#ValidationTags#CodeStyle,Messaging,FlowControl,Pipeline# function Install-DbaSqlWatch { <# .SYNOPSIS Installs or updates SqlWatch. .DESCRIPTION Downloads, extracts and installs or updates SqlWatch. https://sqlwatch.io/ .PARAMETER SqlInstance SQL Server name or SMO object representing the SQL Server to connect to. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER Database Specifies the database to install SqlWatch into. Defaults to SQLWATCH. .PARAMETER LocalFile Specifies the path to a local file to install SqlWatch from. This *should* be the zipfile as distributed by the maintainers. If this parameter is not specified, the latest version will be downloaded and installed from https://github.com/marcingminski/sqlwatch .PARAMETER Force If this switch is enabled, SqlWatch will be downloaded from the internet even if previously cached. .PARAMETER PreRelease If specified, a pre-release (beta) will be downloaded rather than a stable release .PARAMETER Confirm Prompts to confirm actions .PARAMETER WhatIf Shows what would happen if the command were to run. No actions are actually performed. .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .NOTES Tags: SqlWatch Author: Ken K (github.com/koglerk) Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Install-DbaSqlWatch .EXAMPLE Install-DbaSqlWatch -SqlInstance server1 Logs into server1 with Windows authentication and then installs SqlWatch in the SQLWATCH database. .EXAMPLE Install-DbaSqlWatch -SqlInstance server1\instance1 -Database DBA Logs into server1\instance1 with Windows authentication and then installs SqlWatch in the DBA database. .EXAMPLE Install-DbaSqlWatch -SqlInstance server1\instance1 -Database DBA -SqlCredential $cred Logs into server1\instance1 with SQL authentication and then installs SqlWatch in the DBA database. .EXAMPLE Install-DbaSqlWatch -SqlInstance sql2016\standardrtm, sql2016\sqlexpress, sql2014 Logs into sql2016\standardrtm, sql2016\sqlexpress and sql2014 with Windows authentication and then installs SqlWatch in the SQLWATCH database. .EXAMPLE $servers = "sql2016\standardrtm", "sql2016\sqlexpress", "sql2014" $servers | Install-DbaSqlWatch Logs into sql2016\standardrtm, sql2016\sqlexpress and sql2014 with Windows authentication and then installs SqlWatch in the SQLWATCH database. #> [CmdletBinding(SupportsShouldProcess, ConfirmImpact = "Low")] param ( [Parameter(Mandatory, ValueFromPipeline)] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [string]$Database = "SQLWATCH", [string]$LocalFile, [switch]$PreRelease, [switch]$Force, [switch]$EnableException ) begin { $stepCounter = 0 $DbatoolsData = Get-DbatoolsConfigValue -FullName "Path.DbatoolsData" $tempFolder = ([System.IO.Path]::GetTempPath()).TrimEnd("\") $zipfile = "$tempFolder\SqlWatch.zip" $releasetxt = $(if ($PreRelease) {"pre-release"} else {"release"}) if (-not $LocalFile) { if ($PSCmdlet.ShouldProcess($env:computername, "Downloading latest $releasetxt from GitHub")) { Write-ProgressHelper -StepNumber ($stepCounter++) -Message "Downloading latest release from GitHub" # query the releases to find the latest, check and see if its cached $ReleasesUrl = "https://api.github.com/repos/marcingminski/sqlwatch/releases" $DownloadBase = "https://github.com/marcingminski/sqlwatch/releases/download/" Write-Message -Level Verbose -Message "Checking GitHub for the latest $releasetxt." $LatestReleaseUrl = ((Invoke-TlsWebRequest -UseBasicParsing -Uri $ReleasesUrl | ConvertFrom-Json) | Where-Object { $_.prerelease -eq $PreRelease })[0].assets[0].browser_download_url Write-Message -Level VeryVerbose -Message "Latest $releasetxt is available at $LatestReleaseUrl" $LocallyCachedZip = Join-Path -Path $DbatoolsData -ChildPath $($LatestReleaseUrl -replace $DownloadBase, ''); # if local cached copy exists, use it, otherwise download a new one if (-not $Force) { # download from github Write-Message -Level Verbose "Downloading $LatestReleaseUrl" try { Invoke-TlsWebRequest $LatestReleaseUrl -OutFile $zipfile -ErrorAction Stop -UseBasicParsing } catch { #try with default proxy and usersettings (New-Object System.Net.WebClient).Proxy.Credentials = [System.Net.CredentialCache]::DefaultNetworkCredentials Invoke-TlsWebRequest $LatestReleaseUrl -OutFile $zipfile -ErrorAction Stop -UseBasicParsing } # copy the file from temp to local cache Write-Message -Level Verbose "Copying $zipfile to $LocallyCachedZip" try { New-Item -Path $LocallyCachedZip -ItemType File -Force | Out-Null Copy-Item -Path $zipfile -Destination $LocallyCachedZip -Force } catch { # should we stop the function if the file copy fails? # here to avoid an empty catch $null = 1 } } } } else { # $LocalFile was passed, so use it if ($PSCmdlet.ShouldProcess($env:computername, "Copying local file to temp directory")) { if ($LocalFile.EndsWith("zip")) { $LocallyCachedZip = $zipfile Copy-Item -Path $LocalFile -Destination $LocallyCachedZip -Force } else { $LocallyCachedZip = (Join-Path -path $tempFolder -childpath "SqlWatch.zip") Copy-Item -Path $LocalFile -Destination $LocallyCachedZip -Force } } } # expand the zip file if ($PSCmdlet.ShouldProcess($env:computername, "Unpacking zipfile")) { Write-Message -Level VeryVerbose "Unblocking $LocallyCachedZip" Unblock-File $LocallyCachedZip -ErrorAction SilentlyContinue $LocalCacheFolder = Split-Path $LocallyCachedZip -Parent Write-Message -Level Verbose "Extracting $LocallyCachedZip to $LocalCacheFolder" if (Get-Command -ErrorAction SilentlyContinue -Name "Expand-Archive") { try { Expand-Archive -Path $LocallyCachedZip -DestinationPath $LocalCacheFolder -Force } catch { Stop-Function -Message "Unable to extract $LocallyCachedZip.
