[redmine] repository trouble shooting

 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);
DELETE FROM changesets WHERE changesets.repository_id = 415;

4) If timeout occurs during delete query, do follows and do it again.
  OPTIMIZE TABLE `redmine_333`.`changes`


5) If you want to fetch manually, do follows on redmine home directory and look for what errors occur.
  rails runner "Repository.fetch_changesets" -e production
   ( the older version: ruby script/runner "Repository.fetch_changesets" -e production )

sanitize on in CMakeLists.txt

1. CMakeLists.txt set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -fsanitize=address") add_compile_options(-fsanitize=address) If a subdir is set with add_subdirectory and a module that does not support sanitize is imported from the path and needs to be removed, add -fno-sanitize=address to add_compile_options in CMakeLists.txt of the subdir to remove it. Basically, if you enable sanitize, sanitize will adjust ulimit's core to 0, so core will not occur. You can do this by putting the following part as an environment variable. (Below is the part you put in systemd's service) 2. service file in systemd [Service] LimitCORE=infinity Environment="ASAN_OPTIONS=handle_segv=0:handle_abort=1:abort_on_error=1:disable_coredump=0"
