\/tree\/master\/example\n\/\/\n\/\/ Communication mode\n\/\/\n\/\/ There are two common ways to test API with httpexpect:\n\/\/  - start HTTP server and instruct httpexpect to use HTTP client for communication\n\/\/  - don't start server and instruct httpexpect to invoke http handler directly\n\/\/\n\/\/ The second approach works only if the server is a Go module and its handler can\n\/\/ be imported in tests.\n\/\/\n\/\/ Concrete behaviour is determined by Client implementation passed to Config struct.\n\/\/ If you're using http.Client, set its Transport field (http.RoundTriper) to one of\n\/\/ the following:\n\/\/  1. default (nil) - use regular HTTP transport from net\/http (you should start server)\n\/\/  2. httpexpect.Binder - invoke given http.Handler directly\n\/\/  4. httpexpect.FastBinder - invoke given fasthttp.RequestHandler directly\n\/\/\n\/\/ Note that http handler can be usually obtained from http framework you're using.\n\/\/ E.g., echo framework provides either http.Handler or fasthttp.RequestHandler.\n\/\/\n\/\/ You can also provide your own Client or http.RoundTriper implementation and do\n\/\/ whatever you want to convert http.Request to http.Response.\n\/\/\n\/\/ If you're starting server from tests, it's very handy to use net\/http\/httptest\n\/\/ for that.\n\/\/\n\/\/ Value equality\n\/\/\n\/\/ Whenever values are checked for equality in httpexpect, they are converted\n\/\/ to \"canonical form\":\n\/\/  - type aliases are removed\n\/\/  - numeric types are converted to float64\n\/\/  - non-nil interfaces pointing to nil slices and maps are replaced with nil interfaces\n\/\/  - structs are converted to map[string]interface{}\n\/\/\n\/\/ This is equivalent to subsequently json.Marshal() and json.Unmarshal() the value\n\/\/ and currently is implemented so.\n\/\/\n\/\/ Failure handling\n\/\/\n\/\/ When some check fails, failure is reported. If non-fatal failures are used\n\/\/ (see Reporter interface), execution is continued and instance that was checked\n\/\/ is marked as failed.\n\/\/\n\/\/ If specific instance is marked as failed, all subsequent checks are ignored\n\/\/ for this instance and for any child instances retrieved after failure.\n\/\/\n\/\/ Example:\n\/\/  array := NewArray(NewAssertReporter(t), []interface{}{\"foo\", 123})\n\/\/\n\/\/  e0 := array.Element(0)  \/\/ success\n\/\/  e1 := array.Element(1)  \/\/ success\n\/\/\n\/\/  s0 := e0.String()       \/\/ success\n\/\/  s1 := e1.String()       \/\/ failure; e1 and s1 are marked as failed, e0 and s0 are not\n\/\/\n\/\/  s0.Equal(\"foo\")         \/\/ success\n\/\/  s1.Equal(\"bar\")         \/\/ this check is ignored because s1 is marked as failed\npackage httpexpect\n\nimport (\n\t\"golang.org\/x\/net\/publicsuffix\"\n\t\"net\/http\"\n\t\"net\/http\/cookiejar\"\n\t\"testing\"\n\t\"time\"\n)\n\n\/\/ Expect is a toplevel object that contains user Config and allows\n\/\/ to construct Request objects.\ntype Expect struct {\n\tconfig   Config\n\tbuilders []func(*Request)\n}\n\n\/\/ Config contains various settings.\ntype Config struct {\n\t\/\/ BaseURL is a URL to prepended to all request.

https:\/\/godoc.org\/github.com\/gavv\/httpexpect\/example\n\/\/  - https:\/\/github.com\/gavv\/httpexpect\/tree\/master\/example\n\/\/\n\/\/ Communication mode\n\/\/\n\/\/ There are two common ways to test API with httpexpect:\n\/\/  - start HTTP server and instruct httpexpect to use HTTP client for communication\n\/\/  - don't start server and instruct httpexpect to invoke http handler directly\n\/\/\n\/\/ The second approach works only if the server is a Go module and its handler can\n\/\/ be imported in tests.\n\/\/\n\/\/ Concrete behaviour is determined by Client implementation passed to Config struct.\n\/\/ If you're using http.Client, set its Transport field (http.RoundTriper) to one of\n\/\/ the following:\n\/\/  1. default (nil) - use regular HTTP transport from net\/http (you should start server)\n\/\/  2. httpexpect.Binder - invoke given http.Handler directly\n\/\/  4. httpexpect.FastBinder - invoke given fasthttp.RequestHandler directly\n\/\/\n\/\/ Note that http handler can be usually obtained from http framework you're using.\n\/\/ E.g., echo framework provides either http.Handler or fasthttp.RequestHandler.\n\/\/\n\/\/ You can also provide your own Client or http.RoundTriper implementation and do\n\/\/ whatever you want to convert http.Request to http.Response.\n\/\/\n\/\/ If you're starting server from tests, it's very handy to use net\/http\/httptest\n\/\/ for that.\n\/\/\n\/\/ Value equality\n\/\/\n\/\/ Whenever values are checked for equality in httpexpect, they are converted\n\/\/ to \"canonical form\":\n\/\/  - type aliases are removed\n\/\/  - numeric types are converted to float64\n\/\/  - non-nil interfaces pointing to nil slices and maps are replaced with nil interfaces\n\/\/  - structs are converted to map[string]interface{}\n\/\/\n\/\/ This is equivalent to subsequently json.Marshal() and json.Unmarshal() the value\n\/\/ and currently is implemented so.\n\/\/\n\/\/ Failure handling\n\/\/\n\/\/ When some check fails, failure is reported. If non-fatal failures are used\n\/\/ (see Reporter interface), execution is continued and instance that was checked\n\/\/ is marked as failed.\n\/\/\n\/\/ If specific instance is marked as failed, all subsequent checks are ignored\n\/\/ for this instance and for any child instances retrieved after failure.\n\/\/\n\/\/ Example:\n\/\/  array := NewArray(NewAssertReporter(t), []interface{}{\"foo\", 123})\n\/\/\n\/\/  e0 := array.Element(0)  \/\/ success\n\/\/  e1 := array.Element(1)  \/\/ success\n\/\/\n\/\/  s0 := e0.String()       \/\/ success\n\/\/  s1 := e1.String()       \/\/ failure; e1 and s1 are marked as failed, e0 and s0 are not\n\/\/\n\/\/  s0.Equal(\"foo\")         \/\/ success\n\/\/  s1.Equal(\"bar\")         \/\/ this check is ignored because s1 is marked as failed\npackage httpexpect\n\nimport (\n\t\"golang.org\/x\/net\/publicsuffix\"\n\t\"net\/http\"\n\t\"net\/http\/cookiejar\"\n\t\"testing\"\n\t\"time\"\n)\n\n\/\/ Expect is a toplevel object that contains user Config and allows\n\/\/ to construct Request objects.\ntype Expect struct {\n\tconfig   Config\n\tbuilders []func(*Request)\n}\n\n\/\/ Config contains various settings.\ntype Config struct {\n\t\/\/ BaseURL is a URL to prepended to all request.

Looking at the travis-logs source, the\n\t\/\/ current message overhead (i.e. the part of the payload that isn't\n\t\/\/ the content of the log part) is 42 bytes + the length of the JSON-\n\t\/\/ encoded ID and the length of the JSON-encoded sequence number. A 64-\n\t\/\/ bit number is up to 20 digits long, so that means (assuming we don't\n\t\/\/ go over 64-bit numbers) the overhead is up to 82 bytes. That means\n\t\/\/ we can send up to 9918 bytes of content. However, the JSON-encoded\n\t\/\/ version of a string can be significantly longer than the raw bytes.\n\t\/\/ Worst case that I could find is \"<\", which with the Go JSON encoder\n\t\/\/ becomes \"\\u003c\" (i.e. six bytes long). So, given a string of just\n\t\/\/ left angle brackets, the string would become six times as long,\n\t\/\/ meaning that the longest string we can take is 1653.

If the -src flag is specified,\ngodoc prints the exported interface of a package in Go source form, or the\nimplementation of a specific exported language entity:\n\n\tgodoc fmt                # documentation for package fmt\n\tgodoc fmt Printf         # documentation for fmt.Printf\n\tgodoc -src fmt           # fmt package interface in Go source form\n\tgodoc -src fmt Printf    # implementation of fmt.Printf\n\nIn command-line mode, the -q flag enables search queries against a godoc running\nas a webserver. If no explicit server address is specified with the -server flag,\ngodoc first tries localhost:6060 and then http:\/\/golang.org.\n\n\tgodoc -q Reader Writer\n\tgodoc -q math.Sin\n\tgodoc -server=:6060 -q sin\n\nWith the -http flag, it runs as a web server and presents the documentation as a\nweb page.\n\n\tgodoc -http=:6060\n\nUsage:\n\tgodoc [flag] package [name ...]\n\nThe flags are:\n\t-v\n\t\tverbose mode\n\t-q\n\t\targuments are considered search queries: a legal query is a\n\t\tsingle identifier (such as ToLower) or a qualified identifier\n\t\t(such as math.Sin).\n\t-src\n\t\tprint (exported) source in command-line mode\n\t-tabwidth=4\n\t\twidth of tabs in units of spaces\n\t-timestamps=true\n\t\tshow timestamps with directory listings\n\t-path=\"\"\n\t\tadditional package directories (colon-separated)\n\t-html\n\t\tprint HTML in command-line mode\n\t-goroot=$GOROOT\n\t\tGo root directory\n\t-http=addr\n\t\tHTTP service address (e.g., '127.0.0.1:6060' or just ':6060')\n\t-server=addr\n\t\twebserver address for command line searches\n\t-sync=\"command\"\n\t\tif this and -sync_minutes are set, run the argument as a\n\t\tcommand every sync_minutes; it is intended to update the\n\t\trepository holding the source files.\n\t-sync_minutes=0\n\t\tsync interval in minutes; sync is disabled if <= 0\n\t-filter=\"\"\n\t\tfilter file containing permitted package directory paths\n\t-filter_minutes=0\n\t\tfilter file update interval in minutes; update is disabled if <= 0\n\nThe -path flag accepts a list of colon-separated paths; unrooted paths are relative\nto the current working directory. Each path is considered as an additional root for\npackages in order of appearance. The last (absolute) path element is the prefix for\nthe package path. For instance, given the flag value:\n\n\tpath=\".:\/home\/bar:\/public\"\n\nfor a godoc started in \/home\/user\/godoc, absolute paths are mapped to package paths\nas follows:\n\n\t\/home\/user\/godoc\/x -> godoc\/x\n\t\/home\/bar\/x        -> bar\/x\n\t\/public\/x          -> public\/x\n\nPaths provided via -path may point to very large file systems that contain\nnon-Go files. Creating the subtree of directories with Go packages may take\na long amount of time. A file containing newline-separated directory paths\nmay be provided with the -filter flag; if it exists, only directories\non those paths are considered. If -filter_minutes is set, the filter_file is\nupdated regularly by walking the entire directory tree.\n\nWhen godoc runs as a web server, it creates a search index from all .go files\nunder -goroot (excluding files starting with .).

This object will be\n\/\/ responsible for loading your configuration. It does not yet know about the\n\/\/ different transports, peer lists, etc. that you want to use. You can inform\n\/\/ the Configurator about the different transports, peer lists, etc. by\n\/\/ registering them using RegisterTransport, RegisterPeerChooser,\n\/\/ RegisterPeerList, and RegisterPeerListUpdater.\n\/\/\n\/\/ \tcfg := config.New()\n\/\/ \tcfg.MustRegisterTransport(http.TransportSpec())\n\/\/ \tcfg.MustRegisterPeerList(roundrobin.Spec())\n\/\/\n\/\/ This object is re-usable and may be stored as a singleton in your\n\/\/ application. Custom transports, peer lists, and peer list updaters may be\n\/\/ integrated with the configuration system by registering more\n\/\/ TransportSpecs, PeerChooserSpecs, PeerListSpecs, and PeerListUpdaterSpecs\n\/\/ with it.\n\/\/\n\/\/ Use LoadConfigFromYAML to load a yarpc.Config from YAML and pass that to\n\/\/ yarpc.NewDispatcher.\n\/\/\n\/\/ \tc, err := cfg.LoadConfigFromYAML(\"myservice\", yamlConfig)\n\/\/ \tif err != nil {\n\/\/ \t\tlog.Fatal(err)\n\/\/ \t}\n\/\/ \tdispatcher := yarpc.NewDispatcher(c)\n\/\/\n\/\/ If you have already parsed your configuration from a different format, pass\n\/\/ the parsed data to LoadConfig instead.\n\/\/\n\/\/ \tvar m map[string]interface{} = ...\n\/\/ \tc, err := cfg.LoadConfig(\"myservice\", m)\n\/\/ \tif err != nil {\n\/\/ \t\tlog.Fatal(err)\n\/\/ \t}\n\/\/ \tdispatcher := yarpc.NewDispatcher(c)\n\/\/\n\/\/ NewDispatcher or NewDispatcherFromYAML may be used to get a\n\/\/ yarpc.Dispatcher directly instead of a yarpc.Config.\n\/\/\n\/\/ \tdispatcher, err := cfg.NewDispatcherFromYAML(\"myservice\", yamlConfig)\n\/\/\n\/\/ Configuration parameters for the different transports, inbounds, and\n\/\/ outbounds are defined in the TransportSpecs that were registered against\n\/\/ the Configurator. A TransportSpec uses this information to build the\n\/\/ corresponding Transport, Inbound and Outbound objects.\n\/\/\n\/\/ Configuration\n\/\/\n\/\/ The configuration may be specified in YAML or as any Go-level\n\/\/ map[string]interface{}. The examples below use YAML for illustration\n\/\/ purposes but other markup formats may be parsed into map[string]interface{}\n\/\/ as long as the information provided is the same.\n\/\/\n\/\/ The configuration accepts the following top-level attributes: transports,\n\/\/ inbounds, and outbounds.\n\/\/\n\/\/ \tinbounds:\n\/\/ \t  # ...\n\/\/ \toutbounds:\n\/\/ \t  # ...\n\/\/ \ttransports:\n\/\/ \t  # ...\n\/\/\n\/\/ See the following sections for details on the transports, inbounds, and\n\/\/ outbounds keys in the configuration.\n\/\/\n\/\/ Inbound Configuration\n\/\/\n\/\/ The 'inbounds' attribute configures the different ways in which the service\n\/\/ receives requests. It is represented as a mapping between inbound transport\n\/\/ type and its configuration. For example, the following states that we want\n\/\/ to receive requests over HTTP.\n\/\/\n\/\/ \tinbounds:\n\/\/ \t  http:\n\/\/ \t    address: :8080\n\/\/\n\/\/ (For details on the configuration parameters of individual transport types,\n\/\/ check the documentation for the corresponding transport package.)\n\/\/\n\/\/ If you want multiple inbounds of the same type, specify a different name\n\/\/ for it and add a 'type' attribute to its configuration:\n\/\/\n\/\/ \tinbounds:\n\/\/ \t  http:\n\/\/ \t    address: :8081\n\/\/ \t  http-deprecated:\n\/\/ \t    type: http\n\/\/ \t    address: :8080\n\/\/\n\/\/ Any inbound can be disabled by adding a 'disabled' attribute.\n\/\/\n\/\/ \tinbounds:\n\/\/ \t  http:\n\/\/ \t    address: :8080\n\/\/ \t  http-deprecated:\n\/\/ \t    type: http\n\/\/ \t    disabled: true\n\/\/ \t    address: :8081\n\/\/\n\/\/ Outbound Configuration\n\/\/\n\/\/ The 'outbounds' attribute configures how this service makes requests to\n\/\/ other YARPC-compatible services. It is represented as mapping between\n\/\/ service name and outbound configuration.\n\/\/\n\/\/ \toutbounds:\n\/\/ \t  keyvalue:\n\/\/ \t    # ..\n\/\/ \t  anotherservice:\n\/\/ \t    # ..\n\/\/\n\/\/ (For details on the configuration parameters of individual transport types,\n\/\/ check the documentation for the corresponding transport package.)\n\/\/\n\/\/ The outbound configuration for a service has at least one of the following\n\/\/ keys: unary, oneway. These specify the configurations for the corresponding\n\/\/ RPC types for that service.

This object will be\n\/\/ responsible for loading your configuration. It does not yet know about the\n\/\/ different transports, peer lists, etc. that you want to use. You can inform\n\/\/ the Configurator about the different transports, peer lists, etc. by\n\/\/ registering them using RegisterTransport, RegisterPeerChooser,\n\/\/ RegisterPeerList, and RegisterPeerListUpdater.\n\/\/\n\/\/ \tcfg := config.New()\n\/\/ \tcfg.MustRegisterTransport(http.TransportSpec())\n\/\/ \tcfg.MustRegisterPeerList(roundrobin.Spec())\n\/\/\n\/\/ This object is re-usable and may be stored as a singleton in your\n\/\/ application. Custom transports, peer lists, and peer list updaters may be\n\/\/ integrated with the configuration system by registering more\n\/\/ TransportSpecs, PeerChooserSpecs, PeerListSpecs, and PeerListUpdaterSpecs\n\/\/ with it.\n\/\/\n\/\/ Use LoadConfigFromYAML to load a yarpc.Config from YAML and pass that to\n\/\/ yarpc.NewDispatcher.\n\/\/\n\/\/ \tc, err := cfg.LoadConfigFromYAML(\"myservice\", yamlConfig)\n\/\/ \tif err != nil {\n\/\/ \t\tlog.Fatal(err)\n\/\/ \t}\n\/\/ \tdispatcher := yarpc.NewDispatcher(c)\n\/\/\n\/\/ If you have already parsed your configuration from a different format, pass\n\/\/ the parsed data to LoadConfig instead.\n\/\/\n\/\/ \tvar m map[string]interface{} = ...\n\/\/ \tc, err := cfg.LoadConfig(\"myservice\", m)\n\/\/ \tif err != nil {\n\/\/ \t\tlog.Fatal(err)\n\/\/ \t}\n\/\/ \tdispatcher := yarpc.NewDispatcher(c)\n\/\/\n\/\/ NewDispatcher or NewDispatcherFromYAML may be used to get a\n\/\/ yarpc.Dispatcher directly instead of a yarpc.Config.\n\/\/\n\/\/ \tdispatcher, err := cfg.NewDispatcherFromYAML(\"myservice\", yamlConfig)\n\/\/\n\/\/ Configuration parameters for the different transports, inbounds, and\n\/\/ outbounds are defined in the TransportSpecs that were registered against\n\/\/ the Configurator. A TransportSpec uses this information to build the\n\/\/ corresponding Transport, Inbound and Outbound objects.\n\/\/\n\/\/ Configuration\n\/\/\n\/\/ The configuration may be specified in YAML or as any Go-level\n\/\/ map[string]interface{}. The examples below use YAML for illustration\n\/\/ purposes but other markup formats may be parsed into map[string]interface{}\n\/\/ as long as the information provided is the same.\n\/\/\n\/\/ The configuration accepts the following top-level attributes: transports,\n\/\/ inbounds, and outbounds.\n\/\/\n\/\/ \tinbounds:\n\/\/ \t  # ...\n\/\/ \toutbounds:\n\/\/ \t  # ...\n\/\/ \ttransports:\n\/\/ \t  # ...\n\/\/ \tlogging:\n\/\/ \t  # ...\n\/\/\n\/\/ See the following sections for details on the logging, transports,\n\/\/ inbounds, and outbounds keys in the configuration.\n\/\/\n\/\/ Inbound Configuration\n\/\/\n\/\/ The 'inbounds' attribute configures the different ways in which the service\n\/\/ receives requests. It is represented as a mapping between inbound transport\n\/\/ type and its configuration. For example, the following states that we want\n\/\/ to receive requests over HTTP.\n\/\/\n\/\/ \tinbounds:\n\/\/ \t  http:\n\/\/ \t    address: :8080\n\/\/\n\/\/ (For details on the configuration parameters of individual transport types,\n\/\/ check the documentation for the corresponding transport package.)\n\/\/\n\/\/ If you want multiple inbounds of the same type, specify a different name\n\/\/ for it and add a 'type' attribute to its configuration:\n\/\/\n\/\/ \tinbounds:\n\/\/ \t  http:\n\/\/ \t    address: :8081\n\/\/ \t  http-deprecated:\n\/\/ \t    type: http\n\/\/ \t    address: :8080\n\/\/\n\/\/ Any inbound can be disabled by adding a 'disabled' attribute.\n\/\/\n\/\/ \tinbounds:\n\/\/ \t  http:\n\/\/ \t    address: :8080\n\/\/ \t  http-deprecated:\n\/\/ \t    type: http\n\/\/ \t    disabled: true\n\/\/ \t    address: :8081\n\/\/\n\/\/ Outbound Configuration\n\/\/\n\/\/ The 'outbounds' attribute configures how this service makes requests to\n\/\/ other YARPC-compatible services.
