How To Clean Up The Git Repo And Reduce Its Disk Size

Create and manage workspaces in Bitbucket Cloud A workspace contains projects and repositories. Learn how to create a workspace, control access, and more.Set up and work on repositories in Bitbucket Cloud Whether you have no files or many, you'll want to create a repository. These topics will teach you everything about repositories.Build, test, and deploy with Pipelines Pipelines is an integrated CI/CD service built into Bitbucket. In your user folder in Databricks Repos, clone your remote repository.

A best practice is to create a new feature branch, or select a previously created branch, for your work, instead of directly committing and pushing changes to the main branch. You can make changes, commit, and push changes in that branch. When you are ready to merge your code, create a pull request and follow the review and merge processes in Git. Now it was originally build to kill history so it can actually delete files, like obliterate files, from your history or entire folders or even strings within files. The git tag action allows a user to apply a tag to the git repository in the workspace based on the git commit used in the build applying the tag. The git plugin does not push the applied tag to any other location.

How to clean up the git repo and reduce its disk size - Learn how to create a workspace

If the workspace is removed, the tag that was applied is lost. Tagging a workspace made sense when using centralized repositories that automatically applied the tag to the centralized repository. Applying a git tag in an agent workspace doesn't have many practical uses. So that's how you can use the BFG to rewrite your history.

How to clean up the git repo and reduce its disk size - These topics will teach you everything about repositories

But this kind of question that you get to, particularly with big repositories or repositories that have very long histories and that is which files should I be tracking with LFS. And what Repofactor does is it helps you identify large blob chains sitting inside your repository. Then it calculates the average size of that blob over time. And this is really good cause that size is sort of a function of how well that file compresses. So, first of all to understand why Git has such a hard time with large binaries you need to know a little bit about the Git data model. Now when you think about the changes to a code base over time, as it relates to version control, you're probably thinking about a set of revisions or commits.

How to clean up the git repo and reduce its disk size - In your user folder in Databricks Repos

Now in Git, these revisions, actually they're called commits in Git, these commits don't just float in space. Specifically each commit has a reference to its immediate parent or parents in the case of a merge commit. Now if we put in branches or tags, more commonly known as refs in Git parlance, you start to get a picture of what the Git data model looks like. Now this data structure is known as a DAG, or a Directed Acyclic Graph. Basically each node represents a commit, or as we'll see in a second, another object sitting inside your Git data store. And it's directed because each object references another object that was created at some point in time before it.

How to clean up the git repo and reduce its disk size - A best practice is to create a new feature branch

The A in DAG stands for acyclic because each of these objects is immutable. When you create a new object, it refers to an object that already exists. So you can never create a cycle inside this data structure.

How to clean up the git repo and reduce its disk size - You can make changes

With my Vulkan C++ example github repository approaching 200 MB in size I decided it was about time to shrink it down to a reasonable size again. So you can add and stage and commit files and it will actually do all the Git LFS invocations under the hood for you. And also does like a binary previews like the image diffing that we saw before in Bitbucket and reads through automatically to your backend Git LFS store. Rebase before push Some Jenkins jobs may be blocked from pushing changes to the remote repository because the remote repository has received new commits since the start of the job.

How to clean up the git repo and reduce its disk size - When you are ready to merge your code

This may happen with projects that receive many commits or with projects that have long running jobs. The Rebase before push option fetches the most recent commits from the remote repository, applies local changes over the most recent commits, then pushes the result. The plugin uses git rebase to apply the local changes over the most recent remote changes. Clean the workspace before every checkout by deleting all untracked files and directories, including those which are specified in .gitignore.

How to clean up the git repo and reduce its disk size - Now it was originally build to kill history so it can actually delete files

Ensures that the workspace is in the same state as if cloned and checkout were performed in a new workspace. Reduces the risk that current build will be affected by files generated by prior builds. Does not remove files in the .git repository of the workspace. Clean the workspace after every checkout by deleting all untracked files and directories, including those which are specified in .gitignore. Ensures that the workspace is in the same state as if clone and checkout were performed in a new workspace.

Shallow clone Perform a shallow clone by requesting a limited number of commits from the tip of the requested branch. Git will not download the complete history of the project. This can save time and disk space when you just want to access the latest version of a repository. There's this awesome tool called the BFG Repo-Cleaner. It's by a developer who works at The Guardian called Roberto Tyley.

How to clean up the git repo and reduce its disk size - The git plugin does not push the applied tag to any other location

Now Roberto, when he initially built this tool, had a problem. A developer had accidentally committed something sensitive to an earlier version of a properties file sitting in his repo. And this was a problem because to remove that he'd have to go back and basically, you know, run filter branch and eviscerate that from history. And now filter branch is awesome but it's kind of the swiss army knife of repository history rewriting. But it is also pretty intimidating to use and it can be extremely slow. Now one of the things about Git is that at the end of the day, it's a collection of bash scripts and underlying other commands written in C.

How to clean up the git repo and reduce its disk size - If the workspace is removed

So filter branch typically actually walks your entire DAG and reprocesses the same objects and trees over and over again. So when you run git push, those large files get transferred to a separate storage and your Git DAG gets transferred to your Git repository as normal. Then, and this is where the magic happens, when a developer does a clone, or a fetch, or a pull, that DAG is transferred back down to that developer's computer.

How to clean up the git repo and reduce its disk size - Tagging a workspace made sense when using centralized repositories that automatically applied the tag to the centralized repository

So you don't get every single version of these large files in your history. Update new tag Modify existing tag in the workspace so that it points to the most recent commit. Many git repository hosting services will reject attempts to push a tag which has been modified to point to a different commit than its original commit.

How to clean up the git repo and reduce its disk size - Applying a git tag in an agent workspace doesnt have many practical uses

Refer to force push for an option which may force the remote repository to accept a modified tag. The git documentation strongly advises against updating tags. The Jenkins git plugin provides a "git publisher" as a post-build action. The git publisher can push commits or tags from the workspace of a Freestyle project to the remote repository.

How to clean up the git repo and reduce its disk size - So thats how you can use the BFG to rewrite your history

Honor refspec on initial clone Perform initial clone using the refspec defined for the repository. This can save time, data transfer and disk space when you only need to access the references specified by the refspec. If this is not enabled, then the plugin default refspec includes all remote branches. I did the steps as @monfresh suggested and recovered a lot of space on my local machine.

How to clean up the git repo and reduce its disk size - But this kind of question that you get to

But how can I integrate the changes with the remote on github.com? When I try to push new commits, it says the remote contains that I don't have locally. So I did git pull, but now my local repository is back to its original size before cleaning up. Deleting files in a commit doesn't actually reduce the size of the repository, because the earlier commits and blobs still exist.

How to clean up the git repo and reduce its disk size - And what Repofactor does is it helps you identify large blob chains sitting inside your repository

We recommend the open-source community-maintained toolgit filter-repo. Deleting files in a commit doesn't actually reduce the size of the repository, because the earlier commits and blobs still exist. Performance tests are conducted using specific computer systems and reflect the approximate performance of MacBook Pro. So as you have large binaries, the repository bloats and bloats and bloats.

How to clean up the git repo and reduce its disk size - Then it calculates the average size of that blob over time

But with Git, it's a distributed version control system. So you're actually copying around the entire history of your repository every time you need to do a push or a pull or a clone. So that means that I'm pushing every single version of this file that I've touched up to the server and the rest of my team has to pull down every single version of that file. And now the next thing that this commit object has is a tree.

How to clean up the git repo and reduce its disk size - And this is really good cause that size is sort of a function of how well that file compresses

And the tree is analogous to the root level directory that's being tracked by this Git repository. So we'll see in a second but that tree actually contains references to every single object, or file, that's being tracked in our Git repo. But for most commits, this is basically all you're going to see. Additionally, the first time you access a repo after Files in Repos is enabled, you must open the Git dialog. A dialog appears indicating that you must perform a pull operation to sync non-notebook files in the repo.

How to clean up the git repo and reduce its disk size - So

If there are any merge conflicts, another dialog appears giving you the option of discarding your conflicting changes or pushing your changes to a new branch. The important thing to notice is that we have a copy of every blob atHEADbut the blobs in the history are not present. If your repository has a deep history full of large blobs, then this option can significantly reduce yourgit clonetimes.

How to clean up the git repo and reduce its disk size - Now when you think about the changes to a code base over time

The commit and tree data is still present, so any subsequentgit checkoutonly needs to download the missing blobs. The Git client knows how to batch these requests to ask the server only for the missing blobs. Git LFS makes use of a method calledlazy pull and fetchfor downloading the files and their different versions.

How to clean up the git repo and reduce its disk size - Now in Git

By default, these files and their history are not downloaded every time someone clones the repository—only the version relevant to the commit being checked out is downloaded. This makes it easy to keep your repository at a manageable size and improves pull and fetch time. May also update ancillary indexes such as the commit-graph.

How to clean up the git repo and reduce its disk size - Specifically each commit has a reference to its immediate parent or parents in the case of a merge commit

For the huge repositories that have lots of binary cruft committed by mistake, or old assets not needed anymore, a great solution is to usegit filter-branch. The command lets you walk through the entire history of the project filtering out, modifying, and skipping files according to predefined patterns. This feature requires git to be installed on the host where you run the docker build command.

How Do I Fix Bad Soil In My Lawn

Before seeding or sodding, it's important to thoroughly work the soil. Amend poor soils, such as heavy clay, by adding organic matter. Sources include compost, rotted manure, peat, and quality topsoil. Sand is not suggested as a material to improve clay soils for home lawns. At the opposite end of the scale from sandy soil are clay soils.

how do i fix bad soil in my lawn - Before seeding or sodding

These hold water and nutrients very well but don't drain as well as sandy soils, especially if compacted, a common situation for lawns with a clay soil base. This nutrient-rich material serves to moderate the hardness of the mineral component. When the soil is predominantly clay or sand, the addition of organic matter makes clay soil looser, and easier to work.

how do i fix bad soil in my lawn - Amend poor soils

In clay soils, organic matter additions improve drainage, and allow air to move into the soil more readily. In sandy soil, it helps to hold moisture and nutrients in the root zone of the lawn. Organic matter has the magical quality of being able to help both soil problems. If you want to know what it looks like, buy a bag of compost at a garden center.

how do i fix bad soil in my lawn - Sources include compost

High-quality composts are predominantly organic matter. Gypsum is easily applied to the soil surface with a regular lawn spreader. It's an ideal amendment for improving soil structure and relieving compaction in existing lawns and gardens. When planting trees and shrubs, always dig generous planting holes shallow and wide. The hole should be at least twice the width of the root ball or the container in which the plant is growing and no deeper than the root ball of the tree or shrub to be planted. Soil loosened below the root ball will settle over time, creating a planting depression that will accumulate excess water.

how do i fix bad soil in my lawn - Sand is not suggested as a material to improve clay soils for home lawns

In heavy clay soils, planting trees and shrubs a few inches above the grade of the surrounding soil is preferrable. In extreme cases, mound planting is preferable, as it can help with root development above existing compacted soil. These products lack the nutrients and microorganisms present in compost, but they nevertheless add organic matter and improve heavy soils significantly. A high clay soil holds on to nutrients, stays wet longer, and is slow to warm up and dry off in spring.

how do i fix bad soil in my lawn - At the opposite end of the scale from sandy soil are clay soils

These soils are slimey and can be formed in your hand when wet. Avoid working high clay soils when wet – this leads to compaction. Clay soils are made of extremely small particles that are packed close together.

how do i fix bad soil in my lawn - These hold water and nutrients very well but dont drain as well as sandy soils

How Do You Fix Bad Soil When lawns growing on clay soils receive even moderate foot traffic, the particles mash together in what is known as compaction. There is little room for water and air, because the voids are reduced. The limited space tends to fill up with water after a rainfall, leaving little or no oxygen for the root system.

How Do You Fix Bad Soil

Water does not pass quickly through clay soils, and often will move downward only after the soil voids are completely saturated. Clay's potential as one of the best soil types for plant growth lies in its unique properties. Managed well, clay soil typically requires less irrigation and less fertilizer, and leads to healthier plants all around. In addition to incorporation into the soil, applying organic matter as mulch is beneficial for many flowers, vegetables, trees and shrubs. Top-dressing of lawns may be done with good topsoil or topsoil–organic material combinations to smooth out irregular areas in the lawn or help decay thatch. Adding a few inches of topsoil does not generally improve the texture or performance of heavy clay and poorly drained soils unless it is done in combination with core aerification.

how do i fix bad soil in my lawn - When the soil is predominantly clay or sand

Compaction is most likely to occur with heavier soils like clay and loam, but when heavy equipment is used, sandy soils can become compacted. These are soil particles that are packed closely together. The problem may be compounded by events that have happened to the soil over the course of years. The pore spaces are reduced to the point that air and water cannot move freely and plant roots cannot grow easily into the surrounding soil. The soil could remain overly wet longer than is healthy for the plants growing there. The tasks are listed here in the order in which they'd be done, in an ideal world.

how do i fix bad soil in my lawn - In clay soils

Since it's not an ideal world, you'll probably need to be selective. Say it's fall and you've got an okay lawn without serious bare spots, weed patches, or thatch. Skip de-thatching and weeding, and instead aerate thoroughly , and topdress with a mixture of compost and corn gluten meal. The compost, a soil amendment, will help improve soil structure, as does aerating, and the corn gluten will both fertilize the grass and kill new weed seeds.

how do i fix bad soil in my lawn - In sandy soil

Ideal soils for lawns have a loose structure to allow water, air, and nutrients to penetrate through them. Soil that contains too much clay will pack down, making it difficult for the plants to spread their roots and access much-needed moisture. Soil that contains too much sand becomes very loose and allows too much water to flow through, without allowing the plants time to absorb the moisture. Unlike manufactured fertilizers, organic matter releases nutrients slowly into the soil, keep it nourished for long periods of time. A good lawn soil also includes an element that aids with moisture retention and keeps the plants well hydrated.

how do i fix bad soil in my lawn - Organic matter has the magical quality of being able to help both soil problems

For centuries people have been adding things to poor soils to improve their ability to support healthy plant growth. Some of these materials, such as compost, clay and peat, are still used extensively today. Many soil amendments also add nutrients such as carbon and nitrogen, as well as beneficial bacteria. Additional nutrients, such as calcium, magnesium and phosphorus, may be augmented by amendments as well.

how do i fix bad soil in my lawn - If you want to know what it looks like

This enriches the soil, allowing plants to grow bigger and stronger. Many patchy lawns suffer from compacted soil, which deprives grass roots of needed oxygen. Removing plugs of soil with a core aerator allows air and water to penetrate the ground and leaves space for surrounding soil to expand and loosen. Plan ahead and reserve the core aerator for at least half a day for an average-size lawn. You'll need a truck or trailer to haul the core aerator home. The machine weighs 150 to 200 lbs., so it takes some muscle to move around.

how do i fix bad soil in my lawn - High-quality composts are predominantly organic matter

If you're not up to the task, consider hiring a lawn service for this part of the job . Allow a day between aerating and seeding to let the soil plugs dry. Dry plugs will break up easier when you blend them in along with the dressing of topsoil. Clay, silty and sandy are three other common soil types and the right combination of them makes up loamy soil. Sandy soil particles are large which causes water and nutrients to drain too quickly out of the soil. When doing your soil jar test, sandy soil will be the first layer to settle at the bottom and should make up 40% of the jar's soil.

how do i fix bad soil in my lawn - Gypsum is easily applied to the soil surface with a regular lawn spreader

Since sandy particles are heavier, you'll begin to see that layer a few minutes after you set the jar down to settle. It's easiest to see all the layers if you mark each layer as they settle. Silt will settle on top of the clay particles and usually looks darker in color. Your silt layer will settle in about 4-5 hours and should make up around 40% of your soil. Clay soil has tiny particles which creates poor drainage in the soil if you have too much of it. Since clay particles are the smallest of the three soil types in your jar test you'll see the layer on top.

You should also have some trace amounts of organic matter floating just over the clay layer or at the top of your jar. Amending the soil used to backfill planting holes provides questionable benefits. If any soil amendment is done in the planting hole, provide for a gradual transition of soil types .

how do i fix bad soil in my lawn - When planting trees and shrubs

If the backfill soil is drastically different from the existing soil, roots will not readily penetrate the soil around the planting hole. Significant textural differences in soil can also affect soil water movement. If the container growing mix is high in peat and the surrounding soil is clay, water will tend to move out of the root ball. Excessively wet root zones may result when the tree's or shrub's root ball is high in clay content and the backfill soil contains a high level of organic matter. The most common use of soil amendments is to improve soil structure. Soil compaction impedes root growth, decreasing the ability of plants to take up nutrients and water.

how do i fix bad soil in my lawn - The hole should be at least twice the width of the root ball or the container in which the plant is growing and no deeper than the root ball of the tree or shrub to be planted

Soil amendments can add more loft and texture to keep the soil loose. Next, gently squeeze the ball to lengthen it into a strip or 'ribbon' and see how long you can make it before it starts to break up. The more clay it contains, the longer the ribbon will get and the more plastic it will feel to the touch. Soil ribbons can range in length from about 5mm – 75mm, with sandy soils being shortest, loamy soils in the middle and clay soils the longest. While soils that contain a lot of clay or sand may need work to improve them, loamy soils are generally ideal.

how do i fix bad soil in my lawn - Soil loosened below the root ball will settle over time

These contain a mixture of sand, silt, organic matter and clay, providing the right balance of nutrients, oxygen, water and drainage which are just what your lawn needs. Use the back side of a grader rake to filter the soil through the lattice holes.. Now the compost or amended soil left behind on the grass May be 1/2 inch or more where there are uneven ground. Since only 50% of the ground is covered use the backside of the rake again to spread the layer of soil. Apply granulated powders lime with hand as it is difficult with a spreader as it is dense.PH value and fertilizer effectiveness will be immediately enhanced. You cannot over lime but be generous it's cheap., this is much like putting A nice black pepper on your meal.

Your body will absorb the nutrients considerably better. Adding organic matter to the soil improves the soil's structure, aeration, water- and nutrient-holding capacity, root penetration and workability. If you're noticing puddles of water in your garden, it may be time for some new topsoil. Drainage issues often occur when soil is densely packed, and water is unable to seep down into the soil.

how do i fix bad soil in my lawn - In extreme cases

To improve drainage, add a sandy topsoil to the affected area. Till the new and old soils together until it's about 12 inches deep. This will help break up the packed soil and improve circulation and drainage around the roots of your plants. Unfortunately, there is no quick fix to change clay into perfect soil. What we focus on is changing the soil structure, rather than try to change the type of soil.

how do i fix bad soil in my lawn - These products lack the nutrients and microorganisms present in compost

You improve the soil structure by breaking up the compacted clay and adding organic material. This gives the clay something useful to bind to, and it is a material that combats every problem that clay causes. The organic material will improve drainage, resist compaction, and both holds and releases nutrients and water. Breaks apart clay bonds to create microscopic air space deep into the clay.

how do i fix bad soil in my lawn - A high clay soil holds on to nutrients

It also adds liquid organic matter to help generate and feed beneficial soil microbes of all types at the same time. It helps improve drainage in your lawn clay, encourages deeper rooting, frees up nutrients and water in the root zone and helps move organic matter deeper into the soil. By improving clay conditions you can create a much healthier lawn in a more bioactive soil. Before you return the sod to its place, turn it upside down, and get all the weed roots, or you'll just be replanting weeds.

how do i fix bad soil in my lawn - These soils are slimey and can be formed in your hand when wet

It's okay to loosen and even remove soil from around the grass roots as you do this. Yes, it puts some stress on the grass, but leaving major weeds in place will stress it more. Once the sod and loosened dirt is weed-free, return first the dirt, then the sod to the ground. Keep the area well-watered for a couple of weeks while the roots re-establish themselves.

how do i fix bad soil in my lawn - Avoid working high clay soils when wet  this leads to compaction

The best sandy soil amendments are ones that increase the ability of the sandy soil to retain water and increase the nutrients in the soil as well. Sandy soils can usually benefit from the addition of organic material, such as well rotted manure or compost which will help the soil to retain both moisture and nutrients. Incorporating 2 inches of organic material into the top 6 inches of the soil before seeding will significantly improve the texture of soils with a high sand content. Soils with a high composition of sand barely hold together and feel gritty.

how do i fix bad soil in my lawn - Clay soils are made of extremely small particles that are packed close together

The larger particles create pores for water and nutirents to move through quickly. They tend to be nutirent deficient, fast draining and dry. High sand soils will need watering and fertilizing more often. Sandy soils are very well drained, and sometimes excessively so. The angular shape of the particles creates lots of air space so that water passes through the soil quickly. In general, roots thrive in sandy soils, because they get the oxygen they need to grow well.

how do i fix bad soil in my lawn - When lawns growing on clay soils receive even moderate foot traffic

Another advantage is that sandy soils hold their shape well, and resist compaction. Golf course greens and professional sports fields are heavily sand based. They require compaction resistance and rapid drainage to maintain a firm, safe playing surface.

how do i fix bad soil in my lawn - There is little room for water and air

Turf, like other garden plants, depends on healthy soil to thrive. By applying pelletized compost and a slow-release organic fertilizer, you will encourage grass roots to penetrate deeper into the soil, and will also stimulate biological activity. Healthy, biologically-active soil has the texture and trace nutrients plants need to resist stress, disease and insect damage. If you live in the northern half of the U.S., early fall is the best time to fertilize.

how do i fix bad soil in my lawn - The limited space tends to fill up with water after a rainfall

This gives cool-climate grasses time to "beef up" before winter. These grasses should be fertilized lightly, several times between early spring and late summer. Foot traffic and lawn machinery can compact the soil under your lawn, creating a difficult environment for grass roots and soil microbes.

how do i fix bad soil in my lawn - Water does not pass quickly through clay soils

Air passages in the soil are necessary in order for water, air and nutrients to move down into the root zone. To loosen hard, compacted soil, you can use a hand-held or machine-powered aerator to remove small cores of soil. You can also strap on a pair of aerator sandals and walk around your yard. Spikes on the bottom of the sandals create tiny passageways for air and water.
