[tw5] [TW5] Bob and BobEXE version 1.1.0 Actually Garlic Bagels prerelease

I ended up doing some things on the back-end of Bob that would break
backwards compatibility if anyone modified the server components of Bob. I
am not aware of anyone who has but this gets a minor version bump anyway. I
never got through testing version 1.0.7 before getting distracted so those
changes got rolled into this.

This is a prerelease for now because there have been a lot of changes and
while I am not aware of any new bugs from them, there may be some I have
missed. As always, back up your wikis!! The easiest way is to just make an
archive of your Wikis folder and the IndexWiki.

The big changes from the perspective of using Bob are:
- you can now build html wikis that take tiddlers from any of the wikis
served by Bob instead of just building an html version of an existing wiki.
- You can select which plugins from the server should be used in the
current wiki
- Custom tiddler paths using $:/config/FileSystemPaths should work now

The plugin version of Bob is on GitHub here:
https://github.com/OokTech/TW5-Bob
The newest version of BobEXE is available here:
https://github.com/OokTech/TW5-BobEXE/releases

Here is the current changelog for version 1.1.0

!! Version 1.1.0 (ongoing)

- Add `savePluginFolder` web socket message to save packaged plugins as
folders on a server. These plugins can then be available to other served
wikis and in the plugin library, if it is enabled.
- Add the `import` browser message handler to make fetching nicer
- Add options for how to handle conflicts for `internalFetch`
- `internalFetch` now displays a list of imported tiddlers
- Added a way to change which plugins a wiki uses from inside the wiki
- In the Bob Settings tab there is a Manage Plugins tab
- Added an interface to save plugins to the server and to select which
plugins from the server should be used in the current wiki
- Change the internals to make one $tw.Wiki object for each wiki instead
of having them all in $tw.wiki
- There are lots of internal changes to make this work
- $tw.boot.files still uses the prefixed name
- Streamlined and simplified the file system monitor
- It should now watch new subfolders inside the tiddlers folder
- Environment variables are now set from the plugin, themes, and languages
paths given in the settings.
- This is needed by the core to properly list available plugins
- This means that you can set the location of one folder listing
plugins, themes and languages in the settings instead of using
environment variables. At the moment this is limited to one folder.
- The `unloadWiki` message now ensures that the connection to any browsers
with that wiki open are closed correctly.
- Updates to the `buildHTMLWiki` message
- You can now pull tiddlers in from any served wiki while making an
html file. This means you can combine wikis in the output.
- There is a default filter for excluding plugins like Bob and
components that are only useful on a server
- You can add an additional filter to exclude tiddlers from the exported
html wiki
- You can disable the default exclude list for more control
- The `$:/config/FileSystemPaths` settings should work now

One issue I noticed. The UI for saving plugins doesn't allow you to save
updated versions of plugins. I've a few plugins I regularly update, but
after I added them to the Bob library once, I couldn't update them again.
Is there a reason why adding a plugin twice would result in problems, or is
it just for the UI convience that things already added are removed from the
list? Would it be possible to compare version numbers and allow updating
plugins based on differing numbers?

I think I need more information because I am not sure what you are
referring to here.

If you are trying to save a plugin to the server as part of the plugin
server should check the plugin version number and if the plugin you are
trying to save exists on the server with a newer version than it won't save
it, but never plugin versions should save fine.

I suspect that you imported the plugin into your wiki using drag and drop
and then didn't delete the plugin tiddler after saving it to the server.
Plugin tiddlers in your wiki always override plugins listed in
tiddlywiki.info.

If that is not the case than I need more information before I can say
anything useful.

Ok, so how I'm using Bob is that in the root wiki I'm making all my changes
to my plugin via tinka, and then I'm using Bob's plugin saving feature to
share it with all my other wikis. So, steps to reproduce.

1) Import a plugin into the root wiki for the first time.
2) Save it using the "Manage Plugins" section of Bob Settings. (It shows
up in the drop down next to Save Plugin as Folder)
3) Import it to other wikis as needed via the "Manage Plugins" section of
Bob Settings in the other wikis.
4) Update the plugin in the Root wiki, and repackage via tinka with a
different/higher version number.
5) ??? The plugin does not show up in the drop down box of "Manage Plugins"
and my other wikis are not showing the changes I made to the plugin.

Other information that may be useful. I imported the plugin in the root
wiki, but I'm not selecting it in the "Save Plugin Selection" of the root
wiki.

If there's anything else I can add to help, let me know.

Thanks, Matt

My first thought is that my UI isn't very good. If I remember correctly the
list in the dropdown only shows plugins that are in the wiki but aren't
listed as being on the server but doesn't check the versions. So I believe
that your initial assessment is correct. I made it so that the part that
sends the plugins to the server checks version numbers but I probably
didn't put that on the UI component.

So it is an oversight on my part. Until I get around to finding a way to
fix that you could manually send the updated plugin to the server by making
a copy of the button that has the plugin explicitly listed.

The button code would be something like this (changed the plugin name to
match):

<$button> Save Plugin to Server
<$action-websocketmessage $type='savePluginFolder'
pluginName='$:/plugins/Your/Plugin'/>
</$button>

there may be another bug in how the plugins are saved, if you remove a file
from the plugin it may not be properly removed on the server. So back up
your data!

I need to find out how to solve that in a way that doesn't make it easy to
accidentally delete plugins from the server.

The file actually serves -- but with constant stream of yellow popup error
messages.

Got the same errors when using TW's made by TiddlyDesktop.

Other comments.

Couldn't find a "filepathroot" setting, so assume we have to add it
manually under "manual" ??

Thanks!

So far no luck getting images to serve. But there wasn't an existing
filePathRoot entry, so perhaps I am setting it up wrong?

Ciao Mark

Yeah, you need (1) have the "filePathRoot" set in Manual Settings. Also (2)
optionally "fileURLPrefix". (3) Ensure that the "mimeMap" is active (I
found, 2 Bob versions back, I had to set it manually despite docs saying
they were on by default. I haven't checked if I can remove those manual
settings on the latest).

Here is an example of my settings ...






I wrote a brief note on my broad take on it for managing files for export:
https://groups.google.com/forum/#!msg/tiddlywiki/XsVzEJBDd9Q/6svo1i_BAwAJ

Not being familiar with the node style of serving external files I found
the "virtual"address of "files" initially somewhat confusing. Now I'm a bit
clearer.

Once up and running the serving is robust.

Mark,

It looks like I somehow broke the part that removes the filesystem and
tiddlyweb plugins from served wikis. It looks like all of the errors you
are getting are caused by that. Until I get that fixed one solution is to
remove the tiddlyweb and filesystem plugins from the tiddlywiki.info file.
I will try and fix that later today.

The configuration.md file shows where each configuration property goes and
has a brief description of each one.

Additional note. It's possible for the local network address listed at the
top to be different from the actual port number used by the wsserver at the
bottom of the configuration (mine is 8081 at the top and 8082 in wsserver).

My head's been out of TW for several months so all this Bob stuff is new to
me. Well done Jed and and everyone involved!

But I have a question about a statement on the Multi-User TW5 plugin github
site where you say "*a git plugin is currently being developed*”. I see
this as critical to multi-use TW on the open web and very keen to hear
about its status.

I should explain why.


20 years ago I spent a lot of time on the original c2 wiki. I ran one of
its sister sites, GreenCheese, edited about 2000 pages of the original
WardsWiki, and built the first open source clone of it, “CvWiki". So I saw
most of the heat-death of c2 up close and personal. I was one of the dozen
folk Ward picked as stewards to try to defend it form the trolls 

unsuccessfully 



Right now I'm running the “free and open source agile” community at
http://xscalealliance.org . We have a TW at http://xscale.wiki but most of
our communications are going via slack. I see slack as very inferior to the
wiki way and I’m keen to open up xscale.wiki to multiple users. But given
the broad potential community I think I need git integration to do it.


I had been thinking that we’d just let practitioners use TW's single user
node.js server to edit, and then submit pull requests in the usual git way.
I probably don’t need to tell you that’s clunky 



What I’m hoping for is a multi-user mode where users are able to make a
number of local edits on their local copy of the wiki, then when they press
"save" we would have a pull-request generated automagically along with a
little form for them to fill in the purpose of their edits. After that,
normal github-flow should be sufficient for the community to police its own
development.


Though I think we might also want the “Recents” tab to be improved to
change the river to reflect the recently changed tiddlers. RecentChanges
was the beating pulse of c2 
 to the point that back in the day many of us
made it our browser’s homepage. We called ourselves "RecentChangesJunkies"
...


No worries if you meant something completely different by this but I
thought it might save us a lot of duplicated effort if you’re going down
this path and I'm enormously impressed with the progress you've made on Bob
to date!

Cheers,

Pete

I ended up doing some things on the back-end of Bob that would break
backwards compatibility if anyone modified the server components of Bob. I
am not aware of anyone who has but this gets a minor version bump anyway. I
never got through testing version 1.0.7 before getting distracted so those
changes got rolled into this.
This is a prerelease for now because there have been a lot of changes and
while I am not aware of any new bugs from them, there may be some I have

- Change the internals to make one $tw.Wiki object for each wiki instead
of having them all in $tw.wiki
- There are lots of internal changes to make this work
- $tw.boot.files still uses the prefixed name
- Streamlined and simplified the file system monitor
- It should now watch new subfolders inside the tiddlers folder
- Environment variables are now set from the plugin, themes, and languages
paths given in the settings.
- This is needed by the core to properly list available plugins
- This means that you can set the location of one folder listing
plugins, themes and languages in the settings instead of using
environment variables. At the moment this is limited to one folder.
- The `unloadWiki` message now ensures that the connection to any browsers
with that wiki open are closed correctly.
- Updates to the `buildHTMLWiki` message
- You can now pull tiddlers in from any served wiki while making an
html file. This means you can combine wikis in the output.
- There is a default filter for excluding plugins like Bob and
components that are only useful on a server
- You can add an additional filter to exclude tiddlers from the
exported html wiki
- You can disable the default exclude list for more control
- The `$:/config/FileSystemPaths` settings should work now

By "Virtual" I meant that an image is addressed in a Bob TW tiddler like
this ...

[img[./f/bm/img/Funny-Sheep-Facts.jpg]]

The on disk address of the file is actually ...

C:\bag\PortableApps\twBOB\ext\bm\img\Funny-Sheep-Facts.jpg

The "virtual" bit is the "f" //that doesn't actually exist on disk// we
need in the tiddler. Well that is my current understanding that seems to
work well.

This is exactly what I was looking for yesterday!

Thank you for this precise step-by-step ... I had read the documentation
but didn't "get it" ... this worked perfectly for me!

Mark,
I am not sure what you mean by 'at the top' and 'at the bottom', but there
is a known bug with the port numbers that can happen when you allow it to
auto-increment ports https://github.com/OokTech/TW5-Bob/issues/24
To make images serve you have to set the filePathRoot which is the root
path served by the static file server. The default mime is listed in the
serving files documentation
https://github.com/OokTech/TW5-Bob/blob/master/Documentation/Serving%20Files.tid
but that was just updated to fix some errors, it had an incomplete listing
for the mimeMap and it said the default url prefix was file instead of
files.
And if there isn't a filePathRoot entry than serving files doesn't work,
it has to be enabled by setting a filePathRoot.
I have no idea what 'virtual addresses' are supposed to be, the files are
served in the normal way by a webserver.
1) Download BobEXE for your system (or set up the plugin version, it makes
no difference but this is faster for testing)
2) Start it and open up the root wiki
3) Go to the $:/ControlPanel
4) Go to the Bob Settings tab in the control panel
5) Go to the Manual Settings tab in the Bob Settings tab
6) At the bottom of where the settings are listed click the last + button,
name the key (the smaller text entry field) filePathRoot and give it the
value (the longer text entry field) that is where you have the files you
want to serve (in my case /home/inmysocks/pictures)
7) Click the check button under the text entry fields
8) Click the Update Settings button
9) Under the Server Actions tab click Shutdown Wiki
10) Restart the wiki
11) Make a new tiddler and put in [img[./files/01.jpg]] (assuming you have
a picture called 01.jpg in the folder listed in the filePathRoot)
it does look like there is a bug here where if you do something that saves
the manual settings again it may stop serving files until the server is
restarted again.

I had to add the fileURLPrefix (undocumented) before it would work.

Having to serve images from one location is a bit limiting, when you may
have Wikis in multiple locations.

Mark,

I don't know if this would work for you, but I just created sub-folders
inside the folder I identified as my filePath so that I can keep the images
for a given wiki separate from the others. You just need to make sure you
add the subfolder to the image's address in the tiddler you're putting it
in.

I hope that made sense, and was helpful.

Dear aged ... yes!
I just created sub-folders inside the folder I identified as my filePath
so that I can keep the images for a given wiki separate from the others.
FWIW I suggested elsewhere that it might be a good idea that when you
create a new wiki you can also assign a "files ID" (just two letters that
indicate the sub-directory). I reasoned like this ...

What I am wondering is whether when you create a new Wiki you can be
prompted to define a "shorthand ID" for it to ensure you never forget the
base address you need for files so you don't get in a mess? This comes from
concern some of my wiki have many images associated with them.
Why is setting a "shorthand ID" useful? You can use it as a variable that
is invoked in a Bob script passed to the OS that tells its where to copy
the files from and where to. Also a problem arises if you don't because, if
you change the name of the wiki, it becomes unclear where to find them.
Basically I (personally) think a set shorthand ID could be useful.

@Josiah

You just caused me to see that what I did may not be the 'best' way! I'm
still very new to TW5 and do not yetl always appreciate the future proofing
actions many of you have come to understand.

I did name the sub-folder the current wiki's name ... now I see that should
I ever change the wiki's name in the future, all those links will end up
being broken. NOT A GOOD SCENARIO!

I like your suggestion of using some sort of ID or prefix code to name the
sub-folders. Also, an ID or prefix-code potentially keeps the links
shorter as well, as some of my wiki's names [which is what I used for the
subfolder names] are a little longish at the moment.

Thank you for pointing this out - much easier to fix now than later on down
the line!

Its easy to create subordinate levels within the "files" folder so that
files can be segregated as needed.

Its just slightly problematic on export methodology to create single-file
wiki that exports their specific files to them. This is something I
commented on before but I don't want to lumber Jed's thread with my
personal interests too much.

But having to have all your images in one location, no matter how you divvy

tiddlyserver, your files can be somewhere in respect to your TW location,
no matter where it is. That way you can zip up the contents of a directory
and have all the information that's required to make a complete TW-eco

When someone asks "exactly" I know I need to come to attention :-).

I tend to use
https://github.com/OokTech/TW5-Bob/blob/master/Configuration.md which does

But having to have all your images in one location, no matter how you divvy

I agree. My take is its about making the best of that. I think its a limit
on node derivation?

respect to your TW location, no matter where it is. That way you can zip up
the contents of a directory and have all the information that's required to

I agree. The files "in the other place" is awkward on export from Bob. It
requires clear planning in advance or you can get in a mess. You can't just
press a button and do it auto.

On the other hand Bob scripts can ameliorate the issue somewhat (like quite
easy "copy" via OS from and to). But the "virtual" addressing in the wiki
itself still needs fixing (i.e. "./f/img/fred.jpg" -> "./img/fred.jpg")
when you export to singular.

I don't understand why it needs fileURLPrefix . It means automatically
that any existing media tiddlers you have will have to have their path
names changed.

I have no idea why. All paths to files served right need a path
prefix--that would be redundant for stand alone TW. I guess its something
to do with its node history? The naming is a bit strange. And on export to
single file its kinda the sand in the ointment of an otherwise brilliant
system.

Just thoughts

It looks like the bug isn't caused by any changes to the manual settings,
just to adding a new wiki. There is probably something about how the new
wiki updates the server paths that doesn't play well with the file server
component. This is why I have a separate server component for the online
version.

I have not run into any troubles where I had to set the fireURLPrefix

Oddly enough, I assumed that "Bob documentation" was the actual
documentation.

Bob wouldn't serve images until I added fileURLPrefix. At first I thought
it might be the missing mime type that was the problem, but after
fileURLPrefix I could remove the manual mime types.

Thanks

The reasons are the same as why until 5.1.18 comes out the node version
didn't have a static file server and that the static file server with the
server in 5.1.18 does the same thing:

1) engineers that make things have an obligation to make sure that the
things that they make are safe to use
2) it is a webserver, not a local file. The paths aren't virtual paths or
anything like that, they are urls. A url doesn't necessarily have any
relation to the file system location of what it points to, but it does have
meaning to the server.

The server Bob uses a web server that can serve multiple wikis, when the
server gets a request it has to determine what the url is supposed to point
to, if you don't have a prefix for files than requests to the server can be
ambiguous about if they are supposed to be a served file or a wiki and you
get inconsistent behaviour. When you have inconsistent behaviour is almost
always a security risk.

To prevent Bob from exposing everything on your hard drive to anyone who
wants it there are a number of safeguards. When serving a wiki the wiki has
to be listed in the settings and the tiddlywiki.info file has to exist,
because of how tiddlywiki is structured there is relatively little risk
involved there. There is far more risk when serving arbitrary files off of
your computer. If you are not very careful with it than there are ways to
ask for a file located somewhere like ../../../../.ssh and then get all the
private keys or passwords on a computer.

And furthermore, Because Bob lets you have wikis hosted on paths like
localhost:8080/Wiki1 and localhost:8080/Wiki1/Wiki2 it becomes ambiguous
how to handle something like localhost:8080/Wiki1/foo.jpg, it could be a
wiki called foo.jpg or it could be the file foo.jpg. Exploiting edge cases
like that is one method of gaining unauthorised access to systems.

Putting all the static file serving on localhost:8080/files and using a
defined mimeMap to filter requests helps with those problems.

I don't get what you mean by "a served file or a wiki". Isn't there a world
of difference between the two?

And why couldn't it be the other way around -- have the "file/" prefix
associated with the Wikis, while the served files can have any prefix (but
only served from below the file root path). Having the prefix on the Wiki
name would not cause the consternation that having it on the image path
name.

As it is, the image paths for Bob will be totally incompatible with
standalone, TiddlyDesktop, and tiddlyserver file paths.

Thanks,

The solution would be if Bob used a special path name (virtual path) for
the Wikis, and not for images. That way the two path types could be
distinguished without making Bob incompatible with other uses of TW.

The reasons are the same as why until 5.1.18 comes out the node version
didn't have a static file server and that the static file server with the
Right. I don't have any problem with it per se now I better understand it.
And I'm grateful you keep malicious hackers away. You have that skill & its
good.
The singular issue I have is that node/Bob serving of files involves (1)
(2) the wiki end up with "hard-coded" addresses that don't exist on disk.
Which means (3) you have to manually edit them to adjust if you export to
single file. That is the central issue for me to solve for the kind of wiki
I make, involving quite a lot of images.
Regarding me using the word "virtual". I don't really mind what word is
used actually. But the point was to help users, not familiar with node/Bob
that pathing to external local files do use a "fictive entity" in the path
(needed in the world of Bob/node, but a bit of a drag in any other). *I*
found that hard to grasp. And I think others would too, at first.
Best wishes
Josiah
