Unable to get Unison to sync current folder onto remote folder - macos

I am trying to automate backup of my project folders through a script. I found Unison, which seemed to match my needs, and have writtenm a script that can reliably mount and unmount a samba folder (Mac backing up to a Windows box). The only problem I am having is getting my unison command to reliably backup my (currently test) directory. It says:
Looking for changes
Reconciling changes
Nothing to do: replicas have not changed since last sync.
Which doesn't make sense to me.
Here is my command:
unison ~/Documents/test ~/hm_mnt/test/ -fat -auto -force ~/Documents/test -noupdate ~/Documents/test -nodeletion ~/Documents/test
I want to simply maintain a copy of the current state of my test folder in this case. this worked once and has not duplicated since.
My initial run (with slightly different command run fine) and I have been refining it to the above state since trying to get manual updates to a test file to move over. These have not propagated, and even when I cleaned out the remote folder to make sure there was no differences detected.
Thanks

Is there any way to inspect the contents of the RocksDB instance used by NEAR Protocol?

Disclosure: I work with NEAR and am currently on-boarding.
When I start up a local node on a clean machine I see that a .near folder is created in my home directory with a few configuration files (exact files seem to depend on which start_ script I run). Another folder appears inside of the .near folder called data.
Running strings ~/.near/data/*.sst in the folder spits out a few lines starting with the string "rocksdb" which led me to this reference to RocksDB
Is there any way to inspect the contents of a node's RocksDB instance?
I found Keylord but it crashes when I try to configure a new connection to the database (by pointing the connection to ~/.near/data). I didn't pursue that thread.
PSA1: sometimes it's useful to backup the ~/.near folder between node restarts if you want to reset the environment or avoid reusing old data while troubleshooting
mv ~/.near ~/.near_`date +%Y-%m-%d.%s`
PSA2: on MacOS you can watch what happens to the contents of the ~/.near folder while the node boots up and runs. (brew install watch).
watch -d -c -n 0.5 find ~/.near
The content of RocksDB is serialized using our own binary serialization format (http://borsh.io/), so you won't be able to examine the content with general-purpose third-party tools

Illegal Byte sequence in a file name while checking out git branch

I am using git in cli to change the current branch:
git checkout dev
and it produces:
fatal: cannot create directory at 'app/src/androidTest/java?com': Illegal byte sequence
As answered in this question and this one, I tried:
LC_ALL=C git checkout dev
or
LC_CTYPE=C git checkout dev
but I am getting the same error as shown above.
Running:
git status
shows that some of the files were changed by the checkout, but I am still on the master branch.
How can I remove the file causing the problems or how can I checkout the branch without getting this error?
The locale only affects how things are displayed. If the file name contains a character which isn't allowed by the file system, no amount of locale tweaking can fix that.
I can't think of a way to force a file system to let you create a file which then cannot be used, or a good reason to want to be able to do that.
Probably as a workaround, create a virtualized host with a bare-bones Linux system formatted to permit old-style 8-bit file names (Latin-1 or CP1252 if you can live with the unsavory Windows flavor of that), check out the file there, rename and commit the rename back to git. You still won't be able to check out versions of the source tree from before the rename.
I have found a few files in various github projects that are not compatible with one or another operating system. Files with a ".nul" or ".con" extension are a real pain on windows, for example. It isn't a problem exclusive to git. For example Subversion will abort nastily if it can't restore a file for local naming reasons.
In some cases the file may have been uploaded in error. If that is the case for your own projects it should be possible to use the git tools to list the archive and perform a delete of the file from the archive without actually instancing the file locally.
In other cases perhaps that particular file is not significant, and perhaps can be ignored. Perhaps a test will fail if it is missing?
One trick I have used is to stop the whole folder containing that file from being synced by manually creating the directory path, but for the last element, create an empty file instead of a folder. Of course, now the whole test suite will fail.
When the version control tries to do the checkout, it will simply fail to restore the folder, rather than giving a fatal error.
Of course, that only works if the folder is non-critical, e.g. some test files.
The alternative is to piecemeal check-out all but the problem file, but that can be a tedious sequence of checkouts. But you can use this attack to restore the rest of the folder that you omitted using the above technique. Alternatively, locally drag the files from the zip download if they are non-critical.

Unable to find TeamCity 9.1.x data directory

This is really weird.
I am trying a clean Teamcity 9.1.1 install but the Data Directory is nowhere to be found.
if I access the Global Settings tab under Administration, it lists "C:\Windows\System32\config\systemprofile.BuildServer" - a folder that doesn't exist.
if I try to browse to that folder, it shows me a range of files; uploading a specific file there instead uploads it to C:\Windows\SysWOW64\config\systemprofile.BuildServer.
there is no teamcity-startup.properties file anywhere - I am unable to customize the location of the data directory.
when I restore a backup, the backup files are instead restored to C:\Users\[user name]\.BuildServer rather than in the correct data directory.
Does anyone has any suggestions on how to regain control of the situation? How can I tell TeamCity which data folder to use?
I resolved the situation by:
stopping TC services;
creating a teamcity-startup.properties in [install folder]\conf with the following content:
teamcity.data.path=D:\\[install folder]\\config
restarting TC services;
restoring my backup.
This restored the 9.1.1 install as well as stabilizing the location of the data directory. After this was done, the subsequent installation of 9.1.7 prompted me to uninstall 9.1.1 first (which it hadn’t done the first time around) and the upgrade succeeded.
I believe the system was already compromised at the beginning, unknown to me, due to the data folder being all over the place. Once that was resolved, everything else fell into place.

backup collabnet subversion edge to another hard disk

I've installed Collabnet Subversion Edge, and would like to make sure I have it backed up properly. I would like NOT to use the CloudBackup service offered.
I've went to the administration interface for collabnet (localhost:3343) and went to Repositories > Backup Schedule. There, one can choose between 3 different 'Type of Job':
Cloud Services Backup
Full Dump Backup
Hotcopy Backup
Neither lets you choose where to copy the backup. I've tried looking up how this works, but documentation seems to be lacking a lot.
What is the best way to backup such a repository? Shall I just keep a copy of the entire collabnet folder (c:\csvn)?
The Subversion Edge admin UI lets you specify the folder for backups. It defaults to a folder inside the normal data folder, but you can specify a different value. So, for example, if you have a D:\ drive that you want the backups to go on you can just specify that folder in the settings and the backups will go to that folder.
It does need to be a physically accessible hard drive though.
See the Backup Directory configuration item in this screenshot:
https://ctf.open.collab.net/sf/projects/svnedge/screenshots/screens/config/config.png
You can use Windows Server Backup to backup Subversion repositories. It allows you to shedule backups
to a network share, dedicated backup volume, writeable media. For example, wbadmin command-line tool allows you to safely backup your repositories. This simple command performs one-time copy backup of C:\foo\bar to X:\ volume:
wbadmin start backup –backupTarget:x: -include:c\foo\bar -vsscopy
(To install Windows Server Backup, run ocsetup WindowsServerBackup in elevated command-prompt).
You can setup backup in different ways:
wbadmin command-line tool,
PowerShell cmdlets, good for automation and customization of backup actions,
Windows Server Backup wizard (control panel, actually) MMC snap-in.
It's not required to stop server's service when you run the backup because FSFS repository backend is always in consistent state.
Here are general tips about recovering Subversion repository from a backup:
Recover repository backup to an empty directory to make sure that restored repository files won't mix with files of the broken one. After repository if recovered, you can delete broken repository and then replace it with the recovered one.
Stop-start cycle your Subversion server after recovering repository from a backup.
If your clients get errors after repository recover, run svnadmin recover against it. The command finishes instantly and makes repository accessible again.
If you have access to the repository directories then you should be able to use hotcopy directly and specify where the backups go.
It's enough to take a periodical backup of just csvn/data directory where all your repositories and configuration files are stored.

Manual Upgrade/Reinstallation Steps
Subversion Edge includes an integrated mechanism for installing updates. This is the preferred way to do an upgrade as it handles whatever steps are needed to perform the upgrade and can be done remotely from your web browser. However, there are scenarios where you might want or need to do an upgrade manually, for example your Subversion Edge server might not be able to access the Internet to pull down the updates or maybe one or more critical installation files have become corrupted and you need to reinstall using the same version. Here are the steps for performing a manual upgrade or reinstallation:
Windows
If your existing Subversion Edge installation was installed using the installer from Subversion Edge 2.0.0 or later, then all you need to do to upgrade is download the latest installer and run it. This will uninstall the current version and install the new version (which is how the Windows Installer (.msi) process works for upgrades).
If you are not sure what version you installed with, you can always safely use this approach:
Stop the existing services and uninstall the current version from the
Windows Control Panel. This will leave behind your C:\csvn folder and
any files in it that have been modified since the original install.
Delete everything in the C:\csvn folder EXCEPT the data folder. So
you should be left with just the C:\csvn\data folder.
Install the new version. The installer will pick up the existing data folder and when the services start it will basically just be an upgrade to the new
version.
WARNING: Take note of this reported bug and backup the svn_access_file first:
artf7081 - Using Windows installer for updates can overwrite the svn_access_file
Linux/Solaris
To upgrade a Linux/Solaris installation, this is the safest way to do it:
Stop the servers $ bin/csvn stop $ bin/csvn-httpd stop
Rename the csvn folder $ mv csvn csvn-old
Untar the new release as a non-root user
Move the data folder back into the new release
$ mv csvn-old/data csvn
Important! Copy "dist" configuration files to data folder
$ cp -f csvn/dist/*.dist csvn/data/conf
Start the servers
$ bin/csvn start
$ bin/csvn-httpd start

Subversion control No Such file or directory. Can't open file

Error message :
"svn: Can't open file '/Users/username/Projects/myproject/trunk/project/.svn/text-base/filetoupdate.h.svn-base': No such file or directory"
Question:
I have an issue I've replaced a file in a project (in Xcode) with a new file (For reference and if this makes a difference, the new file has the same name as the one I deleted previously).
Now when I try to commit my changes in Xcode I get the error message detailed above and am unable to commit the changes (i.e. adding the new file).
In the file system view (in Xcode on the left hand side of the screen) the file has an R next to it (indicating Replaced in the repository).
Does anyone know how to fix it so I can commit the files?
Thanks
There is a bug or limitation in Subversion when using case-insensitive filesystems:
https://superuser.com/questions/303348/cant-checkout-in-subversion
This bug normally shows up when checking out a repository that contains two files whose names differ only in case. Of course, these cannot exist at the same time in the same directory on a case-insensitive filesystem. SVN could give a much more helpful error message, but it can't really solve the problem.
Your issue is a bit different because I assume the file filetoupdate.h (with the old case) no longer exists in your filesystem. So it's not a case conflict in the working directory. But I guess that SVN is trying to create the file in .svn/text-base with the new case, while the old one still exists, and that is failing (for the same reason).
You could try deleting the file from Subversion first, keeping the local copy (untested). The new copy must be removed from SVN control for the commit to succeed:
svn rm --keep-local --force FileToUpdate.h
And the old copy must be removed as well, to allow us to add the new copy later:
svn rm --keep-local filetoupdate.h
Commit this change:
svn commit
Now hopefully you can add the new file to version control:
svn add FileToUpdate.h
If that doesn't work, you might need to blow away the whole checkout and start again with a fresh one.
Are you on a Mac or Windows? Those have case-insensitive filesystems which causes the above problem when
a file currently exists with the same name but with different cases.
To fix , checkout out the tree on a Linux machine, then "svn rm" one of the files.
Maybe your local version has permission issues. Check if your user have the permissions to write for the .svn directories.
good luck
It looks like something got confused somewhere. To fix, I simply copied the offending files, saved them under a new name. Removed the originals from the project and the added the copied (renamed) version of the file to the project.
It seems to be that SVN doesn't like it if you add and remove a file with the same name. I tried cleaning the SVN through terminal, but it had no affect on this issue. But changing the name did work for me.
