Stephen Atherton 2f291d8955 Bug fix in blob backup container deletion. The list/delete loop could end before deleting all of the files, but the index entry would still be deleted. Also preemptively made the same code change in listBucket() - Although it is technically correct as written it is a dangerous style because it is not obvious that the addition of a wait() call in the second 'when' block would create a bug. Consolidated deleteContainer() and deleteBucket() as they differ by only 1 line. 2018-01-29 00:32:41 -08:00
Stephen Atherton 93b34a945f Major usability and performance improvements to backup management. Backup descriptions now calculate and display timestamps using TimeKeeper data (if given a cluster) and restorability of snapshots. Expire now requires a --force option to leave a backup unrestorable or unrestorable after a given point in time, specified by version or timestamp. BackupContainerFilesystem now maintains metadata on key version boundaries in order to avoid large list operations for describe and expire operations. Blob parallel recursive list operations can now take a path (aka prefix) filter function. New describe and expire options are available in fdbbackup. 2018-01-17 04:09:43 -08:00
Stephen Atherton 96cb06cbc7 Bug fixes. Fdbbackup delete was broken. Blobstore backup container deletion would do too much listing before deletions began due to list operations queueing up ahead of and starving the delete operations. Created new knob and blob endpoint limit for concurrent list operations to fix this. Increased blob request timeout default because some requests were taking longer. Crash fixes in blobstore doRequest() which wasn't checking that response object is valid before using it in error conditions. Filesystem-like backup container class (covering blobstore and local dirs) now ignores unrecognized filenames for describe() and expire() operations. 2018-01-05 23:06:39 -08:00
Stephen Atherton 78430425e8 Blob bucket listings will now use parallel recursive requests on CommonPrefixes, up to a max depth, if a delimiter is provided. 2018-01-02 23:17:52 -08:00
Stephen Atherton e3aee45a74 Backup tools and agent now accept blob account credentials via files containing JSON which are specified using command line arguments and/or an environment variable. Improved fdbbackup help, clarifying which options are for which operations. Fdbbackup operations which do not need to use a database no longer require a cluster file parameter. Added eat() commands to StringRef for incrementally tokenizing strings using separator strings. 2017-12-21 01:58:15 -08:00
Stephen Atherton 1e643239f9 Improvement in blob connnection reuse, oldest connnections in pool are now used first. 2017-11-30 12:57:29 -08:00
Stephen Atherton 3dfaf13b67 IBackupContainer has been rewritten to be a logical interface for storing, reading, deleting, expiring, and querying backup data. The details of how the data is organized or stored is now hidden from users of the interface. Both the local and blobstore containers have been rewritten, the key changes being a multi level directory structure and no more use of temporary files or pseudo-symlinks in the blob store implementation. This refactor has a large impact radius as the previous backup container was just a thin wrapper that presented a single level list of files and offered no methods for managing or interpreting the file structure so all of that logic was spread around other places in the code base. This made moving to the new blob store schema very messy, and without this refactor further changes in the future would only be worse.
Several backup tasks have been cleaned up / simplified because they no longer need to manage the ‘raw’ structure of the backup.  The addition of IBackupFile and its finish() method simplified the log and range writer tasks.  Updated BlobStoreEndpoint to support now-required bucket creation and bucket listing prefix/delimiter options for finding common prefixes.  Added KeyBackedSet<T> type.  Moved JSONDoc to its own header.  Added platform::findFilesRecursively().

Still to do:  update command line tool to use new IBackupContainer interface, fix bugs in Restore startup.

Stephen Atherton ef84e52127 Improved error handling and memory usage in AsyncFileBlobStoreWrite. Writes will now fail if any upload has already failed, rather than buffering unboundedly until sync() is called to complete the file. There is also a configurable limit on how many uploads can be pending before writes will stall waiting for one to finish. 2017-10-18 05:51:30 -07:00
Stephen Atherton ebd0234514 Rewrote most error handling in BlobStoreEndpoint to fix several shortcomings in error handling and logging. The request loop now logs but rate limits all errors, and the exceptions thrown are more appropriate. HTTP 503 is now treated as retryable. Callers of BlobStoreEndpoint::doRequest() now specify which codes they consider to be successful so that more error handling can take place in the main request loop. 2017-10-18 02:52:09 -07:00
Stephen Atherton e934604f67 Added DNS resolution. Interface is INetworkConnections::resolveTCPEndpoint() to resolve, or for convenience INetworkConnections::connect(host, service) will resolve host and service (port number or service name like http) and connect to one of the addresses at random.
BlobStoreEndpoint now only accepts hostnames and an optional service, so this update is not compatible with the previous URL formats having many IP addresses.

Evan Tschannen a1f8b546e6 fix: ensure connections to blob store are evenly distributed across network addresses
added a per address limit to the number of open connections
lowered a variety of knobs to prevent us from using too much memory
