I wanted to compile python from source code, reading a document[1].
However I was failed to do it last time. [2]
hg clone
was failed because of the issue.
It may be because of my PC’s poor memory environment.
$ hg clone https://hg.python.org/cpython destination directory: cpython requesting all changes adding changesets adding manifests adding file changes transaction abort! rollback completed abort: stream ended unexpectedly (got 42439 bytes, expected 1852137568)
But today I found an article[3]. And finally I could download. Let me write the way here. cpython(python) has repositories for Mercurial (primary), Github(mirror). But in the git repository, the tags information is not kept. And that is not convenient to install specified version’s python.
Create empty hg environment.
$ hg init cpython $ cd cpython
Download information one by one, like a fetch.
Seeing hg log | less
after each hg pull
.
$ hg pull -r 50 https://hg.python.org/cpython $ hg pull -r 500 https://hg.python.org/cpython $ hg pull -r 5000 https://hg.python.org/cpython $ hg pull -r 50000 https://hg.python.org/cpython $ hg pull -r 100000 https://hg.python.org/cpython $ hg pull https://hg.python.org/cpython
Download files.
$ hg update
Add paths information manually
$ vi .hg/hgrc [paths] default = https://hg.python.org/cpython [ui]
$ hg paths default = https://hg.python.org/cpython
And check information finally.
$ hg heads
$ hg branches
$ hg tags
Once this operation, it’s no problem to use hg pull
.
$ hg pull pulling from https://hg.python.org/cpython searching for changes no changes found
