You've just created a new branch called "blue" with the blue +content. Be aware this topic is not updated against the **current** next branch. +,-) + + + +Very detailed version +===================== + +I started reading over the SubmittingPatches document for Git, primarily because +I wanted to have a document similar to it for OfflineIMAP to make sure people +understand what they are doing when they write `Signed-off-by` line. + +But the patch submission requirements are a lot more relaxed here on the +technical/contents front, because the OfflineIMAP is a lot smaller ;-). So here +are only the relevant bits. + + +Decide what branch to base your work on +--------------------------------------- + +In general, base your work on the ``next`` branch. Otherwise, start off of the +latest commit your change is relevant to. + + +Make separate commits for logically separate changes +---------------------------------------------------- + +Unless your patch is really trivial, you should not be sending your +changes in a single patch. Instead, always make a commit with +complete commit message and generate a series of small patches from +your repository. + +Describe the technical detail of the change(s). + +If your description starts to get too long, that's a sign that you probably need +to split up your commit to finer grained pieces. That being said, patches which +plainly describe the things that help reviewers check the patch, and future +maintainers understand the code, are the most beautiful patches. + +Descriptions that summarise the point in the subject well, and describe the +motivation for the change, the approach taken by the change, and if relevant how +this differs substantially from the prior version, can be found on Usenet +archives back into the late 80's. Consider it like good Netiquette, but for +code. + + +Generate your patch using git tools out of your commits +------------------------------------------------------- + +* ``git`` based diff tools (git, Cogito, and StGIT included) generate *unidiff* +which is the preferred format. + +* You do not have to be afraid to use ``-M`` option to ``git diff`` or ``git +format-patch``, if your patch involves file renames. The receiving end can +handle them just fine. + +* Please make sure your patch does not include any extra files which do not +belong in a patch submission. + +* Make sure to review your patch after generating it, to ensure accuracy. + +* Before sending out, please make sure it cleanly applies to the ``next`` branch +head. If you are preparing a work based on somewhere else, that is fine, but +please mark it as such. + + +Sending your patches +-------------------- + +The mailing list is the preferred way for sending patches. This allows easier +review and comments on the code. + +People on the mailing list need to be able to read and +comment on the changes you are submitting. It is important for +a developer to be able to "quote" your changes, using standard +e-mail tools, so that they may comment on specific portions of +your code. For this reason, all patches should be submitted +"inline". WARNING: Be wary of your MUAs word-wrap +corrupting your patch. Do not cut-n-paste your patch; you can +lose tabs that way if you are not careful. + +It is a common convention to prefix your subject line with +[PATCH]. This lets people easily distinguish patches from other +e-mail discussions. Use of additional markers after PATCH and +the closing bracket to mark the nature of the patch is also +encouraged. E.g. [PATCH/RFC] is often used when the patch is +not ready to be applied but it is for discussion, [PATCH v2], +[PATCH v3] etc. are often seen when you are sending an update to +what you have previously sent. + +* ``git format-patch`` command follows the best current practice to + format the body of an e-mail message. At the beginning of the + patch should come your commit message, ending with the + ``Signed-off-by:`` lines, a line that consists of three dashes, + followed by the diffstat information and the patch itself. + +* If you are forwarding a patch from somebody else, optionally, at + the beginning of the e-mail message just before the commit + message starts, you can put a ``From:`` line to name that person. + +* You often want to add additional explanation about the patch, + other than the commit message itself. Place such "cover letter" + material between the three dash lines and the diffstat. + +* Do not attach the patch as a MIME attachment, compressed or not. + Many popular e-mail applications will not always + transmit a MIME attachment as plain text, making it impossible to comment on + your code. A MIME attachment also takes a bit more time to process. This does + not decrease the likelihood of your MIME-attached change being accepted, but it + makes it more likely that it will be postponed. + + Exception: If your mailer is mangling patches then someone may ask + you to re-send them using MIME, that is OK. + +* Do not let your e-mail client send quoted-printable. + +* Do not let your e-mail client send format=flowed which would destroy +whitespaces in your patches. + +* Do not PGP sign your patch, at least for now. Most likely, your + maintainer or other people on the list would not have your PGP + key and would not bother obtaining it anyway. Your patch is not + judged by who you are; a good patch from an unknown origin has a + far better chance of being accepted than a patch from a known, + respected origin that is done poorly or does incorrect things. + + If you really really really really want to do a PGP signed + patch, format it as "multipart/signed", not a text/plain message + that starts with '-----BEGIN PGP SIGNED MESSAGE-----'. That is + not a text/plain, it's something else. + +* Unless your patch is a very trivial and an obviously correct one, + first send it with "To:" set to the mailing list, with "cc:" listing + people who are involved in the area you are touching (the output from + "git blame $path" and "git shortlog --no-merges $path" would help to + identify them), to solicit comments and reviews. After the list + reached a consensus that it is a good idea to apply the patch, re-send + it with "To:" set to the maintainer and optionally "cc:" the list for + inclusion.

One approach is to configure + Thunderbird to not mangle patches. The second approach is to use + an external editor to keep Thunderbird from mangling the patches. + +**Approach #1 (configuration):** + + This recipe is current as of Thunderbird 2.0.0.19. Three steps: + + 1. Configure your mail server composition as plain text + Edit...Account Settings...Composition & Addressing, + uncheck 'Compose Messages in HTML'. + 2. Configure your general composition window to not wrap + Edit..Preferences..Composition, wrap plain text messages at 0 + 3. Disable the use of format=flowed + Edit..Preferences..Advanced..Config Editor. Search for: + mailnews.send_plaintext_flowed + toggle it to make sure it is set to 'false'. + + After that is done, you should be able to compose email as you + otherwise would (cut + paste, git-format-patch | git-imap-send, etc), + and the patches should not be mangled. + +**Approach #2 (external editor):** + +This recipe appears to work with the current [*1*] Thunderbird from Suse. + +The following Thunderbird extensions are needed: + AboutConfig 0.5 + http://aboutconfig.mozdev.org/ + External Editor 0.7.2 + http://globs.org/articles.php?lng=en&pg=8 + + +1) Prepare the patch as a text file using your method of choice. + +2) Before opening a compose window, use Edit->Account Settings to + uncheck the "Compose messages in HTML format" setting in the + "Composition & Addressing" panel of the account to be used to send the + patch. [*2*] + +3) In the main Thunderbird window, _before_ you open the compose window + for the patch, use Tools->about:config to set the following to the + indicated values:: + + mailnews.send_plaintext_flowed => false + mailnews.wraplength => 0 + +4) Open a compose window and click the external editor icon. + +5) In the external editor window, read in the patch file and exit the + editor normally. + +6) Back in the compose window: Add whatever other text you wish to the + message, complete the addressing and subject fields, and press send. + +7) Optionally, undo the about:config/account settings changes made in + steps 2 & 3. + + +[Footnotes] + +*1* Version 1.0 (20041207) from the MozillaThunderbird-1.0-5 rpm of Suse +9.3 professional updates. + +*2* It may be possible to do this with about:config and the following +settings but I haven't tried, yet:: + + mail.html_compose => false + mail.identity.default.compose_html => false + mail.identity.id?.compose_html => false + +(Lukas Sandström) + There is a script in contrib/thunderbird-patch-inline which can help you + include patches with Thunderbird in an easy way. To use it, do the steps above + and then use the script as the external editor. + +Gnus +---- + +'|' in the *Summary* buffer can be used to pipe the current +message to an external program, and this is a handy way to drive +"git am". However, if the message is MIME encoded, what is +piped into the program is the representation you see in your +*Article* buffer after unwrapping MIME. This is often not what +you would want for two reasons. It tends to screw up non ASCII +characters (most notably in people's names), and also +whitespaces (fatal in patches). Running 'C-u g' to display the +message in raw form before using '|' to run the pipe can work +this problem around. + + +KMail +----- + +This should help you to submit patches inline using KMail. + +1) Prepare the patch as a text file. + +2) Click on New Mail. + +3) Go under "Options" in the Composer window and be sure that + "Word wrap" is not set. + +4) Use Message -> Insert file... and insert the patch. + +5) Back in the compose window: add whatever other text you wish to the + message, complete the addressing and subject fields, and press send. + + +Gmail +----- + +GMail does not appear to have any way to turn off line wrapping in the web +interface, so this will mangle any emails that you send. You can however +use "git send-email" and send your patches through the GMail SMTP server, or +use any IMAP email client to connect to the google IMAP server and forward +the emails through that. + +To use ``git send-email`` and send your patches through the GMail SMTP server, +edit `~/.gitconfig` to specify your account settings:: + + [sendemail] + smtpencryption = tls + smtpserver = smtp.gmail.com + smtpuser = user@gmail.com + smtppass = p4ssw0rd + smtpserverport = 587 + +Once your commits are ready to be sent to the mailing list, run the +following commands:: + + $ git format-patch --cover-letter -M origin/master -o outgoing/ + $ edit outgoing/0000-* + $ git send-email outgoing/* + +To submit using the IMAP interface, first, edit your `~/.gitconfig` to specify your +account settings:: + + [imap] + folder = "[Gmail]/Drafts" + host = imaps://imap.gmail.com + user = user@gmail.com + pass = p4ssw0rd + port = 993 + sslverify = false + +You might need to instead use: folder = "[Google Mail]/Drafts" if you get an error +that the "Folder doesn't exist". + +Once your commits are ready to be sent to the mailing list, run the +following commands:: + + $ git format-patch --cover-letter -M --stdout origin/master | git imap-send + +Just make sure to disable line wrapping in the email client (GMail web +interface will line wrap no matter what, so you need to use a real +IMAP client). diff --git a/docs/doc-src/HACKING.rst b/docs/doc-src/HACKING.rst deleted file mode 100644 index d4b3001..0000000 --- a/docs/doc-src/HACKING.rst +++ /dev/null @@ -1,792 +0,0 @@ -.. -*- coding: utf-8 -*- -.. _OfflineIMAP: http://offlineimap.org -.. _commits mailing list: http://lists.offlineimap.org/listinfo.cgi/commits-offlineimap.org -.. _mailing list: http://lists.alioth.debian.org/mailman/listinfo/offlineimap-project - -Hacking OfflineIMAP -=================== - -In this section you'll find all the information you need to start -hacking `OfflineIMAP`_.

You will need to know very little about git -to get started. - -For the impatient, see the :ref:`contribution checklist` below. - -Git Branching model --------------------- - -OfflineIMAP uses the following branches: - - * master - * next - * maint - * (pu) - * & several topic oriented feature branches. A topic may consist of - one or more patches. - -master -++++++ - -If you're not sure what branch you should use, this one is for you. -This is the mainline. Simple users should use this branch to follow -OfflineIMAP's evolution. - -Usually, patches submitted to the mailing list should start off of -this branch. - -next -++++ - -Patches recently merged are good candidates for this branch. The content of next -is merged into the mainline (master) at release time for both stable and -rc -releases. - -When patches are sent to the mailing list, contributors discuss about them. Once -done and when patches looks ready for mainline, patches are first merged into -next. Advanced users and testers use this branch to test last merged patches -before they hit the mainline. This helps not introducing strong breackages -directly in master. - -pu -+++ - -pu stands for "proposed updates". If a topic is not ready for master nor next, -it may be merged into pu. This branch only help developers to work on someone -else topic or an earlier pending topic. - -This branch is **not intended to be checkouted**; never. Even developers don't -do that. Due to the way pu is built you can't expect content there to work in -any way... unless you clearly want to run into troubles. - -Developers can extract a topic from this branch to work on it. See the following -section "Extract a topic from pu" in this documentation. - -maint -+++++ - -This is the maintenance branch. It gets its own releases starting from an old -stable release. It helps both users having troubles with last stable releases -and users not wanting latest features or so to still benefit from strong bug -fixes and security fixes. - -Release cycles --------------- - -A typical release cycle works like this: - -1. A stable release is out. - -2. Feature topics are sent, discussed and merged. - -3. When enough work was merged, we start the freeze cycle: the first release - candidate is out. - -4. During the freeze cycle, no more features are merged. It's time to test - OfflineIMAP. New candidates version are released. The more we are late in -rc - releases the less patches are merged but bug fixes. - -5. When we think a release is stable enough, we restart from step 1. - -Tagging release or RC ---------------------- - -It is done via Git's ``tag`` command, but you must do ``git tag -a`` -to create annotated tag. - -Release tags are named ``vX.Y.Z`` and release candidate tags are named -``vX.Y.Z-rcN``. - - -.. _contribution checklist: - - -Contribution Checklist (and a short version for the impatient) -=============================================================== - -Create commits --------------- - -* make commits of logical units -* check for unnecessary whitespace with ``git diff --check`` - before committing -* do not check in commented out code or unneeded files -* the first line of the commit message should be a short - description (50 characters is the soft limit, see DISCUSSION - in git-commit(1)), and should skip the full stop -* the body should provide a meaningful commit message, which: - * uses the imperative, present tense: **change**, - not **changed** or **changes**. - * includes motivation for the change, and contrasts - its implementation with previous behaviour -* add a ``Signed-off-by: Your Name `` line to the - commit message (or just use the option `-s` when committing) - to confirm that you agree to the **Developer's Certificate of Origin** -* make sure that you have tests for the bug you are fixing -* make sure that the test suite passes after your commit - - -Export commits as patches -------------------------- - -* use ``git format-patch -M`` to create the patch -* do not PGP sign your patch -* do not attach your patch, but read in the mail - body, unless you cannot teach your mailer to - leave the formatting of the patch alone. -* be careful doing cut & paste into your mailer, not to - corrupt whitespaces. -* provide additional information (which is unsuitable for - the commit message) between the ``---`` and the diffstat -* if you change, add, or remove a command line option or - make some other user interface change, the associated - documentation should be updated as well. -* if your name is not writable in ASCII, make sure that - you send off a message in the correct encoding. -* send the patch to the `mailing list`_ and the - maintainer (nicolas.s-dev@laposte.net) if (and only if) - the patch is ready for inclusion.

So here -is only the relevant bits. - -Decide what branch to base your work on -+++++++++++++++++++++++++++++++++++++++ - -In general, always base your work on the oldest branch that your -change is relevant to. - -* A bugfix should be based on 'maint' in general. If the bug is not - present in 'maint', base it on 'master'. For a bug that's not yet - in 'master', find the topic that introduces the regression, and - base your work on the tip of the topic. -* A new feature should be based on 'master' in general. If the new - feature depends on a topic that is in 'pu', but not in 'master', - base your work on the tip of that topic. -* Corrections and enhancements to a topic not yet in 'master' should - be based on the tip of that topic. If the topic has not been merged - to 'next', it's alright to add a note to squash minor corrections - into the series. -* In the exceptional case that a new feature depends on several topics - not in 'master', start working on 'next' or 'pu' privately and send - out patches for discussion. Before the final merge, you may have to - wait until some of the dependent topics graduate to 'master', and - rebase your work. - -To find the tip of a topic branch, run ``git log --first-parent -master..pu`` and look for the merge commit. The second parent of this -commit is the tip of the topic branch. - -Make separate commits for logically separate changes -++++++++++++++++++++++++++++++++++++++++++++++++++++ - -Unless your patch is really trivial, you should not be sending your -changes in a single patch. Instead, always make a commit with -complete commit message and generate a series of small patches from -your repository. - -Describe the technical detail of the change(s). - -If your description starts to get too long, that's a sign that you -probably need to split up your commit to finer grained pieces. -That being said, patches which plainly describe the things that -help reviewers check the patch, and future maintainers understand -the code, are the most beautiful patches. Descriptions that summarise -the point in the subject well, and describe the motivation for the -change, the approach taken by the change, and if relevant how this -differs substantially from the prior version, can be found on Usenet -archives back into the late 80's. Consider it like good Netiquette, -but for code. - - -Generate your patch using git tools out of your commits -+++++++++++++++++++++++++++++++++++++++++++++++++++++++ - -git based diff tools (git, Cogito, and StGIT included) generate -unidiff which is the preferred format. - -You do not have to be afraid to use -M option to ``git diff`` or -``git format-patch``, if your patch involves file renames. The -receiving end can handle them just fine. - -Please make sure your patch does not include any extra files -which do not belong in a patch submission. Make sure to review -your patch after generating it, to ensure accuracy. Before -sending out, please make sure it cleanly applies to the "master" -branch head. If you are preparing a work based on "next" branch, -that is fine, but please mark it as such. - - -Sending your patches -++++++++++++++++++++ - -People on the mailing list need to be able to read and -comment on the changes you are submitting. It is important for -a developer to be able to "quote" your changes, using standard -e-mail tools, so that they may comment on specific portions of -your code. For this reason, all patches should be submitted -"inline". WARNING: Be wary of your MUAs word-wrap -corrupting your patch. Do not cut-n-paste your patch; you can -lose tabs that way if you are not careful. - -It is a common convention to prefix your subject line with -[PATCH]. This lets people easily distinguish patches from other -e-mail discussions. Use of additional markers after PATCH and -the closing bracket to mark the nature of the patch is also -encouraged. E.g. [PATCH/RFC] is often used when the patch is -not ready to be applied but it is for discussion, [PATCH v2], -[PATCH v3] etc. are often seen when you are sending an update to -what you have previously sent. - -``git format-patch`` command follows the best current practice to -format the body of an e-mail message. At the beginning of the -patch should come your commit message, ending with the -Signed-off-by: lines, and a line that consists of three dashes, -followed by the diffstat information and the patch itself. If -you are forwarding a patch from somebody else, optionally, at -the beginning of the e-mail message just before the commit -message starts, you can put a "From: " line to name that person. - -You often want to add additional explanation about the patch, -other than the commit message itself. Place such "cover letter" -material between the three dash lines and the diffstat. - -Do not attach the patch as a MIME attachment, compressed or not. -Do not let your e-mail client send quoted-printable. Do not let -your e-mail client send format=flowed which would destroy -whitespaces in your patches. Many -popular e-mail applications will not always transmit a MIME -attachment as plain text, making it impossible to comment on -your code. A MIME attachment also takes a bit more time to -process. This does not decrease the likelihood of your -MIME-attached change being accepted, but it makes it more likely -that it will be postponed. - -Exception: If your mailer is mangling patches then someone may ask -you to re-send them using MIME, that is OK. - -Do not PGP sign your patch, at least for now. Most likely, your -maintainer or other people on the list would not have your PGP -key and would not bother obtaining it anyway. Your patch is not -judged by who you are; a good patch from an unknown origin has a -far better chance of being accepted than a patch from a known, -respected origin that is done poorly or does incorrect things. - -If you really really really really want to do a PGP signed -patch, format it as "multipart/signed", not a text/plain message -that starts with '-----BEGIN PGP SIGNED MESSAGE-----'. That is -not a text/plain, it's something else. - -Unless your patch is a very trivial and an obviously correct one, -first send it with "To:" set to the mailing list, with "cc:" listing -people who are involved in the area you are touching (the output from -"git blame $path" and "git shortlog --no-merges $path" would help to -identify them), to solicit comments and reviews. After the list -reached a consensus that it is a good idea to apply the patch, re-send -it with "To:" set to the maintainer and optionally "cc:" the list for -inclusion. Do not forget to add trailers such as "Acked-by:", -"Reviewed-by:" and "Tested-by:" after your "Signed-off-by:" line as -necessary. - - -Sign your work -++++++++++++++ - -To improve tracking of who did what, we've borrowed the -"sign-off" procedure from the Linux kernel project on patches -that are being emailed around. Although OfflineIMAP is a lot -smaller project it is a good discipline to follow it. - -The sign-off is a simple line at the end of the explanation for -the patch, which **certifies that you wrote it or otherwise have -the right to pass it on as a open-source patch**. The rules are -pretty simple: if you can certify the below: - -**Developer's Certificate of Origin 1.1** -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - - By making a contribution to this project, I certify that: - - (a) The contribution was created in whole or in part by me and I - have the right to submit it under the open source license - indicated in the file; or - - (b) The contribution is based upon previous work that, to the best - of my knowledge, is covered under an appropriate open source - license and I have the right under that license to submit that - work with modifications, whether created in whole or in part - by me, under the same open source license (unless I am - permitted to submit under a different license), as indicated - in the file; or - - (c) The contribution was provided directly to me by some other - person who certified (a), (b) or (c) and I have not modified - it. - - (d) I understand and agree that this project and the contribution - are public and that a record of the contribution (including all - personal information I submit with it, including my sign-off) is - maintained indefinitely and may be redistributed consistent with - this project or the open source license(s) involved. - -then you just add a line saying - - Signed-off-by: Random J Developer - -This line can be automatically added by git if you run the git-commit -command with the -s option. - -Notice that you can place your own Signed-off-by: line when -forwarding somebody else's patch with the above rules for -D-C-O.

One approach is to configure - Thunderbird to not mangle patches. The second approach is to use - an external editor to keep Thunderbird from mangling the patches. - -**Approach #1 (configuration):** - - This recipe is current as of Thunderbird 2.0.0.19. Three steps: - - 1. Configure your mail server composition as plain text - Edit...Account Settings...Composition & Addressing, - uncheck 'Compose Messages in HTML'. - 2. Configure your general composition window to not wrap - Edit..Preferences..Composition, wrap plain text messages at 0 - 3. Disable the use of format=flowed - Edit..Preferences..Advanced..Config Editor. Search for: - mailnews.send_plaintext_flowed - toggle it to make sure it is set to 'false'. - - After that is done, you should be able to compose email as you - otherwise would (cut + paste, git-format-patch | git-imap-send, etc), - and the patches should not be mangled. - -**Approach #2 (external editor):** - -This recipe appears to work with the current [*1*] Thunderbird from Suse. - -The following Thunderbird extensions are needed: - AboutConfig 0.5 - http://aboutconfig.mozdev.org/ - External Editor 0.7.2 - http://globs.org/articles.php?lng=en&pg=8 - - -1) Prepare the patch as a text file using your method of choice. - -2) Before opening a compose window, use Edit->Account Settings to - uncheck the "Compose messages in HTML format" setting in the - "Composition & Addressing" panel of the account to be used to send the - patch. [*2*] - -3) In the main Thunderbird window, _before_ you open the compose window - for the patch, use Tools->about:config to set the following to the - indicated values:: - - mailnews.send_plaintext_flowed => false - mailnews.wraplength => 0 - -4) Open a compose window and click the external editor icon. - -5) In the external editor window, read in the patch file and exit the - editor normally. - -6) Back in the compose window: Add whatever other text you wish to the - message, complete the addressing and subject fields, and press send. - -7) Optionally, undo the about:config/account settings changes made in - steps 2 & 3. - - -[Footnotes] - -*1* Version 1.0 (20041207) from the MozillaThunderbird-1.0-5 rpm of Suse -9.3 professional updates. - -*2* It may be possible to do this with about:config and the following -settings but I haven't tried, yet:: - - mail.html_compose => false - mail.identity.default.compose_html => false - mail.identity.id?.compose_html => false - -(Lukas Sandström) - There is a script in contrib/thunderbird-patch-inline which can help you - include patches with Thunderbird in an easy way. To use it, do the steps above - and then use the script as the external editor. - -Gnus ----- - -'|' in the *Summary* buffer can be used to pipe the current -message to an external program, and this is a handy way to drive -"git am". However, if the message is MIME encoded, what is -piped into the program is the representation you see in your -*Article* buffer after unwrapping MIME. This is often not what -you would want for two reasons. It tends to screw up non ASCII -characters (most notably in people's names), and also -whitespaces (fatal in patches). Running 'C-u g' to display the -message in raw form before using '|' to run the pipe can work -this problem around. - - -KMail ------ - -This should help you to submit patches inline using KMail. - -1) Prepare the patch as a text file. - -2) Click on New Mail. - -3) Go under "Options" in the Composer window and be sure that - "Word wrap" is not set. - -4) Use Message -> Insert file... and insert the patch. - -5) Back in the compose window: add whatever other text you wish to the - message, complete the addressing and subject fields, and press send. - - -Gmail ------ - -GMail does not appear to have any way to turn off line wrapping in the web -interface, so this will mangle any emails that you send. You can however -use "git send-email" and send your patches through the GMail SMTP server, or -use any IMAP email client to connect to the google IMAP server and forward -the emails through that. - -To use ``git send-email`` and send your patches through the GMail SMTP server, -edit `~/.gitconfig` to specify your account settings:: - - [sendemail] - smtpencryption = tls - smtpserver = smtp.gmail.com - smtpuser = user@gmail.com - smtppass = p4ssw0rd - smtpserverport = 587 - -Once your commits are ready to be sent to the mailing list, run the -following commands:: - - $ git format-patch --cover-letter -M origin/master -o outgoing/ - $ edit outgoing/0000-* - $ git send-email outgoing/* - -To submit using the IMAP interface, first, edit your `~/.gitconfig` to specify your -account settings:: - - [imap] - folder = "[Gmail]/Drafts" - host = imaps://imap.gmail.com - user = user@gmail.com - pass = p4ssw0rd - port = 993 - sslverify = false - -You might need to instead use: folder = "[Google Mail]/Drafts" if you get an error -that the "Folder doesn't exist". - -Once your commits are ready to be sent to the mailing list, run the -following commands:: - - $ git format-patch --cover-letter -M --stdout origin/master | git imap-send - -Just make sure to disable line wrapping in the email client (GMail web -interface will line wrap no matter what, so you need to use a real -IMAP client). - -Working with Git -================ - -Extract a topic from pu ------------------------ - -pu is built this way:: - - git checkout pu - git reset --keep next - git merge --no-ff -X theirs topic1 - git merge --no-ff -X theirs topic2 - git merge --no-ff -X theirs blue - git merge --no-ff -X theirs orange - ... - -As a consequence: - -1. Each topic merged uses a merge commit. A merge commit is a commit having 2 - ancestors. Actually, Git allows more than 2 parents but we don't use this - feature. It's intended. - -2. Paths in pu may mix up multiple versions if all the topics don't use the same - base commit. This is very often the case as topics aren't rebased: it guarantees - each topic is strictly identical to the last version sent to the mailing list. - No surprise. - - -What you need to extract a particular topic is the sha1 of the tip of that -branch (the last commit of the topic). Assume you want the branch of the topic -called 'blue'. First, look at the log given by this command:: - - git log --reverse --merges --parents origin/next..origin/pu - -With this command you ask for the log: - -* from next to pu -* in reverse order (older first) -* merge commits only -* with the sha1 of the ancestors - -In this list, find the topic you're looking for, basing you search on the lines -like:: - - Merge branch 'topic/name' into pu - -By convention, it has the form /. When you're at -it, pick the topic ancestor sha1. It's always the last sha1 in the line starting -by 'commit'. For you to know: - -* the first is the sha1 of the commit you see: the merge commit -* the following sha1 is the ancestor of the branch checkouted at merge time - (always the previous merged topic or the ancien next in our case) -* last is the branch merged - -Giving:: - - commit sha1_of_merge_commit sha1_of_ancient_pu sha1_of_topic_blue - -Then, you only have to checkout the topic from there:: - - git checkout -b blue sha1_of_topic_blue - -and you're done! You've just created a new branch called "blue" with the blue -content. Be aware this topic is almostly not updated against current next -branch. ,-) diff --git a/docs/doc-src/dco.rst b/docs/doc-src/dco.rst new file mode 100644 index 0000000..83ae888 --- /dev/null +++ b/docs/doc-src/dco.rst @@ -0,0 +1,68 @@ + +Developer's Certificate of Origin +================================= + +v1.1:: + + By making a contribution to this project, I certify that: + + (a) The contribution was created in whole or in part by me and I + have the right to submit it under the open source license + indicated in the file; or + + (b) The contribution is based upon previous work that, to the best + of my knowledge, is covered under an appropriate open source + license and I have the right under that license to submit that + work with modifications, whether created in whole or in part + by me, under the same open source license (unless I am + permitted to submit under a different license), as indicated + in the file; or + + (c) The contribution was provided directly to me by some other + person who certified (a), (b) or (c) and I have not modified + it. + + (d) I understand and agree that this project and the contribution + are public and that a record of the contribution (including all + personal information I submit with it, including my sign-off) is + maintained indefinitely and may be redistributed consistent with + this project or the open source license(s) involved. + + +Then, you just add a line saying:: + + Signed-off-by: Random J Developer + +This line can be automatically added by git if you run the git-commit command +with the ``-s`` option.
