MySQL to Sqlite converter
#!/bin/sh
# Converts a mysqldump file into a Sqlite 3 compatible file. It also extracts the MySQL `KEY xxxxx` from the
# CREATE block and create them in separate commands _after_ all the INSERTs.
# Awk is choosen because it's fast and portable. You can use gawk, original awk or even the lightning fast mawk.
# The mysqldump file is traversed only once.
# Usage: $ ./mysql2sqlite mysqldump-opts db-name | sqlite3 database.sqlite
# Example: $ ./mysql2sqlite --no-data -u root -pMySecretPassWord myDbase | sqlite3 database.sqlite

Ansible action plugin "include_vars_merged". Same as "include_vars" but merges hashes instead of overriding

Why?

Current version of Ansible (1.7.1) does not merge hashes in the include_vars task even if told so via hash_behaviour = merge in your ansible.cfg. ansible/ansible#9116

This action plugin will merge hashes no matter how you have configured your hash_behaviour.

How to setup:

Save include_vars_merged.py to library/plugins/action/include_vars_merged.py

Save include_vars_merged to library/custom/include_vars_merged

GitHub Flavored Asciidoc (GFA)

If you link a program with a compiler driver (clang/gcc) in a standard way (not -nostdlib), the following components are usually on the linker command line.

  • crt1.o (glibc/musl): -no-pie/-pie/-static-pie
    • crt1.o: -no-pie
    • Scrt1.o: -pie, -shared
    • rcrt1.o: -static-pie
    • gcrt1.o:
  • crti.o (glibc/musl)
  • crtbegin.o
  • crtbegin.o: -no-pie
