I don't know.  I don't remember.  In order to find out, I would either
(1) consult the documentation or (2) try the commands out to see what
happened, or (3) both.  But you can do that as easily as I can.

Re: [fossil-users] Cutting fossil repository

I sent two examples and asked whether they were correct. A simple "yes"
or "no" would be enough...

1) Is the following correct?

fossil purge artifacts 86848307235407

2) can I  delete several commits like this?

fossil purge artifacts 86848307235407 563453457234 56488921223

Thanks.

It's something I've been thinking about [in general] for a while and I
just used this opportunity to inject the idea into the Fossil community.
This seems like the sweet spot with TCL on one side (terrible
documentation/organization) and SQLite on the other (stellar software
engineering).

In this case, the documentation
(https://www.fossil-scm.org/fossil/help?cmd=purge) consists of a
series of examples, each followed by an explanation of what that
example does.

I do not know how to make the documentation any clearer.
Contributions from others who do know how to make better documentation
will be greatly appreciated.

*snide humor alert*

The reluctance of some programmer communities to provide examples has
always surprised me. I think documentation would be much more effective
if there were comprehensive examples throughout. It seems like those
comprehensive examples could be written in a way such that they could be
executed as part of the test suite, mostly as a way to verify that the
documentation is still in sync with the source.

But I come from an electrical engineering education where the goals are
to create clear, concise understandings in the most efficient and
effective way. Open source software communities seem to have different
values/cult'ure.

Re: [fossil-users] Cutting fossil repository

1) But what about the first case? Is the following correct:

fossil purge artifacts 86848307235407

2) can I  delete several commits like this:

fossil purge artifacts 86848307235407 563453457234 56488921223

Thanks.

There is no "shun" command.  Shunning must be done from the web interface.

Re: [fossil-users] Cutting fossil repository

[Zeev Pekar]

Ok, so let me try... Let's say we want to delete a commit 86848307235407

1) using purge it should be:

fossil purge artifacts 86848307235407

2) using shun:

fossil shun 86848307235407 (this is just a guess since this one I
couldn't find in docs)

Am I right?

Thank you.

If you can explain what part of the documentation is unclear, perhaps
we can clarify it for you.

If you need an example in order to pull this off, then it is not
something you should attempt.  The use of purge and shun is for
experts only.  If you do not have a full understanding of what you are
doing, you will likely end up making a mess.

Fossil is designed to never forget things.  You are asking it to
forget, which goes against its very nature.  Some provisions are made
for this, for exceptional circumstances.  But those provisions are
very seldom used, and are not novice-friendly.

Could somebody, please, provide an example of deleting a commit, using
a) purge
b) shun

"shun" rmembers the SHA1 hash and will never again accept that SHA1
hash on a sync.  "fossil purge whatever" simply deletes the artifacts
from the local repo.  They will be restored on a sync from another
repo that holds them.

I think.  Double-check before relying on what I said above.  :-)

Cool.
How does 'fossil purge obliterate' differ from 'fossil shun'?
Is shun obsoleted or superseded by purge now?
Can I achieve the obliteration entirely from the cmd line?

Maybe you could make a copy of the repo then "purge" all those
check-ins and files you don't want from the copy:

Not an easy way, no. Writing a script which pulls one version at a time and
checks them into a new repo would (hypothetically) not be too difficult,
but it would not account for branches/merging without notably more effort.

2) is it possible to delete all the commits (which were made later than

It's hypothetically possible to "pop" versions off the top of a repo, one
version at a time, but it's never been implemented. i looked into it about
3 years ago and found that the it would require a relatively large effort
[for me] to implement, so i abandoned it. :/

[fossil-users] Cutting fossil repository

[Zeev Pekar]

Hello,

if one needs to provide a partial repo (from the beginning till certain
date/commit) to a third party - how should he generate this new partial
repo from the existing full one?

1) is there a way to "cut" a repo till certain date/commit? if yes -
how?

2) is it possible to delete all the commits (which were made later than
the required date) by hand, one by one? if yes - how?

Thank you in advance,
Zeev
