The program threads-memory.c
(included below) starts 100 threads, allocates 1
MB of memory in each, and then pauses. How much memory is it using?
Let's find out by running it:
$ gcc -pthread threads-memory.c -o threads-memory
#!/usr/bin/env bash | |
# Checked with ShellCheck (https://www.shellcheck.net/) | |
# Shell setup | |
# =========== | |
# Bash options for strict error checking. | |
set -o errexit -o errtrace -o pipefail -o nounset | |
shopt -s inherit_errexit 2>/dev/null || true |
# Run as root or add `sudo` where needed. | |
# General tools. | |
apt-get update | |
apt-get install --no-install-recommends git ca-certificates build-essential devscripts dpkg-dev | |

# Step 1: Obtain a list of our personal hosts. | |
# Export from Bitwarden, LastPass, 1Password, or similar: | |
my_passwords.txt | |
# Next commands will assume the LastPass export format, which is CSV with the URL in the first field: | |
# url,username,password,[... more fields] |
# Run command: | |
# | |
# $ python3 HttpPostServer.py | |
# | |
# Test POST with a complete file: | |
# | |
# $ curl --data-binary "@small_file.bin" "http://127.0.0.1:8080/small.bin" | |

# Test POSTing a file progressively (chunked mode): | |
