ANSWER
Answered 2022-Mar-28 at 14:18This error is harmless in the sense that it does not indicate a broken repository. It is a bug that was introduced in Git 2.35 and that should be fixed in later releases.
The worst that can happen is that git gc does not prune all objects that are referenced from reflogs.
The error is triggered by an invocation of git reflog expire --all that git gc does behind the scenes.
The trigger are empty reflog files in the .git/logs directory structure that were left behind after a branch was deleted. As a workaround you can remove these empty files. This command lets you find them and check their size:
QUESTION
If I run git fetch origin and then git checkout on a series of consecutive commits, I get a relatively small repo directory.
But if I run git fetch origin and then git checkout FETCH_HEAD on the same series of commits, the directory is relatively bloated. Specifically, there seem to be a bunch of large packfiles.
The behavior appears the same whether the commits are all in place at the time of the first fetch or if they are committed immediately before each fetch.
The following examples use a public repo, so you can reproduce the behavior.
Why is the directory size of example 2 so much larger?
Example 1 (small):
...ANSWER
Answered 2022-Mar-25 at 19:08Because each fetch produces its own packfile and one packfile is more efficient than multiple packfiles. A lot more efficient. How?
First, the checkouts are a red herring. They don't affect the size of the .git/ directory.
Second, in the first example only the first git fetch origin does anything. The rest will fetch nothing (unless something changed on origin).
Compression works by finding common long sequences within the data and reducing them to very short sequences. If
long block of legal mumbo jumbo appears dozens of times it could be replaced with a few bytes. But the original long string must still be stored. If there's a single packfile it must only be stored once. If there's multiple packfiles it must be stored multiple times. You are, effectively, storing the whole history of changes up to that point in each packfile.
We can see in the example below that the first packfile is 113M, the second is 161M, the third is 177M, and the final fetch is 209M. The size of the final packfile is roughly equal to the size of the single garbage compacted packfile.
Why do multiple fetches result in multiple packfiles?git fetch is very efficient. It will only fetch objects you not already have. Sending individual object files is inefficient. A smart Git server will send them as a single packfile.
When you do a single git fetch on a fresh repository, Git asks the server for every object. The remote sends it a packfile of every object.
When you do git fetch ABC and then git fetch DEFs, Git tells the server "I already have everything up to ABC, give me all the objects up to DEF", so the server makes a new packfile of everything from ABC to DEF and sends it.
Eventually your repository will do an automatic garbage collection and repack these into a single packfile.
We can reduce the examples. I'm going to use Rails to illustrate because it has clearly defined tags to fetch.

...ANSWER
Answered 2021-Aug-17 at 05:15QUESTION
EDIT [resolved]
based on the answer from Thingamabobs below, the approach simply turns out to be making sure the elements you spawn are allocated to correct parents.
It is worthwhile to create a frame just to hold every scrollable element since you can't move widgets around between parents when using pack/place. So a common parents between all movable elements will give you the freedom to move them around, again just create a holder frame. See the answer and discussion below for more details.
EDIT2
Bryan's answer below has very good info and an alternate approach using just a canvas. The core concepts still stand the same.
original question begins here
The situationSo based on this answer by Bryan, I used this approach to spawn widgets on a scrollable frame (which is basically a Canvas wrapping a frame inside as we know cause Frames don't have scroll attributes).
The widgets in this case are just tk.Buttons which I spawn in a loop using lambda to preserve state. That aspect is completely fine.
Now everything works fine except when I spawn more elements (again just buttons), they seem to be cut off. and I can't seem to scroll down to see the remaining ones. I am only able to scroll upwards only to see empty space.
please see the video below to see what I mean (excuse my horrible color choices, this is for a quick demo)
In the video, there are more elements below template47 but I can not scroll to them. I can scroll upwards but it's just lonely up there. All the names are actually buttons with zero bd and HLthickness.
To begin, my first instinct was to attach a ttk.scrollbar to the canvas+frame, which I did but observed the exact same behavior.
Then I tried to see if i could use .moveTo('1.0') to scroll down to last entry and then since upward scrolling works already, shouldn't have an issue. But this didn't do anything either. Still the elements were cut off, and it obviously messed up upward scrolling too.
I don't think I can use pack/grid geoManagers since as the answer by bryan i linked to above suggests, using place with its in_ arg is the preferred way. If it is possible otherwise, let me know though.
as depicted in the answer linked above, I also have two frames, and I'm using the on_click callback function to switch parents (a lot like in example code in answer). Turned out place was the best bet to achieve this. and it is, all of that aspect is working well. It's just the scroll thingy which doesn't work.
some code (dare i say MCVE)how i bind to mousewheel
...ANSWER
Answered 2021-Dec-27 at 14:37The main issue is that you are using place and with place you will be the allmighty over the widget, means there will be no requested size to the master or any other magic tkinter provides in the background. So I do recommand to use another geometry manager that does that magic for you like pack. Also note that I set the anchor to nw.
In addition it appears that you can only use the optional argument in_ in a common master. So the key of that concept is to have an holder frame that is used as master parameter and use the in_ for children that are able to hold widgets.
QUESTION
I couldn't find a question similar to the one that I have here. I have a very large named list of named vectors that match column names in a dataframe. I would like to use the list of named vectors to replace values in the dataframe columns that match each list element's name. That is, the name of the vector in the list matches the name of the dataframe column and the key-value pair in each vector element will be used to recode the column.
Reprex below:
...ANSWER
Answered 2021-Dec-13 at 04:44One work around would be to use your map2_dfr code, but then bind the columns that are needed to the map2_dfr output. Though you still have to drop the names column.

QUESTION
What are the major differences between S3 lake formation governed tables and databricks delta tables? they look pretty similar.
...ANSWER
Answered 2021-Dec-12 at 19:18Governed tables, Delta Lake, and to some extent also Apache Iceberg and Hudi are all tabular data formats. Instead of storing data solely in raw formats (parquet, orc, avro) tablular formats have additional manifest files which provides metadata about which files are present in a table during a certain state. This allows them all to enable features like ACID transactions, time-travel, and snapshotting. The main difference right now is which big data tools they can integrate with.
AWS Governed tables is a Lake Formation offering and thus lets you govern access of data catalog objects (database, table, and column) through the Lake Formation permission model. It also offers integration with AWS query engines: Redshift Spectrum, Glue, and Athena. EMR Spark is not yet supported. It also provides ACID transactions, time traveling, and snapshotting.
Delta Lakes provides ACID transactions, time traveling, and snapshotting on Spark. It also supports Spark streaming and data mutation.
