+The botan flag allows avoiding the dependency on crypton, instead depending on botan which is free from LLM generated code and better supported. More info in the blog entry [no llm code](https://git-annex.branchable.com/no_llm_code/#index7h3).

+### Please describe the problem in your own words.
+
+crypton 1.1.0 switched from memory to ram, the latter providing the same interface with its own definitions. Thus, using memory is incompatible with crypton 1.1.0.
+
+### What steps will reproduce the problem?
+
+Build the latest release 10.20260901 against crypton 1.1.0.
+The build fails with an error message regarding mismatching types.
+
+### What version of git-annex are you using? On what operating system?
+
+* OS: Arch Linux
+* Kernel: Linux 7.2.6-arch2-1
+* GHC: 9.6.6
+* git-annex: 10.20260901
+* crypton: 1.1.0
+* memory: 0.18.0
+
+ram: 0.22.1
+
+### Please provide any additional information below.
+
+The relevant imports explicitly mention the memory module: `import "memory" ...` and `import qualified "memory" ...`. Without the explicit module mention, it would work as-is, as ram provides the same interface.

+Use case is wanting to set up a server with a git-annex repository which is
+a mirror of an original repository.
+All git refs are mirrored, using eg `git push --mirror`.
+
+So, the git-annex branch cannot diverge. Or if it does, any divergence will get
+overwritten the next time the refs mirror is updated.
+
+The mirror can contain some, but not necessarily all annex objects as the
+original repository. If a client requents an annex object that is not
+present in the mirror, it transparently proxies the request to the original
+repository. It may also, optionally, cache the object in the mirror (if 
+the mirror's preferred content configuration wants it).
+
+A client dropping an object from the mirror would have it proxy the drop to
+the original repository, and only delete its cache if that drop succeeded.
+
+It seems at first that the mirror repository would need to have
+the same uuid as the original repository. Since the client sees the
+original git-annex branch, it only knows about the uuid in that branch
+for location tracking.
+
+But using the same uuid would bring in a ton of special cases and problems.
+Just a few of them are:
+* `git-annex get` in the mirror repository would fail to get files from the
+  original repository, because the local repo uuid is filtered out of the
+  remote list in `keyPossibilities'`.
+* The mirror couldn't have its own preferred content configuration.
+
+The mirror repository could have the same uuid as the original set in
+annex.uuid, so the client *thinks* it has the same uuid, but actually have
+a different uuid that is configured elsewhere. Make git-annex use that
+other uuid, and with annex.private set, it will never reach the git-annex
+branch.
+
+In the P2P protocol, `AUTH-SUCCESS` includes the server's uuid.
+That would need to be the original repository's uuid, to avoid a
+client thinking it's talking to the wrong repository.
+
+---
+
+Concretely, a mirror could be configured like this:
+
+    git remote add original http://example.com/foo
+    git pull --prune mirror
+    git config annex.mirroring original
+    git config annex.private true
+    git-annex init
+    # that sets annex.uuid to the discovered uuid of original
+    # and it sets annex.mirror-uuid to the repo's true uuid
+    git-annex mirror --from=original # optional
+

+Following is a small patch that makes import from directory, followed by get
+from the sameas rsync work.
+
+Note that, import from rsync followed by get from sameas directory *won't*
+work with this patch. The reason is that directory special remotes support
+importree+exporttree. And even if they are only configured with exporttree,
+they currently verify ContentIdentifiers when retrieiving. And when no
+ContentIdentifier is known, it will fail.
+
+So, applying this patch seems like it would need remotes like directory to
+have a separate implementation of importActions, rather than the current way
+that exportImportActions is used to implement importActions. There are not
+too many remotes that support importtree+exporttree, so maybe that is worth
+doing.
+
+The other limitation of the patch is that import from rsync followed by get
+from sameas directory that is configured with importree+exporttree still
+won't work. And this approach cannot deal with that case.

+It would be useful in some cases to be able to have a local git remote
+that acts as a proxy to other remotes. That is not currently supported.
+See [[!commit f98605bce7ecfa7fd155d501accb2734d3e9a422]].
+
+Supporting this could be as easy as using git-annex-shell on the path of
+the local git remote and speaking P2P protocol to it.
+
+A possible complication with that: In between uses of a local git remote,
+git-annex is careful to flush files and close handles. That is to support
+removable drives, so nothing is lost if one is ejected while git-annex is
+running, and to make it possible to unmount them. If git-annex-shell 
+has to be spun up once per file, and then shut down afterwards, that might
+be quite slow. Possible approaches to deal with that would be a) document
+that a local git remote that acts as a proxy will keep a removable drive in

+This happens because the meaning of a content identifier is dependent on

+generated for a directory special remote with a rsync special remote will
+not work.
+
+So, for the --sameas remote, the content identifier is accessed using

-### 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 in your own words.
+
+I have a directory special remote with importtree=yes for which I have ran a `git annex import` to make the files stored there known to git-annex. The same directory is also available via ssh, so I have added another rsync special remote with importtree=yes and --sameas= the directory remote. The content tracking properly shows that they both have the same keys available. The issue is that get'ing a key from the rsync remote fails with the error message "no content identifier is recorded, unable to retrieve".

+If that would mean checking on every use of the remote, it seems too often.

+git-annex will filter the tree it exports to only the files that are
+configured to be preferred content of the remote. So you could do this:
+
+	git annex wanted android 'include=album/*'
+	git-annex export master --to android
+
+See [[git-annex-preferred-content]] for details about the syntax, but
+basically you can extend that to as many directories as you want, separated by

+
+----
+
+> How do I create a tree that contains the subfolder itself too?
+
+Worth noting that is a general git question really, with several valid
+answers that don't involve git-annex at all. (One easy one is to check out
+a new branch, `git rm` everything except the subfolder, and `git commit`.)
+
+And once you have such a tree stored on a git branch, you can pass that
+branch to `git-annex export`. So that's an option if you don't want to need
+to deal with git-annex's own filtering features.

+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
+git-credential, and I see no reason for them not to, once the web special
+remote does.
+
+Implemented all of the above.

+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

-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.

+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.
+
+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`
+
+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).

+The [termux Android app](https://termux.dev/) includes git-annex in its
+package repository, so installation is easy:
+    
+    pkg install git-annex
+
+## 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 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. 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
+
+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

+### 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

+
+* [[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]]

+
+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

+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
+that they give to a git command. They know that the only git repos that
+they'll be using under `sharedhosting.com` are under foo.sharedhosting.com
+and bar.sharedhosting.com, which are both sites that they control.
+So they  decide to set `http.https://*.sharedhosting.com/.extraheader` to an
+authentication token to use for both. That's a shortcut, but it's fine.
+
+... Until they clone a git-annex repo from elsewhere that has an autoenabled
+ web special remote configured with `urlinclude=https://baz.sharedhosting.com/`,
+which is a site controlled by an attacker, who intercepts the extraheader
+that git-annex sends.
+
+I think that `credential.<url>.*` configs could also be subject to that
+kind of security hole, if a credential helper had a config that contained
+sensitive information. (I guess that even `credential.<url>.username`
+could be considered sensative information by someone.)

+We are testing a local setup with nginx rev proxy upfront of the S3 store with forgejo. Unfortunately data cannot go into forgejo and has to reside on S3 store, with rev proxy providing authentication.

+Credential helper happily provides those credentials:

+
+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. :) )
