Ryan Gonzalez 8ab8398c50 Use github.com/saracen/walker for file walk operations 
In some local tests w/ a slowed down filesystem, this massively cut down
on the time to clean up a repository by ~3x, bringing a total 'publish
update' time from ~16s to ~13s.

Downloaded packages

SHA-256

For each uploaded Debian package a SHA-256 checksum is computed. This checksum is used to create a file tree where each package will reside, with following hierarchy.

Directory and sub-directories structure

  • 1st and 2nd characters of SHA-256 checksum as sub-directory of rootDir/pool directory.
  • 3rd and 4th characters of SHA-256 checksum as sub-directory of the former

ex:

sha256sum 476e0cdac6bc757dd2b78bacc1325323b09c45ecb41d4562deec2a1c7c148405 my-package_1.2.3_all.deb

${rootDir}/pool # rootDir defined in aptly.conf
└── 47
    └── 6e

Filename

The following items are concatenated to form the filename under which package is stored.

  • 5th to the 31st characters of SHA-256 checksum
  • "_" (undescore)
  • filename of uploaded Debian as defined in Debian package file names

ex:

sha256sum 476e0cdac6bc757dd2b78bacc1325323b09c45ecb41d4562deec2a1c7c148405 my-package_1.2.3_all.deb

 0cdac6bc757dd2b78bacc13253_my-package_1.2.3_all.deb

MD5

For each uploaded Debian package a MD5 checksum is computed. This checksum is used to create a file tree where each package will reside, with following hierarchy

Note: MD5 is only legacy layout. Its support is limited to 'read' files from the pool, it never puts files this way for new package files.

Directory and sub-directories structure

  • 1st and 2nd characters of MD5 checksum as sub-directory name of rootDir/pool directory
  • 3rd and 4th characters of MD5 chacksum as sub-directory name of the former

ex:

md5sum feea3c0c3e823615bf2d417b052a96b4 my-package_1.2.3_all.deb

${rootDir}/pool # rootDir defined in aptly.conf
└── fe
    └── ea

Filename

Uploaded Debian is stored as-is and not renamed.

Example

${rootDir}/pool # rootDir defined in aptly.conf
