To help testing little Git-related tool I'm writing, I need a lot of pregenerated SHA1 hashes. Git repo seems to be a perfect source of such. Is there an easy way to extract a list of all (well, most of) SHA1 hashes in the repo? The git rev-list --all gives nice list, but, as I understand, that is only commit objects, and there are much more of SHA1 hidden inside. Thanks in advance, Alexander. ``` ## Peter Harris, 2008-03-23 13:40 Subject: Re: List all SHA1 hashes in repo Message-ID: URL: https://gitlist.dev/e/eaa105840803230640j11ffa096x511a81b1c0b8f40e%40mail.gmail.com In-Reply-To: ``` On Sun, Mar 23, 2008 at 9:17 AM, Alexander Gladysh wrote: > To help testing little Git-related tool I'm writing, I need a lot of > pregenerated SHA1 hashes.

After a "git gc" to roll everything into a single pack, you could do a "git verify-pack -v" to list all the SHA1s in the pack.

Just add --objects.

I thought --all --objects only shows reachable objects? - Pieter (Dscho, sorry for the double post) ``` ## Johannes Schindelin, 2008-03-23 14:33 Subject: Re: List all SHA1 hashes in repo Message-ID: URL: https://gitlist.dev/e/alpine.LSU.1.00.0803231532150.4353%40racer.site In-Reply-To: <540004BB-49C4-456B-ABA3-62659D85C15E@ai.rug.nl> ``` Hi, On Sun, 23 Mar 2008, Pieter de Bie wrote: > On Mar 23, 2008, at 2:59 PM, Johannes Schindelin wrote: > > > The git rev-list --all gives nice list, but, as I understand, that > > > is only commit objects, and there are much more of SHA1 hidden > > > inside. > > > > Just add --objects. > > I thought --all --objects only shows reachable objects? Ah yes. But usually the objects in packs are reachable... So you're right, it does not really show _all_ objects. But it shows many objects, and is pretty easy (which I think was the original poster's real question). Ciao, Dscho P.S.: I got two mails from you, one without the Cc: list, and one with it... Strange. ``` ## Alexander Gladysh, 2008-03-23 15:44 Subject: Re: List all SHA1 hashes in repo Message-ID: URL: https://gitlist.dev/e/c6c947f60803230844s6489422xba49a074d226702a%40mail.gmail.com In-Reply-To: ``` > > > > The git rev-list --all gives nice list, but, as I understand, that > > > > is only commit objects, and there are much more of SHA1 hidden > > > > inside. > > > > > > Just add --objects. > > > I thought --all --objects only shows reachable objects? > > Ah yes.

Sorry for double-posting, Dscho, I forgot Reply to All too. :-) ``` ## Junio C Hamano, 2008-03-23 18:23 Subject: Re: List all SHA1 hashes in repo Message-ID: <7v8x097111.fsf@gitster.siamese.dyndns.org> URL: https://gitlist.dev/e/7v8x097111.fsf%40gitster.siamese.dyndns.org In-Reply-To: ``` Johannes Schindelin writes: > Hi, > > On Sun, 23 Mar 2008, Pieter de Bie wrote: > >> On Mar 23, 2008, at 2:59 PM, Johannes Schindelin wrote: >> > > The git rev-list --all gives nice list, but, as I understand, that >> > > is only commit objects, and there are much more of SHA1 hidden >> > > inside. >> > >> > Just add --objects. >> >> I thought --all --objects only shows reachable objects? > > Ah yes.

"rev-list --objects --all"? ``` ## Johannes Schindelin, 2008-03-23 18:48 Subject: Re: List all SHA1 hashes in repo Message-ID: URL: https://gitlist.dev/e/alpine.LSU.1.00.0803231947530.4353%40racer.site In-Reply-To: <7v8x097111.fsf@gitster.siamese.dyndns.org> ``` Hi, On Sun, 23 Mar 2008, Junio C Hamano wrote: > Johannes Schindelin writes: > > > On Sun, 23 Mar 2008, Pieter de Bie wrote: > > > >> On Mar 23, 2008, at 2:59 PM, Johannes Schindelin wrote: > >> > > The git rev-list --all gives nice list, but, as I understand, > >> > > that is only commit objects, and there are much more of SHA1 > >> > > hidden inside. > >> > > >> > Just add --objects. > >> > >> I thought --all --objects only shows reachable objects? > > > > Ah yes.

I think Pieter's point was that there can be unreachable objects, an this command line does not show them. Ciao, Dscho ```
