* Add save file locally feature to fdbdecode
* Fix use-after-free in fdbdecode
This only happens in clang, though.
* Minor refactor for fdbdecode
* Fix a small memory leak in fdbdecode
* Unify flags implementation and change help text in backup.actor.cpp
Description
Testing
* Keep LOG_GROUP unchanged
Description
Testing
* Transfer the hyphens to underscores for internal options and user's input, EXCEPT leading hyphens
Description
Testing
* Use a deep copy of the user's input flag to do the match
Description
Testing
* Convert the _ to - in Option arrays of backup.actor.cpp
Description
Testing
* Transter _ to - for files:
TLSConfig.actor.h, fdbcli.actor.cpp, fdbserver.actor.cpp, FileConverter.h, FileConverter.cpp
Description
Testing
* Change another way to unify flag: using SO_O_ICASE_HYPHEN_AND_UNDERSCORE to determine whether we do the conversion in function IsEqual
Description
Testing
* Change the config command's name from SO_O_ICASE_HYPHEN_AND_UNDERSCORE to SO_O_HYPHEN_TO_UNDERSCORE
Description
Testing
* Update the comment for the SO_O_HYPHEN_TO_UNDERSCORE
Description
Testing
* Fix left underscore in SOption arrays
Description
Testing
* Convert _ to - in several files for commands
Description
Testing
* Make the FDBService and fdbmonitor backward compatible
Description
Testing
* Fix bugs about pointers
Description
Testing
* Check underscore and hyphen at the same time for --knob_, --localily_ and --test_
And fix bugs in fdbmonitor and FDBService
Description
Testing
* Simplify the function in fdbmonitor and FDBService about retrieving arguments.
And fix some documents in masterserver.actor.cpp
Description
Testing
* Convert _ to - for knob in the setKnob functions
Description
Testing
* Convert - to _ in the setKnob functions
Description
Since key in the knob related maps only contain _
Testing

In the old mutation logs, a version's mutations are serialized as a buffer.
Then the buffer is split into smaller chunks, e.g., 10000 bytes each. When
writting chunks to the final mutation log file, these chunks can be flushed
out of order. For instance, the (version, chunck_part) can be in the order of
(3, 0), (4, 0), (3, 1). As a result, the decoder must read forward to find all
chunks of data for a version.
Another complication is that the files are organized into blocks, where (3, 1)
can be in a subsequent block. This change checks the value size for each
version, if the size is smaller than the right size, the decoder will look
for the missing chucks in the next block.
fdbconvert is intended to convert new backup files which are tagged mutation
logs to old backup format. The actual conversion is not included in this commit
and will be added in future commits.
Note that the BackupContainer needs to be updated to support new backup files,
which is also not included in this commit.
