When I download a zip from github, what is the hex string at the end of the file name represent?

If I go to https://github.com/wesm/pandas and click the "Download" button to download a zip (or tar) archive of the repository, the file name of the archive I get is:

wesm-pandas-0.3.0-93-g1d40e65.zip

I can see that wesm-pandas repres开发者_如何学Cents the project name, and 0.3.0 represents the project version.

Does 93 represent the number of commits on that branch?

What does g1d40e65 represent?

After the username and the project, the filename is obtained from the output of:

git describe --always

Example from the man page:

[torvalds@g5 git]$ git describe parent

v1.0.4-14-g2414721

i.e. the current head of my "parent" branch is based on v1.0.4, but since it has a few commits on top of that, describe has added the number of additional commits ("14") and an abbreviated object name for the commit itself ("2414721") at the end.

So in your case, 93 is the number of commits since 0.3.0 and the hex after g is the sha1 of the latest commit

See https://github.com/blog/651-annotated-downloads for details on the filename format: the 1d40e65 represents an SHA of the last commit on that branch, and the 93 is the number of commits since the latest tag.
