"git p4" updates. * ld/git-p4-updates: git-p4: auto-size the block git-p4: narrow the scope of exceptions caught when parsing an int git-p4: raise exceptions from p4CmdList based on error from p4 server git-p4: better error reporting when p4 fails git-p4: add option to disable syncing of p4/master with p4 git-p4: disable-rebase: allow setting this via configuration git-p4: add options --commit and --disable-rebase
2018-06-12git-p4: auto-size the blockLibravatar Luke Diamand1-6/+21
git-p4 originally would fetch changes in one query. On large repos this could fail because of the limits that Perforce imposes on the number of items returned and the number of queries in the database. To fix this, git-p4 learned to query changes in blocks of 512 changes, However, this can be very slow - if you have a few million changes, with each chunk taking about a second, it can be an hour or so. Although it's possible to tune this value manually with the "--changes-block-size" option, it's far from obvious to ordinary users that this is what needs doing. This change alters the block size dynamically by looking for the specific error messages returned from the Perforce server, and reducing the block size if the error is seen, either to the limit reported by the server, or to half the current block size. That means we can start out with a very large block size, and then let it automatically drop down to a value that works without error, while still failing correctly if some other error occurs.

2018-06-12git-p4: narrow the scope of exceptions caught when parsing an intLibravatar Luke Diamand1-1/+1
The current code traps all exceptions around some code which parses an integer, and then talks to Perforce. That can result in errors from Perforce being ignored.

2018-06-12git-p4: raise exceptions from p4CmdList based on error from p4 serverLibravatar Luke Diamand1-4/+40
This change lays some groundwork for better handling of rowcount errors from the server, where it fails to send us results because we requested too many. It adds an option to p4CmdList() to return errors as a Python exception. The exceptions are derived from P4Exception (something went wrong), P4ServerException (the server sent us an error code) and P4RequestSizeException (we requested too many rows/results from the server database). This makes the code that handles the errors a bit easier. The default behavior is unchanged; the new code is enabled with a flag.

2018-06-12git-p4: better error reporting when p4 failsLibravatar Luke Diamand1-0/+55
Currently when p4 fails to run, git-p4 just crashes with an obscure error message. For example, if the P4 ticket has expired, you get: Error: Cannot locate perforce checkout of <path> in client view This change checks whether git-p4 can talk to the Perforce server when the first P4 operation is attempted, and tries to print a meaningful error message if it fails.

2018-06-12git-p4: add option to disable syncing of p4/master with p4Libravatar Luke Diamand1-11/+20
Add an option to the git-p4 submit command to disable syncing with Perforce. This is useful for the case where a git-p4 mirror has been setup on a server somewhere, running from (e.g.) cron, and developers then clone from this. Having the local cloned copy also sync from Perforce just isn't useful. Signed-off-by: Luke Diamand <luke@diamand.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2018-06-12git-p4: add options --commit and --disable-rebaseLibravatar Romain Merland1-6/+23
On a daily work with multiple local git branches, the usual way to submit only a specified commit was to cherry-pick the commit on master then run git-p4 submit. It can be very annoying to switch between local branches and master, only to submit one commit. The proposed new way is to select directly the commit you want to submit. Add option --commit to command 'git-p4 submit' in order to submit only specified commit(s) in p4. On a daily work developping software with big compilation time, one may not want to rebase on his local git tree, in order to avoid long recompilation. Add option --disable-rebase to command 'git-p4 submit' in order to disable rebase after submission.

"git p4" learned to "unshelve" shelved commit from P4. * ld/p4-unshelve: git-p4: add unshelve command
2018-05-24git-p4: add unshelve commandLibravatar Luke Diamand1-36/+177
This can be used to "unshelve" a shelved P4 commit into a git commit. For example: $ git p4 unshelve 12345 The resulting commit ends up in the branch: refs/remotes/p4/unshelved/12345 If that branch already exists, it is renamed - for example the above branch would be saved as p4/unshelved/12345.1. git-p4 checks that the shelved changelist is based on files which are at the same Perforce revision as the origin branch being used for the unshelve (HEAD by default). If they are not, it will refuse to unshelve. This is to ensure that the unshelved change does not contain other changes mixed-in. The reference branch can be changed manually with the "--origin" option. The change adds a new Unshelve command class. This just runs the existing P4Sync code tweaked to handle a shelved changelist.

This then means that a git patch series can be mirrored to a sequence of shelved changelists, and (relatively easily) kept in sync as changes are made in git. Note that Perforce does not really support overlapping shelved changelists where one change touches the files modified by another. Trying to do this will result in merge conflicts.

2017-02-10git-p4: fix git-p4.pathEncoding for removed filesLibravatar Lars Schneider1-10/+14
In a9e38359e3 we taught git-p4 a way to re-encode path names from what was used in Perforce to UTF-8. This path re-encoding worked properly for "added" paths. "Removed" paths were not re-encoded and therefore different from the "added" paths. Consequently, these files were not removed in a git-p4 cloned Git repository because the path names did not match. Fix this by moving the re-encoding to a place that affects "added" and "removed" paths. Add a test to demonstrate the issue.

2017-01-30git-p4: fix git-p4.mapUser on WindowsLibravatar George Vanburgh1-1/+1
When running git-p4 on Windows, with multiple git-p4.mapUser entries in git config - no user mappings are applied to the generated repository. Reproduction Steps: 1. Add multiple git-p4.mapUser entries to git config on a Windows machine 2. Attempt to clone a p4 repository None of the user mappings will be applied. This issue is actually caused by gitConfigList, using split(os.linesep) to convert the output of git config --get-all into a list. On Windows, os.linesep is equal to '\r\n' - however git.exe returns configuration with a line seperator of '\n'. This leads to the list returned by gitConfigList containing only one element - which contains the full output of git config --get-all in string form, which causes problems for the code introduced to getUserMapFromPerforceServer in 10d08a149d ("git-p4: map a P4 user to Git author name and email address", 2016-03-01) This issue should be caught by the test introduced in 10d08a1, however would require running on Windows to reproduce.

git-p4 crashes when used with a very old p4 client version that does not support the '-r <number>' option in its commands. Allow making git-p4 work with old p4 clients by setting git-p4.retries to 0. Alternatively git-p4.retries could be made opt-in. But since only very old, barely maintained p4 versions don't support the '-r' option, the setting-retries-to-0 workaround would do.

When importing from multiple perforce paths - we may attempt to import a changelist that contains files from two (or more) of these depot paths. Currently, this results in multiple git commits - one containing the changes, and the other(s) as empty commit(s). This behavior was introduced in commit 1f90a64891 ("git-p4: reduce number of server queries for fetches", 2015-12-19). Reproduction Steps: 1. Have a git repo cloned from a perforce repo using multiple depot paths (e.g. //depot/foo and //depot/bar). 2. Submit a single change to the perforce repo that makes changes in both //depot/foo and //depot/bar. 3. Run "git p4 sync" to sync the change from #2. Change is synced as multiple commits, one for each depot path that was affected. Using a set, instead of a list inside p4ChangesForPaths() ensures that each changelist is unique to the returned list, and therefore only a single commit is generated for each changelist.

Git-P4 used to place temporary refs under "git-p4-tmp". Since 3da1f37 Git checks that all refs are placed under "refs". Instruct Git-P4 to place temporary refs under "refs/git-p4-tmp".

Use "git show-ref --verify" to check the (non-)existience of the refs instead of file checks assuming the file-based ref backend. All refs under "refs" are shared across all worktrees.
