8 GoCheese is Python private package repository and caching proxy.
10 It serves two purposes:
13 @item proxying and caching of missing packages from upstream
14 @url{https://pypi.org/, PyPI}, conforming to
15 @url{https://www.python.org/dev/peps/pep-0503/, PEP-0503}
16 (Simple Repository API)
17 @item hosting of private locally uploaded packages, conforming to
18 @url{https://warehouse.pypa.io/api-reference/legacy/, Warehouse Legacy API}
21 Initially it was created as a fork of
22 @url{https://github.com/c4s4/cheeseshop, cheeseshop},
23 but nearly all the code was rewritten. It has huge differences:
26 @item proxying and caching of missing packages, including GPG signatures
27 @item @url{https://pythonwheels.com/, Wheel} uploading support
28 @item atomic packages store on filesystem
29 @item SHA256-checksummed packages: storing checksums, giving them back,
30 verifying stored files integrity, verifying checksum of uploaded
32 @item graceful HTTP-server shutdown
33 @item no YAML configuration, just command-line arguments
34 @item no package overwriting ability (as PyPI does)
37 Also it contains @file{pyshop2packages.sh} migration script for
38 converting @url{https://pypi.org/project/pyshop/, Pyshop} database into
39 GoCheese one, including private packages.
41 GoCheese is free software, licenced under
42 @url{https://www.gnu.org/licenses/gpl-3.0.html, GNU GPLv3}:
43 see the file COPYING for copying conditions.
47 * Password authentication: Passwords.
49 * Storage format: Storage.
55 To use it for download purposes, just configure your @file{pip.conf}:
59 index-url = http://gocheese.host:8080/simple/
62 @option{-refresh} URL behaves the same way as @option{-simple} one, but
63 is always refreshes package versions from PyPI when listing it. You can
64 use it to forcefully update known package versions.
66 You can upload packages to it with
67 @url{https://pypi.org/project/twine/, twine}:
71 --repository-url http://gocheese.host:8080/simple/ \
73 --password foo dist/tarball.tar.gz
76 If @command{twine} sends SHA256 checksum in the request, then uploaded
77 file is checked against it.
79 @option{-gpgupdate} is useful mainly for migrated from Pyshop
80 repositories. It forces GPG signature files downloading for all existing
84 @unnumbered Password authentication
86 Password authentication is required for packages uploading.
87 You have to store your authentication data in @option{-passwd} file in
91 username:hashed-password
94 Empty lines and having @verb{|#|} at the beginning are skipped.
96 Supported hashing algorithms are:
100 @item @url{https://www.argon2i.com/, Argon2i} (recommended one!)
101 To get Argon2i hashed-password you can use any of following tools:
103 @item @url{https://github.com/balakhonova/argon2i,
104 go get github.com/balakhonova/argon2i} (Go)
105 @item @url{https://github.com/p-h-c/phc-winner-argon2} (C)
107 Example user @code{foo} with password @code{bar} can have the
108 following password file entry:
111 foo:$argon2i$v=19$m=32768,t=3,p=4$OGU5MTM3YjVlYzQwZjhkZA$rVn53v6Ckpf7WH0676ZQLr9Hbm6VH3YnL6I9ONJcIIU
115 You can use your operating system tools:
119 $ echo -n "password" | sha256
121 # GNU/Linux-based systems
122 $ echo -n "password" | sha256sum
124 Example user @code{foo} with password @code{bar} will have the
125 following password file entry:
128 foo:$sha256$fcde2b2edba56bf408601fb721fe9b5c338d10ee429ea04fae5511b68fbf8fb9
133 You can refresh passwords by sending @code{SIGHUP} signal to the working daemon:
136 $ pkill -HUP gocheese
137 $ kill -HUP `pidof gocheese`
140 Before refreshing it's recommended to check @option{-passwd} file with
141 @option{-passwd-check} option to prevent daemon failure.
144 @unnumbered TLS support
146 You can enable TLS support by specifying PEM-encoded X.509 certificate
147 and private key files. Go's TLS implementation supports TLS 1.3, HTTP/2
148 negotiation, Keep-Alives, modern ciphersuites and ECC.
150 For example generate some self-signed certificate using GnuTLS toolset:
153 $ certtool --generate-privkey --ecc --outfile prv.pem
154 $ cert_template=`mktemp`
155 $ echo cn=gocheese.host > $cert_template
157 --generate-self-signed \
158 --load-privkey=prv.pem \
159 --template $cert_template \
162 $ gocheese -tls-cert cert.pem -tls-key prv.pem [...]
166 @unnumbered Storage format
168 Root directory has the following hierarchy:
173 | +- public-package-0.1.tar.gz.sha256
174 | +- public-package-0.2.tar.gz
175 | +- public-package-0.2.tar.gz.sha256
178 | +- private-package-0.1.tar.gz
179 | +- private-package-0.1.tar.gz.sha256
183 Each directory is a package name. When you try to list non existent
184 directory contents (you are downloading package you have not seen
185 before), then GoCheese will download information about package's
186 versions with checksums and write them in corresponding @file{.sha256}
187 files. However no package package tarball is downloaded.
189 When you request for particular package version, then its tarball is
190 downloaded and verified against the checksum. For example in the root
191 directory above we have downloaded only @file{public-package-0.2}.
193 Private packages contain @file{.private} file, indicating that it must
194 not be asked in PyPI if required version is missing. You have to create
