Tag multiple branches in git?

由 天涯浪子 提交于 2019-12-10 04:03:12
问题 I have a git repository with two branches; one for code that's used for manufacturing/test and one that's the actual production firmware (they're nearly identical). It's now time to cut a release to send to the manufacturer, so I naturally want to put down some appropriate tags on both branches. But, it seems that git won't let me put the same tag name on both branches. If I try to tag the branches individually it tells me the tag already exists when I go to tag the seconds branch. I tried

Does a branch misprediction flush the entire pipeline, even for very short if-statement body?

由 不问归期 提交于 2019-12-10 03:26:23
问题 Everything I've read seems to indicate that a branch misprediction always results in the entire pipeline being flushed, which means a lot of wasted cycles. I never hear anyone mention any exceptions for short if-conditions. This seems like it would be really wasteful in some cases. For example, suppose you have a lone if-statement with a very simple body that is compiled down to 1 CPU instruction. The if-clause would be compiled into a conditional jump forward by one instruction. If the CPU

refname is ambiguous and pull failing

由 不羁的心 提交于 2019-12-10 03:17:10
问题 I ran the following command as I wanted to move my production branch back without having to checkout first: git branch -f production HEAD~1 I am now getting the following warning when I checkout production: warning: refname 'production' is ambiguous. I then run: git pull And I receive the following error: First, rewinding head to replay your work on top of it... Fast-forwarded production to 7463e01c536ad52746b8879ef3d70ffd5a8db31e. error: Ref refs/heads/production is at

Xcode 6.0.1 crashes when merging 2 branches

由 笑着哭i 提交于 2019-12-10 03:11:17
问题 Every time I try to merge a branch into another branch Xcode 6.0.1 crashes. So far I have: Tried from a different computer to merge the same branches (pushed them and pulled them before obviously) and it still crashes. Created a new branch from the "faulty branch" added a space in it and merged it back into the "faulty branch" with success. but couldn't merge it into the original branch i wanted to. Whats wrong with Xcode ? How can I merge the branches ? (there are about 100 files to merge)

Git 2.x 中git push时遇到 push.default 警告的解决方法 0.0382016.02.18 20:23:34字数 389阅读 12061 最近在学习使用 git&GitHub，然后今天遇到了一个问题。在执行 git add 和 git commit 操作之后，再进行 git push 操作，出现了如下提示： $ git push warning: push.default is unset; its implicit value has changed in Git 2.0 from 'matching' to 'simple'. To squelch this message and maintain the traditional behavior, use: git config --global push.default matching To squelch this message and adopt the new behavior now, use: git config --global push.default simple When push.default is set to 'matching', git will push local branches to the remote branches that already

Why does git say I am 40 commits ahead when I seem up to date and a push-pull (no files) fixes it?

由 别来无恙 提交于 2019-12-10 02:28:07
问题 I switch to master and it says I am ahead by 40 commits: $ git checkout master Switched to branch 'master' Your branch is ahead of 'origin/master' by 40 commits. But when I then do a pull it says I am up-to-date: $ git pull origin master From https://github.com/dmcouncil/dmWorkflow * branch master -> FETCH_HEAD Already up-to-date. However I can resolve this (remove the 40 commits msg) with: Michaels-MacBook-Pro-2:dmWorkflow durrantm$ git push origin master Everything up-to-date and now the '

how to suggest gcc compiler more probable branch

由 房东的猫 提交于 2019-12-10 02:24:51
问题 Example: if (almost_always_false_condition) { // do something } Is there a way to suggest compiler that in 99% condition will be false. The condition calculation takes ~60 cycles to be checked, and it cannot be calculated at compile time by compiler itself. (gcc 4.3) 回答1: If you want to suggest to GCC that a condition is likely to have a given value as a hint for arranging code flow, you should use __builtin_expect( ) : if (__builtin_expect(almost_always_false_condition,0)) { // do something

Git Release Branch with Squashed Commits

由 帅比萌擦擦* 提交于 2019-12-10 00:23:46
问题 I'm trying to do a similar thing to this: Creating GitHub repository with only a subset of a local repository's history I currently have all my commits on master and now I want to make a branch called release that only has a single commit of all past commits and no history of the old commits. I tried using the method in that link but doing so caused any further merges into release to not merge automatically, which is somewhat annoying. (The error it gives is Squash commit -- not updating HEAD

Combining history of merged branches in GIT?

由 本小妞迷上赌 提交于 2019-12-09 19:42:08
问题 In my git repository, I have merged branch "B" into "master", getting the the following structure: --> A --> B --> C --> D (branch master) | | F --> G --> H (branch B) I now want to combine the branches to get the following history: --> A --> B --> F --> G --> H --> D How can I do this? Regards, Jochen 回答1: I assume C is a merge commit, and that's the reason you don't want to have it in your result. What you need, to do what you want, is git rebase Let's start of with yet another schematic
