# Notes on maintaining/upgrading
## Upgrading texlive.bin
## Upgrading `texlive.bin`
texlive contains a few binaries, defined in bin.nix and released once a year.
`texlive` contains a few binaries, defined in `bin.nix` and released once a year.
In order to reduce closure size for users who just need a few of them, we split it into
packages such as core, core-big, xvdi, etc. This requires making assumptions
packages such as `core`, `core-big`, `xdvi`, etc. This requires making assumptions
about dependencies between the projects that may change between releases; if
you upgrade you may have to do some work here.
## Updating the package set
texlive contains several thousand packages from CTAN, defined in pkgs.nix.
`texlive` contains several thousand packages from CTAN, defined in `tlpdb.nix`.
The CTAN mirrors are not version-controlled and continuously moving,
with more than 100 updates per month.
To create a consistent and reproducible package set in nixpkgs, we snapshot CTAN
and generate nix expressions for all packages in texlive at that point.
We mirror CTAN sources of this snapshot on community-operated servers and on IPFS.
To upgrade the package snapshot, follow this process:
### Snapshot sources and texlive package database
Mirror the current CTAN archive to our mirror(s) and IPFS (URLs in `default.nix`).
See https://tug.org/texlive/acquire-mirror.html for instructions.
To create a consistent and reproducible package set in nixpkgs, we generate nix
expressions for all packages in TeX Live at a certain day.
To upgrade the package snapshot, follow this process.
### Upgrade package information from texlive package database
First, edit `default.nix` as follows.
If upgrading to a daily snapshot:
- change `snapshot.year`, `snapshot.month`, `snapshot.day`;
- ensure `urlPrefixes` uses the https://texlive.info/tlnet-archive mirror;
- ensure `texlive.extraVersion` uses the `snapshot` info.
If upgrading to a final release:
- upgrade `texlive.bin` first;
- ensure `urlPrefixes` uses the historic mirrors;
- ensure `texlive.extraVersion` is `"-final"`.
Then upgrade `tlpdb.hash` to match the new hash of `texlive.tlpdb.xz` and run
Update `version` in `default.nix` with the day of the new snapshot, the new TeX
Live year, and the final status of the snapshot. Then update
`texlive.tlpdbxz.hash` to match the new hash of `texlive.tlpdb.xz` and run
```bash
nix-build ../../../../.. -A texlive.tlpdb-nix --no-out-link
nix-build ../../../../.. -A texlive.tlpdb.nix --no-out-link
```
This will download the daily snapshot of the CTAN package database
`texlive.tlpdb.xz` and extract the relevant package info (including version
numbers and sha512 hashes) for the selected upstream distribution. Then replace
`tlpdb.nix` with the generated file.
This will download either the daily or the final snapshot of the TeX Live
package database `texlive.tlpdb.xz` and extract the relevant package info
(including version numbers and sha512 hashes) for the selected upstream
distribution.
The test `pkgs.tests.texlive.tlpdb-nix` verifies that the file `tlpdb.nix`
Finally, replace `tlpdb.nix` with the generated file. Note that if the
`version` info does not match the metadata of `tlpdb.nix` (as found in the
`00texlive.config` package), TeX Live packages will not evaluate.
The test `pkgs.tests.texlive.tlpdbNix` verifies that the file `tlpdb.nix`
in Nixpkgs matches the one that generated from `texlive.tlpdb.xz`.
