Новая версия со сменой лицензии, существенным расширением API, добавлением функционала и внутренними переработками. В том числе, с незначительным нарушением обратной совместимости API библиотеки. Список нововведений, доработок и изменений слишком велик для размещения здесь, но вся информация есть в файле [ChangeLog](https://libmdbx.dqdkfa.ru/md__change_log.html). ``` git diff' stat: 157 files changed, 41949 insertions(+), 33741 deletions(-) Signed-off-by: Леонид Юрьев (Leonid Yuriev) <leo@yuriev.ru> ```

.SH DESCRIPTION
|
|
The
|
|
.B mdbx_load
|
|
utility reads from the standard input and loads it into the
|
|
MDBX environment
|
|
.BR dbpath .
|
|
|
|
The input to
|
|
.B mdbx_load
|
|
must be in the output format specified by the
|
|
.BR mdbx_dump (1)
|
|
utility or as specified by the
|
|
.B -T
|
|
option below.
|
|
|
|
A simple escape mechanism, where newline and backslash (\\) characters are special, is
|
|
applied to the text input. Newline characters are interpreted as record separators.
|
|
Backslash characters in the text will be interpreted in one of two ways: If the backslash
|
|
character precedes another backslash character, the pair will be interpreted as a literal
|
|
backslash. If the backslash character precedes any other character, the two characters
|
|
following the backslash will be interpreted as a hexadecimal specification of a single
|
|
character; for example, \\0a is a newline character in the ASCII character set.
|
|
|
|
For this reason, any backslash or newline characters that naturally occur in the text
|
|
input must be escaped to avoid misinterpretation by
|
|
.BR mdbx_load .
|
|
|
|
.SH OPTIONS
|
|
.TP
|
|
.BR \-V
|
|
Write the library version number to the standard output, and exit.
|
|
.TP
|
|
.BR \-q
|
|
Be quiet.
|
|
.TP
|
|
.BR \-a
|
|
Append all records in the order they appear in the input. The input is assumed to already be
|
|
in correctly sorted order and no sorting or checking for redundant values will be performed.
|
|
This option must be used to reload data that was produced by running
|
|
.B mdbx_dump
|
|
on a database that uses custom compare functions.
|
|
.TP
|
|
.BR \-f \ file
|
|
Read from the specified file instead of from the standard input.
|
|
.TP
|
|
.BR \-s \ table
|
|
Load a specific table. If no table is specified, data is loaded into the main table.
|
|
.TP
|
|
.BR \-N
|
|
Don't overwrite existing records when loading into an already existing table; just skip them.
|
|
.TP
|
|
.BR \-T
|
|
Load data from simple text files. The input must be paired lines of text, where the first
|
|
line of the pair is the key item, and the second line of the pair is its corresponding
|
|
data item.
|
|
.TP
|
|
.BR \-r
|
|
Rescure mode. Ignore errors to load corrupted DB dump.
|
|
.TP
|
|
.BR \-n
|
|
Load an MDBX database which does not use subdirectories.
|
|
This is legacy option. For now MDBX handles this automatically.
|
|
|
|
.SH DIAGNOSTICS
|
|
Exit status is zero if no errors occur.
|
|
Errors result in a non-zero exit status and
|
|
a diagnostic message being written to standard error.
