So far I've seen the marks are not the ones provided in the input but some "internal ones" not related with the input. Wouldn't it be much better, for import/export interop, if it kept the original marks? It would be certainly easier to do incremental import/export with external systems not dealing with SHAs... Thanks, pablo ``` ## Shawn Pearce, 2011-03-28 16:25 Subject: Re: git fast-import --export-marks flag Message-ID: URL: https://gitlist.dev/e/AANLkTinpZ%3DPjGpFozCAWscfms6uWBSO2y%2BXqCGGqB2KP%40mail.gmail.com In-Reply-To: <4D90B457.9040607@codicesoftware.com> ``` On Mon, Mar 28, 2011 at 09:16, psantosl@codicesoftware.com wrote: > git fast-import --export-marks is able to export to a file the marks and > its associated commit hashes created during import. > > So far I've seen the marks are not the ones provided in the input but > some "internal ones" not related with the input. > > Wouldn't it be much better, for import/export interop, if it kept the > original marks? > > It would be certainly easier to do incremental import/export with > external systems not dealing with SHAs... I don't know what you are looking at, but fast-import uses the same mark numbers that were supplied in the input stream inside of the exported marks file. Otherwise as you pointed out, the marks are useless. -- Shawn. ``` ## psantosl@codicesoftware.com, 2011-03-28 16:48 Subject: Re: git fast-import --export-marks flag Message-ID: <4D90BBC4.2000908@codicesoftware.com> URL: https://gitlist.dev/e/4D90BBC4.2000908%40codicesoftware.com In-Reply-To: ``` Hi Shawn, > I don't know what you are looking at, but fast-import uses the same > mark numbers that were supplied in the input stream inside of the > exported marks file.

But ok, it seems my marks are "overflowing": >cat fast-export.dat blob mark :1 data 7 bar.c blob mark :2 data 7 foo.c reset refs/heads/master commit refs/heads/master mark :1583217 author unknown 1300813103 +0100 committer unknown 1300813103 +0100 data 8 initial M 100644 :1 src/bar.c M 100644 :2 src/foo.c commit refs/heads/master mark :1583219 author unknown 1300813115 +0100 committer unknown 1300813115 +0100 data 5 move from :1583217 R "src/bar.c" "dst/bar.c" R "src/foo.c" "dst/foo.c" reset refs/heads/master from :1583219 And the generated marks are: :1 d1fe62248992d88f286d03bde972932e0118bf3c :2 146a766f34eb1dfb6c4d7b19a45ddf49ef7e5d5b :1074276465 52f475aba140ca2d6f6eb8f47ef0cdb9d043fab5 :1074276467 caf606bb7cc64bab818acbc52b40d545467ddafc pablo ``` ## psantosl@codicesoftware.com, 2011-03-28 20:47 Subject: Re: git fast-import --export-marks flag Message-ID: <4D90F3F8.1020706@codicesoftware.com> URL: https://gitlist.dev/e/4D90F3F8.1020706%40codicesoftware.com In-Reply-To: <4D90BBC4.2000908@codicesoftware.com> ``` It's working on 1.7, was broken on 1.6 Thanks, pablo On 28/03/2011 18:48, psantosl@codicesoftware.com wrote: > Hi Shawn, > >> I don't know what you are looking at, but fast-import uses the same >> mark numbers that were supplied in the input stream inside of the >> exported marks file.
