This patch makes replication crash-safe with the new binlog implementation, even when --innodb-flush-log-at-trx-commit=0|2. The point is to not send any binlog events to the slave until they have become durable on master, thus avoiding that a slave may replicate a transaction that is lost during master recovery, diverging the slave from the master. Keep track of which point in the binlog has been durably synced to disk (meaning the corresponding LSN has been durably synced to disk in the InnoDB redo log). Each write to the binlog inserts an entry with offset and corresponding LSN in a FIFO. Dump threads will first read only up to the durable point in the binlog. A dump thread will then check the LSN fifo, and do an InnoDB redo log sync if anything is pending. Then the FIFO is emptied of any LSNs that have now become durable, and the durable point in the binlog is updated and reading the binlog can continue.

A quicker way for adding new language translations to the errmsg-utf8.txt file
Summary
To generate a new language translation of MariaDB use the following pull request (PR) as a template for your work:
You will notice as part of your translation work, you will have to add your language translations to the file sql/share/errmsg-utf8.txt which is found in the current directory. This file is long with many sections which can make the translation work tedious. In this README, we explain a procedure and provide a script insert_translations_into_errmsg.py that cuts down the amount of tedium in accomplishing the task.
Procedure
-
Start by grepping out all the english translations from errmsg-utf8.txt using the following grep command, and redirecting the output to a file:
grep -P "^\s*eng\s" errmsg-utf8.txt > all_english_text_in_errmsg-utf8.txt
-
Next use Google translate to obtain a translation of this file. Google translate provides the ability to upload whole files for translation. For example, this technique was used to obtain Swahili translations which yielded a file with output similar to the below (output is truncated for clarity):
sw "hashchk" sw "isamchk" sw "LA" sw "NDIYO" sw "Haiwezi kuunda faili '% -.200s' (kosa: %M)" sw "Haiwezi kuunda jedwali %
s.%s (kosa: %M)" sw "Haiwezi kuunda hifadhidata '% -.192s' (kosa: %M)" sw "Haiwezi kuunda hifadhidata '% -.192s'; hifadhidata ipo"
Note that Google translate removes the leading whitespace in the translation file it generates. DO NOT add that leading whitespace back!
-
Give the translated file an appropriate name (e.g.
all_swahili_text_in_errmsg-utf8.txt) and store it in the same directory witherrmsg-utf8.txtandall_english_text_in_errmsg-utf8.txt. These 3 files will be used by the script insert_translations_into_errmsg.py. -
Proof check the auto-translations in the file you downloaded from Google translate. Note that Google might ommit formating information that will cause the compilation of MariaDB to fail, so pay attention to these.
-
Reintegrate these translations into the errmsg-utf8.txt by running the insert_translations_into_errmsg.py script as follows:
chmod ugo+x insert_translations_into_errmsg.py # Make the script executable if it is not.
./insert_translations_into_errmsg.py <errmsg-utf8.txt file>
For example, for the swahili translation, we ran the following:
./insert_translations_into_errmsg.py errmsg-utf8.txt all_english_text_in_errmsg-utf8.txt all_swahili_text_in_errmsg-utf8.txt
The script uses the
errmsg-utf8.txtfile and the grepped english file to keep track of each new translation. It then creates a file in the same directory aserrmsg-utf8.txtwith the nameerrmsg-utf8-with-new-language.txt. -
Check that the reintegration of the new translations into
errmsg-utf8-with-new-language.txtwent OK, and if it did, renameerrmsg-utf8-with-new-language.txttoerrmsg-utf8.txt:mv errmsg-utf8-with-new-language.txt errmsg-utf8.txt
-
In the header of errmsg-utf8.txt make sure to add your language long form to short form mapping. E.g. for Swahili, add:
swahili=sw
