 Repeated exports are done efficiently, by diffing the old and new tree,

+If a directory special remote, which is configured with exporttree=yes
+but without importtree=yes, has a file written to it not by git-annex,
+a later git-annex export of a file with the same name but a different
+content fails to overwrite it, but the output of the command indicates
+the export succeeded.
+
+Of course, it's fine for the file to be overwritten. The user is not 
+supposed to be writing files to such a location themselves; if they
+want such files preserved they need to use importtree=yes. 
+It would also be fine for the command to error out.
+But it's surprising for it to silently fail to write to it.
+
+This is not limited to the directory special remote. It happens because
+`checkPresentExport` is used to check if there is a file in the export
+location and it's skipped being written if so, under the assumption
+that the export already was done in another clone of the repository.
+See [[!commit c3fa1f2b0869a87a9788ebbf881993c8093f3196]].
+
+Would it be possible to deal with that better? The export log should
+indicate if the file is known to have been exported to the special remote,
+and so it should be able to skip trying to re-export it in that case,
+without needing the `checkPresentExport`.

+If the web special remote supports it, does it also make sense for any
+other special remotes to support it? Not *all* of them, since that is
+impractical.
+
+Since implementing this is as easy as swapping `withUrlOptions` to
+`withUrlOptionsPromptingCreds`, I grepped for that. The special remotes
+it may make sense for are bittorrent, httpalso, and external.
+
+bittorrent I think might as well, it's very much like the web special
+remote.
+
+httpalso seems like a reasonable use case too
+
+external could for `DOWNLOAD-URL` -- which is already documented to
+support git-credential but did not. Oops. Also `TRANSFER-RETRIEVE-URL`,
+`CHECKPRESENT-URL`, and `RETRIEVEIMPORT_URL`, which I think should support it.
+
+But external special remotes with `remote.name.annex-externaltype=readonly`
+should not; that is documented to be for cases where no authentication is needed
+to download.
+
+One remote where it would not make sense is S3, which uses withUrlOptions
+in only when "publicurl=" is configured. Which is not supposed to involve
+password prompting, and if it did support git-credential, would be very
+confusing since that is different from the usual S3 authentication.
+
+Also, `git-annex addurl` and `git-annex importfeed` could support

+I started writing docs for `remote.web.annex-gitcredentials`,
+and quickly realized that it's confusing that, for a git remote,
+`remote.<name>.annex-gitcredentials` is not needed in order for git-credential
+to be used, while for a web special remote, it is needed.
+
+That makes me wonder if the config is needed at all, or if it should
+default to true. Either choice would mean that the security considerations
+need to be considered again.
+
+But: A git remote can also be set up to be autoenabled, with an attacker
+controlled url. In that case, git-annex will already use the git credential
+config when accessing files in that git remote, and so will git when
+pulling from that remote.
+
+So, there does not seem to be any additional security exposure in making the
+web special remote use git-credential by default.

+I think if there is a config that is only used by the web special remote,
+it needs to mention the web special remote in its name (or value) somehow.
+
+So rather than `credential.<url>.annex-ignore = false`, something like
+`credential.<url>.annex-web-special-remote = true`. But that is a mouthful.
+
+Or `remote.web.annex-gitcredentials = true`. Which avoids git-annex needing
+to handle `credential.` config matching at all, git-credential would use
+whatever configs are set.
+
+That would make the web special remote use git credential for any urls that
+need auth. Which may be too broad for some use case I suppose, but if the
+user wants it to only be used for some specific urls, they can make a
+separate web special remote with `urlinclude=` and set the git config for
+that remote.

-Hello everyone.
-
-Be aware that your distribution's package may be very old.
-For example, at the time I write this, latest Debian stable is Debian 7.5 which is 2 months old.
-But git-annex package there is two *years* old (tomorrow, it will be exactly two yezrs old).
-
-So, beware.  If following [online walkthrough](https://git-annex.branchable.com/walkthrough/), either install a more recent git-annex (e.g. from [Debain backports](http://backports.debian.org/Instructions/)) or follow instructions from your local `/usr/share/doc/git-annex/html/walkthrough.html` instead.

 ## Installation (Termux)
 
-First, install [Termux](https://termux.com/). This is an Android app that can
-run some Linux software in a terminal, including git-annex.
-
-git-annex is not currently part of the Termux distribution, but it's easy
-to install it. Paste these commands into Termux:
-
-	pkg install wget
-	wget https://git-annex.branchable.com/install/Android/git-annex-install
-	source git-annex-install
+See [[/install/termux]]
 
 ## Installation (Nix-On-Droid)
 
-Installing git-annex using
-[Nix-On-Droid](https://github.com/t184256/nix-on-droid) is recommended
-for more advanced users who want to use git-annex at the command line.
-The git-annex webapp does not currently work in Nix-On-Droid (as a workaround, run `git annex webapp --listen 127.0.0.1` and copy-paste the URL in a browser).
-
-To enter a shell with git-annex available to use,
-run inside Nix-On-Droid: `nix-shell -p git git-annex`
-
-To avoid needing to do that every time you start Nix-On-Droid,
-you can add git and git-annex to your `environment.packages` in 
-`~/.config/nixpkgs/nix-on-droid.nix` and then run 
-`nix-on-droid switch`
-
-## Starting git-annex assistant
-
-Just run "git-annex webapp" inside Termux.
-A browser window will open with the git-annex interface.
-
-[[!img webapp.png alt="git-annex webapp"]]
-
-## Closing and reopening the webapp
-
-The webapp does not need to be left open after you've set up your
-repository. As long as Termux (or Nix-On-Droid) is left open, git-annex 
-will remain running and sync your files.
-
-## Starting at power on
-
-If you install the [Termux:Boot app](https://wiki.termux.com/wiki/Termux:Boot),
-git-annex will be automatically started when your Android device
-powers on. It will run in the background in whatever repositories you have
-set up in the webapp.  
-
-## Using the command line
-
-If you prefer to use `git-annex` at the command line, you can do so inside
-Termux or Nix-On-Droid. Here we'll make a repository for photos:
-
-        cd ~/storage/dcim
-        git init
-        git-annex init
-
-You can go on to set up a ssh remote pointing to a server, and sync
-your files to and from it.
-
-And so on. Most ways you would use git-annex on a Linux system work fairly
-well in the Termux environment.
-
-## Upgrading (Termux)
-
-To upgrade to a new git-annex release, just run `git-annex-install` again.

+Hmm, this behavior is not limited to balanced lackingcopies. 
+Eg "balanced=pool:2" will keep 3 copies if there are already 3, until
+--rebalance is used.
+
+But in that case, the only way there can be 3 copies is if one is manually
+made. And one reason to manually make an extra copy might be when moving a file
+between two nodes of the pool, where it's copied to the new node first,
+and then dropped from the second. It seems that the user would not want
+a `git-annex sync` run in the middle of that process to undo their copy.
+
+And the documentation does mention that:
+
+	Some of the ways that it can get out of balance include [...]
+	a file getting copied into more repositories in the
+	group than the specified number
+
+In the case of eg, "balanced=pool:lackingcopies=backup", a new backup
+repository could be set up, and get a copy of a file (backup repositories
+want all files). Then the file would have more copies in the pool than the
+expression wants it to have.
+
+Is that different enough to justify a different behavior of dropping a copy
+from the pool? At this point, before balanced lackingcopies is in a release,
+it can be done without being  a behavior change still. It would be harder
+to justify it as a later behavior change.
+
+What about the similar situation with a manual move between nodes
+with balanced lackingcopies? It seems the same reasoning applies to that as
+to balanced copies.
+
+But then, how to make it want to drop in the one case, and not in the other case?
+
+Maybe better to leave this up to the user. They could use eg 
+"balanced=pool:lackingcopies=backup and not excesscopies=pool+backup=1"

+### Please describe the problem.
+`git annex export` to a directory special remote can delete pre-existing files
+that it never wrote.
+When export encounters a path that already exists on the export remote, it does
+not overwrite it — the existing file's contents are left untouched. But it still
+prints `export <remote> <file> ok` and records the file as exported. That record
+later authorises a deletion: once the exported tree stops listing that path,
+export prints `unexport <remote> <file> ok` and removes the pre-existing file.
+So the behaviour is asymmetric in an unfortunate direction: too conservative to
+overwrite a file it does not own, but willing to delete that same file later.
+### What steps will reproduce the problem?
+Set up a directory holding data that git-annex did not put there:
+	mkdir -p /tmp/target
+	echo "PRECIOUS-PREEXISTING-DATA" > /tmp/target/a.txt
+	echo "ALSO-PRECIOUS"             > /tmp/target/keep.txt
+Make an annex whose tree happens to contain a file of the same name, plus one
+new file:
+	mkdir /tmp/work && cd /tmp/work
+	git init -q .
+	git annex init -q work
+	echo "DIFFERENT-CONTENT-FROM-TREE" > a.txt
+	echo "new"                         > b.txt
+	git annex add a.txt b.txt
+	git commit -qm tree
+	git annex initremote t type=directory encryption=none \
+	    directory=/tmp/target exporttree=yes
+Export:
+	$ git annex export main --to t
+	export t a.txt ok
+	export t b.txt ok
+	$ cat /tmp/target/a.txt
+	PRECIOUS-PREEXISTING-DATA
+Note `a.txt` was reported as exported, but its contents were (correctly) not
+overwritten.
+Now export a tree that no longer contains those files. The empty tree is used
+here for brevity; in practice this is just an ordinary change that drops a path.
+	$ git annex export $(git hash-object -t tree /dev/null) --to t
+	unexport t b.txt ok
+	unexport t a.txt ok
+	$ cat /tmp/target/a.txt
+	cat: /tmp/target/a.txt: No such file or directory
+	$ cat /tmp/target/keep.txt
+	ALSO-PRECIOUS
+`a.txt` is gone. Its contents were never exported by git-annex, and never
+existed anywhere in the annex — they are simply lost.
+`keep.txt` survives, which isolates the cause: it was never named in an exported
+tree, so no export record was created for it. Deletion follows the export
+record, and the export record was created for a file that was never written.
+### What version of git-annex are you using? On what operating system?
+10.20251215 on Linux (Manjaro, x86_64). Also reproduced with a build of
+10.20260718 from git.
+### Please provide any additional information below.
+The impact depends on what else lives in the export remote's directory. If it
+holds a checked-out git repository, the deletion can remove that repository's
+`.git/config`, `HEAD`, `refs/*`, `logs/*` and hooks in one pass — every one of
+which export had previously declined to overwrite. In a test here that took a
+working repository from 31 files to 4, after which `git log` in it reported
+`fatal: not a git repository`.
+A couple of related observations from the same testing, in case they are useful:
+* Exporting to an *empty* directory writes every file in the tree as expected,
+  so the non-overwriting behaviour above is specific to paths that already
+  exist.
+* Once export has written a file, later modifying that file on the remote and
+  re-running export does not restore it, with or without `--force`.
+I have deliberately not proposed a fix, since the right behaviour is a design
+question — whether export should refuse such a path, warn, overwrite it, or
+simply not record a file it did not write, all have different consequences for
+existing users.

+### Please describe the problem.
+
+There appears to be an issue with the mask remote with encryption: annex-copying several files stalls after first file.
+
+I first noticed this issue with forgejo-aneksajo and reported as <https://codeberg.org/forgejo-aneksajo/forgejo-aneksajo/issues/125> - only then did I realize that this also affects bare repositories. I added a comment to the forgejo-aneksajo issue and will amend it further, linking to this issue here.
+
+### What steps will reproduce the problem?
+
+This would create a repo with four small files and try to push it to an encrypted mask remote:
+
+```
+git init /tmp/foo
+git init --bare /tmp/local-bare-repo
+cd /tmp/foo
+for n in {1..4}; do head -c 1M < /dev/urandom > f$n.dat; done
+git annex init
+git annex add *dat
+git commit -m "Add 4x1M"
+git remote add local /tmp/local-bare-repo
+git annex sync --no-content local
+git annex sync --no-content local
+git annex info local | grep uuid
+git annex initremote local-mask type=mask remote=local encryption=hybrid keyid=<GPG KEY ID HERE>
+git annex copy --to local-mask
+```
+
+This stalls for me after the first file (ie. after printing copy f2.dat) and I interrupt with Ctrl+c.
+
+On one attempt I got "gpg: signal Interrupt caught ... exiting" after Ctrl+c but usually I got nothing.
+
+### What version of git-annex are you using? On what operating system?
+
+I tried this on two systems:
+
+- git-annex 10.20260717 (from PyPI), git 2.47.3, gpg (GnuPG) 2.4.7 on Debian GNU/Linux 13 (trixie)
+- git-annex 10.20250416, git 2.39.5, gpg (GnuPG) 2.2.40 on Debian GNU/Linux 12 (bookworm)
+
+
+### Please provide any additional information below.
+
+This seems to be specific for copying multiple files, because copying the files one-by-one works fine:
+
+```
+git annex copy f1.dat --to local-mask
+git annex copy f2.dat --to local-mask
+git annex copy f3.dat --to local-mask
+git annex copy f4.dat --to local-mask
+```
+
+This seems to be specific to the mask special remote (and not just a problem with gpg), because e.g. copy to directory remote works:
+
+```
+mkdir /tmp/safe
+git annex initremote safe type=directory directory=/tmp/safe encryption=hybrid keyid=<GPG KEY ID HERE>
+git annex copy --to safe
+```
+
+And it does not seem to be specific to copy, since (after pushing files one by one) fsck shows similar behavior (all at once stalls, one-by-one works).
+
+```
+❱ git annex fsck --fast --from local-mask
+fsck f1.dat ok
+fsck f2.dat ok
+fsck f3.dat    # stalls here
+```
+
+### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
+
+Plenty - and I think I must have used mask special remote with more than one file before.

+> @yoh what do you think about that idea?
+
+I might be missing the point for extra parameter (`urlinclude`) for web remote itself as it might complicate handling multiple `<url>` settings, and overall feels more of a user/system wide configuration and not remote.
+
+As for the need of support by all special remotes -- now that there is a [`DELEGATE`](https://git-annex.branchable.com/design/external_special_remote_protocol/delegate_appendix/) functionality for special remotes, I think special remotes should generally be advised to just delegate HTTP downloads to git-annex for robust/centralized operation overall where feasible.  Then it would fall under centralized `credential.<url>.` handling by git-annex. 
+
+Related: just an idea, what about adding `credential.<url>.annex-ignore` defaulting to `True`, just to let folks where needed explicitly set to `False` so to tell credential provider to be used for that `<url>`?  Since manual configuration of a `credential.` is anyways required, IMHO it is ok to request explicitly specify if it should apply to git-annex or not, with default being \"not\".

+There are some fairly related todos that I have been thinking about
+recently.
+
+* [[todo/extraheader_config]] wants `http.<url>.extraheader` to be
+  supported at least for P2P over HTTP urls 
+* [[todo/Support_per_SITE_http.SITE.sslCAInfo_etc]] 
+  for `http.<url>.sslCAInfo` and `http.<url>.sslCAPath`.
+
+Each of those has their own considerations around things like security
+and what is able to be implemented sanely.
+
+Those are about `http.<url>.*`, while this is about
+`credential.<url>.*`. git has different matching rules for those.
+For `http.<url>.*` git's documentation explicitly limits it to
+
+	The URLs that are matched against are those given directly to Git com‐
+	mands. This means any URLs visited as a result of a redirection do not
+	participate in matching.
+
+For `credential.<url>.*` git's documentation is less explicit about
+exactly which urls it applies to.
+(I also noticed that at least the design document `technical/bundle-uri.adoc`
+talks about using git credential for accessing bundle urls that are 
+provided by the git server. I don't know if that is implemented in git though.)
+
+I think it's important that whatever git-annex does about these per-url
+configs, it does it consistently. A small divergence from git's documented
+behavior would be ok as long as it's documented and doesn't open security cans
+of worms.

+However, that could lead to a security hole...
+
+For example, suppose a user has read the git documentation
+above, and knows that `http.<url>.extraheader` will only be used for urls

+they'll be using under `sharedhosting.com` are under foo.sharedhosting.com

+As a workaround ATM we use [datalad special remote](https://docs.datalad.org/en/stable/credentials.html#let-datalad-query-git) which then queries the git credential.  But I feel that it would be smoother and warranted for git-annex to perform such authentications in case of git credentials being configured.

+I ran into this error during the `export` of a view to FAT32.  At least some of the problems were caused by how git-annex constructed the view's filenames (or temporary transfer filenames), I believe.  The filenames are constructed from path elements, which may get truncated, and so the final filenames could end up with trailing spaces.  Upgrading to the current version has fixed almost all of those errors.
+
+What appears to continue to be a problem are filenames with percentage signs in them, e.g., `foobar 100%.bin`.  As far as the filesystem is concerned, `%` characters themselves are obviously fine, because git-annex uses them for all view branch filenames, and the export generally works for them.  (For now, I've renamed files to, e.g., `foo 100 percent.bin`, and it works 100% now. :) )

+Okay good news! I was able to do some digging and realized that the marking a remote as dead and removing it wasn't removing it fully. When you examine `git config --list` it shows there is some information regarding that remote (remote.b2.annex-s3=true, remote.b2.annex-uuid=f7132f57-5ab6-4fe5-b7ce-d9ea5b24e2e0, remote.b2.skipfetchall=true
+ and remote.b2.annex-cost=1000), but running `git config -e` and deleting everything in the b2 field grouping allows `git annex info` to work as expected.

+Hi,
+
+I'm having an issue and have exhausted my troubleshooting steps. First of all, no LLM was used in debugging, troubleshooting or similar. All mistakes made and all steps, were done by a human who spent many hours pouring over Branchable and seeing if I could find a similar issue.
+
+The TDLR is 
+
+When I run `git annex info` :
+
+It returns the following error : 
+
+```git-annex: Uncaught exception ghc-internal:GHC.Internal.Exception.ErrorCall:
+
+S3 bucket not configured
+
+While handling S3 bucket not configured
+```
+
+I expect it to return something like this (which it did in the past before I marked dead and dropped the remote):

+I created an S3 compatible special remote using the following command.
+
+`git annex initremote b2 type=S3 host=s3.ca-east-006.backblazeb2.com embedcreds=yes encryption=hybrid keyid=B166A700 bucket=ed85a29bf12dc1fe9ff60310 protocol=https signature=v4`
+
+I was able to successfully upload multiple files to the remote, and verified their existence from the remote's console. 
+
+## Steps leading to this mistake
+
+1) Created a special S3 remote `git annex initremote b2 type=S3 host=s3.ca-east-006.backblazeb2.com embedcreds=yes encryption=hybrid keyid=B166A700 bucket=ed85a29bf12dc1fe9ff60310 protocol=https signature=v4`
+
+2) Marking the remote as dead using `git annex dead b2`
+
+3) Dropping dead remote using `git annex forget --drop-dead --force`
+
+### Possible asides or useful information
+
+1) I'm unable to recreate the remote as it says it already exists
+
+2) When I run `git annex info --debug` it shows the following information (redacked email and name) rest remain unchanged

+Currently, preferred content "balanced=groupname:lackingcopies"

+Internally, the reason this behavior happens is that

+I got as far as implementing a git compatible config matcher,
+in [[!commit 6f43e386788eb01e944f98df0d6ed6eb79b84e76]].
+
+But, it's difficult to see a way to implementing this for
+http.sslCAInfo and http.sslCAPath. It needs to somehow be fed into
+http-client's Manager. But a Manager is set up outside any code path
+that knows what url is being downloaded. And nothing in the Manager
+API lets it override its ConnectionContext based on the url being requested.
+
+I think that UrlOptions would need to change httpMananger to an IO action
+that takes the url. And then to be performant, there would need to be
+caching of Managers, so that once a manager is created using a given
+http.sslCAInfo or http.sslCAPath, that same Manager keeps being used
+for other urls that use the same config values.
+
+But the fun doesn't stop there, because Manager is a core data type
+used by other haskell libraries. Eg, in Remote.S3, git-annex passes
+a Manager into `aws`, and so has no visibility about what urls
+that Manager will be used for.
+
+And that shades into another problem --
+"http.<url>.*" documentation includes this:
+
+	The URLs that are matched against are those given directly to Git com‐
+	mands. This means any URLs visited as a result of a redirection do not
+	participate in matching.
+
+If git-annex follows that, it would need to distinguish when an url is
+user-provided enough to use that config and not.
+
+When using Remote.GitLfs to download an object, there is essentially a
+redirect via the git-lfs protocol. Should that url be matched against
+the git config? Seemingly not. But in the aws case, the S3 publicurl= 
+value was provided as an input to git-annex annex command.
+So it seems that it should.
+
+What does it mean for the url to be given directly to a git(-annex)
+command? The `git clone` url certianly was. The S3 publicurl= value was
+provided by *someone* but it may not be the user using the remote now. And
+similarly a `git-annex get --from web` may be run by someone other than the
+person who ran `addurl`. 
+
+And `git-annex importfeed` discovers other urls, but is otherwise
+equivilant to the user running `git-annex addurl` themselves on those urls.
+In one case the user gave the url to a git-annex command, and in the ther
+case they did not. It does not really make sense for git-annex to
+distinguish those two cases, but either thing it picks will violate the git
+documentation.
+
+Now, git-annex could choose to diverge from git and always use the config.
+But bear in mind that [[todo/extraheader_config]] is asking some very similar
+questions about another `http.` config. Which could be a security hole if it
+exposes the config to the wrong urls.
+
+What might make sense would be for git-annex to support 
+`http.<url>.sslCAInfo` and `http.<url>.sslCAPath` only where git
+does. So for a git remote url, and not for anything else.
+I think that would also make sense for the [[todo/extraheader_config]].

+`git-annex drop --auto --from` a remote when the remote's preferred content
+expression is "present" and when the key is not present will do
+work to drop the key, unless --fast is used.
+
+In the vast majority of cases, that is unncessary work. Only if the
+location tracking is out of date and the remote actually has the content
+does the content get dropped. 
+
+(As well as being unncessary work, it looks pretty weird. I thought
+for a while that my preferred content expression was broken or that
+git-annex was dropping things it shouldn't.)
+
+Generally drop does not default to --fast because the goal is that
+dropping a specific file from a remote really guarantees that the remote 
+does not contain the file. Even if the local repository is not in sync.
+
+In this case though, the drop is not dropping a specific file, it's
+working to satisfy the preferred content. If the local repository is out
+of sync there are surely other ways that a preferred content expression
+won't be fully satisfied. For example, if a repository only wants content
+when no other repository in its group contains it, the local repository
+being out of sync can make a drop not happen when it "should" 
+(or happen when it "shouldn't").
+
+It might be that the solution to this is to make `drop --auto` default
+to `--fast`. Or a more targeted solution that checks if the preferred
+content depends on location tracking might be better. Unsure. I'd lean
+toward the simpler one.
+
+Note that `git-annex sync` only drops from remotes that location
+tracking thinks contain the content. So this would bring `git-annex drop
+--auto` into alignment with it.
