67 00ced238 2021-09-24 thomas $ make tests
70 1317cd3a 2022-03-08 thomas NOTE: For Linux, you must have the jot(1) command which is typically in the

74 00ced238 2021-09-24 thomas NOTE: THIS ONLY WORKS AFTER `make install` DUE TO HOW PATHS TO LIBEXEC

86 00ced238 2021-09-24 thomas BRANCHES + SUBMITTING PATCHES
87 00ced238 2021-09-24 thomas =============================
89 00ced238 2021-09-24 thomas `got-portable` has two key branches:
91 00ced238 2021-09-24 thomas * `main` which tracks got upstream untainted.
92 2f4dd2c2 2021-09-27 thomas * `linux` which provides the portable version of GoT based from code on `main`
94 00ced238 2021-09-24 thomas Patches for portable code fixes should be based from the `linux` branch and
95 00ced238 2021-09-24 thomas sent to the mailing list for review [2] or sent to me directly (see CONTACT).
97 61702ba6 2022-07-19 thomas Portable-specific patches should have a shortlog in the form of:
100 61702ba6 2022-07-19 thomas portable: AREA: description
103 61702ba6 2022-07-19 thomas Where `AREA` relates to the change in question (for example, `regress`,
104 61702ba6 2022-07-19 thomas `libexec`, etc). In some cases, this can be omitted if it's a generic change.
106 61702ba6 2022-07-19 thomas This helps to delineate `-portable` changes from upstream `got`.
108 00ced238 2021-09-24 thomas The read-only Github repository also runs CI checks using Cirrus-CI on Linux
109 00ced238 2021-09-24 thomas and FreeBSD.
111 585fb430 2022-07-21 thomas SYNCING UPSTREAM CHANGES WITH PORTABLE
112 585fb430 2022-07-21 thomas ======================================
114 585fb430 2022-07-21 thomas The `-portable` GoT repository uses the following workflow:
117 585fb430 2022-07-21 thomas Github (gh) GoT (upstream)
123 585fb430 2022-07-21 thomas +--------> GoT-portable <------+
127 585fb430 2022-07-21 thomas Here, `got-portable` is a clone of the `-portable` repository, locally on
128 585fb430 2022-07-21 thomas disk. There are two remotes set up within that repository, via `git-remote`:
130 585fb430 2022-07-21 thomas * `upstream` -- which points to the official GoT repository;
131 585fb430 2022-07-21 thomas * `gh` -- which points to the mirrored `-portable` repository so that CI can
132 585fb430 2022-07-21 thomas be run for cross-platform/test purposes [3]
133 585fb430 2022-07-21 thomas * `origin` -- our cloned copy from `-portable`
135 585fb430 2022-07-21 thomas Within the `-portable` repository are two key branches (there may be other
136 585fb430 2022-07-21 thomas topic branches which represent on-going work):
138 585fb430 2022-07-21 thomas * `main` -- this is the branch that tracks (without modification) those
139 585fb430 2022-07-21 thomas changes from `upstream`. This branch is continually reset to
140 585fb430 2022-07-21 thomas `upstream/main` whenever changes occur.
142 585fb430 2022-07-21 thomas * `linux` -- this is the *default* branch of the `-portable` repository which
143 585fb430 2022-07-21 thomas contains portable-specific changes to make `GoT` compile across different
146 585fb430 2022-07-21 thomas When updating `-portable` from upstream changes, the following actions happen:
148 585fb430 2022-07-21 thomas 1. Changes from `upstream` are fetched. If there are no new changes, there's
149 585fb430 2022-07-21 thomas nothing else to do.
150 585fb430 2022-07-21 thomas 2. Changes from `gh` are fetch so that the result can be pushed out to `gh`.
151 585fb430 2022-07-21 thomas 3. The difference between the local copy of `main` and `origin/main` is used
152 585fb430 2022-07-21 thomas to represent the set of commits which have *NOT* yet been merged to
153 585fb430 2022-07-21 thomas `-portable`.
154 585fb430 2022-07-21 thomas 4. A topic-branch called `syncup` is created from the HEAD of the `linux`
155 585fb430 2022-07-21 thomas branch to hold the to-be-cherry-picked commits from step 3.
156 585fb430 2022-07-21 thomas 5. These commits are then cherry-picked to the `syncup` branch.
157 585fb430 2022-07-21 thomas 6. If there's any conflicts, they must be resolved.
158 585fb430 2022-07-21 thomas 7. Once done, a sanity build is done in-situ to check there's nothing amiss.
159 585fb430 2022-07-21 thomas 8. If that succeeds, the `syncup` branch is merged to `linux` and pushed to
160 585fb430 2022-07-21 thomas `gh` for verification against CI.
161 585fb430 2022-07-21 thomas 9. If that fails, fixes continue and pushed up to `gh` as required.
162 585fb430 2022-07-21 thomas 10. Once happy, both the `main` and `linux` branches can be merged to `origin`.
164 585fb430 2022-07-21 thomas These steps are encapsulated in a script within `-portable`. [Link](../maintscripts/sync-upstream.sh)
166 ce0dfd3b 2022-07-21 thomas RELEASING A NEW VERSION
167 ce0dfd3b 2022-07-21 thomas =======================
169 ce0dfd3b 2022-07-21 thomas Release for `-portable` try and align as close to upstream GoT as much as
170 ce0dfd3b 2022-07-21 thomas possible, even on the same day where that can happen. That being said,
171 ce0dfd3b 2022-07-21 thomas sometimes a release of `-portable` might happen outside of that cadence, where
172 ce0dfd3b 2022-07-21 thomas a `-portable`-specific issue needs addressing, for example.
174 ce0dfd3b 2022-07-21 thomas Before creating a new release, check the version of GoT as found in
175 598139dd 2022-07-22 thomas `util/got-portable-ver.sh` -- as `GOT_PORTABLE_VER`:
178 598139dd 2022-07-22 thomas GOT_PORTABLE_VER=0.75
182 ce0dfd3b 2022-07-21 thomas Here, the *to be released* version of `got-portable` will be `0.75`.
183 ce0dfd3b 2022-07-21 thomas Typically, this version is incremented directly after a release, such that
184 ce0dfd3b 2022-07-21 thomas there's no need to change this value. The only exception would be if there
185 ce0dfd3b 2022-07-21 thomas were an out-of-band release to `-portable`. In such cases, that would take
186 ce0dfd3b 2022-07-21 thomas the form:
192 ce0dfd3b 2022-07-21 thomas Where the suffix of `a`, `b`, etc., can be used to denote any sub-releases
193 ce0dfd3b 2022-07-21 thomas from the `0.75` version.
195 05345ace 2022-09-10 thomas The variable `GOT_RELEASE` needs be changed to `yes` so that the
196 05345ace 2022-09-10 thomas GOT_PORTABLE_VER is asserted correctly.
198 ce0dfd3b 2022-07-21 thomas Once the version is verified, the following should be run from the `linux`
199 ce0dfd3b 2022-07-21 thomas branch -- and the repository should not have any outstanding modifications to
200 ce0dfd3b 2022-07-21 thomas the source:
203 ce0dfd3b 2022-07-21 thomas make clean ; ./autogen && ./configure && make distcheck
206 ce0dfd3b 2022-07-21 thomas If this succeeds, the tarball is in the CWD, as: `got-portable-VERSION.tar.gz`
208 ce0dfd3b 2022-07-21 thomas This can then be copied to the `got-www` repository and uploaded, along with
209 ce0dfd3b 2022-07-21 thomas changing a couple of HTML pages therein to represent the new released version.
210 ce0dfd3b 2022-07-21 thomas Additionally, the CHANGELOG file can be copied to the `got-www` and committed.
215 00ced238 2021-09-24 thomas This port is incomplete in that only got(1) and tog(1) have been ported.
216 00ced238 2021-09-24 thomas gotweb has yet to be ported.
218 00ced238 2021-09-24 thomas configure.ac should start defining AC_ENABLE arguments to allow for
219 00ced238 2021-09-24 thomas finer-grained control of where to search for includes/libraries, etc.
