The information that can be preserved is Created Time, Last Write Time and Attributes (e.g. Read Only). +1. AzCopy can now transfer empty folders, and also transfer the properties of folders. This applies when both the source +and destination support real folders (Blob Storage does not, because it only supports virtual folders). +1. On Windows, AzCopy can now activate the special privileges `SeBackupPrivilege` and `SeRestorePrivilege`. Most admin-level +accounts have these privileges in a deactivated state, as do all members of the "Backup Operators" security group. +If you run AzCopy as one of those users +and supply the new flag `--backup`, AzCopy will activate the privileges. (Use an elevated command prompt, if running as Admin). +At upload time, this allows AzCopy to read files +which you wouldn't otherwise have permission to see. At download time, it works with the `--preserve-smb-permissions` flag +to allow preservation of permissions where the Owner is not the user running AzCopy. The `--backup` flag will report a failure +if the privileges cannot be activated. +1. Status output from AzCopy `copy`, `sync`, `jobs list`, and `jobs status` now contains information about folders. + This includes new properties in the JSON output of copy, sync, list and jobs status commands, when `--output-type + json` is used. +1. Empty folders are deleted when using `azcopy rm` on Azure Files. +1. Snapshots of Azure File Shares are supported, for read-only access, in `copy`,`sync` and `list`. To use, add a + `sharesnapshot` parameter at end of URL for your Azure Files source. Remember to separate it from the existing query + string parameters (i.e. the SAS token) with a `&`. E.g. + `https://.file.core.windows.net/sharename?st=2020-03-03T20%3A53%3A48Z&se=2020-03-04T20%3A53%3A48Z&sp=rl&sv=2018-03-28&sr=s&sig=REDACTED&sharesnapshot=2020-03-03T20%3A24%3A13.0000000Z` +1. Benchmark mode is now supported for Azure Files and ADLS Gen 2 (in addition to the existing benchmark support for + Blob Storage). +1. A special performance optimization is introduced, but only for NON-recursive cases in this release. An `--include-pattern` that contains only `*` wildcards will be performance optimized when + querying blob storage without the recursive flag. The section before the first `*` will be used as a server-side prefix, to filter the search results more efficiently. E.g. `--include-pattern abc*` will be implemented +as a prefix search for "abc". In a more complex example, `--include-pattern abc*123`, will be implemented as a prefix search for `abc`, followed by normal filtering for all matches of `abc*123`. To non-recursively process blobs +contained directly in a container or virtual directory include `/*` at the end of the URL (before the query string). E.g. `http://account.blob.core.windows.net/container/*?`. +1. The `--cap-mbps` parameter now parses floating-point numbers. This will allow you to limit your maximum throughput to a fraction of a megabit per second. + +### Special notes + +1. A more user-friendly error message is returned when an unknown source/destination combination is supplied +1. AzCopy has upgraded to service revision `2019-02-02`. Users targeting local emulators, Azure Stack, or other private/special + instances of Azure Storage may need to intentionally downgrade their service revision using the environment variable + `AZCOPY_DEFAULT_SERVICE_API_VERSION`. Prior to this release, the default service revision was `2018-03-28`. +1. For Azure Files to Azure Files transfers, --persist-smb-permissions and --persist-smb-info are available on all OS's. +(But for for uploads and downloads, those flags are only available on Windows.) +1. AzCopy now includes a list of trusted domain suffixes for Azure Active Directory (AAD) authentication. + After `azcopy login`, the resulting token will only be sent to locations that appear in the list. The list is: + `*.core.windows.net;*.core.chinacloudapi.cn;*.core.cloudapi.de;*.core.usgovcloudapi.net`. + If necessary, you can add to the the list with the command-line flag: `--trusted-microsoft-suffixes`. For security, + you should only add Microsoft Azure domains. +1. When transferring over a million files, AzCopy will reduces its progress reporting frequency from every 2 seconds to every 2 minutes. + +### Breaking changes -1. Any `--include-pattern` that contains only `*` wildcards will be performance optimized when querying blob storage. The section before the -first `*` will be used as a server-side prefix, to filter the search results more efficiently. E.g. "--include-path abc*" will be implemented -as a prefix search for "abc". In a more complex example, "--include-path abc\*123", will be implemented as a prefix search for "abc", followed -by client-side filtering to find exact matches to abc\*123. -2. When processing over a million files, AzCopy will report on its progress once ever 2 minutes instead of once every 2 seconds. This reduces the CPU -load associated with progress reporting. +1. To accommodate interfacing with JavaScript programs (and other languages that have similar issue with number precision), + all the numbers in the JSON output have been converted to strings (i.e. with quotes around them). +1. The TransferStatus value `SkippedFileAlreadyExists` has been renamed `SkippedEntityExists` and may now be used both + for when files are skipped and for when the setting of folder properties is skipped. This affects the input and + output of `azcopy jobs show` and the status values shown in the JSON output format from `copy` and `sync`. +1. The format and content of authentication information messages, in the JSON output format, e.g. + "Using OAuth token for authentication" has been changed. +### Bug fixes + +1. AzCopy can now overwrite even Read-Only and Hidden files when downloading to Windows. (The read-only case requires the use of + the new `--force-if-read-only` flag.) +1. Fixed a nil dereference when a prefetching error occurs in a upload +1. Fixed a nil dereference when attempting to close a log file while log-level is none +1. AzCopy's scanning of Azure Files sources, for download or Service to Service transfers, is now much faster. +1. Sources and destinations that are identified by their IPv4 address can now be used. This enables usage with storage + emulators. Note that the `from-to` flag is typically needed when using such sources or destinations. E.g. `--from-to + BlobLocal` if downloading from a blob storage emulator to local disk. +1. Filenames containing the character `:` can now safely be downloaded on Windows and uploaded to Azure Files +1. Objects with names containing `+` can now safely be used in imported S3 object names +1. The `check-length` flag is now exposed in benchmark mode, so that length checking can be turned off for more speed, + when benchmarking with small file sizes. (When using large file sizes, the overhead of the length check is + insignificant.) +1. The in-app documentation for Service Principal Authentication has been corrected, to now include the application-id + parameter. +1. ALL filter types are now disallowed when running `azcopy rm` against ADLS Gen2 endpoints. Previously +include/exclude patterns were disallowed, but exclude-path was not. That was incorrect. All should have been +disallowed because none (other than include-path) are respected. + ## Version 10.3.4 ### New features diff --git a/azbfs/url_directory.go b/azbfs/url_directory.go index 997e044e7..1c43f4e8f 100644 --- a/azbfs/url_directory.go +++ b/azbfs/url_directory.go @@ -28,6 +28,10 @@ func NewDirectoryURL(url url.URL, p pipeline.Pipeline) DirectoryURL { return DirectoryURL{directoryClient: directoryClient, filesystem: urlParts.FileSystemName, pathParameter: urlParts.DirectoryOrFilePath} } +func (d DirectoryURL) IsFileSystemRoot() bool { + return d.pathParameter == "" +} + // URL returns the URL endpoint used by the DirectoryURL object. func (d DirectoryURL) URL() url.URL { return d.directoryClient.URL() @@ -64,11 +68,22 @@ func (d DirectoryURL) NewDirectoryURL(dirName string) DirectoryURL { } // Create creates a new directory within a File System -func (d DirectoryURL) Create(ctx context.Context) (*DirectoryCreateResponse, error) { +func (d DirectoryURL) Create(ctx context.Context, recreateIfExists bool) (*DirectoryCreateResponse, error) { + var ifNoneMatch *string + if recreateIfExists { + ifNoneMatch = nil // the default ADLS Gen2 behavior, see https://docs.microsoft.com/en-us/rest/api/storageservices/datalakestoragegen2/path/create + } else { + star := "*" // see https://docs.microsoft.com/en-us/rest/api/storageservices/datalakestoragegen2/path/create + ifNoneMatch = &star + } + return d.doCreate(ctx, ifNoneMatch) +} + +func (d DirectoryURL) doCreate(ctx context.Context, ifNoneMatch *string) (*DirectoryCreateResponse, error) { resp, err := d.directoryClient.Create(ctx, d.filesystem, d.pathParameter, PathResourceDirectory, nil, PathRenameModeNone, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, - nil, nil, nil, nil, nil, nil, + nil, nil, nil, nil, nil, ifNoneMatch, nil, nil, nil, nil, nil, nil, nil, nil, nil) return (*DirectoryCreateResponse)(resp), err @@ -124,17 +139,17 @@ func (d DirectoryURL) ListDirectorySegment(ctx context.Context, marker *string, // It returns false if the directoryUrl is not able to get resource properties // It returns false if the url represent a file in the filesystem // TODO reconsider for SDK release -func (d DirectoryURL) IsDirectory(ctx context.Context) bool { +func (d DirectoryURL) IsDirectory(ctx context.Context) (bool, error) { grep, err := d.GetProperties(ctx) // If the error occurs while getting resource properties return false if err != nil { - return false + return false, err } // return false if the resource type is not if !strings.EqualFold(grep.XMsResourceType(), directoryResourceName) { - return false + return false, nil } - return true + return true, nil } // NewFileUrl converts the current directory Url into the NewFileUrl diff --git a/azbfs/url_file.go b/azbfs/url_file.go index 1cf6f3fad..ed4b6b9a0 100644 --- a/azbfs/url_file.go +++ b/azbfs/url_file.go @@ -53,6 +53,14 @@ func (f FileURL) WithPipeline(p pipeline.Pipeline) FileURL { return NewFileURL(f.fileClient.URL(), p) } +func (f FileURL) GetParentDir() (DirectoryURL, error) { + d, err := removeLastSectionOfPath(f.URL()) + if err != nil { + return DirectoryURL{}, err + } + return NewDirectoryURL(d, f.fileClient.p), nil +} + // Create creates a new file or replaces a file.
