[DB_NAME]: DB-name to recovery. /dev/shm Usage: First, check your memory if you can use shm directory.   For recovery speed, I use /dev/shm/ directory. Process flow. 01. Stop DB  service mysqld stop 02. Stop web-service. (If you don't use, block DB-connection by using firewall-cmd.)  service httpd stop 03. Change DB-mode on server.cnf   set innodb_force_recovery = 5 on /etc/my.cnf.d/server.cnf 04. Start DB for recovery.  service mysqld start 05. Run DB-dump.  mysqldump -u root -p --databases [DB_NAME] > /dev/shm/[DB_NAME].sql 06. Stop DB  service mysqld stop 07. Change DB-mode on server.cnf (normal mode)  set innodb_force_recovery = 0 on /etc/my.cnf.d/server.cnf 08. Backup old DB-files. (Run follows if you necessarily need backup.)  mkdir /backup/DB_BackupTmp  mv /backup/DB/ibdata1 /backup/DB_BackupTmp  mv /backup/DB/ib_logfile0 /backup/DB_BackupTmp  mv /backup/DB/ib_logfile1 /backup/DB_BackupTmp  mv /backup/DB/[DB_NAME] /backup/DB_BackupTmp 09. Start DB  service mysqld start 10

 1) Timeout occurs when deleting repository.    Check queries by using processlist.   "show processlist;" 2) If the reason of that case is timeout, set follows.  show variables like '%timeout';  set global innodb_lock_wait_timeout=300;  set session innodb_lock_wait_timeout=300;  If you necessary, kill process to restart process.     "kill <id>;" 3) Check if you have dummy data. SELECT changesets.repository_id FROM changesets WHERE changesets.repository_id NOT IN (SELECT id from repositories) group by changesets.repository_id ; Do A or B. * A DELETE FROM changes WHERE changes.changeset_id IN (SELECT changesets.id FROM changesets WHERE changesets.repository_id NOT IN (SELECT id from repositories)); DELETE FROM changesets WHERE changesets.repository_id NOT IN (SELECT id from repositories); * or B (415 = your target repository id) DELETE FROM changes WHERE changes.changeset_id IN (SELECT changesets.id FROM changesets WHERE changesets.repository_id = 415);

Environment   raspbian: jessie   Linux phome 4.9.35-v7+ #1014 SMP Goal:   To setup Jupyter Notebook.   (needed pip3 18.1. (It required Python 3.5 but mine is 3.4.2) Conclusion:   - Python-3.6.11 : OK   - Python-3.8.3      make : OK, but pip cannot connect TLS/SSL       ( https://stackoverflow.com/questions/62827291/warning-pip-is-configured-with-locations-that-require-tls-ssl-however-the-ssl )      I think that it occurred by the difference of  openssl versions.      (But I did not to try figure out)    - Python-3.7.4 : Same problem like 3.8.3.    - Python-3.5.9 : Compile error by gcov dependency. Method:   - Download 3.6.11 source and compile.   - Type "make altinstall"   - Make file links with "update-alternatives" command.
