            migrate Hg to Git via "fast-export" in Windows
            Asked 2019-Nov-22 at 00:21

            I have a project having mercurial HG code source management,and try to migrate it on a VSTS/Git platform.

            I read that there is a tool for doing that, "fast-export"... So I tried but not did't achieve to do it working in Windows...

            Say I have D:\MyProject containing the .hg directory and the project code files, I

            • downloaded the fast-export files in the "D:\fast-export-master" folder,
            • created a new directory D:\MyProject-git
            • launched in that D:\MyProject-git the git init command (a new .git directory appeared then);
            • now from the same D:\MyProject-git i did
              ..\fast-export-master\ -r "D:\MyProject"

            now strange things starts happening, a command line window appeared and disappeared so quickly I didn't understood what happened, so I relaunched the previous command in a hope to see the message... I should try tens of times until able to capture in the printscreen the command-line message, that says strange things:

            which: no D:\fast-export-master\ in (/c/Users/xxx/bin:mingw64/bin:/user/local/bin:/usr/bin:/bin/mingw64/bin:/usr/bin:/c/Users/xxx/bin:/c/ProgramData/Oracle/Java/javapath:/c/WINDOWS/system32 [...etc...etc...])

            I wonder what is the problem and how to solve it...


            Following the @max630 suggestion bellow, I reinstalled Python and update the PATH, so it's recognized in the command

            There seems to be a bug in the bash bundled with git. It does not initialize "$@" properly if started from directly running .sh file from cmd.

            Switching a Git repository from ISO-8859-1 to UTF-8 encoding for source code files
            Asked 2019-Aug-02 at 14:33

            I'm going to convert a large Mercurial project to Git this weekend using fast-export. I've tested that several times, and the results are good.

            We'd also like to turn our source code encoding (lots of German comments/string literals with Umlauts) from ISO-8859-1 to UTF-8 (all other non-java files in the repo should stay as-is), and the Git migration delivers us a chance to do it now since everybody needs to clone again anyway. However, I don't find a good approach for it.

            1. I've tried the git filter-tree --tree-filter ... approach from this comment on SO. However while this seems ideal, due to the size of the repository (about 200000 commits, 18000 code files) it would take much more time than just the weekend I have. I've tried running it (in a heavily optimized version where the list of files is chunked and the sublists are converted in parallel (using GNU parallel)) straight from a 64GB tmpfs volume on a linux VM with 72 cores, and still it would take several days...
            2. Alternatively, I've tried the simple approach where I perform the conversion simply on any active branch individually and commit the changes. However, the result is not satisfying because then I almost always get conflicts when merging or cherry-picking pre-conversion commits.
            3. Now I'm running approach 1 again but not trying to rewrite the complete history of all branches (--all as ) but just all commits reachable from the current active branches' and not reachable by some past commit which is (hopefully) a predecessor of all current branches (branch-a branch-b branch-c --not old-tag-before-branch-a-b-c-forked-off as ). It's still running but I fear that I can't really trust the results as this seems like a very bad idea.
            4. We could just switch the encoding in the master branch with a normal commit as in approach 2, but again this would make cherry-picking fixes from/to master a disaster. And it would introduce lots of encoding problems because developers would surely forget to change their IDE settings when switching between master and non-converted branches.

            So right now, I somehow feel the best solution could be to just stick to ISO-8859-1.

            Does anyone have an idea? Someone mentioned that maybe reposurgeon can do basically approach 1 using its transcode operation with a performance much better than git filter-tree --tree-filter ... but I have no clue how that works.

            A tree filter in git filter-branch is inherently slow. It works by extracting every commit into a full blown tree in a temporary directory, letting you change every file, and then figuring out what you changed and making the new commit from every file you left behind.

            If you're exporting and importing through fast-export / fast-import, that would be the time to convert the data: you have the expanded data of the file in memory, but not in file-system form, before writing it to the export/import pipeline. Moreover, git fast-import itself is a shell script so it's trivial to insert filtering there, and hg-fast-export is a Python program so it's trivial to insert filtering there as well. The obvious place would be here: just re-encode d.



            Array of objects json stringify and decode - cant access the data
            Asked 2018-Feb-13 at 23:16

            Im building an array of objects which i then stringify and send with ajax, the problem is im not able to loop through the result and get the needed data.

            The whole script doit.php is crashing when i run the foreach loop but if i just echo a random string it will alert and console log that string.




            Answered 2018-Feb-13 at 23:12

            If you only want to access a single column of data and glue the objects/elements together, you don't need to loop and use concatenation.

            I think array_column() and implode() will look cleaner...

            After converting repository from hg to git, how to migrate additional changesets?
            Asked 2017-Jan-06 at 07:44

            After using fast-export to migrate a mercurial repository to git, I've found that open named branches that weren't merged to default weren't converted. Now I want to import the outstanding changesets on these branches to the new git repos.

            I've tried various approaches including hg-git and hg export, but the problem with these approaches is that the changesets or diffs I want to migrate have different changeset ids, and the processes error out since the history cannot be found.

            I'm considering writing a script to automate exporting the changesets from Mercurial, locate the corresponding parent changeset in the new git repo, import to the git stage, and commit, but I'm wondering if a tool for something like this - importing diffs without matching history - already exists. Is there anything out there?



            Answered 2017-Jan-04 at 08:38

            You can convert hg to git by these steps:

            1. In TortoiseHg -> global setting -> Extensions Tab -> select hggit
            2. Create an initial git repo:

            mkdir git cd git git init cd ..

            1. Clone a hg repo and push it to git

            hg clone hg bookmarks hg hg push ../git

            1. In git repo, find the changeset for hg

            cd .. cd git git checkout hg git log

            Then you will find the log histories.


            If you still want to use faste-export to migrate. You can try below steps:

            Inspired by migrate from mercurial to git, we can also create a changeset mapping file by hg log | grep changeset: | sort | uniq | sed 's/changeset: *//' > ../changeset.

            When migrate hg to git just try /path/for/fast-export/ -r /path/for/hg-repo -A /path/for/changeset instead (beacause windows OS seems has trouble to, so sorry for that I can’t try it before update the answer).
