* Add dependency handlingAndrew Robbins2019-10-181-4/+101
| | | | | | | | | | | | Dependencies for any project can be determined by calling project_dependencies() with a given project and (optional) arguments. This is the function you will almost always want to call when you're wanting to collect a list of dependencies. The output of the topological sort is only one possible ordering of those dependencies. 'dependencies' files may now contain any number of spaces or tabs between each argument.
* libs/project: Call functions from any projectAndrew Robbins2019-10-161-4/+8
| | | | | | | | | | Helper functions, such as "arguments", provided by one project should be callable from another project for more flexibility. Metaprojects in particular could use this functionality. In order for this to work, project_include() is used to create the necessary environment separation (so defined functions are not clobbered by the helper function).
* libs/project: Invoke subshell in project_function_check()Andrew Robbins2019-07-211-7/+6
| | | | | | | Since we're doing a simple check to see if a function exists in a given project's scripts we should only source those files into a subshell (so any changes to the environment are discarded once the subshell exits).
* Add functions to safely apply patches to non-git sourcesAndrew Robbins2019-07-162-1/+19
| | | | | | project_sources_patch() is the equivalent to git_patch() when working with non-git sources. It should not be used with sources under a version control system.
* Avoid redundant patching when recursively patchingAndrew Robbins2019-07-162-2/+2
| | | | | | | | If a path is not supplied to project_sources_patch_recursive() or git_project_patch_recursive() then it will attempt to apply the set of patches located at $PROJECTS/$project/$PATCHES (the top-level patches directory) twice. Checking to see if $path is of non-zero length avoids this issue.
* libs/project: Complete project_sources_prepare()Andrew Robbins2019-07-161-10/+61
| | | | | | | | The method in which project sources are prepared from either extracted non-git source archives or sources under $PROJECTS/$project/$SOURCES are comparable to preparing git sources. This makes knowledge of the source preparation process mostly transferable across the build system regardless whether git is involved or not.
* libs/project: Remove extraneous newlines in header/footerAndrew Robbins2019-04-261-3/+3
| | | | The extra newlines make actions with no output look strange.
* libs/project: Print project_action() footer, alwaysAndrew Robbins2019-04-261-10/+15
| | | | | | | | | | | | Previously, the footer would not print if the project action failed due to 'set -e' still being in effect (the subshell would return with a non-zero exit code and exit immediately). The purpose of the subshell for the project action is to better separate the execution environment of the project from the library functions it calls. The test condition in the if-statement and its consequents were changed in order to be more concise and informative.
* libs/project: Modify output of project_blobs_path()Andrew Robbins2019-04-231-2/+0
| | | | | | project_blobs_ignore_path() prints nothing if a blobs-ignore file is not found for the given project and arguments (if any); this behavior should be the same for project_blobs_path()
* Respect blobs-ignore when removing blobsAndrew Robbins2019-04-232-8/+18

* libs/project: Avoid subshell in 'if' statementsAndrew Robbins2019-04-181-1/+7
| | | | | | | | | | | | | | | | | | | | The following will effectively disable any previous 'set -e': foo_fail() { ( set -e false true ) } if (set +e; foo_fail); then echo "foo_fail() failed, unsuccessfully" fi Creating a subshell within an 'if' statement makes 'set -e' non-functional.
* libs/project: Fail update check for git sourcesAndrew Robbins2019-04-181-1/+1
| | | | | | | "update" actions were failing ever since revision b7fcc477 for projects with git sources due to an error in project_update_check_git() not returning 1 when it determined that the project's sources was a git repo (to force an update, always).
* libs/project: Fail install check, properlyAndrew Robbins2019-04-151-2/+7
| | | | | If the $install_path directory does not exist or a file which should be present in the install directory isn't, fail.
* libs/project: Fail build check, properlyAndrew Robbins2019-04-151-1/+6
| | | | | If the $build_path directory does not exist or a file which should be present in the build directory isn't, fail.
* libs/project: Don't fail with project_action_checkAndrew Robbins2019-04-131-1/+3
| | | | | | | | | project_action_check() is there to avoid redundant actions from being performed (e.g., if SeaBIOS is already built, don't build it again). Since this is its primary purpose, we want to avoid erroring out when it returns with a non-zero return code. This addresses issue #614

| * libs/git: Exit subshell upon "cd" failureAndrew Robbins2019-03-281-21/+33
| | | | | | | | | | | | If cd fails, nothing else should be done. This is to prevent a potentially destructive action from being performed on the Libreboot repository (if the script is executed from the same directory).
| * libs/git: Remove check from git_am() and git_apply()Andrew Robbins2019-03-281-6/+8
| | | | | | | | | | Having a specific function for checking whether a patch would apply isn't that useful if git_am and git_apply call it internally anyway.
| * libs/git: Commit only if any blobs were removedAndrew Robbins2019-03-271-1/+24
| | | | | | | | | | | | git_diff_check() was added for future use since it's complementary to git_diff_staged_check(). It could be used to check for a dirty worktree, for example.
| * libs/git: Fail if patching failsAndrew Robbins2019-03-271-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The recursive call in git_project_patch_recursive() is now performed last so that if a patching attempt fails, the calling functions won't attempt to apply more patches. The consequence of this change is that patches are applied in (nearly) opposite order from before. git_project_prepare_patch() is now called after git_project_prepare_blobs() so that if patching fails and the user chooses to perform additional project actions anyway, such as building, the project is already deblobbed and not a risk to their freedom. I had mistakenly reordered these function calls in a prior commit.
| * libs/project: Execute project action in subshellAndrew Robbins2019-03-261-13/+9
| | | | | | | | | | | | | | | | Executing the project action within its own subshell makes it easy to abort the action with a simple "exit" while still allowing for the printing of the footer describing failure/success. Prevously, if "exit" were called in a project action the footer would not print.
* | let's prefer pre-incrementAndrew Robbins2019-03-281-2/+2
| | | | | | | | | | The "let" builtin returns 1 if it's given an argument that evaluates to zero.

* libs/git: Remove unnecessary env invocationAndrew Robbins2019-03-231-2/+2
| | | | | LC_ALL is already set to "C.UTF-8" and exported if libfaketime path is given in libreboot.conf

* libs/git: Simplify logic for operating on branchesAndrew Robbins2019-03-231-122/+76
| | | | | | | Previous patches made certain tests unnecessary due to the setting of $BRANCH_PREFIX in $branch. By adding the branch prefix right before it's actually needed we can retain the usefulness of those conditional tests.
* libs/git: Avoid some redundancies in git_patch()Andrew Robbins2019-03-181-19/+29
| | | | | | | | | The subshell, changing directory, and checking out was unecessary considering all of these are done within the functions called by git_patch() git_am() was added in order to mirror the same wrapper style as used by git_apply() and git_commit()
* libs/git: Move patching method logic to git_patch()Andrew Robbins2019-03-181-8/+13
| | | | | | | | | | | This simplifies git_project_patch_recursive() and provides a unified method for patching, regardless of the patch format (mailbox or diff). Logic is included for dealing with patching failures due to git_apply_check() not being enough to catch certain edge cases, such as 'git apply --check' returning 0 but a subsequent 'git apply' failing.
* libs/git: Add git_apply() and git_apply_check()Andrew Robbins2019-03-181-1/+33
| | | | | | | | | | Since changes from an applied diff need to be added to the index and committed (vs. mailbox files with the git_patch function) new functions were necessary to account for this difference. This also fixes a bug where diffs were applied but not committed, at minimum dirtying the work tree and potentially causing problems for any later patches.
* Rename and refactor diff_patch_file()Andrew Robbins2019-03-183-17/+6
| | | | | | The previous function, diff_patch_file, was more error-prone and fragile and did not take into consideration patching of more than one file at a time(!).
* libs/git: Apply patches before removing blobsAndrew Robbins2019-03-131-1/+1
| | | | | | | | | Patching before removing blobs is cleaner since patches are applied against a freshly created and checked out branch at the specified revision. Applying patches first also seems to reduce the likelihood of failed patching attempts due to a nebulous error about files not matching the git index (but doesn't eliminate it). More debugging required.
* libs/git: Actually patch recursivelyAndrew Robbins2019-03-131-10/+10
| | | | | | | | | | | | | | | | Previously the only way patching would work is if for every target there existed a corresponding directory under $project/$PATCHES, e.g: "./libreboot update coreboot x200 8MiB corebootfb grub" would require the "grub" directory and its parents: "projects/coreboot/patches/x200/8MiB/corebootfb/grub" Now you only need target-specific patch directories if you need them; I believe this was the intended behavior. Superfluous quotes were removed for readability.
* libs/git: Create branch name based on argument listAndrew Robbins2019-03-121-18/+2
| | | | | | | | | | | | | | | | | | | | | There was a bug where only $project was used as the branch name due to some faulty logic which checked for the existence of a revision file before setting the variables "prepare_branch" and "prepare_path". The bug in this case was that prepare_branch would be set to the value of $branch in only the first iteration of the for loop since in almost all cases there is only one revision file that exists for a given project, regardless of the arguments provided. Explained another way, in order for the proper branch name to be used a revision file would have had to exist in every target directory. This was an issue because only one branch was ever operated on (named $project), meaning if actions were performed on many targets then only the last to run would be represented in the project's repository--making tracking down some bugs a bit harder. With this fixed we now create a branch for every possible project or tool configuration and leaves us with a log for each.
* libs/git: Prefix branch names with "libreboot-"Andrew Robbins2019-03-121-7/+8
| | | | | | | This is a slight mitigation against branch name collisions. More robust handling should be added in the future but this is simple enough and provides some clear indication which branches have been created by the build system.
* libs/git: Clean up after patch fails to applyAndrew Robbins2019-03-111-1/+2
| | | | | A patch failing to apply shouldn't leave the repository in such a state where manual intervention is necessary to reset it.
* Center tool/project output between header/footerAndrew Robbins2019-02-222-2/+2
| | | | Makes it easier to read when multiple terse actions are performed.
* Don't output header/footer to stderr unless necessaryAndrew Robbins2019-02-222-4/+7

* Add preliminary dependency handling supportAndrew Robbins2019-01-222-2/+74
| | | | | | | | | | | | | | Projects may now declare other projects it depends upon through the file "dependencies" located in a project's $CONFIGS directory. This file requires that each dependency listed, one per line, correspond to a project in the $PROJECTS directory; the dependency may be in any form accepted by the libreboot script, e.g: ./libreboot build $dependency Multiple dependencies files, one per target, are read provided they are located in target directories and those targets were included in the list of arguments passed to the libreboot script.
* Modify project_file_path() to return first matching pathAndrew Robbins2018-10-091-0/+2
| | | | | | project_file_path() now returns the first matching path rather than the last. This is necessary to allow splitting up configuration files for projects into "base" and "overriding" configs.
* Consolidate R400/T400/T500/W500 Coreboot configsAndrew Robbins2018-10-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The goal here is to have fewer full configuration files. By consolidating the T400 board configs (and board variants such as the R400/T500/W500) into at most two base configs we can rely on separate target-specific configs (e.g., for different flash sizes) to override our default values given in projects/coreboot/configs/t400/config File contents of the new configs located at projects/coreboot/t400/variants/ are now supplied to make as command-line arguments, overriding the same configurations in the base config. The T400 file is included as an example of which configurations need to be overriden by a variant for a proper SMBIOS name to be used. Configs allowing for different ROM chip sizes other than the default are reimplemented in a subsequent commit. The following are no longer valid targets when building Coreboot: r400_16mb r400_8mb r400_4mb t400_16mb t400_8mb t400_4mb t500_16mb t500_8mb t500_4mb w500_16mb w500_8mb w500_4mb
* Use project_sources_path() in archive creationAndrew Robbins2018-01-141-27/+4
| | | | | | | | | | | | Previously, the function 'project_release_sources_archive_path' assumed that a project's source files would always be located within "$root/$SOURCES" in a directory named after the project. However, this does not account for projects such as bucts whose source files are located in "$root/$PROJECTS/$project/sources". In order to address this, trivial changes were made to leverage project_sources_path() as it returns nearly all the information needed to create the path to the archive file.
* Remove unnecessary spaces in command substitutionsAndrew Robbins2017-10-284-96/+96
| | | | | | | | | This is likely one of the very last changes necessary to make the Libreboot build system more cohesive in appearance. Hopefully from this point forward it won't be as readily apparent as to who wrote which parts of the build system (i.e. won't look like a patchwork quilt any longer).
* Make use of Bash's '-n' operator for testsAndrew Robbins2017-10-284-40/+40
| | | | | | | | | | | | As an example, do this: [[ -n $revision ]] instead of this: ! [[ -z $revision ]] Makes the code easier to read.
* Replace usage of the '[' Bash builtin with '[['Andrew Robbins2017-10-284-99/+99
| | | | | | | | | | There's no benefit to using the POSIX-style '[' test builtin considering its '-a' and '-o' operators are unused in the Libreboot build system. Plus, '[[' is safer with respect to any containing file redirections (for example). Prior, both '[' and '[[' were used throughout the codebase--a disparity in usage which this change aims to eliminate.
* Replace '.' usage with Bash 'source' builtinAndrew Robbins2017-10-281-2/+2
| | | | | | | The source builtin provided by Bash is easier to read than '.' (a lone period). Conforming to POSIX wasn't and isn't a goal of the Libreboot build system and as such it's fine to deviate from the standard where it makes sense, such as now.

* Remove overlooked braces from parameter expansionsAndrew Robbins2017-09-221-1/+1
| | | | | | | | | | This is a continuation of the last set of commits removing braces from parameter expressions which do not require them. The main script was overlooked when applying the previous changes, which this commit aims to correct. Also, one parameter expansion in libs/common was corrected as it was overlooked as well.
