2020-08-17shallow.txt: document SHA-256 shallow formatMartin Ågren
Similar to recent commits, document that we list object names rather than SHA-1s. Signed-off-by: Martin Ågren <martin.agren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-04-30technical/shallow: describe why shallow cannot use replace refsJohannes Schindelin
It is tempting to do away with commit_graft altogether (in the long haul), now that grafts are deprecated. However, the shallow feature needs a couple of things that the replace refs cannot fulfill. Let's point that out in the documentation. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-04-30technical/shallow: stop referring to graftsJohannes Schindelin
Now that grafts are deprecated, we should start to assume that readers have no idea what grafts are. So it makes more sense to make the description of the "shallow" feature stand on its own.

2013-04-15The name of the hash function is "SHA-1", not "SHA1"Thomas Ackermann
Use "SHA-1" instead of "SHA1" whenever we talk about the hash function. When used as a programming symbol, we keep "SHA1". Signed-off-by: Thomas Ackermann <th.acker@arcor.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-01-11fetch: add --unshallow for turning shallow repo into complete oneNguyễn Thái Ngọc Duy
The user can do --depth=2147483647 (*) for restoring complete repo now. But it's hard to remember. Any other numbers larger than the longest commit chain in the repository would also do, but some guessing may be involved. Make easy-to-remember --unshallow an alias for --depth=2147483647. Make upload-pack recognize this special number as infinite depth. The effect is essentially the same as before, except that upload-pack is more efficient because it does not have to traverse to the bottom anymore. The chance of a user actually wanting exactly 2147483647 commits depth, not infinite, on a repository with a history that long, is probably too small to consider. The client can learn to add or subtract one commit to avoid the special treatment when that actually happens. (*) This is the largest positive number a 32-bit signed integer can contain. JGit and older C Git store depth as "int" so both are OK with this number. Dulwich does not support shallow clone.

2012-10-16Documentation/technical: convert plain text files to asciidocThomas Ackermann
These were not originally meant for asciidoc, but they are already so close. Mark them up in asciidoc. Signed-off-by: Thomas Ackermann <th.acker@arcor.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2007-03-20Provide some technical documentation for shallow clonesJohannes Schindelin
There has not been any work on the shallow stuff lately, so it is hard to find out what it does, and how. This document describes the ideas as well as the current problems, and can serve as a starting point for shallow people.
