A.J. Beamon 776b289bfe Move AsyncFileBlobStore and related files to fdbclient. 2018-10-26 13:49:42 -07:00
Evan Tschannen 3f86905ea7 fix: restore did not take into account that the end version of a log file does not exist in that file. This resulted in restores done at the same version a snapshot completes to not apply the mutations at that final version. 2018-09-21 11:48:28 -07:00
Stephen Atherton cfce27b0f4 Timestamp to Version lookup using Timekeeper data was not lock aware. 2018-09-05 16:16:22 -07:00
Evan Tschannen 1c29275672 call all methods which could disable a trace event before it is initialized. In practice this means calling .error first, then .suppressFor, then all your details. 2018-08-01 14:30:57 -07:00
A.J. Beamon e5488419cc Attempt to normalize trace events:
* Detail names now all start with an uppercase character and contain no underscores. Ideally these should be head-first camel case, though that was harder to check.
* Type names have the same rules, except they allow one underscore (to support a usage pattern Context_Type). The first character after the underscore is also uppercase.
* Use seconds instead of milliseconds in details.

Added a check when events are logged in simulation that logs a message to stderr if the first two rules above aren't followed.

This probably doesn't address every instance of the above problems, but all of the events I was able to hit in simulation pass the check.

Stephen Atherton 9c901983f0 Clarity improvement, resetting backup description variable because it's no longer valid due to some of its contents being std::move'd. 2018-03-09 12:03:10 -08:00
Stephen Atherton 3a7288924a Bug fixes. During expiration, the backup container's log range metadata could be updated incorrectly if force was required and not specified or if a backup had no log begin metadata and an expire was done which covered 1 or more log file. In the latter case a backup could be left in a state where the container metadata suggests the backup has more log coverage than it actually does. 2018-03-09 11:29:23 -08:00
Stephen Atherton cb68885328 If backup expiration determines that force is required but the force parameter is not set, it will no longer throw an error unless the backup contains data from prior to the expire_before_version. 2018-03-08 11:27:15 -08:00
Alec Grieser 0bae9880f1 remove trailing whitespace from our copyright headers ; fixed formatting of python setup.py 2018-02-21 10:25:11 -08:00
Stephen Atherton d8879dc3f3 HTTP::doRequest() now reads responses in parallel with sending requests, so if the server responds before receiving all of the the request the client can stop sending the remainder of the request. For PUT requests which upload files, this prevents sending potentially several megabytes of unnecessary bytes if the server responds with an error (such as 429) before the request is completely sent. Updated the backup container unit test to use more parallelism in order to test this new behavior. 2018-02-07 10:38:31 -08:00
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 83409fb067 Bug fix, versionFolderString() was not reducing the precision of the number in the output string. Not technically a 'bug' as the scheme will still work but produces an overly deep and sparse folder structure. 2018-01-24 10:29:37 -08:00
Stephen Atherton 40d38880fe Changed version-based folder naming scheme to something simpler, a fixed width 0-padded 19 digit number (the longest a Version can be) with /'s inserted to limit the size of each folder level. Comparisons using these folder names ignore the /'s so any future change to the splitting scheme would still be compatible with the current listing/reading logic. 2018-01-23 15:02:15 -08:00
Stephen Atherton 7db7a51440 Changes to backup folder structure in BackupContainerBlobStore at the top level inside the backup bucket. All data files now live under data/<backup_name> and there is an 'index' at backups/<backup_name> which indicates what backups exist. Backup names can now contain '/' characters. 2018-01-23 11:46:16 -08:00
Stephen Atherton 7f0b7311b9 Corrected function name to timeKeeperVersionFromDatetime(). 'Fdbbackup expire' now allows an expire_before version of 0 if explicitly passed by version or by timestamp. 2018-01-23 00:19:51 -08:00
Stephen Atherton 51a1bd9327 Timekeeper lookup improvements, moved both function declartions to BackupContainer.h. VersionFromEpochs() now uses versions/sec to adjust the lookup result to improve accuracy. Conversions in both directions look for the latest record less than the target conversion value, but failing that they will now fall back on any available data point and adjust from there using versions/sec. 2018-01-22 23:57:01 -08:00
Stephen Atherton f086ba9d9d Improved version to timestamp lookup - if there are no older versioned records in the database then the next available record, if any, will be used to calculate a result. 2018-01-22 22:47:57 -08:00
Stephen Atherton b6dd06d945 Bug fix in version to timestamp conversion. 2018-01-18 02:54:12 -08:00
Stephen Atherton 307e04c0ad Updated backup container unit test to match new safer behavior of expireData(). Rewrote BackupContainerLocalDirectory::deleteContainer() to actually delete the whole directory but only if it appears to be a backup with either log or snapshot data. 2018-01-18 00:36:28 -08:00
Stephen Atherton cdd1e784dc Added yields to writing backup snapshot manifests to avoid slow tasks. 2018-01-17 13:28:56 -08:00
Stephen Atherton f6f0816bc1 Merge branch 'release-5.1' of github.com:apple/foundationdb into release-5.1 2018-01-17 12:12:12 -08:00
Stephen Atherton 8fece71662 Bug fix in backup metadata handling if logEnd becomes less than logBegin, which can happen if an expire is done without logEnd being updated. 2018-01-17 12:12:04 -08:00
Stephen Atherton d7f8fe218a Bug fix, resolving versions to timestamps for use in backup descriptions did not work on a locked database. Added some trace events to AtomicRestore to show progress. 2018-01-17 12:03:19 -08:00
A.J. Beamon 4bfbdbf454 Extract getLocalTime to platform.cpp 2018-01-17 11:35:34 -08:00
Stephen Atherton a6fc30209e Compile fix on windows, localtime_r is not available there. 2018-01-17 09:55:25 -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 96c479dc71 Rare bug fix. It turns out that backup log files must be written with unique names, otherwise a re-written >1 block log file overwritten after a restore has begun could read some blocks from before the rewrite and some blocks after, but due to random content ordering this would be incorrect and produce a corrupt restore. This bug is very rare because restore would detect an error unless the rewritten log file has exactly same size as the original file, but this is unlikely because the random content order affects block padding and therefore usable content bytes per block. 2018-01-02 23:38:01 -08:00
Stephen Atherton 371dee70e6 Improved backup folder structure to be shallower but spread files more uniformly and make each folder's entries lexically sort into version order regardless of numeric length. Improved backup container test to use a random version multiplier on the file versions created in order to test a wide range of versioned folder paths. 2018-01-02 23:22:35 -08:00
Stephen Atherton f2524ffd33 AsyncFileBlobStoreWrite was prohibiting the writing of 0-byte files. Improved HTTP verbose logging to stdout. Added writing a 0-byte file to BackupContainer unit test. Added backup log and snapshot sizes to backup description. 2017-12-21 21:15:26 -08:00
Evan Tschannen 95b502e1d7 fix: we did not restore to the target version in all cases 2017-12-21 14:11:44 -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
Evan Tschannen c51de3bb88 fixed windows compile issues 2017-12-20 13:48:31 -08:00
Stephen Atherton c1958b335a Compile fix on windows, can't access protected parent class member from static function, apparently. 2017-12-20 12:13:25 -08:00
Stephen Atherton 47a9a7ab0e Finished backup container discovery / listing via base URL. 2017-12-12 17:44:03 -08:00
Stephen Atherton d3b4a81ed0 Blobstore connection details in unit tests now come from environment variables. 2017-12-06 14:38:45 -08:00
Balachandar Namasivayam 1f949240f5 Make fdbbackup s3 compatible.
s3 sends response in XML.  FDB backup expects json response. Added a new libraray xml2json to convert xml to json.

Stephen Atherton 6695c9e6a2 Bug fixes and improvements to error handling and trace events. The most serious bug was that restore would start at the wrong version, possibly skipping early log and range files. 2017-11-25 00:46:16 -08:00
Stephen Atherton 9354a8cbb4 Added new backup container method to list everything in a backup. 2017-11-19 04:28:22 -08:00
Stephen Atherton 07c19098fe Improved backup container unit test, added file reading / verification, more data, and a series of expirations and validating the expected result. Then fixed the bugs that this new testing discovered. 2017-11-16 16:19:56 -08:00
Stephen Atherton f105204aca Shifted version distribution over folders. 2017-11-15 23:13:04 -08:00
Stephen Atherton ab0017f023 TaskBucket’s TaskFunc interface now has an optional handleError() which is called on any task that throws an error from execute() or finish(). Restore and Backup tasks use this to ensure that any errors that occur are placed in the backup or restore config’s lastError property. Bug fixes in log and range file encodings. 2017-11-15 13:33:09 -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.
